MRTG will ask rateup to do the work.  You can call rateup yourself,
this is undocumented (as far as I know) and it will take you some
time to figure it out.  I did this, quite some time ago, but do not
remember exactly how.

If you want to figure it out yourself, here's how I did it:

- rename the original rateup command (for instance: rateup.orig)
- create a script that will call the original rateup with all of
  the arguments you give to the script.  This script also logs
  the commands with parameters to a file
- wait a couple of minutes, until MRTG has updated the graphs
- restore the original configuration:
   - rename your script (for instance: rateup_script)
   - rename the original rateup command back to rateup

Now have a good look at the logged output.  It will show what
parameters are given to rateup when mrtg wants it to create
