SA2(8)								Linux User's Manual							    SA2(8)

NAME

       sa2 - Write a daily report in the /var/log/sysstat directory.

SYNOPSIS

       /usr/lib/sysstat/sa2

DESCRIPTION

       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. The sa2 command handles all of the flags and parameters of the sar command.

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

EXAMPLES

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

       5 19 * * 1-5 /usr/lib/sysstat/sa2 -A &

       This will generate a daily report called /var/log/sysstat/sardd It will also remove reports more than one week old.

   Debian note
       The Debian sysstat package  has	already  placed  such  an  entry  in  your  system  crontab.   Please  refer  to  the  /usr/share/doc/sys-
       stat/README.Debian file for details.

FILES

       /var/log/sysstat/sardd
	      Indicate the daily report file, where the dd parameter is a number representing the day of the month.
