Hi Amber:

The starting point is the top command, there is also the 'sar' command and vmstat. You can man each of these for details. The very best is a tool called Glance but alas it's not free.
You can load a trial version from your Application CD's. Extended memory is better referred to as virtual memory (sometimes as swap) in UNIX.

Hi Amber:

For memory utilization metrics, I'd use 'vmstat' (see: man 'vmstat'). For CPU loading metrics, I'd use 'uptime' (see: man 'uptime') and 'sar' (see: man 1M 'sar'). Take a look at 'sar -q' and 'sar =u' particularly.

If you have 'glance' you have an excellent performance monitor. If you don't, you can install a trial version from your Application CDROM(s). 'glance' is worth its license fee!
