I have Cisco C9300 switches, both with 1 PSU and with 2 PSUs and monitor these with LibreNMS. Although almost everything works out-of-the-box I do encounter a problem with the PSU alerting.
When I use the switches with 1 PSU the second PSU has state 5 ‘notPresent’ on CiscoEnvMonState/ciscoEnvMonSupplyState (OID .18.104.22.168.22.214.171.124.126.96.36.199.3) and state 1 ‘offEnvOther’ on cefcFRUPowerStatus/cefcFRUPowerOperStatus (OID .188.8.131.52.184.108.40.206.220.127.116.11.1.2).
The alert is given for cefcFRUPowerOperStatus for being off although the power supply is not present.
I’m open to suggestions on how to fix this so that when I add new devices they won’t give an alert if the power state is off and the power supply isn’t present. Could you please help me?
