Comentários

ASP.NET monitoramento de integridade permite que a equipe de produção e operações gerencie aplicativos Web implantados. O System.Web.Management namespace contém os tipos de eventos de integridade responsáveis por empacotar dados de status de integridade do aplicativo e os tipos de provedor responsáveis por processar esses dados. Ele também contém tipos de suporte que ajudam durante o gerenciamento de eventos de integridade.

A WebBaseEventCollection classe é usada para fornecer uma coleção de eventos de monitoramento de integridade para provedores como o SqlWebEventProvider.
