hhhmmm... that makes quite the difference. My previous post to this
thread is completely irrelevant, that was for monitoring cpu load on a
linux box. My example below is for cisco 3845 and 7206 routers but it
gives you the idea... you just have to find your specific OIDs (that's
really the hard part unless someone else here can provide those
numbers). If you're paying attention you'll notice the OIDs for both
routers are the same (in this instance). I had to really dig around to
get those numbers and don't recall where I finally found them. Sorry.
Well, there are different OIDs supported depending on which version of IOS
you run on your Cisco box.
One way is to do an snmpget using the different OIDs and see which ones that
gives you a number.
A good tool for looking in to OIDs is OidView (You can download a demo from
their web site and check it out, www.oidview.com)
The OID mentioned by Steve Lindeman is from an outdated MIB
(OLD-CISCO-CPU-MIB).
I recommend you using OIDs from the newer CISCO-PROCESS-MIB
