SA1(8)                        Linux User’s Manual                       SA1(8)




NAME

       sa1  -  Collect and store binary data in the system activity daily data
       file.


SYNOPSIS

       /usr/lib/sa/sa1 [ interval count ]


DESCRIPTION

       The sa1 command is a shell procedure variant of the  sadc  command  and
       handles  all  of the flags and parameters of that command. The sa1 com-
       mand collects and store binary data in the /var/log/sa/sadd file, where
       the  dd  parameter  indicates  the  current day. The interval and count
       parameters specify that the record should be  written  count  times  at
       interval  seconds.  If  you  do  not specify these parameters, a single
       record is written.

       The sa1 command is designed to be started  automatically  by  the  cron
       command.



EXAMPLES

       To  create  a daily record of sar activities, place the following entry
       in your root or adm crontab file:

       0 8-18 * * 1-5 /usr/lib/sa/sa1 1200 3 &



FILES

       /var/log/sa/sadd
              Indicate the daily data file, where the dd parameter is a number
              representing the day of the month.
