7 file.

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 current standard system
16 activity daily data file.
17
18 The standard system activity daily data file is named saDD unless
19 sadc's option -D is used, in which case its name is saYYYYMMDD, where
20 YYYY stands for the current year, MM for the current month and DD for
21 the current day. By default it is located in the /var/log/sa directory.
22
23 The interval and count parameters specify that the record should be
24 written count times at interval seconds. If no arguments are given to
25 sa1 then a single record is written.
26
27 The sa1 command is designed to be started automatically by the cron
28 command.

32 --boot This option tells sa1 that the sadc command should be called
33 without specifying the interval and count parameters in order to
34 insert a dummy record, marking the time when the counters
35 restart from 0.
