WMS WMI Event Handler
The WMI Event Handler plug-in controls which Windows Management Instrumentation (WMI) events Windows Media Services reports. You can select which events to report individually or by clicking either Select All or Clear All. You can configure the following options on the General tab for this plug-in.
| Item | Description |
|---|---|
Server |
Select this check box to report events that are invoked when the status of the server changes or when a change is made to the server properties. |
Client |
Select this check box to report events that are invoked when a client connects or disconnects to the server or changes the mode of playback; for example, when the user fast–forwards or stops a digital media file. |
Limit |
Select this check box to report events that are invoked when the limits of a publishing point or server are modified or reached. |

Plug-in |
Select this check box to report events that are invoked by any activity related to server or publishing point plug-ins. |
Note
This plug-in is responsible for communicating event information between the Windows Media Services service and other services and programs. Changing the reported events can cause issues with client programs, including the Windows Media Services snap-in and the Windows Media Services Administrator for the Web.
Note
Because of the large number and high frequency of client events, the event handler does not report them by default. If you choose to report client events, carefully monitor the performance of your server to make sure that its processor is not overloaded.
Note
For more information about event classes and creating custom event handlers, see the Windows Media Services SDK.
