1136 first one prevented thresholds to be checked at all, the second one
1137 caused wrong behavior with the persistency option. Thanks to Andrés
1138 J. Díaz for fixing these problems.
1139 * collectd: Handling of the `Include' configuration option has been
1140 fixed.
1141 * rrdtool plugin: Make sure initialization is run only once. This

1254 Bruno Prémont for finding this problem.
1255 * bind plugin: Fix collection of the cached RR sets. The number of RR
1256 sets currently in the cache was collected as a counter value, which
1257 is nonsense. Thanks to Bruno Prémont for implementing this.

1300 * csv plugin: Make it possible to write values to STDOUT instead of
1301 files. This is meant for testing purposes mostly. The output written
1302 to STDOUT is compatible with the exec plugin. Thanks to Doug
1303 MacEachern for the patch.
1304 * curl plugin: This new plugin can be used to read web pages and parse
1305 them using the same mechanism that's used in the tail plugin.
1306 * dbi plugin: This new plugin allows you to connect to a variety of
1307 relational databases and use SQL to gather custom statistics from
1308 it. It is similar to the already existing PostgreSQL plugin but uses
1309 libdbi to communicate with the database(s).
1310 * interface plugin: Use the ignorelist framework when selecting /
1311 ignoring interfaces. This allows one to use regular expressions to
1312 select interfaces, too.

1333 updated to be in line with the syntax used by the new dbi and oracle
1334 plugins. The compatibility code for the old syntax is present.
1335 Support for the new `Result' blocks and the interval parameter has
1336 been added.
1337 * processes plugin: Stacksize and virtual memory usage statistics have
1338 been added. Portability fixes.
1339 * rrdcached plugin: This new plugin uses the (still in development)
1340 RRD accelerator daemon, rrdcached. This daemon works very similar to

1371 * Collectd::Unixsock: Error handling has been improved.
1372 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1373 patch.
1374 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1375 faults. Thanks to Peter Holik for his patch.
1376 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1377 code. Thanks to "thated" for reporting this.
1379 2009-01-02, Version 4.5.2
1380 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1381 file may be in both locations, especially when the database was
1382 installed in a non-standard path. Thanks to Dusty Doris for
1383 reporting this.
1384 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1385 Solaris, in the configure script automatically.
1386 * build system, tcpconns plugin: Check for `kvm_nlist' and
1387 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1388 library with similar functions to the BSD variant, but doesn't
1389 provide these necessary functions.
1390 * collectd.conf(5): Various fixes and clarifications.
1391 * collectd: Remove a GNUism (unnamed unions), thus improving
1392 portability.
1393 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1394 This solves portability problems, especially for Solaris.
1395 * dns plugin: Fix a portability problem with NetBSD.
1396 * filecount plugin: Fix an off-by-one error. This error may cause a
1397 segmentation fault.
1398 * network plugin: Fix the handling of `type' in the network protocol.
1399 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1400 much larger buffer. This caused the `type' to be transferred much
1401 more often than necessary. In some cases, e. g. the `cpu' and
1402 `cpufreq' plugins being used at the same time, data may be corrupted
1403 in those files. Thanks to Bruno Prémont for debugging and reporting
1404 this issue.
1405 * processes plugin: Fix a possible segmentation fault when specifying
1406 invalid configuration options.
1407 * unixsock plugin: Make sure the initialization function is run only
1408 once. This resolves a file descriptor leak under systems which run
1409 the initialization more than once, such as Solaris.
1411 2008-10-16, Version 4.5.1
1412 * build system: Change `--enable-<plugin>' to abort with an error if
1413 dependencies are not met. Thanks to Bruno Prémont for the patch.
1414 Also, the poisoning of various string functions has been restricted
1415 to debug builds.
1416 * collectd: Fix a memory leak in the global value cache. With every
1417 *missing* value a couple of bytes would be leaked. Another memory
1418 leak in the configuration handling code has been fixed. Thanks to
1419 Niraj Tolia for reporting these issues.
1420 * collectd: Fix an off-by-one error in the ignorelist functionality.
1421 When using regular expressions, the last character would be missing,
1422 possibly matching differently from what one would expect.
1423 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1424 problem.
1425 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1426 Linzberger for reporting the bug.
1427 * iptables plugin: Fix an off-by-one error. If a string was just one
1428 character too long, it was truncated instead of reporting an error.
1429 * network plugin: Fix a memory leak in the configuration handling
1430 code. Thanks to Niraj Tolia for reporting this issue.
1431 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1432 * postgresql plugin: Don't reopen connection during reinitialization.
1433 This fixes a bug under Solaris and potentially other platforms.
1434 Missing calls to `PQclear' have been added, too. This fixes memory
1435 leaks. Thanks to ``Admin'' for reporting these bugs.
1436 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1437 library.
1438 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1439 problems with some `libc's. Thanks to Matthias Lay for reporting the
1440 bug.
1442 2008-09-04, Version 4.5.0
1443 * collectd: Added the ability to flush certain identifiers.
1444 * collectd: The concept of `notification meta data' has been
1445 introduced.
1446 * filecount plugin: The new filecount plugin counts the number of
1447 files in a directory and its subdirectories.
1448 * ipmi plugin: Sensor names have been changed to ensure unique names.
1449 Notifications upon added and removed sensors can now be generated.
1450 * notify_desktop plugin: This new plugin sends notifications to the
1451 X desktop using the structure defined in the `Desktop Notification
1452 Specification'.
1453 * notify_email plugin: This new plugin sends out notifications via
1454 email, using the `esmtp' library.
1455 * onewire plugin: The new experimental(!) onewire plugin reads values,
1456 such as temperatures, from sensors connected to the computer via the
1457 onewire bus.
1458 * perl plugin: Improved synchronized access to internal data structures
1459 and fixed a possible dead-lock.
1460 * perl plugin: Added the ability to flush certain identifiers and marked
1461 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1462 plugin_flush().
1463 * perl plugin: Added the ability to configure Perl plugins.
1464 * postgresql plugin: The new postgresql plugin collects statistics
1465 about or from a PostgreSQL database.
1466 * processes plugin: The `ProcessMatch' option has been added.
1467 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1468 IO load.
1469 * tcpconns plugin: This plugin has been ported to OpenBSD.
1470 * thermal plugin: The new thermal plugin collects system temperatures
1471 using Linux ACPI thermal zone data.
1473 2009-01-02, Version 4.4.5
1474 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1475 file may be in both locations, especially when the database was
1476 installed in a non-standard path. Thanks to Dusty Doris for
1477 reporting this.
1478 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1479 Solaris, in the configure script automatically.
1480 * collectd.conf(5): Various fixes and clarifications.
1481 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1482 portability problems, especially for Solaris.
1483 * dns plugin: Fix a portability problem with NetBSD.
1484 * network plugin: Fix the handling of `type' in the network protocol.
1485 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1486 much larger buffer. This caused the `type' to be transferred much
1487 more often than necessary. In some cases, e. g. the `cpu' and
1488 `cpufreq' plugins being used at the same time, data may be corrupted
1489 in those files. Thanks to Bruno Prémont for debugging and reporting
1490 this issue.
1491 * unixsock plugin: Make sure the initialization function is run only
1492 once. This resolves a file descriptor leak under systems which run
1493 the initialization more than once, such as Solaris.
1495 2008-10-16, Version 4.4.4
1496 * build system: Change `--enable-<plugin>' to abort with an error if
1497 dependencies are not met. Thanks to Bruno Prémont for the patch.
1498 Also, the poisoning of various string functions has been restricted
1499 to debug builds.
1500 * collectd: Fix a memory leak in the global value cache. With every
1501 *missing* value a couple of bytes would be leaked. Another memory
1502 leak in the configuration handling code has been fixed. Thanks to
1503 Niraj Tolia for reporting these issues.
1504 * collectd: Fix an off-by-one error in the ignorelist functionality.
1505 When using regular expressions, the last character would be missing,
1506 possibly matching differently from what one would expect.
1507 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1508 problem.
1509 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1510 Linzberger for reporting the bug.
1511 * network plugin: Fix a memory leak in the configuration handling
1512 code. Thanks to Niraj Tolia for reporting this issue.
1513 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1514 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1515 problems with some `libc's. Thanks to Matthias Lay for reporting the
1516 bug.
1518 2008-09-01, Version 4.4.3
1519 * collectd: Fix a memory leak in the threshold checking code.
1520 * memcached plugin: Fix a too short timeout and a related file
1521 descriptor leak.
1522 * memory plugin: A typo in the libstatgrab code has been fixed.
1523 * snmp plugin: Fix a possible memory leak.
1525 2008-07-15, Version 4.4.2
1526 * build system: Use pkg-config to detect the upsclient library.
1527 * collectd: Try even harder to determine the endianess of the
1528 architecture collectd is being built on.
1529 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1530 of disks.
1531 * dns plugin: Fix compilation errors with BIND versions 19991001
1532 through 19991005.
1533 * network plugin: Bugfix in the init routine: The init function
1534 cleared a buffer regardless of its contents. This could lead to lost
1535 values under Solaris.
1536 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1537 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1538 function.
1539 * wireless plugin: Work around incorrect noise and power values
1540 returned by some broken drivers.
1542 2008-06-03, Version 4.4.1
1543 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1544 to kyrone for reporting this.
1545 * collectd: Fixed min/max output in notifications generated by
1546 threshold checking.
1547 * collectd-nagios: Fix the protocol used to communicate with the
1548 daemon.
1549 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1550 initialization has errors. An issue with Perl 5.10 has been fixed.
1551 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1552 René Rebe and Siegmund Gorr for reporting this.
1554 2008-05-06, Version 4.4.0
1555 * collectd: Internal code cleanups.
1556 * collectd: Added support for a `Flush' command in the unixsock and
1557 exec plugins. This command can be used to force a plugin (or all) to
1558 flush its values to disk.
1559 * collectd: Thresholds can now be configured to apply to one data
1560 source only, making it possible to configure different thresholds
1561 for each data source.
1562 * apache, nginx plugins: Added the possibility to disable host and/or
1563 peer verification.
1564 * ascent plugin: The new ascent plugin reads and parses the statistics
1565 page of an Ascent server.
1566 * cpu plugin: Support for the statgrab library has been added.
1567 * disk plugin: The possibility to ignore certain disks or collect only
1568 specific disks has been added.
1569 * disk plugin: Support for the statgrab library has been added.
1570 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1571 sensor values via IPMI, the intelligent platform management
1572 interface.
1573 * iptables plugin: The iptc library that is used by the iptables
1574 plugin has been added to the distribution, because it is not
1575 provided by all distributions and removed from at least one.
1576 * powerdns plugin: The new powerdns plugin reads statistics from an
1577 authoritative or a recursing PowerDNS name server.
1578 * rrdtool plugin: The size of the files generated with the default
1579 configuration has been decreased.

1581 continuously reading from log files.
1582 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1583 TeamSpeak2 server and collects statistics about the number of users
1584 and number of channels.
1585 * users plugin: Support for the statgrab library has been added.
1586 * vmem plugin: The new vmem plugin collects very detailed statistics
1587 about the virtual memory subsystem of Linux.
1589 2008-08-30, Version 4.3.4
1590 * Build system: Improved detection of and linking with the statgrab
1591 library.
1592 * collectd: Portability fixes, especially to determine endianess more
1593 reliable.
1594 * Various plugins: Fix format strings.
1595 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1596 again has been applied.
1597 * memcached plugin: Fix a too short timeout and a related file
1598 descriptor leak.
1599 * memory plugin: A typo in the libstatgrab code has been fixed.
1600 * network plugin: A fix in the initialization function solves problems
1601 under Solaris.
1602 * nginx plugin: A thread-unsafe function has been replaced.
1603 * vserver plugin: A thread-unsafe function has been replaced.

1605 added.
1607 2008-04-22, Version 4.3.3
1608 * build system: Improved detection of several libraries, especially if
1609 they are in non-standard paths.
1610 * build system: Portability fixes: Automatically define "_REENTRANT"
1611 if the libc expects it.
1612 * collectd: Error and warning messages have been improved.
1613 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1614 using them.
1615 * apache plugin: Allocate new memory when reading a webpage instead of
1616 using a buffer of static size.
1617 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1618 the program.
1619 * hddtemp plugin: Error and warning messages have been improved.
1620 * sensors plugin: Fix sensor collection for some chip types.
1622 2008-03-29, Version 4.3.2
1623 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1624 `Persist' threshold options.
1625 * collectd: Fix handling of missing values in the global value cache.
1626 * collectd: Improved error messages when parsing the configuration.
1627 * sensors plugin: Fix temperature collection with libsensors4.
1628 * unixsock plugin: Fix mixed input and output operation on streams.
1629 * wireless plugin: Fix reading noise value.
1631 2008-03-05, Version 4.3.1
1632 * exec plugin: Set supplementary group IDs.
1633 * network plugin:
1634 + Use `memcpy' when constructing/parsing a package to avoid
1635 alignment problems on weird architectures, such as Sparc.
1636 + Translate doubles to/from the x86 byte representation to ensure
1637 cross-platform compatibility.
1638 * ping plugin: Correct the handling of the `TTL' setting.
1639 * swap plugin: Reapply a patch for Solaris.
1640 * tcpconns plugin: Portability improvements.
1642 2008-02-18, Version 4.3.0
1643 * collectd: Notifications have been added to the daemon. Notifications
1644 are status messages that may be associated with a data instance.
1645 * collectd: Threshold checking has been added to the daemon. This
1646 means that you can configure threshold values for each data
1647 instance. If this threshold is exceeded a notification will be
1648 created.
1649 * collectd: The new `FQDNLookup' option tells the daemon to use the
1650 full qualified domain name as the hostname, not just the host part
1651 es returned by `gethostname(2)'.
1652 * collectd: Support for more than one `TypesDB' file has been added.
1653 This is useful when one such file is included in a package but one
1654 wants to add custom type definitions.
1655 * collectd: The `Include' config option has been expanded to handle
1656 entire directories and shell wildcards.
1657 * collectdmon: The new `collectdmon' binary detects when collectd
1658 terminates and automatically restarts it again.
1659 * csv plugin: The CSV plugin is now able to store counter values as a
1660 rate, using the `StoreRates' configuration option.
1661 * exec plugin: Handling of notifications has been added and the
1662 ability to pass arguments to the executed programs has been added.
1663 * hddtemp plugin: The new `TranslateDevicename' option lets you
1664 disable the translation from device names to major-minor-numbers.
1665 * logfile plugin: Handling of notifications has been added.
1666 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1667 domain name lookups in this plugin.
1668 * perl plugin: Many internal changes added support for handling multiple
1669 threads making the plugin reasonably usable inside collectd. The API has
1670 been extended to support notifications and export global variables to
1671 Perl plugins; callbacks now have to be identified by name rather than a
1672 pointer to a subroutine. The plugin is no longer experimental.
1673 * uuid plugin: The new UUID plugin sets the hostname to an unique
1674 identifier for this host. This is meant for setups where each client
1675 may migrate to another physical host, possibly going through one or
1676 more name changes in the process. Thanks to Richard Jones from
1677 Red Hat's Emerging Technology group for this plugin.
1678 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1679 CPU, disk and network statistics about guest systems on the same
1680 physical server. Thanks to Richard Jones from Red Hat's Emerging
1681 Technology group for this plugin.
1683 2008-04-22, Version 4.2.7
1684 * build system: Improved detection of several libraries, especially if
1685 they are in non-standard paths.
1686 * build system: Portability fixes: Automatically define "_REENTRANT"
1687 if the libc expects it.
1688 * collectd: Error and warning messages have been improved.
1689 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1690 using them.
1691 * apache plugin: Allocate new memory when reading a webpage instead of
1692 using a buffer of static size.
1693 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1694 the program.
1695 * hddtemp plugin: Error and warning messages have been improved.
1696 * sensors plugin: Fix sensor collection for some chip types.
1698 2008-03-29, Version 4.2.6
1699 * collectd: Improved error messages when parsing the configuration.
1700 * sensors plugin: Fix temperature collection with libsensors4.
1701 * unixsock plugin: Fix mixed input and output operation on streams.
1702 * wireless plugin: Fix reading noise value.
1704 2008-03-04, Version 4.2.5
1705 * apache plugin: Improved initialization and error messages.
1706 * exec plugin: Set supplementary group IDs.
1707 * network plugin:
1708 + Create separate threads for reading from the socket and parsing
1709 and dispatching incoming packets. Versions prior to this may have
1710 problems in high-load situations, where the socket receive buffers
1711 overflows, resulting in gaps in the data.
1712 + Use `memcpy' when constructing/parsing a package to avoid
1713 alignment problems on weird architectures, such as Sparc.
1714 + Translate doubles to/from the x86 byte representation to ensure
1715 cross-platform compatibility.
1716 * ping plugin: Correct the handling of the `TTL' setting.
1717 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1718 * swap plugin: Reapply a patch for Solaris.
1719 * tcpconns plugin: Portability improvements.
1721 2008-01-21, Version 4.2.4
1722 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1723 the permission on the socket as documented in the manpage. Thanks to
1724 Evgeny Chukreev for fixing this issue.
1725 * collectd: The documentation has been improved.
1727 2007-12-28, Version 4.2.3
1728 * sensors plugin: Updated the plugin to build and work with version 3
1729 of the libsensors library.
1731 2007-12-15, Version 4.2.2
1732 * nginx plugin: Incorrect comparison of strings lead to a segfault
1733 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1734 this.
1735 * logfile plugin: The config option `Timestamp' was handled
1736 incorrectly and basically always active. Thanks to Luke Heberling
1737 for fixing this.
1739 2007-11-08, Version 4.2.1
1740 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1741 enabled on the host.
1742 * snmp plugin: Fix a memory leak.
1744 2007-10-27, Version 4.2.0
1745 * collectd: The new config option `Include' lets you include other
1746 configfiles and thus split up your config into smaller parts. This
1747 may be especially interesting for the snmp plugin to keep the data
1748 definitions separate from the host definitions.
1749 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1750 (number of connections, octets and packets for each service and
1751 destination). Thanks to Sebastian Harl for this plugin.
1752 * memcached plugin: The new `memcached' plugin connects to a memcached
1753 daemon process and collects statistics of this distributed caching
1754 system. Thanks to Antony Dovgal for contributing this plugin.
1755 * nginx plugin: The new `nginx' plugin reads the status page of an
1756 nginx daemon and saves the handled connections and requests.
1757 * perl plugin: Many changes, including the added `EnableDebugger'
1758 config option which lets you debug your Perl plugins more easily.
1759 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1760 be more thread-safe otherwise by locking calls to the library.
1761 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1762 correct the values returned by SNMP-agents. If a <data> block is
1763 defined as `table' the instance is now optional. The sequence number
1764 is used as the type-instance in this case. The new `InstancePrefix'
1765 option allows to add arbitrary prefixes to the type-instance.
1766 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1767 certain TCP connections and what state they're in. This can be used
1768 to see how many connections your FTP server has to handle or how
1769 many outgoing connections your mailserver has open.
1771 2008-01-11, Version 4.1.6
1772 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1773 the permission on the socket as documented in the manpage. Thanks to
1774 Evgeny Chukreev for fixing this issue.
1775 * collectd: The documentation has been improved.
1777 2007-12-27, Version 4.1.5
1778 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1779 memory situations.
1780 * sensors plugin: Updated the plugin to build and work with version 3
1781 of the libsensors library.
1783 2007-11-08, Version 4.1.4
1784 * Build system: Improve detection of the rrd library, especially if
1785 it's in a non-standard location.
1786 * Build system: A bug when parsing the argument for
1787 `--with-libnetsnmp' has been fixed.
1788 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1789 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1790 a deadlock or delay when shutting down the daemon.
1791 * snmp plugin: Fix a memory leak.
1793 2007-10-24, Version 4.1.3
1794 * collectd: A build issue under Solaris has been resolved by renaming
1795 data types.
1796 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1797 be more thread-safe otherwise by locking calls to the library.
1799 2007-09-28, Version 4.1.2
1800 * apcups plugin: Fix reporting of the `load percent' data.
1801 * wireless plugin: Correct the handling of cards returning signal and
1802 noise quality as percentage.
1803 * perl plugin: Fix a possible buffer overflow in get_module_name().
1804 * build system: Further improve the detection of libraries.
1805 * netlink plugin: Build issues under some older versions of the Linux
1806 includes (i. e. Debian Sarge) have been fixed.
1807 * snmp plugin: Fix a potential segfault when a host times out. Add
1808 support for the `timeticks' type.
1810 2007-09-12, Version 4.1.1
1811 * Build system: The detection of `libnetlink' has been improved.
1812 * collectd: The documentation has been fixed in numerous places.
1813 * exec plugin: Setting the group under which to run a program has been
1814 fixed.
1815 * collectd: The `sstrerror' function was improved to work correctly
1816 with the broken GNU version of `strerror_r'.
1817 * collectd: Write an error message to STDERR when loading of a plugin
1818 fails.
1819 * apcups plugin: Fix the `types' used to submit the values: They still
1820 has an `apcups_' prefix which doesn't work anymore.
1821 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1822 whatever the client thinks is `now'..
1824 2007-09-01, Version 4.1.0
1825 * Build system: The build system has been changed to automatically
1826 disable all plugins, which are missing dependencies. The dependency
1827 checking has been removed from the plugins themselves to remove
1828 redundancy.
1829 * Flexible interval: The interval of collected data is now sent along
1830 with the data itself over the network, so that the interval-settings
1831 of server and clients no longer needs to match.
1832 * netlink plugin: The new `netlink' plugin connects to the Linux
1833 kernel using a netlink socket and uses it to query information about
1834 interfaces, qdiscs and classes.
1835 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1836 to not block data collection.
1837 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1838 network devices, such as switches, routers, thermometers, rack
1839 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1840 plugin.
1841 * unixsock plugin: Added the `LISTVAL' command.
1842 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1843 of music played with xmms.
1845 2007-09-28, Version 4.0.9
1846 * apcups plugin: Fix reporting of the `load percent' data.
1847 * wireless plugin: Correct the handling of cards returning signal and
1848 noise quality as percentage.
1849 * perl plugin: Fix a possible buffer overflow in get_module_name().
1851 2007-09-12, Version 4.0.8
1852 * collectd: The `sstrerror' function was improved to work correctly
1853 with the broken GNU version of `strerror_r'.
1854 * collectd: Write an error message to STDERR when loading of a plugin
1855 fails.
1856 * apcups plugin: Fix the `types' used to submit the values: They still
1857 has an `apcups_' prefix which doesn't work anymore.
1858 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1859 whatever the client thinks is `now'..
1861 2007-08-26, Version 4.0.7
1862 * documentation: Some typos have been fixed and some information has
1863 been improved.
1864 * build system: Many fixes for detecting libraries in unusual places,
1865 such as on RedHat systems. The affected libraries are `libcurl',
1866 `libmysql', and `libupsclient'.
1867 * network plugin: Allow the `Port' option to be specified as a number
1868 (i. e. without quotes).
1869 * nut plugin: A fix allows linking the nut plugin against
1870 libupsclient, version >= 2.2.0.
1871 * processes plugin: Fix a potential segmentation fault.
1873 2007-07-30, Version 4.0.6
1874 * sensors plugin: Fix the ignorelist functionality: Only the `type
1875 instance' was used to match against the list, but the documentation
1876 told otherwise. This release fixes the code, so it complies with the
1877 documentation.
1878 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1879 configuration messages will end up in the logging facility.
1880 * conrtib/fedora: The contributed specfile for Fedora has been
1881 updated.
1883 2007-07-05, Version 4.0.5
1884 * Portability: More fixes for OpenBSD have been included.
1886 2007-06-24, Version 4.0.4
1887 * cpu plugin: Fixed the Solaris code.
1888 * dns plugin: Fixed a build issue for OpenBSD.
1889 * interface plugin: Fixed the Solaris code.
1890 * load plugin: Fixed the alternative `/proc' Linux code.
1891 * memory plugin: Fixed the Solaris code.
1892 * oconfig: Don't require `-lfl' anymore.
1894 2007-06-19, Version 4.0.3
1895 * cpu plugin: Fix the Darwin / Mac OS X code.
1896 * ping plugin: Use the return value of `getpid', not its address.
1897 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1898 initialized correctly.
1899 * configure: Added `--with-nan-emulation' to aid cross compilation.
1901 2007-06-12, Version 4.0.2
1902 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1903 they're given in numerically form.
1905 2007-06-07, Version 4.0.1
1906 * iptables plugin: A bug in the configuration routine has been fixed.
1907 Setting a comment in the configfile will no longer cause a
1908 segmentation fault.
1910 2007-06-03, Version 4.0.0
1911 * collectd: The plugin-infrastructure has been changed to allow for
1912 more types of plugins, namely `write' and `log' plugins.
1913 * collectd: The read-function has been changed to read many plugins in
1914 parallel, using threads. Thus, plugins generally need to use
1915 thread-safe functions from now on.
1916 * collectd: The '-t' command line options allows to perform syntax tests
1917 of the configuration file and exit immediately.
1918 * csv plugin: The new `csv' plugin handles output to `comma separated
1919 values'-files.
1920 * rrdtool plugin: The new `rrdtool' plugin handles output to
1921 RRD-files. Data can be cached to combine multiple updates into one
1922 write to increase IO-performance.
1923 * network plugin: The new `network' plugin handles IO via the network.
1924 It implements a different, much more extensible protocol which can
1925 combine many values in one packet, decreasing the number of UDP-
1926 packets being sent. It can read from and send to the network and
1927 with the appropriate configuration even forward packets to other
1928 networks.
1929 * unixsock plugin: The new `unixsock' plugin provides an interface to
1930 communicate with the daemon while it is running. Right now the
1931 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1932 come.
1933 * perl plugin: The new `perl' plugin allows you to write extensions
1934 for collectd in the scripting-language Perl.
1935 * logfile plugin: The new `logfile' plugin writes logmessages to files
1936 or STDOUT or STDERR.
1937 * syslog plugin: The new `syslog' plugin sends logmessages to the
1938 system's syslog daemon.
1939 * entropy plugin: The new `entropy' plugin collects the amount of
1940 entropy currently being available to the system.
1941 * exec plugin: The new `exec' plugin forks child processes and reads
1942 back values provided by the forked processes.
1943 * iptables plugin: The new `iptables' plugin reads counters from
1944 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1945 plugin.
1946 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1947 to Peter Holik for contributing this plugin.
1948 * nut plugin: The new `nut' plugin connects the upsd of the `network
1949 ups tools' and reads information about the connected UPS.
1950 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1951 connections) field was added by Florent Monbillard.
1952 * collectd-nagios: The new `collectd-nagios' binary queries values
1953 from collectd, parses them and exits according to Nagios-standards.
1954 * manpages: The manpages have been improved a lot.
1956 2007-09-28, Version 3.11.7
1957 * wireless plugin: Correct the handling of cards returning signal and
1958 noise quality as percentage.
1960 2007-08-31, Version 3.11.6
1961 * processes plugin: Fix a potential segmentation fault.
1963 2007-05-29, Version 3.11.5
1964 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1965 * ntpd plugin: Fix a potential buffer overflow.
1966 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1967 were accounted as `zombies'.
1969 2007-04-10, Version 3.11.4
1970 * dns plugin: Change the order of includes to make the plugin compile
1971 under FreeBSD.
1973 2007-03-30, Version 3.11.3
1974 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1975 of the unused `COLLECT_KSTAT'.
1977 2007-02-11, Version 3.11.2
1978 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1979 NULL-pointer may have been passed to `printf' which causes a
1980 segfault with some libcs.
1982 2007-02-10, Version 3.11.1
1983 * df plugin: Some wrong defines have been fixed so the plugin works
1984 under Solaris again.
1985 * dns plugin: The usage of a struct has been fixed to work with
1986 non-GNU libcs.
1987 * processes plugin: Some missing defines have been added so the plugin
1988 compiles cleanly under FreeBSD and presumably other UNIXes.
1990 2006-12-22, Version 3.11.0
1991 * collectd: The new command line option `-P' makes it easier for
1992 distributors to change the location of PID-files.
1993 * collectd: The daemon shuts down faster now which makes it easier to
1994 write init.d-scripts for it.
1995 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1996 caused problems every now and then.
1997 * df plugin: New config options allow to ignore certain mountpoints,
1998 filesystem types or devices.
1999 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2000 and interprets it. It collects traffic as well as qtype, opcode and
2001 rcode counts.
2002 * email plugin: Sebastian Harl has contributed this plugin which
2003 counts received mails in categories (e. g. ham, spam, virus), spam
2004 score (as given by SpamAssassin) and check types.
2005 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2006 uses `mbmon' to gather information from sensors on the motherboard.
2007 * processes plugin: Collect detailed statistics for configured
2008 processes, that's process and thread count, CPU usage, resident
2009 segment size and pagefaults.
2010 * multimeter plugin: Peter Holik contributed a new plugin which
2011 queries multimeters.
2012 * sensors plugin: Lubos Stanek has put much effort into improving this
2013 plugin, including `extended naming', collection of voltage values
2014 and the possibility to ignore certain values.
2016 2006-12-21, Version 3.10.4
2017 * Max Kellermann has identified a bug in the server routine: When
2018 opening a socket fails the daemon will (re)try opening the socket in
2019 an endless loop, ultimately leading to a `EMFILE' error.
2021 2006-11-04, Version 3.10.3
2022 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2023 ntpd's reply was sent in more than one packet, the buffer size was
2024 calculated incorrectly, resulting in the reading of uninitialized or
2025 freed memory.
2027 2006-11-01, Version 3.10.2
2028 * The sample config file has been improved.
2029 * Errors in the manpages have been corrected.
2030 * The ping-plugin now adds hosts during initialization, not during
2031 startup. This speeds up startup when no network connectivity is
2032 available. Also, the hosts are being added later when the network is
2033 available.
2034 * Improved BSD-support for the df-plugin.
2035 * Fixed syntax errors in the swap-plugin for Mac OS X.
2036 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2037 plugin.
2038 * Don't disable the mysql-plugin if connecting to the database fails
2039 during initialization. Instead, try again in increasing intervals.
2041 2006-07-19, Version 3.10.1
2042 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2043 the apcups cannot be reached, unconnected sockets will pile up and
2044 eventually lead to `Too many open files' errors.
2046 2006-07-09, Version 3.10.0
2047 * The `disk' plugin has been ported to Darwin.
2048 * The `battery' plugin should work on many Apple computers now.
2049 * The `traffic' plugin can now ignore certain interfaces. Also,
2050 statistics for sent/received packets and errors have been added.
2051 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2052 to Anthony Gialluca for contributing this plugin and providing me
2053 with a test environment :)
2054 * A plugin for monitoring an NTP instance and the local clock drift
2055 has been added.
2057 2006-06-25, Version 3.9.4
2058 * The Solaris code in the `swap' plugin has been changed to reflect
2059 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2060 working this out.
2061 * The debugging system has been fixed to work with the Sun libc.
2062 * When built without librrd the variable `operating_mode' could be
2063 uninitialized. Thanks to David Elliot for reporting the bug.
2065 2006-06-01, Version 3.9.3
2066 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2067 operating systems also profit from the changes, but I wasn't able to
2068 check that.
2069 * Changed the build system to find the netinet-includes under FreeBSD
2070 and therefore successfully build the `liboping' library there.
2072 2006-05-09, Version 3.9.2
2073 * Applied a patch to the `liboping' library. Due to a bug in the
2074 sequence checking the `ping' plugin stopped working after
2075 approximately 7.6 days.
2077 2006-05-09, Version 3.8.5
2078 * Applied a patch to the `liboping' library. Due to a bug in the
2079 sequence checking the `ping' plugin stopped working after
2080 approximately 7.6 days.
2082 2006-04-21, Version 3.9.1
2083 * Build issues with Solaris and possible other architectures have been
2084 resolved.
2085 * Problems when building the `apache'-plugin without `libcurl' have
2086 been resolved.
2087 * A bug in the `ping' plugin has been fixed. Sorry folks.
2089 2006-04-02, Version 3.9.0
2090 * A plugin to monitor the Apache webserver has been added.
2091 <http://httpd.apache.org/>
2092 * A plugin to collect statistics about virtual servers using VServer.
2093 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2094 this plugin :)
2095 * A plugin for wireless LAN cards has been added. It monitors signal
2096 strength, link quality and noise ratio..
2097 * A plugin for Apple hardware sensors has been added.
2098 * An option to compile collectd with different `step' and `heartbeat'
2099 settings has been added. The size of RRAs is no longer static but
2100 calculated based on the settings for `step' and `width'.
2101 * The `ping' plugin can now be configured to use a certain TTL.
2102 * A plugin to monitor the hardware sensors of Apple computers has been
2103 added.
2104 * The plugins `cpu', `memory', `processes' and `traffic' have been
2105 ported to Mach/Darwin (Mac OS X).
2106 * The `log mode' has been contributed by Christophe Kalt. It writes
2107 the data into text files rather than RRD files.
2109 2006-04-09, Version 3.8.4
2110 * Applied patch by Vincent Stehlé which improves the disk-name
2111 resolution in the `hddtemp' plugin for Linux systems.
2113 2006-04-02, Version 3.8.3
2114 * Applied a patch by James Byers: The MySQL plugin was not working
2115 with MySQL 5.0.2 or later.
2117 2006-03-14, Version 3.8.2
2118 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2119 the GNU libc, because it points to `/etc/fstab' rather than
2120 `/etc/mtab'.
2122 2006-03-13, Version 3.8.1
2123 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2124 * Fixes in the debian `postinst' and `init.d' scripts.
2126 2006-03-09, Version 3.8.0
2127 * The `ping' plugin no longer uses `libping' but a self written
2128 library named `liboping'. With this library it's possible to ping
2129 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2131 2006-02-18, Version 3.7.2
2132 * A simple bug in the `battery' plugin has been fixed. It should now
2133 work with ACPI based batteries as well. Thanks to Sebastian for
2134 fixing this.
2135 * Fixing a bug that prevented collectd to be built without librrd.
2136 Thanks to Werner Heuser for reporting it.
2138 2006-02-04, Version 3.7.1
2139 * The new network code has been improved to build with older versions
2140 of glibc.
2141 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2142 to Tommie Gannert for this patch.
2144 2006-01-30, Version 3.7.0
2145 * The `battery' plugin has been added. It collects information about
2146 laptop batteries..
2147 * The MySQL plugin has been improved: It now writes two more RRD
2148 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2149 * The `cpufreq' plugin now reads another file since the file it did
2150 read so far causes much overhead in the kernel. Also, you need root
2151 to read the old file, but not to read the new one.
2152 * The `hddtemp' plugin can now be configured to connect to another
2153 address and/or port than localhost.
2154 * The `df' plugin now prefers `statvfs' over `statfs'.
2155 * The network code has been rewritten. collectd now supports unicast
2156 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2157 be set in the configfile.
2159 2006-01-24, Version 3.6.2
2160 * Due to a bug in the configfile handling collectd wouldn't start in
2161 client mode. This released fixes this.
2163 2006-01-20, Version 3.6.1
2164 * Due to a bug in `configure.in' all modules and the binary were
2165 linked against `libmysqlclient'. This issue is solved by this
2166 release.
2168 2006-01-17, Version 3.6.0
2169 * A config file has been added. This allows for loading only specific
2170 plugins.
2171 * A `df' plugin has been added.
2172 * A `mysql' plugin has been added.
2173 * The `ping' plugin doesn't entirely give up hope when a socket error
2174 occurred, but will back of and increase the intervals between tries.
2176 2006-01-21, Version 3.5.2
2177 * Fixed yet another bug in the signal handling.. Stupid typo..
2178 * Improved the ping plugin to not give up on socket errors (backport
2179 from 3.6.0).
2181 2005-12-18, Version 3.5.1
2182 * The PID-file is now deleted correctly when shutting down the daemon.
2183 * SIGINT and SIGTERM are now handled correctly.
2185 2005-12-16, Version 3.5.0 (Revision 326)
2186 * A bug in the `load' module under Solaris has been fixed.
2187 * The `users' module has been contributed by Sebastian Harl. It counts
2188 currently logged in users.
2189 * The CPU module now works under FreeBSD without the use of
2190 `libstatgrab', however SMP support is missing.
2191 * The default directories for the RRD files and the PID file now
2192 depend on the compile time setting of `localstatedir'.
2194 2005-11-15, Version 3.4.0 (Revision 236)
2195 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2196 from gentoo's bugzilla for writing the patch.
2197 * The build dependency for librrd has been removed. Binaries built
2198 without librrd are client-only and will multicast their value as
2199 with the `-c' argument.
2200 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2201 * The newly introduced `-f' switch prevents daemon initialization
2202 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2203 Barcellos for this patch.
2205 2005-11-04, Version 3.3.0 (Revision 216)
2206 * New modules have been added:
2207 - `serial', for monitoring traffic on the serial interfaces
2208 - `nfs', for graphing NFS procedure calls
2209 - `tape', traffic from/to tape devices
2210 * The memory.rrd now accepts more than 4Gig of memory.
2212 2005-10-26, Version 3.2.0 (Revision 200)
2213 * Support for graphing the processes has been added (thanks to Lyonel
2214 Vincent)
2215 * If reading from hddtemp fails collectd will increase the time
2216 between polls up to one day.
2217 * The init.d files have been improved.
2218 * Problems with the spec file have been fixed.
2220 2005-10-16, Version 3.1.0 (Revision 194)
2221 * Added the `setsid' syscall to the startup code.
2222 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2224 2005-09-30, Version 3.0.0 (Revision 184)
2225 * The ability to send/receive data to/from the network (think
2226 multicast) has been added.
2227 * Modules have been split up into shared libraries can be loaded at
2228 runtime. The biggest advantage is that the core program doesn't need
2229 to be linked against an external library.
2230 * A patch by George Kargiotakis has been applied: It fixes the sensors
2231 behaviour then more than one sensor is being queried.
2233 2005-09-16, Version 2.1.0 (Revision 172)
2234 * A module for swap statistics has been added.
2236 2005-09-09, Version 2.0.0 (Revision 135)
2237 * Filenames can no longer be configured at program startup. The only
2238 options as of this version are the directory and ping hosts.
2239 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2240 Soft-IRQ statistics are added to `System'.
2241 * Diskstats now collect read and write bytes, not sectors.
2242 * Ping statistics can now be collected for more than one host. There
2243 is no default any more: If no host is given no host will be pinged.
2244 * A self-written patch for libping has been applied so it builds
2245 cleanly.
2247 2005-09-01, Version 1.8.1 (Revision 123)
2248 * Much improved configure-script: libraries and features may now be
2249 disabled.
2250 * More detailed warnings/error messages when RRD update fails.
2252 2005-08-29, Version 1.8.0:
2253 * Support for collecting disk statistics under Solaris.
2255 2005-08-25, Version 1.7.0:
2256 * Support for libstatgrab[1] for load, memory usage and network
2257 traffic. CPU- and disk-usage are not (yet) supported, since
2258 libstatgrab returns insufficient information. I will contact the
2259 authors.
2260 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2261 aren't necessarily counted linear which is now handled correctly.
2262 [1]: http://www.i-scream.org/libstatgrab/
2264 2005-08-21, Version 1.6.0:
2265 * Basic support for Solaris: System load and cpu-usage can be
2266 collected under Solaris, too. Other stats will follow later.
2267 * Many fixes in the autoconf-script
2268 * Collection/Museum scripts have been added under contrib/museum
2269 * collectd may now be started in unprivileged mode, though ping
2270 statistics will not work.
2272 2005-07-17, Version 1.5.1:
2273 * Diskstats-RRDs now use major/minor for naming. Some systems have
2274 weird strings as disk-names..
2276 2005-07-17, Version 1.5:
2277 * A new module, diskstats, has been added. It collects information
2278 about the disks and partitions.
2280 2005-07-11, Version 1.4.2:
