( I tried to mail this, but it bounced......)


The manual page for SADC is included in the SAR(1M) manual page
in the System Administrator's Reference Manual. (The is also a SAR(1)
page in the User Reference Manual, but this is for the SAR reports)
(Please no flames on where things are in the manual. That is why
the permuted index exists.)

SAR(1M) also gives a couple of examples how to use the sa1 and sa2 commands
(both in /usr/lib/sa) It includes a few examples.

The sadc command must be restarted periodically to collect
data over a specified time. The manual pages  show how to
set up a crontab entry to sample over 20 minute intervals.

To try it, invoke "/usr/lib/sa1 1200 3".
The 1200 specifies a sample every 20 minutes (20 * 60 = 1200),
the 3 tells it to take 3 samples (so that the command covers 1 hour)

If these commands (sa1, sa2, sadc) are truly not on the system
(they should all be in /usr/lib/sa) send me mail and I will find out
where you should be able to find them. (be sure to let me know what
release of Operating System you have (output from uname -a).)
