If I run c:\mrtg\perl\bin\perl.exe c:\mrtg\mrtg\bin\mrtg-pnsclient.pl -H 172.30.1.204 -v MEMUSE from the command line it connects and shows me two lines of numbers and it reports Nagios query agent version 0.4 and when I call the config file it runs without any errors. Here is the entry in the config file for mem usage.

It's possible that you don'thave MaxBytes set high enough.

Try running the mrtg-pnsclient.pl script from the command line, as defined in the .cfg file, and see what the values output are. If they are larger than the MaxBytes number, then MRTG will store them as UNKNOWNs as they will be out of range. Alternatively, make the MaxBytes setting much larger and see if the line starts to appear (although you'd possibly need to have 'routers.cgi*UnScaled[ezwf]: none' then)
