CPU Utilization on Cisco routers that have multiple CPUs

Anyone have any elegant and scalable method of monitoring CPU
utilization on Cisco routers that have multiple CPUs? I know I can
specify more than one OID with check_snmp, but I would need to know the
exact OID for each CPU like this: cpmCPUTotal5minRev.1,
cpmCPUTotal5minRev.2
But as you can see below, the OID is variable and the total number of
CPUs/OIDs will range for each router.
$ snmpwalk -m ALL -c readstring router1.domain.com cpmCPUTotal5minRev
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.1 = Gauge32: 1 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.2 = Gauge32: 1 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.3 = Gauge32: 0 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.4 = Gauge32: 5 percent
$ snmpwalk -m ALL -c readstring router2.domain.com cpmCPUTotal5minRev
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.1 = Gauge32: 1 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.3 = Gauge32: 4 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.8 = Gauge32: 16 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.9 = Gauge32: 0 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.10 = Gauge32: 0 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.11 = Gauge32: 7 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.12 = Gauge32: 0 percent
I'm at a loss here on this one. I would be curious how others have
router CPU utilization monitoring implemented out there.
