ASP.NET health monitoring allows production and operations staff to manage deployed Web applications. 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. It also contains supporting types that help during the management of health events.
The WebBaseEventCollection class is used to deliver a collection of health-monitoring events to providers such as the SqlWebEventProvider.
The following code example shows how to use the WebBaseEventCollection class.
Imports System Imports System.Text Imports System.Web Imports System.Web.Management Imports System.Collections ' Implements a custom WebBaseEvent class. ' Everytime this class is instantiated a WebBaseEvent is ' created. This event object is then added to the static ' simulatedEvents array list.
