In order to report on historical data, that historical data must exist.
See "man sadc" for example crontab entries.

Alternatively, if you look for current values, you can provide a sampling interval and count.
eg:
Code:
sar -A 5 12

For historical data
1. Uncomment the lines in /etc/init.d/perf file to enable system activity data gathering.
2. /etc/init.d/perf start
3. You will also need to uncomment the sa entries in the system crontab /var/spool/cron/crontabs/sys

Indeed. On Solaris 10 and newer, the command would be:
Code:
svcadm enable svc:/system/sar

Then uncomment the last three lines in the sys crontab and modify them if you need to:
Code:
EDITOR=vi crontab -l sys
...
0 * * * 0-6 /usr/lib/sa/sa1
20,40 8-17 * * 1-5 /usr/lib/sa/sa1
5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A
