Streaming Media Services 2008
This SAM application monitor template assesses the overall health of Streaming Media Services 2008 services and counters. It is recommended to use this template in conjunction with the Windows Server 2003-2008 Services and Counters template.
Prerequisites
RPC and WMI access to the domain controller.
Credentials
Windows Administrator on the domain controller.
Component monitors
Components without predetermined threshold values provide guidance such as "Use the lowest threshold possible" or "Use the highest threshold possible" to help you find a threshold appropriate for your application.
Current Cache Downloads
The number of concurrent streams being downloaded to the memory area of the cache/proxy server.
Current Connected Players
The current number of players with unicast connections to the server. This number does not include distribution server connections.
Current Connection Queue Length
The current number of connection requests that are pending on the server from both player and distribution servers. This value should be as low as possible.
Current Connection Rate
The current number of clients per second that are connecting to the server.
Current File Read Rate (Kbps)
The current rate, in kilobits per second (Kbps), at which data packets are read from a file.
Current Incoming Bandwidth (Kbps)
The current bandwidth, in Kbps, allocated for streams from other servers.
Current Late Read Rate
The current number of data packets per second that take longer than 400 milliseconds to read from the file system.
The value for this monitor should not be higher than zero for an extended period of time. If it is, this may indicate that the WMS server is not able to read from its data sources fast enough.
Current Late Send Rate
The current number of packets that are sent out 0.5 seconds, or more, after the marked send time.
Current Outgoing Distribution Allocated Bandwidth (Kbps)
The current bandwidth, in Kbps, allocated for streams to distribution servers.
Current Outgoing Distribution Connections
The current number of distribution servers that are connected to the server.
Current Outgoing Distribution Send Rate (Kbps)
The current rate, in Kbps, at which data packets are being streamed to distribution servers.
Current Player Allocated Bandwidth (Kbps)
The current amount of bandwidth, in Kbps, that is allocated for all streams to players.
Current Player Send Rate (Kbps)
The current rate, in Kbps, at which data packets are being streamed to players.
If the send rate continuously drops below the allocated bandwidth, WMS will be unable to service all the clients. This may indicate an outbound network bottleneck.
Current Stream Error Rate
The current number of errors per second due to dropped packets.
If this value is higher than zero for an extended period of time, this may indicate that the WMS server is unable to keep up with the demand. This also may indicate late reads.
Current Streaming HTTP Players
The current number of players that are being streamed through the HTTP protocol. This does not include players that are stopped or paused.
Current Streaming MMS Players
The current number of players that are being streamed through the MMS protocol. This does not include players that are stopped or paused.
Current Streaming Players
The current number of players that are being streamed across all protocols. This does not include players that are stopped or paused.
Current Streaming RTSP Players
The current number of players streamed through the RTSP protocol. This does not include players that are stopped or paused.
Current Streaming UDP Players
The current number of players that are being streamed through the UDP transport protocol. This does not include players that are stopped or paused.
Current UDP Resend Requests Rate
The current number of requests for UDP resends per second received from clients.
Current UDP Resends Sent Rate
The current number of UDP resends per second that are sent to clients.
Service: Windows Media Services
Indicates the status of services so you can manage delivery of live or on-demand digital media content, including Windows Media Audio (WMA) and Windows Media Video (WMV), over networks by using administrative interfaces in Microsoft Windows Media Services 2008.
Total Advertisements
The total number of advertisements that were streamed from playlists since the last time the counter was reset.
Total Connected Players
This counter returns the total number of players that have connected to the server since the last time the counter was reset.
Total Late Reads
This counter returns the total number of times that the server required more than 400 milliseconds to read data from the file system since the last time the counter was reset.
Total Late Sends
This counter returns the total number of times the server sent out data packets, 0.5 seconds or more after the marked send time since the last time the counter was reset.
Total Outgoing Distribution Connections
This counter returns the total number of distribution servers that have connected to the server or publishing point since the last time the counter was reset.
Total Server Uptime (s)
This counter returns the elapsed time, in seconds, that the Windows Media Services service has been running since it was last started.
Total Stream Denials
This counter returns the total number of times the server refused to send a requested stream to a client since the last time the counter was reset. This includes denials that occurred due to authorization/authentication failure as well as denials that occurred because limits were exceeded.
Total Stream Errors
This counter returns the total number of stream errors due to dropped packets since the last time the counter was reset.
Total Streaming HTTP Players
This counter returns the total number of players that have streamed data through the HTTP protocol since the last time the counter was reset.
Total Streaming Players
This counter returns the total number of players that have streamed data since the last time the counter was reset.
Total Streaming RTSP Players
This counter returns the total number of players that have streamed data through the RTSP protocol since the last time the counter was reset.
Total Streaming UDP Players
This counter returns the total number of players that have streamed data through the UDP transport protocol since the last time the counter was reset.
