The answer depends upon the device and the software version.

IOS old values:

CPU: enterprises.cisco.local.lsystem.avgBusy5.0 .1.3.6.1.4.1.9.2.1.58.0 (see nearby values for other timescales) This might still work for you.

Memory: enterprises.cisco.local.lsystem.freeMem.0 .1.3.6.1.4.1.9.2.1.58.0 obsolete as of IOS 11.1

Newer:

CPU: cpmCPUTotal5sec .1.3.6.1.4.1.9.9.109.1.1.1.1.3.9 (see nearby values for other timescales) I'm not sure if this will work for lower-end models.

Memory: ciscoMemoryPoolUsed 1.3.6.1.4.1.9.9.48.1.1.1.5.1 ciscoMemoryPoolFree 1.3.6.1.4.1.9.9.48.1.1.1.6.1 CISCO-MEMORY-POOL-MIB ... you have to add the used and free to find the total pool size, and add all the pool sizes to find the total device memory size.

Thank you. all i have to do is add the string into MRTG and that will pull the results?

SNMP walk the device starting one node further up, and make note of the entries that are of most interest to you, and put those into MRTG.

In particular, you need to figure out -which- of the memory pools you want to monitor.
