Pls someone help me to add cpu and memory utilization of a 3750 L3 switch into the MRTG output. and also advice how to get the OID of the said device. many thanks..

With the help of SNMP you can add the utilization. But all you have to do is "walk the SNMP tree" to find out the correct MIB OID's. From the walk, you can narrow down the CPU fairly easily enough.

Thanks for the response from you.

I'm not that much good in SNMP and kindly advice how to do a "SNMP walk" in order to get the OID in to the MRTG.
