Seeking Cisco switch memory use per process via SNMP

Hi guys,

​

I'm trying to get memory use per process via SNMP for some Cisco switches (3750s and 3560s).

​

The CISCO-PROCESS-MIB exposes cpmProcExtMemAllocatedRev and cpmProcExtMemFreedRev and I've found a link that suggests subtracting freed from allocated (https://networkengineering.stackexchange.com/questions/19114/cisco-process-memory-usage)

​

Unfortunately this doesn't seem to provide sane values- often my freed is greater than my allocated (I daresay because some memory is freed in the time it takes me to gather the allocated and the freed).

​

At any rate, looking at the output of the show processes memory command shows that Allocated and Freed may sometimes be the same and the interesting looking column is Holding.

​

Switch3#show processes memory

​

I can't find references to Holding anywhere in that MIB, so- does anyone know how to get memory holding per process via SNMP? (I haven't been successful in Googling it)

​

Thanks
