The WebRequestErrorEvent is raised if an error occurs during a Web request. Your application should use this event to obtain request-related information as defined by the WebRequestInformation and the WebThreadInformation classes.

NoteNote

In most cases you will use the standard ASP.NET health monitoring types and control their behavior by setting the healthMonitoring configuration section. You can also create custom types, as shown in the next example. If you create your custom event type and you need to add your own information, customize the FormatCustomEventDetails method, this will avoid overwriting or tampering with sensitive system information.

The following code example has two parts. The first part is an excerpt of a configuration file that enables ASP.NET to use a custom event. The second part shows how to derive from the WebRequestErrorEvent class to create the custom event.

<healthMonitoring enabled="true" heartBeatInterval="0">
  <eventMappings>
    <add  name="SampleWebRequestErrorEvent" type="SamplesAspNet.SampleWebRequestErrorEvent,webrequesterrorevent,Version=1.0.1573.21654, Culture=neutral, PublicKeyToken=63ada862a6c5af13, processorArchitecture=MSIL"/>
  </eventMappings>
  
  <rules>
    <add 
      name="Custom Web Request Error Events"
      eventName="SampleWebRequestErrorEvent" 
      provider="EventLogProvider"  
      profile="Critical"/>
  </rules>
</healthMonitoring>
