If you have multiple backends, <code>which_recorder.pl</code> will only show information about shows recorded on the backend that runs the script (or, technically, only shows information about shows described in the log file specified, so you could have a slave push its log file to the master occasionally and run the script twice--once for each log file--but that's an exercise left for the reader).

Important.png Note: The correct title of this article is which_recorder.pl. It appears incorrectly here due to technical restrictions.


Author Michael T. Dean
Description Parses the backend log file and outputs information on which capture card was used to record shows, formatted for inclusion in the backend status page.
Supports Version21.png  Version22.png  Version23.png  Version24.png  


which_recorder.pl parses the master backend log file and outputs information on which capture card was used to record shows, formatted for inclusion in the backend status page.

Usage

which_recorder.pl /path/to/master/backend/log/file

Because which_recorder.pl displays information about all recordings in your log file, you'll probably want to rotate your log files occasionally.

If you have multiple backends, which_recorder.pl must be run against the master backend log file. The master backend must be run with a verbose level that includes the "general" verbose messages (which is part of the default verbosity).

To output the information to the console, rather than use it in the Miscellaneous Status Info section of the backend status page, you may call the script with the --text argument.

 which_recorder.pl --text /path/to/master/backend/log/file
