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 command collects and stores binary data in the /var/log/sa/sadd file, where the dd param-
       eter  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.


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.
