[mrtg] Re: MRTG and PacketShaper.

[Paul C. Williamson]

Hi,

I see two immediate problems with your config, without even 
getting to the actual error (which I'll address in a sec...)

You need two OIDs for MRTG to work.  Period.  If you try it with 
any number of OIDs that is not 2, including, but not limited to:
1,3,4,5 and 6, MRTG will not function.  (I suddenly had a flashback 
to Monty Python's The Holy Grail and the sacred egg grenade...).

Second, if you are going to use up resources to do a LoadMib, at 
least use them in the target call.  If you are going to use the OID, 
don't waste the resources to load the MIB.

As for your error, have you tried to grab the value of the OID from 
the command line?

Hi,

We need to graph traffic statistics from a PacketShaper which uses the
following OID for traffic classes:

1.3.6.1.4.1.2334.2.1.4.2.1.37.XXXX where XXXX is the traffic class
identifier.

Using the following Mrtg.cfg file:

>From the above, MRTG is looking for OID: 1.3.6.1.2.1.2.2.1.10.1.X which is
not applicable to the PacketShaper, we need it to poll OID
1.3.6.1.4.1.2334.2.1.4.2.1.37.X.

Any idea how we can make MRTG fish for the required variables and not its
(Cisco) defaults?
