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

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
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):


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

  1. 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 …

  2. 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


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

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

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

Otherwise I am out of ideas.

That’s it!
The solution is:

  1. /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 !

  2. 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.

and restarting the openhab service solved the problem.

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

Thanks for documenting the solution!


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

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!

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
