WmiWebEventProvider Class

Implements an event provider that maps ASP.NET health-monitoring events to Windows Management Instrumentation (WMI) events.

Namespace:  System.Web.Management
Assembly:  System.Web (in System.Web.dll)

[AspNetHostingPermissionAttribute(SecurityAction::InheritanceDemand, Level = AspNetHostingPermissionLevel::Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)]
public ref class WmiWebEventProvider : public WebEventProvider

ASP.NET health monitoring allows production and operations staff to manage deployed Web applications. The System.Web.Management namespace contains the health-event types responsible for packaging application health-status data and the provider types responsible for processing this data. It also contains supporting types that help during the management of health events.

ASP.NET uses this class to map health-monitoring events to WMI events. To enable the delivery of ASP.NET health-monitoring events to the WMI subsystem, you must configure the WmiWebEventProvider class by adding the appropriate settings in the <healthMonitoring> section of the configuration file.

The information contained in the Aspnet.mof file describes the parameters of the WMI events raised when ASP.NET health-monitoring events are routed to the WmiWebEventProvider class and mapped into WMI events. The Aspnet.mof file is stored in the .NET Framework build directory, for example %windir%\Microsoft.NET\Framework\BuildNumber. For more information about reporting health-monitoring events as WMI events, see Using WMI to Deliver ASP.NET Health-Monitoring Events.

NoteNote:

In most cases you will be able to use the ASP.NET health-monitoring types as implemented, and you will control the health-monitoring system by specifying values in the <healthMonitoring> configuration section. You can also derive from the health-monitoring types to create your own custom events and providers. For an example of creating a custom provider, see How to: Implement the Health Monitoring Custom Provider Example.

The following example shows how to create a consumer of WMI events issued by ASP.NET health monitoring as a result of Web-application health events.

NoteNote:

The WmiWebEventProvider class and the health event types to monitor are already configured by default. The only thing you need to do is to define the rule for all the health events. Remember that the health events are not dispatched to the WmiWebEventProvider provider by default.

No code example is currently available or this language may not be supported.

The following example is a configuration file excerpt that shows a <healthMonitoring> configuration section that enables ASP.NET to use the WmiWebEventProvider provider to process all health-monitoring events.

<healthMonitoring>
  <rules>
    <add 
      name="Using Wmi"
      eventName="All Events" 
      provider="WmiWebEventProvider" 
      profile="Critical"/>
  </rules>
</healthMonitoring>
