Help with data source script not executing

[notmike]

Found a script in the forum I want to try here http://forums.cacti.net/about30771.html

Tested the script from command line and was everything was successful. Added as a data query on one of my routers and shows "data query returns 0"
Retested the script as cacti user and found that was not able to create ssh keys, so I fixed that but still no data. It doesnt show up as a data source

Debugging poller I don't see the script actually executing.
Looking at verbose output for data query gives me the below. So the XML seems to be executing but I can't validate the perl script is actually being executed. Turned on debug logging but I don't show any output for this query. How else can I debug to determine why this script isn't running?

thanks
