Eaton 9130 - Temperature not being obtained from UPS

Help

Please advise if there is something specific I need to do. It seems to be reading and graphing everything, except temperature. Screenshot from the SNMP management card from the UPS itself shows the battery temperature correct.

Hello!

We have a couple of Eaton devices with the same symptoms. I had a little peek in the polling process and found the following:

  1. LibreNMS uses generic UPS-MIB for Eaton monitoring, at least for our model.
  2. sysObjectID refers to MG-SNMP-UPS-MIB::upsmg.
  3. In UPS-MIB there is a dedicated temperature OID: UPS-MIB::upsBatteryTemperature, which returns “0” as a value via snmpwalk/snmpget.
  4. In MG-SNMP-UPS-MIB there is a dedicated temperature OID: MG-SNMP-UPS-MIB::upsmgEnvironmentTemperature, but unfortunately, it also return “0” as value.

So in our case the problem is not with LibreNMS, but with the device itself, or more precisely - how it returns temperature via SNMP.

Thx. Will see if there is an update for the snmp card.
