Our UPS turned from one day to the other into a warning state. The battery has to be replaced, but CheckMK remains fully green.

I looked and researched about Battery State (check_mk-ups_battery_state). I also hoped to find the actual check file to gain insights to the used OIDs, but couldn’t find that file.

The overall question: Why does Battery State not indicate the needed battery replacement?
Side question: in the past, I looked into the detail page of the check under “Service check command” to investigate checks, but cannot find hints to “ups_battery_state”.

2

On your system the battery state is done with the check - ups_battery_warnings_eaton_mg
This check uses the shown list of OIDs.

If these are the corrects OIDs and check can only be said with an snmpwalk on this device.

But the OID subtree .1.3.6.1.4.1.705 is not the correct one for Eaton.

.1.3.6.1.4.1.705 = No Such Object available on this agent at this OID

This subtree looks more promising:
