Some days ago I mentioned that there were no new entries in openhab.log and event log…

Today I tried to fix this without success, because I don’t know what this means…

openhab> log:list and log:get gives me the follwig output

openhab> log:list    and log:get  gives me the follwig output

Thanks in advance for a helpful suggestion

Today I did go back to 3.2.0.M2
But i have no idea how to fix this problem

When I type log:list
or
log:tail
always the response is : Error executing command: Unrecognized configuration

When last did the logging work - any changes that may have caused the logging to break?

Did you upgrade from <3.0?

Can you share (/userdata/etc):

log4j2.xml
org.ops4j.pax.logging.cfg

Paul_Vennhaus · November 1, 2021, 10:34am

Thank you Mark, because of your questions I made one step forward !

When last did the logging work - any changes that may have caused the logging to break?
→ last entries in openhab.log and events.log are from October 11
→ yes I made changes, but I don’t really remember the details …
Did you upgrade from <3.0?
→ no, I started from scratch with 3.0 and did some steps towards 3.2.0.M3

3b. /var/lib/openhab/etc/org.ops4j.pax.logging.cfg was emty
→ I copied one line from a backup file

Bingo 1 : openhab.log is filled again !

events.log is still on October 11, no update up to now

Mark_VG · November 1, 2021, 12:15pm

Try get the latest log4j2.xml from GutHub. That was how I fixed mine.

Paul_Vennhaus · November 1, 2021, 3:42pm

I loaded log4j.xml from here
github.com log4j2.xml
restarted openHAB, event.log is still on October 11, no update up to now.

Mark_VG · November 1, 2021, 4:09pm

Maybe try rename or delete events.log and see if it is recreated.

Otherwise I am out of ideas.

Paul_Vennhaus · November 1, 2021, 4:26pm

That’s it!
The solution is:

/var/lib/openhab/etc/org.ops4j.pax.logging.cfg was emty
→ I copied the one and only line from a backup file
----> openhab.log is filled again !
I deleted the events.log and restarted openHAB again, now all seems to be alright!
----> events.log is filled again !

Thank you very much Mark.

+1 here (openhabian 3.2.0-SNAPSHOT - Build #2570):

My org.ops4j.pax.logging.cfg was empty.

Adding
org.ops4j.pax.logging.log4j2.config.file=${karaf.etc}/log4j2.xml
and restarting the openhab service solved the problem.

In my case, deleting events.log wasn’t necessary.

@Paul_Vennhaus
Thanks for documenting the solution!

JimT · April 30, 2022, 8:29am

Thanks! I just came across this issue. You’ve just saved me a lot of time.

hafniumzinc · March 18, 2023, 9:04am

I’ve just had to do this on a 3.4.1 install after getting

Error executing command: Unrecognized configuration

when trying log:tail and log:display in the console.

This solution worked for me!

florian-h05 · November 28, 2023, 6:29pm

FYI I just had the same issue, however openHAB reverted my addition of that line to the file on restart.

However I luckily was able to fix it using the openHAB console using these commands:

config:edit org.ops4j.pax.logging
config:property-set org.ops4j.pax.logging.log4j2.config.file /var/lib/openhab/etc/log4j2.xml
config:update

stagf15 · May 21, 2024, 1:36pm

I know this is an old thread, but I just upgraded to OpenHAB 4.2.0.M3 from 4.2.0.M2 on Linux using the package repository (sudo apt upgrade) the way I always do, and I had the same issue. I tried the instructions that @florian-h05 recommended above (editing via console using commands) and they worked perfectly. I did not try editing the file directly. Thanks for help!

kdb · June 16, 2024, 12:18pm

Hey, what is the one and only line ?
Can you post it ?
Thanks
