1358 caused wrong behavior with the persistency option. Thanks to Andrés
1359 J. Díaz for fixing these problems.
1360 * collectd: Handling of the `Include' configuration option has been
1361 fixed.
1362 * rrdtool plugin: Make sure initialization is run only once. This
1363 resolves problems under Solaris and potentially other systems.
1364 Thanks to Amit Gupta for reporting this bug.
1365 * java plugin: Make it possible to use dots ('.') instead of slashes
1366 ('/') as the class separator. Thanks to Randy Rizun for pointing
1367 this out.
1368 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1369 to Doug MacEachern for the patch.

1382 multicast traffic from Ganglia's gmond daemon.
1383 * java plugin: The new java plugin exports the collectd API to Java,
1384 making it possible to write extensions to collectd in Java.
1385 * memcachec plugin: The new memcachec plugin queries data from a
1386 memcached daemon and parses it similar to the cURL plugin. Thanks to
1387 Doug MacEachern for the initial code.
1388 * memcached plugin: Support for connections over UNIX domain sockets
1389 has been added. Thanks to Franck Lombardi for the patch.

1402 plugin must no longer be a multiple of the global interval.
1403 * table plugin: The new Table plugin provides parsing for table-like
1404 structured files, such as many files beneath /proc.
1405 * ted plugin: The new TED plugin reads power consumption measurements
1406 from “The Energy Detective” (TED). Thanks to Eric Reed for this
1407 plugin.
1408 * onewire plugin: The new `Interval' option allows collecting
1409 information from OneWire sensors at arbitrary intervals.
1410 * ping plugin: Support for collecting the drop rate and standard
1411 deviation of round-trip times has been added.
1412 * uptime plugin: The new uptime plugin can collect the server's
1413 uptime. Thanks to Marco Chiappero for the patch.
1415 2009-09-10, Version 4.6.5
1416 * collectd: Remove old values when a cache entry is marked as missing.
1417 This way the “GETVAL” command of the UnixSock plugin doesn't return
1418 old, no longer valid values when this happens. Thanks to Andrés J.
1419 Díaz for the patch.
1420 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1421 to follow redirects. Thanks to Joey Hess for reporting this bug.
1422 * df plugin: Check the ignorelist before stating the file system,
1423 possibly reducing the number of stats considerably. Thanks to Joey
1424 Hess for reporting this bug.
1425 * iptables plugin: Support for the new libiptc API has been added.
1426 Thanks to Sebastian Harl for the patch. The build system has been
1427 updated to the plugin only includes the shipped header files when it

1442 for reporting the bug.
1444 2009-06-02, Version 4.6.3
1445 * Build system, various plugins: Many build fixes for FreeBSD,
1446 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1447 for many fixes and providing a build system for many platforms,
1448 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1449 providing an OpenBSD system.
1450 * collectd: Two bugs with the threshold checking have been fixed. The
1451 first one prevented thresholds to be checked at all, the second one
1452 caused wrong behavior with the persistency option. Thanks to Andrés
1453 J. Díaz for fixing these problems.
1454 * collectd: Handling of the `Include' configuration option has been
1455 fixed.
1456 * battery plugin: Don't complain about a missing directory every
1457 interval.
1458 * exec plugin: Allow executed programs to close STDERR. Thanks to
1459 Thorsten von Eicken for reporting this problem.
1460 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1461 Tomasz Pala for the patch.
1462 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1463 the patch.
1464 * memory plugin: Fix a potential problem under Solaris.
1465 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1466 to Doug MacEachern for the patch.
1468 2009-03-18, Version 4.6.2
1469 * collectd: Some Solaris utility code has been improved.
1470 * filter subsystem: Allow `Chains' without default targets.
1471 * liboping: A patch to comply with strict aliasing rules has been
1472 added.
1473 * timediff match: Fix a typo: The match was registered with a wrong
1474 name which prevented this match to be used as documented. Thanks to
1475 Bruno Prémont for finding this problem.
1476 * bind plugin: Fix collection of the cached RR sets. The number of RR
1477 sets currently in the cache was collected as a counter value, which
1478 is nonsense. Thanks to Bruno Prémont for implementing this.
1479 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1480 primarily BSDs, don't take it well and crash.
1481 * oracle plugin: Portability to 64 bit systems has been improved.
1482 * postgresql plugin: The default configuration has been improved.
1483 * rrdtool plugin: Fix a possible race condition: If the network plugin
1484 is brought and dispatches a value before the rrdtool plugin is
1485 initialized, the daemon may crash.
1487 2009-02-22, Version 4.6.1
1488 * collectd: Many documentation fixes.
1489 * Collectd::Unixsock: Error handling has been improved.

1491 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1492 for finding and fixing most of them.
1493 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1494 faults. Thanks to Peter Holik for his patch.
1496 2009-02-16, Version 4.6.0
1497 * collectd: Added the `filter chain' infrastructure, which allows the
1498 user to use `matches' and `targets' to control value processing.
1499 * collectd: The new `-T' command line argument allows more in-depth
1500 testing of a configuration. Thanks to Doug MacEachern for the patch.
1501 * collectd-nagios: The Nagios integration command has been updated to
1502 use libcollectdclient. The `percentage' aggregation function has
1503 been added. Thanks to Fabian Linzberger for the patch.
1504 * libcollectdclient: A library which abstracts communication with the
1505 unixsock plugin for clients has been added.
1506 * regex match: Match values by their identifies using regular
1507 expressions.
1508 * timediff match: Match for values with an invalid timestamp.
1509 * value match: Select values by their data sources' values.
1510 * notification target: Create and dispatch a notification.
1511 * replace target: Replace parts of an identifier using regular
1512 expressions.
1513 * set target: Set (overwrite) entire parts of an identifier.
1514 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1515 statistics, allowing very detailed name server statistics. Thanks to
1516 Bruno Prémont for this plugin.
1517 * cpu plugin: Report `interrupt' separately when using
1518 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1519 example for native OpenBSD support, has been added. Thanks to Simon
1520 Kuhnle for the patch.
1521 * csv plugin: Make it possible to write values to STDOUT instead of
1522 files. This is meant for testing purposes mostly. The output written
1523 to STDOUT is compatible with the exec plugin. Thanks to Doug
1524 MacEachern for the patch.
1525 * curl plugin: This new plugin can be used to read web pages and parse
1526 them using the same mechanism that's used in the tail plugin.
1527 * dbi plugin: This new plugin allows you to connect to a variety of
1528 relational databases and use SQL to gather custom statistics from
1529 it. It is similar to the already existing PostgreSQL plugin but uses
1530 libdbi to communicate with the database(s).
1531 * interface plugin: Use the ignorelist framework when selecting /
1532 ignoring interfaces. This allows one to use regular expressions to
1533 select interfaces, too.
1534 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1535 Thanks to Bruno Prémont for this patch.
1536 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1537 for the patch.

1539 socket, too. Thanks to Mirko Buffoni for the patch.
1540 * network plugin: Further performance improvements for the receive
1541 code. This hopefully will help very large setups.
1542 * openvpn plugin: This new plugin collects statistics provided by the
1543 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1544 * oracle plugin: This new plugin allows you to connect to an Oracle
1545 database and use SQL to gather custom statistics from it. It is
1546 similar to the already existing PostgreSQL plugin.
1547 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1548 have been added.
1549 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1550 * perl plugin: Added support for `notification meta data'.
1551 * perl plugin: Added support for the `filter chain' infrastructure by
1552 allowing plugins to register `matches' and `targets'.
1553 * postgresql plugin: The preferred configuration syntax has been
1554 updated to be in line with the syntax used by the new dbi and oracle
1555 plugins. The compatibility code for the old syntax is present.
1556 Support for the new `Result' blocks and the interval parameter has
1557 been added.
1558 * processes plugin: Stacksize and virtual memory usage statistics have
1559 been added. Portability fixes.
1560 * rrdcached plugin: This new plugin uses the (still in development)
1561 RRD accelerator daemon, rrdcached. This daemon works very similar to
1562 the original rrdtool plugin of collectd, but adds some more nice
1563 features.
1564 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1565 added.
1567 2009-05-09, Version 4.5.4
1568 * Build system, various plugins: Many build fixes for FreeBSD,
1569 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1570 for many fixes and providing a build system for many platforms,
1571 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1572 providing an OpenBSD system.
1573 * collectd: Fix a potential race condition when creating directories.
1574 * battery plugin: Don't complain about a missing directory every
1575 interval.
1576 * dns plugin: Slight portability fixes.
1577 * exec plugin: Allow executed programs to close STDERR. Thanks to
1578 Thorsten von Eicken for reporting this problem.
1579 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1580 Tomasz Pala for the patch.
1581 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1582 the patch.
1583 * rrdtool plugin: Fix a possible race condition: If the network plugin
1584 is initialized and dispatches a value before the rrdtool plugin is
1585 initialized, the daemon may crash.
1586 * memory plugin: Fix a potential problem under Solaris.
1588 2009-02-22, Version 4.5.3
1589 * build system: The check for libupsclient even when `pkg-config' is
1590 not available.
1591 * collectd: Fix error handling in the global cache.
1592 * Collectd::Unixsock: Error handling has been improved.
1593 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1594 patch.
1595 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1596 faults. Thanks to Peter Holik for his patch.
1597 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1598 code. Thanks to "thated" for reporting this.
1600 2009-01-02, Version 4.5.2
1601 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1602 file may be in both locations, especially when the database was
1603 installed in a non-standard path. Thanks to Dusty Doris for
1604 reporting this.
1605 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1606 Solaris, in the configure script automatically.
1607 * build system, tcpconns plugin: Check for `kvm_nlist' and
1608 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1609 library with similar functions to the BSD variant, but doesn't
1610 provide these necessary functions.
1611 * collectd.conf(5): Various fixes and clarifications.
1612 * collectd: Remove a GNUism (unnamed unions), thus improving
1613 portability.
1614 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1615 This solves portability problems, especially for Solaris.
1616 * dns plugin: Fix a portability problem with NetBSD.
1617 * filecount plugin: Fix an off-by-one error. This error may cause a
1618 segmentation fault.
1619 * network plugin: Fix the handling of `type' in the network protocol.
1620 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1621 much larger buffer. This caused the `type' to be transferred much
1622 more often than necessary. In some cases, e. g. the `cpu' and
1623 `cpufreq' plugins being used at the same time, data may be corrupted
1624 in those files. Thanks to Bruno Prémont for debugging and reporting
1625 this issue.
1626 * processes plugin: Fix a possible segmentation fault when specifying
1627 invalid configuration options.
1628 * unixsock plugin: Make sure the initialization function is run only
1629 once. This resolves a file descriptor leak under systems which run
1630 the initialization more than once, such as Solaris.
1632 2008-10-16, Version 4.5.1
1633 * build system: Change `--enable-<plugin>' to abort with an error if
1634 dependencies are not met. Thanks to Bruno Prémont for the patch.
1635 Also, the poisoning of various string functions has been restricted
1636 to debug builds.
1637 * collectd: Fix a memory leak in the global value cache. With every
1638 *missing* value a couple of bytes would be leaked. Another memory
1639 leak in the configuration handling code has been fixed. Thanks to
1640 Niraj Tolia for reporting these issues.
1641 * collectd: Fix an off-by-one error in the ignorelist functionality.
1642 When using regular expressions, the last character would be missing,
1643 possibly matching differently from what one would expect.
1644 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1645 problem.
1646 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1647 Linzberger for reporting the bug.
1648 * iptables plugin: Fix an off-by-one error. If a string was just one
1649 character too long, it was truncated instead of reporting an error.
1650 * network plugin: Fix a memory leak in the configuration handling
1651 code. Thanks to Niraj Tolia for reporting this issue.
1652 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1653 * postgresql plugin: Don't reopen connection during reinitialization.
1654 This fixes a bug under Solaris and potentially other platforms.
1655 Missing calls to `PQclear' have been added, too. This fixes memory
1656 leaks. Thanks to ``Admin'' for reporting these bugs.
1657 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1658 library.
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.
1663 2008-09-04, Version 4.5.0
1664 * collectd: Added the ability to flush certain identifiers.
1665 * collectd: The concept of `notification meta data' has been
1666 introduced.
1667 * filecount plugin: The new filecount plugin counts the number of
1668 files in a directory and its subdirectories.
1669 * ipmi plugin: Sensor names have been changed to ensure unique names.
1670 Notifications upon added and removed sensors can now be generated.
1671 * notify_desktop plugin: This new plugin sends notifications to the
1672 X desktop using the structure defined in the `Desktop Notification
1673 Specification'.
1674 * notify_email plugin: This new plugin sends out notifications via
1675 email, using the `esmtp' library.
1676 * onewire plugin: The new experimental(!) onewire plugin reads values,
1677 such as temperatures, from sensors connected to the computer via the
1678 onewire bus.
1679 * perl plugin: Improved synchronized access to internal data structures
1680 and fixed a possible dead-lock.
1681 * perl plugin: Added the ability to flush certain identifiers and marked
1682 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1683 plugin_flush().
1684 * perl plugin: Added the ability to configure Perl plugins.
1685 * postgresql plugin: The new postgresql plugin collects statistics
1686 about or from a PostgreSQL database.
1687 * processes plugin: The `ProcessMatch' option has been added.
1688 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1689 IO load.
1690 * tcpconns plugin: This plugin has been ported to OpenBSD.
1691 * thermal plugin: The new thermal plugin collects system temperatures
1692 using Linux ACPI thermal zone data.
1694 2009-01-02, Version 4.4.5
1695 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1696 file may be in both locations, especially when the database was
1697 installed in a non-standard path. Thanks to Dusty Doris for
1698 reporting this.
1699 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1700 Solaris, in the configure script automatically.
1701 * collectd.conf(5): Various fixes and clarifications.
1702 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1703 portability problems, especially for Solaris.
1704 * dns plugin: Fix a portability problem with NetBSD.
1705 * network plugin: Fix the handling of `type' in the network protocol.
1706 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1707 much larger buffer. This caused the `type' to be transferred much
1708 more often than necessary. In some cases, e. g. the `cpu' and
1709 `cpufreq' plugins being used at the same time, data may be corrupted
1710 in those files. Thanks to Bruno Prémont for debugging and reporting
1711 this issue.
1712 * unixsock plugin: Make sure the initialization function is run only
1713 once. This resolves a file descriptor leak under systems which run
1714 the initialization more than once, such as Solaris.
1716 2008-10-16, Version 4.4.4
1717 * build system: Change `--enable-<plugin>' to abort with an error if
1718 dependencies are not met. Thanks to Bruno Prémont for the patch.
1719 Also, the poisoning of various string functions has been restricted
1720 to debug builds.
1721 * collectd: Fix a memory leak in the global value cache. With every
1722 *missing* value a couple of bytes would be leaked. Another memory
1723 leak in the configuration handling code has been fixed. Thanks to
1724 Niraj Tolia for reporting these issues.
1725 * collectd: Fix an off-by-one error in the ignorelist functionality.
1726 When using regular expressions, the last character would be missing,
1727 possibly matching differently from what one would expect.
1728 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1729 problem.
1730 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1731 Linzberger for reporting the bug.
1732 * network plugin: Fix a memory leak in the configuration handling
1733 code. Thanks to Niraj Tolia for reporting this issue.
1734 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1735 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1736 problems with some `libc's. Thanks to Matthias Lay for reporting the
1737 bug.

1748 * collectd: Try even harder to determine the endianess of the
1749 architecture collectd is being built on.
1750 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1751 of disks.
1752 * dns plugin: Fix compilation errors with BIND versions 19991001
1753 through 19991005.
1754 * network plugin: Bugfix in the init routine: The init function
1755 cleared a buffer regardless of its contents. This could lead to lost
1756 values under Solaris.
1757 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1758 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1759 function.
1760 * wireless plugin: Work around incorrect noise and power values
1761 returned by some broken drivers.
1763 2008-06-03, Version 4.4.1
1764 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1765 to kyrone for reporting this.
1766 * collectd: Fixed min/max output in notifications generated by
1767 threshold checking.
1768 * collectd-nagios: Fix the protocol used to communicate with the
1769 daemon.
1770 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1771 initialization has errors. An issue with Perl 5.10 has been fixed.
1772 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1773 René Rebe and Siegmund Gorr for reporting this.
1775 2008-05-06, Version 4.4.0
1776 * collectd: Internal code cleanups.
1777 * collectd: Added support for a `Flush' command in the unixsock and
1778 exec plugins. This command can be used to force a plugin (or all) to
1779 flush its values to disk.
1780 * collectd: Thresholds can now be configured to apply to one data
1781 source only, making it possible to configure different thresholds
1782 for each data source.
1783 * apache, nginx plugins: Added the possibility to disable host and/or
1784 peer verification.
1785 * ascent plugin: The new ascent plugin reads and parses the statistics
1786 page of an Ascent server.
1787 * cpu plugin: Support for the statgrab library has been added.
1788 * disk plugin: The possibility to ignore certain disks or collect only
1789 specific disks has been added.

1791 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1792 sensor values via IPMI, the intelligent platform management
1793 interface.
1794 * iptables plugin: The iptc library that is used by the iptables
1795 plugin has been added to the distribution, because it is not
1796 provided by all distributions and removed from at least one.
1797 * powerdns plugin: The new powerdns plugin reads statistics from an
1798 authoritative or a recursing PowerDNS name server.
1799 * rrdtool plugin: The size of the files generated with the default
1800 configuration has been decreased.
1801 * tail plugin: The new tail plugin can be used to gather statistics by
1802 continuously reading from log files.
1803 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1804 TeamSpeak2 server and collects statistics about the number of users
1805 and number of channels.
1806 * users plugin: Support for the statgrab library has been added.
1807 * vmem plugin: The new vmem plugin collects very detailed statistics
1808 about the virtual memory subsystem of Linux.
1810 2008-08-30, Version 4.3.4
1811 * Build system: Improved detection of and linking with the statgrab
1812 library.
1813 * collectd: Portability fixes, especially to determine endianess more
1814 reliable.
1815 * Various plugins: Fix format strings.
1816 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1817 again has been applied.
1818 * memcached plugin: Fix a too short timeout and a related file
1819 descriptor leak.
1820 * memory plugin: A typo in the libstatgrab code has been fixed.
1821 * network plugin: A fix in the initialization function solves problems
1822 under Solaris.
1823 * nginx plugin: A thread-unsafe function has been replaced.
1824 * vserver plugin: A thread-unsafe function has been replaced.
1825 * wireless plugin: A work-around for broken wireless drivers has been
1826 added.
1828 2008-04-22, Version 4.3.3
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 4.3.2
1844 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1845 `Persist' threshold options.
1846 * collectd: Fix handling of missing values in the global value cache.
1847 * collectd: Improved error messages when parsing the configuration.
1848 * sensors plugin: Fix temperature collection with libsensors4.
1849 * unixsock plugin: Fix mixed input and output operation on streams.
1850 * wireless plugin: Fix reading noise value.
1852 2008-03-05, Version 4.3.1
1853 * exec plugin: Set supplementary group IDs.
1854 * network plugin:
1855 + Use `memcpy' when constructing/parsing a package to avoid
1856 alignment problems on weird architectures, such as Sparc.
1857 + Translate doubles to/from the x86 byte representation to ensure
1858 cross-platform compatibility.
1859 * ping plugin: Correct the handling of the `TTL' setting.
1860 * swap plugin: Reapply a patch for Solaris.
1861 * tcpconns plugin: Portability improvements.
1863 2008-02-18, Version 4.3.0
1864 * collectd: Notifications have been added to the daemon. Notifications
1865 are status messages that may be associated with a data instance.
1866 * collectd: Threshold checking has been added to the daemon. This
1867 means that you can configure threshold values for each data
1868 instance. If this threshold is exceeded a notification will be
1869 created.
1870 * collectd: The new `FQDNLookup' option tells the daemon to use the
1871 full qualified domain name as the hostname, not just the host part
1872 es returned by `gethostname(2)'.
1873 * collectd: Support for more than one `TypesDB' file has been added.
1874 This is useful when one such file is included in a package but one
1875 wants to add custom type definitions.
1876 * collectd: The `Include' config option has been expanded to handle
1877 entire directories and shell wildcards.
1878 * collectdmon: The new `collectdmon' binary detects when collectd
1879 terminates and automatically restarts it again.
1880 * csv plugin: The CSV plugin is now able to store counter values as a
1881 rate, using the `StoreRates' configuration option.
1882 * exec plugin: Handling of notifications has been added and the
1883 ability to pass arguments to the executed programs has been added.
1884 * hddtemp plugin: The new `TranslateDevicename' option lets you
1885 disable the translation from device names to major-minor-numbers.
1886 * logfile plugin: Handling of notifications has been added.
1887 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1888 domain name lookups in this plugin.
1889 * perl plugin: Many internal changes added support for handling multiple
1890 threads making the plugin reasonably usable inside collectd. The API has
1891 been extended to support notifications and export global variables to
1892 Perl plugins; callbacks now have to be identified by name rather than a
1893 pointer to a subroutine. The plugin is no longer experimental.
1894 * uuid plugin: The new UUID plugin sets the hostname to an unique
1895 identifier for this host. This is meant for setups where each client
1896 may migrate to another physical host, possibly going through one or
1897 more name changes in the process. Thanks to Richard Jones from
1898 Red Hat's Emerging Technology group for this plugin.
1899 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1900 CPU, disk and network statistics about guest systems on the same
1901 physical server. Thanks to Richard Jones from Red Hat's Emerging
1902 Technology group for this plugin.
1904 2008-04-22, Version 4.2.7
1905 * build system: Improved detection of several libraries, especially if
1906 they are in non-standard paths.
1907 * build system: Portability fixes: Automatically define "_REENTRANT"
1908 if the libc expects it.
1909 * collectd: Error and warning messages have been improved.
1910 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1911 using them.
1912 * apache plugin: Allocate new memory when reading a webpage instead of
1913 using a buffer of static size.
1914 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1915 the program.
1916 * hddtemp plugin: Error and warning messages have been improved.
1917 * sensors plugin: Fix sensor collection for some chip types.
1919 2008-03-29, Version 4.2.6
1920 * collectd: Improved error messages when parsing the configuration.
1921 * sensors plugin: Fix temperature collection with libsensors4.
1922 * unixsock plugin: Fix mixed input and output operation on streams.
1923 * wireless plugin: Fix reading noise value.
1925 2008-03-04, Version 4.2.5
1926 * apache plugin: Improved initialization and error messages.
1927 * exec plugin: Set supplementary group IDs.
1928 * network plugin:
1929 + Create separate threads for reading from the socket and parsing
1930 and dispatching incoming packets. Versions prior to this may have
1931 problems in high-load situations, where the socket receive buffers
1932 overflows, resulting in gaps in the data.
1933 + Use `memcpy' when constructing/parsing a package to avoid
1934 alignment problems on weird architectures, such as Sparc.
1935 + Translate doubles to/from the x86 byte representation to ensure
1936 cross-platform compatibility.
1937 * ping plugin: Correct the handling of the `TTL' setting.
1938 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1939 * swap plugin: Reapply a patch for Solaris.
1940 * tcpconns plugin: Portability improvements.
1942 2008-01-21, Version 4.2.4
1943 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1944 the permission on the socket as documented in the manpage. Thanks to
1945 Evgeny Chukreev for fixing this issue.
1946 * collectd: The documentation has been improved.
1948 2007-12-28, Version 4.2.3
1949 * sensors plugin: Updated the plugin to build and work with version 3
1950 of the libsensors library.
1952 2007-12-15, Version 4.2.2
1953 * nginx plugin: Incorrect comparison of strings lead to a segfault
1954 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1955 this.
1956 * logfile plugin: The config option `Timestamp' was handled
1957 incorrectly and basically always active. Thanks to Luke Heberling
1958 for fixing this.
1960 2007-11-08, Version 4.2.1
1961 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1962 enabled on the host.
1963 * snmp plugin: Fix a memory leak.
1965 2007-10-27, Version 4.2.0
1966 * collectd: The new config option `Include' lets you include other
1967 configfiles and thus split up your config into smaller parts. This
1968 may be especially interesting for the snmp plugin to keep the data
1969 definitions separate from the host definitions.
1970 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1971 (number of connections, octets and packets for each service and
1972 destination). Thanks to Sebastian Harl for this plugin.
1973 * memcached plugin: The new `memcached' plugin connects to a memcached
1974 daemon process and collects statistics of this distributed caching
1975 system. Thanks to Antony Dovgal for contributing this plugin.
1976 * nginx plugin: The new `nginx' plugin reads the status page of an
1977 nginx daemon and saves the handled connections and requests.
1978 * perl plugin: Many changes, including the added `EnableDebugger'
1979 config option which lets you debug your Perl plugins more easily.
1980 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1981 be more thread-safe otherwise by locking calls to the library.
1982 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1983 correct the values returned by SNMP-agents. If a <data> block is
1984 defined as `table' the instance is now optional. The sequence number
1985 is used as the type-instance in this case. The new `InstancePrefix'
1986 option allows to add arbitrary prefixes to the type-instance.
1987 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1988 certain TCP connections and what state they're in. This can be used
1989 to see how many connections your FTP server has to handle or how
1990 many outgoing connections your mailserver has open.
1992 2008-01-11, Version 4.1.6
1993 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1994 the permission on the socket as documented in the manpage. Thanks to
1995 Evgeny Chukreev for fixing this issue.
1996 * collectd: The documentation has been improved.
1998 2007-12-27, Version 4.1.5
1999 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
2000 memory situations.
2001 * sensors plugin: Updated the plugin to build and work with version 3
2002 of the libsensors library.
2004 2007-11-08, Version 4.1.4
2005 * Build system: Improve detection of the rrd library, especially if
2006 it's in a non-standard location.
2007 * Build system: A bug when parsing the argument for
2008 `--with-libnetsnmp' has been fixed.
2009 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2010 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2011 a deadlock or delay when shutting down the daemon.
2012 * snmp plugin: Fix a memory leak.
2014 2007-10-24, Version 4.1.3
2015 * collectd: A build issue under Solaris has been resolved by renaming
2016 data types.
2017 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2018 be more thread-safe otherwise by locking calls to the library.
2020 2007-09-28, Version 4.1.2
2021 * apcups plugin: Fix reporting of the `load percent' data.
2022 * wireless plugin: Correct the handling of cards returning signal and
2023 noise quality as percentage.
2024 * perl plugin: Fix a possible buffer overflow in get_module_name().
2025 * build system: Further improve the detection of libraries.
2026 * netlink plugin: Build issues under some older versions of the Linux
2027 includes (i. e. Debian Sarge) have been fixed.
2028 * snmp plugin: Fix a potential segfault when a host times out. Add
2029 support for the `timeticks' type.
2031 2007-09-12, Version 4.1.1
2032 * Build system: The detection of `libnetlink' has been improved.
2033 * collectd: The documentation has been fixed in numerous places.
2034 * exec plugin: Setting the group under which to run a program has been
2035 fixed.
2036 * collectd: The `sstrerror' function was improved to work correctly
2037 with the broken GNU version of `strerror_r'.
2038 * collectd: Write an error message to STDERR when loading of a plugin
2039 fails.
2040 * apcups plugin: Fix the `types' used to submit the values: They still
2041 has an `apcups_' prefix which doesn't work anymore.
2042 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2043 whatever the client thinks is `now'..
2045 2007-09-01, Version 4.1.0
2046 * Build system: The build system has been changed to automatically
2047 disable all plugins, which are missing dependencies. The dependency
2048 checking has been removed from the plugins themselves to remove
2049 redundancy.
2050 * Flexible interval: The interval of collected data is now sent along
2051 with the data itself over the network, so that the interval-settings
2052 of server and clients no longer needs to match.
2053 * netlink plugin: The new `netlink' plugin connects to the Linux
2054 kernel using a netlink socket and uses it to query information about
2055 interfaces, qdiscs and classes.
2056 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2057 to not block data collection.
2058 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2059 network devices, such as switches, routers, thermometers, rack
2060 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2061 plugin.
2062 * unixsock plugin: Added the `LISTVAL' command.
2063 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2064 of music played with xmms.
2066 2007-09-28, Version 4.0.9
2067 * apcups plugin: Fix reporting of the `load percent' data.
2068 * wireless plugin: Correct the handling of cards returning signal and
2069 noise quality as percentage.
2070 * perl plugin: Fix a possible buffer overflow in get_module_name().
2072 2007-09-12, Version 4.0.8
2073 * collectd: The `sstrerror' function was improved to work correctly
2074 with the broken GNU version of `strerror_r'.
2075 * collectd: Write an error message to STDERR when loading of a plugin
2076 fails.
2077 * apcups plugin: Fix the `types' used to submit the values: They still
2078 has an `apcups_' prefix which doesn't work anymore.
2079 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2080 whatever the client thinks is `now'..
2082 2007-08-26, Version 4.0.7
2083 * documentation: Some typos have been fixed and some information has
2084 been improved.
2085 * build system: Many fixes for detecting libraries in unusual places,
2086 such as on RedHat systems. The affected libraries are `libcurl',
2087 `libmysql', and `libupsclient'.
2088 * network plugin: Allow the `Port' option to be specified as a number
2089 (i. e. without quotes).
2090 * nut plugin: A fix allows linking the nut plugin against
2091 libupsclient, version >= 2.2.0.
2092 * processes plugin: Fix a potential segmentation fault.
2094 2007-07-30, Version 4.0.6
2095 * sensors plugin: Fix the ignorelist functionality: Only the `type
2096 instance' was used to match against the list, but the documentation
2097 told otherwise. This release fixes the code, so it complies with the
2098 documentation.
2099 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2100 configuration messages will end up in the logging facility.
2101 * conrtib/fedora: The contributed specfile for Fedora has been
2102 updated.
2104 2007-07-05, Version 4.0.5
2105 * Portability: More fixes for OpenBSD have been included.
2107 2007-06-24, Version 4.0.4
2108 * cpu plugin: Fixed the Solaris code.
2109 * dns plugin: Fixed a build issue for OpenBSD.
2110 * interface plugin: Fixed the Solaris code.
2111 * load plugin: Fixed the alternative `/proc' Linux code.
2112 * memory plugin: Fixed the Solaris code.
2113 * oconfig: Don't require `-lfl' anymore.
2115 2007-06-19, Version 4.0.3
2116 * cpu plugin: Fix the Darwin / Mac OS X code.
2117 * ping plugin: Use the return value of `getpid', not its address.
2118 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2119 initialized correctly.
2120 * configure: Added `--with-nan-emulation' to aid cross compilation.
2122 2007-06-12, Version 4.0.2
2123 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2124 they're given in numerically form.
2126 2007-06-07, Version 4.0.1
2127 * iptables plugin: A bug in the configuration routine has been fixed.
2128 Setting a comment in the configfile will no longer cause a
2129 segmentation fault.
2131 2007-06-03, Version 4.0.0
2132 * collectd: The plugin-infrastructure has been changed to allow for
2133 more types of plugins, namely `write' and `log' plugins.
2134 * collectd: The read-function has been changed to read many plugins in
2135 parallel, using threads. Thus, plugins generally need to use
2136 thread-safe functions from now on.
2137 * collectd: The '-t' command line options allows to perform syntax tests
2138 of the configuration file and exit immediately.
2139 * csv plugin: The new `csv' plugin handles output to `comma separated
2140 values'-files.
2141 * rrdtool plugin: The new `rrdtool' plugin handles output to
2142 RRD-files. Data can be cached to combine multiple updates into one
2143 write to increase IO-performance.
2144 * network plugin: The new `network' plugin handles IO via the network.
2145 It implements a different, much more extensible protocol which can
2146 combine many values in one packet, decreasing the number of UDP-
2147 packets being sent. It can read from and send to the network and
2148 with the appropriate configuration even forward packets to other
2149 networks.
2150 * unixsock plugin: The new `unixsock' plugin provides an interface to
2151 communicate with the daemon while it is running. Right now the
2152 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2153 come.
2154 * perl plugin: The new `perl' plugin allows you to write extensions
2155 for collectd in the scripting-language Perl.
2156 * logfile plugin: The new `logfile' plugin writes logmessages to files
2157 or STDOUT or STDERR.
2158 * syslog plugin: The new `syslog' plugin sends logmessages to the
2159 system's syslog daemon.
2160 * entropy plugin: The new `entropy' plugin collects the amount of
2161 entropy currently being available to the system.
2162 * exec plugin: The new `exec' plugin forks child processes and reads
2163 back values provided by the forked processes.
2164 * iptables plugin: The new `iptables' plugin reads counters from
2165 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2166 plugin.
2167 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2168 to Peter Holik for contributing this plugin.
2169 * nut plugin: The new `nut' plugin connects the upsd of the `network
2170 ups tools' and reads information about the connected UPS.
2171 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2172 connections) field was added by Florent Monbillard.
2173 * collectd-nagios: The new `collectd-nagios' binary queries values
2174 from collectd, parses them and exits according to Nagios-standards.
2175 * manpages: The manpages have been improved a lot.
2177 2007-09-28, Version 3.11.7
2178 * wireless plugin: Correct the handling of cards returning signal and
2179 noise quality as percentage.
2181 2007-08-31, Version 3.11.6
2182 * processes plugin: Fix a potential segmentation fault.
2184 2007-05-29, Version 3.11.5
2185 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2186 * ntpd plugin: Fix a potential buffer overflow.
2187 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2188 were accounted as `zombies'.
2190 2007-04-10, Version 3.11.4
2191 * dns plugin: Change the order of includes to make the plugin compile
2192 under FreeBSD.
2194 2007-03-30, Version 3.11.3
2195 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2196 of the unused `COLLECT_KSTAT'.
2198 2007-02-11, Version 3.11.2
2199 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2200 NULL-pointer may have been passed to `printf' which causes a
2201 segfault with some libcs.
2203 2007-02-10, Version 3.11.1
2204 * df plugin: Some wrong defines have been fixed so the plugin works
2205 under Solaris again.
2206 * dns plugin: The usage of a struct has been fixed to work with
2207 non-GNU libcs.
2208 * processes plugin: Some missing defines have been added so the plugin
2209 compiles cleanly under FreeBSD and presumably other UNIXes.
2211 2006-12-22, Version 3.11.0
2212 * collectd: The new command line option `-P' makes it easier for
2213 distributors to change the location of PID-files.
2214 * collectd: The daemon shuts down faster now which makes it easier to
2215 write init.d-scripts for it.
2216 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2217 caused problems every now and then.
2218 * df plugin: New config options allow to ignore certain mountpoints,
2219 filesystem types or devices.
2220 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2221 and interprets it. It collects traffic as well as qtype, opcode and
2222 rcode counts.
2223 * email plugin: Sebastian Harl has contributed this plugin which
2224 counts received mails in categories (e. g. ham, spam, virus), spam
2225 score (as given by SpamAssassin) and check types.
2226 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2227 uses `mbmon' to gather information from sensors on the motherboard.
2228 * processes plugin: Collect detailed statistics for configured
2229 processes, that's process and thread count, CPU usage, resident
2230 segment size and pagefaults.
2231 * multimeter plugin: Peter Holik contributed a new plugin which
2232 queries multimeters.
2233 * sensors plugin: Lubos Stanek has put much effort into improving this
2234 plugin, including `extended naming', collection of voltage values
2235 and the possibility to ignore certain values.
2237 2006-12-21, Version 3.10.4
2238 * Max Kellermann has identified a bug in the server routine: When
2239 opening a socket fails the daemon will (re)try opening the socket in
2240 an endless loop, ultimately leading to a `EMFILE' error.
2242 2006-11-04, Version 3.10.3
2243 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2244 ntpd's reply was sent in more than one packet, the buffer size was
2245 calculated incorrectly, resulting in the reading of uninitialized or
2246 freed memory.
2248 2006-11-01, Version 3.10.2
2249 * The sample config file has been improved.
2250 * Errors in the manpages have been corrected.
2251 * The ping-plugin now adds hosts during initialization, not during
2252 startup. This speeds up startup when no network connectivity is
2253 available. Also, the hosts are being added later when the network is
2254 available.
2255 * Improved BSD-support for the df-plugin.
2256 * Fixed syntax errors in the swap-plugin for Mac OS X.
2257 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2258 plugin.
2259 * Don't disable the mysql-plugin if connecting to the database fails
2260 during initialization. Instead, try again in increasing intervals.
2262 2006-07-19, Version 3.10.1
2263 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2264 the apcups cannot be reached, unconnected sockets will pile up and
2265 eventually lead to `Too many open files' errors.
2267 2006-07-09, Version 3.10.0
2268 * The `disk' plugin has been ported to Darwin.
2269 * The `battery' plugin should work on many Apple computers now.
2270 * The `traffic' plugin can now ignore certain interfaces. Also,
2271 statistics for sent/received packets and errors have been added.
2272 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2273 to Anthony Gialluca for contributing this plugin and providing me
2274 with a test environment :)
2275 * A plugin for monitoring an NTP instance and the local clock drift
2276 has been added.
2278 2006-06-25, Version 3.9.4
2279 * The Solaris code in the `swap' plugin has been changed to reflect
2280 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2281 working this out.
2282 * The debugging system has been fixed to work with the Sun libc.
2283 * When built without librrd the variable `operating_mode' could be
2284 uninitialized. Thanks to David Elliot for reporting the bug.
2286 2006-06-01, Version 3.9.3
2287 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2288 operating systems also profit from the changes, but I wasn't able to
2289 check that.
2290 * Changed the build system to find the netinet-includes under FreeBSD
2291 and therefore successfully build the `liboping' library there.
2293 2006-05-09, Version 3.9.2
2294 * Applied a patch to the `liboping' library. Due to a bug in the
2295 sequence checking the `ping' plugin stopped working after
2296 approximately 7.6 days.
2298 2006-05-09, Version 3.8.5
2299 * Applied a patch to the `liboping' library. Due to a bug in the
2300 sequence checking the `ping' plugin stopped working after
2301 approximately 7.6 days.
2303 2006-04-21, Version 3.9.1
2304 * Build issues with Solaris and possible other architectures have been
2305 resolved.
2306 * Problems when building the `apache'-plugin without `libcurl' have
2307 been resolved.
2308 * A bug in the `ping' plugin has been fixed. Sorry folks.
2310 2006-04-02, Version 3.9.0
2311 * A plugin to monitor the Apache webserver has been added.
2312 <http://httpd.apache.org/>
2313 * A plugin to collect statistics about virtual servers using VServer.
2314 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2315 this plugin :)
2316 * A plugin for wireless LAN cards has been added. It monitors signal
2317 strength, link quality and noise ratio..
2318 * A plugin for Apple hardware sensors has been added.
2319 * An option to compile collectd with different `step' and `heartbeat'
2320 settings has been added. The size of RRAs is no longer static but
2321 calculated based on the settings for `step' and `width'.
2322 * The `ping' plugin can now be configured to use a certain TTL.
2323 * A plugin to monitor the hardware sensors of Apple computers has been
2324 added.
2325 * The plugins `cpu', `memory', `processes' and `traffic' have been
2326 ported to Mach/Darwin (Mac OS X).
2327 * The `log mode' has been contributed by Christophe Kalt. It writes
2328 the data into text files rather than RRD files.
2330 2006-04-09, Version 3.8.4
2331 * Applied patch by Vincent Stehlé which improves the disk-name
2332 resolution in the `hddtemp' plugin for Linux systems.
2334 2006-04-02, Version 3.8.3
2335 * Applied a patch by James Byers: The MySQL plugin was not working
2336 with MySQL 5.0.2 or later.
2338 2006-03-14, Version 3.8.2
2339 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2340 the GNU libc, because it points to `/etc/fstab' rather than
2341 `/etc/mtab'.
2343 2006-03-13, Version 3.8.1
2344 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2345 * Fixes in the debian `postinst' and `init.d' scripts.
2347 2006-03-09, Version 3.8.0
2348 * The `ping' plugin no longer uses `libping' but a self written
2349 library named `liboping'. With this library it's possible to ping
2350 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2352 2006-02-18, Version 3.7.2
2353 * A simple bug in the `battery' plugin has been fixed. It should now
2354 work with ACPI based batteries as well. Thanks to Sebastian for
2355 fixing this.
2356 * Fixing a bug that prevented collectd to be built without librrd.
2357 Thanks to Werner Heuser for reporting it.
2359 2006-02-04, Version 3.7.1
2360 * The new network code has been improved to build with older versions
2361 of glibc.
2362 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2363 to Tommie Gannert for this patch.
2365 2006-01-30, Version 3.7.0
2366 * The `battery' plugin has been added. It collects information about
2367 laptop batteries..
2368 * The MySQL plugin has been improved: It now writes two more RRD
2369 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2370 * The `cpufreq' plugin now reads another file since the file it did
2371 read so far causes much overhead in the kernel. Also, you need root
2372 to read the old file, but not to read the new one.
2373 * The `hddtemp' plugin can now be configured to connect to another
2374 address and/or port than localhost.
2375 * The `df' plugin now prefers `statvfs' over `statfs'.
2376 * The network code has been rewritten. collectd now supports unicast
2377 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2378 be set in the configfile.
2380 2006-01-24, Version 3.6.2
2381 * Due to a bug in the configfile handling collectd wouldn't start in
2382 client mode. This released fixes this.
2384 2006-01-20, Version 3.6.1
2385 * Due to a bug in `configure.in' all modules and the binary were
2386 linked against `libmysqlclient'. This issue is solved by this
2387 release.
2389 2006-01-17, Version 3.6.0
2390 * A config file has been added. This allows for loading only specific
2391 plugins.
2392 * A `df' plugin has been added.
2393 * A `mysql' plugin has been added.
2394 * The `ping' plugin doesn't entirely give up hope when a socket error
2395 occurred, but will back of and increase the intervals between tries.
2397 2006-01-21, Version 3.5.2
2398 * Fixed yet another bug in the signal handling.. Stupid typo..
2399 * Improved the ping plugin to not give up on socket errors (backport
2400 from 3.6.0).
2402 2005-12-18, Version 3.5.1
2403 * The PID-file is now deleted correctly when shutting down the daemon.
2404 * SIGINT and SIGTERM are now handled correctly.
2406 2005-12-16, Version 3.5.0 (Revision 326)
2407 * A bug in the `load' module under Solaris has been fixed.
2408 * The `users' module has been contributed by Sebastian Harl. It counts
2409 currently logged in users.
2410 * The CPU module now works under FreeBSD without the use of
2411 `libstatgrab', however SMP support is missing.
2412 * The default directories for the RRD files and the PID file now
2413 depend on the compile time setting of `localstatedir'.
2415 2005-11-15, Version 3.4.0 (Revision 236)
2416 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2417 from gentoo's bugzilla for writing the patch.
2418 * The build dependency for librrd has been removed. Binaries built
2419 without librrd are client-only and will multicast their value as
2420 with the `-c' argument.
2421 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2422 * The newly introduced `-f' switch prevents daemon initialization
2423 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2424 Barcellos for this patch.
2426 2005-11-04, Version 3.3.0 (Revision 216)
2427 * New modules have been added:
2428 - `serial', for monitoring traffic on the serial interfaces
2429 - `nfs', for graphing NFS procedure calls
2430 - `tape', traffic from/to tape devices
2431 * The memory.rrd now accepts more than 4Gig of memory.
2433 2005-10-26, Version 3.2.0 (Revision 200)
2434 * Support for graphing the processes has been added (thanks to Lyonel
2435 Vincent)
2436 * If reading from hddtemp fails collectd will increase the time
2437 between polls up to one day.
2438 * The init.d files have been improved.
2439 * Problems with the spec file have been fixed.
2441 2005-10-16, Version 3.1.0 (Revision 194)
2442 * Added the `setsid' syscall to the startup code.
2443 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2445 2005-09-30, Version 3.0.0 (Revision 184)
2446 * The ability to send/receive data to/from the network (think
2447 multicast) has been added.
2448 * Modules have been split up into shared libraries can be loaded at
2449 runtime. The biggest advantage is that the core program doesn't need
2450 to be linked against an external library.
2451 * A patch by George Kargiotakis has been applied: It fixes the sensors
2452 behaviour then more than one sensor is being queried.
2454 2005-09-16, Version 2.1.0 (Revision 172)
2455 * A module for swap statistics has been added.
2457 2005-09-09, Version 2.0.0 (Revision 135)
2458 * Filenames can no longer be configured at program startup. The only
2459 options as of this version are the directory and ping hosts.
2460 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2461 Soft-IRQ statistics are added to `System'.
2462 * Diskstats now collect read and write bytes, not sectors.
2463 * Ping statistics can now be collected for more than one host. There
2464 is no default any more: If no host is given no host will be pinged.
2465 * A self-written patch for libping has been applied so it builds
2466 cleanly.
2468 2005-09-01, Version 1.8.1 (Revision 123)
2469 * Much improved configure-script: libraries and features may now be
2470 disabled.
2471 * More detailed warnings/error messages when RRD update fails.
2473 2005-08-29, Version 1.8.0:
2474 * Support for collecting disk statistics under Solaris.
2476 2005-08-25, Version 1.7.0:
2477 * Support for libstatgrab[1] for load, memory usage and network
2478 traffic. CPU- and disk-usage are not (yet) supported, since
2479 libstatgrab returns insufficient information. I will contact the
2480 authors.
2481 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2482 aren't necessarily counted linear which is now handled correctly.
2483 [1]: http://www.i-scream.org/libstatgrab/
2485 2005-08-21, Version 1.6.0:
2486 * Basic support for Solaris: System load and cpu-usage can be
2487 collected under Solaris, too. Other stats will follow later.
2488 * Many fixes in the autoconf-script
2489 * Collection/Museum scripts have been added under contrib/museum
2490 * collectd may now be started in unprivileged mode, though ping
2491 statistics will not work.
2493 2005-07-17, Version 1.5.1:
2494 * Diskstats-RRDs now use major/minor for naming. Some systems have
2495 weird strings as disk-names..
2497 2005-07-17, Version 1.5:
2498 * A new module, diskstats, has been added. It collects information
2499 about the disks and partitions.
2501 2005-07-11, Version 1.4.2:
2502 * The meminfo module has been changed to work with more platforms
2503 and/or kernel versions.
2505 2005-07-10, Version 1.4.1: Correct traffic stats
2506 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2507 forgot to correct when I changed that module.
2509 2005-07-09, Version 1.4: More traffic stats
2510 * Traffic is now collected for all interfaces that can be found
2511 * Temperature-statistics are read from lm-sensors if available
2513 2005-07-08, Version 1.3: CPU stats
2514 * Collecting CPU statistics now
2516 2005-07-12, Version 1.2: Using syslog
2517 * collectd is now using the syslog facility to report errors, warnings
2518 and the like..
2519 * The default directory is now /var/db/collectd
2521 2005-07-10, Version 1.1: Minor changes
2522 * Nothing really useful to say ;)
2524 2005-07-09, Version 1.0: Initial Version
2525 * The following modules are provided:
2526 * Load average
2527 * Ping time
2528 * Traffic
2529 * Memory info
