Seth has described one method to go about it. I would also strongly recommend you take a look at gmetad-python which is a Python re-write of gmetad and the code exists in our development branch:
http://sourceforge.net/apps/trac/ganglia/browser/trunk/monitor-core/gmetad-python One of the cool things of the re-write is that it has a plugin interface much like the DSO interface for gmond, meaning how you deal with metrics data collected by gmetad can be implemented via plugins. Storing the metrics data in RRD format is implemented as a plugin so you could simply write your own plugin to store the data in MySQL, cassandra or even flat files. Another cool thing you can do is send alerts if a particular metric has reached a certain threshold. Please try it out if you are interested. We are aiming to make an release which includes gmetad-python in the near future, so please stay tuned.
