NAME
sa2 - Create a report from the current standard system activity daily data file.
SYNOPSIS
/usr/lib/sysstat/sa2
DESCRIPTION
The sa2 command is a shell procedure variant of the sar
command which writes a daily report in the
sarDD or the sarYYYYMMDD file, where
YYYY stands for the current year, MM for the current month and DD
for the current day. By default the report is saved in the
/var/log/sysstat
directory. The
sa2
command will also remove reports more than one week old by default.
You can however keep reports for a longer (or a shorter) period by setting the
HISTORY
environment variable. Read the
sysstat(5) manual page for details.
The sa2 command accepts most of the flags and parameters of the sar command.
The sa2 command is designed to be started automatically by the cron command.
EXAMPLES
To run the sa2
command daily, place the following entry in your root crontab file:
5 19 * * 1-5 /usr/lib/sysstat/sa2 -A
This will generate by default a daily report called
sarDD in the
/var/log/sysstat
directory, where the
DD parameter is a number representing the day of the month.
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.
