Periodic temp sensor spikes since last update?

[bl4ckswordsman]

I've noticed some periodic (about every 4 minutes) high temperature spikes(from 40 to 80°C) on one of my sensors (acpitz), which seemingly started to happen since the latest 0.18.6 update.

I've been troubleshooting and trying to find the culrpit for a while now, and I ended up in suspecting Beszel itself as this started occuring when it was last updated.

I'm guessing it has to do with the collection of some sort of stats but I can't pinpoint which ones from the release notes.

I'm running Beszel in Docker/Linux.

Only on that sensor? Sometimes sensors can report bad values. You can try a versioned image tag like :0.18.4 or :0.18.4-alpine if you want to try going back to an earlier agent version.

Just for reference I don't see this problem with the binary agent, on any of my systems the acpitz sensor is stable.

Might be worth to check when it happens what is returned by the sensor. As @henrygd mentioned sometimes there might be a bad value returned by it. Similar was reported in #1815

cat /sys/class/hwmon/hwmon*/temp*_input

Thanks a lot for your replies!

I looked into some other services I host and the acpitz sensor temperature seems to have normalized now.
Unless this resurfaces, the issue is solved and my suspicion of beszel being the culprit was most likely incorrect.

I'm seeing odd temperatures with the alpine version as well (Running alpine for tailscale/unraid support) Posting a look at my sensors if it's of any value.

My understanding is certain sensors just output total garbage and should be ignored entirely. Is it possible to hide certain sensors?

[svenvg93]

You can "blacklist" them to be ignored with SENSORS environment variables.

Just out of interest since more people are reporting this suddenly. Did you just installed the agent or did it happen after an agent update?

Awesome, I'll check it out thanks. I only installed yesterday, I noted the sensor issue on both latest and alpine but my understanding is that these particular sensors are super unreliable (This mobo is quite old ~2013).
