No logging in Karaf console possible

Setup, Configuration and Use Runtime
1
  • Platform information:
    • Hardware: Pi 3 B+
    • OS: OpenHabian
    • Java Runtime Environment: ?
    • openHAB version: 4.3.2

I had a crash of my previous installation (Version 3.?; SD damaged) and had to setup a new installation from scratch (4.3.2). I had a backup from the old one and restored it. Everything fine so far, but not able to debug. If I open a Karaf console and try to set debug level log:set or using any other log command: “command not known”.
After 4-5h searching the forum I already checked:

  • in org.ops4j.pax.logging.cfg everthing fine: “org.ops4j.pax.logging.log4j2.config.file=${karaf.etc}/log4j2.xml”
  • log4j2.xml looks fine, too
    No more idea, how to solve it. Even thinking, going back to OpenHAB 3.something.

Often when there is a problem with logging there will be something logged out by systemctl. Is there anything relevant in

sudo systemctl status openhab

If it says something about the journal having been rotated restart OH and run it again.

Beyond that, with the information provided all I can recommend is to double check the permissions on the logging config files and /var/log/openhab folder.

I am not very smart in linux: Is this the required information?

Please use code fences in the future for code, logs, output from command lines and such to preserve the white space.

```
code/logs go here
```

The output from systemctl does not show anything wrong with the logging itself and the file permissions looks correct.

The dates on openhab.log shows it’s been written to recently. What’s being logged there? any relevant errors there? events.log isn’t being written to at all, do you not have any Things or Items being updated since Feb 3rd?

Compare your log4j2.xml file to the original unmodified config: openhab-distro/distributions/openhab/src/main/resources/userdata/etc/log4j2.xml at main · openhab/openhab-distro · GitHub

Will come back tomorrow. Too late for tonight.

No change of the situation so far.
I don’t understand, why in the log “Starting openHAB 4.0.4” is mentioned. Version is 4.3.2.

I got it: I tried to remove the HUE-BIinding by UI => no success, but with the help of “Cant Remove Bindings” I identified the number of the binding, could delete it, after cleaning the cache and reboot …
Now everything is fine again
