NAME

       sa1 - Collect and store binary data in the system activity daily data file.

SYNOPSIS

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

DESCRIPTION

       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 command 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 command.

OPTIONS

       --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.

EXAMPLE

       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/sysstat/README.Debian file for details.

FILES

       /var/log/sysstat/sadd
              Indicate  the  daily  data  file,  where  the dd parameter is a number representing the day of the
              month.
