Log Types
Windows Media Services supports both client logs and server logs. Client logs generally send client information upstream from a Windows Media Player, or a player built upon the Windows Media Format SDK, to the origin server. However, if the player is receiving a multicast, the log can be submitted to an alternate server (typically a Web server). Furthermore, if a player is rendering an ASX file that contains a LogURL tag, the player submits client logs to both the streaming server and the URL specified in the LogURL tag. Client logs are further subdivided into client render logs, client receive logs, and combination (legacy) logs. Traditionally, clients have sent combination logs because they receive and render simultaneously. With the advent of fast caching in Windows Media Services 9 Series, however, content can be delivered to the client at rates that exceed real time, and the client can finish receiving the content before it has finished rendering it. Windows Media Services 9 Series also supports server logs that provide information about distribution servers and cache proxy servers.
