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.
Instances of the WebApplicationInformation class contain information that is obtained using any of the types derived from the WebManagementEvent type.
Your application needs the appropriate permissions to access protected information provided by this type.
The following is an excerpt of a configuration file you could use to enable ASP.NET to log error events that contain application information.
<healthMonitoring
enabled="true" heartBeatInterval="0">
<rules>
<add
name="All Errors Default"
eventName="All Errors"
provider="EventLogProvider"
profile="Default"
minInterval="00:01:00" />
</rules>
</healthMonitoring>
 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 event class, see the example provided in this topic. |
The following code example has two parts. The first part is an excerpt of the configuration file that enables ASP.NET to use a custom event. The second shows how to create that custom event by using the WebApplicationInformation class.
Ensure that your custom event is raised at the proper time, that is, when the equivalent system health event it replaces would be raised.
<healthMonitoring
enabled="true" heartBeatInterval="0">
<eventMappings>
<add name="SampleApplicationInformation"
type="SamplesAspNet.SampleWebApplicationInformation, webapplicationinformation, Version=1.0.1585.27289, Culture=neutral, PublicKeyToken=3648e5c763a8239f, processorArchitecture=MSIL"/>
</eventMappings>
<rules>
<add name="Custom Application Information"
eventName="SampleApplicationInformation"
provider="EventLogProvider"
profile="Default"/>
</rules>
</healthMonitoring>
