There are four Cisco CPU checks: cisco_cpu, cisco_cpu_multiitem, cisco_nexus_cpu, cisco_oldcpu. We discover the Cisco CPU utilization services in the following order:
-
if it's a Nexus device the cisco_nexus_cpu check is used
-
if the device contains the SNMP table .1.3.6.1.4.1.9.9.109.1.1.1.1.8.* then cisco_cpu_multiitem is used
-
if the device has the OID .1.3.6.1.4.1.9.9.109.1.1.1.1.5.1 then cisco_cpu is used
-
if .1.3.6.1.4.1.9.2.1.57.0 exists then cisco_oldcpu is used
After firmware updates there may be deprecated OIDs like .1.3.6.1.4.1.9.2.1.57.0 or .1.3.6.1.4.1.9.9.109.1.1.1.1.5.1. In such cases you have to re-discover the related hosts.
There also may Cisco hosts which have discovered the 'wrong' check type. After a re-discovery the CPU check type may change.
