Well in my `hobbit-clients.cfg' there is already an entry like this.

   PROC "%hobbitd.*" TRACK=hobbitd

It already counts the total number of %hobbitd and label it as hobbitd.
How about let it count the total amount of rss and pcpu as well for that
process
and just create two more rrds?

It won't be really inaccurate because it gives you a graphical
representation of
what the `ps' is telling you. Plus it could be GAUGE type data I guess.

Atleast it will give you some trend of how a process has been behaving. Even

though it may not do the pmap -x calculation but it sure will give you
pointing
fingures to some heavy processes

I bet you lot of hobbit community members would like to see ps graphs
builtin
to hobbit app


Another problem with this is identifying what a process is. A

Thanks for the feedback to all of my feature requests. It is very kind of
you.
