The free memory amount you're likely to get will be misleading....especially
if you're coming from a non-aix world. AIX boxes tend to show frighteningly
low amounts of free ram, because every scrap that's not needed for
processes, gets used for file cache.

Subject: how to calculate memory utilization on a AIX box
Hi all,
I have to give a system resources utilization report to my management,
on a weekly basis.
I have written some scripts to collect data. For CPU utilization I'm
using sar and for memory utilization I'm using vmstat.
I'm just using the free mem column and getting an average value. Then
calculating the percentage from total real memory of the system.
My question:
1. Is it correct what I'm doing for memory utilization?
2. Can someone give a URL name where I can get more information on how
to calculate memory utilization on AIX boxes?
Regards,
Habeebulla Suhail
