Changes:2006/04/23: Version 6.1.2 - Sebastien Godard (sysstat <at> wanadoo.fr)	* Fix incorrect NFS client and server statistics for sar.	* sar can now display stats for newly created processes when	  option -x ALL or -X ALL is used.	* iostat -x was displaying redundant information. It now	  displays amount of data read from or written to devices in	  sectors, kilobytes or megabytes depending on the switch used.	* isag updated to keep up with current sar version.	* sar and mpstat manual pages updated.	* FAQ updated.2006/02/22: Version 6.1.1 - Sebastien Godard (sysstat <at> wanadoo.fr)	  WARNING: Daily data files format has changed, and is *not*	  compatible with the previous one! [0x2168]	* New field added to sar: %steal.	* The size of a long integer in now saved in the header of the	  data file created by sar. This size can be displayed with	  sadf -H.	* Replaced the keyword "FULL" by the keyword "ALL" for sar -n	  to be consistent with remaining options.	* Makefile updated (use implicit rules).	* sar manual page updated.	* CREDITS and FAQ files updated.2005/11/28: Version 6.0.2 - Sebastien Godard (sysstat <at> wanadoo.fr)	* New field added to mpstat and iostat: %steal.	* sar updated to take into account cpu steal time.	* Off-by-one error in ioc_conv which was corrupting device names	  on 64-bit architecture [Debian bug #334305].	* Binary RPM package now installs a sample crontab in /etc/cron.d.	* Makefile updated (remove sysstat.cron.* during make clean -	  new target added: sysstat.crond.sample).	* sar now checks exit code from dup2() system calls.	* Option -V now only displays sysstat version number.	* NLS updated.	* FAQ updated.	* Manual pages updated.2005/06/25: Version 6.0.1 - Sebastien Godard (sysstat <at> wanadoo.fr)	* Fixed a memory leak in ioconf parsing functions used by sar	  and iostat.	* sar now displays its statistics to STDOUT in addition to saving	  them into the file when option -o has been entered on the	  command line.	* sar now recalculates number of system items (network interfaces,	  disks, serial lines, etc.) when a file rotation happens.	* Make sar -b work again when used without option -d.	* Small changes so that sysstat can be compiled with gcc-4.0.1.	* sysstat updated so that it may be installed on Slackware.	* sar manual page updated.	* CREDITS file updated.	* Code cleaned.2005/05/14: Version 6.0.0 - Sebastien Godard (sysstat <at> wanadoo.fr)	  WARNING: Daily data files format has changed, and is *not*	  compatible with the previous one! [0x2167]	* Additional fields added to sar -y (TTY statistics). sar, sadf	  and DTD updated.	* sar -d now only reports for used devices (devices with non zero	  statistics).	* Stricter sadf syntax checking: various output formats are now	  mutually exclusive.	* Stricter iostat syntax checking: -k and -m options are now	  mutually exclusive.	* iostat: option -m is now taken into account even when	  displaying extended statistics.	* Fixed a bug that prevented iostat from displaying stats about	  devices that were unknown in sysstat.ioconf file.	* iostat might display bogus sectors values when the corresponding	  kernel counters had overflown. This is now fixed.	* "sadf datafile -- -A" should also display individual interrupts	  if available in datafile.	* Fixed a bug that prevented sar -x from displaying stats about a	  process if it was after the first 256 processes in the process	  list.	* Manual pages updated.	* sa1 script always uses option -d in crontab.	* sysstat.ioconf device configuration file updated.	* NLS updated.	* FAQ and CREDITS files updated.	* Code cleaned.2005/02/25: Version 5.1.5 - Sebastien Godard (sysstat <at> wanadoo.fr)	* -x option added to sadf: it is now able to display the contents of	  a sar datafile in XML. The corresponding DTD (Document Type	  Definition) is included in the sysstat package.	* Small code change so that sysstat may be compiled with gcc-4.0.	* A few typos fixed in formulas used by sadf to display stats 	  on machines where HZ<>100 (typos appeared in sysstat 5.1.4).	* Fixed a bug in the stats displayed by sar -d.	* Removed a false workaround in iostat: better show that the kernel	  is buggy rather than display a value that seems correct but which	  is actually not...	* Fixed sar -i option which might not select records at the specified	  interval on machines with multiple processors.	* NLS updated and cleaned. Do no longer translate fields names (sar,	  iostat, etc.). Changed nb_NO.po and nn_NO.po files to nb.po and	  nn.po.	* Bug fixed in spec file: when installing sysstat i586 RPM package,	  sa1 and sa2 scripts were pointing to the wrong sadc location.	* Now sar and sadc display the magic number when they meet an	  invalid system activity file.	* sadf manual page updated.	* sysstat RPM spec file is now included in source package.	* Code cleaned.	* FAQ, Makefile and CREDITS files updated.2005/01/02: Version 5.1.4 - Sebastien Godard (sysstat <at> wanadoo.fr)	  WARNING: Daily data files format has changed, and is *not*	  compatible with the previous one! [0x2166]	* NFS client and server statistics added to sar.	* sar -d now only reads stats for devices (and not partitions)	  from /proc/partitions. (This is what it was already doing with	  /proc/diskstats).	* Display routines from sadf merged, so that -ppc and -db	  always output the same values.	* sadf updated to handle NFS statistics.	* sadf can now display the header of a data file (option -H).	* Define MAX_BLKDEV in ioconf.h if non-existent in <linux/major.h>.	* sar now looks for sadc in one directory only, specified at	  compile time. Moreover it is now possible to have two different	  sysstat versions installed: sar knows where its sadc counterpart	  is located.	* sapath.in removed. SADC_PATH is defined in CONFIG file.	* sar and sadf manual pages updated.	* sysstat.ioconf file updated.	* Fixed a bug in i386 RPM package, where sadc location was not	  consistent with that of sar. Spec file updated.	* Makefile updated.	* NLS updated.	* Various cosmetic changes (code and manual pages). Code cleaned.	* FAQ and CREDITS files updated.2004/11/22: Version 5.1.3 - Sebastien Godard (sysstat <at> wanadoo.fr)	  WARNING: Daily data files format has changed, and is *not*	  compatible with the previous one! [0x2165]	* Option -p added to sar: It enables sar (and also sadf) to	  display device names as they appear in /dev.	* sysstat.ioconf support added.	* New fields added to sar -d (more disk activities displayed):	  avgrq-sz, avgqu-sz, await, svctm, %util.	* sadf updated to handle new disk activities.	* I/O and transfer rate statistics as displayed by sar -b are	  available whatever the version of the kernel is (i.e. even on	  recent kernels).	* Disk stats are read by sadc from /proc/stat only if they cannot	  be read from /proc/{partitions,diskstats}.	* sadc: Some variables declarations moved around.	* sar manual page updated.	* Added workaround for EMC PowerPath driver bug to enable iostat	  to display proper device name.	* Makefile updated: Use $@ and $< everywhere; 'make {iostat,mpstat}'	  work again; Create object files before linking; Removed unused	  IOS_DFLAGS variable; Use DESTDIR variable everywhere; Create	  libsysioc.a; Install sysstat.ioconf.	* NLS updated.	* README and CREDITS files updated.2004/11/05: Version 5.1.2 - Sebastien Godard (sysstat <at> wanadoo.fr)	* sar -d now also uses /proc/partitions to get its data.	  From now on sar -d looks in the following files in that order:	  /proc/diskstats, /proc/partitions, /proc/stat.	* sadc writes disks data to file only if -d option is explicitly	  set on the command line.	* sadc now reads individual interrupts data from /proc/stat only	  if -I option was entered on the command line.	* 'sar -A' is now equivalent to 'sar -bBcdqrRuvwWy -I SUM -I XALL	  -n FULL -P ALL' (i.e. individual interrupts are also included	  in activities).	* Option -m now tells iostat to display statistics in megabytes	  per second instead of blocks per second.	* Make history (number of days to keep log files) configurable	  in /etc/sysconfig/sysstat file, which is used by sa2 script.	* Now use Vixie cron to launch sadc when possible.	* sadc, sa1 and sa2 may now be installed in another directory	  than ${PREFIX}/lib/sa. This is useful on 64-bit systems where	  the proper directory should be ${PREFIX}/lib64/sa.	* When uninstalling sysstat, always delete sysstat script,	  config file and links in /etc tree. Also always delete	  Vixie cron entry.	* sysstat script now returns real exit code.	* sar/sadc: Stricter syntax checking for -x and -X options use.	* sysstat "*.sh" files renamed in "*.in".	* Makefile updated.	* sadc and sar manual pages updated.	* NLS updated.	* FAQ updated.	* CREDITS and README files updated.2004/10/09: Version 5.1.1 - Sebastien Godard (sysstat <at> wanadoo.fr)	  WARNING: Daily data files format has changed, and is *not*	  compatible with the previous one! [0x2164]	* sar now reads CPU data, number of context switches, number	  of sectors and total number of interrupts as 64-bit unsigned	  values. It also reads the number of running processes as	  unsigned long instead of unsigned int.	* sadf - System activity data formatter command added.	* Options -h and -H removed from sar. "sar -h" is replaced by	  "sadf -p", and "sar -H" is replaced by "sadf -d". Read sadf	  manual page, as its syntax is a bit different from that of sar.	* Common code for sar and sadf moved to sa_common.c file.	* pid_stats members don't need to be aligned since these stats	  are not written to daily data files. Packing them saves some	  memory on 32-bit architectures.	* No longer indicate that -x and -X are possible options for sadc.	  They are only useful when used as options for sar, not sadc.	* Minor buffer overrun fixed in iostat.	* Updated CPU header for iostat and mpstat: CPU used while executing	  at the system level is displayed as '%system' by iostat (like sar)	  and as '%sys' by mpstat.	* sadf manual page added. Other manual pages updated.	* Updated the GPL notices (the address of the FSF was wrong).	* Makefile updated.	* NLS updated.	* README, FAQ and CREDITS files updated.2004/08/09: Version 5.0.6 - Sebastien Godard (sysstat <at> wanadoo.fr)	* The value for file-sz reported by sar -v was a number of free	  handles, and not a number of used ones! This is now fixed (and	  this is really now a number of _used_ file handles).	* Now ask during config stage for the directory where sadc will	  be located. This may be useful for some systems where sadc	  needs to be installed in a specific location (e.g. on 64 bit	  s390 systems, the proper directory should be /usr/lib64/sa).	* sa1 script updated: Use '-' to specify current daily data file	  instead of guessing its name using current date.	* NLS updated: be consistent with GNU gettext standards.	* iostat manual page updated.	* FAQ updated.	* Makefile updated.	* CREDITS file updated.2004/06/08: Version 5.0.5 - Sebastien Godard (sysstat <at> wanadoo.fr)	* Timestamp is no longer limited to 11 characters. This should	  avoid problems with somes locales (for example Japanese locale,	  where 'mojibake' used to be displayed by sar and mpstat sometimes).	* Fixed a bug in sysstat RPM spec file (symlinks to sysstat	  script were wrong in /etc/rc.d directories).	* sar now checks parameters for options -n, -s and -e more	  aggressively.	* NLS updated: Japanese translation added.	* Various typos fixed in several files (manual pages, README, etc.)	* CREDITS file updated.2004/05/20: Version 5.0.4 - Sebastien Godard (sysstat <at> wanadoo.fr)	* When trying to lock file, sadc now checks for both EWOULDBLOCK	  and EAGAIN error codes to be portable.	* sar could sometimes display a line whose time stamp was greater	  than the limit set by -e option. This is no longer possible.	* The sadc command in sysstat.sh script had to be enclosed in	  quotes to work when called via 'su -c'.	* The sysstat.sh script was sending the output of sadc command	  to stdout instead of the standard system activity file. This	  is now fixed.	* Outfile must now be explicitly set to "-" for sadc to use the	  standard system activity file.	* FAQ updated.	* iostat manual page updated. Typo fixed in sadc manual page.	* Fixed the "Save picture" option of isag script.2004/04/07: Version 5.0.3 - Sebastien Godard (sysstat <at> wanadoo.fr)	* iostat now reads the number of sectors in /proc/diskstats or	  from sysfs as 64-bit unsigned values.	* iostat and mpstat now read CPU data and the number of	  interrupts in /proc/stat as 64-bit unsigned values.	* sar uses "%u" instead of "%d" to read unsigned integer	  values _everywhere_.	* sar and sadc are now a little bit more verbose when dealing	  with invalid activity files.	* Network interface name size is now read from include file	  <net/if.h>.	* FAQ polished up.	* Slovak translation added. NLS updated.	* Typo fixed in iostat manual page.	* Makefile and CREDITS file updated.	* isag upgraded to version 1.26 (isag package release 0.81.0).2004/03/10: Version 5.0.2 - Sebastien Godard (sysstat <at> wanadoo.fr)	* iostat will _again_ look for statistics in /proc/partitions if	  available. Too many production servers are still using 2.2.x or	  2.4.x kernels and iostat must be able to display extended stats	  also for them (/proc/partitions support was removed in sysstat	  version 4.1.3). So now, iostat gets its statistics from the	  following sources in that order: /proc/diskstats, sysfs,
