Want to monitor Router CPU Utili. using SNMP.

Hi All,

I have a hub-spoke network of 55XX/6XXX series switches. From a single point I want to monitor every switche's CPU Utilization.

I checked one util called Getif. Any other (better) suggestions from the group.

Regards,

Vijayendra K. S.

Hi,

The Getif can't collect the catOS's cpu and you can serch on cisco web site.

IOS CPU oid:1.3.6.1.4.1.9.2.1.56

I like to use MRTG (http://people.ee.ethz.ch/~oetiker/webtools/mrtg/).

A couple of tricks for CPU utilization:

- Private MIB objects need a full specification (1.3.6.1.2....).

- Default scaling can be overridden with fixed scales (also useful

to prevent misleading usage graphs).

- Use the "gauge" option to plot value rather than change.

Here is a sample config for a 7206 router (watch the line wraps):

Target[gw.sample.net_cpu]: 1.3.6.1.4.1.9.9.109.1.1.1.1.5.1&1.3.6.1.4.1.9.9.109.1.1.1.1.5.1:public@gw.sample.net:

A great utility is called MRTG:

http://people.ee.ethz.ch/~oetiker/webtools/mrtg/

It's a great tool and provides a single web page where you can see all your graphs at once. It's a bit tricky to set up but there are lots of resources on the Internet that can be of assistance.

HTH

I confirm the (great!!) value of MRTG.

here are some further info from Cisco:
