This page has news,
information, documentation and links software for the <b>sysstat</b>
utilities that I created for Linux. The <b>sysstat</b> utilities are a
collection of performance monitoring tools for Linux. These include <code>sar</code>,<font
 face="courier, monospace">mpstat</font>, <code>iostat</code> and <code>sa</code>
tools. </p>

 <font size="2"><b><i>Tuesday 			June 8,
2004</i><br>
      </b>Sysstat
			5.0.5 released (stable version).<br>
Maybe the last stable version 			before the beginning of a new
development series. This one fixes a 			bug in the binary RPM file,
where symlinks to sysstat script were 			wrong in the /etc/rc.d
directories. It also get rid of 'mojibakes' 			that sar and mpstat
could have displayed with some locales 			(especially ja_JP).<br>
 <font size="2"><b><i>Thursday 			May 20,
2004</i><br>
      </b>Sysstat 			5.0.4 released
(stable version).<br>
Small but important fixes in 			this release : some of them concern the
sysstat shell script 			called on system reboot. A bug introduced in
version 5.0.1 			prevented it from working properly (LINUX RESTART
messages could 			no longer be added automatically to daily data files
on system 			restart).<br>
  
 <b><i>Wednesday 			April
7, 2004</i><br>
      </b>Sysstat 			5.0.3 released
(stable version).<br>
Various fixes and improvements 			added in this version, among which
the major one concerns the 			handling of 'unsigned long long' counters
which are beginning to 			appear in the kernel (see kernel 2.6.5 for
example). Also note 			that the isag tool has been upgraded and it
should now really fix 			the small temporary file vulnerability. <br>

			March 10, 2004<br>
      </b>Sysstat 			5.0.2 released
(stable version).<br>
      <font color="#000000">OK, 			sysstat 5.0.2 is ready for download
at last. A few bugs have been 			fixed in this version. But above all, <font
 color="#ff0000">iostat 			can look for its extended statistics in the
/proc/partitions file 			again </font>if available. /proc/partitions
support had been 			removed in sysstat 4.1.3 in favor of sysfs included
in 2.6 			kernels. Its support has been added again here because many
			production servers are still using 2.2.x and 2.4.x kernels 			today.</font><br>
  
			February 27, 2004<br>
      </b>Sysstat 			5.0.2 will be
released Wednesday, March 10. <font color="#0000ff">With
			this version, iostat will be able again to get its extended
			statistics from /proc/partitions on 2.2 and 2.4 kernels ! </font><br>
  
			February 2<sup>nd</sup> , 2004<br>
S</b>ysstat 			5.0.1 released (stable
version).<br>
The main improvement in this 			version is the addition of option -L to
sadc, enabling it to lock 			its output file to prevent multiple
instances from writing to it 			at once. Beside this, do not hesitate
to try this version with 			recent 2.6 kernels to make sure it is
really stable.<br>
  
			December 15, 2003<br>
      </b>Good 			news : From now on,
you have access to the source packages of old 			sysstat versions. This
may be useful for some people, for example 			those who are still
running old kernels and want extended 			statistics information with
iostat. See the download 			section.<br>
  
			November 9, 2003<br>
      <font color="#ff0000">Sysstat 			5.0.0 released (stable version)</font></b><span
 style="font-style: normal;"><br>
Yes... 			You read it: the new sysstat version 5.0.0 is now available
on 			your favorite web site ;-) It has new improvements again, and
even 			the documentation has been enhanced. So, just try it and you
will 			feel better! And if you find any bugs left, well, tell 			me...<br>
  
			September 28, 2003<br>
      </b>Sysstat 			4.1.7 released
(development version)<br>
OK. Here is the first 			sysstat version which should be <font
 color="#0000ff">100% 			compliant with 2.6 Linux kernels</font>. This
version uses 			/proc/diskstats in addition to sysfs to get statistics
for 			devices. Also several new statistics were added to sar (page
			faults, swap cached, devices stats....) whereas other ones
			considered not really useful were removed.<br>
I'm waiting now for 			your feedback so that sysstat 5.0.0 can be
released soon. 			Enjoy...<br>
  
			August 20, 2003<br>
      </b>Sysstat 			4.1.6 released
(development version)<br>
      <font color="#000000">This 			version contains another bunch of
fixes and optimizations (iostat, 			sar, mpstat). See the changelog
file for details. Oh, and option 			-F was added to sadc to force the
creation of its daily data file. 			This is particularly useful to
avoid the &laquo;&nbsp;Invalid 			system activity file&nbsp;&raquo;
error messages you get when the 			format of those files changes.<br>
PS: I hope that next sysstat 			release (4.1.7), planned for october,
will be fully kernel 2.6 			compliant. My goal is to start again with a
stable series (5.0.x) 			before the end of the year.</font><br>
  
			July 22<sup>nd</sup>, 2003<br>
      </b>Sysstat 			4.1.5 released
(development version)<br>
      <font color="#000000">Several 			important fixes are included in
this release : sar -x / -X now 			work again (a buglet in sysstat 4.1.4
made these options 			unavailable). Also a bug, introduced in the 4.1.x
series, made 			some LINUX RESTART messages to not be displayed by sar
; this is 			fixed here. Last, sar -P now works properly on machines
with more 			than 32 processors.</font><br>
  
			June 30, 2003<br>
      </b>Sysstat 			4.1.4 released
(development version)<br>
      <font color="#000000">Various 			minor bugfixes are included in
this version, like the way sar 			handles overflow with interfaces
counters. Option &laquo;&nbsp;-x 			SUM&nbsp;&raquo; was removed from
sar, since the calculation of 			the total number of faults made by the
system was rather tricky. 			Also the code was greatly cleaned, and
sysstat should now be 			really lighter than before as a consequence. </font><br>
  
			May 8, 2003<br>
      </b>Sysstat 			4.1.3 released
(development version)<br>
OK. This is the first 			version of sysstat to take advantage of the <font
 color="#ff0000">sysfs 			filesystem</font>, included in recent,
cutting-edge Linux kernels. 			Thus iostat should now be fully
compliant with 2.5/2.6 kernels. 			But as a consequence, iostat will no
longer look for statistics in 			the /proc/partitions file. <font
 color="#0000ff">Those who need to 			display extended statistics with
iostat while still using an older 			2.4 kernel must use sysstat 4.1.2
(or sysstat 4.0.7). </font><font color="#000000">With 			regard to
sar, it has not been updated to use sysfs : I would 			rather wait for
2.6 kernels to be available...</font><br>
  
			January 23<sup>rd</sup>, 2003<br>
      </b>Sysstat 			4.1.2 released
(development version)<br>
Lots of small and not so 			small changes in this release. Among
others, sar -q now also 			displays load average for the past 15
minutes, and option -P has 			been added to sar to display stats on a
per processor basis. 			Because of this, sar syntax has changed a
little : sar -U ALL is 			replaced by sar -u -P ALL (or simply sar -P
ALL), and sar -I PROC 			is replaced by sar -I SUM -P ALL.<br>
  
			January 2<sup>nd</sup>, 2003<br>
      </b>Sysstat 			4.1.1 released
(development version)<br>
This new year starts with 			a new development series for sysstat. The
result will be a set of 			commands that will work with cutting edge
Linux kernels (2.5.x and 			above). Sysstat 4.1.1 is the first version
in this series. It 			includes I/O wait support by all the commands of
			sysstat.<br>
  
			November 13, 2002<br>
      </b>Sysstat 			4.0.7 released
(stable version)<br>
Small changes in this version : 			1) the data for midnight time
(00:00:00) is now saved in the daily 			data file before sar/sadc
rotates it ; 2) mpstat -P can now be 			used even on UP machines.<br>
NB: A new development series (4.1.x) 			is to begin soon to take into
account newer 2.5/2.6 			kernels.<br>
  
			August 4, 2002<br>
      </b>Sysstat 			4.0.6 released
(stable version)<br>
The main changes in this 			release concern the mpstat command. A few
bugs affecting it on 			big-endian architectures have been fixed.<br>
  
			May 12, 2002<br>
      </b>Sysstat 			4.0.5 released
(stable version).<br>
Various fixes were added in 			this version, among which the most
important one concerns service 			times and average wait times
displayed by iostat -x. Also sar -H 			is now able to display its
timestamps in local time or in UTC 			(this was expected for long now).
Other softwares related to 			sysstat (isag, and the new sargon shell
script) are now available 			in the contrib directory included in
sysstat source 			package.<br>
  
			April 7, 2002<br>
      </b>Sysstat 			4.0.4 released
(stable version).<br>
iostat is now able to display 			disk I/O activity in kilobytes per
second with 2.4.x kernels 			(option -k). No need to use option -x any
more to get this!. A 			file giving answers to frequently asked
questions (FAQ) is now 			included in sysstat package. Last but not
least a few fixes were 			added to sar, and sysstat is now translated
into Russian.<br>
  
			January 27, 2002<br>
      </b>Sysstat 			4.0.3 released
(stable version).<br>
In this version, iostat is now 			able to display disk I/O activity in
kilobytes per second when 			option -x is used. Also sysstat has been
translated into italian, 			and a few potential segmentation faults
have been fixed.<br>
  
			September 22<sup>nd</sup>, 2001<br>
      </b>Sysstat 			4.0.2 released
(stable version).<br>
After a well deserved break, 			sysstat is back with its 4.0.2 version.
This one includes a few 			bug fixes, in particular with IA64 machines,
and new features like 			the database friendly option -H added to sar.
Also the 			configuration procedure has been improved and sysstat is
now 			translated into Norwegian. Translators are still wanted anyway
			(see note from Friday March 9 below)!<br>
  
			June 24, 2001<br>
      </b>Sysstat 			4.0.1 released
(stable version).<br>
The previous release of 			sysstat (4.0.0) appeared to be quite stable.
There is a new 			version anyway which fixes a few things, among which
a security 			hole and a compile problem with some distro.<br>
  
			April 8, 2001<br>
      </b>Sysstat 			4.0.0 released
(stable version).<br>
The new stable version of 			sysstat is now available ! Check out the
download page to get it. 			This version is fully compatible with Linux
2.4 of course. Enjoy 			!<br>
  
			March 9, 2001<br>
      <font color="#ff0000">TRANSLATORS 			WANTED !</font> </b><span
 style="font-style: normal;">Sysstat was 			designed with National
Language Support in mind. I am now looking 			for people willing to
translate sysstat messages in their own 			language. I especially need
a spanish translator, since the 			spanish translation is no longer
maintained. Other languages, such 			as italian, swedish, russian,
polish, etc. are welcome. If you are 			interested and feel good
enough, please read the <font face="courier, monospace">README-nls</font>
			file included in <i>sysstat</i> package, and get in touch with 			me!<br>
  
			March 8, 2001<br>
      </b>Sysstat 			3.3.6 released
(development version).<br>
New features have been 			added here to the <b>sar</b> command :
ability to report on load 			averages, queue length, and devices. Also
new paging statistics 			have been added. And the usual set of bug
fixes. I hope to release 			the final stable version of <i>sysstat</i>
at the beginning of 			April (sysstat 4.0.0).<br>
  
			February 11, 2001<br>
      </b>Sysstat 			3.3.5 released
(development version).<br>
This version contains an 			<b>iostat</b> command that takes full
advantage of Stephen 			Tweedie's kernel patch to display extended I/O
statistics. 			Sysstat-3.3.5 also includes for the first time a tool to
plot the 			data stored in a daily data file : this is the <b>isag</b>
command 			(Interactive System Activity Graph).<br>
  
			January 26, 2001<br>
      </b>Sysstat 			3.3.4 released
(development version).<br>
This is the first version 			of sysstat which is fully compliant with
Linux 2.4.x kernels! The 			bulk of the work has concerned the <b>iostat</b>
command. A few 			bugs with the <b>sar</b> command have also been fixed.<br>
