Read the file config.txt in the doc directory.  Search for "external"
and for "gauge".

Write a script that returns the number of lines in your file, make sure
it has the correct format for mrtg as described in the config.txt file.

You don't write what your OS is so I have to assume it is linux:

Something like:

----cut here----
LINES=`wc -l < myfile.txt`
echo $LINES
echo 0
uptime|sed 's/load average.*$//'
----cut here----

And then as target for mrtg:

----cut here----
Target[myfile]: `/the/full/path/to/above/script`
Options[myfile]: gauge,growright
----cut here----

with the usual other stuff.
