sysstat: System performance tools for the Linux operating system...
--
(C) 1999-2015 Sebastien GODARD (sysstat <at> orange.fr)

The latest version of sysstat can always be found on my web site at:

http://pagesperso-orange.fr/sebastien.godard/

See the CHANGES file to know the new features/improvements/bug fixes added
in this release of sysstat.

You can also track sysstat development on GitHub:

https://github.com/sysstat/sysstat

and clone its public repository with:

git clone git://github.com/sysstat/sysstat


INSTALLATION
------------

The sysstat utilities are a collection of performance monitoring tools for
Linux. These include mpstat, iostat, tapestat, cifsiostat,
pidstat, sar, sadc, sadf and sa tools. 

The first stage is to configure sysstat for your system:

	./configure

You can set several variables and parameters on the command line.
Please enter "./configure --help" to display them.
There is another way to configure sysstat instead of entering "./configure":
this is the Interactive Configuration script (iconfig) which will ask you
for the value of the main sysstat variables and parameters.
Enter "./iconfig" then answer the questions or enter Return to accept
the (sane) default values. For yes/no questions, please answer 'y' or 'n'
(without the quotes): It is case sensitive! You can also enter '?' to get
a help message that will explain the meaning of each variable or parameter.

The next stage is to build the various binary files. Enter:

	make

Then log in as root and enter:

	make install

(see next section to know the files that are installed).
That's all!

Of course tell me if there are any problems. This is the only way I can improve
'sysstat'. Please also remember to read the FAQ included in this package.

Patches and suggestions for improvements are always welcome!
Send them to (sysstat <at> orange.fr).

sysstat may also install some links in ${RC_DIR}/rc[0146].d/ directory
if chkconfig is used.

MISCELLANEOUS
-------------

The sysstat commands are only front-ends to the kernel proc filesystem...
They cannot display statistics that Linux does not
provide, nor can they be more accurate than Linux is.
The sysstat package no longer supports 2.4.x and older kernels.
Note that all kernels do not necessarily have all the statistics that
sysstat commands can display, depending on their version or their
configuration options.

It has been designed with National Language Support (NLS) in mind, using
the GNU gettext package (available at http://www.gnu.org).
sysstat has been translated into several languages.
Anyway you are welcome if you want to make other translations available ;-)
Please read the README-nls file in the nls directory before.
