by name.
* pidstat: Update variables type to be consistent with recent
3.x kernels.
* sadc/sar/sadf: The standard daily data files may now be
named saYYYYMMDD instead of saDD. Option -D has been added
to sar and sadc to tell them to write to data files under the
name saYYYYMMDD.
* sadc/sar/sadf: Take into account alternate locations for
standard daily data files.
* sa1 and sa2 scripts updated: Don't create a tree of directories
any more if HISTORY is greater than 28. Use saYYYYMMDD
data files instead.

SA_DIR (directory where sa and sar files are located) and
ZIP (compression program to use).
* Make sysstat init script source the functions library
* Fix possible buffer overflow.

in datafiles. The number of CPU is displayed in the RESTART
messages.
* DTD and XSD documents updated.
* [Tomasz Torcz]: Add systemd timer units replacing cronjobs.
* [Mike Kazantsev]: Fix output of sadf -j with file-utc-time present.
* [Peter Portante]: sa2 script now also catches 'xz' compressed
files as well.

* Added new --enable-copy-only option to configure script.
This option may be useful when creating sysstat package to
make sure that files are only copied to $DESTDIR and that
no service is activated (eg. for distro using systemd).
* pidstat: Add a new metric to pidstat I/O statistics:
per-task block I/O delays.
* Take $DESTDIR variable into account when installing sysstat
service used by systemd.
* sadf -H, sadf -j and sadf -x now also display the file
creation time.
* Use sizeof() instead of hardcoded size values.
* pidstat manual page updated.
* Cosmetic fixes.
* NLS updated.
2013/11/03: Version 10.2.0 - Sebastien Godard (sysstat <at> orange.fr)

get a SIGINT signal during the first interval of time.
* [Alexander Troosh]: mpstat: Take into account the highest
processor number in mpstat output.
* Rearrange options displayed by sar -h (upper case option
should be displayed before its lower case counterpart).

* New metric added to sar network devices statistics: %ifutil
now gives the network interface utilization percentage.
* Now use a lightweight static library having only the necessary
functions to compile sysstat commands. This results in a
size 25% to almost 45% smaller for some commands.
* [Kevin Johnson]: Rewrite rule for librdstats.a in Makefile
to allow parallel execution.
* [Peter Schiffer]: Fix wrong permissions for data file created
by sa1 script when HISTORY is greater than 28.

be displayed with option -F.
* DTD and XSD documents updated.
* Code cleaned: Removed several unused constants from header files.
* Sysstat command options can now be 'collapsed' (grouped) when
not followed by an argument. So it's now possible for example

receives SIGINT (crtl/c).
* sar now stops and displays its average stats when it receives
SIGINT (crtl/c).
* pidstat now displays task's UID for all tasks.
* pidstat: -U option added. This option tells pidstat to display
the username of the task instead of its UID. When this option is
followed by a user name, then only tasks belonging to the
specified user are displayed by pidstat.
* pidstat manual page updated.
* Now use sigaction() instead of signal() for signals handling
to avoid portability problems.
* FAQ updated.

could display weird values if the thread group leader terminated.
* Header line displayed by sar, iostat, mpstat, pidstat and
sadf -H now includes the number of CPU.
* Use the correct word TGID instead of PID with pidstat -t.
* mpstat now displays stats for all interrupts, including NMI,
LOC, etc.
* sar and sadf now check that CPU activity is available in file.
* iostat's option -t now always displays the date and the time.
* Added option "--disable-documentation" to ./configure. Using
this option prevents documentation files (including manual
pages) from being installed.
* iconfig script updated. Now ask the user for documentation
and isag script installation.
* Manual pages updated.
* NLS updated. Indonesian and Chinese (traditional) translations
added.
* README-nls file updated.
* Makefile updated: There is now a dedicated target to install
or uninstall NLS files
* FAQ updated.
* CREDITS file updated.
* Code cleaned.
2008/07/14: Version 8.1.5 - Sebastien Godard (sysstat <at> orange.fr)
* Added virtual machine time accounting to "sar -u ALL" and
mpstat (%guest).
* pidstat has also been updated to be able to display time
spent in virtual machine for a task, and for a task and all
its children.
* Option -S added to sar: This options tells sar to display
swap space utilization. Option -r now only displays memory
utilization.
* Added %swpcad to sar -S (percentage of cached swap memory
in relation to the amount of used swap space).
* Added kbcommit and %commit to sar -r (amount and percentage
of memory needed for current workload).
* sadf -x now distinguishes between options -r and -R.
* sadf command updated to take into account new fields
(%guest, %swpcad, etc.)
* [Ivana Varekova]: iostat now displays the total number of
operations per second in the NFS report.
* Fixed iostat so that %system (percentage of CPU utilization
that occurred while executing at system level) also takes
into account time spent to service interrupts and softirqs.
* Added a missing header line for activities with multiple
outputs displayed by sar (eg. sar -rR ...).
* Makefile updated: There is now a dedicated target to install
or uninstall manual pages.
* Manual pages updated.
* Code cleaned.
* XSD and DTD documents updated.
* isag script updated.
2008/06/22: Version 8.1.4 - Sebastien Godard (sysstat <at> orange.fr)
* sar can now collect and display all CPU fields with its new
option "-u ALL". sadf has also been updated to be able to
display them.
* mpstat can now display per-CPU interrupts statistics with its
option "-I CPU". This was a feature available in sar that was
removed in previous sysstat version.
* mpstat uses now a separate option ("-I SUM") to display the
total number of interrupts for each processor.
* Option -A added to mpstat. This switch tells mpstat to display
all possible activities.
* NFS v4 support added to sar -n NFS(D). When both NFS v3 and
NFS v4 are used, stats from NFS v3 and NFS v4 are added
together [DEBIAN bug#434442].
* Code cleaned: mpstat, iostat and pidstat now use the common
functions from rd_stats.c to read CPU stats from /proc/stat;
Computing extended disk statistics (service time, etc.) is now
done in one place (common function used by iostat, sar, sadf).
* All sysstat commands are made consistent with how parameters
are interpreted: "COMMAND <interval>" now generates a report
continuously, "COMMAND <interval> 0" causes an error,
"COMMAND 0" displays a report since system startup
[DEBIAN bug#475707].
* Changed XML output for processes and context switches displayed
by sadf -x to be consistent with output from sar.
* mpstat and sar manual pages updated.
* isag script updated.
* FAQ updated.
* DTD and XML Schema updated.
* NLS updated.
2008/05/25: Version 8.1.3 - Sebastien Godard (sysstat <at> orange.fr)
WARNING: Daily data files format has changed, and is *not*
compatible with the previous one! [0x2170]
* sar, sadc and sadf heavily modified. It is now easier to add
(or remove) activities since sar and sadc have been rewritten
in a non-monolithic way with a generic design architecture.
* Option -c removed from sar. Task creation and context switch
activities are now merged and available with option -w.
* sar no longer displays interrupts per processor statistics.
This feature will be included in mpstat in next sysstat version.
* Option -S added to sadc. This option replaces previous options
-I or -d, and is used to select activities that should be
collected and saved in file. It is even possible to
select each activity collected by sadc.
* Format of data files created by sar/sadc heavily modified.
In some cases, it is now possible to add or remove activities
while keeping a compatible format that can be read by a previous
or future sysstat version.
* sadf now only displays activities that have been explicitly
selected.
* sar now checks that devices displayed by option -d are whole
devices (and not partitions) using sysstat.ioconf configuration
file. If this file is not found in its default directory, then
sysstat looks for it in current directory.
* gettextize entire usage() messages so that translators have
free scope to act.
* DTD and XML Schema updated.
* Manual pages updated.
* Crontab samples updated.
* FAQ updated.
* Code cleaned.
2008/03/16: Version 8.1.2 - Sebastien Godard (sysstat <at> orange.fr)
* [Ivana Varekova]: iostat now displays read and write operations
per second in the NFS report.
* [Tomas Mraz]: sadc now retries to write its buffers when the
write() call has been interrupted by a signal.
* Use setbuf() call instead of fflush() to indicate that data
should not be buffered to stdout.
* Option -h added to sadf. Used with options -d or -D, it
indicates that all activities should be displayed horizontally
on a single line of data.
* sadf -d and sadf -D now display the list of fields for easier
data reading.
* sadf and iostat manual pages updated.
* NLS updated: Chinese (simplified) translation added, other
translations updated.

sadf -x also displays machine architecture.
* DTD and XML Schema documents updated.
* The number of processors was not properly calculated on
machines where a directory named cpuidle was present in the
/sys/devices/system/cpu directory [GENTOO bug# 207886].
