Right.  What is nagios ? (don't answer that)

As with *any* data source: just read the documentation and
follow the instructions.  Depending on the data available
and the way it is made available, you can define your target.

You need to read reference.{txt|html} and look at the target
section included therein.  If that doesn't help and you need
help on a specific item, just ask again.

Hint:

Q:Nagios delivers output in text format: "delivered 123 letters"
  How do I program MRTG to take this as input?

I would have answered:

A:Use the external program interface and call nagios from a
  wrapper that removes the text. For example:
  Target[nagios]: `/path/to/nagios parameters  |  cut -f2`
 
but even then I probably would have told you to RTFM.
