do to snmp variable names ;-)

cpu usages: .iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt \
.ciscoProcessMIB.ciscoProcessMIBObjects.cpmCPU.cpmCPUTotalEntry \
.cpmCPUTotal1min

Here's how we figure out what cpu's are which (note this is buggy
on some releases as there are problems with either the SP or RP
having a correct entry in the cpmCPUTotalEntry instance to EntityMIB.
I filed a TAC case, and I think it's fixed in SXE?):

- take a look at mib-2.entityMIB
entityMIBObjects.entityPhysical.entPhysicalTable.entPhysicalEntry \
.entPhysicalDescr

- check out ciscoCat6kCrossbarMIB:
ciscoCat6kCrossbarMIB.ciscoCat6kXbarMIBObjects.cc6kxbarStatistics \
.cc6kxbarStatisticsTable

active flows are great for DDOS detection:
cseL3Objects.cseL3StatsEntry.cseL3ActiveFlows

Ext flow invalidations: 
cseL3Objects.cseL3StatsEntry.cseL3ExtFlowInvalids
Int flow invalidations: 
cseL3Objects.cseL3StatsEntry.cseL3IntFlowInvalids
total l3 pkts:  cseL3Objects.cseL3StatsEntry.cseL3SwitchedTotalPkts

tcam usage: (i think this one is it, need to update my mib browser, 
sorry)
.iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt \
.ciscoSwitchEngineMIB.9.1.1.2

memory pools:
ciscoMemoryPoolMIB
ciscoMemoryPoolUsed
ciscoMemoryPoolFree
ciscoMemoryPoolLargestFree
ciscoEnhancedMemPoolMIB.cempMIBObjects.cempMemPool.cempMemPoolTable

And whatever else you can think of.

Enjoy!
