I have Nagios Core 4.2.1 installed on Centos 7. I wan't to monitor cisco switches by snmp oid's.
For exmaple, I got the oid 1.3.6.1.4.1.9.9.109.1.1.1.1.5.1 ( Cisco CPU load 5min). I know, I can easily monitor this with "check_snmp" plugin, but the output is "SNMP OK - 4". I wan't to see the percent of the CPU load.
Theoretically, yes. It's more dependent on the OIDs your remote system's SNMP agent is providing than anything. check_snmp just grabs an OID and compares it's returned value to a provided threshold or expected value.
