Memory utilization graph using RRDTool?

Has anyone ever seen one done? I recently setup lpar2rrd for a project i'm working on. Never noticed that lpar2rrd doesn't have the best memory usage graphs. It's only the whole system but I was wondering is there a way i can add in another webpage that pulls the data from the HMC to collect the Memory usage and use RRDTool to spit out a graphic image for me?

I have passwordless ssh from my machine to my hmc
Lpar2rrd up and running

Any suggestions?

I'm not sure how helpful this is, but we use ganglia to graph memory usage.

The site explicitly says not to use the precompiled version that is linked there, but that's exactly what we've got running. I'm in the process of trying to get apache2.4.2-2 running from the rpms right now but I'm running into an issue with a dependency error (lua5.1) when the package is already installed (I've just emailed the Michael Perzl to try to sort that out)

Seems interesting Thanks for the info! I've been looking on rrdtool's website as well and I've seen some people post up scripts that they used, seems like they would work as well with some slight modifications to work on P Series systems.
