I was recently asked if it was possible to monitor the temperature of a Cisco device so it can be seen on its node detail page. I replied of course, that's as easy as adding a universal poller hitting the ciscoEnvMon. However, with the Nexus, that isn't the case.
From the documentation that I could find, the OID to pull this sensor data out of the Nexus is in the CISCO-ENTITY-SENSOR-MIB using the entSensorValue OID (1.3.6.1.4.1.9.9.91.1.1.1.1.4) to return the table of readings. I then used the CISCO-ENTITY-ASSET-MIB to build a crosswalk from the index on both to return the name of the monitoring point with temperature measured. This is a manual process, however, and right now I am just using NPM to store the polls so the temperature data can be analyzed at a later time.
Has anyone else done anything with monitoring environmental elements on the Nexus?
