Ah, these objects are very useful, thanks. I have noticed the TCL policy is run in a process named EEM TCL Proc, which I can then monitor along with EEM Server and EEM Helper Thread. Indeed it seems to return 0 every time, although this is not unexpected as the runtime (usually) is less then 5 seconds. Any idea if there are more processes I should monitor?

Hello all,
I have implemented two EEM Policies using TCL on a Cisco Catalyst 6500, both of them running every X seconds. Now I am trying to find a way to monitor the CPU and memory usage of these policies, to determine their footprint. Does anyone have a good idea how I can do this?
It looks like cpmProcExtUtil5SecRev is what you need. This should be available but it might depend on your IOS. CISCO-PROCESS-MIB shows all the different incarnations of it. You can also use cpmProcExtMemAllocatedRev and cpmProcExtMemFreedRev to track memory usage.
Use cpmProcessName to find the process you want to monitor (in this case grepping for PID but you can look for name):
[rdrake@machine ~]$ snmpwalk -v2c -c community routername 1.3.6.1.4.1.9.9.109.1.2.1.1.2 | grep 318 SNMPv2-SMI::enterprises.9.9.109.1.2.1.1.2.1.318 = STRING: "ISIS Upd PUR"
The 1.318 is the important bit.
[rdrake@machine ~]$ snmpwalk -v2c -c community routername 1.3.6.1.4.1.9.9.109.1.2.3.1.5 | grep 318 SNMPv2-SMI::enterprises.9.9.109.1.2.3.1.5.1.318 = Gauge32: 0
One problem being that this is a percentage with a minimum resolution of 1% (integer based) so even though this is the busiest process on the box I tested on, I always got zero percent. It should be good for thresholding if you want to make sure your process doesn't spike the CPU though. Also, the PID might change every reboot so long term monitoring might be problimatic unless you can associate the process name with the other thing.
