nms-server>snmpwalk -c public 14.32.6.12 cpmCPUTotalTable
CISCO-PROCESS-MIB::cpmCPUTotalPhysicalIndex.9 = INTEGER: 1011
CISCO-PROCESS-MIB::cpmCPUTotal5sec.9 = Gauge32: 7
CISCO-PROCESS-MIB::cpmCPUTotal1min.9 = Gauge32: 7
CISCO-PROCESS-MIB::cpmCPUTotal5min.9 = Gauge32: 7
CISCO-PROCESS-MIB::cpmCPUTotal5secRev.9 = Gauge32: 7 percent
CISCO-PROCESS-MIB::cpmCPUTotal1minRev.9 = Gauge32: 7 percent
CISCO-PROCESS-MIB::cpmCPUTotal5minRev.9 = Gauge32: 7 percent
