GE Home Alarm Security Systems #home #security #camera #monitoring #systems


Wireless alarm systems with constant monitoring are more affordable than ever and will give you the peace of mind you deserve.

An In Home security alarm monitoring system is a crucial part of building a new house, or upgrading an old one. In fact, if you are simply moving into a different, but not necessarily new, house, the alarm system and whether it is monitored should be a question you ask the previous homeowner.

Most people know enough to take basic precautions in protecting their home—like leaving an outside light on so neighbors can see an intruder if you are away, locking the doors, owning a barking dog, and password protecting a computer system. Many people try to keep valuables locked in a safe or at least hidden in a location they hope will be unsuspected. The problem with all of our personal efforts to practice safety is that we are human, and it is almost impossible to think of every opportunity that we might accidentally give to a burglar. That’s why we need the protection of a home security system that includes the services of a monitoring company. It is the company’s job to be alert when you cannot be, either because you are not home or because you are sleeping or simply caught off guard.

Buildings of all types, and even cars are burglarized every day. Some of the thieves are simply desperate people who may be unable to find work and have resorted to crime in an attempt to survive. Others, the more dangerous crooks, are professionals who know every trick in the book for staging a robbery on private property. Furthermore, the best crooks even know how to steal items that will be of great value to themselves but that you will have a hard time tracing once the items have left your home. Certain things like jewelry and antiques you don’t use every day might not even be missed until long after the burglar has pawned your belongings in a location far away from you. It just isn’t worth depending on yourself or your family members to be alert 24/7, 365 days a year. When you rely on a company to protect your home for you, just having a sign up indicating that you have a home alarm system will often deter a burglar

Thanks to the new wireless technology, a home alarm system can be installed in your home with only an hour or two of work. The monitored systems need to be installed by licensed professionals who can communicate with the company and check to make sure everything is working properly before they leave.

If you think you are mechanically inclined enough to install your own system, you can purchase an inexpensive wireless system at your local hardware store, but if it doesn’t do what you want, you are responsible for the results. Even with a professional system, however, you can get very reasonable prices and you can choose the features you want included. For example, if you already have a dependable fire alarm and/or sprinkler system, you may not want to pay an additional price to have a fire or smoke alarm included with your security alarm.

Of course, if you do not already have adequate protection for disasters other than burglary, you can get alarm systems that include flood warnings, smoke alarms, carbon monoxide sensors and more. You can also have closed circuit TV, so if you work in a place where you could take a glance at your home yourself, you might want to check that out. Just be aware that the more bells and whistles you include, the more expensive it will be. Furthermore, before worrying about the add-ons, you need to analyze your own home, counting the windows and doors that need protection. You also need to decide whether you want a silent alarm that only notifies the police, or one with a siren that will alert all the neighbors as well. If you live too far away from other homes, a siren will just give the crook time to grab what he can and get away before the police get there

Added benefit of s security system
In addition to protecting you against a break-in, a security system may also save you money by lowering the rates on your homeowner’s insurance. Some companies give as much as a 20% discount for having an approved security system. Furthermore, if you ever decide to sell your home, having a security system already installed and active could increase the value of your home. Finally, some alarm system monitoring companies give big discounts on the system itself—some even giving you the equipment for free once the system is activated—while others will knock off a month or two of service fees if you pay for the whole year at once.

Secure Your Home while Saving Money!
A house alarm security system has a secondary benefit that could help pay for itself in time. That is, you could be eligible for lower rates on your homeowner’s insurance. If your insurance carrier does not offer such a discount, you might consider shopping around, as many companies give as much as a 20% discount for having an approved, in home security system.

Network monitoring tools #small #network #monitoring #software


Network monitoring tools

Easy answer, Solar Winds! If you are looking for a free product, then you could use MRTG, or NMIS. But, if you are serious about monitoring your network, Solar Winds is the way to go, you can monitor servers, VM’s Switches Routers etc. If it has an IP address, you can monitor it with Solar Winds.I have used their products a number of times in the past. They have great support. I use their free tools as well.

    Fiber Optic Installation – Inspection and Copper Cable Testing Tools #it


    Punch Down and Termination Tools

    The best installations start with the best tools. And you can get the best tools from one trusted provider – Fluke Networks. Our network installation line encompasses all the essential tools needed for a job done right! From our innovative JackRapid™ punchdown tool to our forged steel constructed D-Snips cable scissors, look to Fluke Networks.

    Case Studies

    ITM, a UK-based leading independent provider of specialist ICT infrastructure solutions and services, applies best of breed technology, in-house expertise and innovation to deliver standards compliant solutions and services to clients throughout the UK, Europe and the rest of the World. Stuart Ayres, ITM Fibre & Equipment Engineer, reviewed the results of their investment in twenty Versiv Cabling Certification Systems.

    After using the Versiv System for a few months it clearly offers several advantages when compared to the previous generation of test equipment. Not only is the Versiv System faster, the modular design and online connectivity dramatically reduces our engineers travel time as they no longer need to call into the office to have test results downloaded or firmware updated.

    During the few months that we have been using the new equipment I have identified the following advantages that translate into productivity gains for both ITM and our Customers:

    • Greatly reduced test cycle times for both copper and fibre.
    • Easy and fast movement of test data from site to office enables better project progress reporting, quicker sign-off and invoicing.
    • Ability to remotely configure and control the test units.

    A Trusted Partner of Community Corrections, Courts, and Law Enforcement Since 1993

    I had to visit a Sentinel office earlier today to resolve an issue for my daughter who was in custody. As you can imagine, I was quite an emotional mess when I arrived at the Sentinel office today as I have never had to deal with an issue such as this. I met with the Sentinel Case Manager and she was so kind and extremely helpful that she made what started out as a very painful process so much easier to bear. I would like to commend her for true professionalism and her empathy to me as a mother concerned for her daughter and grandchildren who were affected by this whole ordeal.

    M. Andrews, Augusta, Georgia

    I am a Chief Attorney with the District Attorney’s office. I wanted to take a minute to tell you how much I appreciate working with the staff at Sentinel. In February, one of your staff members came to court to testify. The defendant was wearing a Sentinel GPS ankle bracelet, and your staff member was able to articulately explain how the technology works and placed the defendant exactly where the victim said they were. This is the third case that I have used Sentinel staff and each time they have been very professional and a pleasure to work with. Thanks!

    T. Muth, Wichita, Kansas

    I would like to say that you could not have hired a more reliable and professional staff for your local office. They were always available to answer any questions I may have regarding defendants that were ordered to be put on one of Sentinel’s electronic monitoring programs. Because of my position with the court, the great majority of correspondence I have had with your team was via e-mail. Anytime I sent something over to the Sentinel office, they always replied and let me know that they had received whatever I was sending. I have truly enjoyed working with them and wish all of them continued success with your company in the years to come.

    P. Hovden, Portland, Oregon

    The Riverside County Sheriff’s Department is extremely pleased with Sentinel as the vendor utilized for the application of our alternative sentencing programs. They are consistently willing to meet and discuss equipment issues or upgrades, software updates, or other improvements as necessary. Sentinel appears to have a solid grasp on the ever-changing nature of technology and is a terrific partner in working with us to meet the needs of our alternative sentenced population. The on-site Sentinel technician supplied to our agency is an extremely competent, hardworking employee. His expertise and work ethic is a valuable component to our alternative sentencing programs. In summary, working with Sentinel for the past several years has been a positive experience.

    Riverside County (California) Sheriff’s Department

    Our monitoring company has been using Sentinel Monitoring for over 16 years. Their professionalism and technology are invaluable to us. We greatly appreciate that their highly trained staff is available to us 24/7, as this is a huge asset to our line of business. We have needed Sentinel’s involvement in many high profile cases, and their employees have always provided the very personal and prompt attention these cases required. They have consistently been very diligent in returning every email and phone call in a timely manner. We definitely look forward to continuing this very successful business relationship for years to come.

    Sentinel has a professional, courteous and customer oriented staff! In addition, Sentinel has an outstanding product and they assist our department in a timely and efficient manner.

    Mac Mail not connecting to Exchange Server – Part 1 #mail


    Mac Mail not connecting to Exchange Server – Part 1

    Microsoft Outlook 2013/2016 clients on PC did not exhibit any issues. Latest Microsoft Outlook for Mac did not exhibit any issues either!

    It is worth pointing out that while Outlook 2013/2016 on PC use MAPI/HTTP or RPC/HTTP to connect to Exchange 2013/2016 servers, both clients on Mac (Mac‘s own Mail client and Microsoft Outlook for Mac) use EWS to connect.

    Mac Mail would show “Account Error” which read “Unable to connect … The server returned error: Connections to host on default ports failed.”

    The error is somewhat misleading as when you look at EWS logs on Exchange server, you see that the server rejected the request with HTTP error 400 which translated to “bad request”. What I didn’t know at that point is which element in the HTTP request was causing the server to reject the request.

    Microsoft provides great testing tools for Exchange on so I decided to run EWS connectivity test from the toolset. To my surprise, the test failed with the error “Message: The request failed. The remote server returned an error: (501) Not Implemented.”

    I knew about this particular error as I had worked with Michael Van Horenbeeck and is documented here:

    After enabling L7 debug tracing on my KEMP LoadMaster I observed the same error mentioned in the above articles “lb100 kernel: L7: badrequest-client_read [] (-501): ?xml. 0 [hlen 1405, nhdrs 11]”

    It would be easy to blame load balancer at this point and implement the recommended fix by changing 100-continue handling on LoadMaster. But if that was the issue, why did Outlook for Mac work without any errors?

    Anyhow, I proceeded changing the 100-continue handling by changing it from default setting of RFC-2616 compliant, to RFC-7231 compliant instead:

    After changing this setting, I ran the EWS test from exrca website again, and as one would expect, the test passed with no issues.

    It did, however, failed to address the issue for Mac Mail client! No eureka moment, just yet!

    I will cover details of further troubleshooting in second part of this article. You can read it here.

    Find Water Leaks with Thermal Imaging, Acoustics and Tracer Gas #water


    Leak Detecting Services

    How to Find a Water Leak

    Our highly trained engineers at L.D.S. Leak Detection Specialists Ltd. will choose the approriate testing and inspection process specifically chosen to suit your home or commercial business to find the leak.

    Our engineers at L.D.S. carry all the latest technology in leakage detection. We have listed the main Leak detection methods and equipment below. Inspection cameras. Protimeter mms damp meter survey kits, pressure gauges both hydraulic and digital and salts diagnostic kits also form part of the L.D.S. engineers equipment.

    Leak Detection Methods to Find A Leak

    Acoustic profiling uses ground and pipe sensitive microphones to enhance the sound of the leak. This method can help in pinpointing precise leak location.

    Is a way of finding and pinpointing leaks in water pipes. A leak in a pipe under pressure creates noise that travels through the pipe walls, the surrounding ground and along the contents of the pipe. Correlators are a very accurate sound testing device which are used to identify the acoustic frequency caused when a pipe is leaking. The correlator uses two identical sensors located along the pipe to calculate the leek location by logging the signal delay, sensor distance and the sound velocity.

    Tracer Gas
    The trace gas, a safe mixture of hydrogen and nitrogen, is introduced into the pipe with the suspected leak. The gas, is the lightest in the atmosphere and is made up of of small molecules. The gas will exit at the leak and make its way to the surface where it is detected using gas sensitive detection pobes.

    Thermal Imaging
    Thermography is the use of an infrared imaging and measurement camera to see and measure thermal energy emitted from an object. Thermography cameras can identify problem areas that can’t be seen with the naked eye, detecting hidden water leaks. The infrared inspection camera can detect not only hidden water leaks and their origin, but also moisture that cannot be physically reached with moisture meters. Read more

    Pipe, Cable and Metal Detection and Tracing
    Often the exact position of pipes and cables is unknown due to innacurate or non existant network plans. In order to carry out precise water leak detection and to avoid damage to utilities and operators during excavations, it is essential to know the precise position of all services. We use high performance equipment which can locate and trace buried pipes and cables.

    Network Monitoring with Noise Loggers
    Noise Loggers are used for early detection of leaks in water supply networks.The longer it takes to identify that a network is leaking the more revenue is lost and the greater the loss of precious water resources. In addition to the more conventional methods of leak detection the installation of permanent noise loggers has proved to be a cost effective tool in early identification of water loss. By permanently monitoring sections of the system, which have previously been proven leak free, it will alert you when a potential leak does develop. Read more .

    In network management terms, network monitoring is the phrase used to describe a system that continuously monitors a network and notifies a network administrator though messaging systems (usually e-mail ) when a device fails or an outage occurs. Network monitoring is usually performed through the use of software applications and tools.

    At the most basic level, ping is a type of network monitoring tool. Other commercial software packages may include a network monitoring system that is designed to monitor an entire business or enterprise network.

    Some applications are used to monitor traffic on your network, such as VoIP monitoring, video stream monitoring, mail server (POP3 server) monitoring, and others.

    Video Surveillance and The Law – The Cheating Spouse and Infidelity


    Video Surveillance and The Law

    In general, most video recordings are legal in the U.S. with or without consent. It is our belief that this includes video surveillance performed by a private investigator for purposes of documenting adultery, infidelity and unfatiful spouses.

    Laws do exist regarding Invasion of Privacy which deals with the area of expected privacy. These include areas such as bathrooms, locker rooms, changing/dressing rooms, bedrooms and other areas where a person should expect a high level of personal privacy.

    While the majority of laws dealing with video recording privacy issues tend to allow surreptitious recording and monitoring of video activity under most circumstances without notification of any of the parties involved, it is highly recommended that you consult with your local or state law enforcement or an attorney who specializes in this area to comply with all local and regulations prior to utilization of video surveillance and monitoring.

    Your private investigator is well versed in such laws and as a rule of thumb; you should not have to worry about this when hiring a professional investigator. Nonetheless, this may affect your case in some ways. It is important that you realize that unlike Hollywood s version of spousal surveillance, we will not peek into windows, hide in the bathroom, put a micro-camera under the door, etc. Will we NOT plant hidden cameras in cars, bed rooms or other places either.

    Some General Guidelines on video surveillance:

    Covert video surveillance is illegal when:

    • The subject has a reasonable expectation of privacy (4th Amendment rights) i.e. in a bathroom; motel room; changing room
    • If audio eavesdropping is also taking place

    Covert surveillance may be illegal when:

    • The person with authority over the premises has not consented
    • The reason for the video surveillance fosters an illegal purpose

    Covert video surveillance should be avoided when:

    • A less intrusive, legal investigative method is equally available.
    • Whenever you feel uncertain about the legality or ethics of installation.

    Note: the above information is based on the opinions and interpretation of the author and is for general informational purposes. This is NOT legal advice. Do not rely on any of this information without verifying same with your attorney.

    Important Information about Private Investigations:

    If you feel that your husband, wife, boy friend or girl friend is cheating on you, be sure to tell us eveything. As your private investigator, we are only able to get you the proof and evidence you need if you tell us the whole story. Anything less can have a dramatic affect on our ability to get you the information you seek. Although we are among the best private investigators in the industry specializing in infidelity and cheating cases who are recognized experts in court, we are not magicians! We cannot make things exist that don t. We cannot find infidelity where it does not exist and sometimes, despite signs to the contrary, there is no infidelity or it is too infrequent or too well hidden to be found.

    Accordingly, we do not guarantee any outcome on any case. is owned and operated by Advanced Surveillance Group, Licensed Private Detectives based in Detroit, Michigan. The agency works on cases nationwide and also contracts with licensed private investigators in other states as needed.

    Monitoring Exchange 2013 with SCOM 2012 (Part 2) #exchange #server #monitoring


    Monitoring Exchange 2013 with SCOM 2012 (Part 2)

    Table 1: List of servers

    Exchange 2013 Management Pack Pre-requisites and Considerations

    Before importing the Exchange 2013 MP into System Center Operations Manager, there are some pre-requisites that have to be met:

    You have one of the following versions of System Center Operations Manager deployed in your organization:

    • System Center Operations Manager 2012 RTM or later
    • System Center Operations Manager 2007 R2 or later
  • You have already deployed SCOM agents to your Exchange Servers.

    The SCOM agents on your Exchange Servers are running under the local system account.

    The SCOM agents on your Exchange Servers are configured to act as a proxy and discover managed objects on other computers.

    If you are monitoring Exchange Server 2013 Database Availability Groups (DAGs), ensure that all DAG members are monitored by Operations Manager.

    Before downloading and installing the Exchange Server 2013 MP, you might want to import some recommended additional management packs, such as (these are the ones I used):

    Add the Exchange servers as agent managed computers

    Adding the Exchange servers to monitor as agent managed computers is the first required step.

    1. Click the Administration tab and then click Configure computers and devices to manage on the Actions pane. This will start the Computer and Device Management Wizard (Figure 2). Click Next. choose Advanced Discovery (Figure 3) and select Servers Only from the Computers and Device Classes drop-down box.
    1. On the next window, browse for the computers you are adding (Figure 4) and click Next. Select Use selected Management Server Action Account (Figure 5), click Discover and wait for the discovery results (Figure 6). Figure 7 shows a brief summary that is displayed at the end of the wizard. It is mandatory that all systems running Exchange Server 2013 that are managed by Operations Manager use Local System as the Agent Action Account. Click Finish .
    1. If the agent installation was successful, on each Exchange server you ll be able to see the System Center 2012 Operations Manager Agent listed on the Programs and Features on Windows 2012 (Figure 8). A new service is also created, the System Center Management Service. as depicted in Figure 9.
    1. To enable Agent Proxy configuration on all managed Exchange servers, in the Administration pane, under Administration. Device Management. Agent Managed. right-click on each Exchange server (Figure 10), select Properties. then the Security tab (Figure 11), and check the box Allow this agent to act as a proxy and discover managed objects on other computers. This step will also make exchange cluster instances to appear in the Agentless Managed section (ensure that all physical nodes of the cluster are monitored). Repeat the process for every managed Exchange 2013 server in the list

    Create a new management pack for customizations

    The customizations and overrides of sealed management packs, such as the Exchange 2013 MP, are usually saved in the default management pack. As a best practice you should create and use an unsealed management pack for each sealed management pack that you want to override, as shown in Figure 12.

    Figure 12: Unsealed management packs

    Creating a new management pack for storing overrides has the following advantages:

    • It simplifies the process of exporting customizations that were created in your test and pre-production environments to your production environment.
    • It allows you to delete the original management pack without first needing to delete the default management pack.
    • It is easier to track and update customizations to individual management packs.
    1. In the Operations Console, click the Administration button. In the Administration pane, right-click Management Packs and then click Create Management Pack. The Create a Management Pack wizard displays.
    2. In the General Properties page (Figure 13), type a name for the management pack in Name. the correct version number in Version. and a short description in Description. Click Next and then Create .

    Install the Exchange Server 2013 MP

    With the recommended additional management packs already imported, download and install the latest Microsoft Exchange Server 2013 Management Pack (at the time of the writing of this article it was version 15.00.0620.018). You can find the latest Management Packs at the Microsoft System Center Marketplace .

    Let s look at the installation steps of the Exchange 2013 Management Pack:

    1. Download the management pack file and launch the Microsoft Installer (MSI) package on the selected SCOM server. Accept the license agreement, and click Next (Figure 14).
    1. Accept the default installation folder or select a new one. Click Next (Figure 15). The extraction process begins.
    1. When the extraction ends, click Close (Figure 16). When the installation is complete, the management pack files are copied to the System Center Management Packs folder.
    1. To import the Exchange 2013 MP, open the SCOM 2012 Operations Console. Click the Administration tab, right-click the Management Packs node and then click Import Management Packs (Figure 17).
    2. Click Add. Add from disk and then click No on the Online Catalog Connection window. Select all the files from the Exchange MP directory, by default C:\Program Files\System Center Management Packs (Figure 18), click Open and then click the Install button (Figure 19).
    1. The Import Management Packs page appears and shows the progress for each management pack. After the import process is complete and the dialog box displays an icon next to each Management Pack that indicates success of the importation (Figure 20), click the Close button. Click View and then Refresh. or press F5, to see the Microsoft Exchange Server 2013 management pack in the list of Management Packs.

    After importing the Exchange 2013 MP, it will start immediately discovering Exchange machines. So, if you browse to the Discovered Inventory pane on the Operations Console (Figure 21), all the Exchange 2013 servers should be listed. Notice that the Database Availability Group (DAG) is also listed, although its state is Not monitored. This is a normal behavior, since the physical nodes of the DAG are already being monitored.

    The Exchange 2013 MP adds 3 views to the Monitoring pane (Figure 22):

    • Active Alerts
    • Organization Health
    • Server Health

    Expand Microsoft Exchange Server 2013. and then click Server Health. Right click on one of the Exchange servers listed and click Open. Health Explorer. By default, the view is scoped to unhealthy child monitors (Figure 23). Click on Filter Monitors to clear the filter (Figure 24). Expand Entity Health to view the 4 health groups for Exchange Server 2013:

    • Customer Touch Points components with direct real-time, customer interactions (e.g. OWA).
    • Service Components components without direct, real-time, customer interaction (e.g. OAB generation).
    • Server Components physical resources of a server (e.g. disk, memory).
    • Key Dependencies server s ability to call out to dependencies (e.g. Active Directory).


    With the Exchange 2013 Management Pack imported, SCOM is now prepared to receive the escalated alerts from Managed Availability that require human attention.

    In the next part we ll take a deeper look into Managed Availability, specifically how to interact with it and perform some configuration tasks that used to be part of the process of installing and configuring the MP.

  • Server Monitoring Software (SaaS), Server Performance Monitoring Tools #saas #server #monitoring


    Server monitoring software (SaaS) from Anturis

    Deploy Windows and Linux monitoring in minutes and scale with ease

    Robust, yet simple and affordable, Anturis hosted server monitoring software (SaaS) for both Windows and Linux allows you to:

    • Easily set up monitoring of critical server performance metrics, applications, and networks.
    • Receive alerts notifying you of incidents.
    • Analyze historical and real-time server statistics.
    • Get an eagle s-eye view of the health of your entire infrastructure.

    A server monitoring tool that works perfectly for both in-house and cloud servers

    Anturis provides server performance monitoring for them all – physical Windows and Linux in-house servers as well as AWS, Microsoft Azure, Rackspace, and DigitalOcean off in the cloud.

    Set up server health monitoring by simply running a single shell command or through a standard Windows installer wizard – either will automatically install the agent and configure a typical server monitoring setup. There is no need to configure a SNMP daemon or WMI service. All that is required is to run the agent on your servers.

    Track important server metrics with ease

    • Server performance monitoring. CPU usage, CPU load, RAM, disk space, disk usage, SMART attributes.
    • Applications monitoring. MySQL database, Apache server, log files, custom scripts, swap usage, OS processes, Windows services, Active Directory, JVM, Windows Event Logs.
    • External and internal monitoring via the following protocols. ICMP, TCP, SSH, FTP, SMTP/SMTPs, IMAP/IMAPs, POP3/POP3s, HTTP/HTTPs.
    • Network monitoring. Ping, SNMP devices, packet loss, jitter, latency, printer, network interfaces.

    Email, SMS, and voice call notifications

    Anturis server monitoring tool offers customizable email, SMS, and voice call alerts and employs techniques that help eliminate false alerts and alert spam (multiple alerts for the same problem).

    Alerting can be configured according to:

    • Problem/incident severity.
    • Components dependencies.
    • Monitor status-change rules.
    • Warning and error thresholds.
    • Staff members responsibilities.

    Infrastructure schema view with impact-dependencies modeling

    Anturis server monitoring software allows you to built dependency charts that show how network devices, databases, servers, and other components are related, and can include such information in alerts.

    The hierarchical arrangement helps to avoid notification spam (in case several components fail at the same time) and to get an eagle s-eye view of the health of your entire infrastructure.

    External monitoring from multiple geographic locations

    Today s global economy means that your network must be available globally. Anturis employs global coverage to ensure that your websites, applications, and services are available from diverse regions and countries. Our multiple global locations allow you not only to monitor your servers’ availability, but also to compare the response time and full-web-page load time from various locations. Anturis maintains locations in the U.S. Canada, South America, Western Europe, Russia, China, and Singapore.

    Complete network monitoring

    Your network consists of more than just your servers, and the Anturis monitoring tool covers a wide variety of other tasks, such as checking for open ports, confirming the status and connectivity of your printers, and monitoring the QoS of your VoIP system. Anturis monitors virtually all SNCP-enabled devices, such as routers and switches.

    The best free parental control software 2017 #best #free #server #monitoring



    The best free parental control software 2017

    Keep your children safe online with the best free parental control software for Windows

    It’s hard to imagine anything less child-friendly than an uncensored internet. A rabid wolf, maybe, or a playground floored with broken glass and razor wire. The more connected we become the more we need everybody online – and that means trying to ensure that our children aren’t exposed to the very worst content, ideas and behaviour that exist online.

    Software can’t do everything, of course, but it can help to make parents’ lives much easier. These are our picks of the best parental control tools.

    1. Qustodio

    A full suite of parental control tools to protect kids from the worst of the web

    Most parental control software is aimed at Windows, but Qustodio (think ‘custodian’) is also available for Mac, Android. iOS, Kindle and (weirdly) Nook.

    The free version covers the basics, enabling you to set rules and time schedules, block pornography and other unsuitable content; if you go for the paid-for version that adds SMS monitoring, social media features and per-app controls. But even the free version is one of the most comprehensive parental control apps around.

    Its raft of features and support for a wide range of platforms make Qustodio the best free parental control software, but there are some other excellent free programs available, some of which may be better suited to your individual needs as a parent. Read on for our top choices.

    2. OpenDNS Family Shield

    Block domains on your whole home network at router level

    FamilyShield is a free service from OpenDNS. Its parental control tools automatically block domains that OpenDNS has flagged under the headings “tasteless, proxy/anonymizer, sexuality, or pornography”.

    One of the big pluses here is that while FamilyShield can run on PCs and mobile devices, you can also apply it to your network router and filter all the traffic that passes through it it’s just a matter of changing the DNS server numbers in your control panel.

    This has the happy benefit of improving DNS lookup speeds on some ISPs. By filtering everything at the router level, every device on your network benefits from the filters.

    3. Kidlogger

    Comprehensive activity logging so you know what your kids have been up to

    Nothing gets past Kidlogger. This free parental control software not only tracks what your children type and which websites they visit it also keeps a record of which programs they use and any screengrabs they take.

    If you’re concerned about who your kids might be talking to online, there’s even a voice-activated sound recorder. If your children are a little older and more responsible, you can pick and choose which options to monitor and give them a little privacy.

    The free software only covers one device and lacks some of the sneakier features of the premium editions (including silent monitoring of WhatsApp conversations and the ability to listen to phone calls), but it’s still a well-rounded tool if you’re concerned about your kids’ safety.

    4. Spyrix Free Keylogger

    Find out what the kids have been typing, and if they might be in trouble

    Keyloggers have something of a bad reputation online, as they’re often used by villains, but they can be a force for good too, and Spyrix ‘s features enable you to see what your children have been up to.

    Although it’s dubbed parental control software, it’s really a monitoring program; it doesn’t stop the kids getting up to no good, but it does let you see exactly what they’ve done.

    That means it isn’t really appropriate for younger children’s computers, but it may be useful for older children if you suspect online bullying or other unpleasantness.

    5. Zoodles

    A whole browser designed for younger kids, but quite easily circumvented

    The problem with many parental control apps is that they’re most effective for older children: while filtering adult content and other unpleasantness is obviously a good thing, there’s plenty of stuff that isn’t adult that can still scare younger children silly.

    Zoodles addresses that by combining filtered browsing and a dedicated web browser to create a walled garden: everything in it is safe for kids and there’s no risk of anything awful popping up.

    In addition to Windows, Zoodles is also available for Mac, Android and iOS, and a brand new version is currently in development.

    How the IIoT takes equipment inspection into the cloud #iiot, #condition

    How the IIoT takes equipment inspection into the cloud

    While connected machines share both production and process information, it is the equipment reliability inspection sensor technology that may prove to be the most interesting and challenging element of the IIoT. The amount of inspection data that can be generated by inline monitoring sensing technologies is impressive. So, the challenge is managing the volume and variety of data, while deriving value from it. Deriving value is where it gets interesting.

    Practitioners in vibration, motor current, thermography, ultrasound, and oil analysis (the five core PdM technologies) build up their knowledge, best practices, and ability to recognize tell-tale signs of common failure modes within various classes of equipment. When all the technologies are used together, and across multiple instances of common classes of equipment, patterns emerge in the larger population of data.

    Further, combining the data of all technologies along with years of PdM domain expertise promises to yield amazing predictive assistance to those of us charged with improving production capacity while lowering maintenance costs. Deriving this value with the emerging data analytics technologies of IIoT is what this author finds extremely interesting.

    Let’s take our best practices of inspecting our equipment with PdM technologies at a frequency greater than twice the expected arrival rate of equipment defects causing failure. In many cases, it is possible to use route-based inspection technologies, connecting our instruments to the internet after completing a day’s route. In other cases, due to accessibility, it is desirable to employ permanent sensing, including wireless or wired sensors. In even more complex cases, where operating conditions change frequently, it is desirable to employ intelligent data acquisition systems that are able to detect each operating condition, collect appropriate inspection data, and label the inspection with the operating condition.

    Now that the inspection data is collected, the typical approach is to employ one or more trained analysts to review the data, using traditional analytical tools, to create an assessment report of the equipment’s health. Some analysts are so good at reviewing their domain’s data, the pattern matching analytics between their ears helps to speed the process. However, not all analysts have the experience and training to make rapid interpretation, and as such, analysis becomes the bottleneck to deriving value from our highly-instrumented equipment. What is needed is an analytical engine that recognizes the tell-tale patterns in inspection data, coupled with documented domain expertise, including possible and likely failure modes of the equipment.

    When data is assembled in a large computing platform (a cloud computing platform), inspection data from common classes of equipment, operating in similar operating conditions, tends to cluster into patterns of normal or healthy patterns and patterns of common failure modes. Our human analyst then is greatly assisted by cloud computing technology. The bottleneck separating big inspection data from value begins to diminish.

    About the Author: Preston Johnson

    Adding to the data science analytics portfolio, we add our documented body of knowledge from our maintenance libraries. These libraries contain known failure modes, failure codes, and associated inspection technologies that detect the defects leading to equipment failure. Building on our inspection technology training (the training that produced the analytical power between our ears), we create expected pattern templates to help our data science analytics learn more quickly. This is known as “supervised machine learning.” The human analyst now has an apprentice, learning from real-world data as well as from our historical domain knowledge.

    The combination is powerful. As owners/operators of equipment who are challenged to staff each facility with the appropriate manpower for PdM inspection and analysis activities, we are relieved of the associated stress knowing that proven data and analysis technologies are automating PdM on our behalf. Further, there is a human in the machine who we can talk to, who appears at our monthly meetings, and who is in charge of the work his apprentice is conducting.

    Monitor Network Speed and Uptime with a Server Uptime Monitor #server


    Server Uptime Monitor

    sMonitor is a server uptime monitor for your business. Since many businesses these days offer services based on application services to their customers, it is extremely important that network administrators know that all of their essential servers are up and running. sMonitor will inform you of this. sMonitor runs as a standard Windows application or as a Windows service. Since it can run as a Windows service, it can also run in the background even if no one is logged into the computer. It monitors all network servers and informs network administrators by using either an SMTP email service or a GSM SMS messaging service if a server comes online, goes offline or has its running state modified in any other way. This way, network administrators will always know about the online status of their servers in minimal time.

    The main sMonitor window, whether being displayed on not, is mirrored by a constantly updated HTML file which keeps a log of all monitored activity. This file is fully customizable from within the program and it may be uploaded to any remote Web server that uses the FTP protocol. A built-in script interpreter interacts with remote systems using either a modem or the telnet service to launch third-party software.

    Additional features of sMonitor include its support for ICMP, UDP and TCP protocols. It can also send protocol-specific UDP requests to ports 67 (DHCP), 123 (NTP), 137 (NETBIOS-NS), 161 (SNMP) and 389 (LDAP). sMonitor can also provide alerts of a server’s uptime status by way of alarms, both audible and visible. Network administrators can receive customized email messages from the software. sMonitor also creates log files in the plain text format and the universally supported CSV (Comma Separated Values) format. Files are sorted by servers and services. More advanced users may also create custom scripts and debug them as required. The server uptime monitor provides a wealth of unique features making it one of the top-end solutions of its kind. It has many more features and a wide selection of different notification features when compared to similar programs.

    The standard method of checking a server’s uptime using the Windows operating system is simply a matter of using the ping command. However, this is extremely limited and offers absolutely no logging or automated functionality, making it useful only in very specific purposes. When you need to monitor the uptime of one or more servers constantly, sMonitor presents an essential solution that every network administrator will find use for. Another standard solution is the PortQry utility available from Microsoft. It offers more sophisticated functionality than the ping command, but it is still limited and there is no user-friendly GUI provided since it is simply a command line utility. Neither of these solutions provide any functionality to automatically alert the user as to the uptime status of a server, however.

    You can learn more about this server uptime monitor at A list of features is available here along with screenshots of the working software.

    • Runs as a standard application or a Windows service.
    • Runs as a system tray application automatically on startup.
    • Supports ICMP, TCP and UDP.
    • Sends protocol-specific UDP requests to the ports: 67 (DHCP), 123 (NTP), 137 (NETBIOS-NS), 161 (SNMP), 389 (LDAP).
    • Allows server lists to be saved and opened as user specified files.
    • Alerts by audible and visible alarms.
    • Allows SMTP (SSL) mail and SMS notifications when a service is down, up, or its state is changed.
    • Allows custom e-mail and SMS message format to be created.
    • Launches third-party applications.
    • Creates an HTML status file which mirrors the main sMonitor window.
    • Allows the HTML file to be customized and to be uploaded by FTP to a remote web server.
    • Contains a built-in script interpreter which interacts with remote systems by modem and telnet.
    • Allows customs scripts to be created and debugged.
    • Generates plain text log files and CSV format files sorted by servers and services.

    Are you in need of a tool that can constantly verify your network connectivity? Try sMonitor. It is a dependable application that periodically checks your TCP and UDP ports. This smart piece of software can be incredibly useful so why not try it right now?

    Solaris memory management – Performance issue #solaris #performance #monitoring


    Solaris memory management Performance issue

    Memory bottlenecks are evidenced by two different things happening on the system paging and swapping. Paging refers to pages of memory being reclaimed by the page daemon when the system starts to get low on free memory. Swapping is more extreme, and refers to entire processes being swapped out.

    To determine if you are only paging, or also swapping, examine two columns in the vmstat output. The first column is the sr (scan rate) column. If the value in this column is greater than zero then the page scanner is scanning memory pages to put them back on the free list to be reused. The page scanner runs when memory falls under the value of a system parameter known as lostfree default value is 1/64 th of physical memory or cachefree if priority_paging is enabled default value is 1/128 th of physical memory.

    You should not worry about high scan rates if you are using the file system heavily. High scan rates can be normal in many circumstances. If priority_paging is enable, the page scanner steals the pages more effectively so the file system I/O does not cause unnecessary paging of applications. priority_paging causes sr rate to be higher for its own good. Solaris 8 introduces the cyclic cache. With cyclic cache, the scanner is not used to reclaim pages during file system I/O therefore if sr is greater than 0 then it s a indication that the system is running low in memory.

    To see if the system is swapping, refer to the w column. It is the third column of the output, and refers to entire processes which are swapped out. You can determine what these processes are by running the command /usr/bin/ps -e -o pid,rss,args and looking for a RSS of 0 (sched, pageout and fsflush processes should always have a RSS of 0).

    If you have anything in the w column, the system is either low on memory right now, or have been in the past. If your system gets low on memory and processes are swapped out, it may take a long time for them to get back into memory.

    This is especially true if there are daemons running infrequently, because they have to receive an event in order to try to run again. This is not necessarily bad, as long as when they need to run, they will have the memory to do so.

    If, over time, you see swapping, you should probably consider adding memory to the system or devising a strategy to lower overall memory usage on the system.

    1. Check any degraded memory on the system using below command.

    Login to console and execute showstatus command. (I.e the server type is M series )

    If you see degraded part,then raise support case with oracle to replace the unit.

    2.Execute the below command to find the scan rate and system swap activity by executing the below command.

    3.The below command will help you to identify which local zones are using more memory.

    SAFE SECURITY – Security Alarm System Components #alarm #systems, #security, #burglar


    At SAFE Security we design home security systems that are tailored to meet the specific needs of each customer s home and lifestyle. We have wired and wireless systems available and all our systems are easy to use. Our systems can be configured to protect your home against intrusion, fire, carbon monoxide and other environmental hazards. When triggered, these devices send an electronic signal to the monitoring station where a trained operator will respond appropriately.

    The most commonly used devices include:

    Security System Keypads
    Keypads are an important part of your home security. They allow you to arm your system with a secured code. They can be placed wherever you need them most and are so easy to use even your children can operate them.

    Keypads feature emergency buttons that allow you to call for help immediately. Backlit buttons allow you to see your keypad when the power is out.

    Door and Window Sensors
    According to the NBFAA, 56% of burglars enter through a door, another 23% through the first floor window. Door and window sensors are placed in these areas of vulnerability. When the contact is broken, the alarm is triggered. A chime function allows you to monitor who comes and goes from your home—this is great for added security while you are at home. Keep children in and intruders out.

    Motion Detectors
    Motion Detectors are triggered when someone walks in view of the detector. If an intruder enters your home through a door or window that is not protected by a sensor, the motion detector will act as a trap ensuring they don’t stay in the home for long.

    Motion Detector technology can distinguish the difference between an intruder and a playful cat or dog left in the home. They can be turned off while you are home while your windows and doors can remain secured.

    Monitored Smoke Detectors
    During a fire it takes the average person seven minutes before they have an opportunity to call the fire department, but it takes just three minutes for a room to become fully engulfed in flames. With a monitored smoke detector, the second smoke is detected the siren will be triggered, the monitoring station will be contacted and the fire department dispatched. This allows you to focus on getting your family out of the home.

    Smoke detectors provide the best early warning for fire protection and ensure that your home is protected while you are at home or away.

    Carbon Monoxide Detector
    Carbon monoxide poisoning is the #1 cause of accidental poisoning in the United States. You can’t see it, smell it or taste it, but our Carbon Monoxide Detectors can. When high levels of carbon monoxide are detected the monitoring station is signaled and alerts your family. Protect your family against this silent killer with a Carbon Monoxide Detector added to your home security system.

    Panic Buttons
    Panic Sensors are designed to go just about anywhere. This sensor allows you to activate a 24-hour emergency alarm whether you are at home, in the yard, or in the shower. Call for help with just a push of a button.

    Remote Entry Key Fob
    Convenient and easy to use remote entry key fobs allow you to arm and disarm your system with a push of a button as far as 500 feet from your home. The key fob also features a panic button which allows you to contact help in case of emergency.

    Alarm Sirens
    An alarm siren provides peace of mind for you and acts as a deterrent for would-be intruders. Alarm sirens will wake even the soundest sleepers to alert them of trouble.

    How Radioactive is Our Ocean? #phytoplankton #monitoring #network


    is our ocean?

    The release of radioactive contaminants from Fukushima remains an unprecedented event for the people of Japan and the Pacific Ocean. Help scientists at the Woods Hole Oceanographic Institution reveal the ongoing spread of radiation across the Pacific and its evolving impacts on the ocean.

    Help Fund a Location

  • Propose a Location

  • View Current Results


  • News and


    How does it work?

    Help us by mobilizing your community, school, or social networks to raise the money it takes to analyze 20 liters (about 5 gallons) of seawater for signs of radiation from Fukushima. We’ll send you everything you need to take a sample and return it to us.

    Educate Yourself

    Should I be worried?

    The ocean contains many small sources of naturally occurring radiation that in most places exceeds the dose provided by radioisotopes released from Fukushima. In addition, the remnants of nuclear weapons testing in the 1960s and 70s are also still detectable around the world. Except for locations on land in Japan and sites near the Fukushima Dai-ichi nuclear power plant, all of these sources combined pose little risk to human health. [ MORE ]

    To describe the level of radiation in seawater samples, we use Bequerels (Bq), which equal the number of radioactive decay events per second, and report this number per cubic meter (1,000 liters or 264 gallons) of water. A typical sample will likely contain less than 10 Bequerels per cubic meter (Bq/m 3 ) from cesium-137, thousands of times less than the radioactivity produced by naturally occurring isotopes such as potassium-40. By comparing the amount of cesium-137, which has a relatively long 30-year half life, and cesium-134, which has a much shorter, 2-year half life, we can fingerprint the contamination from Fukushima and estimate how much was released into the Pacific.

    To understand exposure. we need to consider this number as well as the type of radiation produced (alpha particles, beta particles, or gamma rays) and the method of exposure (external or internal). Exposure is reported in Sieverts (Sv) or, more commonly, milli-Sieverts (mSv, or 0.001 Sv). Background radiation—the amount we receive from cosmic rays—amounts to 2 mSv at sea level. A single dental x-ray provides an exposure of as low as 0.005 mSv. [ LESS ]

    How radioactive is our ocean?

    impacts of radiation in the ocean

    WHOI senior scientist Ken Buesseler discusses the presence and effect of radiation from Fukushima on the ocean and marine life.

    Fukushima Plume predictions

    Radioactive contaminants from Fukushima are carried across the Pacific Ocean by currents, the strongest of which is the Kuroshio, and spread along the West Coast of North America by complex coastal processes. Models predict that radionuclides from Fukushima will begin to arrive on the West Coast in early 2014, mainly in the north (Alaska and British Columbia) and then move further south in coming years before appearing in Hawaii in small amounts. The concentration of contaminants is expected to be well below limits set by the U.S. EPA for cesium-137 in drinking water (7,400 Bq/m 3 ) or even the highest level recorded in the Baltic Sea after Chernobyl (1,000 Bq/m 3 ).


    The background level of radiation in oceans and seas varies around the globe. Measured in atomic disintegrations per second (Becquerels) of cesium-137 in a cubic meter of water, this variation becomes readily apparent. The primary source of cesium-137 has been nuclear weapons testing in the Pacific Ocean, but some regions have experienced additional inputs. The Irish Sea in 2008 showed elevated levels compared to large ocean basins as a result of radioactive releases from the Sellafield reprocessing facility at Seacastle, U.K. Levels in the Baltic and Black Seas are elevated due to fallout from the 1986 explosion and fire at the Chernobyl nuclear reactor. By comparison, EPA drinking water standard for cesium-137 is 7,400 Bq/m3.

    What About Marine life?

    Mouse over the numbers to learn more

    Radioisotopes released into the atmosphere from the Dai-ichi nuclear power plant fell into the ocean.

    Water used to cool reactors flushed radioisotopes into the sea.

    Microscopic marine plants (phytoplankton) take up radioisotopes from seawater around them.

    Contaminants move up the food chain from phytoplankton to tiny marine animals (zooplankton), fish larvae, fish, and larger predators. Different radioisotopes are taken up at different rates by different species.

    Some contaminants end up in fecal pellets and other detrital particles that settle to the seafloor and accumulate in sediments.

    Some radioisotopes in sediments may be remobilized into overlying waters and absorbed by bottom-dwelling organisms.

    Scientists are tracking the many pathways by which radioisotopes from the damaged nuclear reactors at Fukushima make their way into and out of seawater, marine life, and seafloor sediments. These depend on the behavior and metabolism of individual animal, the nature of complex coastal and open-ocean processes, and the physical and chemical properties of individual isotopes.

    Tale of the Tuna

    Most marine life that becomes contaminated with Fukushima radiation remains near the reactor, but some species, like Bluefin tuna, are far-ranging and even migrate across the Pacific. When these animals leave the Northeast coast of Japan, some isotopes remain in their body, but others, like cesium, naturally flush out of their system. (Credit: Madigan, Baumann, and Fisher )

    News & Events

    About this Project

    The world’s oceans contain many of naturally occurring radioactive isotopes, as well as the remnants of nuclear weapons testing in the 1950s and 60s. Starting in 2011, fallout, runoff, and continued leaks from the Fukushima Dai-ichi nuclear power plant added to this baseline and sparked fears of wide-ranging impacts to the marine ecosystem and human health. Despite concerns, there is no U.S. government agency monitoring the spread of low levels of radiation from Fukushima along the West Coast and around the Hawaiian Islands—even though levels are expected to rise over coming years.

    Whether you agree with predictions that levels of radiation along the Pacific Coast of North America will be too low to be of human health concern or to impact fisheries and marine life, we can all agree that radiation should be monitored, and we are asking for your help to make that happen.

    The Woods Hole Oceanographic Institution has both the experience and facilities to monitor and track the spread of radionuclides released from Fukushima in the waters of the Pacific Coast of North America. The Institution and the Center for Marine and Environmental Radiation (CMER) are uniquely equipped to provide consistent, accurate assessment of both natural and manmade radiation in marine samples and is hosting this site to make this information readily available to everyone in a timely manner.

    We live in a Sea of radioactivity.
    The danger is in the dose.

  • WiFi Monitoring Software PRTG #wifi #network #monitoring #software


    PRTG: Professional
    WIFI Monitoring Software

    . with PRTG you get much more

    For many, wireless network monitoring is just one component of their monitoring structure. There can be many reasons for your Internet connection being down or disrupted. With PRTG, you get a monitoring tool which features an extensive framework. This framework allows you to discover unconventional sources of errors, sources you may not have searched for right away. And that means you’ll save precious time.

    Here are three examples:

    Internet Accessibility

    Does your Internet connection work only most of the time? Could the problem lie with your service provider, and not with your routers, switches, or access points? The Common SaaS senso r will provide you with the answer. This sensor queries various large sites such as Facebook, Dropbox, or YouTube, which in general are never offline.

    Disruption in Email Traffic

    Nothing makes co-workers complain faster than the inability to send or receive emails. In such a case, the LAN or wireless network may be the culprit. But email issues could also be due to SMTP or POP3 protocol disruptions. PRTG features a variety of predefined and individually configurable sensors to monitor your mail server. Find our more in our sensor list .

    Website Accessibility

    The Cloud HTTP sensor monitors the load time of your site on a variety of servers found on different continents. This sensor lets you see if your site is also accessible from abroad. Tokyo, Ireland, North Virginia, and Oregon are a few of the places where these servers are found.

    “Hey Gerald, what would you tell administrators looking to use PRTG to monitor their wireless network?”

    “Those looking to combine several monitoring statuses into one can use our Business Process Sensor. With this sensor, several sensors – such as for the router, access points, and other end devices – can be represented under a single, comprehensive sensor status. This means it only takes a quick glance to see if everything is alright.”

    Gerald Schoch works as a technical editor at PAESSLER AG.

    LAN Monitoring

    LAN monitoring is the basis for a reliable, high-performance network. Many administrators still think they can do without a monitoring tool. But after a disruption or crash, these same administrators often search frantically for good monitoring software. Other administrators use several monitoring tools concurrently but eventually opt for PRTG to benefit from a single, central, efficient, and easily upgradeable tool.

    WiFi Network Monitoring

    These days, many businesses and organizations operate on the “bring your own device” principle. Tablets, smartphones, and other mobile devices must however also be granted access to the WiFi network. Furthermore, laptops are often used for presentations in conference rooms and likewise require an Internet connection. As a result, WiFi monitoring quickly becomes an important issue for administrators.

    WAN Monitoring

    Wide area networks are especially susceptible to crashes and disruptions, for they are spread out across rooms, countries, and even continents. At the same time, a great deal of important data (such as internal applications, emails, and VoIP telephony) flows across a WAN. Getting started with WAN monitoring can therefore truly be a lifesaver.

    Over 95% of our customers recommend PRTG

    Paessler AG submitted an extensive survey to interview more than 600 IT departments worldwide who use PRTG. The goal of this survey was to optimize and fine-tune our Network Monitoring Software to better meet the needs of administrators.

    One survey result: more than 95% of the participants would recommend PRTG – or have already done so.

    How have network performance monitoring tools evolved? #network #performance #monitoring #tool


    How have network performance monitoring tools evolved?

    Once upon a time, enterprise network engineers had to provide network access and sufficient bandwidth to various connected servers, applications and end devices. From an OSI model perspective, the focus was on Layers 1-4 only. Upper OSI layers were more or less ignored, as all traffic and data flows running across a network shared all bandwidth and queuing resources.

    As time went on, network equipment became sophisticated to the point where different data flows could be identified and treated differently on the network. Various quality of service (QoS) and application-level traffic shaping techniques can be used to accomplish this goal. Additionally, the ever-increasing reliance on business-critical applications has forced network engineers to understand upper layers of the OSI model so they can help to identify any inefficiencies or problems related to the network, server OS, virtualization software and applications themselves. But in order to do that, a tool is needed to identify such problems.

    So, it’s important to understand exactly what your organization needs — and properly gauge the tradeoff between granularity and complexity.

    In many cases, network performance monitoring tools evolved from more traditional and less sophisticated network monitoring software. These monitoring tools commonly used ICMP ping and Simple Network Monitoring Protocol (SNMP) polling/traps to verify the health of a network. More modern additions include the ability to monitor, baseline and intelligently analyze possible images all the way to the application itself. Most modern network performance tools have the ability to perform the following five functions:

    1. Network and application monitoring
    2. Network problem analysis
    3. Application data and flow capture analysis
    4. Virtualization and OS problem detection
    5. Root cause analysis

    Depending on the network performance monitoring vendor, these tasks are performed with varying levels of granularity. And the more precise they are, the more complex implementation and management can be. So, it’s important to understand exactly what your organization needs — and properly gauge the tradeoff between granularity and complexity. That being said, let’s further explore the five functions today’s network performance monitoring tools commonly offer.

    Network and application monitoring

    As mentioned earlier, today’s network performance monitoring tools evolved from network monitoring that leveraged ICMP ping and the SNMP protocol. Routine pings from the network monitoring server were sent to various networks, servers and other end devices that required monitoring. If the monitored device stopped responding to the ping requests, the monitoring tool would mark the device as down and would alert support staff.

    SNMP collects and organizes various types of data from network and server components capable of supporting the protocol.

    For network devices, this commonly means monitoring specific device interface states and data throughput rates over time. It can also monitor hardware health, including power supplies, fans and memory utilization, among others.

    Some network performance monitoring tools are also capable of collecting and triggering from various syslog messages. Syslog is a common standard for infrastructure device log messages. The messages are sent to the centralized network monitoring tool to be stored, analyzed and used to notify support engineers in the event of a system malfunction.

    Network monitoring tools have the beefed-up capability to monitor availability and performance statistics all the way up to the application level. This type of monitoring usually relies on software plug-ins or OS settings configured to send monitoring data back to the centralized monitoring server.

    Virtualization and OS problem detection

    Issues also can — and do — arise between the network and the application. This includes problems at the virtualization level, server operating system and any middleware the application relies on to operate. Virtualization hypervisors can be individually monitored for performance problems that can cause slowdowns at the application level. The same is also true for monitoring the host OS and middleware that orchestrates communication over distributed systems. Network performance monitoring vendors use differing methods to monitor these types of problems and some support a greater variety of hypervisors, operating systems and middleware software than others.

    Network problem analysis

    In addition to providing simple up/down status and utilization information, network performance monitoring products can perform more sophisticated and automated network troubleshooting. This includes routing protocol monitoring and alerting when unscheduled routing protocol changes occur. Additionally, some products possess intelligence to understand how various WAN technologies, virtual overlays and QoS features operate. They, too, can be set to automatically alert when problems occur and even take automated actions to resolve issues.

    Application data and flow capture analysis

    The most important duties of modern network performance monitoring tools revolve around data and flow capture analysis. There are a few different methods to capture data packets on various parts of the network to be used for automated and/or manual analysis. Among the most common:

    1. Deployment of distributed data collection agents throughout critical parts of the network
    2. The ability to leverage packet capture functionality built into certain router/switch hardware

    The ability to examine packets to perform more granular application analysis is a growing need in many enterprise organizations. By using deep packet inspection. network administrators can identify more application-related communication problems that would otherwise go unnoticed.

    Network flow collection sweeps up IP network statistics as data enters and exits network interfaces. Once this data is exported to a centralized server and analyzed using network performance monitoring flow analysis tools, network support administrators can identify traffic source and destination information, as well as detail QoS policies the traffic encounters as it traverses the network. Ultimately, the data can be used to identify any configuration issues or congestion along various network paths. between network devices.

    Root cause analysis

    The ability to combine various events collected and analyzed on a network performance monitoring tool can also be used to form an automated root cause analysis. If an issue occurred on the network that triggered events on multiple components, many network performance monitoring tools use artificial intelligence to correlate the events and determine a likely root cause to the problem. This is one of the trickier functions to configure, since it requires all devices and monitoring systems be configured perfectly. For example, if device times are not synchronized using the Network Time Protocol. event times will be incorrect. This can negatively affect the accuracy of the root cause analysis engine. But once set up and properly maintained, automated root cause analysis tools can save a tremendous amount of time from a troubleshooting perspective.

    13 Free Open Source NetFlow Analyzers (Windows #network #device #monitoring #open


    13 Free Open Source NetFlow Analyzers for Windows and Linux/Unix

    Looking for a Free Open Source NetFlow Analyzers for Windows, Linux or Unix? Look no further, we ve compiled the ultimate list of Open Source tools to help with your network monitoring tasks. As many of you already know, NetFlow is a protocol/standard developed by Cisco for collecting/transferring/analyzing network data using software packages to get a better understanding of what is happening on your network, along with further analysis of bandwidth usage, etc.

    Netflow allows administrators to take the processing of network data away from switches and routers and send the flow packets and information to a collector that further analyzes that data to free up resources on the network device itself.

    There are many commercial Netflow (or sflow, jflow, rflow, cflow, or netstream) that are Available for Free Download and use that we ve recently detailed in this post that are also Free of charge too. These Software packages are great if you are just getting into network analysis using Netflow, as they are designed to be Very user friendly and can be setup in relatively little time. Check them out HERE if you want to see what they re all about.

    On the other hand, if your looking for an Open-Source alternative, you re in luck We ve put together a large list of Free Open Source Netflow Analyzers/Collectors to help you collect, analyze and scrutinize traffic and bandwidth to help you keep track of whats going on in your network.

    Using a open source network analyzer/collector allows you the flexibility of customizing the software packages and reports as you wish if necessary. These software packages can be used on a wide variety of operating systems including Windows and Linux/Unix.

    Open Source Netflow Tools/Analyzers

    NTop (or Ntopng)

    Probably the most well-known open source traffic analyzers, Ntop, is a web-based tool that runs on Ubuntu x64 versions, CentOS/Redhat x64 Linux flavors, Windows x64 Operating systems, BeagleBoard ARM, Ubiquity networks EdgeRouter and even Mac OSX per their github site. nTopng also includes suuport for sFlow and IPFIX (through nProbe add-on), as its becoming a new standard that many manufacturers are using for flow analysis. RRD is used for databases and storing of data on a per-host level.

  • Flow-tools is a toolset that can be used to Collect, Send, Process and generate Reports for Netflow data flows and provides an API for developing custom features and applications. Flow Tools is hosted at .
  • Flowscan is more of a visualization tool that analyzes and reports Netflow data and can produce visual graphs that are in near real-time to see whats going on in your network. Flowscan can be deployed on a GNU/Linux or BSD system and uses some of the following packages in order to correctly collect and process flows: cflowd to as the flow collector, flowscan which is a perl script that makes up the software package itself ( FlowScan ) and is responsible for loading and executing reports and the last major component is RRDtool which is used to store all flow information in its database.
  • EHNT (which is pronounced ent ) is an acronym for Extreme Happy NetFlow Tool. This is a commandline tool that supports Netflow Version 5 only and provides reports for intervals between 1 min to 24 hrs and provides information about Ip Protocols, TCP/UDP ports and more.
  • (which stands for Berlekey Packet Filter Traffic collector) is a built on top of the BPF pseudo-device and libpcap for capturing IP traffic, including Source/Destination IP s Ports, number of transmitted/received bytes which are all stored in one compact form binary file.
  • Maji is an implementation of an IPFIX meter which is based on libtrace, a packet capturing and processing library. Maji seems to have an array of information per their website and the latest release was from 07/2011. One of the major benefits to maji is the custom templates you can develop with as many elements included into them as you want, and can be exported via Network over SCTP/TCP/UDP, SQLite database or the terminal.
  • cflowd is a tool that is made for analyzing Netflow enabled devices and includes modules for collecting, storing and analyzing netflow data. Apparently cflowd is no longer being supported per their website, and is directing users to use flow-tools with FlowScan in order to take advantage of cflowd and its modules.
  • AnonTool is more of an anonymization tool for netflow v5 v9 traces.
  • According to the sourceforge page, this project is no longer being developed or supported and was an open-source project that used NetFlow data to help detect and stop (Distributed) Denial of Service attacks. It is no longer support or being updated, so use at your own risk. Check out their Sourceforge page for more information and a download link.
  • pmGraph is a great open source tool for graphing and monitoring bandwidth using pmacct, which is a network monitoring and auditing tool. pmacct collects and monitors traffic using Netflow or Sflow on network devices (including firewalls, routers and switches) into a database and allows for analysis of that data using pmGraph. The software was developed by Aptivate staff and volunteers and looks to still be active.
  • sFlow toolkit is an open source software package the is used for analyzing sFlow data and can be used with other utilities including tcpdump, ntop and Snort for further analysis. sflowtool is the main component of the sFlow toolkit software and is a command-line utility that gives you the ability to view network traffic devices in real-time and interface with other software packages for mapping out graphical images of IP flow. sflowtool is also available for windows as well per their website .
  • NDSAD, which stands for NetUP s Data Stream Accounting Daemon, was developed by NetUP as a tool to capture packets and generate Netflow v5 data streams and was specifically used for ISP billing purposes. The software still seems to be supported as well.
  • NFsen, which is short for N et f low Sen sor, is a web-based front-end tool for nfdump to present the user a nice graphical image of all the data nfdump pumps out. You have the ability to generate reports of your netflow data with information including Flows, Packets and bytes using RRD database tool, as well as setup alerts and view historical data. nfsen project is still very active and can be downloaded from its Sourceforge page here and runs on any Unix/Linux systems. You ll need PHP, PERL (along with Perl Mail::Header and Mail::Internet modules), RRD Tools module and Nfdump tools installed on your system in order to use it correctly.

  • If your not convinced that you ve found any Open Source Netflow Analyzers that will suite your needs, due to either your skill level or understanding of Unix/Linux systems, you can always try one of these Free netflow software packages that we ve recently reviewed that will work for Windows systems.

    Most, if not all those downloads are free and can be setup and used very quickly some of them also offer pro versions of the software that can be had for very little investment. Check them out and let us know what you think.

    New relic for PHP: web application performance monitoring #php #application #performance


    New relic for PHP: web application performance monitoring

    The performance of a web application plays a critical role in how an application is perceived by its users. It is important to measure it, identify the causes if it changes and react swiftly to any unexpected changes. This article describes an industry leading tool, New Relic. and how it can be used to monitor and improve your site performance. Setting up a good web application monitoring system can be tiresome, but it’s well worth it. Without the monitoring tools the only thing we could tell is if our site is performing as expected or not. In order to improve the performance we have to be able to identify the worse performing user actions and profile them independently to pinpoint the cause. New Relic achieves that and more in just a few screens, all without manually adding any profiling code to your application.

    New Relic is a real-time application monitoring service, providing various metrics about the performance of your production site, covering everything from application database queries through to the time it takes for the end-user to view a page. This data is then collected, post-processed and converted to simple and clean charts presented in the New Relic web interface. Since the New Relic agent has to collect and report the data, it does add some overhead to the application stack. Unless you’re running a service that has to respond in a few milliseconds, however, the overhead added is minimal and is far outweighed by the value of the reports enabling you to detect and solve problems early.

    This article covers both the basic functionality of New Relic (that can be used for free) as well as describing what the Enterprise version has to offer.

    Getting started

    The New Relic installation is split into several distinct components:

    • the agent component – a PHP extension, which collects the data and reports to a locally running New Relic daemon.
    • the daemon component, acting as a proxy between the PHP agents and New Relic datacenters. The main responsibility of the daemon is to reduce the time of reporting the data to New Relic.
    • New Relic reporting suite – the main New Relic website, where the data is presented for the user.

    Both the agent and the daemon components are installed using the provided newrelic-install script. The script will detect the available PHP installations and deploy the agent extension to all of them.

    Please refer to the official documentation for more detailed information regarding the installation and configuration of the New Relic package on your specific platform.

    Basic Charts

    To get a glimpse of how your site is performing for different countries, you could look at the worldwide Apdex chart. New Relic also provides more detailed information for the enterprise customers.

    Since the performance problem in this case is usually due to the global network speed, there is no fix that can be applied locally – you’ll need to bring your service closer to the user. Depending on your application needs one or more of the following measures can be employed:

    • use a CDN to serve static files from local servers
    • use local dynamic content caching servers for slower areas
    • implement your service locally for the slower areas

    Entreprise functionality

    “The Total Package!”

    The basic functionality that New Relic offers for free can give us a lot of valuable insights about the global site performance. We can see what areas need more attention than others and this alone can save some precious time while optimising the site. Yet, it does not provide some of the (sometimes crucial) information; where exactly is the bottleneck?

    In addition to the free Lite account New Relic offers two more plans (Standard and Pro) which extend the basic reports and introduce some new ones, allowing you to drill down to the root of performance problems quickly and efficiently.

    Application profile traces

    One of the best features offered to help debug performance problems is the comparison between different web transactions and the ability to see timed application traces of slow calls. New Relic provides charts similar to those described above for each web transaction type (provided that New Relic supports the framework you’re using). Also, a list of slow transaction traces is included with the detailed information.

    There are already several tools available to profile your PHP code, such as Xdebug and XHProf. Xdebug is a really powerful development tool as well as offering profiling capabilities. XHProf is simple to configure and relatively easy to use, and there are also companion tools such as XHGui which make life even easier. So what is different about New Relic?

    The code profiling trace that New Relic provides is a call tree with only Incl. Wall (absolute and relative) information. This tree alone is not very well suited for a generic code analysis since it does not provide the count of how many times a method was invoked, nor its total time during the application run. The power of it is that it is integrated with all other New Relic features and is easily accessible for a quick review once a slower transaction is detected. In addition to PHP code profiling, New Relic also provides a separate report for slow SQL statements, with their execution times and call counts.

    With the help of these integrated traces, finding slower pieces of the application code is a straightforward task, helping to keep the focus on the site as a whole while still being able to detect problems and pinpoint them to the method level.

    Compare with historical data

    In addition to displaying the current state, New Relic also provides a comparison mode. When this mode is turned on, all the basic charts are affected – in addition to the current data they now also provide information from one day and one week ago. This mode is especially useful to show whether the site is performing any better (or worse) than before.


    How well is your website performing under load? The easiest way to answer that is to look at the scalability chart that New Relic provides. The chart plots the application response time versus the throughput.

    This chart can quickly give you an idea about how well your website is responding given that there are a certain number of requests per minute. If the response time is constant as the throughput increases then your site is performing well. However, if you notice that the response time is increasing together with the throughput then it is time to take action. Finding the bottleneck using New Relic should now be an easy task using the database and application code profiling tools described above.

    More information about this chart can be found in the New Relic blog .

    Final thoughts

    New Relic is an amazing service to monitor your web application. It is simple and powerful – all the numbers are presented in such a way that a quick glance to the chart enables one to tell a lot about the site’s performance. In this blog post we have reviewed the common problems that New Relic can help us to detect and provided several suggestions of how to fix them.

    Also, it is probably worthwhile mentioning that while New Relic is very good at what it does, it is a service to monitor your application and it usually works best if combined with a separate system to monitor the server resources or the performance of each service you’re using – understanding how the whole application ecosystem behaves is essential in order to build a stable and well performing web service.

    PRTG for iOS—Access Your PRTG Installation On the Go! # #prtg,


    PRTG for iOS

    This video is gonna carry some new features for the PRTG for iOS application from Paessler.

    The first thing you’ll see when you open up the application is the last view that you had when you have that application open. You can click on a group and then click on a group that is underneath that group in your PRTG installation. You can keep going until you find the host or the device that you want to look at in your PRTG installation and go to a specific sensor. The sensor overview tab will give you an idea of which sensors are green or other status.

    Once you click on a device you’ll be able to see all the sensors for the device. There you’ll be able to see the status as well of all the sensors whether they’re in error status or okay status or warning status.

    This gives you a good overview of how the health is of the actual device in PRTG. When you’re at the sensor overview page you can see the various statistics for the sensor as well as the graphs at the bottom. You can click on the graph on the bottom to actually make this also full screen.

    Some other features on the sensor page are the ability to favor a sensor or to change the priority of it. If your favorite a sensor in this dialog box then when you click on the installation on the selling side you’ll be able to see that right away.

    Some other new features of the app are that you can acknowledge alarms with the acknowledge in text as well as pause sensors that maybe in a false state or being worked on. Something else that can be done through the PRTG for iOS app is looking at the maps that you have in your PRTG installation. You can view at the entire map with your iOS device directly with PRTG for iOS app. Here you can see a map of our monitoring environment here at Paessler.

    With the PRTG for iOS app you can also view reports that you have run before.

    Here we can look at the top most least use bandwidth sensors click on the report and you get directly in the iOS app. If you have a newer iOS device then the new notification feature is quite handy as well. With the new app you can set background and foreground notifications for errors warnings and unusuals and PRTG for iOS will notify you even if it runs the background whenever new alarms are detected.

    You are even able to decide which sensor types you want to have notifications for. If you have an issue with your PRTG installation itself you can also submit a support request directly to our team through the PRTG for iOS application.

    With PRTG for iOS you can even connect to different PRTG severs at the same time to keep track of multiple instances of PRTG. We think that all over Apple mobile device users are going to love this new app and hope that it along with your awesome PRTG software will keep your network running smoothly without any of those a.m. “hey the network crashed” phone calls. We hope that you enjoy the PRTG for iOS that we’ve built for you and hope that helps you on your network more effectively and seamlessly.

    Thanks for your time.

    System Requirements

    iOS version: You need iOS 8 or later to install the app.

    Hardware: We regularly test our PRTG for iOS app on the latest iOS devices. We’re confident that the app will run smoothly on any iOS device.

    PRTG Server: The server you connect to needs to be reachable from the network your device is connected to—either directly or via a VPN connection. The server requires PRTG version 13 or later. If you want to configure push notifications, your PRTG server must run version 14.4.13 or later.

    Note: The app currently does not support PRTG cluster setups! Should you require more detailed information or further assistance, please contact [email protected].

    SQL Server Performance Monitoring through windows performance monitor counters #sql #server


    It seems your question is more related to Windows Performance Monitor Counters definitions, than with SQL Server, other than the fact that you collected counter objects into a SQL database table.

    what counters do i take into consideration.

    That depends on what type of performance condition or issue you are trying to troubleshoot. What exactly is the problem you are trying to solve?

    The types and definitions of Performance Monitor counters vary, depending on which version of Windows you are asking about and what products are installed (ie: Exchange, SQL Server, IIS, etc).

    Here’s what I came up with after a little research:

    svchost.exe is a generic host process name for services that run from dynamic-link libraries.

    HealthService is a database name on this server. svchost is probably some type of internal database used by windows to monitor all svchost processes.

    It appears that Exchange Server may be installed on this machine, is that correct?

    The items listed are the individual performance counter objects, but it would have been useful to see what parent object each are classified under. For example, Memory or Process are both parent performance counters with many instances of object types falling under each.

    You could probably benefit from studying a good overview of Window Performance Monitor . Hope that helps,

    Phil Streiff, MCDBA, MCITP, MCSA
