sa1 and sa2

Hi all, does anyone know what is the relationship between sa1 and sa2? Apparently both have to be included to make reporting work. If you include only 1, let's say sa2, the file is created but there's no content inside. Can someone shed some light and also provide examples of sa1 and sa2? Thanks a whole bunch.

sa1(8)							    BSD System Manager's Manual 						    sa1(8)

NAME

     sa1 -- Generate a system activity daily data file.

SYNOPSIS

     /usr/lib/sa/sa1 [t n]

DESCRIPTION

     The sa1 command is a shell script used to invoke the system activity data collector, sadc.  The binary sample data is collected at intervals
     t seconds apart, in a loop n times.  The binary sample data is written to the standard daily data file, /var/log/sa/sadd where the dd repre-
     sents the current day of the month.

     sa1 is intended to be started by cron.

EXAMPLE CRON ENTRY

     # Starting at 8am collect system activity records
     # every 20 minutes for 12 hours
     # 20 minutes = 1200 seconds
     # 12 hours with 3 samples each hour = 36 loops

     0 8 * * 1-5 /usr/lib/sa/sa1 1200 36

     # After the 12 hour period,
     # collect a system activity report

     30 20 * * 1-5 /usr/lib/sa/sa2 -A

FILES

     /var/log/sa/sadd  Default daily activity file that holds the binary sampling data.  dd are digits that represent the day of the month.
