Logging of TVheadend

DJ Jo

I'm trying to log tvheadend, because of bad reception whit dvb-t.
so i had removed "-f" but when I do that, I see everything and he wants to run it as root?
so a entered


TVH_USER=hts
TVH_DEBUG=1
TVH_CONF_DIR=/home/hts/.hts

but no change, it stil runs it as root.

"> /home/hts/log" does noting

tvheadend logs to syslog, so the extra logging information will go there, I think.

Regarding the -f and the fact that it always runs as root, how are you starting the application? Is this installed from a package, or have you compiled it yourself - and on what OS?

And what file are you editing? This isn't /etc/default/tvheadend, which is where I'd put the TVH_DEBUG=1 statement. I suspect that you may be setting it and then resetting it to 0 if /etc/default/tvheadend still contains TVH_DEBUG=0 (in the# Read configuration variable file if it is present bit)

Sorry, lots of questions, just trying to understand...

Tanks for your anser, i use at the moment:

tail -f /var/log/syslog | grep tvheadend

is there a list of debug explanations form the difference loggings items? so i can filter my logs?
like "epg:" for epg items
"ts:" for transport items

Not that I'm aware of - you could look at the source code to see what's defined, or you'll have to work it out from context in the log.
