959 * sadf -H now displays the number of activities in file.
960 * nfsiostat manual page updated.
962 * README file updated.
965 2014/01/19: Version 10.2.1 - Sebastien Godard (sysstat <at> orange.fr)
966 * Added new --enable-copy-only option to configure script.
967 This option may be useful when creating sysstat package to
968 make sure that files are only copied to $DESTDIR and that
969 no service is activated (eg. for distro using systemd).
970 * pidstat: Add a new metric to pidstat I/O statistics:
971 per-task block I/O delays.
972 * Take $DESTDIR variable into account when installing sysstat
973 service used by systemd.

982 * pidstat: Added option -v, enabling the user to display the
983 number of threads and file descriptors associated with tasks.
984 * Stack stats displayed by "pidstat -s" were sometimes not
985 displayed for some processes although values had changed.
987 * pidstat can now display stats since system startup for a list
988 of processes given on the command line.
989 * pidstat -d now displays -1 for I/O stats values when the
990 process I/O file cannot be read (permission denied or file
992 * mpstat and pidstat commands now exit immediately when they
993 get a SIGINT signal during the first interval of time.
994 * [Alexander Troosh]: mpstat: Take into account the highest
995 processor number in mpstat output.
996 * Rearrange options displayed by sar -h (upper case option
997 should be displayed before its lower case counterpart).

999 will determine the size of data files created by sar/sadc.
1000 * Added xz-compressed target to Makefile.
1001 * pidstat manual page updated.
1005 2013/09/13: Version 10.1.7 - Sebastien Godard (sysstat <at> orange.fr)

1007 now gives the network interface utilization percentage.
1008 * Now use a lightweight static library having only the necessary
1009 functions to compile sysstat commands. This results in a
1010 size 25% to almost 45% smaller for some commands.

1024 by sadc only if option "-S XDISK" is used.
1025 * sar now collects all statistics (including partitions ones)
1026 when data are saved into a file with option -o.
1027 * [Yan Gao]: Update iostat manual page: Don't say that device
1028 saturation occurs when %util is close to 100% for devices
1029 serving multiple requests simultaneously.
1030 * Documentation fixes and updates.
1031 * Several manual pages updated (sar, sadc, sadf, sa1, sa2, sysstat).
1034 2013/06/09: Version 10.1.6 - Sebastien Godard (sysstat <at> orange.fr)

1036 be displayed with option -F.
1037 * DTD and XSD documents updated.
1038 * Code cleaned: Removed several unused constants from header files.
1039 * Sysstat command options can now be 'collapsed' (grouped) when
1040 not followed by an argument. So it's now possible for example
1041 to enter 'iostat -px 2 5' since no device name is given to
1042 option -p. This also concerns pidstat option -U.
1043 * Fixed type for "memfree" and "intr" elements in XSD document.
1044 * Removed functions used to count number of items from rd_stats.c
1045 and put them in a separate file (count.c).

1052 * mpstat now takes into account every interrupt per processor
1053 so that their number adds up to the number displayed for CPU "all".
1054 * [Peter Schiffer]: systemd unit file couldn't be installed
1055 because PKG_PROG_PKG_CONFIG macro wasn't expanded in configure
1056 script. This is now fixed.
1057 * [Benno Schulenberg]: Fixed a small inconsistency in pidstat
1059 * Cosmetic fixes in pidstat manual page.
1060 * NLS updated (de, eo, fi, fr, ja, nb, nl, ru, uk, vi).

1068 * sar now stops and displays its average stats when it receives
1070 * pidstat now displays task's UID for all tasks.
1071 * pidstat: -U option added. This option tells pidstat to display
1072 the username of the task instead of its UID. When this option is
1073 followed by a user name, then only tasks belonging to the
1074 specified user are displayed by pidstat.
1075 * pidstat manual page updated.
1076 * Now use sigaction() instead of signal() for signals handling
1077 to avoid portability problems.

1082 * Changed network counters (used by sar -n {DEV | EDEV }) to
1083 unsigned long long to keep in sync with current kernels.
1084 WARNING: This breaks compatibility with older sar data
1085 files format for network statistics.
1086 * Changed IPv4 counters (used by sar -n { IP | EIP}) to
1087 unsigned long long to keep in sync with current kernels.
1088 WARNING: This breaks compatibility with older sar data
1089 files format for IPv4 statistics.

1091 unsigned long long to keep in sync with current kernels.
1092 WARNING: This breaks compatibility with older sar data
1093 files format for IPv6 statistics.
1094 * [Peter Schiffer]: Added option -y to iostat. This option
1095 prevents iostat from displaying its first report with
1096 statistics since system boot.
1097 * [Peter Schiffer]: Increase NR_CPUS and NR_IRQS values.
1098 * [John Lau]: sadc didn't collect all its activities when

1137 to determine devices real name.
1138 * Part of 'sadf -H' output was written to stderr instead of
1139 stdout. This is now fixed.
1140 * WARNING: sadf: Option '-T' has been renamed into '-U', and
1141 option '-t' has been renamed into '-T'.
1142 * sadf: New option -t added. This option tells sadf to display
1143 the timestamps in the local time of the data file creator
1144 instead of UTC. The same option exists for sar.
1145 * [Peter Schiffer]: Various cosmetic changes in manual pages
1146 and usage messages displayed by sysstat commands.
1149 * sar, sadf and iostat manual pages updated.
1151 2012/05/16: Version 10.0.5 - Sebastien Godard (sysstat <at> orange.fr)

1489 * IPv6 support added. A bunch of new metrics have been added to
1490 sar, enabling the user to display statistics for IPv6 protocol
1491 family (IPv6, ICMPv6, UDPv6 and network sockets).
1492 * sadc updated: Option "-S IPV6" tells sadc to collect IPv6
1494 * sadf command updated to take into account IPv6 statistics.
1495 * Options -S (for sadc), -P (for mpstat, sar and sadf), -p (for
1496 iostat and pidstat) and -n and -I (for sar) now accept a list of
1497 comma-separated arguments.
1498 * [Ivana Varekova]: Make iostat display statistics for devices only
1499 (and not partitions) when not using its option -d. This was
1500 no longer possible with kernels 2.6.25 and later because iostat
1501 couldn't distinguish between devices and partitions any more.
1502 * iostat's options -x and -p are no longer mutually exclusive:
1503 Extended statistics are now available even for partitions with
1505 * iostat was unable to read stats from sysfs for devices who had
1506 a slash in their names (for example, iostat -p /dev/cciss/c0d0
1507 didn't work properly before). This is now fixed.

1542 option is used to display all activities horizontally on a
1544 * Fixed a bug in pidstat: When pidstat was used to monitor a
1545 process and all its threads (with pidstat's option -t), it
1546 could display weird values if the thread group leader terminated.
1547 * Header line displayed by sar, iostat, mpstat, pidstat and
1548 sadf -H now includes the number of CPU.

1552 * sar and sadf now check that CPU activity is available in file.
1553 * iostat's option -t now always displays the date and the time.
1554 * Added option "--disable-documentation" to ./configure. Using
1555 this option prevents documentation files (including manual
1556 pages) from being installed.

1576 swap space utilization. Option -r now only displays memory
1578 * Added %swpcad to sar -S (percentage of cached swap memory
1579 in relation to the amount of used swap space).
1580 * Added kbcommit and %commit to sar -r (amount and percentage
1581 of memory needed for current workload).
1582 * sadf -x now distinguishes between options -r and -R.
1583 * sadf command updated to take into account new fields
1584 (%guest, %swpcad, etc.)
1585 * [Ivana Varekova]: iostat now displays the total number of
1586 operations per second in the NFS report.
1587 * Fixed iostat so that %system (percentage of CPU utilization
1588 that occurred while executing at system level) also takes
1589 into account time spent to service interrupts and softirqs.
1590 * Added a missing header line for activities with multiple
1591 outputs displayed by sar (eg. sar -rR ...).
1592 * Makefile updated: There is now a dedicated target to install

1601 option "-u ALL". sadf has also been updated to be able to
1603 * mpstat can now display per-CPU interrupts statistics with its
1604 option "-I CPU". This was a feature available in sar that was
1605 removed in previous sysstat version.
1606 * mpstat uses now a separate option ("-I SUM") to display the
1607 total number of interrupts for each processor.
1608 * Option -A added to mpstat. This switch tells mpstat to display
1609 all possible activities.
1610 * NFS v4 support added to sar -n NFS(D). When both NFS v3 and
1611 NFS v4 are used, stats from NFS v3 and NFS v4 are added
1612 together [DEBIAN bug#434442].
1613 * Code cleaned: mpstat, iostat and pidstat now use the common
1614 functions from rd_stats.c to read CPU stats from /proc/stat;
1615 Computing extended disk statistics (service time, etc.) is now
1616 done in one place (common function used by iostat, sar, sadf).
1617 * All sysstat commands are made consistent with how parameters
1618 are interpreted: "COMMAND <interval>" now generates a report
1619 continuously, "COMMAND <interval> 0" causes an error,
1620 "COMMAND 0" displays a report since system startup
1621 [DEBIAN bug#475707].
1622 * Changed XML output for processes and context switches displayed
1623 by sadf -x to be consistent with output from sar.
1624 * mpstat and sar manual pages updated.
1625 * isag script updated.
1627 * DTD and XML Schema updated.

1631 WARNING: Daily data files format has changed, and is *not*
1632 compatible with the previous one! [0x2170]
1633 * sar, sadc and sadf heavily modified. It is now easier to add
1634 (or remove) activities since sar and sadc have been rewritten
1635 in a non-monolithic way with a generic design architecture.
1636 * Option -c removed from sar. Task creation and context switch
1637 activities are now merged and available with option -w.
1638 * sar no longer displays interrupts per processor statistics.
1639 This feature will be included in mpstat in next sysstat version.
1640 * Option -S added to sadc. This option replaces previous options
1641 -I or -d, and is used to select activities that should be
1642 collected and saved in file. It is even possible to
1643 select each activity collected by sadc.
1644 * Format of data files created by sar/sadc heavily modified.
1645 In some cases, it is now possible to add or remove activities
1646 while keeping a compatible format that can be read by a previous
1647 or future sysstat version.
1648 * sadf now only displays activities that have been explicitly
1650 * sar now checks that devices displayed by option -d are whole
1651 devices (and not partitions) using sysstat.ioconf configuration
1652 file. If this file is not found in its default directory, then
1653 sysstat looks for it in current directory.
1654 * gettextize entire usage() messages so that translators have
1656 * DTD and XML Schema updated.
1657 * Manual pages updated.
1658 * Crontab samples updated.

1664 per second in the NFS report.
1665 * [Tomas Mraz]: sadc now retries to write its buffers when the
1666 write() call has been interrupted by a signal.
1667 * Use setbuf() call instead of fflush() to indicate that data
1668 should not be buffered to stdout.
1669 * Option -h added to sadf. Used with options -d or -D, it
1670 indicates that all activities should be displayed horizontally
1671 on a single line of data.
1672 * sadf -d and sadf -D now display the list of fields for easier
1674 * sadf and iostat manual pages updated.
1675 * NLS updated: Chinese (simplified) translation added, other
1676 translations updated.

1690 /sys/devices/system/cpu directory [GENTOO bug# 207886].
1691 * Use __CPU_SETSIZE definition from <sched.h> instead of a
1692 static definition for the maximum number of CPUs (NR_CPUS).
1693 * Improved error messages displayed by sysstat's commands.
1694 * NLS updated: Finnish translation added, Dutch translation
1697 * Code cleaned and documented. Linux-like style applied to
1698 code source. Large functions split into smaller ones.

1912 2007/02/04: Version 7.0.4 - Sebastien Godard (sysstat <at> wanadoo.fr)
1913 * Removed linux/major.h from list of files included in ioconf.c.
1914 It was actually not used and also prevented sysstat from being
1915 compiled on GNU/kFreeBSD.
1916 * Sysstat scripts (sa1, sa2, sysstat) modified to enable the user
1917 to keep sar data for more than one month.
1918 * New parameter (COMPRESSAFTER) added to /etc/sysconfig/sysstat.
1919 It gives the number of days after which sar datafiles must be
1920 compressed to save disk space.
1921 * Replaced the word "Device" with "Filesystem" for iostat
1923 * iostat manual page updated.
1924 * Makefile updated: don't use a static list of languages to
1926 * "make install" now always install sysstat configuration file
1927 (default location is /etc/sysconfig).
1929 * Added my email address when displaying sysstat version.
1932 2006/12/03: Version 7.0.3 - Sebastien Godard (sysstat <at> wanadoo.fr)
1933 * iostat NFS statistics added.

1945 * sysstat spec file updated (gettext is now required).
1946 * NLS updated: Swedish translation added.
1947 * Manual pages updated.
1949 * CREDITS file updated.
1951 2006/09/17: Version 7.0.1 - Sebastien Godard (sysstat <at> wanadoo.fr)
1952 * Use now sysconf() function to get the size of a memory page
1953 instead of using header file <asm/page.h>.
1954 * The time specified with sadf options -s and -e is now always
1955 considered as given in local time. sadf output is now really
1956 consistent with that of sar.
1957 * Fixed a bug in the SREALLOC() macro which was causing sar to
1958 exit unexpectedly with this message: "realloc: Success".
1959 * Try to better guess when a stats title line has to be displayed
1961 * Makefile updated (SMP_RACE definition was no longer taken into
1962 account when compiling sadc).
1963 * sysstat spec file updated.
1964 * sar and sadf manual pages updated.
1966 * CREDITS file updated.
1968 2006/07/09: Version 7.0.0 - Sebastien Godard (sysstat <at> wanadoo.fr)
1969 * S_TIME_DEF_TIME environment variable added for sar, sadc and
1971 * Use now sysconf() function to get the number of clock ticks
1972 per second (HZ value) instead of using kernel include file

1981 * CREDITS file updated.
1983 2006/05/24: Version 6.1.3 - Sebastien Godard (sysstat <at> wanadoo.fr)
1984 WARNING: Daily data files format has changed, and is *not*
1985 compatible with the previous one! [0x2169]
1986 * Option -P can now be used with sar even on SMP machines where
1987 only one processor is available.
1988 * Small bug fixed for mpstat, where explicitly specifying
1989 processor 0 ("-P 0") could lead to incorrect output on UP
1991 * Option -D added to sadf: this option displays the contents of
1992 a data file in a database-friendly format with a timestamp
1993 expressed in seconds from the epoch.
1994 * sadf manual page updated.
1996 * CREDITS file updated.
1998 2006/04/23: Version 6.1.2 - Sebastien Godard (sysstat <at> wanadoo.fr)

2000 * sar can now display stats for newly created processes when
2001 option -x ALL or -X ALL is used.
2002 * iostat -x was displaying redundant information. It now
2003 displays amount of data read from or written to devices in
2004 sectors, kilobytes or megabytes depending on the switch used.
2005 * isag updated to keep up with current sar version.
2006 * sar and mpstat manual pages updated.
2009 2006/02/22: Version 6.1.1 - Sebastien Godard (sysstat <at> wanadoo.fr)

2011 compatible with the previous one! [0x2168]
2012 * New field added to sar: %steal.
2013 * The size of a long integer in now saved in the header of the
2014 data file created by sar. This size can be displayed with
2016 * Replaced the keyword "FULL" by the keyword "ALL" for sar -n
2017 to be consistent with remaining options.
2018 * Makefile updated (use implicit rules).
2019 * sar manual page updated.
2020 * CREDITS and FAQ files updated.
2022 2005/11/28: Version 6.0.2 - Sebastien Godard (sysstat <at> wanadoo.fr)
2023 * New field added to mpstat and iostat: %steal.
2024 * sar updated to take into account cpu steal time.
2025 * Off-by-one error in ioc_conv which was corrupting device names
2026 on 64-bit architecture [Debian bug #334305].
2027 * Binary RPM package now installs a sample crontab in /etc/cron.d.
2028 * Makefile updated (remove sysstat.cron.* during make clean -

2030 * sar now checks exit code from dup2() system calls.
2031 * Option -V now only displays sysstat version number.
2034 * Manual pages updated.
2036 2005/06/25: Version 6.0.1 - Sebastien Godard (sysstat <at> wanadoo.fr)
2037 * Fixed a memory leak in ioconf parsing functions used by sar
2039 * sar now displays its statistics to STDOUT in addition to saving
2040 them into the file when option -o has been entered on the
2042 * sar now recalculates number of system items (network interfaces,
2043 disks, serial lines, etc.) when a file rotation happens.
2044 * Make sar -b work again when used without option -d.
2045 * Small changes so that sysstat can be compiled with gcc-4.0.1.
2046 * sysstat updated so that it may be installed on Slackware.
2047 * sar manual page updated.
2048 * CREDITS file updated.
2051 2005/05/14: Version 6.0.0 - Sebastien Godard (sysstat <at> wanadoo.fr)
2052 WARNING: Daily data files format has changed, and is *not*
2053 compatible with the previous one! [0x2167]
2054 * Additional fields added to sar -y (TTY statistics). sar, sadf
2056 * sar -d now only reports for used devices (devices with non zero
2058 * Stricter sadf syntax checking: various output formats are now
2060 * Stricter iostat syntax checking: -k and -m options are now
2062 * iostat: option -m is now taken into account even when
2063 displaying extended statistics.
2064 * Fixed a bug that prevented iostat from displaying stats about
2065 devices that were unknown in sysstat.ioconf file.
2066 * iostat might display bogus sectors values when the corresponding
2067 kernel counters had overflown. This is now fixed.
2068 * "sadf datafile -- -A" should also display individual interrupts
2069 if available in datafile.
2070 * Fixed a bug that prevented sar -x from displaying stats about a
2071 process if it was after the first 256 processes in the process
2073 * Manual pages updated.
2074 * sa1 script always uses option -d in crontab.
2075 * sysstat.ioconf device configuration file updated.
2077 * FAQ and CREDITS files updated.
2080 2005/02/25: Version 5.1.5 - Sebastien Godard (sysstat <at> wanadoo.fr)
2081 * -x option added to sadf: it is now able to display the contents of
2082 a sar datafile in XML. The corresponding DTD (Document Type
2083 Definition) is included in the sysstat package.
2084 * Small code change so that sysstat may be compiled with gcc-4.0.
2085 * A few typos fixed in formulas used by sadf to display stats
2086 on machines where HZ<>100 (typos appeared in sysstat 5.1.4).
2087 * Fixed a bug in the stats displayed by sar -d.
2088 * Removed a false workaround in iostat: better show that the kernel
2089 is buggy rather than display a value that seems correct but which
2091 * Fixed sar -i option which might not select records at the specified
2092 interval on machines with multiple processors.
2093 * NLS updated and cleaned. Do no longer translate fields names (sar,
2094 iostat, etc.). Changed nb_NO.po and nn_NO.po files to nb.po and
2096 * Bug fixed in spec file: when installing sysstat i586 RPM package,
2097 sa1 and sa2 scripts were pointing to the wrong sadc location.
2098 * Now sar and sadc display the magic number when they meet an
2099 invalid system activity file.
2100 * sadf manual page updated.
2101 * sysstat RPM spec file is now included in source package.
2103 * FAQ, Makefile and CREDITS files updated.
2105 2005/01/02: Version 5.1.4 - Sebastien Godard (sysstat <at> wanadoo.fr)
2106 WARNING: Daily data files format has changed, and is *not*
2107 compatible with the previous one! [0x2166]
2108 * NFS client and server statistics added to sar.
2109 * sar -d now only reads stats for devices (and not partitions)
2110 from /proc/partitions. (This is what it was already doing with
2112 * Display routines from sadf merged, so that -ppc and -db
2113 always output the same values.
2114 * sadf updated to handle NFS statistics.
2115 * sadf can now display the header of a data file (option -H).
2116 * Define MAX_BLKDEV in ioconf.h if non-existent in <linux/major.h>.
2117 * sar now looks for sadc in one directory only, specified at
2118 compile time. Moreover it is now possible to have two different
2119 sysstat versions installed: sar knows where its sadc counterpart
2121 * sapath.in removed. SADC_PATH is defined in CONFIG file.
2122 * sar and sadf manual pages updated.
2123 * sysstat.ioconf file updated.
2124 * Fixed a bug in i386 RPM package, where sadc location was not
2125 consistent with that of sar. Spec file updated.
2128 * Various cosmetic changes (code and manual pages). Code cleaned.
2129 * FAQ and CREDITS files updated.
2131 2004/11/22: Version 5.1.3 - Sebastien Godard (sysstat <at> wanadoo.fr)
2132 WARNING: Daily data files format has changed, and is *not*
2133 compatible with the previous one! [0x2165]
2134 * Option -p added to sar: It enables sar (and also sadf) to
2135 display device names as they appear in /dev.
2136 * sysstat.ioconf support added.
2137 * New fields added to sar -d (more disk activities displayed):
2138 avgrq-sz, avgqu-sz, await, svctm, %util.
2139 * sadf updated to handle new disk activities.
2140 * I/O and transfer rate statistics as displayed by sar -b are
2141 available whatever the version of the kernel is (i.e. even on
2143 * Disk stats are read by sadc from /proc/stat only if they cannot
2144 be read from /proc/{partitions,diskstats}.
2145 * sadc: Some variables declarations moved around.
2146 * sar manual page updated.
2147 * Added workaround for EMC PowerPath driver bug to enable iostat
2148 to display proper device name.
2149 * Makefile updated: Use $@ and $< everywhere; 'make {iostat,mpstat}'
2150 work again; Create object files before linking; Removed unused
2151 IOS_DFLAGS variable; Use DESTDIR variable everywhere; Create
2152 libsysioc.a; Install sysstat.ioconf.
2154 * README and CREDITS files updated.
2156 2004/11/05: Version 5.1.2 - Sebastien Godard (sysstat <at> wanadoo.fr)
2157 * sar -d now also uses /proc/partitions to get its data.
2158 From now on sar -d looks in the following files in that order:
2159 /proc/diskstats, /proc/partitions, /proc/stat.
2160 * sadc writes disks data to file only if -d option is explicitly
2161 set on the command line.
2162 * sadc now reads individual interrupts data from /proc/stat only
2163 if -I option was entered on the command line.
2164 * 'sar -A' is now equivalent to 'sar -bBcdqrRuvwWy -I SUM -I XALL
2165 -n FULL -P ALL' (i.e. individual interrupts are also included
2167 * Option -m now tells iostat to display statistics in megabytes
2168 per second instead of blocks per second.
2169 * Make history (number of days to keep log files) configurable
2170 in /etc/sysconfig/sysstat file, which is used by sa2 script.
2171 * Now use Vixie cron to launch sadc when possible.
2172 * sadc, sa1 and sa2 may now be installed in another directory
2173 than ${PREFIX}/lib/sa. This is useful on 64-bit systems where
2174 the proper directory should be ${PREFIX}/lib64/sa.
2175 * When uninstalling sysstat, always delete sysstat script,
2176 config file and links in /etc tree. Also always delete
2178 * sysstat script now returns real exit code.
2179 * sar/sadc: Stricter syntax checking for -x and -X options use.
2180 * sysstat "*.sh" files renamed in "*.in".
2182 * sadc and sar manual pages updated.
2185 * CREDITS and README files updated.
2187 2004/10/09: Version 5.1.1 - Sebastien Godard (sysstat <at> wanadoo.fr)
2188 WARNING: Daily data files format has changed, and is *not*
2189 compatible with the previous one! [0x2164]
2190 * sar now reads CPU data, number of context switches, number
2191 of sectors and total number of interrupts as 64-bit unsigned
2192 values. It also reads the number of running processes as
2193 unsigned long instead of unsigned int.
2194 * sadf - System activity data formatter command added.
2195 * Options -h and -H removed from sar. "sar -h" is replaced by
2196 "sadf -p", and "sar -H" is replaced by "sadf -d". Read sadf
2197 manual page, as its syntax is a bit different from that of sar.
2198 * Common code for sar and sadf moved to sa_common.c file.
2199 * pid_stats members don't need to be aligned since these stats
2200 are not written to daily data files. Packing them saves some
2201 memory on 32-bit architectures.
2202 * No longer indicate that -x and -X are possible options for sadc.
2203 They are only useful when used as options for sar, not sadc.
2204 * Minor buffer overrun fixed in iostat.
2205 * Updated CPU header for iostat and mpstat: CPU used while executing
2206 at the system level is displayed as '%system' by iostat (like sar)
2207 and as '%sys' by mpstat.
2208 * sadf manual page added. Other manual pages updated.
2209 * Updated the GPL notices (the address of the FSF was wrong).
2212 * README, FAQ and CREDITS files updated.
2214 2004/08/09: Version 5.0.6 - Sebastien Godard (sysstat <at> wanadoo.fr)
2215 * The value for file-sz reported by sar -v was a number of free
2216 handles, and not a number of used ones! This is now fixed (and
2217 this is really now a number of _used_ file handles).
2218 * Now ask during config stage for the directory where sadc will
2219 be located. This may be useful for some systems where sadc
2220 needs to be installed in a specific location (e.g. on 64 bit
2221 s390 systems, the proper directory should be /usr/lib64/sa).
2222 * sa1 script updated: Use '-' to specify current daily data file
2223 instead of guessing its name using current date.
2224 * NLS updated: be consistent with GNU gettext standards.
2225 * iostat manual page updated.
2228 * CREDITS file updated.
2230 2004/06/08: Version 5.0.5 - Sebastien Godard (sysstat <at> wanadoo.fr)
2231 * Timestamp is no longer limited to 11 characters. This should
2232 avoid problems with somes locales (for example Japanese locale,
2233 where 'mojibake' used to be displayed by sar and mpstat sometimes).
2234 * Fixed a bug in sysstat RPM spec file (symlinks to sysstat
2235 script were wrong in /etc/rc.d directories).
2236 * sar now checks parameters for options -n, -s and -e more
2238 * NLS updated: Japanese translation added.
2239 * Various typos fixed in several files (manual pages, README, etc.)
2240 * CREDITS file updated.
2242 2004/05/20: Version 5.0.4 - Sebastien Godard (sysstat <at> wanadoo.fr)
2243 * When trying to lock file, sadc now checks for both EWOULDBLOCK
2244 and EAGAIN error codes to be portable.
2245 * sar could sometimes display a line whose time stamp was greater
2246 than the limit set by -e option. This is no longer possible.
2247 * The sadc command in sysstat.sh script had to be enclosed in
2248 quotes to work when called via 'su -c'.
2249 * The sysstat.sh script was sending the output of sadc command
2250 to stdout instead of the standard system activity file. This
2252 * Outfile must now be explicitly set to "-" for sadc to use the
2253 standard system activity file.
2255 * iostat manual page updated. Typo fixed in sadc manual page.
2256 * Fixed the "Save picture" option of isag script.
2258 2004/04/07: Version 5.0.3 - Sebastien Godard (sysstat <at> wanadoo.fr)
2259 * iostat now reads the number of sectors in /proc/diskstats or
2260 from sysfs as 64-bit unsigned values.
2261 * iostat and mpstat now read CPU data and the number of
2262 interrupts in /proc/stat as 64-bit unsigned values.
2263 * sar uses "%u" instead of "%d" to read unsigned integer
2264 values _everywhere_.
2265 * sar and sadc are now a little bit more verbose when dealing
2266 with invalid activity files.
2267 * Network interface name size is now read from include file
2270 * Slovak translation added. NLS updated.
2271 * Typo fixed in iostat manual page.
2272 * Makefile and CREDITS file updated.
2273 * isag upgraded to version 1.26 (isag package release 0.81.0).
2275 2004/03/10: Version 5.0.2 - Sebastien Godard (sysstat <at> wanadoo.fr)
2276 * iostat will _again_ look for statistics in /proc/partitions if
2277 available. Too many production servers are still using 2.2.x or
2278 2.4.x kernels and iostat must be able to display extended stats
2279 also for them (/proc/partitions support was removed in sysstat
2280 version 4.1.3). So now, iostat gets its statistics from the
2281 following sources in that order: /proc/diskstats, sysfs,
2282 /proc/partitions and then /proc/stat.
2283 * statistics are now read by iostat and mpstat as unsigned long
2284 instead of int to avoid integer overflow.
2285 * iostat should now handle properly the case when the 'weighted
2286 number of milliseconds spent doing I/Os' (read in sysfs or
2287 /proc/{partitions,diskstats}) decreases with time.
2288 * iostat manual page updated.
2289 * Minor temporary file vulnerability fixed in isag command.
2290 * README, FAQ and CREDITS files updated.
2291 * Author's email changed.
2293 2004/02/02: Version 5.0.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2294 * -L option added to sadc. Enable sadc to lock its output file
2295 to prevent multiple instances from writing to it at once.
2296 * sa1 and sysstat scripts updated to take advantage of -L option.
2297 * Handle the case where, under very special circumstances, STDOUT
2298 may become unavailable, and sar, iostat and mpstat are no longer
2299 able to display anything.
2300 * sadc as called in sysstat script also uses -F option to force
2301 the creation of daily data file.
2302 * sar, sadc and mpstat manual pages updated.
2304 * FAQ and CREDITS files updated.
2306 2003/11/09: Version 5.0.0 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2307 * New fields added to mpstat: %irq (%time spent servicing
2308 interrupts) and %soft (%time spent servicing softirqs).
2309 * sar and iostat updated to take into account time spent servicing
2310 interrupts and softirqs when displaying percentage of time
2312 * By default iostat now displays only statistics information for
2313 devices that are used by the system. You should now use the ALL
2314 keyword to tell iostat to display statistics for every device
2315 including those that have never been used.
2316 * The file version.h is now dynamically created. sysstat's version
2317 number is now only recorded in the Makefile.
2318 * sar manual page updated: beginning with kernels 2.4 and later,
2319 pgpgin and pgpgout statistics are in kilobytes and not in
2320 blocks (see linux-2.4/fs/proc/proc_misc.c and
2321 linux-2.6/mm/page_alloc.c).
2322 * iostat and mpstat manual pages updated.
2323 * Makefile updated: don't process NLS files if they are up-to-date.
2324 * sysstat's RPM spec file updated to enable clean, non-root builds.
2326 * FAQ and CREDITS files updated.
2328 2003/09/28: Version 4.1.7 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2329 WARNING: Daily data files format has changed, and is *not*
2330 compatible with the previous one! [0x2163]
2331 * /proc/diskstats is now the preferred source for iostat to get its
2332 statistics. If non-existent, iostat falls back on sysfs then
2334 * In addition to devices, partitions can also be entered on the
2335 command line for iostat providing that option -x is not used.
2336 * /dev prefix has been removed from device name displayed by iostat -x.
2337 * sar -d now looks for disks statistics in /proc/diskstats with
2339 * sar uses /proc/vmstat file with post 2.5 kernels to find paging
2340 and swapping statistics.
2341 * activepg, inadtypg, inaclnpg and inatarpg stats removed from
2342 sar -B report (they were not really useful).
2343 * sar -B now displays the number of page faults made by the system
2344 (pgfault/s and pgmajflt/s).
2345 * Stat on shared memory removed from sar -r and sar -R (this stat
2346 was no longer maintained by the kernel since 2.4 because of
2347 performance problems).
2348 * Cached swap statistic information added to sar -r.
2349 * sar -d now displays separate statistics for sectors that are
2350 read from or written to devices.
2351 * %file-sz (percentage of used file handles) is no longer displayed
2352 by sar -v, since the upper limit for the number of open files
2353 will self-scale with 2.6 kernels.
2354 * sar now looks more aggressively for network devices in /proc/net/dev.
2355 * Heading spaces in network interface names removed (sar -n).
2356 * Fixed a problem reading /proc/interrupts when there are a lot
2357 of CPUs (mpstat, sadc).
2358 * NR_IRQS value increased to 256, since IA64 supports 256 irqs
2360 * Some stats counters are now read as unsigned long instead of
2361 unsigned int (pgpgin, pgpgout, pswpin, pswpout, irq_sum).
2362 * sar and iostat manual pages updated.
2363 * FAQ, README and CREDITS files updated.
2366 2003/08/20: Version 4.1.6 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2367 WARNING: Daily data files format has changed, and is *not*
2368 compatible with the previous one! [0x2162]
2369 * Machine uptime calculation is now optimized on SMP machines
2370 to minimize the consequences if an overflow condition happens.
2371 Especially useful when asking for stats since system boot.
2372 * -F option added to sadc. Useful to force the creation of the
2373 daily data file: an already existing file with a wrong format
2374 will be truncated by sadc if this option is used.
2375 * sa1 script now calls sadc with -F option.
2376 * The processor number to which the process is attached was no
2377 longer displayed by sar -x. Make it appear again.
2378 * CPU usage for processes, as displayed by sar -x and sar -X, should
2379 now be correct on machines where HZ <> 100 (e.g. IA64 architecture).
2380 * iostat still assumed that jiffies were 100ths of a second in some
2381 places. Now use Linux HZ definition *everywhere*.
2382 * The average I/O requests queue length as displayed by iostat -x was
2383 wrongly calculated. This is now fixed.
2384 * Manual pages updated.
2386 * Cosmetic changes in various parts of the code.
2387 * FAQ, README and CREDITS files updated.
2389 2003/07/21: Version 4.1.5 - Sebastien Godard <sebastien.godard@wanadoo.fr>

2391 compatible with the previous one! Delete existing data files
2392 in /var/log/sa directory! [0x2161]
2393 * 'sar -x <pid>' and 'sar -X <pid>' work again.
2394 * sar had a longstanding bug that prevented option -P from
2395 working properly if the machine had more than 32 processors.
2397 * Fixed a bug introduced in 4.1.2, which made some LINUX RESTART
2398 messages to not be displayed by sar.
2399 * sar now uses bitmap of char instead of int to avoid endianness
2401 * sar can now handle a huge number of processors, serial lines and

2408 in /var/log/sa directory! [0x2160]
2409 * Fixed the way overflow conditions were handled by sar for
2410 interfaces counters.
2411 * On really big machines with 100 GB of memory or more, the values
2412 read by sadc in /proc/meminfo would get truncated and cause havoc
2413 in the calculations. This is now fixed.
2414 * iostat and sar can now read many more disk entries in /proc/stat if
2416 * Option "-x SUM" removed for sar. It was used to tell sar to display
2417 the total number of minor and major faults made by the system.
2418 Unfortunately, the calculation was tricky, and the results were
2420 * NLS updated. Polish translation added. Also proper charset and
2421 encoding declarations added to fix msgfmt warnings and allow
2422 gettext to recode between various charsets (e.g. German
2423 translation will be shown properly both with

2431 * Disks arrays in iostat are now dynamically sized.
2432 * iostat: sysfs is now used in preference to /proc/stat if available.
2433 * iostat will no longer look for statistics in /proc/partitions.
2434 sysfs filesystem must now be available for iostat to get its
2435 extended stats (post 2.5 kernels).

2448 in /var/log/sa directory! [0x215f]
2449 * sar -q now also displays load average for the past 15 minutes.
2450 * -P option added to sar. This option enables sar to display
2451 stats on a per processor basis. Options -U and '-I PROC' are
2452 deprecated. 'sar -U ALL' is replaced by 'sar -u -P ALL', and
2453 'sar -I PROC' by 'sar -I SUM -P ALL'.
2454 * Fixed iowait value displayed by sar on SMP machines with pre 2.5
2456 * When displaying CPU utilization on SMP machines, sar now
2457 recalculates the interval based on current CPU's tick count.
2458 * Always check that the number of CPUs has not increased when
2459 reading /proc/stat (sadc, mpstat).
2460 * sadc: Don't assume that the first line in /proc/net/sockstat
2461 concerns sockets. Check it!
2462 * Serial lines are ignored by sadc for every kind of kernels
2463 (UP, SMP...) if SMP_RACE is defined.
2464 SMP_RACE is no longer defined by default in RPM packages.
2465 * Code cleaned: Dead code removed in iostat.c, some lines longer
2466 than 80 chars folded, etc.

2495 2002/08/04: Version 4.0.6 - Sebastien Godard <sebastien.godard@wanadoo.fr>
2496 * mpstat now uses a bitmap of char instead of int to avoid endianness
2497 problems. As a consequence, mpstat should now work on PowerMac
2499 * CPU activity as displayed by mpstat -P for a given processor was
2500 in a wrong range on SMP machines (e.g. 0-50% for a dual processor
2502 * Missing bitmap initialization fixed in mpstat.c.

2615 * Code cleaned: Now always use 'double' numbers instead of the
2616 INT_PART, INT_VAL, DEC_PART and DEC_VAL macros.
2617 * Don't assume that jiffies are 100ths of a second. Use Linux
2618 HZ definition instead.

2626 reading /proc/stat file with 2.4 kernels (sar -b). This is now
2628 * iostat command is no longer able to save its data to a file.
2629 In fact, iostat has never been supposed to work that way, and I
2630 have never really maintained this option.
