WebErrorEvent Class
Provides information about systemic errors.
Assembly: System.Web (in System.Web.dll)
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 WebErrorEvent 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 WebErrorEvent class, see the example provided in this topic. |
The following code example shows how to derive from the WebErrorEvent class to create a custom event.
Also shown is an excerpt of the configuration file that enables ASP.NET to use this custom event.
