[c-nsp] MIBs for Processor and Memory utilization?

[McLean Pickett]

The SNMP Object Navigator is supposed to be able to tell you what MIBS
are working on your device. It allows you to search for supported MIBS
based on ios image file name - THOUGH it doesn't support any of the new
ISR's (1800,2800,3800) so its not helping me.

Now, not really.. the main problem is, you don't know/see what mibs are
indeed working on your devices..
Pull down the MIBs and walk a (non-production!!) router with snmpwalk -m
ALL enterprises on some linux box; it's the easiest way to find what I
need for me.

Here's what we use for monitoring on 17xx - 72xx, some things like
mem-OID's vary by  platform & IOS but walking parents should give you
what you need: 

ciscoMemoryPoolMIB
Process-mem free .1.3.6.1.4.1.9.9.48.1.1.1.6.1 IO-mem free
.1.3.6.1.4.1.9.9.48.1.1.1.6.2 

OLD-CISCO-SYS-MIB
CPU avgBusy1 minute .1.3.6.1.4.1.9.2.1.57.0 CPU avgBusy5 minute
.1.3.6.1.4.1.9.2.1.58.0
