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



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

SYNOPSIS
       /usr/lib64/sa/sa1 [ --boot | 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 command collects and stores 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 no arguments are given to sa1 then a single record is written.

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


OPTIONS
       --boot This option tells sa1 that the sadc command should be called without specifying the
              interval and count parameters in order to insert a dummy record, marking  the  time
              when the counters restarts from 0.


EXAMPLE
       To  collect  data (including those from disks) every 10 minutes, place the following entry
       in your root crontab file:

       0,10,20,30,40,50 * * * * /usr/lib64/sa/sa1 1 1 -S DISK


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