ASP.NET health monitoring 允许生产和运营人员管理已部署的 Web 应用程序。ASP.NET health monitoring allows production and operations staff to manage deployed Web applications. System.Web.Management命名空间包含负责打包应用程序运行状况数据的运行状况事件类型, 以及负责处理此数据的提供程序类型。The System.Web.Management namespace contains the health event types responsible for packaging application health-status data and the provider types responsible for processing this data. 它还包含在运行状况事件的管理过程中可帮助的支持类型。It also contains supporting types that help during the management of health events.

类用于将运行状况监视事件的集合传递给提供程序, 如SqlWebEventProviderWebBaseEventCollectionThe WebBaseEventCollection class is used to deliver a collection of health-monitoring events to providers such as the SqlWebEventProvider.
