Thetype exposes the following members.
|WebErrorEvent(String, Object, Int32, Exception)||Infrastructure. Initializes the class using the supplied parameters.|
|WebErrorEvent(String, Object, Int32, Int32, Exception)||Infrastructure. Initializes a new instance of the class using the supplied parameters.|
|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.)|

|FormatCustomEventDetails||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||Infrastructure. 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(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 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.
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 class, see the example provided in this topic.
The following code example shows how to derive from the class to create a custom event.
Also shown is an excerpt of the configuration file that enables ASP.NET to use this custom event.
