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

type WebThreadInformation =  class end

The WebThreadInformation type exposes the following members.

Public propertyIsImpersonatingGets the current thread-impersonation mode.
Public propertyStackTraceGets the current thread-managed stack trace.
Public propertyThreadAccountNameGets the thread account name.
Public propertyThreadIDGets the current thread identifier.

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodFormatToStringFormats thread-related information.
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

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.

Instances of the WebThreadInformation class contain information that is obtained using either the WebErrorEvent type or the WebRequestErrorEvent type.

Your application needs the appropriate permissions to access protected information provided by this type.


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 event class, see the example provided in this topic.

The following code example has two parts. The first is an excerpt of a configuration file that enables ASP.NET to use a custom event that uses the WebThreadInformation type. The second shows how to implement the custom event that uses the WebThreadInformation type.

Ensure that your custom event is raised at the proper time, that is, when the equivalent system health event it replaces would be raised.
