Expanded Event Monitoring

Expanded Event Monitoring

In this version of Windows Media Services, event access has been redesigned, the number of available events increased, and the information contained in each event expanded.

You can use interfaces provided by the Windows Media Services SDK to receive event notifications for server, publishing point, limit change, limit hit, plug-in, and playlist events.

You can also use Windows Management Instrumentation (WMI) to receive the same event notices externally. WMI provides a generic way to manipulate objects locally and remotely using a single, extensible, object-oriented interface. You can query for events for virtually any change in the managed objects and, through the flexible WMI architecture, define what action, if any, to take when an event is received. The WMS WMI Event Handler Plug-in enables Windows Media Services to generate WMI events. It registers itself as an event provider with WMI.

The WMS Active Script Handler Plug-in enables you to write a script that can act as an event notification and authorization plug-in. Any scripting language that supports Microsoft Active Scripting technology, such as Microsoft JScript®, Microsoft Visual Basic® Scripting Edition, or Perl, can be used. For example, you can customize the server response to internal events, authorization events, or basic plug-in actions such as enabling or disabling a plug-in.

You can also create your own event notification plug-in. For more information, see Creating Event Notification Plug-ins.
