Its working fine (Im using the current cvs version) altough I still see bogus 
memory values for my java process(es) (e.g. Total memory usage (incl. children): 
608.7% [385072kB])

I had to tweak the generated Makefile a bit:

Great to hear. One of my next questions would have been something like "how can 
I monitor the total memory usage of my system".

Making this required doesn't allow you to e.g. use a binary or unmodified script 
directly (Just as an example (I know monit already implements ping): If returned 
event type is optional, one could directly use "ping -q -w 5 -c 1 my.server.com").
