Transaction Logs
The SE’s transaction logging format for Windows Media streaming is consistent with that of the
Windows Media Services and the World Wide Web Consortium (W3C)-compliant log format. A log line
is written for every stream accessed by the client. The location of the log is not configurable. These logs
can be exported using FTP. When transaction logging is enabled, daemons create a separate working.log
file in /local1/logs/export for WMT transactions.
All client information in the transaction logs is sent to the origin server by default.
Note All WMT playable contents can be delivered by either HTTP or RTSP, based on the request. Any content
that is cached by the WMT is stored using the RTSP scheme, regardless of whether the content was
cached due to an HTTP or RTSP request. Therefore, in the show command, the content displays as RTSP.
Log Formats Accepted by Windows Media Services 9
Windows Media Players connect to a Windows Media server using the following protocols:
• Windows Media Players earlier than Version 9.0 use HTTP/1.0 or the MMS protocol.
• Windows Media Player Version 9.0 uses HTTP/1.1 and RTSP.
Depending on the version of the Windows Media Player, logs are sent in different formats, such as text,
binary, or Extensible Markup Language (XML). Table 7-27 describes the log formats accepted by
Windows Media Services Version 9.0.
Note Extensible Markup Language (XML) logging for MMS-over-HTTP and MMS-over-RTSP (RTSP over
Windows Media Services Version 9.0) is supported. The posted XML log file from the Windows Media
Player to the SE (Windows Media server) can be parsed and saved to the normal Windows Media
transaction logs that are stored on the SE.
