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
