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


I have this problem too.

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 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;

I am using the same OID I found on MRTG website (http://oss.oetiker.ch/mrtg/doc/mrtg-nt-guide.en.html) 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:

Target[traget_CPU]:[email protected]

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.

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.
