sadc

PURPOSE

     Provides a system activity report package.

SYNOPSIS
     /usr/lib/sa/sadc [ interval num ] [ outfile ]

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

     /usr/lib/sa/sa2

DESCRIPTION

     The operating  system contains a number  of counters that
     are incremented  as various  system actions  occur.  They
     include the following:

     o   System unit utilization counters
     o   Buffer usage counters
     o   Disk and tape I/O activity counters
     o   TTY device activity counters
     o   Switching and system-call counters
     o   File-access counters
     o   Queue activity counters
     o   Inter-process communications counters

     The sadc  command and  the sa1  and sa2  shell procedures
     sample, save and process this data.

     Note:  These commands only report on local activities.

       sadc

     The sadc command, the data collector, samples system data
     num times  every interval  seconds.  It writes  in binary
     format to outfile  or to the standard output.   If you do
     not specify interval or num, a special record is written.
     This facility is used at  system startup to mark the time
     when the counter restarts from zero.

       sa1

     Use the shell procedure sa1, a variant of sadc to collect
     and store binary data in the file /usr/adm/sa/sadd, where
     dd is the day of the month.  The interval and num parame-
     ters specify that the record  should be written num times
     at interval seconds.  If you do not specify these parame-
     ters, one record is written.  You must have permission to
     write in the directory /usr/adm/sa to use this command.

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

       sa2

     Use  the  shell  procedure  sa2, a  variant  of  the  sar
     command,   to   write   a  daily   report  in   the  file
     /usr/adm/sa/sardd.  See  "sar" for  a description  of the
     flags.

     The sa2  command is designed to  be started automatically
     by the cron command.
