I’m currently having an issue with my log files. When I start openHAB, openhab.log / events.log start logging as expected. At some point though, no new entries get added to the log files. Sometimes it’s 20 minutes later, sometimes 3 hours - totally random. The rest of OH works as usual. There’s also nothing irregular in the logs just before it stops.
I already re-downloaded the log4j2.xml, but that didn’t help.
The only thing I noticed is this in dsmeg, I’m not sure if that could be related though:
[10410.361696] systemd-journald[899]: /var/log/journal/1fb0bf70d28e4417ab7c45e395d422ad/user-1001.journal: Journal file has been deleted, rotating.
[10410.361711] systemd-journald[899]: Failed to write entry to /var/log/journal/1fb0bf70d28e4417ab7c45e395d422ad/user-1001.journal (21 items, 834 bytes), rotating before retrying: Identifier removed
I had the same issues with the logfiles when using an SSD as a test scenario, so I guess that would rule a corrupted SD card out.
Any ideas on what could be causing this are highly appreciated.
Platform information:
Hardware: Raspberry Pi 5 Model B Rev 1.0, 4GB, 32 GB MicroSD
OS: openHABian v1.9c
Java Runtime Environment: openjdk version “17.0.11” 2024-04-16
Same issue here. New installation of Openhabian from an image (4.1.2)
There is no issue with log4j2.xml as suggested by pguima. I even tried with a clean version of log4j2.xml from the Openhab repository.
If I type “log:tail” in the console, all messages are shown and the log files start to update.
After a couple of hours the logging stops again (the files show no updates).
Yup, log4j2.xml is fine on my side as well.
However, when I run log:tail on the console, I see like the last (most current) 50 entries or so but then it ends with Error executing command: Unable to set level for logger.
When I run it again a bit later, I also get the latest entries (so it does update), but it still ends with Error executing command: Unable to set level for logger.
Thing is: the log files don’t get updated - events and openhab.log both stopped updating at 0:04 this time.
Try disabling zram sync systemctl disable --now zsync.timer.
issue some log related command on OH console like log:set debug xzy to get logs going again.
Even stranger: Logging worked until 12:02 PM today.
Then suddenly the frontail view started scrolling through older events for several seconds and stopped at 10:25AM.
events.log got a new timestamp of 10:25AM
Logging is now stuck
As soon as I issued the log:tail command the logging started working again, but entries between 10:25 and 12:02 are lost.
Thanks for your reply. I tried what you suggested, unfortunately log:set debug 291 still returns Error executing command: Unable to set level for logger.
I have the same issue but I’m not using zram. I did a full reinstall on a fresh SSD and restored my backup, but it still stops logging after a certain amount of time (usually around 30 mins).
I just tested the log:tail command and then logging resumes.
This thread made me wonder, so i checked. My openhab.log is fine, but my events.log stopped logging in november '23 (!). I’m on Openhabian, 4.1.1 - Release Build and using zram with plenty of space:
df -h /var/log
