Setting Line Speed - Best Practice?

[pshankland]

I am currently monitoring some WAN links and the utilisation on these links. I have only one slight problem which is that some of the links are reporting |query_ifSpeed| as the wrong value and therefore giving back the wrong utilisations.

The graph attached is from a Cisco 2620 Router which is connected to a 256k line but because the interface I am monitoring is the serial link it is reporting at 1544000bps when the link is actually 256000bps.

I have created a new CDEF so that instead of bringing back the |query_ifSpeed| value it simply uses 256000. I then copied the Graph Template that I had modified so that I could use different templates for different devices, but this is where I have got stuck. I don't know the best way to go from here. Any suggestions?

Thanks.

Pete.

I think I have worked it out:

1) Duplicated the existing Graph Template and modified it
2) Modified the 'SNMP - Interface Statistics' Data Query
3) Added in the new modified Graph Template
4) Added the Graph Template to the Device

Look ok to everyone?

Thanks
