        To begin gathering <application>Sysstat</application> history

        <application>Sysstat</application> utilities via cron must have write
        access to this location.

      <para>
        Below is an example of what to install in the crontab. Adjust the
        parameters to suit your needs. Use <command>man sa1</command> and
        <command>man sa2</command> for information about the commands.
