check_snmp - Cisco PIX 515E OID


I am trying to get CPU stats from my Pix 515E using check_snmp. I have searched high and low for the proper OID.

Cisco website indicates:

This of course doesnt return anything. I have tried snmpwalk of the pix and cant find that OID.

The closest I can come is:

Which doesnt show anything related to CPU stats. From what I gather from Cisco’s snmp tool the .58 should work. Anybody have any clues for me?


The cpu utilization of pix 515e


oid : .



Thanks for your help.

I must be missing something…

If I run snmpwalk on my host:
snmpwalk -v 1 -c nagios -On .

I receive the following response:
. = Gauge32: 0

If I try and run check_snmp:
check_snmp -H -C nagios -o .
SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 1 -c nagios .

How does the MIB come into play? I tried running the same check_snmp with -m CISCO-PROCESS-MIB to see if that made any difference but no luck.

What am I missing, thanks again.


I think I have it now…

check_snmp -H -C nagios -o

Returns the 5sec utilization.

Thanks again…
