Examples

The following is an excerpt of a configuration file showing how to configure the EventLogWebEventProvider to capture view-state failures. For completeness we are showing the setup for the provider and eventMappings sections. They are already set by default. The only thing you need to do is to provide the setup for the rules section. Refer to healthMonitoring for more information.

To generate a view-state error, enter a URL in your browser with the following query string:

?__VIEWSTATEFIELDCOUNT=1&__VIEWSTATE=bogus

The Windows Application Eventlog will capture a view-state failure, if you enter the following configuration settings.

<healthMonitoring  
  enabled="true"  
  heartBeatInterval="0">  
  <providers>  
    // Configure the provider to process   
    // the health events.  
    <add name="EventLogProvider"  
       type="System.Web.Management.EventLogWebEventProvider,  
       System.Web,Version=2.0.3600.0,Culture=neutral,  
       PublicKeyToken=b03f5f7f11d50a3a"/>  
  </providers>  

  <eventMappings>  
    <clear />  
    // Configure the WebFailureAuditEvent   
    // object to handle the Viewstate failures.   
    <add name="Failure Audits"  
      type="System.Web.Management.WebFailureAuditEvent,  
      System.Web,Version=2.0.3600.0,Culture=neutral,  
      PublicKeyToken=b03f5f7f11d50a3a" />  
  </eventMappings>  

  <rules>  
    <clear/>  
    // Configure the connection between the   
    // application lifetime event object   
    // and the provider that must process it.  
      <add name="Viewstate Failure Events "  
        eventName="Failure Events"  
        provider="EventLogProvider"  
        profile="Default"  
        minInterval="00:01:00" />  
  </rules>  
</healthMonitoring>

Remarks

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 raises events of type WebViewStateFailureAuditEvent when a view-state failure occurs. This failure indicates either an attempt to tamper with view state or its reuse from another machine with a different key. The related audit event code is AuditInvalidViewStateFailure.

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.
