13 The sa1 command is a shell procedure variant of the sadc command and
14 handles all of the flags and parameters of that command. The sa1 com‐
15 mand collects and stores binary data in the /var/log/sa/sadd file,
16 where the dd parameter indicates the current day. The interval and
17 count parameters specify that the record should be written count times
18 at interval seconds. If no arguments are given to sa1 then a single
19 record is written.
20
21 The sa1 command is designed to be started automatically by the cron
22 command.

26 --boot This option tells sa1 that the sadc command should be called
27 without specifying the interval and count parameters in order to
28 insert a dummy record, marking the time when the counters
29 restarts from 0.
