SA1(8)                                 Linux User's Manual                                 SA1(8)



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

SYNOPSIS
       /usr/lib/sysstat/sa1 [ 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 store  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 you do not specify these parameters, a single record is written.

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


EXAMPLES
       To  create a daily record of sar activities, place the following entry in your root or adm
       crontab file:

       0 8-18 * * 1-5 /usr/lib/sysstat/sa1 1200 3 &

   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.
