SNMP With Cisco

Hi,
I am new to the Dude however I think its a great tool, I have an issue though that I hope someone can help me with. I am mainly using it to monitor my Cisco devices and the bandwidth of the links between them. When I setup the SNMP string and the dude probes the Cisco devices the CPU utilization on my Cisco device shoot up to 80-90% for around 5-10 seconds. I think this is because by default the Dude is taking every possible SNMP value however I don't require all this information. Is it possible to configure only a selection of SNMP data to probe?

Thanks

Stephen

We are using this software to monitor 700+ devices a very large percentage of these (95%+) are cisco devices.
the Probe I setup contains the following, I am not seeing any spikes in my graphs currently.
================
Name: Cisco CPU
Type: Function
Agent: Default
Available: if(oid("1.3.6.1.4.1.9.2.1.58.0")>0, 1, -1)
Error: if(oid("1.3.6.1.4.1.9.2.1.58.0")<75, "", "CPU over 75%")
Value: oid("1.3.6.1.4.1.9.2.1.58.0")
Unit: % CPU Load
================
The Oid i pulled from some "Cacti" template.

I had the error value set to <50 a few days back, I would get an error report everytime someone started a large file copy across a network link.
only problem i have is the graphs blank for the period where the error vale matches :-(. (any ideas guys?)
The guys in our server team hate me ;-).

The Dude Rocks !!!
