Hi Elijah,

What I'm using for grabbing the CPU utilisaton off our SIP-200s and SIP-400s is
as follows:

If you poll .1.3.6.1.4.1.9.9.109.1.1.1.1.5, this gives a list of the 5 minute
CPU utilisation on the box:

(22:46 - /dev/pts/27) bronze:~> snmpwalk -v2c -c community rtr .1.3.6.1.4.1.9.9.109.1.1.1.1.5 
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.1 = Gauge32: 10
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.2 = Gauge32: 5
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.3 = Gauge32: 1
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.4 = Gauge32: 1
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.5 = Gauge32: 1
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.6 = Gauge32: 0
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.7 = Gauge32: 0
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.8 = Gauge32: 0
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.5.9 = Gauge32: 1

Each of these entries can be resolved into a physIndex via polling 
1.3.6.1.4.1.9.9.109.1.1.1.1.2 

(22:48 - /dev/pts/27) bronze:~> snmpwalk -v2c -c community rtr 1.3.6.1.4.1.9.9.109.1.1.1.1.2
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.1 = INTEGER: 6017
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.2 = INTEGER: 6001
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.3 = INTEGER: 2011
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.4 = INTEGER: 2012
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.5 = INTEGER: 3011
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.6 = INTEGER: 3012
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.7 = INTEGER: 4011
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.8 = INTEGER: 4012
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.9 = INTEGER: 1011

The Entity MIB then gives you the CPU that these correspond to:

(22:49 - /dev/pts/27) bronze:~> snmpget -v2c -c community rtr 1.3.6.1.2.1.47.1.1.1.1.7.2011
SNMPv2-SMI::mib-2.47.1.1.1.1.7.2011 = STRING: "cpu 2/0"

(slot 2 in this case is a SIP-400. I get a linecard utilisation for each slot in
the box)

I believe that this should let you monitor the CPU of the SIP.

Hope this helps,
Rob
