i need to monitor the CPU Load for this switch;can i know the MIB OR OID To use it in my cfg file?



Re: cpu load thr MRTG

I did not find the MIB for this switch in the Cisco MIB locator.

However we use solarwinds and it is able to poll a 3548XL for CPU load.

Will try to find out the OID from the solarwinds database

Hi Ali,

Which Network Management software are you using in the network? I have few customers of mine using the same CPU load montioring with HO Openview Unicenter. They have built in OID's to montior the CPU load for devices.

Hi Amit!

i will monitor the CPU Thought the MRTG;AMIT I Sent u mail plz check it.




Re: cpu load thr MRTG

Hi Ali,

I'm not using 3500 anymore. I use mrtg to monitor cpu, memory and disk of win2k3 and linux servers and cpu, memory, and interfaces of pix firewalls. I use cricket primarily for cisco devices. I'm able to run cricket in windows 2k3.

However, try this for 3500;

Target[hostname.cpu]: .

Re: cpu load thr MRTG

I am using the same OID I found on MRTG website ( check the example at the end of the page. I didn't know that there are different OIDs for CPU for each model. I have different models in my network (6513,4507,3750) and I have configured MRTG to monitor the CPUs of all these model using the same OID:


So far I am getting results from MRTG on CPU usage from all models. So try that OID. Please anyone let me know If I really should be using different OIDs for each model. Thanks.

Re: cpu load thr MRTG

The OID is avgBusy5 from the OLD-CISCO-SYS-MIB. This OID is deprecated, and may not be accurate for all devices. It certainly will not work for CatOS devices. A more current OID is cpmCPUTotal5min ( from the CISCO-PROCESS-MIB. It, too, is deprecated, but it much more universally supported. The best object to use (provided your device is new enough to support it) is cpmCPUTotal5minRev (

There is a big difference between these two objects and avgBudy5, though. The two cpmCPUTotal5min objects are part of a table, and so they will have non-zero instance numbers. Before you can use these objects in MRTG, you will need to figure out which instance to monitor. Typically, the instance you want will be 1 (for example, this will always be 1 on the 3750), but on multi-CPU boxes, you may want to monitor all CPUs. So you should first walk the cpmCPUTotalTable ( to see which CPU instances you can monitor, then configure MRTG accordingly.
