sa1



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 com-
       mand 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.
