Ben,
First of all, I apologize for all the errors - that's just lousy coding on my part. Once I get around to rewriting the code and integrating it into Ganglia I'll be sure to keep it cleaner. As for your problem, there are 2 dependencies in this code: php-session and rrdtool 1.2 (or higher) I believe your problem is with the latter - a version of rrdtool (probably 1.0 which ships with SLES9 and RHEL3) that doesn't support VDEF. This isn't a critical part of the code as it's just used to display min/avg/max values. If there's a need I could post a version which works with rrdtool 1.0 as well.
