Re: Log files to determine BW usage

And in the case of streaming clients the time a stream is requested gets logged, but I don't see any indication that the connection was successful, or when the client gave up & went away before the streamed file finished.

c-status entry for each client denotes the state of that connection attempt. For example 200 means the connection was successful.


x-duration denotes the duration in seconds of the client session.

The StreamingAdminServer seems to be able to parse this info (& more) to display the number of concurrent connections (for b/w measure), total connections served (hits) and total bytes served (load), but I don't see in the logs how to determine how many bytes were served to any particular user.

The x-duration notes this for each client connection.

Maybe I'm not looking in the right place?

The QTSS/DSS logs record an massive amount of useful information (roughly 32 valuable parameters) which can be used in combination with some basic math to come up with many other valuable results. For example take the total file size of the requested media (as noted by the 'filesize' parameter) combined with the number of bytes sent to the client (as noted by the 'cs-bytes' parameter) to find out what percent of the file was viewed during that session.


Try this KBase article for more info on the log format:

Hope that helps.
