The correct MIB to use is shown below and is used to monitor all processors in a chassis. The actual device is referenced by the Index and corresponds to the ENTITY MIB as shown below...

It is very important to monitor the Route Processor and Switch Processor in a 6500 chassis to make sure you are not software switching packets, which can show up as high Route Processor CPU load. This will also show you other module CPU loads.

"cisco.ciscoMgmt.ciscoProcessMIB.ciscoProcessMIBObjects.cpmCPU"

The index reference is in the...

"mib-2.entityMIB.entityMIBObjects.entityPhysical.entPhysicalTable.entPhysicalEntry.entPhysicalDescr"

There are two ways to do this:

1) freeMem - I think this is an old Cisco mib and
2) the Cisco memory poll mib
variables; ciscoMemoryPoolUsed and ciscoMemoryPoolFree
(CISCO-MEMORY-POOL-MIB)

I use Netcool Precision and this contains a cisco memory % threshold poll
definition using (2) i.e.

( ciscoMemoryPoolFree/(ciscoMemoryPoolUsed + ciscoMemoryPoolFree) )* 100

Hi,

For Netview 7.1.5 on Windows, to monitor Cisco Memory utilization SNMP
data
collection, can we make any MIB Expression or is there any Cisco MIB
available to do this

Thank you in advance.
