sa2(8)                    BSD System Manager's Manual                   sa2(8)

NAME
     sa2 -- Generate a system activity daily report file.

SYNOPSIS
     /usr/lib/sa/sa2 [-dgpu] [-n mode] [-e time] [-f filename] [-i seconds] [-s time]

DESCRIPTION
     The sa2 command is a shell script used to invoke the system activity reporter sar for purposes of gen-erating generating
     erating the standard default daily report file.  The report file generated is, /var/log/sa/sardd where
     the dd represents the current day of the month.  The sa2 options are the same as those documented in
     sar(1).

     When sa2 runs, it will also remove data and report files, found in /var/log/sa, that are more than one
     week old.

     The sa2 command is intended to be started by cron.

EXAMPLE CRON ENTRY

     # every 20 minutes for 12 hours
