示例

下面的示例分为两部分。 第一个是配置文件的摘录，使 ASP.NET 能够使用使用该 WebProcessInformation 类型的自定义事件。

第二个演示如何实现自定义事件。

确保自定义事件在适当时间引发，也就是说，当将引发它替换的等效系统运行状况事件时。

注解

ASP.NET 运行状况监视允许生产和运营人员管理已部署的 Web 应用程序。 命名空间 System.Web.Management 包含负责打包应用程序运行状况状态数据的运行状况事件类型和负责处理此数据的提供程序类型。 它还包含有助于管理运行状况事件的支持类型。

类的 WebProcessInformation 实例包含使用派生自 该 WebManagementEvent 类型的任何类型获取的信息。

应用程序需要适当的权限才能访问此类型提供的受保护信息。

以下示例是可用于启用 ASP.NET 以记录包含进程信息的错误事件的配置文件的摘录。

<healthMonitoring   
  enabled="true" heartBeatInterval="0">  

    <rules>  
     <add   
       name="All Errors Default"  
       eventName="All Errors"  
       provider="EventLogProvider"  
       profile="Default"  
       minInterval="00:01:00" />
