First off, changing the amount of disk capacity has no effect on the swap
requirements for your system (unless you didn't allocate the proper 
amount of swap when you initially setup your system).  

Placing the following commands into a crontab for "sys" will get you
a nightly report of all of the system activity on you system.  Feel
free to modify the arguments as you feel fit (be sure to read the 
sar and sadp man pages).

	0,15,30,45 * * * * /usr/lib/sa/sa1
	30 23 * * * /usr/lib/sa/sa2 -ubycwaqvmpr

The first line takes samples every 15 minutes and the second line
prints out the nightly report.
