2. how to generate daily report from "sa2 " peocess?
Thanks.

I suggest reading the man pages on sar, and associated functions.
sar -f /var/log/sa/sa22 would process the data for the 22nd, see what files you have available in /var/log/sa/ ... my system seems to be keeping 18 days worth.
sa2 is used to create the daily reporrt files described above. If you want to create a daily report in a specific format, you'll probably want to write your own script that you invoke from crontab
chkconfig sysstat on service sysstat start
