[mrtg-developers] Getting error from MRTG when running externalscript

[Scott S. Heath]

Actually I wrestled with that for a while. There is a new line char in
the file and I found it easier to leave in then chomp it.

If queueFile equals 200, this script will output:

"2000
0
CopyQueueLength"

whereas you probably want:

"200
0
0
CopyQueueLength
"

Notice: you have three lines with two linefeeds, I wrote four lines with
four linefeeds.

Don't know if that is the problem or not, I just noticed.
