[hobbit] BBWin Virtual Memory

[Shawn Heisey]

I use Hobbit 4.2 as my production server, and I don't have any Windows 
clients pointing at Xymon right now.  I am currently using BBWin in 
local configuration mode because it's going to be a sizable time 
investment to switch.  I am waiting until I am ready to replace the 
production server and upgrade to Xymon before changing to central config 
mode.  I hope that these possible differences don't make my installation 
so different as to make what I'm saying useless.  If so, hopefully 
someone who knows will speak up.

The virtual (shows up as "actual" on the graph), as you have noticed, is 
useless.  On all of my systems, it shows 32 used out of 2047.  The 
physical memory (shows up as "real" in the graph) is actual physical 
memory, but it's *mostly* a useless figure as well.  The page value 
(shows up as swap in the graph) is the one that seems to really matter.  
It is the overall usage of both physical memory and the pagefile.  Be 
aware that if the ratio of real memory to pagefile on your systems 
varies widely (as it does in my network), you will end up needing very 
different alarm thresholds for each of your systems.  Adjusting that 
ratio is the only way I've found to bring parity, but the biggest 
problems tend to be on the older systems, which usually don't have 
enough disk space to accomodate a change.
