Performance counters

Applies To: Windows Server 2008, Windows Server 2008 R2

Windows Media Services provides two sets of performance object counters that you can use to monitor your Windows Media servers and publishing points: Windows Media Services and Windows Media Publishing Points.

On the Monitor tabs of both your server and publishing point, you can click the Performance button to open a performance monitor that reports the most commonly used Windows Media performance counters for the selected object. You can add or remove counters from the monitor to suit your needs.

Windows Media performance counters can provide useful information in the following scenarios:

  • Real-time usage statistics. Performance counters provide information about the current usage of the server, such as the number of currently connected Players, the amount of bandwidth utilization, and the number of distribution streams.

  • Identify streaming problems. Performance counters can provide information to help you identify and troubleshoot issues in your streaming system, such as the number of stream errors and resend requests.

  • Monitor encoder and distribution streams. Encoder and distribution server packet counters help identify when streams from an encoder or streams through a distribution server are failing.

  • Report peak usage. Most counters provide peak values, which enable you to track the maximum capacity of your system.


Windows Media Services 2008 includes a built-in cache/proxy plug-in. In the performance monitor Add Counters dialog box, you will see the following additional publishing point instances: Cache/Proxy Broadcast and Cache/Proxy On-Demand. These publishing points are only active if you have enabled the WMS Cache/Proxy plug-in. For more information, see Caching and Proxying Content with Windows Media Services 2008.
