SA2(8) Linux User's Manual SA2(8)
sa2 - Create a report from the current standard system activity
daily data file.
/usr/local/lib64/sa/sa2
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/sa 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.
To run the sa2 command daily, place the following entry in your
root crontab file:
5 19 * * 1-5 /usr/local/lib64/sa/sa2 -A
This will generate by default a daily report called sarDD in the
/var/log/sa directory, where the DD parameter is a number
representing the day of the month.
/var/log/sa/sarDD
/var/log/sa/sarYYYYMMDD
The standard system activity daily report files and their
default location. YYYY stands for the current year, MM for
the current month and DD for the current day.
