I have been trying to get the TCH perl scripts that are included with the mrtg application to work, but they continue to return zero's. There are no error messages, and the community string is correct and entered in all of my chassis'. I have tried both the dualt1.pl and the hiperdsp.pl script and both behave the same. It is obvious I am missing something but the docs are slim. What could it be? How should I go about finding the problem?
