sa1

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 com-
       mand collects and stores binary data in  the  current  standard  system
       activity daily data file.

       The  standard  system  activity  daily  data  file is named saDD unless
       sadc's option -D is used, in which case its name is  saYYYYMMDD,  where
       YYYY  stands  for the current year, MM for the current month and DD for
       the current day. By default  it  is  located  in  the  /var/log/sysstat
       directory.

       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/sys-
       stat/README.Debian file for details.

              location.   YYYY stands for the current year, MM for the current
              month and DD for the current day.
