NAME
sa1 - Collect and store binary data in the system activity daily data file.
SYNOPSIS
/usr/lib/sysstat/sa1 [ --boot |intervalcount]
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/sysstat/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.
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/sysstat/sa1 1200 3 &
Debian note
The Debian sysstat package has already placed such an entry in your system crontab.
Please refer to the
/usr/share/doc/sysstat/README.Debian
file for details.
FILES
