NAME         top

       sa2 - Create a report from the current standard system activity daily
       data file.

SYNOPSIS         top


DESCRIPTION         top

       The sa2 command is a shell procedure variant of the sar command which
       writes a daily report in the sarDD or the sarYYYYMMDD file, where
       YYYY stands for the current year, MM for the current month and DD for
       the current day.  By default the report is saved in the /var/log/sa
       directory.  The sa2 command will also remove reports more than one
       week old by default.  You can however keep reports for a longer (or a
       shorter) period by setting the HISTORY environment variable. Read the
       sysstat(5) manual page for details.

       The sa2 command accepts most of the flags and parameters of the sar

       The sa2 command is designed to be started automatically by the cron

EXAMPLES         top

       To run the sa2 command daily, place the following entry in your root
       crontab file:

       5 19 * * 1-5 /usr/local/lib64/sa/sa2 -A &

       This will generate by default a daily report called sarDD in the
       /var/log/sa directory, where the DD parameter is a number
       representing the day of the month.
