Nexus Power Supply OID's

Hi Andy -

Yes, the 101, 102 etc are definitely referring to your Fex units - that's how they are labelled on an interface basis by default (i.e. Int eth101\0\1 for the first interface on the first Fex)

Looking at the ID results, I think that the Row ID values are as follows:

22    Supervisor

470   PS 1

471   PS 2

When i do a show env power on one of my 5010s I get the following - the fact that the supervisor is reported as powered-up seems to hint that it's what OID 22 refers to:

N5010-6-01# sho env power

Power Supply:

Voltage: 12 Volts

Hi John

Thanks for this, i'll start polling for these and hope it doesn't have any ill affects on the Nexus (they are sensitive souls after all, well ours are for some reason). Really appreciated the help.

No problem Andy - I've just found this which goes into a bit more detail:

Thanks again.

Hi AndyRoberts​, Did you ever get to the bottom of this? Do you know the correct OID to poll for Nexus power supplies? I am trying to poll the same for Nexus 7K's. Cheers

Hi. On NPM12 it should be capable of monitoring Nexus 7ks Hardware out of the box now. What version are you running?

11.5.3. We are going to upgrade to 12 very soon, it's just that our primary poller has 8G RAM and the minimum stated in the NPM 12 Admin guide is 16G whereas the recommended is 32G, so I htough I don't need to put our box under any more stress so we'll upgrade post server migration. What's the monitoring like on Nexus in 12?

My goal here is to create the most immediate warning I can regarding power supply on our Nexus Core, Our NOC is complaining that mails are not immediate enough. I was thinking I would create a report base on a custom poller that will display any nexus box which is returning anything other than a 2 (OK)when polled for cefcFRUPowerOperStatus and then publish this report on the NOC web console home page. Is cefcFRUPowerOperStatus the right OID to poll though? Also when you consider the output can be '2,2' when there are 2 supplies, this might make the report a little more difficult to create if at all possible. Has the monitoring/alerting improved in 12?

Hi

NPM 12 is much better for monitoring and alerting in my opinion and more information available of the box now. To give an example for Nexus 7 this is what Hardware Details looks like in NPM12.

Hope this helps.
