Actually, you can.
We have an arrangement where we have several clusters arranged in
several grids all reporting into one machine. We use unicast from each
machine to a

We have a cluster with more than 4T of memory. Ganglia (3.0.4) won't
show that on the graphs, although if you visit the physical view it
seems to have the correct number. If you restart all the gmonds, the
summary memory graph looks like a sawtooth; ramping up to 4T and
dropping suddenly to z
I have 3.0.4 installed and mostly working properly. We have lots of
hosts, so the rrds are on tmpfs. I have a grid-of-grids configuration,
with separate gmetad's running for each grid, all on the same host. The
server in question is pretty beefy; it's a Sun T2000; typically has a
load averag
.3 on solaris 9, apache 1.3.27, php 4.3.1. I've
verified that you can indeed connect to 127.0.0.1:8651 and get
appropriate data...PHP works for other apps, although it's not used
very extensively here.
