Debugging external commands:

1) make sure mrtg works.  Start with monitoring a regular interface
   and change nothing but the target line thereafter
2) use a dummy script at first that provides dummy output, just to
   test your target line
3) make sure the script used works.  Make sure it works when called
   from mrtg.  Do not assume the PATH is correct, use full path names
   for each and every external command called from the script

Do read faq entry #26 for this information, slightly more verbose.
