What you really trying to accomplish here? SNMP is low-priority process it doesn't affect any routing protocol they are have medium priority.

If cpu idle it will allocate all available resource to snmp. Unless you are having problem with routing protocol which cause timeouts, there nothing you should do.
Otherwise upgrade to latest IOS, you seems running ancient version already. But be warned 15.1 upgrade will require firmware update on 3560X platforms it takes about 25mins.

I added Obersvium for one of our workstation cisco switch which has most ports filled up

Now the switch gets huge CPU spikes at random times And it points to SNMP ENGINE PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 263 959593774 37162365 25821 81.62% 19.01% 7.03% 0 SNMP ENGINE 263 960182122 37166258 25834 75.33% 12.91% 5.58% 0 SNMP ENGINE
Is there a way to lower the cpu spikes? Updated Observium? Update Switch OS? ? Limit polling information?
