Re: Cisco OIDs

Hi,

I want to monitor my routers using MRTG. Where can i find the OIDs for eg CPU load, latency, for the cisco routers?

Someone mentioned to me SNMPWalk... what's that? anyone care to explain more?

Thanks

MIBs and the corresponding OIDs-> http://www.cisco.com/public/mibs

snmpwalk mean polling the devices via SNMP using a NMS tool/application. If you don't have one, you can use the UCD-SNMP freeware for this.

Can you please exlpain (in short) how do I find the right OID for the value I want?

For example if I want the 5 minute CPU-overall on my Catalyst 4506 I find here:

and in the MIB-file:

that cpmCPUTotal5min gives me this value.

However, where do I go now? In ftp://ftp.cisco.com/pub/mibs/oid/ I can't find the value cpmCPUTotal5min in any file?

Since as far as I understand it MRTG uses the OID to locate the value.

Or did I get it wrong? Or in short, this MRTG example:

# Router CPU load %

Target[cpu.1]:1.3.6.1.4.1.9.2.1.58.0&1.3.6.1.4.1.9.2.1.58.0:public@10.10.10.1

How did they find out that OID?

Try:

Then plugin cpmCPUTotal5min, you will see the OID is .1.3.6.1.4.1.9.9.109.1.1.1.1.5

To translate to the OID, you can use the CCO SNMP Object Navigator Tool:

cpmCPUTotal5min is deprecated, use cpmCPUTotal5minRev instead.
