/usr/lib/sysstat/sa1 [ --boot | interval count ]

       The sa1 command is a shell procedure variant of the  sadc  command  and
       handles  all  of the flags and parameters of that command. The sa1 com-
       mand collects and stores binary data in the /var/log/sysstat/sadd file,
       where  the  dd  parameter  indicates  the current day. The interval and
       count parameters specify that the record should be written count  times
       at  interval  seconds.  If  no arguments are given to sa1 then a single
       record is written.

       The sa1 command is designed to be started  automatically  by  the  cron

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

       To collect data (including those from disks) every  10  minutes,  place
       the following entry in your root crontab file:

       0,10,20,30,40,50 * * * * /usr/lib/sysstat/sa1 1 1 -S DISK

   Debian note
       The  Debian  sysstat  package  has already placed such an entry in your
       system   crontab.    Please   refer    to    the    /usr/share/doc/sys-
       stat/README.Debian file for details.

              Indicate the daily data file, where the dd parameter is a number
              representing the day of the month.
