If you click through the "client data available" link, you'll see this near
the top:

     [meminfo]
     Total:4084
     Free:6920
     [swapinfo]
     Device          1K-blocks     Used    Avail Capacity
     /dev/da0s1b       4194304        0  4194304     0%


That "Total:4084" is supposed to be the total physical memory in the system,
if I'm reading the freebsd-meminfo.c source correctly.  If you have the
xymon source, that's under the "client" directory.

If that system is supposed to have 8G of memory, I think the kernel may not
be seeing half of it...
