Exemplos

O exemplo de código a seguir tem duas partes. A primeira parte é um trecho do arquivo de configuração que permite que ASP.NET usem um evento personalizado. O segundo mostra como criar esse evento personalizado usando a WebApplicationInformation classe .

Verifique se o evento personalizado é gerado no momento adequado, ou seja, quando o evento de integridade do sistema equivalente que ele substitui for gerado.

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 evento 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.

As instâncias da WebApplicationInformation classe contêm informações obtidas usando qualquer um dos tipos derivados do WebManagementEvent tipo .

Seu aplicativo precisa das permissões apropriadas para acessar informações protegidas fornecidas por esse tipo.

Veja a seguir um trecho de um arquivo de configuração que você pode usar para habilitar ASP.NET registrar eventos de erro que contêm informações do aplicativo.
