For memory utilization, you can use the ciscoMemoryPoolTable objects from the CISCO-MEMORY-POOL-MIB. For example:

ciscoMemoryPoolUsed

ciscoMemoryPoolFree

ciscoMemoryPoolLargestFree

For CPU utilization, you can use the cpmCPUTotalTable objects from the CISCO-PROCESS-MIB. For example:

cpmCPUTotal1min

cpmCPUTotal5min

Each of these objects are in a table, so there may be multiple instances. I recommend you walk each table on the device so you can get a feel for what each object represents.

Hi,

I will doing the same for generating the graph thro MRTG. But i need the OID for the same.

I dont know how to get that.

Hi,

Thro the URL i got these OID's

.1.3.6.1.4.1.9.9.48.1.1.1.5 Memory Used

.1.3.6.1.4.1.9.9.48.1.1.1.6 Memory Free

.1.3.6.1.4.1.9.9.48.1.1.1.7 Memory Largest Free

.1.3.6.1.4.1.9.9.109.1.1.1.1.4 CPUTotal 1min

.1.3.6.1.4.1.9.9.109.1.1.1.1.5 CPUTotal 5min

I have configured the same on mrtg and my cpu utilization is working fine but my memory utilization graph is not growing. Pls let me know that this OID for memory is correct.

Hi ,

I suggest walking through the MIB using snmpwalk tool and get the OID's and their exact values directly from the device .This way you will get the exact value that will be accepted by the device .

Joe Clarke Thu, 09/11/2008 - 06:38

As I said, you need to walk these objects on the device to get the specific instances which can be polled. These OIDs cannot be polled directly. Once you have the OIDs with their instances, you can add those to MRTG to get your graphs.
