Hi! What is the best way to get accurate measurements of the amount of real and virtual memory sizes used by a process, and how does one monitor swapping? Basically, I'd like to track the swapping and memory usage on my system, an AlphaServer 2100 running Digital Unix 3.0B. We're also about to upgrade to an AlphaServer 4100 running DU 4.0D, so I'd like to know if the suggested method will work on this platform as well. I tried using the ps -A -o rssize, vsize command, and passed it through an awk script, but the figures I got don't seem to match what I *know* to be my total physical and virtual memory. I suspect that I misunderstand my server's manpages on the ps command. Thanks for your help.
