Hi managers,
I have a question from a user about % MEM, I found in
http://www.tru64unix.compaq.com/docs/base_doc/DOCUMENTATION/V51A_HTML/ARH9GB
TE/TITLE.HTM
information of % MEM, but how can i explain about of 4.0 or 12.7 in % MEM ?,
how can to calculate it ?
Saludos
Julio Ramos
P.D.
This information is in chapter 6
6.3.2 Displaying Memory by Using the ps Command
To display the current state of the system processes and how they use
memory, enter:
# /usr/ucb/ps aux
Information similar to the following is displayed:
USER PID %CPU %MEM VSZ RSS TTY S STARTED TIME COMMAND

The ps command displays a snapshot of system processes in order of
decreasing CPU usage, including the execution of the ps command itself. By
the time the ps command executes, the state of system processes has probably
changed.
The ps command output includes the following information that you can use to
diagnose CPU and virtual memory problems:
Percentage of CPU time usage (%CPU). [Return to example]
Percentage of real memory usage (%MEM). [Return to example]
