Alert for down Power supply on Nexus 7009

[nesrin]

Hi,

I am working on nexus 7009 and I am getting Alert on Librenms (monitoring software) for down power supply&fan  although when I check  switch log (sh logging)  there is no log for down power supply.

So I took a screen shot during the alert and after alert recovery and attached it below, on the left is during critical alert while the one on the right is after recovering. Are those Actual output number of power supply showing why we are having the issue?

           - What's the native source of this alert? If it is an snmp-trap for instance, try to capture it fully.

I am using SNMP. Here is capture during recovery time I'll capture another one when I receive a new alert
Snmpwalk for 1.3.6.1.4.1.9.9.117.1.1.2.1.2

check NMS what OID it try to poll and try yourself with snmpwasl and see you can reproduce the error ?

make sure NMS has right OID download from cisco and added.

NMS is checking OID cefcFRUPowerOperStatus and sending alert for Supervisor Module-2 is down in addition to all listed below:

I will wait for next Alert to be generated and test snmpwalk to see if I really have issue.

 - Sometimes this can be due to a software bug (false alert) ; further check power supply status with :

                                    show env power detail

Hi All,

Sorry for not updating you. Suddenly Librenms stopped sending Alerts. I think what cause the Alerts is bug described in " https://bst.cloudapps.cisco.com/bugsearch/bug/CSCtf99048/?rfs=iqvred "

Thank you all for your help.
