The Sysstat package contains utilities to monitor system performance and usage activity. Sysstat contains the sar utility, common to many commercial Unixes, and tools you can schedule via cron to collect and historize performance and activity data.

Install Sysstat by running the following commands:
make config &&
make
Now, as the root user:
make install
make config: Runs the interactive configuration process. The first question prompts you for an "Installation directory". Reply with /usr, as this is equivalent to Autoconf's --prefix=/usr parameter to configure. For all other prompts, you may press Enter to accept the (very sane) defaults.
To begin gathering Sysstat history information, you must add to, or create a privileged user's crontab. The default history data location is /var/log/sa. The user running Sysstat utilities via cron must have write access to this location.
Below is an example of what to install in the crontab. Adjust the parameters to suit your needs. Use man sa1 and man sa2 for information about the commands.
# 8am-7pm activity reports every 10 minutes during weekdays 0 8-18 * * 1-5 /usr/lib/sa/sa1 600 6 & # 7pm-8am activity reports every hour during weekdays 0 19-7 * * 1-5 /usr/lib/sa/sa1 & # Activity reports every hour on Saturday and Sunday 0 * * * 0,6 /usr/lib/sa/sa1 & # Daily summary prepared at 19:05 5 19 * * * /usr/lib/sa/sa2 -A &
Ensure you submit the revised crontab to the cron daemon.
At system startup, a LINUX RESTART message must be inserted in the daily data file to reinitialize the kernel counters. This can be automated by installing the /etc/rc.d/init.d/sysstat init script included in the blfs-bootscripts-6.0 package using the following command:
make install-sysstat
reports CPU statistics and input/output statistics for devices and partitions.
reports individual or combined processor related statistics.
collects, reports and saves system activity information.
collects and stores binary data in the system activity daily data file. It is a front end to sadc designed to be run from cron.
writes a summarized daily activity report. It is a front end to sar designed to be run from cron.
is the system activity data collector, used as a backend for sar.
