Traces - verbose debugging¶
Please, read this whole information. If you don't see [TRACE] lines in the log file, you misconfigured something and we will ask you for new feedback which slows down the help process.
It is quite usual that a developer asks you to provide more verbose logs using the trace (verbose logs for development) which tvheadend includes. If you see --trace <comma_separated_list_of_subsystems> you need to follow this.
Compile tvheadend using --enable-trace option for the configure script see Building to compile tvheadend directly from sources. The traces are enabled by default, but packages - except debug versions - disable this functionality.
!!! The [TRACE] lines are written only to the log file. You will not see them on console or syslog output. Please, enter the log file. !!!
Command-line¶
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
Web UI¶
The second way is to use the debugging tab in the configuration (this settings is not preserved):
Example¶
You should see [ TRACE] lines in your log file (these lines are not in syslog file or journal)!
