Request to disable verbose logging by default

[MarkBurchard]

The verbose logging creates a large logfile (>500MB) (Found on the UDM Base at /mnt/data/podman/storage/overlay-containers//userdata/ctr.log)

The UDM Base has 12GB internal storage. A ~500MB logfile represents roughly 8-10% of the available free space on the /mnt/data partition, which makes me nervous. It's become an ingrained habit to truncate CTR.log every few days.

Alternately, is there a way to launch the container with verbose logging turned off that would persist over restarts/reboots?

it only logs to stdout - i wonder if something changed on the unifios podman instance to log that to a file? AFAIK it never used to do that, at least no one has ever reported it, and i don't recall seeing it. (if this is the case this will be an issue for many community containers...)

I can change the default on the verbose but will need to rebuild;

@MarkBurchard I pushed a new build, can you see if that turned off the verbose env var?

[MarkBurchard]

Pulled the new build. The logfile is at 12MB after ~2 hours. That seems like an improvement but I'll check the growth delta again tomorrow to be certain.

The actual content of the log output looks the same to me but since I don't have a copy of the pre-change logs I can't say for sure.

Thanks for taking a look at this. I'll post an update tomorrow.

thanks for doing that, can you shell into the container (or docker inspect) and make sure the env var didn't get set - that will validate verbose got turned off (if i have time i will try and look over weekend too).

[MarkBurchard]

So at ~21 hours ctr.log is 60MB. I can't quantify the reduction in logfile size but that is definitely lower than the rate of +500MB every 3 to 4 days.

I tried to log into the container but got a cgroups error that I'm still troubleshooting. When I run a ps I still see the verbose OPT (which I omitted from my initial run command):

ps -ef | grep verbose

5697 root grep verbose 29246 root python3 ./multicast-relay/multicast-relay.py --interfaces br5 br10 --foreground --verbose

So it seems like the problem is solved or at least greatly mitigated and I'm good with that but I'm still puzzled as to the mechanics of it ;-) If I find time I'll try to dig into a little further but for now I'm perfectly happy to be the beneficiary of mysterious good luck...

Thanks again for looking into this.

closing as resolved, if more changes are needed open a new issue, thanks for the feedback!
