sa2 - Write a daily report in the /var/log/sysstat directory.
The sa2 command is a shell procedure variant of the sar command which writes a daily report in the /var/log/sysstat/sardd file, where the dd parameter indicates the current day. It 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 command. The sa2 command is designed to be started automatically by the cron command.
To run the sa2 command daily, place the following entry in your root crontab file: 5 19 * * 1-5 /usr/lib/sysstat/sa2 -A & This will generate a daily report called /var/log/sysstat/sardd. 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.
/var/log/sysstat/sardd Indicate the daily report file, where the dd parameter is a number representing the day of the month.
