I have an old graphing program that simply monitors one of the snmp variables showing the temperatures shown in IOS command "Show Environmental Temperature all". I added the Cisco System Health sensor, which is vast and shows me 90% of things that I've never monitored before, but are great. However no temperatures showing.
Can't I just create a sensor that monitors a single snmp MIB OID (like my old dirty program does)? Can't see a way to do that. I assume it's my inexperience with the system, but this is a real important value.
