Traces - verbose debugging¶

It is quite usuall that a developer asks you to provide more verbose logs using the tracing subsystem which tvheadend includes. If you see --trace <comma_separated_list_of_subsystems> you need to follow this.

The first way to enable traces is from the command-line options (to specify the log file and all subsystems to debug), like:

./build.linux/tvheadend -l /tmp/tvheadend.log --trace htsp,subscription,pat,pmt,bat
