832 * [Ivana Varekova]: Make iostat display statistics for devices only
833 (and not partitions) when not using its option -d. This was
834 no longer possible with kernels 2.6.25 and later because iostat
835 couldn't distinguish between devices and partitions any more.
836 * iostat's options -x and -p are no longer mutually exclusive:
837 Extended statistics are now available even for partitions with
839 * iostat was unable to read stats from sysfs for devices who had
840 a slash in their names (for example, iostat -p /dev/cciss/c0d0
841 didn't work properly before). This is now fixed.
842 * [Amir Rapson]: Fixed a bug in iostat where %CPU spent

915 of memory needed for current workload).
916 * sadf -x now distinguishes between options -r and -R.
917 * sadf command updated to take into account new fields
918 (%guest, %swpcad, etc.)
919 * [Ivana Varekova]: iostat now displays the total number of
920 operations per second in the NFS report.

938 option "-I CPU". This was a feature available in sar that was
939 removed in previous sysstat version.
940 * mpstat uses now a separate option ("-I SUM") to display the
941 total number of interrupts for each processor.
942 * Option -A added to mpstat. This switch tells mpstat to display
943 all possible activities.
944 * NFS v4 support added to sar -n NFS(D). When both NFS v3 and
945 NFS v4 are used, stats from NFS v3 and NFS v4 are added
946 together [DEBIAN bug#434442].
947 * Code cleaned: mpstat, iostat and pidstat now use the common
948 functions from rd_stats.c to read CPU stats from /proc/stat;
949 Computing extended disk statistics (service time, etc.) is now
950 done in one place (common function used by iostat, sar, sadf).
951 * All sysstat commands are made consistent with how parameters
952 are interpreted: "COMMAND <interval>" now generates a report
953 continuously, "COMMAND <interval> 0" causes an error,
954 "COMMAND 0" displays a report since system startup
956 * Changed XML output for processes and context switches displayed
957 by sadf -x to be consistent with output from sar.
958 * mpstat and sar manual pages updated.
959 * isag script updated.

965 WARNING: Daily data files format has changed, and is *not*
966 compatible with the previous one! [0x2170]
967 * sar, sadc and sadf heavily modified. It is now easier to add
968 (or remove) activities since sar and sadc have been rewritten
969 in a non-monolithic way with a generic design architecture.
970 * Option -c removed from sar. Task creation and context switch
971 activities are now merged and available with option -w.
972 * sar no longer displays interrupts per processor statistics.
973 This feature will be included in mpstat in next sysstat version.
974 * Option -S added to sadc. This option replaces previous options
975 -I or -d, and is used to select activities that should be
976 collected and saved in file. It is even possible to
977 select each activity collected by sadc.
978 * Format of data files created by sar/sadc heavily modified.
979 In some cases, it is now possible to add or remove activities
980 while keeping a compatible format that can be read by a previous
981 or future sysstat version.
982 * sadf now only displays activities that have been explicitly

998 per second in the NFS report.
999 * [Tomas Mraz]: sadc now retries to write its buffers when the
1000 write() call has been interrupted by a signal.
1001 * Use setbuf() call instead of fflush() to indicate that data
1002 should not be buffered to stdout.
1003 * Option -h added to sadf. Used with options -d or -D, it
1004 indicates that all activities should be displayed horizontally
1005 on a single line of data.
1006 * sadf -d and sadf -D now display the list of fields for easier
1008 * sadf and iostat manual pages updated.
1009 * NLS updated: Chinese (simplified) translation added, other
1010 translations updated.

1516 * sadc and sar manual pages updated.
1519 * CREDITS and README files updated.
1521 2004/10/09: Version 5.1.1 - Sebastien Godard (sysstat <at> wanadoo.fr)
1522 WARNING: Daily data files format has changed, and is *not*
1523 compatible with the previous one! [0x2164]
1524 * sar now reads CPU data, number of context switches, number
1525 of sectors and total number of interrupts as 64-bit unsigned
1526 values. It also reads the number of running processes as
1527 unsigned long instead of unsigned int.
1528 * sadf - System activity data formatter command added.
1529 * Options -h and -H removed from sar. "sar -h" is replaced by
1530 "sadf -p", and "sar -H" is replaced by "sadf -d". Read sadf
1531 manual page, as its syntax is a bit different from that of sar.
1532 * Common code for sar and sadf moved to sa_common.c file.
1533 * pid_stats members don't need to be aligned since these stats
1534 are not written to daily data files. Packing them saves some
1535 memory on 32-bit architectures.
1536 * No longer indicate that -x and -X are possible options for sadc.
1537 They are only useful when used as options for sar, not sadc.
1538 * Minor buffer overrun fixed in iostat.
1539 * Updated CPU header for iostat and mpstat: CPU used while executing
1540 at the system level is displayed as '%system' by iostat (like sar)
1541 and as '%sys' by mpstat.
1542 * sadf manual page added. Other manual pages updated.
1543 * Updated the GPL notices (the address of the FSF was wrong).
1546 * README, FAQ and CREDITS files updated.
1548 2004/08/09: Version 5.0.6 - Sebastien Godard (sysstat <at> wanadoo.fr)
1549 * The value for file-sz reported by sar -v was a number of free
1550 handles, and not a number of used ones! This is now fixed (and
1551 this is really now a number of _used_ file handles).
1552 * Now ask during config stage for the directory where sadc will
1553 be located. This may be useful for some systems where sadc
1554 needs to be installed in a specific location (e.g. on 64 bit
1555 s390 systems, the proper directory should be /usr/lib64/sa).
1556 * sa1 script updated: Use '-' to specify current daily data file
1557 instead of guessing its name using current date.
1558 * NLS updated: be consistent with GNU gettext standards.
1559 * iostat manual page updated.
1562 * CREDITS file updated.
1564 2004/06/08: Version 5.0.5 - Sebastien Godard (sysstat <at> wanadoo.fr)
1565 * Timestamp is no longer limited to 11 characters. This should
1566 avoid problems with somes locales (for example Japanese locale,
1567 where 'mojibake' used to be displayed by sar and mpstat sometimes).
1568 * Fixed a bug in sysstat RPM spec file (symlinks to sysstat
1569 script were wrong in /etc/rc.d directories).
1570 * sar now checks parameters for options -n, -s and -e more
1572 * NLS updated: Japanese translation added.
1573 * Various typos fixed in several files (manual pages, README, etc.)
1574 * CREDITS file updated.
1576 2004/05/20: Version 5.0.4 - Sebastien Godard (sysstat <at> wanadoo.fr)
1577 * When trying to lock file, sadc now checks for both EWOULDBLOCK
1578 and EAGAIN error codes to be portable.
1579 * sar could sometimes display a line whose time stamp was greater
1580 than the limit set by -e option. This is no longer possible.
1581 * The sadc command in sysstat.sh script had to be enclosed in
1582 quotes to work when called via 'su -c'.
1583 * The sysstat.sh script was sending the output of sadc command
1584 to stdout instead of the standard system activity file. This
1586 * Outfile must now be explicitly set to "-" for sadc to use the
1587 standard system activity file.
1589 * iostat manual page updated. Typo fixed in sadc manual page.
1590 * Fixed the "Save picture" option of isag script.
1592 2004/04/07: Version 5.0.3 - Sebastien Godard (sysstat <at> wanadoo.fr)
1593 * iostat now reads the number of sectors in /proc/diskstats or
1594 from sysfs as 64-bit unsigned values.
1595 * iostat and mpstat now read CPU data and the number of
1596 interrupts in /proc/stat as 64-bit unsigned values.
1597 * sar uses "%u" instead of "%d" to read unsigned integer
1598 values _everywhere_.
1599 * sar and sadc are now a little bit more verbose when dealing
1600 with invalid activity files.
1601 * Network interface name size is now read from include file
1604 * Slovak translation added. NLS updated.
1605 * Typo fixed in iostat manual page.
1606 * Makefile and CREDITS file updated.
1607 * isag upgraded to version 1.26 (isag package release 0.81.0).
1609 2004/03/10: Version 5.0.2 - Sebastien Godard (sysstat <at> wanadoo.fr)
1610 * iostat will _again_ look for statistics in /proc/partitions if
1611 available. Too many production servers are still using 2.2.x or
1612 2.4.x kernels and iostat must be able to display extended stats
1613 also for them (/proc/partitions support was removed in sysstat
1614 version 4.1.3). So now, iostat gets its statistics from the
1615 following sources in that order: /proc/diskstats, sysfs,
1616 /proc/partitions and then /proc/stat.
1617 * statistics are now read by iostat and mpstat as unsigned long
1618 instead of int to avoid integer overflow.
1619 * iostat should now handle properly the case when the 'weighted
1620 number of milliseconds spent doing I/Os' (read in sysfs or
1621 /proc/{partitions,diskstats}) decreases with time.
1622 * iostat manual page updated.
1623 * Minor temporary file vulnerability fixed in isag command.
1624 * README, FAQ and CREDITS files updated.
1625 * Author's email changed.
1627 2004/02/02: Version 5.0.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1628 * -L option added to sadc. Enable sadc to lock its output file
1629 to prevent multiple instances from writing to it at once.
1630 * sa1 and sysstat scripts updated to take advantage of -L option.
1631 * Handle the case where, under very special circumstances, STDOUT
1632 may become unavailable, and sar, iostat and mpstat are no longer
1633 able to display anything.
1634 * sadc as called in sysstat script also uses -F option to force
1635 the creation of daily data file.
1636 * sar, sadc and mpstat manual pages updated.
1638 * FAQ and CREDITS files updated.
1640 2003/11/09: Version 5.0.0 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1641 * New fields added to mpstat: %irq (%time spent servicing
1642 interrupts) and %soft (%time spent servicing softirqs).
1643 * sar and iostat updated to take into account time spent servicing
1644 interrupts and softirqs when displaying percentage of time
1646 * By default iostat now displays only statistics information for
1647 devices that are used by the system. You should now use the ALL
1648 keyword to tell iostat to display statistics for every device
1649 including those that have never been used.
1650 * The file version.h is now dynamically created. sysstat's version
1651 number is now only recorded in the Makefile.
1652 * sar manual page updated: beginning with kernels 2.4 and later,
1653 pgpgin and pgpgout statistics are in kilobytes and not in
1654 blocks (see linux-2.4/fs/proc/proc_misc.c and
1655 linux-2.6/mm/page_alloc.c).
1656 * iostat and mpstat manual pages updated.
1657 * Makefile updated: don't process NLS files if they are up-to-date.
1658 * sysstat's RPM spec file updated to enable clean, non-root builds.
1660 * FAQ and CREDITS files updated.
1662 2003/09/28: Version 4.1.7 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1663 WARNING: Daily data files format has changed, and is *not*
1664 compatible with the previous one! [0x2163]
1665 * /proc/diskstats is now the preferred source for iostat to get its
1666 statistics. If non-existent, iostat falls back on sysfs then
1668 * In addition to devices, partitions can also be entered on the
1669 command line for iostat providing that option -x is not used.
1670 * /dev prefix has been removed from device name displayed by iostat -x.
1671 * sar -d now looks for disks statistics in /proc/diskstats with
1673 * sar uses /proc/vmstat file with post 2.5 kernels to find paging
1674 and swapping statistics.
1675 * activepg, inadtypg, inaclnpg and inatarpg stats removed from
1676 sar -B report (they were not really useful).
1677 * sar -B now displays the number of page faults made by the system
1678 (pgfault/s and pgmajflt/s).
1679 * Stat on shared memory removed from sar -r and sar -R (this stat
1680 was no longer maintained by the kernel since 2.4 because of
1681 performance problems).
1682 * Cached swap statistic information added to sar -r.
1683 * sar -d now displays separate statistics for sectors that are
1684 read from or written to devices.
1685 * %file-sz (percentage of used file handles) is no longer displayed
1686 by sar -v, since the upper limit for the number of open files
1687 will self-scale with 2.6 kernels.
1688 * sar now looks more aggressively for network devices in /proc/net/dev.
1689 * Heading spaces in network interface names removed (sar -n).
1690 * Fixed a problem reading /proc/interrupts when there are a lot
1691 of CPUs (mpstat, sadc).
1692 * NR_IRQS value increased to 256, since IA64 supports 256 irqs
1694 * Some stats counters are now read as unsigned long instead of
1695 unsigned int (pgpgin, pgpgout, pswpin, pswpout, irq_sum).
1696 * sar and iostat manual pages updated.
1697 * FAQ, README and CREDITS files updated.
1700 2003/08/20: Version 4.1.6 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1701 WARNING: Daily data files format has changed, and is *not*
1702 compatible with the previous one! [0x2162]
1703 * Machine uptime calculation is now optimized on SMP machines
1704 to minimize the consequences if an overflow condition happens.
1705 Especially useful when asking for stats since system boot.
1706 * -F option added to sadc. Useful to force the creation of the
1707 daily data file: an already existing file with a wrong format
1708 will be truncated by sadc if this option is used.
1709 * sa1 script now calls sadc with -F option.
1710 * The processor number to which the process is attached was no
1711 longer displayed by sar -x. Make it appear again.
1712 * CPU usage for processes, as displayed by sar -x and sar -X, should
1713 now be correct on machines where HZ <> 100 (e.g. IA64 architecture).
1714 * iostat still assumed that jiffies were 100ths of a second in some
1715 places. Now use Linux HZ definition *everywhere*.
1716 * The average I/O requests queue length as displayed by iostat -x was
1717 wrongly calculated. This is now fixed.
1718 * Manual pages updated.
1720 * Cosmetic changes in various parts of the code.
1721 * FAQ, README and CREDITS files updated.
1723 2003/07/21: Version 4.1.5 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1724 WARNING: Daily data files format has changed, and is *not*
1725 compatible with the previous one! Delete existing data files
1726 in /var/log/sa directory! [0x2161]
1727 * 'sar -x <pid>' and 'sar -X <pid>' work again.
1728 * sar had a longstanding bug that prevented option -P from
1729 working properly if the machine had more than 32 processors.
1731 * Fixed a bug introduced in 4.1.2, which made some LINUX RESTART
1732 messages to not be displayed by sar.
1733 * sar now uses bitmap of char instead of int to avoid endianness
1735 * sar can now handle a huge number of processors, serial lines and
1739 2003/07/01: Version 4.1.4 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1740 WARNING: Daily data files format has changed, and is *not*
1741 compatible with the previous one! Delete existing data files
1742 in /var/log/sa directory! [0x2160]
1743 * Fixed the way overflow conditions were handled by sar for
1744 interfaces counters.
1745 * On really big machines with 100 GB of memory or more, the values
1746 read by sadc in /proc/meminfo would get truncated and cause havoc
1747 in the calculations. This is now fixed.
1748 * iostat and sar can now read many more disk entries in /proc/stat if
1750 * Option "-x SUM" removed for sar. It was used to tell sar to display
1751 the total number of minor and major faults made by the system.
1752 Unfortunately, the calculation was tricky, and the results were
1754 * NLS updated. Polish translation added. Also proper charset and
1755 encoding declarations added to fix msgfmt warnings and allow
1756 gettext to recode between various charsets (e.g. German
1757 translation will be shown properly both with
1758 LANG=de_DE.ISO-8859-1, and LANG=de_DE.UTF-8)
1759 * Code 'sanitization'.
1760 * Manual pages updated.
1761 * README and FAQ files updated.
1763 2003/05/08: Version 4.1.3 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1764 * iostat should now be fully 2.5/2.6 kernel compliant.
1765 * Disks arrays in iostat are now dynamically sized.
1766 * iostat: sysfs is now used in preference to /proc/stat if available.
1767 * iostat will no longer look for statistics in /proc/partitions.
1768 sysfs filesystem must now be available for iostat to get its
1769 extended stats (post 2.5 kernels).
1770 * iostat: Devices for which statistics are requested can now be entered
1771 on the command line even if option -x is not used.
1772 * Usage messages updated.
1773 * Manual pages updated.
1774 * Code cleaned (dk_drive_sum removed in iostat, long lines folded,
1775 functions split in smaller parts, etc.)
1776 * NLS updated. Romanian translation added.
1777 * isag upgraded to version 1.22.
1779 2003/01/24: Version 4.1.2 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1780 WARNING: Daily data files format has changed, and is *not*
1781 compatible with the previous one! Delete existing data files
1782 in /var/log/sa directory! [0x215f]
1783 * sar -q now also displays load average for the past 15 minutes.
1784 * -P option added to sar. This option enables sar to display
1785 stats on a per processor basis. Options -U and '-I PROC' are
1786 deprecated. 'sar -U ALL' is replaced by 'sar -u -P ALL', and
1787 'sar -I PROC' by 'sar -I SUM -P ALL'.
1788 * Fixed iowait value displayed by sar on SMP machines with pre 2.5
1790 * When displaying CPU utilization on SMP machines, sar now
1791 recalculates the interval based on current CPU's tick count.
1792 * Always check that the number of CPUs has not increased when
1793 reading /proc/stat (sadc, mpstat).
1794 * sadc: Don't assume that the first line in /proc/net/sockstat
1795 concerns sockets. Check it!
1796 * Serial lines are ignored by sadc for every kind of kernels
1797 (UP, SMP...) if SMP_RACE is defined.
1798 SMP_RACE is no longer defined by default in RPM packages.
1799 * Code cleaned: Dead code removed in iostat.c, some lines longer
1800 than 80 chars folded, etc.
1801 * sar manual page updated.

1807 compatible with the previous one! Delete existing data files
1808 in /var/log/sa directory! [0x215e]
1809 * sar -u/-U, iostat and mpstat can now display time spent in
1810 I/O wait mode (with 2.5 kernels and above).
1811 * Values like -1 and -2 are no longer aliases for keywords
1812 ALL and XALL (sar -U, sar -I, mpstat -P).
1813 * Buglet fixed in iostat.h.
1814 * LC_CTYPE needs to be set, or it will emit messages with ?????? only
1815 on some locales, especially ja_JP.eucJP
1816 * sar, mpstat and iostat manual pages updated.
1818 * CREDITS file updated.
1819 * Typo removed in FAQ file.
1821 2002/11/13: Version 4.0.7 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1822 * Make data for timestamp 00:00:00 appear in one of the daily data
1823 files when sar/sadc rotates its output file.
1824 * Take out check for non SMP configuration when asking for
1826 * sargon script updated.
1829 2002/08/04: Version 4.0.6 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1830 * mpstat now uses a bitmap of char instead of int to avoid endianness
1831 problems. As a consequence, mpstat should now work on PowerMac
1833 * CPU activity as displayed by mpstat -P for a given processor was
1834 in a wrong range on SMP machines (e.g. 0-50% for a dual processor
1836 * Missing bitmap initialization fixed in mpstat.c.
1837 * Configuration script updated.
1840 2002/05/12: Version 4.0.5 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1841 * Average wait times and service times as displayed by iostat -x
1842 were wrong by a factor of 10. This is now fixed.
1843 * Linux RESTART messages must now be in the interval specified by
1844 -s/-e options to be displayed by sar.
1845 * Fixed a small bug that affected the timestamp for RESTART messages
1846 displayed by sar -h when option -t was used.
1847 * sar -H now displays its data in local time instead of UTC when
1849 * sargon shell script added.
1850 * Created a contrib directory, including sargon and isag commands.
1854 * sar manual page updated.
1856 2002/04/07: Version 4.0.4 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1857 * iostat is now able to display I/O activity in kB/s with 2.4.x
1858 kernels (option -k).
1859 * Fixed a typo in 'sar -W -h' output.
1860 * Try to handle the case when some parameters in /proc/net/dev
1861 may overflow ULONG_MAX.
1862 * 'sar -d' now displays sectors per second instead of blocks
1864 * iostat and sar manual pages updated.

1879 2001/09/22: Version 4.0.2 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1880 * CPU usage, as displayed by iostat, mpstat and sar, should now
1881 be OK on machines where HZ <> 100 (e.g. IA64 architecture).
1882 * MAX_PART constant set to 256 in iostat.h.
1883 * "-H" database friendly option added to sar.
1884 * Better disks and network interfaces management (both may be
1885 registered dynamically).
1886 * Made options "-s" and "-e" work when option "-h" is used.
1887 * isag upgraded to version 1.17.
1888 * isag installation is now optional and can be chosen at config stage.
1889 * Now try to install man pages in ${PREFIX}/share/man instead of
1891 * sa2 shell script updated.
1892 * Configuration script updated.
1893 * sar manual page updated.
1894 * NLS updated: Norwegian translation added.
1896 2001/06/24: Version 4.0.1 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1897 * Files created by sa2 shell script were world writable. This is
1899 * sa2.sh shell script updated: only remove sa?? and sar?? files.
1900 * Don't use PAGE_SHIFT since it no longer necessarily exists in
1901 <asm/page.h>. Compute it using page size instead.
1902 * Cosmetic changes for iostat.
1903 * NLS updated: Afrikaans translation added.
1905 2001/04/08: Version 4.0.0 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1906 * Better network interfaces handling. Now take into account the
1907 fact that they may be registered/unregistered dynamically.
1908 * Changed formula used to display statistics in order to avoid
1909 overflow conditions.
1910 * Fixed a bug in iostat, where the %util value scaled incorrectly.
1911 * Better long file names management by iostat.
1912 * mpstat and sar no longer periodically display the title line when
1913 stdout has been redirected to a pipe or a file.
1914 * sa2.sh shell script updated: Now exec sadc.
1915 * Configuration script updated.
1918 * Manual pages updated.
1919 * isag command updated.

1922 WARNING: Daily data files format has changed, and is *not*
1923 compatible with the previous one! Delete existing data files
1924 in /var/log/sa directory! [0x215d]
1925 * New paging statistics added (sar -B). Kernel 2.4 only.
1926 * Load averages and queue length statistics added (option -q for sar).
1927 * Per device statistics added (option -d for sar). Kernel 2.4 only.
1928 * Better accuracy when computing average for some statistics.
1929 * Display all the contents of a daily data file when the count
1930 parameter is not given on the command line.
1931 * Check sar command line options more aggressively.
1932 * iostat no longer freezes if -c and -d options are used together.
1933 * Fixed a bug that prevented iostat from displaying more than an
1934 average of three devices with 2.4 kernels (a buffer was too small).
1935 * Check added to ensure that sar and sadc commands are consistent.
1936 * sar manual page updated.
1938 * Code cleaned (use smaller subroutines).
1940 * isag command updates.
1942 2001/02/11: Version 3.3.5 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1943 * iostat command improved. Take now full advantage of Stephen
1944 Tweedie's I/O accounting patch to display extended statistics
1946 * The default value for the count parameter of the sar command is
1947 now 1 (this is how sar works with other Un*xes...). A value of
1948 0 will indicate that reports are to be generated continuously.
1949 * Code cleaned: Now always use 'double' numbers instead of the
1950 INT_PART, INT_VAL, DEC_PART and DEC_VAL macros.
1951 * Don't assume that jiffies are 100ths of a second. Use Linux
1952 HZ definition instead.
1953 * NLS updated (small fix).
1954 * sar and iostat manual pages updated.
1955 * isag (Interactive System Activity Graph) command added.
1958 2001/01/26: Version 3.3.4 - Sebastien Godard <sebastien.godard@wanadoo.fr>
1959 * Disk I/O statistics for the last device were counted twice when
1960 reading /proc/stat file with 2.4 kernels (sar -b). This is now
1962 * iostat command is no longer able to save its data to a file.
1963 In fact, iostat has never been supposed to work that way, and I
1964 have never really maintained this option.
1965 * iostat now also works with 2.4 kernels. It can handle the format
1966 of the /proc/stat file for both 2.2 and 2.4 kernels.
1967 * sar now reports statistics on allocated disk quotas entries
1968 instead of on used ones (sar -v).

1973 compatible with the previous one! Delete existing data files
1974 in /var/log/sa directory!
1975 * Disk usage displayed by iostat on SMP machines was wrong. This
1977 * iostat command cleaned: All the statistics not implemented in
1978 the standard Linux kernel have been removed (tty, iowait...).
1979 * sar can now handle I/O and transfer rate statistics with both
1980 2.2.x and 2.4.x Linux kernels (-b option).
1981 * Removed %inode-sz that was displayed by sar -v, since the file
1982 inode-max in /proc/sys/fs no longer exists in Linux 2.4.
1983 The new 2.4.x kernels now seem to be able to allocate inode
1984 structures dynamically, and to free them when necessary (see
1986 * Removed statistics on highest in-used sockets. Relevant
1987 counters have disappeared from sockstat file in /proc/net
1988 for 2.4 kernels (sar -n SOCK).
1989 * Added statistics on IP datagram fragments (sar -n SOCK).

2012 processing commands like awk.
2013 * Manual page updated for sar.
2014 * iostat now writes KB (for kilobytes) instead of Kb, which could
2015 have been interpreted as kilobits...

2121 reading stats back from a file.
2122 * Added memory statistics: free/shared/buffer/cached pages (sar -m).
2123 * Option -h added to sar to print its header periodically.
2124 * Set unavailable fields to zero when writing iostat file.
