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

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

SYNOPSIS
       /usr/lib64/sa/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  /var/log/sa/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
	      restarts from 0.

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/lib64/sa/sa1 1200 3 &

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