Constructors

	Name	Description
	WebErrorEvent(String, Object, Int32, Exception)	This API supports the product infrastructure and is not intended to be used directly from your code. Initializes the WebErrorEvent class using the supplied parameters.
	WebErrorEvent(String, Object, Int32, Int32, Exception)	This API supports the product infrastructure and is not intended to be used directly from your code. Initializes a new instance of the WebErrorEvent class using the supplied parameters.

Properties

	Name	Description
	ErrorException	Gets the Exception associated with the error. (Inherited from WebBaseErrorEvent.)
	EventCode	Gets the code value associated with the event.(Inherited from WebBaseEvent.)
	EventDetailCode	Gets the event detail code.(Inherited from WebBaseEvent.)
	EventID	Gets the identifier associated with the event.(Inherited from WebBaseEvent.)
	EventOccurrence	Gets a counter that represents the number of times the event has occurred.(Inherited from WebBaseEvent.)
	EventSequence	Gets the number of times the event has been raised by the application.(Inherited from WebBaseEvent.)
	EventSource	Gets the object that raises the event.(Inherited from WebBaseEvent.)
	EventTime	Gets the time when the event was raised.(Inherited from WebBaseEvent.)
	EventTimeUtc	Gets the time when the event was raised.(Inherited from WebBaseEvent.)
	Message	Gets the message that describes the event.(Inherited from WebBaseEvent.)
	ProcessInformation	Gets information about the ASP.NET application-hosting process.(Inherited from WebManagementEvent.)
	RequestInformation	Gets the application request information.
	ThreadInformation	Gets the application-thread information.

Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	FormatCustomEventDetails(WebEventFormatter)	Provides standard formatting of the event information.(Inherited from WebBaseEvent.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	IncrementPerfCounters()	This API supports the product infrastructure and is not intended to be used directly from your code. Used internally to increment performance counters.(Overrides WebBaseErrorEvent.IncrementPerfCounters().)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	Raise()	Raises an event by notifying any configured provider that the event has occurred.(Inherited from WebBaseEvent.)
	ToString()	Formats event information for display purposes.(Inherited from WebBaseEvent.)
	ToString(Boolean, Boolean)	Formats event information for display purposes.(Inherited from WebBaseEvent.)

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.

The WebErrorEvent provides information about errors caused by problems with configuration or application code. An example is the error issued by ASP.NET when an error is found in a page.

Note
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 deriving from the WebErrorEvent class, see the example provided in this topic.

Examples

The following code example shows how to derive from the WebErrorEvent class to create a custom event.

Also shown is an excerpt of the configuration file that enables ASP.NET to use this custom event.

<healthMonitoring 
  enabled="true" heartBeatInterval="0">

  <eventMappings>

    <add  name="SampleWebErrorEvent" type="SamplesAspNet.SampleWebErrorEvent,weberrorevent,Version=1.0.1573.21549, Culture=neutral, PublicKeyToken=2a0b23915ac7352b, processorArchitecture=MSIL"/>

  </eventMappings>

  <profiles>
    <add name="Custom"
      minInstances="1"
      maxLimit="Infinite"
      minInterval="00:00:00" />
  </profiles>

  <rules>
    <clear />

    <add name="Custom Web Error Event" 
      eventName="SampleWebErrorEvent"
      provider="EventLogProvider" 
      profile="Custom" />
  </rules>

</healthMonitoring>
