APC apcupsd.conf Temperature Error (APC Smart-UPS 1500 RM)

Hello dear CheckMK Community,

Lately (I think after Upgrade to 2.1.0) the APC Temperature service crashes.
The APC is directly connected (via USB) to our Hypervisor (Proxmox VE, Hostname: pve).
APC Status Services is OK (still works, never stopped).
I don’t exactly know why this happens but I guess it has to do with CheckMK APC check, as we have not done any Firmware Upgrades on the APC.
Executing the Check apcaccess on the host directly yields the following output (which seems normal to me):

<<<apcaccess:sep(58)>>>

Is anybody else having this (or a) problem with APC devices?

Best regards,

It looks like there is an incompatible change in the check_temperature() function between 2.0 and 2.1. :frowning:

The unique_name and value_store parameters are not optional any more.

Compare checkmk/temperature.py at 2.0.0 · tribe29/checkmk · GitHub and checkmk/temperature.py at 2.1.0 · tribe29/checkmk · GitHub

This is not nice, @LaMi as we contributors now have to redo all check plugins (again). check_temperature is not part of the versioned API but part of the utils module, but it would still be nice to have a stable interface here. I even did not find a Werk announcing that change.

Let me check the background.

Hi @r.sander @Pixelpoint,
this has been fixed with Werk 13730 and is available with Checkmk 2.1.0p4.

That was fast. :slight_smile: :smiley:

Dear @LaMi , @si-23 and @r.sander : Thank you very much for your help.
I will wait until I can download 2.1.0p24 and if it fixes the issue, will mark @si-23 comment as solution.

Thank you very much!

PS:
Yes, that was blazingly fast :smiley:

Best regards,
pixelpoint

Ok, so after updating to 2.1.0p24, I get a different error.
