+
+.SH SYNOPSIS
+.B /usr/lib/sa/sa2
+
+.SH DESCRIPTION
+.RB "The " "sa2 " "command is a shell procedure variant of the " "sar"
+command which writes a daily report in the
+.IR "sarDD " "or the " "sarYYYYMMDD " "file, where"
+.IR "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
+.I /var/log/sa
+directory. The
+.B 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
+.B HISTORY
+environment variable. Read the
+.BR "sysstat" "(5) manual page for details."
+.PP
+.RB "The " "sa2 " "command accepts most of the flags and parameters of the " "sar " "command."

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

+command daily, place the following entry in your root crontab file:

+.IR "sarDD " "in the"
+.I /var/log/sa
+directory, where the
+.IR "DD " "parameter is a number representing the day of the month."
