1364 code. The bug may result in an assertion failure.
1365 * memcached plugin: Portability fix for Solaris. Thanks to Amit Gupta
1366 for reporting the bug.
1368 2009-06-02, Version 4.6.3
1369 * Build system, various plugins: Many build fixes for FreeBSD,
1370 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1371 for many fixes and providing a build system for many platforms,
1372 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1373 providing an OpenBSD system.
1374 * collectd: Two bugs with the threshold checking have been fixed. The
1375 first one prevented thresholds to be checked at all, the second one
1376 caused wrong behavior with the persistency option. Thanks to Andrés
1377 J. Díaz for fixing these problems.
1378 * collectd: Handling of the `Include' configuration option has been
1379 fixed.
1380 * battery plugin: Don't complain about a missing directory every
1381 interval.
1382 * exec plugin: Allow executed programs to close STDERR. Thanks to
1383 Thorsten von Eicken for reporting this problem.
1384 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1385 Tomasz Pala for the patch.
1386 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1387 the patch.
1388 * memory plugin: Fix a potential problem under Solaris.
1389 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1390 to Doug MacEachern for the patch.
1392 2009-03-18, Version 4.6.2
1393 * collectd: Some Solaris utility code has been improved.
1394 * filter subsystem: Allow `Chains' without default targets.
1395 * liboping: A patch to comply with strict aliasing rules has been
1396 added.
1397 * timediff match: Fix a typo: The match was registered with a wrong
1398 name which prevented this match to be used as documented. Thanks to
1399 Bruno Prémont for finding this problem.
1400 * bind plugin: Fix collection of the cached RR sets. The number of RR
1401 sets currently in the cache was collected as a counter value, which
1402 is nonsense. Thanks to Bruno Prémont for implementing this.
1403 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1404 primarily BSDs, don't take it well and crash.
1405 * oracle plugin: Portability to 64 bit systems has been improved.
1406 * postgresql plugin: The default configuration has been improved.
1407 * rrdtool plugin: Fix a possible race condition: If the network plugin
1408 is brought and dispatches a value before the rrdtool plugin is
1409 initialized, the daemon may crash.
1411 2009-02-22, Version 4.6.1
1412 * collectd: Many documentation fixes.
1413 * Collectd::Unixsock: Error handling has been improved.
1414 * regex match: Don't link with the PCRE library.
1415 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1416 for finding and fixing most of them.
1417 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1418 faults. Thanks to Peter Holik for his patch.
1420 2009-02-16, Version 4.6.0
1421 * collectd: Added the `filter chain' infrastructure, which allows the
1422 user to use `matches' and `targets' to control value processing.
1423 * collectd: The new `-T' command line argument allows more in-depth
1424 testing of a configuration. Thanks to Doug MacEachern for the patch.
1425 * collectd-nagios: The Nagios integration command has been updated to
1426 use libcollectdclient. The `percentage' aggregation function has
1427 been added. Thanks to Fabian Linzberger for the patch.
1428 * libcollectdclient: A library which abstracts communication with the
1429 unixsock plugin for clients has been added.
1430 * regex match: Match values by their identifies using regular
1431 expressions.
1432 * timediff match: Match for values with an invalid timestamp.
1433 * value match: Select values by their data sources' values.
1434 * notification target: Create and dispatch a notification.
1435 * replace target: Replace parts of an identifier using regular
1436 expressions.
1437 * set target: Set (overwrite) entire parts of an identifier.
1438 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1439 statistics, allowing very detailed name server statistics. Thanks to
1440 Bruno Prémont for this plugin.
1441 * cpu plugin: Report `interrupt' separately when using
1442 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1443 example for native OpenBSD support, has been added. Thanks to Simon
1444 Kuhnle for the patch.
1445 * csv plugin: Make it possible to write values to STDOUT instead of
1446 files. This is meant for testing purposes mostly. The output written
1447 to STDOUT is compatible with the exec plugin. Thanks to Doug
1448 MacEachern for the patch.
1449 * curl plugin: This new plugin can be used to read web pages and parse
1450 them using the same mechanism that's used in the tail plugin.
1451 * dbi plugin: This new plugin allows you to connect to a variety of
1452 relational databases and use SQL to gather custom statistics from
1453 it. It is similar to the already existing PostgreSQL plugin but uses
1454 libdbi to communicate with the database(s).
1455 * interface plugin: Use the ignorelist framework when selecting /
1456 ignoring interfaces. This allows one to use regular expressions to
1457 select interfaces, too.
1458 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1459 Thanks to Bruno Prémont for this patch.
1460 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1461 for the patch.
1462 * mysql plugin: Allow connecting to a database via the UNIX domain
1463 socket, too. Thanks to Mirko Buffoni for the patch.
1464 * network plugin: Further performance improvements for the receive
1465 code. This hopefully will help very large setups.
1466 * openvpn plugin: This new plugin collects statistics provided by the
1467 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1468 * oracle plugin: This new plugin allows you to connect to an Oracle
1469 database and use SQL to gather custom statistics from it. It is
1470 similar to the already existing PostgreSQL plugin.
1471 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1472 have been added.
1473 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1474 * perl plugin: Added support for `notification meta data'.
1475 * perl plugin: Added support for the `filter chain' infrastructure by
1476 allowing plugins to register `matches' and `targets'.
1477 * postgresql plugin: The preferred configuration syntax has been
1478 updated to be in line with the syntax used by the new dbi and oracle
1479 plugins. The compatibility code for the old syntax is present.
1480 Support for the new `Result' blocks and the interval parameter has
1481 been added.
1482 * processes plugin: Stacksize and virtual memory usage statistics have
1483 been added. Portability fixes.
1484 * rrdcached plugin: This new plugin uses the (still in development)
1485 RRD accelerator daemon, rrdcached. This daemon works very similar to
1486 the original rrdtool plugin of collectd, but adds some more nice
1487 features.
1488 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1489 added.
1491 2009-05-09, Version 4.5.4
1492 * Build system, various plugins: Many build fixes for FreeBSD,
1493 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1494 for many fixes and providing a build system for many platforms,
1495 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1496 providing an OpenBSD system.
1497 * collectd: Fix a potential race condition when creating directories.
1498 * battery plugin: Don't complain about a missing directory every
1499 interval.
1500 * dns plugin: Slight portability fixes.
1501 * exec plugin: Allow executed programs to close STDERR. Thanks to
1502 Thorsten von Eicken for reporting this problem.
1503 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1504 Tomasz Pala for the patch.
1505 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1506 the patch.
1507 * rrdtool plugin: Fix a possible race condition: If the network plugin
1508 is initialized and dispatches a value before the rrdtool plugin is
1509 initialized, the daemon may crash.
1510 * memory plugin: Fix a potential problem under Solaris.
1512 2009-02-22, Version 4.5.3
1513 * build system: The check for libupsclient even when `pkg-config' is
1514 not available.
1515 * collectd: Fix error handling in the global cache.
1516 * Collectd::Unixsock: Error handling has been improved.
1517 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1518 patch.
1519 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1520 faults. Thanks to Peter Holik for his patch.
1521 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1522 code. Thanks to "thated" for reporting this.
1524 2009-01-02, Version 4.5.2
1525 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1526 file may be in both locations, especially when the database was
1527 installed in a non-standard path. Thanks to Dusty Doris for
1528 reporting this.
1529 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1530 Solaris, in the configure script automatically.
1531 * build system, tcpconns plugin: Check for `kvm_nlist' and
1532 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1533 library with similar functions to the BSD variant, but doesn't
1534 provide these necessary functions.
1535 * collectd.conf(5): Various fixes and clarifications.
1536 * collectd: Remove a GNUism (unnamed unions), thus improving
1537 portability.
1538 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1539 This solves portability problems, especially for Solaris.
1540 * dns plugin: Fix a portability problem with NetBSD.
1541 * filecount plugin: Fix an off-by-one error. This error may cause a
1542 segmentation fault.
1543 * network plugin: Fix the handling of `type' in the network protocol.
1544 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1545 much larger buffer. This caused the `type' to be transferred much
1546 more often than necessary. In some cases, e. g. the `cpu' and
1547 `cpufreq' plugins being used at the same time, data may be corrupted
1548 in those files. Thanks to Bruno Prémont for debugging and reporting
1549 this issue.
1550 * processes plugin: Fix a possible segmentation fault when specifying
1551 invalid configuration options.
1552 * unixsock plugin: Make sure the initialization function is run only
1553 once. This resolves a file descriptor leak under systems which run
1554 the initialization more than once, such as Solaris.
1556 2008-10-16, Version 4.5.1
1557 * build system: Change `--enable-<plugin>' to abort with an error if
1558 dependencies are not met. Thanks to Bruno Prémont for the patch.
1559 Also, the poisoning of various string functions has been restricted
1560 to debug builds.
1561 * collectd: Fix a memory leak in the global value cache. With every
1562 *missing* value a couple of bytes would be leaked. Another memory
1563 leak in the configuration handling code has been fixed. Thanks to
1564 Niraj Tolia for reporting these issues.
1565 * collectd: Fix an off-by-one error in the ignorelist functionality.
1566 When using regular expressions, the last character would be missing,
1567 possibly matching differently from what one would expect.
1568 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1569 problem.
1570 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1571 Linzberger for reporting the bug.
1572 * iptables plugin: Fix an off-by-one error. If a string was just one
1573 character too long, it was truncated instead of reporting an error.
1574 * network plugin: Fix a memory leak in the configuration handling
1575 code. Thanks to Niraj Tolia for reporting this issue.
1576 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1577 * postgresql plugin: Don't reopen connection during reinitialization.
1578 This fixes a bug under Solaris and potentially other platforms.
1579 Missing calls to `PQclear' have been added, too. This fixes memory
1580 leaks. Thanks to ``Admin'' for reporting these bugs.
1581 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1582 library.
1583 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1584 problems with some `libc's. Thanks to Matthias Lay for reporting the
1585 bug.
1587 2008-09-04, Version 4.5.0
1588 * collectd: Added the ability to flush certain identifiers.
1589 * collectd: The concept of `notification meta data' has been
1590 introduced.
1591 * filecount plugin: The new filecount plugin counts the number of
1592 files in a directory and its subdirectories.
1593 * ipmi plugin: Sensor names have been changed to ensure unique names.
1594 Notifications upon added and removed sensors can now be generated.
1595 * notify_desktop plugin: This new plugin sends notifications to the
1596 X desktop using the structure defined in the `Desktop Notification
1597 Specification'.
1598 * notify_email plugin: This new plugin sends out notifications via
1599 email, using the `esmtp' library.
1600 * onewire plugin: The new experimental(!) onewire plugin reads values,
1601 such as temperatures, from sensors connected to the computer via the
1602 onewire bus.
1603 * perl plugin: Improved synchronized access to internal data structures
1604 and fixed a possible dead-lock.
1605 * perl plugin: Added the ability to flush certain identifiers and marked
1606 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1607 plugin_flush().
1608 * perl plugin: Added the ability to configure Perl plugins.
1609 * postgresql plugin: The new postgresql plugin collects statistics
1610 about or from a PostgreSQL database.
1611 * processes plugin: The `ProcessMatch' option has been added.
1612 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1613 IO load.
1614 * tcpconns plugin: This plugin has been ported to OpenBSD.
1615 * thermal plugin: The new thermal plugin collects system temperatures
1616 using Linux ACPI thermal zone data.
1618 2009-01-02, Version 4.4.5
1619 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1620 file may be in both locations, especially when the database was
1621 installed in a non-standard path. Thanks to Dusty Doris for
1622 reporting this.
1623 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1624 Solaris, in the configure script automatically.
1625 * collectd.conf(5): Various fixes and clarifications.
1626 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1627 portability problems, especially for Solaris.
1628 * dns plugin: Fix a portability problem with NetBSD.
1629 * network plugin: Fix the handling of `type' in the network protocol.
1630 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1631 much larger buffer. This caused the `type' to be transferred much
1632 more often than necessary. In some cases, e. g. the `cpu' and
1633 `cpufreq' plugins being used at the same time, data may be corrupted
1634 in those files. Thanks to Bruno Prémont for debugging and reporting
1635 this issue.
1636 * unixsock plugin: Make sure the initialization function is run only
1637 once. This resolves a file descriptor leak under systems which run
1638 the initialization more than once, such as Solaris.
1640 2008-10-16, Version 4.4.4
1641 * build system: Change `--enable-<plugin>' to abort with an error if
1642 dependencies are not met. Thanks to Bruno Prémont for the patch.
1643 Also, the poisoning of various string functions has been restricted
1644 to debug builds.
1645 * collectd: Fix a memory leak in the global value cache. With every
1646 *missing* value a couple of bytes would be leaked. Another memory
1647 leak in the configuration handling code has been fixed. Thanks to
1648 Niraj Tolia for reporting these issues.
1649 * collectd: Fix an off-by-one error in the ignorelist functionality.
1650 When using regular expressions, the last character would be missing,
1651 possibly matching differently from what one would expect.
1652 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1653 problem.
1654 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1655 Linzberger for reporting the bug.
1656 * network plugin: Fix a memory leak in the configuration handling
1657 code. Thanks to Niraj Tolia for reporting this issue.
1658 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1659 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1660 problems with some `libc's. Thanks to Matthias Lay for reporting the
1661 bug.

1672 * collectd: Try even harder to determine the endianess of the
1673 architecture collectd is being built on.
1674 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1675 of disks.
1676 * dns plugin: Fix compilation errors with BIND versions 19991001
1677 through 19991005.
1678 * network plugin: Bugfix in the init routine: The init function
1679 cleared a buffer regardless of its contents. This could lead to lost
1680 values under Solaris.
1681 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1682 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1683 function.
1684 * wireless plugin: Work around incorrect noise and power values
1685 returned by some broken drivers.
1687 2008-06-03, Version 4.4.1
1688 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1689 to kyrone for reporting this.
1690 * collectd: Fixed min/max output in notifications generated by
1691 threshold checking.
1692 * collectd-nagios: Fix the protocol used to communicate with the
1693 daemon.
1694 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1695 initialization has errors. An issue with Perl 5.10 has been fixed.
1696 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1697 René Rebe and Siegmund Gorr for reporting this.
1699 2008-05-06, Version 4.4.0
1700 * collectd: Internal code cleanups.
1701 * collectd: Added support for a `Flush' command in the unixsock and
1702 exec plugins. This command can be used to force a plugin (or all) to
1703 flush its values to disk.
1704 * collectd: Thresholds can now be configured to apply to one data
1705 source only, making it possible to configure different thresholds
1706 for each data source.
1707 * apache, nginx plugins: Added the possibility to disable host and/or
1708 peer verification.
1709 * ascent plugin: The new ascent plugin reads and parses the statistics
1710 page of an Ascent server.

1716 sensor values via IPMI, the intelligent platform management
1717 interface.
1718 * iptables plugin: The iptc library that is used by the iptables
1719 plugin has been added to the distribution, because it is not
1720 provided by all distributions and removed from at least one.
1721 * powerdns plugin: The new powerdns plugin reads statistics from an
1722 authoritative or a recursing PowerDNS name server.
1723 * rrdtool plugin: The size of the files generated with the default
1724 configuration has been decreased.

1754 they are in non-standard paths.
1755 * build system: Portability fixes: Automatically define "_REENTRANT"
1756 if the libc expects it.
1757 * collectd: Error and warning messages have been improved.
1758 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1759 using them.

1777 * exec plugin: Set supplementary group IDs.
1778 * network plugin:
1779 + Use `memcpy' when constructing/parsing a package to avoid
1780 alignment problems on weird architectures, such as Sparc.
1781 + Translate doubles to/from the x86 byte representation to ensure
1782 cross-platform compatibility.
1783 * ping plugin: Correct the handling of the `TTL' setting.
1784 * swap plugin: Reapply a patch for Solaris.
1785 * tcpconns plugin: Portability improvements.
1787 2008-02-18, Version 4.3.0
1788 * collectd: Notifications have been added to the daemon. Notifications
1789 are status messages that may be associated with a data instance.
1790 * collectd: Threshold checking has been added to the daemon. This
1791 means that you can configure threshold values for each data
1792 instance. If this threshold is exceeded a notification will be
1793 created.
1794 * collectd: The new `FQDNLookup' option tells the daemon to use the
1795 full qualified domain name as the hostname, not just the host part
1796 es returned by `gethostname(2)'.
1797 * collectd: Support for more than one `TypesDB' file has been added.
1798 This is useful when one such file is included in a package but one
1799 wants to add custom type definitions.
1800 * collectd: The `Include' config option has been expanded to handle
1801 entire directories and shell wildcards.
1802 * collectdmon: The new `collectdmon' binary detects when collectd
1803 terminates and automatically restarts it again.
1804 * csv plugin: The CSV plugin is now able to store counter values as a
1805 rate, using the `StoreRates' configuration option.
1806 * exec plugin: Handling of notifications has been added and the

1808 * hddtemp plugin: The new `TranslateDevicename' option lets you
1809 disable the translation from device names to major-minor-numbers.
1810 * logfile plugin: Handling of notifications has been added.
1811 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1812 domain name lookups in this plugin.
1813 * perl plugin: Many internal changes added support for handling multiple
1814 threads making the plugin reasonably usable inside collectd. The API has
1815 been extended to support notifications and export global variables to
1816 Perl plugins; callbacks now have to be identified by name rather than a
1817 pointer to a subroutine. The plugin is no longer experimental.
1818 * uuid plugin: The new UUID plugin sets the hostname to an unique
1819 identifier for this host. This is meant for setups where each client
1820 may migrate to another physical host, possibly going through one or
1821 more name changes in the process. Thanks to Richard Jones from
1822 Red Hat's Emerging Technology group for this plugin.
1823 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1824 CPU, disk and network statistics about guest systems on the same
1825 physical server. Thanks to Richard Jones from Red Hat's Emerging
1826 Technology group for this plugin.
1828 2008-04-22, Version 4.2.7
1829 * build system: Improved detection of several libraries, especially if
1830 they are in non-standard paths.
1831 * build system: Portability fixes: Automatically define "_REENTRANT"
1832 if the libc expects it.
1833 * collectd: Error and warning messages have been improved.
1834 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1835 using them.
1836 * apache plugin: Allocate new memory when reading a webpage instead of
1837 using a buffer of static size.
1838 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1839 the program.
1840 * hddtemp plugin: Error and warning messages have been improved.
1841 * sensors plugin: Fix sensor collection for some chip types.
1843 2008-03-29, Version 4.2.6
1844 * collectd: Improved error messages when parsing the configuration.
1845 * sensors plugin: Fix temperature collection with libsensors4.
1846 * unixsock plugin: Fix mixed input and output operation on streams.
1847 * wireless plugin: Fix reading noise value.
1849 2008-03-04, Version 4.2.5
1850 * apache plugin: Improved initialization and error messages.
1851 * exec plugin: Set supplementary group IDs.
1852 * network plugin:
1853 + Create separate threads for reading from the socket and parsing
1854 and dispatching incoming packets. Versions prior to this may have
1855 problems in high-load situations, where the socket receive buffers
1856 overflows, resulting in gaps in the data.
1857 + Use `memcpy' when constructing/parsing a package to avoid
1858 alignment problems on weird architectures, such as Sparc.
1859 + Translate doubles to/from the x86 byte representation to ensure
1860 cross-platform compatibility.
1861 * ping plugin: Correct the handling of the `TTL' setting.
1862 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1863 * swap plugin: Reapply a patch for Solaris.
1864 * tcpconns plugin: Portability improvements.
1866 2008-01-21, Version 4.2.4
1867 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1868 the permission on the socket as documented in the manpage. Thanks to
1869 Evgeny Chukreev for fixing this issue.
1870 * collectd: The documentation has been improved.
1872 2007-12-28, Version 4.2.3
1873 * sensors plugin: Updated the plugin to build and work with version 3
1874 of the libsensors library.
1876 2007-12-15, Version 4.2.2
1877 * nginx plugin: Incorrect comparison of strings lead to a segfault
1878 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1879 this.
1880 * logfile plugin: The config option `Timestamp' was handled
1881 incorrectly and basically always active. Thanks to Luke Heberling
1882 for fixing this.
1884 2007-11-08, Version 4.2.1
1885 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1886 enabled on the host.
1887 * snmp plugin: Fix a memory leak.
1889 2007-10-27, Version 4.2.0
1890 * collectd: The new config option `Include' lets you include other
1891 configfiles and thus split up your config into smaller parts. This
1892 may be especially interesting for the snmp plugin to keep the data
1893 definitions separate from the host definitions.
1894 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1895 (number of connections, octets and packets for each service and
1896 destination). Thanks to Sebastian Harl for this plugin.
1897 * memcached plugin: The new `memcached' plugin connects to a memcached
1898 daemon process and collects statistics of this distributed caching
1899 system. Thanks to Antony Dovgal for contributing this plugin.
1900 * nginx plugin: The new `nginx' plugin reads the status page of an
1901 nginx daemon and saves the handled connections and requests.
1902 * perl plugin: Many changes, including the added `EnableDebugger'
1903 config option which lets you debug your Perl plugins more easily.
1904 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1905 be more thread-safe otherwise by locking calls to the library.
1906 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1907 correct the values returned by SNMP-agents. If a <data> block is
1908 defined as `table' the instance is now optional. The sequence number
1909 is used as the type-instance in this case. The new `InstancePrefix'
1910 option allows to add arbitrary prefixes to the type-instance.
1911 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1912 certain TCP connections and what state they're in. This can be used
1913 to see how many connections your FTP server has to handle or how
1914 many outgoing connections your mailserver has open.
1916 2008-01-11, Version 4.1.6
1917 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1918 the permission on the socket as documented in the manpage. Thanks to
1919 Evgeny Chukreev for fixing this issue.
1920 * collectd: The documentation has been improved.
1922 2007-12-27, Version 4.1.5
1923 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1924 memory situations.
1925 * sensors plugin: Updated the plugin to build and work with version 3
1926 of the libsensors library.
1928 2007-11-08, Version 4.1.4
1929 * Build system: Improve detection of the rrd library, especially if
1930 it's in a non-standard location.
1931 * Build system: A bug when parsing the argument for
1932 `--with-libnetsnmp' has been fixed.
1933 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1934 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1935 a deadlock or delay when shutting down the daemon.
1936 * snmp plugin: Fix a memory leak.
1938 2007-10-24, Version 4.1.3
1939 * collectd: A build issue under Solaris has been resolved by renaming
1940 data types.
1941 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1942 be more thread-safe otherwise by locking calls to the library.
1944 2007-09-28, Version 4.1.2
1945 * apcups plugin: Fix reporting of the `load percent' data.
1946 * wireless plugin: Correct the handling of cards returning signal and
1947 noise quality as percentage.
1948 * perl plugin: Fix a possible buffer overflow in get_module_name().
1949 * build system: Further improve the detection of libraries.
1950 * netlink plugin: Build issues under some older versions of the Linux
1951 includes (i. e. Debian Sarge) have been fixed.
1952 * snmp plugin: Fix a potential segfault when a host times out. Add
1953 support for the `timeticks' type.
1955 2007-09-12, Version 4.1.1
1956 * Build system: The detection of `libnetlink' has been improved.
1957 * collectd: The documentation has been fixed in numerous places.
1958 * exec plugin: Setting the group under which to run a program has been
1959 fixed.
1960 * collectd: The `sstrerror' function was improved to work correctly
1961 with the broken GNU version of `strerror_r'.
1962 * collectd: Write an error message to STDERR when loading of a plugin
1963 fails.
1964 * apcups plugin: Fix the `types' used to submit the values: They still
1965 has an `apcups_' prefix which doesn't work anymore.
1966 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1967 whatever the client thinks is `now'..
1969 2007-09-01, Version 4.1.0
1970 * Build system: The build system has been changed to automatically
1971 disable all plugins, which are missing dependencies. The dependency
1972 checking has been removed from the plugins themselves to remove
1973 redundancy.
1974 * Flexible interval: The interval of collected data is now sent along
1975 with the data itself over the network, so that the interval-settings
1976 of server and clients no longer needs to match.
1977 * netlink plugin: The new `netlink' plugin connects to the Linux
1978 kernel using a netlink socket and uses it to query information about
1979 interfaces, qdiscs and classes.
1980 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1981 to not block data collection.
1982 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1983 network devices, such as switches, routers, thermometers, rack
1984 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1985 plugin.
1986 * unixsock plugin: Added the `LISTVAL' command.
1987 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1988 of music played with xmms.
1990 2007-09-28, Version 4.0.9
1991 * apcups plugin: Fix reporting of the `load percent' data.
1992 * wireless plugin: Correct the handling of cards returning signal and
1993 noise quality as percentage.
1994 * perl plugin: Fix a possible buffer overflow in get_module_name().
1996 2007-09-12, Version 4.0.8
1997 * collectd: The `sstrerror' function was improved to work correctly
1998 with the broken GNU version of `strerror_r'.
1999 * collectd: Write an error message to STDERR when loading of a plugin
2000 fails.
2001 * apcups plugin: Fix the `types' used to submit the values: They still
2002 has an `apcups_' prefix which doesn't work anymore.
2003 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2004 whatever the client thinks is `now'..
2006 2007-08-26, Version 4.0.7
2007 * documentation: Some typos have been fixed and some information has
2008 been improved.
2009 * build system: Many fixes for detecting libraries in unusual places,
2010 such as on RedHat systems. The affected libraries are `libcurl',
2011 `libmysql', and `libupsclient'.
2012 * network plugin: Allow the `Port' option to be specified as a number
2013 (i. e. without quotes).
2014 * nut plugin: A fix allows linking the nut plugin against
2015 libupsclient, version >= 2.2.0.
2016 * processes plugin: Fix a potential segmentation fault.
2018 2007-07-30, Version 4.0.6
2019 * sensors plugin: Fix the ignorelist functionality: Only the `type
2020 instance' was used to match against the list, but the documentation
2021 told otherwise. This release fixes the code, so it complies with the
2022 documentation.
2023 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2024 configuration messages will end up in the logging facility.
2025 * conrtib/fedora: The contributed specfile for Fedora has been
2026 updated.
2028 2007-07-05, Version 4.0.5
2029 * Portability: More fixes for OpenBSD have been included.
2031 2007-06-24, Version 4.0.4
2032 * cpu plugin: Fixed the Solaris code.
2033 * dns plugin: Fixed a build issue for OpenBSD.
2034 * interface plugin: Fixed the Solaris code.
2035 * load plugin: Fixed the alternative `/proc' Linux code.
2036 * memory plugin: Fixed the Solaris code.
2037 * oconfig: Don't require `-lfl' anymore.
2039 2007-06-19, Version 4.0.3
2040 * cpu plugin: Fix the Darwin / Mac OS X code.
2041 * ping plugin: Use the return value of `getpid', not its address.
2042 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2043 initialized correctly.
2044 * configure: Added `--with-nan-emulation' to aid cross compilation.
2046 2007-06-12, Version 4.0.2
2047 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2048 they're given in numerically form.
2050 2007-06-07, Version 4.0.1
2051 * iptables plugin: A bug in the configuration routine has been fixed.
2052 Setting a comment in the configfile will no longer cause a
2053 segmentation fault.
2055 2007-06-03, Version 4.0.0
2056 * collectd: The plugin-infrastructure has been changed to allow for
2057 more types of plugins, namely `write' and `log' plugins.
2058 * collectd: The read-function has been changed to read many plugins in
2059 parallel, using threads. Thus, plugins generally need to use
2060 thread-safe functions from now on.
2061 * collectd: The '-t' command line options allows to perform syntax tests
2062 of the configuration file and exit immediately.
2063 * csv plugin: The new `csv' plugin handles output to `comma separated
2064 values'-files.
2065 * rrdtool plugin: The new `rrdtool' plugin handles output to
2066 RRD-files. Data can be cached to combine multiple updates into one
2067 write to increase IO-performance.
2068 * network plugin: The new `network' plugin handles IO via the network.
2069 It implements a different, much more extensible protocol which can
2070 combine many values in one packet, decreasing the number of UDP-
2071 packets being sent. It can read from and send to the network and
2072 with the appropriate configuration even forward packets to other
2073 networks.
2074 * unixsock plugin: The new `unixsock' plugin provides an interface to
2075 communicate with the daemon while it is running. Right now the
2076 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2077 come.
2078 * perl plugin: The new `perl' plugin allows you to write extensions
2079 for collectd in the scripting-language Perl.
2080 * logfile plugin: The new `logfile' plugin writes logmessages to files
2081 or STDOUT or STDERR.
2082 * syslog plugin: The new `syslog' plugin sends logmessages to the
2083 system's syslog daemon.
2084 * entropy plugin: The new `entropy' plugin collects the amount of
2085 entropy currently being available to the system.
2086 * exec plugin: The new `exec' plugin forks child processes and reads
2087 back values provided by the forked processes.
2088 * iptables plugin: The new `iptables' plugin reads counters from
2089 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2090 plugin.
2091 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2092 to Peter Holik for contributing this plugin.
2093 * nut plugin: The new `nut' plugin connects the upsd of the `network
2094 ups tools' and reads information about the connected UPS.
2095 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2096 connections) field was added by Florent Monbillard.
2097 * collectd-nagios: The new `collectd-nagios' binary queries values
2098 from collectd, parses them and exits according to Nagios-standards.
2099 * manpages: The manpages have been improved a lot.
2101 2007-09-28, Version 3.11.7
2102 * wireless plugin: Correct the handling of cards returning signal and
2103 noise quality as percentage.
2105 2007-08-31, Version 3.11.6
2106 * processes plugin: Fix a potential segmentation fault.
2108 2007-05-29, Version 3.11.5
2109 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2110 * ntpd plugin: Fix a potential buffer overflow.
2111 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2112 were accounted as `zombies'.
2114 2007-04-10, Version 3.11.4
2115 * dns plugin: Change the order of includes to make the plugin compile
2116 under FreeBSD.
2118 2007-03-30, Version 3.11.3
2119 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2120 of the unused `COLLECT_KSTAT'.
2122 2007-02-11, Version 3.11.2
2123 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2124 NULL-pointer may have been passed to `printf' which causes a
2125 segfault with some libcs.
2127 2007-02-10, Version 3.11.1
2128 * df plugin: Some wrong defines have been fixed so the plugin works
2129 under Solaris again.
2130 * dns plugin: The usage of a struct has been fixed to work with
2131 non-GNU libcs.
2132 * processes plugin: Some missing defines have been added so the plugin
2133 compiles cleanly under FreeBSD and presumably other UNIXes.
2135 2006-12-22, Version 3.11.0
2136 * collectd: The new command line option `-P' makes it easier for
2137 distributors to change the location of PID-files.
2138 * collectd: The daemon shuts down faster now which makes it easier to
2139 write init.d-scripts for it.
2140 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2141 caused problems every now and then.
2142 * df plugin: New config options allow to ignore certain mountpoints,
2143 filesystem types or devices.
2144 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2145 and interprets it. It collects traffic as well as qtype, opcode and
2146 rcode counts.
2147 * email plugin: Sebastian Harl has contributed this plugin which
2148 counts received mails in categories (e. g. ham, spam, virus), spam
2149 score (as given by SpamAssassin) and check types.
2150 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2151 uses `mbmon' to gather information from sensors on the motherboard.
2152 * processes plugin: Collect detailed statistics for configured
2153 processes, that's process and thread count, CPU usage, resident
2154 segment size and pagefaults.
2155 * multimeter plugin: Peter Holik contributed a new plugin which
2156 queries multimeters.
2157 * sensors plugin: Lubos Stanek has put much effort into improving this
2158 plugin, including `extended naming', collection of voltage values
2159 and the possibility to ignore certain values.
2161 2006-12-21, Version 3.10.4
2162 * Max Kellermann has identified a bug in the server routine: When
2163 opening a socket fails the daemon will (re)try opening the socket in
2164 an endless loop, ultimately leading to a `EMFILE' error.
2166 2006-11-04, Version 3.10.3
2167 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2168 ntpd's reply was sent in more than one packet, the buffer size was
2169 calculated incorrectly, resulting in the reading of uninitialized or
2170 freed memory.
2172 2006-11-01, Version 3.10.2
2173 * The sample config file has been improved.
2174 * Errors in the manpages have been corrected.
2175 * The ping-plugin now adds hosts during initialization, not during
2176 startup. This speeds up startup when no network connectivity is
2177 available. Also, the hosts are being added later when the network is
2178 available.
2179 * Improved BSD-support for the df-plugin.
2180 * Fixed syntax errors in the swap-plugin for Mac OS X.
2181 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2182 plugin.
2183 * Don't disable the mysql-plugin if connecting to the database fails
2184 during initialization. Instead, try again in increasing intervals.
2186 2006-07-19, Version 3.10.1
2187 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2188 the apcups cannot be reached, unconnected sockets will pile up and
2189 eventually lead to `Too many open files' errors.
2191 2006-07-09, Version 3.10.0
2192 * The `disk' plugin has been ported to Darwin.
2193 * The `battery' plugin should work on many Apple computers now.
2194 * The `traffic' plugin can now ignore certain interfaces. Also,
2195 statistics for sent/received packets and errors have been added.
2196 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2197 to Anthony Gialluca for contributing this plugin and providing me
2198 with a test environment :)
2199 * A plugin for monitoring an NTP instance and the local clock drift
2200 has been added.
2202 2006-06-25, Version 3.9.4
2203 * The Solaris code in the `swap' plugin has been changed to reflect
2204 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2205 working this out.
2206 * The debugging system has been fixed to work with the Sun libc.
2207 * When built without librrd the variable `operating_mode' could be
2208 uninitialized. Thanks to David Elliot for reporting the bug.
2210 2006-06-01, Version 3.9.3
2211 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2212 operating systems also profit from the changes, but I wasn't able to
2213 check that.
2214 * Changed the build system to find the netinet-includes under FreeBSD
2215 and therefore successfully build the `liboping' library there.
2217 2006-05-09, Version 3.9.2
2218 * Applied a patch to the `liboping' library. Due to a bug in the
2219 sequence checking the `ping' plugin stopped working after
2220 approximately 7.6 days.
2222 2006-05-09, Version 3.8.5
2223 * Applied a patch to the `liboping' library. Due to a bug in the
2224 sequence checking the `ping' plugin stopped working after
2225 approximately 7.6 days.
2227 2006-04-21, Version 3.9.1
2228 * Build issues with Solaris and possible other architectures have been
2229 resolved.
2230 * Problems when building the `apache'-plugin without `libcurl' have
2231 been resolved.
2232 * A bug in the `ping' plugin has been fixed. Sorry folks.
2234 2006-04-02, Version 3.9.0
2235 * A plugin to monitor the Apache webserver has been added.
2236 <http://httpd.apache.org/>
2237 * A plugin to collect statistics about virtual servers using VServer.
2238 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2239 this plugin :)
2240 * A plugin for wireless LAN cards has been added. It monitors signal
2241 strength, link quality and noise ratio..
2242 * A plugin for Apple hardware sensors has been added.
2243 * An option to compile collectd with different `step' and `heartbeat'
2244 settings has been added. The size of RRAs is no longer static but
2245 calculated based on the settings for `step' and `width'.
2246 * The `ping' plugin can now be configured to use a certain TTL.
2247 * A plugin to monitor the hardware sensors of Apple computers has been
2248 added.
2249 * The plugins `cpu', `memory', `processes' and `traffic' have been
2250 ported to Mach/Darwin (Mac OS X).
2251 * The `log mode' has been contributed by Christophe Kalt. It writes
2252 the data into text files rather than RRD files.
2254 2006-04-09, Version 3.8.4
2255 * Applied patch by Vincent Stehlé which improves the disk-name
2256 resolution in the `hddtemp' plugin for Linux systems.
2258 2006-04-02, Version 3.8.3
2259 * Applied a patch by James Byers: The MySQL plugin was not working
2260 with MySQL 5.0.2 or later.
2262 2006-03-14, Version 3.8.2
2263 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2264 the GNU libc, because it points to `/etc/fstab' rather than
2265 `/etc/mtab'.
2267 2006-03-13, Version 3.8.1
2268 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2269 * Fixes in the debian `postinst' and `init.d' scripts.
2271 2006-03-09, Version 3.8.0
2272 * The `ping' plugin no longer uses `libping' but a self written
2273 library named `liboping'. With this library it's possible to ping
2274 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2276 2006-02-18, Version 3.7.2
2277 * A simple bug in the `battery' plugin has been fixed. It should now
2278 work with ACPI based batteries as well. Thanks to Sebastian for
2279 fixing this.
2280 * Fixing a bug that prevented collectd to be built without librrd.
2281 Thanks to Werner Heuser for reporting it.
2283 2006-02-04, Version 3.7.1
2284 * The new network code has been improved to build with older versions
2285 of glibc.
2286 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2287 to Tommie Gannert for this patch.
2289 2006-01-30, Version 3.7.0
2290 * The `battery' plugin has been added. It collects information about
2291 laptop batteries..
2292 * The MySQL plugin has been improved: It now writes two more RRD
2293 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2294 * The `cpufreq' plugin now reads another file since the file it did
2295 read so far causes much overhead in the kernel. Also, you need root
2296 to read the old file, but not to read the new one.
2297 * The `hddtemp' plugin can now be configured to connect to another
2298 address and/or port than localhost.
2299 * The `df' plugin now prefers `statvfs' over `statfs'.
2300 * The network code has been rewritten. collectd now supports unicast
2301 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2302 be set in the configfile.
2304 2006-01-24, Version 3.6.2
2305 * Due to a bug in the configfile handling collectd wouldn't start in
2306 client mode. This released fixes this.
2308 2006-01-20, Version 3.6.1
2309 * Due to a bug in `configure.in' all modules and the binary were
2310 linked against `libmysqlclient'. This issue is solved by this
2311 release.
2313 2006-01-17, Version 3.6.0
2314 * A config file has been added. This allows for loading only specific
2315 plugins.
2316 * A `df' plugin has been added.
2317 * A `mysql' plugin has been added.
2318 * The `ping' plugin doesn't entirely give up hope when a socket error
2319 occurred, but will back of and increase the intervals between tries.
2321 2006-01-21, Version 3.5.2
2322 * Fixed yet another bug in the signal handling.. Stupid typo..
2323 * Improved the ping plugin to not give up on socket errors (backport
2324 from 3.6.0).
2326 2005-12-18, Version 3.5.1
2327 * The PID-file is now deleted correctly when shutting down the daemon.
2328 * SIGINT and SIGTERM are now handled correctly.
2330 2005-12-16, Version 3.5.0 (Revision 326)
2331 * A bug in the `load' module under Solaris has been fixed.
2332 * The `users' module has been contributed by Sebastian Harl. It counts
2333 currently logged in users.
2334 * The CPU module now works under FreeBSD without the use of
2335 `libstatgrab', however SMP support is missing.
2336 * The default directories for the RRD files and the PID file now
2337 depend on the compile time setting of `localstatedir'.
2339 2005-11-15, Version 3.4.0 (Revision 236)
2340 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2341 from gentoo's bugzilla for writing the patch.
2342 * The build dependency for librrd has been removed. Binaries built
2343 without librrd are client-only and will multicast their value as
2344 with the `-c' argument.
2345 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2346 * The newly introduced `-f' switch prevents daemon initialization
2347 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2348 Barcellos for this patch.
2350 2005-11-04, Version 3.3.0 (Revision 216)
2351 * New modules have been added:
2352 - `serial', for monitoring traffic on the serial interfaces
2353 - `nfs', for graphing NFS procedure calls
2354 - `tape', traffic from/to tape devices
2355 * The memory.rrd now accepts more than 4Gig of memory.
2357 2005-10-26, Version 3.2.0 (Revision 200)
2358 * Support for graphing the processes has been added (thanks to Lyonel
2359 Vincent)
2360 * If reading from hddtemp fails collectd will increase the time
2361 between polls up to one day.
2362 * The init.d files have been improved.
2363 * Problems with the spec file have been fixed.
2365 2005-10-16, Version 3.1.0 (Revision 194)
2366 * Added the `setsid' syscall to the startup code.
2367 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2369 2005-09-30, Version 3.0.0 (Revision 184)
2370 * The ability to send/receive data to/from the network (think
2371 multicast) has been added.
2372 * Modules have been split up into shared libraries can be loaded at
2373 runtime. The biggest advantage is that the core program doesn't need
2374 to be linked against an external library.
2375 * A patch by George Kargiotakis has been applied: It fixes the sensors
2376 behaviour then more than one sensor is being queried.
2378 2005-09-16, Version 2.1.0 (Revision 172)
2379 * A module for swap statistics has been added.
2381 2005-09-09, Version 2.0.0 (Revision 135)
2382 * Filenames can no longer be configured at program startup. The only
2383 options as of this version are the directory and ping hosts.
2384 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2385 Soft-IRQ statistics are added to `System'.
2386 * Diskstats now collect read and write bytes, not sectors.
2387 * Ping statistics can now be collected for more than one host. There
2388 is no default any more: If no host is given no host will be pinged.
2389 * A self-written patch for libping has been applied so it builds
2390 cleanly.
2392 2005-09-01, Version 1.8.1 (Revision 123)
2393 * Much improved configure-script: libraries and features may now be
2394 disabled.
2395 * More detailed warnings/error messages when RRD update fails.
2397 2005-08-29, Version 1.8.0:
2398 * Support for collecting disk statistics under Solaris.
2400 2005-08-25, Version 1.7.0:
2401 * Support for libstatgrab[1] for load, memory usage and network
2402 traffic. CPU- and disk-usage are not (yet) supported, since
2403 libstatgrab returns insufficient information. I will contact the
2404 authors.
2405 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2406 aren't necessarily counted linear which is now handled correctly.
2407 [1]: http://www.i-scream.org/libstatgrab/
2409 2005-08-21, Version 1.6.0:
2410 * Basic support for Solaris: System load and cpu-usage can be
2411 collected under Solaris, too. Other stats will follow later.
2412 * Many fixes in the autoconf-script
2413 * Collection/Museum scripts have been added under contrib/museum
2414 * collectd may now be started in unprivileged mode, though ping
2415 statistics will not work.
2417 2005-07-17, Version 1.5.1:
2418 * Diskstats-RRDs now use major/minor for naming. Some systems have
2419 weird strings as disk-names..
2421 2005-07-17, Version 1.5:
2422 * A new module, diskstats, has been added. It collects information
2423 about the disks and partitions.
2425 2005-07-11, Version 1.4.2:
2426 * The meminfo module has been changed to work with more platforms
2427 and/or kernel versions.
2429 2005-07-10, Version 1.4.1: Correct traffic stats
2430 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2431 forgot to correct when I changed that module.
2433 2005-07-09, Version 1.4: More traffic stats
2434 * Traffic is now collected for all interfaces that can be found
2435 * Temperature-statistics are read from lm-sensors if available
2437 2005-07-08, Version 1.3: CPU stats
2438 * Collecting CPU statistics now
2440 2005-07-12, Version 1.2: Using syslog
2441 * collectd is now using the syslog facility to report errors, warnings
2442 and the like..
2443 * The default directory is now /var/db/collectd
2445 2005-07-10, Version 1.1: Minor changes
2446 * Nothing really useful to say ;)
2448 2005-07-09, Version 1.0: Initial Version
2449 * The following modules are provided:
2450 * Load average
2451 * Ping time
2452 * Traffic
2453 * Memory info
