sadc

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

NAME

     sadc -- system activity data collector

SYNOPSIS

     /usr/lib/sa/sadc [-m mode] [t n] [ofile]

DESCRIPTION

     The sadc tool is used to collect cumulative system activity data.	The sample system data is collected at intervals t seconds apart, in a
     loop n times.  The binary sample data is written to ofile if specified.  Otherwise, the binary data is written to stdout.	If the ofile file
     does not exist, it is created, otherwise it is truncated.

     sadc is intended to be used as the engine behind the sar(1) command, and is not typically invoked on the command line.  Two shell scripts,
     sa1 and sa2 are provided to drive the typical sampling, saving, and reporting process.

OPTIONS

     The following options modify the way data is collected by sadc.

     -m mode  Modify the collection of system statistics as specified by mode.	Currently only one mode is supported.

	      PPP      By default, the collection of ppp network interface statistics is turned off.  This is because the number of ppp connec-
		       tions can be very high, causing the raw data file to grow unexpectedly large, especially  when samples are collected at
		       short intervals.  Use the PPP mode to turn the collection back on.

EXAMPLES

     /usr/lib/sa/sadc 15 20 /tmp/sample.out

     This call collects 20 samples at 15 second intervals.  The binary data is written to the /tmp/sample.out file

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.
     /usr/lib/sa/sa1   Shell script used to drive the sar data collection.
     /usr/lib/sa/sa2   Shell script used to drive the sar data reporting.
