    Need to located OID in order to create UnDP to monitor Power supplies on a Nexus 7018

    jclukey

      To all:

      I am trying to locate the OID by which I can monitor the status of the power supplies in our Nexus 7018s much like I do for our other Cisco gear (e.g. 6509s, 6513s, etc.).

      I suspect the OID is under the 1.3.6.1.4.1.9.9.117 tree but I could be way off base on this one. I've been looking for quite some time now and can't quite get it. I thought it was 1.3.6.1.4.1.9.9.117.1.1.2.1.2 (cefcFRUPowerOperStatus) but the values returned are 2,2,2,2,2,2,2,2,2,2,2,2,2,2 (14 2's).

      Now there are only 4 'slots' for power supplies and we have only populated 3 of them. 3 6K Watt power supplies with 2 220V power sources. So, if this 'is' the OID to poll I haven't been able to figure out what all of the values are for?

      Any help would be greatly appreciated it. TIA.

          The following entry from the Engineer's Toolset MIB Browser may be of use:

           

          CISCO-ENVMON-MIB:ciscoEnvMonSupplyStatusTable

          OID:
          1.3.6.1.4.1.9.9.13.1.5

          Access:
          Not-Accessible

          Type:
          Sequence

          (Don't be over-concerned that it says "Not-Accessible" - this is because it is a table, so you need to delve deeper into it.)

          Hope this gives you a start :)

            Do you have FEXes connected to the 7018? I have a Nexus 5548 with 4 FEXes connected to it and I get the following results:

            199000470On
            199000471On

             

            I translated the number 2 to "On". In the left column, the numbers starting with 101, 102, 103, 199 are the FEX. Those are the fex numbers I have assigned to them. The first five are for the Nexus 5548. 470 and 471 are for the actual power supplies (you thse those on the FEX too). The other numbers I'm still trying to figure out.

                Have you managed to get the system to alert where both power supplies have issues, but not enough to power the node down?  The reason i ask is because i have been using same cefcFRUPowerOperStatus MIB to poll the state of the FEX's, however i have seen an issue today where one of the FEX's is reporting issues with both PSU's (so getting the whole FEX replaced), but the only identification that there was a fault was that the table itself lost two of its entries. For example if you see below i have an entry for each Fex's Supervisor, PSU1 and PSU2, but you will see that FEX 111 is only seeing the Supervisor. Does anyone know how to alert when these go missing?
