When I try to do an snmp walk in nagios, the only info I get is the interface name and link state, and the description I entered, plus throughput. It seems that all of the info from the snmp walk is coming from 1 maybe 2 MIBs that seem to be on nagios already. I started reading the nagios documention about the snmp walk and MIBs. Am I correct in saying that for nagios to show the other info ie chassis temp, fans, power, cpu that I need to load the Cisco MIBs that I got for my specific ios / switch. I downloaded all the v1 and v2 MIBs, but they are not in a txt format like the ones in nagios already. They are in .cd, .my and I forget the other extension. If I do need to import these for the snmp walk to get the info I want in the walk, which extension do I need to upload? Pardon my questions, as I am new to snmp / oid / MIBs. I am trying to understand it as fast as I can.
Thanks
