Another option will be to have each module able to print some usable
configuration. I am attaching some patch from a quick hack that I wrote
for the multidisk plugin to output a usable .conf file. Maybe extending
the mudule api with a metric_autoconf function so you can do a gmond -t
modulename > modulename.conf (or something similar) is a good idea.
It can get you going for simple setups where you just need to collect
all available metrics.
