|
|
of processes given on the command line.
|
|
* pidstat -d now displays -1 for I/O stats values when the
|
|
process I/O file cannot be read (permission denied or file
|
|
non existent).
|
|
* mpstat and pidstat commands now exit immediately when they
|
|
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).

|
* Added "prealloc" variable to configure script. This variable
|
|
will determine the size of data files created by sar/sadc.
|
|
* Added xz-compressed target to Makefile.

|
|
|
2013/09/13: Version 10.1.7 - Sebastien Godard (sysstat <at> orange.fr)
|
|
* 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.

|
|
statistics header line.
|
|

|
|
* Filesystems statistics (displayed by sar -F) are now collected
|
|
by sadc only if option "-S XDISK" is used.
|
|
* sar now collects all statistics (including partitions ones)
|
|
when data are saved into a file with option -o.
|
|
* [Yan Gao]: Update iostat manual page: Don't say that device
|
|
saturation occurs when %util is close to 100% for devices
|
|
serving multiple requests simultaneously.
|
|

|
|
2013/06/09: Version 10.1.6 - Sebastien Godard (sysstat <at> orange.fr)

|
be displayed with option -F.
|

|
|
* 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
|
|
to enter 'iostat -px 2 5' since no device name is given to
|
|
option -p. This also concerns pidstat option -U.
|
|
* Fixed type for "memfree" and "intr" elements in XSD document.
|
|
* Removed functions used to count number of items from rd_stats.c
|
|

|
|
* mpstat now takes into account every interrupt per processor
|
|
so that their number adds up to the number displayed for CPU "all".
|
|
* [Peter Schiffer]: systemd unit file couldn't be installed
|
|
because PKG_PROG_PKG_CONFIG macro wasn't expanded in configure
|
|
script. This is now fixed.
|
|
* [Benno Schulenberg]: Fixed a small inconsistency in pidstat
|
|
usage message.
|
|
* Cosmetic fixes in pidstat manual page.
|
|
* NLS updated (de, eo, fi, fr, ja, nb, nl, ru, uk, vi).

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.

|
|
to determine devices real name.
|
|
* Part of 'sadf -H' output was written to stderr instead of
|
|
stdout. This is now fixed.
|
|
* WARNING: sadf: Option '-T' has been renamed into '-U', and
|
|
option '-t' has been renamed into '-T'.
|
|
* sadf: New option -t added. This option tells sadf to display
|
|
the timestamps in the local time of the data file creator

2009/01/11: Version 8.1.8 - Sebastien Godard (sysstat <at> orange.fr)
|
|
* IPv6 support added. A bunch of new metrics have been added to
|
|
sar, enabling the user to display statistics for IPv6 protocol
|
|
family (IPv6, ICMPv6, UDPv6 and network sockets).
|
|
* sadc updated: Option "-S IPV6" tells sadc to collect IPv6
|
|
statistics.
|
|
* sadf command updated to take into account IPv6 statistics.
|
|
* Options -S (for sadc), -P (for mpstat, sar and sadf), -p (for
|
|
iostat and pidstat) and -n and -I (for sar) now accept a list of
|
|
comma-separated arguments.
|
|
* [Ivana Varekova]: Make iostat display statistics for devices only
|
|
(and not partitions) when not using its option -d. This was
|
|
no longer possible with kernels 2.6.25 and later because iostat
|
|
couldn't distinguish between devices and partitions any more.
|
|
* iostat's options -x and -p are no longer mutually exclusive:
|
|
Extended statistics are now available even for partitions with
|
|
recent kernels.
|
|
* iostat was unable to read stats from sysfs for devices who had
|
|
a slash in their names (for example, iostat -p /dev/cciss/c0d0
|
|
didn't work properly before). This is now fixed.
|
|
* [Amir Rapson]: Fixed a bug in iostat where %CPU spent
|
|
servicing hard and soft irq were counted twice. This bug
|
|
was introduced in 8.1.5.
|
|
* DTD and XSD files updated.
|
|
* Manual pages updated.
|
|
* NLS updated. Maltese translation added.
|
|
* CREDITS file updated.
|
|
|
|
2008/11/13: Version 8.1.7 - Sebastien Godard (sysstat <at> orange.fr)
|
|
* Support for SNMP statistics added to sar. Several keywords
|
|
have been added to option "-n". The user can now display
|
|
statistics about IP, ICMP, TCP and UDP network traffic.
|
|
* sadc updated: Option "-S SNMP" tells sadc to collect SNMP
|
|
statistics.
|
|
* sadf command updated to take into account SNMP statistics.
|
|
* sadf -x now also displays number of CPU.
|
|
* DTD and XSD files updated.
|
|
* sar/sadc: Each item (like network interfaces) is now counted
|
|
once.
|
|
* [Eduardo Ferro Aldama]: Option -l added to pidstat. This
|
|
option enables the user to display the whole command line for
|
|
each process.
|
|
* Option -h added to sar. This option displays a short help message.
|
|
* Cosmetic change in sadf -x output for network statistics.
|
|
* sadf -H now displays the real name of each activity saved in file.
|
|
* Fixed some memory leaks detected by valgrind.
|
|
* pidstat, sar and sadc manual pages updated.
|
|
* FAQ updated.
|
|
* NLS updated.
|
|
* CREDITS file updated.
|
|
* Code cleaned.
|
|
|
|
2008/09/30: Version 8.1.6 - Sebastien Godard (sysstat <at> orange.fr)
|
|
* [David Alan Gilbert]: Option -h added to pidstat. This
|
|
option is used to display all activities horizontally on a
|
|
single line.
|
|
* Fixed a bug in pidstat: When pidstat was used to monitor a
|
|
process and all its threads (with pidstat's option -t), it
|
|
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.

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.

* Removed linux/major.h from list of files included in ioconf.c.
|
|
It was actually not used and also prevented sysstat from being
|
|
compiled on GNU/kFreeBSD.
|
|
* Sysstat scripts (sa1, sa2, sysstat) modified to enable the user
|
|
to keep sar data for more than one month.
|
|
* New parameter (COMPRESSAFTER) added to /etc/sysconfig/sysstat.
|
|
It gives the number of days after which sar datafiles must be
|
|
compressed to save disk space.
|
|
* Replaced the word "Device" with "Filesystem" for iostat
|
|
NFS report.
|
|
* iostat manual page updated.
|
|
* Makefile updated: don't use a static list of languages to
|
|
compile NLS files.
|
|
* "make install" now always install sysstat configuration file
|
|
(default location is /etc/sysconfig).
|
|
* FAQ updated.
|
|
* Added my email address when displaying sysstat version.
|
|
* NLS updated.
|
|
|
|
2006/12/03: Version 7.0.3 - Sebastien Godard (sysstat <at> wanadoo.fr)
|
|
* iostat NFS statistics added.
|
|
* iostat manual page updated.
|
|
* Columns "r/s" and "w/s" enlarged for iostat -x.
|
|
* Minor change so that sar -u may fit in 80 columns.
|
|
* NLS updated.
|
|
* CREDITS file updated.
|
|
|
|
2006/10/22: Version 7.0.2 - Sebastien Godard (sysstat <at> wanadoo.fr)
|
|
* Hotplug CPU support added to sar and mpstat
|
|
* Use /sys to count the number of available processors.
|
|
/proc/stat is used for that only if /sys is not found.
|
|
* sysstat DTD updated.
|
|
* sysstat spec file updated (gettext is now required).
|
|
* NLS updated: Swedish translation added.
|
|
* Manual pages updated.
|
|

|
2006/09/17: Version 7.0.1 - Sebastien Godard (sysstat <at> wanadoo.fr)
|
|
* Use now sysconf() function to get the size of a memory page
|
|
instead of using header file <asm/page.h>.
|
|
* The time specified with sadf options -s and -e is now always
|
|
considered as given in local time. sadf output is now really
|
|
consistent with that of sar.
|
|
* Fixed a bug in the SREALLOC() macro which was causing sar to
|
|
exit unexpectedly with this message: "realloc: Success".
|
|
* Try to better guess when a stats title line has to be displayed
|
|
by sar.
|
|
* Makefile updated (SMP_RACE definition was no longer taken into
|
|
account when compiling sadc).
|
|
* sysstat spec file updated.
|
|
* sar and sadf manual pages updated.
|
|
* FAQ updated.
|
|
* CREDITS file updated.
|
|
|
|
2006/07/09: Version 7.0.0 - Sebastien Godard (sysstat <at> wanadoo.fr)
|
|
* S_TIME_DEF_TIME environment variable added for sar, sadc and
|
|
sadf.
|
|
* Use now sysconf() function to get the number of clock ticks
|
|
per second (HZ value) instead of using kernel include file
|
|
<sys/param.h>.
|
|
* Columns "Device", "rrqm/s" and "wrqm/s" enlarged for iostat -x.
|
|
* sysstat installation process updated to use chkconfig if

|
|
WARNING: Daily data files format has changed, and is *not*
|
|
compatible with the previous one! [0x2169]
|
|
* Option -P can now be used with sar even on SMP machines where
|
|
only one processor is available.
|
|
* Small bug fixed for mpstat, where explicitly specifying
|
|
processor 0 ("-P 0") could lead to incorrect output on UP
|
|
machines.
|
|
* Option -D added to sadf: this option displays the contents of
|
|
a data file in a database-friendly format with a timestamp
|
|
expressed in seconds from the epoch.
|
|
* sadf manual page updated.
|
|
* NLS updated.

|
|
* 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.
|
|

* 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.

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,
|
|
/proc/partitions and then /proc/stat.
|
|
* statistics are now read by iostat and mpstat as unsigned long
|
|
instead of int to avoid integer overflow.
|
|
* iostat should now handle properly the case when the 'weighted
|
|
number of milliseconds spent doing I/Os' (read in sysfs or
|
|
/proc/{partitions,diskstats}) decreases with time.
|
|
* iostat manual page updated.
|
|
* Minor temporary file vulnerability fixed in isag command.
|
|
* README, FAQ and CREDITS files updated.
|
|
* Author's email changed.
|
|
|
|
2004/02/02: Version 5.0.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* -L option added to sadc. Enable sadc to lock its output file
|
|
to prevent multiple instances from writing to it at once.
|
|
* sa1 and sysstat scripts updated to take advantage of -L option.
|
|
* Handle the case where, under very special circumstances, STDOUT
|
|
may become unavailable, and sar, iostat and mpstat are no longer
|
|
able to display anything.
|
|
* sadc as called in sysstat script also uses -F option to force
|
|
the creation of daily data file.
|
|
* sar, sadc and mpstat manual pages updated.
|
|
* Code cleaned.
|
|
* FAQ and CREDITS files updated.
|
|
|
|
2003/11/09: Version 5.0.0 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* New fields added to mpstat: %irq (%time spent servicing
|
|
interrupts) and %soft (%time spent servicing softirqs).
|
|
* sar and iostat updated to take into account time spent servicing
|
|
interrupts and softirqs when displaying percentage of time
|
|
in system mode.
|
|
* By default iostat now displays only statistics information for
|
|
devices that are used by the system. You should now use the ALL
|
|
keyword to tell iostat to display statistics for every device
|
|
including those that have never been used.
|
|
* The file version.h is now dynamically created. sysstat's version
|
|
number is now only recorded in the Makefile.
|
|
* sar manual page updated: beginning with kernels 2.4 and later,
|
|
pgpgin and pgpgout statistics are in kilobytes and not in
|
|
blocks (see linux-2.4/fs/proc/proc_misc.c and
|
|
linux-2.6/mm/page_alloc.c).
|
|
* iostat and mpstat manual pages updated.

2003/09/28: Version 4.1.7 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
WARNING: Daily data files format has changed, and is *not*
|
|
compatible with the previous one! [0x2163]
|
|
* /proc/diskstats is now the preferred source for iostat to get its
|
|
statistics. If non-existent, iostat falls back on sysfs then
|
|
on /proc/stat.
|
|
* In addition to devices, partitions can also be entered on the
|
|
command line for iostat providing that option -x is not used.
|
|
* /dev prefix has been removed from device name displayed by iostat -x.
|
|
* sar -d now looks for disks statistics in /proc/diskstats with
|
|
post 2.5 kernels.
|
|
* sar uses /proc/vmstat file with post 2.5 kernels to find paging
|
|
and swapping statistics.
|
|
* activepg, inadtypg, inaclnpg and inatarpg stats removed from
|
|
sar -B report (they were not really useful).
|
|
* sar -B now displays the number of page faults made by the system
|
|
(pgfault/s and pgmajflt/s).
|
|
* Stat on shared memory removed from sar -r and sar -R (this stat
|
|
was no longer maintained by the kernel since 2.4 because of
|
|
performance problems).
|
|
* Cached swap statistic information added to sar -r.
|
|
* sar -d now displays separate statistics for sectors that are
|
|
read from or written to devices.
|
|
* %file-sz (percentage of used file handles) is no longer displayed
|
|
by sar -v, since the upper limit for the number of open files
|
|
will self-scale with 2.6 kernels.
|
|
* sar now looks more aggressively for network devices in /proc/net/dev.
|
|
* Heading spaces in network interface names removed (sar -n).
|
|
* Fixed a problem reading /proc/interrupts when there are a lot
|
|
of CPUs (mpstat, sadc).
|
|
* NR_IRQS value increased to 256, since IA64 supports 256 irqs
|
|
per CPU.
|
|
* Some stats counters are now read as unsigned long instead of
|
|
unsigned int (pgpgin, pgpgout, pswpin, pswpout, irq_sum).
|
|
* sar and iostat manual pages updated.
|
|
* FAQ, README and CREDITS files updated.
|
|
* NLS updated.

2003/08/20: Version 4.1.6 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
WARNING: Daily data files format has changed, and is *not*
|
|
compatible with the previous one! [0x2162]
|
|
* Machine uptime calculation is now optimized on SMP machines
|
|
to minimize the consequences if an overflow condition happens.
|
|
Especially useful when asking for stats since system boot.
|
|
* -F option added to sadc. Useful to force the creation of the
|
|
daily data file: an already existing file with a wrong format
|
|
will be truncated by sadc if this option is used.
|
|
* sa1 script now calls sadc with -F option.
|
|
* The processor number to which the process is attached was no
|
|
longer displayed by sar -x. Make it appear again.
|
|
* CPU usage for processes, as displayed by sar -x and sar -X, should
|
|
now be correct on machines where HZ <> 100 (e.g. IA64 architecture).
|
|
* iostat still assumed that jiffies were 100ths of a second in some
|
|
places. Now use Linux HZ definition *everywhere*.
|
|
* The average I/O requests queue length as displayed by iostat -x was
|
|
wrongly calculated. This is now fixed.
|
|
* Manual pages updated.
|
|
* NLS updated.
|
|
* Cosmetic changes in various parts of the code.
|
|
* FAQ, README and CREDITS files updated.

2003/07/21: Version 4.1.5 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
WARNING: Daily data files format has changed, and is *not*
|
|
compatible with the previous one! Delete existing data files
|
|
in /var/log/sa directory! [0x2161]
|
|
* 'sar -x <pid>' and 'sar -X <pid>' work again.
|
|
* sar had a longstanding bug that prevented option -P from
|
|
working properly if the machine had more than 32 processors.
|
|
This is now fixed.
|
|
* Fixed a bug introduced in 4.1.2, which made some LINUX RESTART
|
|
messages to not be displayed by sar.
|
|
* sar now uses bitmap of char instead of int to avoid endianness
|
|
problems.
|
|
* sar can now handle a huge number of processors, serial lines and
|
|
network interfaces.
|
|
* FAQ updated.

WARNING: Daily data files format has changed, and is *not*
|
|
compatible with the previous one! Delete existing data files
|
|
in /var/log/sa directory! [0x2160]
|
|
* Fixed the way overflow conditions were handled by sar for
|
|
interfaces counters.
|
|
* On really big machines with 100 GB of memory or more, the values
|
|
read by sadc in /proc/meminfo would get truncated and cause havoc
|
|
in the calculations. This is now fixed.
|
|
* iostat and sar can now read many more disk entries in /proc/stat if
|
|
necessary.
|
|
* Option "-x SUM" removed for sar. It was used to tell sar to display
|
|
the total number of minor and major faults made by the system.
|
|
Unfortunately, the calculation was tricky, and the results were
|
|
uncertain...
|
|
* NLS updated. Polish translation added. Also proper charset and
|
|
encoding declarations added to fix msgfmt warnings and allow
|
|
gettext to recode between various charsets (e.g. German
|
|
translation will be shown properly both with
|
|
LANG=de_DE.ISO-8859-1, and LANG=de_DE.UTF-8)
|
|
* Code 'sanitization'.
|
|
* Manual pages updated.
|
|
* README and FAQ files updated.
|
|
|
|
2003/05/08: Version 4.1.3 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* iostat should now be fully 2.5/2.6 kernel compliant.
|
|
* Disks arrays in iostat are now dynamically sized.
|
|
* iostat: sysfs is now used in preference to /proc/stat if available.
|
|
* iostat will no longer look for statistics in /proc/partitions.
|
|
sysfs filesystem must now be available for iostat to get its
|
|
extended stats (post 2.5 kernels).
|
|
* iostat: Devices for which statistics are requested can now be entered
|
|
on the command line even if option -x is not used.
|
|
* Usage messages updated.
|
|
* Manual pages updated.
|
|
* Code cleaned (dk_drive_sum removed in iostat, long lines folded,
|
|
functions split in smaller parts, etc.)
|
|
* NLS updated. Romanian translation added.
|
|
* isag upgraded to version 1.22.

|
|
* sar -q now also displays load average for the past 15 minutes.
|
|
* -P option added to sar. This option enables sar to display
|
|
stats on a per processor basis. Options -U and '-I PROC' are
|
|
deprecated. 'sar -U ALL' is replaced by 'sar -u -P ALL', and
|
|
'sar -I PROC' by 'sar -I SUM -P ALL'.
|
|
* Fixed iowait value displayed by sar on SMP machines with pre 2.5
|
|
kernels.
|
|
* When displaying CPU utilization on SMP machines, sar now
|
|
recalculates the interval based on current CPU's tick count.
|
|
* Always check that the number of CPUs has not increased when
|
|
reading /proc/stat (sadc, mpstat).
|
|
* sadc: Don't assume that the first line in /proc/net/sockstat
|
|
concerns sockets. Check it!
|
|
* Serial lines are ignored by sadc for every kind of kernels
|
|
(UP, SMP...) if SMP_RACE is defined.
|
|
SMP_RACE is no longer defined by default in RPM packages.
|
|
* Code cleaned: Dead code removed in iostat.c, some lines longer

* mpstat now uses a bitmap of char instead of int to avoid endianness
|
|
problems. As a consequence, mpstat should now work on PowerMac
|
|
architectures.
|
|
* CPU activity as displayed by mpstat -P for a given processor was

* iostat no longer freezes if -c and -d options are used together.
|
|
* Fixed a bug that prevented iostat from displaying more than an

average of three devices with 2.4 kernels (a buffer was too small).
|
|
* Check added to ensure that sar and sadc commands are consistent.

(option -x).
|
|
* The default value for the count parameter of the sar command is
|
|
now 1 (this is how sar works with other Un*xes...). A value of

|
0 will indicate that reports are to be generated continuously.
|
|
* Code cleaned: Now always use 'double' numbers instead of the

|
reading /proc/stat file with 2.4 kernels (sar -b). This is now
|
|
fixed.
|
|
* iostat command is no longer able to save its data to a file.
|
|
In fact, iostat has never been supposed to work that way, and I
|
|
have never really maintained this option.
|
|
* iostat now also works with 2.4 kernels. It can handle the format

the standard Linux kernel have been removed (tty, iowait...).
|
|
* sar can now handle I/O and transfer rate statistics with both
|
|
2.2.x and 2.4.x Linux kernels (-b option).
|
|
* Removed %inode-sz that was displayed by sar -v, since the file
|
|
inode-max in /proc/sys/fs no longer exists in Linux 2.4.
|
|
The new 2.4.x kernels now seem to be able to allocate inode
|
|
structures dynamically, and to free them when necessary (see

|
linux/fs/inode.c).
|
|
* Removed statistics on highest in-used sockets. Relevant
|
|
counters have disappeared from sockstat file in /proc/net
|
|
for 2.4 kernels (sar -n SOCK).
|

|
* System activity files are now readable by everybody.
|
|
* Average statistics since boot time are now printed when interval
|
|
parameter is set to 0. If interval and count parameters are not
|
|
set on the command line, sar selects requested activities from
|
|
the current system activity daily data file.
|
|
* sadc, sa1 and sa2 manual pages moved to chapter 8 instead of 1m.
|
|
* iostat disk accounting patch modified to work with md drivers.
|
|
|
|

|
|
* sadc - system activity data collector added.
|
|
* sa1, sa2 and sysstat.sh shell scripts added.
|
|
* Manual pages added for sadc, sa1, sa2.

* Meaning of -i option has changed for sar.
|
|
* -d option removed for sar since it is no longer needed (we have
|
|
sadc now).
|
|
* sar now uses keywords such as ALL, SUM, etc. instead of numerical
|
|
parameters.
|
|
* iostat disk accounting patch improved.
|
|
* 'page' field in /proc/stat is no longer used by iostat (was
|
|
unreliable).
|
|
* Workaround for buggy RTC (or kernels?) added. Used when the number
|
|
of jiffies spent by the system in the idle task is decreasing in
|
|
/proc/stat.
|
|
* Manual pages updated.
|
|
* NLS updated: Portuguese translation added.
|
|
* Makefile updated.
|
|
|
|
1999/11/28: Version 2.2 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* Option -d added to sar to enable it to be started as a daemon.
|
|
* sar initialization script updated to use -d option.
|
|

|
|
* Fixed a bug that made CPU utilization displayed by iostat wrong on
|
|
SMP machines.
|
|
* Manual pages updated and moved to chapter 1 instead of 8.
|
|
* sar '-m' option renamed to '-r'.
|
|
* Display improved for iostat.
|
|
* NLS updated: Spanish translation added.
|
|

|
|
|
|
1999/10/24: Version 2.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* The sar and iostat commands can now work on non SMP-machines even
|
|
if the kernel is compiled with SMP support enabled.
|
|
* Fixed a bug that made the time displayed by iostat wrong when
|
|
reading stats back from a file.
|
|
* Added memory statistics: free/shared/buffer/cached pages (sar -m).
|
|
* Option -h added to sar to print its header periodically.
|
|
* Set unavailable fields to zero when writing iostat file.
|
|
* sar now displays 'proc/s' instead of 'fork/s' since exec'ed
|
|
processes are also taken into account.
|
|
* Manual pages updated.
|
|
* sysstat is now available in RPM format.
|
|
* Code cleaned up and made safer.
|
|
|
|
1999/09/19: Version 2.0 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* iostat now displays logical block I/O stats for each IDE device, or
|
|
global Kb/s rate for all the block devices. Stats in Kb/s for each
|
|
block device are not available for standard kernels due to Linux
|
|
poor disk accounting... Anyway a patch is provided in this version
|
|
of 'sysstat' in the 'patch' directory to fix that.
|
|
* System uptime is no longer read in /proc/uptime but computed from
|
|
the cpu line in /proc/stat.
|
|
* When stats are read from a file (option -f of iostat and sar),
|
|
values are now computed in accordance with the interval given by
|
|
the user on the command line.
|
|
* Old '-o' option for iostat removed. Now iostat can save data
|
|
into a file in a binary format and re-read them later (options
|
|
'-o' and '-f') in the same way sar does.
|
|
* Number of available processors now taken into account when
|
|
retrieving CPU usage from /proc/stat.
|
|
* Removed a bug that prevented 'sar -U' to work on SMP machines.
|
|
* Fixed a bug that made per-CPU average usage wrong on SMP machines.
|
|
* Use of option -U is now possible for sar when reading from a file
|
|
even if the machine is not an SMP one.
|
|
* Fixed a bug that prevented sar from re-reading stats saved in a file
|
|
when -I or -U option had been used.
|
|
* iostat modified to work on SMP machines.
|
|
* Changed the formula used to display stats in order not to get
|
|
numbers greater than UINT_MAX.
|
|
* System name, release number and hostname are now saved in
|
|
system activity files.
|
|
* iostat now displays system name, release number and hostname
|
|
when invoked.
|
|
* Daily system activity file rotation added for sar.
|
|
* Improved 64-bit system support.
|
|
* CREDITS file added.
|
|
* NLS updated: German translation added.
|
|
* Manual pages updated.
|
|
* Makefile updated: Do not call msgfmt if NLS is not enabled.
|
|
|
|
1999/06/25: Version 1.2 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* Better NLS support (date, time and numerical values, NLS enabled
|
|
for sar, etc.).
|
|
* System activity daily file structure changed: Is now independent of
|
|
the locale and is more compact.
|
|
* sar updated to support SMP machines (per CPU accounting).
|
|
* Code cleaned, man pages updated...
|
|
|
|
1999/05/28: Version 1.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
|
|
* NLS support added. French translation started but needs to be
|
|
completed.
|
|
* sar updated to support more than 16 interrupts (potential APIC
|
|
interrupt sources).
|
|
* A few typos removed (man pages, etc.).
|
|
* Author email address updated :-)
|
|
* Tested on kernel 2.2.5.
|
|
|
