WebProcessStatistics 类

定义

为评估运行进程的状况提供信息。

public ref class WebProcessStatistics
public class WebProcessStatistics
type WebProcessStatistics = class
Public Class WebProcessStatistics
继承
WebProcessStatistics

示例

下面的代码示例有两个部分。 第一个是配置文件的摘录,使 ASP.NET 能够使用使用该WebProcessStatistics类型的自定义事件。 第二个说明如何实现此自定义事件。

确保自定义事件在适当的时间引发,也就是说,当引发等效的系统运行状况事件时,将引发该事件。

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。 它还包含支持类型,这些类型有助于管理运行状况事件。

类的 WebProcessStatistics 实例包含使用 WebHeartbeatEvent 类型获取的信息。

备注

在大多数情况下,可以使用实现的 ASP.NET 运行状况监视类型,并通过在healthMonitoring配置部分中指定值来控制运行状况监视系统。 还可以从运行状况监视类型派生,以创建自己的自定义事件和提供程序。 有关创建自定义事件类的示例,请参阅本主题中提供的示例。

下面是可用于启用 ASP.NET 记录包含进程统计信息的检测信号事件的配置文件摘录。
