It sounds like you've inherited a system.  I hope 
this isn't a system you installed from scratch.
The data comes from the disk-larrd.pl collector 
running on the system.  You should have a trends 
button where all the graphs show up.  What 
version of BB are you running?  The server sounds like 
it has the LARRD option enabled if you are getting 
a graph in the service itself.  The way it selects the 
graph to display is based on what service you have
selected.  I'll explain more, but it sounds like the larrd 
installation isn't quite working right.

Try this list or Craig Cook's excellent BB config manual 
on deadcat.  To really understand how the graphs 
show up, check out Tobi Oetiker's RRDTool, upon which 
LARRD is based.

It all depends on which client you are speaking of.  
Windows, linux, unix, precompiled, package, rpm, etc.?

I have systems with 16gb ram and it reports it fine under 
solaris.
