For Solaris Xymon computes memphysused = memphystotal - memphysfree

"memphystotal" is what is reported as "Memory size: xxx Megabytes" in 
client data. You did not show us the value, so I assume it is 16160 M as 
in the web page.
"memphysfree" is the fifth column of memory output in client data.


So with the last data you gave us this gives:
memphysused = 16160 - 2435600/1024 = 13781.48 MB

This value rounded up gives 13782 MB with is what the web page says.
