WMS WMI Event Handler - general properties

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 the Select All or Clear All buttons.

Windows Media Services and other programs use these events to respond to activity on your server. 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. For more information about event classes and creating custom event handlers, see the Windows Media Services Software Development Kit (SDK). You can configure the following options 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.
Playlist	Select this check box to report events that are invoked by activity related to broadcast playlists.
Cache	Select this check box to report events that are invoked by activity related to caching content, such as a cache hit or cache miss.
Publishing point	Select this check box to report events that are invoked when the status of a publishing point changes or when a change is made to the plug-in properties.
Plug-in	Select this check box to report events that are invoked by any activity related to server or publishing point plug-ins.

Note Image Notes

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.
In many streaming media scenarios, client events can accumulate rapidly. If you select the Client check box to report client events, the large volume of client events may obscure other, more serious events. Because of this, the Client check box is disabled by default.
