Assembly: System.Web (in system.web.dll)
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 WebBaseErrorEvent class is the base class for the health-monitoring events that represent error conditions. ASP.NET uses WebBaseErrorEvent and its derived types to indicate error conditions during the lifetime of a Web application.
In most cases you will be able to use the ASP.NET health-monitoring types as implemented and you will control the health-monitoring system by specifying values in the healthMonitoring configuration section. You can also derive from the health-monitoring types to create your own custom events and providers. For an example of deriving from the WebBaseErrorEvent class, see the example provided in this topic.
The following code example has two parts. The first is an excerpt of a configuration file that enables ASP.NET health monitoring to use an event derived from the WebBaseErrorEvent class. The second shows how to derive from the WebBaseErrorEvent class to create the custom event.
<healthMonitoring enabled="true" heartBeatInterval="0"> <providers> <!-- Define the custom provider that processes custom Web request events. --> <add name="SampleWebEventProvider" type="SamplesAspNet.SampleEventProvider, webeventprovider,Version=1.0.1573.18094, Culture=neutral, PublicKeyToken=b5a57a9a9d487cf4, processorArchitecture=MSIL"/> </providers> <eventMappings> <!-- Define the event source that issues custom events. --> <add name="SampleWebBaseErrorEvent" type="SamplesAspNet.SampleWebBaseErrorEvent, webbaseerrorevent,Version=1.0.1573.21549, Culture=neutral, PublicKeyToken=2a0b23915ac7352b, processorArchitecture=MSIL"/> </eventMappings> <rules> <!-- Associate custom event with related custom provider --> <add name="Custom Web Base Errors" eventName="SampleWebBaseErrorEvent" provider="SampleWebEventProvider" profile="Custom"/> </rules> </healthMonitoring>
The following code shows how to derive from the WebBaseErrorEvent class to create a custom event.
