I made several of them for our environment, both from the default Hobbit 
provided tests (apache %CPU) and from our custom NCV data (mysql 
queries/sec, memcached %hits, etc), simply by copying one of the multi 
graph defs and adjusting the variable extracted from the appropriate rrd 
file.  I've found that the multi graphs only work when you are graphing 
one variable per host, so you can't do something like RAM & Swap for 2 
hosts in a single chart.

For example, this def should allow you to see the %CPU apache is 
consuming on your web servers, if you are using the apache test in 
bb-hosts.  Hope it helps.
