The Cisco CPU checks discovery ordering from Werk 7458 is revisited.

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 .* then cisco_cpu_multiitem is used

- if the device either the OID . or . then cisco_cpu. This acts now as a fallback and is not strict about verifying device not belonging to cisco nexus family. This as a relaxed condition to werk 5748.

- if . exists then cisco_oldcpu is used

There may be Cisco hosts which have discovered the 'wrong' check type. After a re-discovery the CPU check type may change.
