Hi.  You CAN read from a script file if you have to.  Simply write a small
perl script to read the data from the file (it has to be in some sort of
standard delimited format).  Then you can read each field (as it were) from
each line and assign it to a variable, and as Alex stated then print it to
the screen.

The issue is more of a timing one.  How to coordinate the data output file,
and the script's reading of that file.

I mention this not to dispute Alex (Hi Alex!) but just to let you know that
there are ways to read from a text file and bring it into MRTG in case the
mechanism collecting the data has no other output choices.
