Hobbit Graphs by cron

Hi all,

I want to generate some hobbit / xymon graphs every day. I have been trying to get the following url to work but it keeps failing.

Please can some one tell me (I am not a web master) how to get an image generated such as image01.jpg.

http://www.docum.org/foswiki/bin/view/Xymon/DebugGraphs

I created a file in the cgi directory, add the config and my url. made it executable and ran it using the command but I get.

bbcmd hobbitgraph2.cgi > /tmp/graph.out 2009-06-25 14:44:25 Using default environment file /usr/libexec/hobbit/server/etc/hobbitserver.cfg

Thanks
