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 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/sysstat/README.Debian file for details.

FILES

   /var/log/sysstat/saDD
   /var/log/sysstat/saYYYYMMDD
          The standard system activity daily data files and their  default
          location.   YYYY stands for the current year, MM for the current
          month and DD for the current day.
