I've done this on the cluster and host level with a small hack. Note
that this DOES NOT WORK with the latest trunk code, as I've not fully
updated it to use the Dwoo template engine. It probably won't work on
your system either. :) However, you should be able to get the gist of
it.
Note that there are two different ways of "choosing" what graphs to
show. One a a looong set of if/else blocks. The other (more elegant,
IMO) uses regexes. Take your pick....
