1146 when data are saved into a file with option -o.
1147 * [Yan Gao]: Update iostat manual page: Don't say that device
1148 saturation occurs when %util is close to 100% for devices
1149 serving multiple requests simultaneously.
1150 * Documentation fixes and updates.
1151 * Several manual pages updated (sar, sadc, sadf, sa1, sa2, sysstat).
1154 2013/06/09: Version 10.1.6 - Sebastien Godard (sysstat <at> orange.fr)

1158 * Code cleaned: Removed several unused constants from header files.
1159 * Sysstat command options can now be 'collapsed' (grouped) when
1160 not followed by an argument. So it's now possible for example
1161 to enter 'iostat -px 2 5' since no device name is given to
1162 option -p. This also concerns pidstat option -U.
1163 * Fixed type for "memfree" and "intr" elements in XSD document.
1164 * Removed functions used to count number of items from rd_stats.c
1165 and put them in a separate file (count.c).

1172 * mpstat now takes into account every interrupt per processor
1173 so that their number adds up to the number displayed for CPU "all".
1174 * [Peter Schiffer]: systemd unit file couldn't be installed
1175 because PKG_PROG_PKG_CONFIG macro wasn't expanded in configure
1176 script. This is now fixed.
1177 * [Benno Schulenberg]: Fixed a small inconsistency in pidstat
1179 * Cosmetic fixes in pidstat manual page.
1180 * NLS updated (de, eo, fi, fr, ja, nb, nl, ru, uk, vi).

1188 * sar now stops and displays its average stats when it receives
1190 * pidstat now displays task's UID for all tasks.
1191 * pidstat: -U option added. This option tells pidstat to display
1192 the username of the task instead of its UID. When this option is
1193 followed by a user name, then only tasks belonging to the
1194 specified user are displayed by pidstat.
1195 * pidstat manual page updated.
1196 * Now use sigaction() instead of signal() for signals handling
1197 to avoid portability problems.

1212 WARNING: This breaks compatibility with older sar data
1213 files format for IPv6 statistics.
1214 * [Peter Schiffer]: Added option -y to iostat. This option
1215 prevents iostat from displaying its first report with
1216 statistics since system boot.
1217 * [Peter Schiffer]: Increase NR_CPUS and NR_IRQS values.
1218 * [John Lau]: sadc didn't collect all its activities when

1262 * sadf: New option -t added. This option tells sadf to display
1263 the timestamps in the local time of the data file creator
1264 instead of UTC. The same option exists for sar.
1265 * [Peter Schiffer]: Various cosmetic changes in manual pages
1266 and usage messages displayed by sysstat commands.
1269 * sar, sadf and iostat manual pages updated.
1271 2012/05/16: Version 10.0.5 - Sebastien Godard (sysstat <at> orange.fr)

1487 * Added support for tickless CPUs in sar and mpstat.
1488 * NLS was not taken into account when mpstat or sar were displaying
1489 some null statistics. This is now fixed.
1490 * sadc no longer syncs data with its output file contents. It

1609 * IPv6 support added. A bunch of new metrics have been added to
1610 sar, enabling the user to display statistics for IPv6 protocol
1611 family (IPv6, ICMPv6, UDPv6 and network sockets).
1612 * sadc updated: Option "-S IPV6" tells sadc to collect IPv6
1614 * sadf command updated to take into account IPv6 statistics.
1615 * Options -S (for sadc), -P (for mpstat, sar and sadf), -p (for
1616 iostat and pidstat) and -n and -I (for sar) now accept a list of
1617 comma-separated arguments.
1618 * [Ivana Varekova]: Make iostat display statistics for devices only
1619 (and not partitions) when not using its option -d. This was
1620 no longer possible with kernels 2.6.25 and later because iostat
1621 couldn't distinguish between devices and partitions any more.
1622 * iostat's options -x and -p are no longer mutually exclusive:
1623 Extended statistics are now available even for partitions with
1625 * iostat was unable to read stats from sysfs for devices who had
1626 a slash in their names (for example, iostat -p /dev/cciss/c0d0
1627 didn't work properly before). This is now fixed.
1628 * [Amir Rapson]: Fixed a bug in iostat where %CPU spent

1660 2008/09/30: Version 8.1.6 - Sebastien Godard (sysstat <at> orange.fr)
1661 * [David Alan Gilbert]: Option -h added to pidstat. This
1662 option is used to display all activities horizontally on a
1664 * Fixed a bug in pidstat: When pidstat was used to monitor a
1665 process and all its threads (with pidstat's option -t), it
1666 could display weird values if the thread group leader terminated.
1667 * Header line displayed by sar, iostat, mpstat, pidstat and
1668 sadf -H now includes the number of CPU.
1669 * Use the correct word TGID instead of PID with pidstat -t.
1670 * mpstat now displays stats for all interrupts, including NMI,
1672 * sar and sadf now check that CPU activity is available in file.
1673 * iostat's option -t now always displays the date and the time.
1674 * Added option "--disable-documentation" to ./configure. Using
1675 this option prevents documentation files (including manual
1676 pages) from being installed.
1677 * iconfig script updated. Now ask the user for documentation
1678 and isag script installation.
1679 * Manual pages updated.
1680 * NLS updated. Indonesian and Chinese (traditional) translations

1692 * pidstat has also been updated to be able to display time
1693 spent in virtual machine for a task, and for a task and all
1695 * Option -S added to sar: This options tells sar to display
1696 swap space utilization. Option -r now only displays memory
1698 * Added %swpcad to sar -S (percentage of cached swap memory
1699 in relation to the amount of used swap space).
1700 * Added kbcommit and %commit to sar -r (amount and percentage
1701 of memory needed for current workload).
1702 * sadf -x now distinguishes between options -r and -R.
1703 * sadf command updated to take into account new fields
1704 (%guest, %swpcad, etc.)
1705 * [Ivana Varekova]: iostat now displays the total number of
1706 operations per second in the NFS report.
1707 * Fixed iostat so that %system (percentage of CPU utilization
1708 that occurred while executing at system level) also takes
1709 into account time spent to service interrupts and softirqs.
1710 * Added a missing header line for activities with multiple
1711 outputs displayed by sar (eg. sar -rR ...).
1712 * Makefile updated: There is now a dedicated target to install
1713 or uninstall manual pages.
1714 * Manual pages updated.
1716 * XSD and DTD documents updated.

1721 option "-u ALL". sadf has also been updated to be able to
1723 * mpstat can now display per-CPU interrupts statistics with its
1724 option "-I CPU". This was a feature available in sar that was
1725 removed in previous sysstat version.
1726 * mpstat uses now a separate option ("-I SUM") to display the
1727 total number of interrupts for each processor.
1728 * Option -A added to mpstat. This switch tells mpstat to display
1729 all possible activities.
1730 * NFS v4 support added to sar -n NFS(D). When both NFS v3 and
1731 NFS v4 are used, stats from NFS v3 and NFS v4 are added
1732 together [DEBIAN bug#434442].
1733 * Code cleaned: mpstat, iostat and pidstat now use the common
1734 functions from rd_stats.c to read CPU stats from /proc/stat;
1735 Computing extended disk statistics (service time, etc.) is now
1736 done in one place (common function used by iostat, sar, sadf).
1737 * All sysstat commands are made consistent with how parameters
1738 are interpreted: "COMMAND <interval>" now generates a report
1739 continuously, "COMMAND <interval> 0" causes an error,
1740 "COMMAND 0" displays a report since system startup
1741 [DEBIAN bug#475707].
1742 * Changed XML output for processes and context switches displayed
1743 by sadf -x to be consistent with output from sar.
1744 * mpstat and sar manual pages updated.
1745 * isag script updated.
1747 * DTD and XML Schema updated.
1750 2008/05/25: Version 8.1.3 - Sebastien Godard (sysstat <at> orange.fr)
1751 WARNING: Daily data files format has changed, and is *not*
1752 compatible with the previous one! [0x2170]
1753 * sar, sadc and sadf heavily modified. It is now easier to add
1754 (or remove) activities since sar and sadc have been rewritten
1755 in a non-monolithic way with a generic design architecture.
1756 * Option -c removed from sar. Task creation and context switch
1757 activities are now merged and available with option -w.
1758 * sar no longer displays interrupts per processor statistics.
1759 This feature will be included in mpstat in next sysstat version.
1760 * Option -S added to sadc. This option replaces previous options
1761 -I or -d, and is used to select activities that should be
1762 collected and saved in file. It is even possible to
1763 select each activity collected by sadc.
1764 * Format of data files created by sar/sadc heavily modified.
1765 In some cases, it is now possible to add or remove activities
1766 while keeping a compatible format that can be read by a previous
1767 or future sysstat version.
1768 * sadf now only displays activities that have been explicitly
1770 * sar now checks that devices displayed by option -d are whole
1771 devices (and not partitions) using sysstat.ioconf configuration
1772 file. If this file is not found in its default directory, then
1773 sysstat looks for it in current directory.
1774 * gettextize entire usage() messages so that translators have
1776 * DTD and XML Schema updated.
1777 * Manual pages updated.
1778 * Crontab samples updated.

1783 * [Ivana Varekova]: iostat now displays read and write operations
1784 per second in the NFS report.
1785 * [Tomas Mraz]: sadc now retries to write its buffers when the
1786 write() call has been interrupted by a signal.
1787 * Use setbuf() call instead of fflush() to indicate that data
1788 should not be buffered to stdout.
1789 * Option -h added to sadf. Used with options -d or -D, it
1790 indicates that all activities should be displayed horizontally
1791 on a single line of data.
1792 * sadf -d and sadf -D now display the list of fields for easier
1794 * sadf and iostat manual pages updated.
1795 * NLS updated: Chinese (simplified) translation added, other
1796 translations updated.

1804 a system activity data file.
1805 * Machine architecture is now displayed in the reports header.
1806 sadf -x also displays machine architecture.
1807 * DTD and XML Schema documents updated.
1808 * The number of processors was not properly calculated on
1809 machines where a directory named cpuidle was present in the
1810 /sys/devices/system/cpu directory [GENTOO bug# 207886].
1811 * Use __CPU_SETSIZE definition from <sched.h> instead of a
1812 static definition for the maximum number of CPUs (NR_CPUS).
1813 * Improved error messages displayed by sysstat's commands.
1814 * NLS updated: Finnish translation added, Dutch translation
1817 * Code cleaned and documented. Linux-like style applied to
1818 code source. Large functions split into smaller ones.
1820 2008/01/06: Version 8.0.4 - Sebastien Godard (sysstat <at> orange.fr)
1821 * Removed a 'packed' attribute in pidstat.h that generated

2107 only one processor is available.
2108 * Small bug fixed for mpstat, where explicitly specifying
2109 processor 0 ("-P 0") could lead to incorrect output on UP
2111 * Option -D added to sadf: this option displays the contents of
2112 a data file in a database-friendly format with a timestamp
2113 expressed in seconds from the epoch.
2114 * sadf manual page updated.
2116 * CREDITS file updated.

2159 * sar now displays its statistics to STDOUT in addition to saving
2160 them into the file when option -o has been entered on the
2162 * sar now recalculates number of system items (network interfaces,
2163 disks, serial lines, etc.) when a file rotation happens.
2164 * Make sar -b work again when used without option -d.
2165 * Small changes so that sysstat can be compiled with gcc-4.0.1.
2166 * sysstat updated so that it may be installed on Slackware.
2167 * sar manual page updated.

2172 WARNING: Daily data files format has changed, and is *not*
2173 compatible with the previous one! [0x2167]
2174 * Additional fields added to sar -y (TTY statistics). sar, sadf
2176 * sar -d now only reports for used devices (devices with non zero
2178 * Stricter sadf syntax checking: various output formats are now
2180 * Stricter iostat syntax checking: -k and -m options are now
2182 * iostat: option -m is now taken into account even when
2183 displaying extended statistics.
2184 * Fixed a bug that prevented iostat from displaying stats about
2185 devices that were unknown in sysstat.ioconf file.
2186 * iostat might display bogus sectors values when the corresponding
2187 kernel counters had overflown. This is now fixed.
2188 * "sadf datafile -- -A" should also display individual interrupts
2189 if available in datafile.
2190 * Fixed a bug that prevented sar -x from displaying stats about a
2191 process if it was after the first 256 processes in the process
2193 * Manual pages updated.
2194 * sa1 script always uses option -d in crontab.
2195 * sysstat.ioconf device configuration file updated.
2197 * FAQ and CREDITS files updated.
2200 2005/02/25: Version 5.1.5 - Sebastien Godard (sysstat <at> wanadoo.fr)
2201 * -x option added to sadf: it is now able to display the contents of
2202 a sar datafile in XML. The corresponding DTD (Document Type
2203 Definition) is included in the sysstat package.
2204 * Small code change so that sysstat may be compiled with gcc-4.0.
2205 * A few typos fixed in formulas used by sadf to display stats
2206 on machines where HZ<>100 (typos appeared in sysstat 5.1.4).
2207 * Fixed a bug in the stats displayed by sar -d.
2208 * Removed a false workaround in iostat: better show that the kernel
2209 is buggy rather than display a value that seems correct but which
2211 * Fixed sar -i option which might not select records at the specified
2212 interval on machines with multiple processors.
2213 * NLS updated and cleaned. Do no longer translate fields names (sar,
2214 iostat, etc.). Changed nb_NO.po and nn_NO.po files to nb.po and
2216 * Bug fixed in spec file: when installing sysstat i586 RPM package,

2226 WARNING: Daily data files format has changed, and is *not*
2227 compatible with the previous one! [0x2166]
2228 * NFS client and server statistics added to sar.
2229 * sar -d now only reads stats for devices (and not partitions)
2230 from /proc/partitions. (This is what it was already doing with
2232 * Display routines from sadf merged, so that -ppc and -db
2233 always output the same values.
2234 * sadf updated to handle NFS statistics.
2235 * sadf can now display the header of a data file (option -H).
2236 * Define MAX_BLKDEV in ioconf.h if non-existent in <linux/major.h>.
2237 * sar now looks for sadc in one directory only, specified at
2238 compile time. Moreover it is now possible to have two different
2239 sysstat versions installed: sar knows where its sadc counterpart
2241 * sapath.in removed. SADC_PATH is defined in CONFIG file.
2242 * sar and sadf manual pages updated.
2243 * sysstat.ioconf file updated.
2244 * Fixed a bug in i386 RPM package, where sadc location was not

2252 WARNING: Daily data files format has changed, and is *not*
2253 compatible with the previous one! [0x2165]
2254 * Option -p added to sar: It enables sar (and also sadf) to
2255 display device names as they appear in /dev.
2256 * sysstat.ioconf support added.
2257 * New fields added to sar -d (more disk activities displayed):
2258 avgrq-sz, avgqu-sz, await, svctm, %util.
2259 * sadf updated to handle new disk activities.
2260 * I/O and transfer rate statistics as displayed by sar -b are
2261 available whatever the version of the kernel is (i.e. even on
2263 * Disk stats are read by sadc from /proc/stat only if they cannot
2264 be read from /proc/{partitions,diskstats}.
2265 * sadc: Some variables declarations moved around.
2266 * sar manual page updated.
2267 * Added workaround for EMC PowerPath driver bug to enable iostat
2268 to display proper device name.
2269 * Makefile updated: Use $@ and $< everywhere; 'make {iostat,mpstat}'
2270 work again; Create object files before linking; Removed unused
2271 IOS_DFLAGS variable; Use DESTDIR variable everywhere; Create
2272 libsysioc.a; Install sysstat.ioconf.
2274 * README and CREDITS files updated.
2276 2004/11/05: Version 5.1.2 - Sebastien Godard (sysstat <at> wanadoo.fr)
2277 * sar -d now also uses /proc/partitions to get its data.
2278 From now on sar -d looks in the following files in that order:
2279 /proc/diskstats, /proc/partitions, /proc/stat.
2280 * sadc writes disks data to file only if -d option is explicitly
2281 set on the command line.
2282 * sadc now reads individual interrupts data from /proc/stat only
2283 if -I option was entered on the command line.
2284 * 'sar -A' is now equivalent to 'sar -bBcdqrRuvwWy -I SUM -I XALL
2285 -n FULL -P ALL' (i.e. individual interrupts are also included
2287 * Option -m now tells iostat to display statistics in megabytes
2288 per second instead of blocks per second.
2289 * Make history (number of days to keep log files) configurable
2290 in /etc/sysconfig/sysstat file, which is used by sa2 script.
2291 * Now use Vixie cron to launch sadc when possible.
2292 * sadc, sa1 and sa2 may now be installed in another directory
2293 than ${PREFIX}/lib/sa. This is useful on 64-bit systems where
2294 the proper directory should be ${PREFIX}/lib64/sa.
2295 * When uninstalling sysstat, always delete sysstat script,
2296 config file and links in /etc tree. Also always delete
2298 * sysstat script now returns real exit code.
2299 * sar/sadc: Stricter syntax checking for -x and -X options use.
2300 * sysstat "*.sh" files renamed in "*.in".
2302 * sadc and sar manual pages updated.
2305 * CREDITS and README files updated.
2307 2004/10/09: Version 5.1.1 - Sebastien Godard (sysstat <at> wanadoo.fr)
2308 WARNING: Daily data files format has changed, and is *not*
2309 compatible with the previous one! [0x2164]
2310 * sar now reads CPU data, number of context switches, number
2311 of sectors and total number of interrupts as 64-bit unsigned
2312 values. It also reads the number of running processes as
2313 unsigned long instead of unsigned int.
2314 * sadf - System activity data formatter command added.
2315 * Options -h and -H removed from sar. "sar -h" is replaced by
2316 "sadf -p", and "sar -H" is replaced by "sadf -d". Read sadf
2317 manual page, as its syntax is a bit different from that of sar.
2318 * Common code for sar and sadf moved to sa_common.c file.
2319 * pid_stats members don't need to be aligned since these stats
2320 are not written to daily data files. Packing them saves some
2321 memory on 32-bit architectures.
2322 * No longer indicate that -x and -X are possible options for sadc.
2323 They are only useful when used as options for sar, not sadc.
2324 * Minor buffer overrun fixed in iostat.
2325 * Updated CPU header for iostat and mpstat: CPU used while executing
2326 at the system level is displayed as '%system' by iostat (like sar)
2327 and as '%sys' by mpstat.
2328 * sadf manual page added. Other manual pages updated.
2329 * Updated the GPL notices (the address of the FSF was wrong).
2332 * README, FAQ and CREDITS files updated.
2334 2004/08/09: Version 5.0.6 - Sebastien Godard (sysstat <at> wanadoo.fr)
2335 * The value for file-sz reported by sar -v was a number of free
2336 handles, and not a number of used ones! This is now fixed (and
2337 this is really now a number of _used_ file handles).
2338 * Now ask during config stage for the directory where sadc will
2339 be located. This may be useful for some systems where sadc
2340 needs to be installed in a specific location (e.g. on 64 bit
2341 s390 systems, the proper directory should be /usr/lib64/sa).
2342 * sa1 script updated: Use '-' to specify current daily data file
2343 instead of guessing its name using current date.
2344 * NLS updated: be consistent with GNU gettext standards.
2345 * iostat manual page updated.
2348 * CREDITS file updated.
2350 2004/06/08: Version 5.0.5 - Sebastien Godard (sysstat <at> wanadoo.fr)
2351 * Timestamp is no longer limited to 11 characters. This should
2352 avoid problems with somes locales (for example Japanese locale,
2353 where 'mojibake' used to be displayed by sar and mpstat sometimes).
2354 * Fixed a bug in sysstat RPM spec file (symlinks to sysstat
2355 script were wrong in /etc/rc.d directories).
2356 * sar now checks parameters for options -n, -s and -e more
2358 * NLS updated: Japanese translation added.
2359 * Various typos fixed in several files (manual pages, README, etc.)
2360 * CREDITS file updated.
2362 2004/05/20: Version 5.0.4 - Sebastien Godard (sysstat <at> wanadoo.fr)
2363 * When trying to lock file, sadc now checks for both EWOULDBLOCK
2364 and EAGAIN error codes to be portable.
2365 * sar could sometimes display a line whose time stamp was greater
2366 than the limit set by -e option. This is no longer possible.
2367 * The sadc command in sysstat.sh script had to be enclosed in
2368 quotes to work when called via 'su -c'.
2369 * The sysstat.sh script was sending the output of sadc command
2370 to stdout instead of the standard system activity file. This
2372 * Outfile must now be explicitly set to "-" for sadc to use the
2373 standard system activity file.
2375 * iostat manual page updated. Typo fixed in sadc manual page.
2376 * Fixed the "Save picture" option of isag script.
2378 2004/04/07: Version 5.0.3 - Sebastien Godard (sysstat <at> wanadoo.fr)
2379 * iostat now reads the number of sectors in /proc/diskstats or
2380 from sysfs as 64-bit unsigned values.
2381 * iostat and mpstat now read CPU data and the number of
2382 interrupts in /proc/stat as 64-bit unsigned values.
2383 * sar uses "%u" instead of "%d" to read unsigned integer
2384 values _everywhere_.
2385 * sar and sadc are now a little bit more verbose when dealing
2386 with invalid activity files.
2387 * Network interface name size is now read from include file
2390 * Slovak translation added. NLS updated.
2391 * Typo fixed in iostat manual page.
2392 * Makefile and CREDITS file updated.
2393 * isag upgraded to version 1.26 (isag package release 0.81.0).
2395 2004/03/10: Version 5.0.2 - Sebastien Godard (sysstat <at> wanadoo.fr)
2396 * iostat will _again_ look for statistics in /proc/partitions if
2397 available. Too many production servers are still using 2.2.x or
2398 2.4.x kernels and iostat must be able to display extended stats
2399 also for them (/proc/partitions support was removed in sysstat
2400 version 4.1.3). So now, iostat gets its statistics from the
2401 following sources in that order: /proc/diskstats, sysfs,
2402 /proc/partitions and then /proc/stat.
2403 * statistics are now read by iostat and mpstat as unsigned long
2404 instead of int to avoid integer overflow.
2405 * iostat should now handle properly the case when the 'weighted
2406 number of milliseconds spent doing I/Os' (read in sysfs or
2407 /proc/{partitions,diskstats}) decreases with time.
2408 * iostat manual page updated.
2409 * Minor temporary file vulnerability fixed in isag command.
2410 * README, FAQ and CREDITS files updated.
2411 * Author's email changed.
2413 2004/02/02: Version 5.0.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2414 * -L option added to sadc. Enable sadc to lock its output file
2415 to prevent multiple instances from writing to it at once.
2416 * sa1 and sysstat scripts updated to take advantage of -L option.
2417 * Handle the case where, under very special circumstances, STDOUT
2418 may become unavailable, and sar, iostat and mpstat are no longer
2419 able to display anything.
2420 * sadc as called in sysstat script also uses -F option to force
2421 the creation of daily data file.
2422 * sar, sadc and mpstat manual pages updated.
2424 * FAQ and CREDITS files updated.
2426 2003/11/09: Version 5.0.0 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2427 * New fields added to mpstat: %irq (%time spent servicing
2428 interrupts) and %soft (%time spent servicing softirqs).
2429 * sar and iostat updated to take into account time spent servicing
2430 interrupts and softirqs when displaying percentage of time
2432 * By default iostat now displays only statistics information for
2433 devices that are used by the system. You should now use the ALL
2434 keyword to tell iostat to display statistics for every device
2435 including those that have never been used.
2436 * The file version.h is now dynamically created. sysstat's version
2437 number is now only recorded in the Makefile.
2438 * sar manual page updated: beginning with kernels 2.4 and later,
2439 pgpgin and pgpgout statistics are in kilobytes and not in
2440 blocks (see linux-2.4/fs/proc/proc_misc.c and
2441 linux-2.6/mm/page_alloc.c).
2442 * iostat and mpstat manual pages updated.
2443 * Makefile updated: don't process NLS files if they are up-to-date.
2444 * sysstat's RPM spec file updated to enable clean, non-root builds.
2446 * FAQ and CREDITS files updated.
2448 2003/09/28: Version 4.1.7 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2449 WARNING: Daily data files format has changed, and is *not*
2450 compatible with the previous one! [0x2163]
2451 * /proc/diskstats is now the preferred source for iostat to get its
2452 statistics. If non-existent, iostat falls back on sysfs then
2454 * In addition to devices, partitions can also be entered on the
2455 command line for iostat providing that option -x is not used.
2456 * /dev prefix has been removed from device name displayed by iostat -x.
2457 * sar -d now looks for disks statistics in /proc/diskstats with
2459 * sar uses /proc/vmstat file with post 2.5 kernels to find paging
2460 and swapping statistics.
2461 * activepg, inadtypg, inaclnpg and inatarpg stats removed from
2462 sar -B report (they were not really useful).
2463 * sar -B now displays the number of page faults made by the system
2464 (pgfault/s and pgmajflt/s).
2465 * Stat on shared memory removed from sar -r and sar -R (this stat
2466 was no longer maintained by the kernel since 2.4 because of
2467 performance problems).
2468 * Cached swap statistic information added to sar -r.
2469 * sar -d now displays separate statistics for sectors that are
2470 read from or written to devices.
2471 * %file-sz (percentage of used file handles) is no longer displayed
2472 by sar -v, since the upper limit for the number of open files
2473 will self-scale with 2.6 kernels.
2474 * sar now looks more aggressively for network devices in /proc/net/dev.
2475 * Heading spaces in network interface names removed (sar -n).
2476 * Fixed a problem reading /proc/interrupts when there are a lot
2477 of CPUs (mpstat, sadc).
2478 * NR_IRQS value increased to 256, since IA64 supports 256 irqs
2480 * Some stats counters are now read as unsigned long instead of
2481 unsigned int (pgpgin, pgpgout, pswpin, pswpout, irq_sum).
2482 * sar and iostat manual pages updated.
2483 * FAQ, README and CREDITS files updated.
2486 2003/08/20: Version 4.1.6 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2487 WARNING: Daily data files format has changed, and is *not*
2488 compatible with the previous one! [0x2162]
2489 * Machine uptime calculation is now optimized on SMP machines
2490 to minimize the consequences if an overflow condition happens.
2491 Especially useful when asking for stats since system boot.
2492 * -F option added to sadc. Useful to force the creation of the
2493 daily data file: an already existing file with a wrong format
2494 will be truncated by sadc if this option is used.
2495 * sa1 script now calls sadc with -F option.
2496 * The processor number to which the process is attached was no
2497 longer displayed by sar -x. Make it appear again.
2498 * CPU usage for processes, as displayed by sar -x and sar -X, should
2499 now be correct on machines where HZ <> 100 (e.g. IA64 architecture).
2500 * iostat still assumed that jiffies were 100ths of a second in some
2501 places. Now use Linux HZ definition *everywhere*.
2502 * The average I/O requests queue length as displayed by iostat -x was
2503 wrongly calculated. This is now fixed.
2504 * Manual pages updated.
2506 * Cosmetic changes in various parts of the code.
2507 * FAQ, README and CREDITS files updated.
2509 2003/07/21: Version 4.1.5 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2510 WARNING: Daily data files format has changed, and is *not*
2511 compatible with the previous one! Delete existing data files
2512 in /var/log/sa directory! [0x2161]
2513 * 'sar -x <pid>' and 'sar -X <pid>' work again.
2514 * sar had a longstanding bug that prevented option -P from
2515 working properly if the machine had more than 32 processors.
2517 * Fixed a bug introduced in 4.1.2, which made some LINUX RESTART
2518 messages to not be displayed by sar.
2519 * sar now uses bitmap of char instead of int to avoid endianness
2521 * sar can now handle a huge number of processors, serial lines and
2525 2003/07/01: Version 4.1.4 - Sebastien Godard <sebastien.godard@wanadoo.fr>

2527 compatible with the previous one! Delete existing data files
2528 in /var/log/sa directory! [0x2160]
2529 * Fixed the way overflow conditions were handled by sar for
2530 interfaces counters.
2531 * On really big machines with 100 GB of memory or more, the values
2532 read by sadc in /proc/meminfo would get truncated and cause havoc
2533 in the calculations. This is now fixed.
2534 * iostat and sar can now read many more disk entries in /proc/stat if
2536 * Option "-x SUM" removed for sar. It was used to tell sar to display
2537 the total number of minor and major faults made by the system.
2538 Unfortunately, the calculation was tricky, and the results were
2540 * NLS updated. Polish translation added. Also proper charset and
2541 encoding declarations added to fix msgfmt warnings and allow
2542 gettext to recode between various charsets (e.g. German
2543 translation will be shown properly both with
2544 LANG=de_DE.ISO-8859-1, and LANG=de_DE.UTF-8)
2545 * Code 'sanitization'.
2546 * Manual pages updated.
2547 * README and FAQ files updated.
2549 2003/05/08: Version 4.1.3 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2550 * iostat should now be fully 2.5/2.6 kernel compliant.
2551 * Disks arrays in iostat are now dynamically sized.
2552 * iostat: sysfs is now used in preference to /proc/stat if available.
2553 * iostat will no longer look for statistics in /proc/partitions.
2554 sysfs filesystem must now be available for iostat to get its
2555 extended stats (post 2.5 kernels).
2556 * iostat: Devices for which statistics are requested can now be entered
2557 on the command line even if option -x is not used.
2558 * Usage messages updated.
2559 * Manual pages updated.
2560 * Code cleaned (dk_drive_sum removed in iostat, long lines folded,
2561 functions split in smaller parts, etc.)
2562 * NLS updated. Romanian translation added.
2563 * isag upgraded to version 1.22.

2566 WARNING: Daily data files format has changed, and is *not*
2567 compatible with the previous one! Delete existing data files
2568 in /var/log/sa directory! [0x215f]
2569 * sar -q now also displays load average for the past 15 minutes.
2570 * -P option added to sar. This option enables sar to display
2571 stats on a per processor basis. Options -U and '-I PROC' are
2572 deprecated. 'sar -U ALL' is replaced by 'sar -u -P ALL', and
2573 'sar -I PROC' by 'sar -I SUM -P ALL'.
2574 * Fixed iowait value displayed by sar on SMP machines with pre 2.5
2576 * When displaying CPU utilization on SMP machines, sar now
2577 recalculates the interval based on current CPU's tick count.
2578 * Always check that the number of CPUs has not increased when
2579 reading /proc/stat (sadc, mpstat).
2580 * sadc: Don't assume that the first line in /proc/net/sockstat
2581 concerns sockets. Check it!
2582 * Serial lines are ignored by sadc for every kind of kernels
2583 (UP, SMP...) if SMP_RACE is defined.
2584 SMP_RACE is no longer defined by default in RPM packages.
2585 * Code cleaned: Dead code removed in iostat.c, some lines longer
2586 than 80 chars folded, etc.
2587 * sar manual page updated.

2596 I/O wait mode (with 2.5 kernels and above).
2597 * Values like -1 and -2 are no longer aliases for keywords
2598 ALL and XALL (sar -U, sar -I, mpstat -P).
2599 * Buglet fixed in iostat.h.
2600 * LC_CTYPE needs to be set, or it will emit messages with ?????? only
2601 on some locales, especially ja_JP.eucJP
2602 * sar, mpstat and iostat manual pages updated.
2604 * CREDITS file updated.
2605 * Typo removed in FAQ file.
2607 2002/11/13: Version 4.0.7 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2608 * Make data for timestamp 00:00:00 appear in one of the daily data
2609 files when sar/sadc rotates its output file.
2610 * Take out check for non SMP configuration when asking for

2615 2002/08/04: Version 4.0.6 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2616 * mpstat now uses a bitmap of char instead of int to avoid endianness
2617 problems. As a consequence, mpstat should now work on PowerMac
2619 * CPU activity as displayed by mpstat -P for a given processor was
2620 in a wrong range on SMP machines (e.g. 0-50% for a dual processor
2622 * Missing bitmap initialization fixed in mpstat.c.
2623 * Configuration script updated.

2712 * Load averages and queue length statistics added (option -q for sar).
2713 * Per device statistics added (option -d for sar). Kernel 2.4 only.
2714 * Better accuracy when computing average for some statistics.
2715 * Display all the contents of a daily data file when the count
2716 parameter is not given on the command line.

2730 Tweedie's I/O accounting patch to display extended statistics
2732 * The default value for the count parameter of the sar command is
2733 now 1 (this is how sar works with other Un*xes...). A value of
2734 0 will indicate that reports are to be generated continuously.
2735 * Code cleaned: Now always use 'double' numbers instead of the
2736 INT_PART, INT_VAL, DEC_PART and DEC_VAL macros.
2737 * Don't assume that jiffies are 100ths of a second. Use Linux
2738 HZ definition instead.
2739 * NLS updated (small fix).
2740 * sar and iostat manual pages updated.

2782 compatible with the previous one!
2783 * sar now displays timestamps in locale time when reading data
2784 from its daily data files. -t option has been added to sar,
2785 to enable it to display timestamps in the original locale
2786 time of the data file creator.
2787 * Size of various buffers made larger.
2788 * Number of interrupts per second for 'all' CPU displayed by the
2789 mpstat command was wrong. This is now fixed.

2840 * Documentation added in ${PREFIX}/doc/sysstat-x.y.
2842 2000/02/20: Version 3.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2843 * Fixed a bug that made average numbers wrong for some statistics
2844 when reading them from a system activity file.
2845 * Fixed a bug that prevented the user from retrieving some
2846 statistics when reading them from a system activity file.

2849 * System activity files are now readable by everybody.
2850 * Average statistics since boot time are now printed when interval
2851 parameter is set to 0. If interval and count parameters are not
2852 set on the command line, sar selects requested activities from
2853 the current system activity daily data file.
2854 * sadc, sa1 and sa2 manual pages moved to chapter 8 instead of 1m.
2855 * iostat disk accounting patch modified to work with md drivers.

2862 * System activity data file now records system restarts.
2863 * Every records in the iostat and system activity data files have
2864 their own timestamp now.

2867 * Per-process statistics added.
2868 * System minor and major fault statistics added.
2869 * TTY device statistics added.

2875 * S_TIME_FORMAT environment variable added.
2876 * Meaning of -i option has changed for sar.
2877 * -d option removed for sar since it is no longer needed (we have
2879 * sar now uses keywords such as ALL, SUM, etc. instead of numerical
2881 * iostat disk accounting patch improved.
2882 * 'page' field in /proc/stat is no longer used by iostat (was
2884 * Workaround for buggy RTC (or kernels?) added. Used when the number
2885 of jiffies spent by the system in the idle task is decreasing in
2887 * Manual pages updated.
2888 * NLS updated: Portuguese translation added.
2891 1999/11/28: Version 2.2 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2892 * Option -d added to sar to enable it to be started as a daemon.
2893 * sar initialization script updated to use -d option.
2894 * Option -V added to sar and iostat (print version number and usage).
2895 * Fixed a bug that made CPU utilization displayed by iostat wrong on
2897 * Manual pages updated and moved to chapter 1 instead of 8.
2898 * sar '-m' option renamed to '-r'.
2899 * Display improved for iostat.
2900 * NLS updated: Spanish translation added.
2901 * Patch against kernel 2.2.13 added for iostat.
2903 1999/10/24: Version 2.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2904 * The sar and iostat commands can now work on non SMP-machines even
2905 if the kernel is compiled with SMP support enabled.
2906 * Fixed a bug that made the time displayed by iostat wrong when
2907 reading stats back from a file.
2908 * Added memory statistics: free/shared/buffer/cached pages (sar -m).
2909 * Option -h added to sar to print its header periodically.
2910 * Set unavailable fields to zero when writing iostat file.
2911 * sar now displays 'proc/s' instead of 'fork/s' since exec'ed
2912 processes are also taken into account.
2913 * Manual pages updated.
2914 * sysstat is now available in RPM format.
2915 * Code cleaned up and made safer.
2917 1999/09/19: Version 2.0 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2918 * iostat now displays logical block I/O stats for each IDE device, or
2919 global Kb/s rate for all the block devices. Stats in Kb/s for each
2920 block device are not available for standard kernels due to Linux
2921 poor disk accounting... Anyway a patch is provided in this version
2922 of 'sysstat' in the 'patch' directory to fix that.
2923 * System uptime is no longer read in /proc/uptime but computed from
2924 the cpu line in /proc/stat.
2925 * When stats are read from a file (option -f of iostat and sar),
2926 values are now computed in accordance with the interval given by
2927 the user on the command line.
2928 * Old '-o' option for iostat removed. Now iostat can save data
2929 into a file in a binary format and re-read them later (options
2930 '-o' and '-f') in the same way sar does.
2931 * Number of available processors now taken into account when
2932 retrieving CPU usage from /proc/stat.
2933 * Removed a bug that prevented 'sar -U' to work on SMP machines.
2934 * Fixed a bug that made per-CPU average usage wrong on SMP machines.
2935 * Use of option -U is now possible for sar when reading from a file
2936 even if the machine is not an SMP one.
2937 * Fixed a bug that prevented sar from re-reading stats saved in a file
2938 when -I or -U option had been used.
2939 * iostat modified to work on SMP machines.
2940 * Changed the formula used to display stats in order not to get
2941 numbers greater than UINT_MAX.
2942 * System name, release number and hostname are now saved in
2943 system activity files.
2944 * iostat now displays system name, release number and hostname

2948 * CREDITS file added.
2949 * NLS updated: German translation added.
2950 * Manual pages updated.
2951 * Makefile updated: Do not call msgfmt if NLS is not enabled.
