[mrtg] Re: Unknown value

[Matt Katona]

In Cisco Speak it is what MRTG returns as it's identifier for that interface:
Example: A Cisco router at 10.0.0.1 has a serial port known as s5/0 but when you run MRTG's config it will return the serial as 10.0.0.1_1 .. the _1 is the instance that you speak of.

So if you are wanting to monitor the in&out on the NIC of that server, the fastest way is to run an MRTG config on it, figure out what it is (the IP_ADRESS_INSTANCE) and plug that in and see if it will fly. Most of time it works for me. 


If it doesn't work then do what David said and take it for walk!

At a quick guess .0
Try an SNMP walk on the device with that OID.
