Examples

The following configuration file excerpt shows how to specify a provider of type TraceWebEventProvider in the healthMonitoring section. The add element in the rules section specifies that the provider will handle request-processing events.

<healthMonitoring  
    enabled="true"  
    heartBeatInterval="0">  
    <providers>  
        <add name="TraceEventProvider"  
            type="System.Web.Management.TraceWebEventProvider,   
              System.Web"  
            buffer="false"  
            bufferMode=""  
            maxEventLength="4096"  
            maxSize="4096"  
            maxMessagesPerNotification="1"  
        />  
    </providers>  
    <eventMappings>  
        <add name="Request Processing Events"  
            type="System.Web.Management.WebRequestEvent, System.Web"   
        />  
    </eventMappings>  
    <profiles>  
        <add name="Trace"  
            minInstances="1"  
            maxLimit="Infinite"  
            minInterval="00:00:00"  
        />  
    </profiles>  
    <rules>  
        <add name="Trace Request Processing"  
            eventName="Request Processing Events"  
            provider="TraceEventProvider"  
            profile="Trace"  
        />  
   </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.

This provider passes events to the Trace object. It passes events that derive from the WebBaseErrorEvent class as trace errors and passes all other events as trace information.

Note

The TraceWebEventProvider object does not provide event buffering.

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 creating a custom provider, see How to: Implement the Health Monitoring Custom Provider Example.
