SA2(8) Linux User's Manual SA2(8)
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 di-
rectory. 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 repre-
senting 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.De-
bian file for details.
