Comentarios

ASP.NET supervisión del estado permite al personal de producción y operaciones administrar las aplicaciones web implementadas. El System.Web.Management espacio de nombres contiene los tipos de eventos de mantenimiento responsables de empaquetar los datos de estado de mantenimiento de la aplicación y los tipos de proveedor responsables de procesar estos datos. También contiene tipos auxiliares que ayudan durante la administración de eventos de mantenimiento.

WebManagementEvent es la clase base para todos los ASP.NET tipos de eventos de supervisión de estado. Usa la WebProcessInformation clase para obtener información de proceso que está disponible para sus clases derivadas.

Notas a los desarrolladores de herederos

Al dar formato a la información de eventos personalizada para mostrar, invalide el FormatCustomEventDetails(WebEventFormatter) método en lugar del ToString método . Esto evitará sobrescribir o alterar la información confidencial del sistema.

El código de evento que especifique para el evento personalizado debe ser mayor que WebExtendedBase.
