Monitoring Web Applications with Microsoft Monitoring Agent

Updated: November 1, 2013

Applies To: System Center 2012 R2 Operations Manager

When Microsoft Monitoring agent is used together with System Center Operations Manager, it adds value for IT Operations by providing real-time alerting, operational reporting, and centralized management of configuration. Microsoft Monitoring Agent without connection to System Center can be used as a lightweight Application Performance Monitoring (APM) solution for Microsoft .NET Framework applications that does not require heavy infrastructure from IT Operations, so you can begin monitoring applications within a few minutes.

You can download Microsoft Monitoring Agent for stand-alone use or for use with Operations Manager from the Microsoft Download Center. You can also install it from the System Center 2012 R2 Operations Manager media. Downloading Microsoft Monitoring Agent from the Download Center gives you the latest version of the agent with the latest monitoring capabilities. After you install Microsoft Monitoring Agent for use without Operations Manager, you can use it to collect application traces locally. Microsoft Monitoring Agent adds the following new Windows PowerShell commands that control local monitoring:

  • Start-WebApplicationMonitoring starts monitoring an Internet Information Services (IIS) web application.

  • Stop-WebApplicationMonitoring stops monitoring an IIS web application and creates a Microsoft IntelliTrace file by using data that is collected during monitoring.

  • Checkpoint-WebApplicationMonitoring creates a snapshot of the IntelliTrace file and continues monitoring.

  • Get-WebApplicationMonitoringStatus gets the monitoring status of all monitored web applications.

Monitoring by Using Local Collection

To start and stop monitoring by using local collection

  1. Start Windows PowerShell as an administrator. Your account must be a member of the Local Administrators group to perform this task, or you must run Windows PowerShell as a user who belongs to the Local Administrators group.

  2. If you are using Windows PowerShell 2.0, you must manually import the monitoring module Microsoft.MonitoringAgent.PowerShell.dll from the Microsoft Monitoring Agent installation location. By default, the module is located at C:\Program Files\Microsoft Monitoring Agent\Agent\PowerShell\Microsoft.MonitoringAgent.PowerShell\. For example, to import the module, at the Windows PowerShell command prompt, type import-module "C:\Program Files\Microsoft Monitoring Agent\Agent\PowerShell\Microsoft.MonitoringAgent.PowerShell\Microsoft.MonitoringAgent.PowerShell.dll".

    ImportantImportant
    If you are using Windows PowerShell 2.0 and close Windows PowerShell, you must repeat this step to use any Windows PowerShell commands in Microsoft Monitoring Agent.

    If you are using Windows PowerShell 3.0, the module will already be imported and you do not need to import it manually as described in this step.

  3. At the Windows PowerShell command prompt, type Start-WebApplicationMonitoring and then specify the web application name, the monitoring mode, and the output location. For example, type Start-WebApplicationMonitoring Fabrikam/FabrikanFiber.Web Monitor c:\outputlogs.

    • To find the web application name, use the Get-WebSite and Get-WebApplication Windows PowerShell commands.

    • To limit the amount of space that is allocated for traces, use the MaximumFileSizeInMegabytes parameter and allocate enough space.

    • The monitoring mode can be Trace, Monitor, or Custom. These monitoring modes use a collection plan, which determines how an application is monitored (such as custom namespaces to monitor, all or only critical exceptions, and application-specific exception handlers). When you use Trace, you can use Microsoft Monitoring Agent in the same way that you might have used an IntelliTrace collector, and you can use collection plans in the form of the IntelliTrace collector that was part of Microsoft Visual Studio 2010 and Visual Studio 2012 and is available in Visual Studio 2013. The Monitor option uses the default monitoring collection plan that is preconfigured with Microsoft Monitoring Agent. The default collection plan is located in the same folder as the monitoring module. You can use this default collection plan by using the Monitor option, or you can copy it to a different file and customize it and use it with the Custom monitoring mode.

    WarningWarning
    Starting and stopping monitoring might restart or recycle your application IIS pool.

  4. To stop monitoring, type Stop-WebApplicationMonitoring. For example, type Stop-WebApplicationMonitoring Fabrikam\FabrikamFiber.Web. For more information about using Windows PowerShell commands, see these Windows PowerShell topics: Microsoft.MonitoringAgent.PowerShell.Start-WebApplicationMonitoring, Microsoft.MonitoringAgent.PowerShell.Stop-WebApplicationMonitoring, Microsoft.MonitoringAgent.PowerShell.Checkpoint-WebApplicationMonitoring, Microsoft.MonitoringAgent.PowerShell.Get-WebApplicationMonitoringStatus.

Using Local Monitoring and the .NET APM Template in System Center at the Same Time

If you configured application monitoring by using the .NET Application Performance Monitoring template in Operations Manager, you can still use Windows PowerShell commands in Microsoft Monitoring Agent local monitoring to monitor applications. The Windows PowerShell commands in Microsoft Monitoring Agent have higher priority than the APM monitoring configuration and will temporarily override the APM monitoring configuration when you use them to start local collection. For more information, see Microsoft Monitoring Agent Requirements and Compatibility.

Customizing Local Collection

To get useful results from your monitoring, you might need to customize default collection settings, such as namespaces and thresholds that specify your application-specific service level agreements (SLAs). This customization is controlled in your collection plan. After you edit the collection plan, you must restart monitoring.
