display virtual memory usage
Hello,
I am looking for a set of commands to monitor virtual memory on a tru64 server:
I have come up with:
vmstat
monitor
then I also use this on other systems:
UNIX95=1 ps -e -o vsz,ruser,pid,args | sort -rn |more
I read the man page and see vsz is Process virtual address size, is this telling me this is the virtual memory usage for the proc?
appologies for my tru64 ingnorance and any other tools I can use would be great.
Thanks
Chris.

Re: display virtual memory usage
fwiw, you don't need the UNIX95 for ps in Tru64.
The -o is a (tru64) standard extention with many options.
vss is indeed Virtual memory,
but rssize (RSZ) for the Resdent Size is often more critical. That's the 'real' memory used.
You also want to look at 'top', and for longer term data collection always think about 'collect' first.

Re: display virtual memory usage
Besides collect, probably swapon -s is another command that may help. Check also the swap allocation mode kernel parameter (swap_eager).
