SA1(8) Linux User's Manual SA1(8)
NAME
sa1 - Collect and store binary data in the system activity daily data file.
SYNOPSIS
/usr/lib/sysstat/sa1 [ 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 store 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 you do not specify these parameters, a single record is written.
The sa1 command is designed to be started automatically by the cron command.
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
/var/log/sysstat/sadd
Indicate the daily data file, where the dd parameter is a number representing the
day of the month.
