Sounds like you want another front end to rateup.  This is probably the
best approach to your problem.

Step by step:

1) find out what MRTG is telling rateup to do (how, when and why)
2) do this yourself (from your script)

Easy, no?

You could for instance write a wrapper around rateup, one that logs
the commands given to it before it starts the real rateup.  Let MRTG
run a couple of times, using different types of targets and you should
be able to figure out what all these parameters do.  When in doubt,
read the source.
