617 bug.
618 * snmp plugin: A bug when casting unsigned integers to gauge values has
619 been fixed: Unsigned integers would be cast to a signed integer and
620 then to a gauge, possibly resulting in a negative value.

1293 Bruno Prémont for finding this problem.
1294 * bind plugin: Fix collection of the cached RR sets. The number of RR
1295 sets currently in the cache was collected as a counter value, which

1342 MacEachern for the patch.
1343 * curl plugin: This new plugin can be used to read web pages and parse
1344 them using the same mechanism that's used in the tail plugin.
1345 * dbi plugin: This new plugin allows you to connect to a variety of
1346 relational databases and use SQL to gather custom statistics from
1347 it. It is similar to the already existing PostgreSQL plugin but uses
1348 libdbi to communicate with the database(s).
1349 * interface plugin: Use the ignorelist framework when selecting /
1350 ignoring interfaces. This allows one to use regular expressions to
1351 select interfaces, too.

1366 have been added.
1367 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1368 * perl plugin: Added support for `notification meta data'.
1369 * perl plugin: Added support for the `filter chain' infrastructure by
1370 allowing plugins to register `matches' and `targets'.
1371 * postgresql plugin: The preferred configuration syntax has been
1372 updated to be in line with the syntax used by the new dbi and oracle
1373 plugins. The compatibility code for the old syntax is present.
1374 Support for the new `Result' blocks and the interval parameter has
1375 been added.
1376 * processes plugin: Stacksize and virtual memory usage statistics have
1377 been added. Portability fixes.
1378 * rrdcached plugin: This new plugin uses the (still in development)
1379 RRD accelerator daemon, rrdcached. This daemon works very similar to
1380 the original rrdtool plugin of collectd, but adds some more nice
1381 features.
1382 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1383 added.
1385 2009-05-09, Version 4.5.4
1386 * Build system, various plugins: Many build fixes for FreeBSD,
1387 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1388 for many fixes and providing a build system for many platforms,
1389 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1390 providing an OpenBSD system.
1391 * collectd: Fix a potential race condition when creating directories.
1392 * battery plugin: Don't complain about a missing directory every
1393 interval.
1394 * dns plugin: Slight portability fixes.
1395 * exec plugin: Allow executed programs to close STDERR. Thanks to
1396 Thorsten von Eicken for reporting this problem.
1397 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1398 Tomasz Pala for the patch.
1399 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1400 the patch.
1401 * rrdtool plugin: Fix a possible race condition: If the network plugin
1402 is initialized and dispatches a value before the rrdtool plugin is
1403 initialized, the daemon may crash.
1404 * memory plugin: Fix a potential problem under Solaris.
1406 2009-02-22, Version 4.5.3
1407 * build system: The check for libupsclient even when `pkg-config' is
1408 not available.
1409 * collectd: Fix error handling in the global cache.
1410 * Collectd::Unixsock: Error handling has been improved.
1411 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1412 patch.
1413 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1414 faults. Thanks to Peter Holik for his patch.
1415 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1416 code. Thanks to "thated" for reporting this.
1418 2009-01-02, Version 4.5.2
1419 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1420 file may be in both locations, especially when the database was
1421 installed in a non-standard path. Thanks to Dusty Doris for
1422 reporting this.
1423 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1424 Solaris, in the configure script automatically.
1425 * build system, tcpconns plugin: Check for `kvm_nlist' and
1426 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1427 library with similar functions to the BSD variant, but doesn't
1428 provide these necessary functions.
1429 * collectd.conf(5): Various fixes and clarifications.
1430 * collectd: Remove a GNUism (unnamed unions), thus improving
1431 portability.
1432 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1433 This solves portability problems, especially for Solaris.
1434 * dns plugin: Fix a portability problem with NetBSD.
1435 * filecount plugin: Fix an off-by-one error. This error may cause a
1436 segmentation fault.
1437 * network plugin: Fix the handling of `type' in the network protocol.
1438 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1439 much larger buffer. This caused the `type' to be transferred much
1440 more often than necessary. In some cases, e. g. the `cpu' and
1441 `cpufreq' plugins being used at the same time, data may be corrupted
1442 in those files. Thanks to Bruno Prémont for debugging and reporting
1443 this issue.
1444 * processes plugin: Fix a possible segmentation fault when specifying
1445 invalid configuration options.
1446 * unixsock plugin: Make sure the initialization function is run only
1447 once. This resolves a file descriptor leak under systems which run
1448 the initialization more than once, such as Solaris.
1450 2008-10-16, Version 4.5.1
1451 * build system: Change `--enable-<plugin>' to abort with an error if
1452 dependencies are not met. Thanks to Bruno Prémont for the patch.
1453 Also, the poisoning of various string functions has been restricted
1454 to debug builds.
1455 * collectd: Fix a memory leak in the global value cache. With every
1456 *missing* value a couple of bytes would be leaked. Another memory
1457 leak in the configuration handling code has been fixed. Thanks to
1458 Niraj Tolia for reporting these issues.
1459 * collectd: Fix an off-by-one error in the ignorelist functionality.
1460 When using regular expressions, the last character would be missing,
1461 possibly matching differently from what one would expect.
1462 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1463 problem.
1464 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1465 Linzberger for reporting the bug.
1466 * iptables plugin: Fix an off-by-one error. If a string was just one
1467 character too long, it was truncated instead of reporting an error.
1468 * network plugin: Fix a memory leak in the configuration handling
1469 code. Thanks to Niraj Tolia for reporting this issue.
1470 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1471 * postgresql plugin: Don't reopen connection during reinitialization.
1472 This fixes a bug under Solaris and potentially other platforms.
1473 Missing calls to `PQclear' have been added, too. This fixes memory
1474 leaks. Thanks to ``Admin'' for reporting these bugs.
1475 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1476 library.
1477 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1478 problems with some `libc's. Thanks to Matthias Lay for reporting the
1479 bug.
1481 2008-09-04, Version 4.5.0
1482 * collectd: Added the ability to flush certain identifiers.
1483 * collectd: The concept of `notification meta data' has been
1484 introduced.
1485 * filecount plugin: The new filecount plugin counts the number of
1486 files in a directory and its subdirectories.
1487 * ipmi plugin: Sensor names have been changed to ensure unique names.
1488 Notifications upon added and removed sensors can now be generated.
1489 * notify_desktop plugin: This new plugin sends notifications to the
1490 X desktop using the structure defined in the `Desktop Notification
1491 Specification'.
1492 * notify_email plugin: This new plugin sends out notifications via
1493 email, using the `esmtp' library.
1494 * onewire plugin: The new experimental(!) onewire plugin reads values,
1495 such as temperatures, from sensors connected to the computer via the
1496 onewire bus.
1497 * perl plugin: Improved synchronized access to internal data structures
1498 and fixed a possible dead-lock.
1499 * perl plugin: Added the ability to flush certain identifiers and marked
1500 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1501 plugin_flush().
1502 * perl plugin: Added the ability to configure Perl plugins.
1503 * postgresql plugin: The new postgresql plugin collects statistics
1504 about or from a PostgreSQL database.
1505 * processes plugin: The `ProcessMatch' option has been added.
1506 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1507 IO load.
1508 * tcpconns plugin: This plugin has been ported to OpenBSD.
1509 * thermal plugin: The new thermal plugin collects system temperatures
1510 using Linux ACPI thermal zone data.
1512 2009-01-02, Version 4.4.5
1513 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1514 file may be in both locations, especially when the database was
1515 installed in a non-standard path. Thanks to Dusty Doris for
1516 reporting this.
1517 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1518 Solaris, in the configure script automatically.
1519 * collectd.conf(5): Various fixes and clarifications.
1520 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1521 portability problems, especially for Solaris.
1522 * dns plugin: Fix a portability problem with NetBSD.
1523 * network plugin: Fix the handling of `type' in the network protocol.
1524 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1525 much larger buffer. This caused the `type' to be transferred much
1526 more often than necessary. In some cases, e. g. the `cpu' and
1527 `cpufreq' plugins being used at the same time, data may be corrupted
1528 in those files. Thanks to Bruno Prémont for debugging and reporting
1529 this issue.
1530 * unixsock plugin: Make sure the initialization function is run only
1531 once. This resolves a file descriptor leak under systems which run
1532 the initialization more than once, such as Solaris.
1534 2008-10-16, Version 4.4.4
1535 * build system: Change `--enable-<plugin>' to abort with an error if
1536 dependencies are not met. Thanks to Bruno Prémont for the patch.
1537 Also, the poisoning of various string functions has been restricted
1538 to debug builds.
1539 * collectd: Fix a memory leak in the global value cache. With every
1540 *missing* value a couple of bytes would be leaked. Another memory
1541 leak in the configuration handling code has been fixed. Thanks to
1542 Niraj Tolia for reporting these issues.
1543 * collectd: Fix an off-by-one error in the ignorelist functionality.
1544 When using regular expressions, the last character would be missing,
1545 possibly matching differently from what one would expect.
1546 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1547 problem.
1548 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1549 Linzberger for reporting the bug.
1550 * network plugin: Fix a memory leak in the configuration handling
1551 code. Thanks to Niraj Tolia for reporting this issue.
1552 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1553 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1554 problems with some `libc's. Thanks to Matthias Lay for reporting the
1555 bug.
1557 2008-09-01, Version 4.4.3
1558 * collectd: Fix a memory leak in the threshold checking code.
1559 * memcached plugin: Fix a too short timeout and a related file
1560 descriptor leak.
1561 * memory plugin: A typo in the libstatgrab code has been fixed.
1562 * snmp plugin: Fix a possible memory leak.
1564 2008-07-15, Version 4.4.2
1565 * build system: Use pkg-config to detect the upsclient library.
1566 * collectd: Try even harder to determine the endianess of the
1567 architecture collectd is being built on.
1568 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1569 of disks.
1570 * dns plugin: Fix compilation errors with BIND versions 19991001
1571 through 19991005.
1572 * network plugin: Bugfix in the init routine: The init function
1573 cleared a buffer regardless of its contents. This could lead to lost
1574 values under Solaris.
1575 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1576 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1577 function.
1578 * wireless plugin: Work around incorrect noise and power values
1579 returned by some broken drivers.
1581 2008-06-03, Version 4.4.1
1582 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1583 to kyrone for reporting this.
1584 * collectd: Fixed min/max output in notifications generated by
1585 threshold checking.
1586 * collectd-nagios: Fix the protocol used to communicate with the
1587 daemon.
1588 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1589 initialization has errors. An issue with Perl 5.10 has been fixed.
1590 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1591 René Rebe and Siegmund Gorr for reporting this.
1593 2008-05-06, Version 4.4.0
1594 * collectd: Internal code cleanups.
1595 * collectd: Added support for a `Flush' command in the unixsock and
1596 exec plugins. This command can be used to force a plugin (or all) to
1597 flush its values to disk.
1598 * collectd: Thresholds can now be configured to apply to one data
1599 source only, making it possible to configure different thresholds
1600 for each data source.
1601 * apache, nginx plugins: Added the possibility to disable host and/or
1602 peer verification.
1603 * ascent plugin: The new ascent plugin reads and parses the statistics
1604 page of an Ascent server.
1605 * cpu plugin: Support for the statgrab library has been added.
1606 * disk plugin: The possibility to ignore certain disks or collect only
1607 specific disks has been added.
1608 * disk plugin: Support for the statgrab library has been added.
1609 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1610 sensor values via IPMI, the intelligent platform management
1611 interface.
1612 * iptables plugin: The iptc library that is used by the iptables
1613 plugin has been added to the distribution, because it is not
1614 provided by all distributions and removed from at least one.
1615 * powerdns plugin: The new powerdns plugin reads statistics from an
1616 authoritative or a recursing PowerDNS name server.
1617 * rrdtool plugin: The size of the files generated with the default
1618 configuration has been decreased.
1619 * tail plugin: The new tail plugin can be used to gather statistics by
1620 continuously reading from log files.
1621 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1622 TeamSpeak2 server and collects statistics about the number of users
1623 and number of channels.
1624 * users plugin: Support for the statgrab library has been added.
1625 * vmem plugin: The new vmem plugin collects very detailed statistics
1626 about the virtual memory subsystem of Linux.
1628 2008-08-30, Version 4.3.4
1629 * Build system: Improved detection of and linking with the statgrab
1630 library.
1631 * collectd: Portability fixes, especially to determine endianess more
1632 reliable.
1633 * Various plugins: Fix format strings.
1634 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1635 again has been applied.
1636 * memcached plugin: Fix a too short timeout and a related file
1637 descriptor leak.
1638 * memory plugin: A typo in the libstatgrab code has been fixed.
1639 * network plugin: A fix in the initialization function solves problems
1640 under Solaris.
1641 * nginx plugin: A thread-unsafe function has been replaced.
1642 * vserver plugin: A thread-unsafe function has been replaced.

1644 added.
1646 2008-04-22, Version 4.3.3
1647 * build system: Improved detection of several libraries, especially if
1648 they are in non-standard paths.
1649 * build system: Portability fixes: Automatically define "_REENTRANT"
1650 if the libc expects it.
1651 * collectd: Error and warning messages have been improved.
1652 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1653 using them.
1654 * apache plugin: Allocate new memory when reading a webpage instead of
1655 using a buffer of static size.
1656 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1657 the program.
1658 * hddtemp plugin: Error and warning messages have been improved.
1659 * sensors plugin: Fix sensor collection for some chip types.
1661 2008-03-29, Version 4.3.2
1662 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1663 `Persist' threshold options.
1664 * collectd: Fix handling of missing values in the global value cache.
1665 * collectd: Improved error messages when parsing the configuration.
1666 * sensors plugin: Fix temperature collection with libsensors4.
1667 * unixsock plugin: Fix mixed input and output operation on streams.
1668 * wireless plugin: Fix reading noise value.
1670 2008-03-05, Version 4.3.1
1671 * exec plugin: Set supplementary group IDs.
1672 * network plugin:
1673 + Use `memcpy' when constructing/parsing a package to avoid
1674 alignment problems on weird architectures, such as Sparc.
1675 + Translate doubles to/from the x86 byte representation to ensure
1676 cross-platform compatibility.
1677 * ping plugin: Correct the handling of the `TTL' setting.
1678 * swap plugin: Reapply a patch for Solaris.
1679 * tcpconns plugin: Portability improvements.
1681 2008-02-18, Version 4.3.0
1682 * collectd: Notifications have been added to the daemon. Notifications
1683 are status messages that may be associated with a data instance.
1684 * collectd: Threshold checking has been added to the daemon. This
1685 means that you can configure threshold values for each data
1686 instance. If this threshold is exceeded a notification will be
1687 created.
1688 * collectd: The new `FQDNLookup' option tells the daemon to use the
1689 full qualified domain name as the hostname, not just the host part
1690 es returned by `gethostname(2)'.
1691 * collectd: Support for more than one `TypesDB' file has been added.
1692 This is useful when one such file is included in a package but one
1693 wants to add custom type definitions.
1694 * collectd: The `Include' config option has been expanded to handle
1695 entire directories and shell wildcards.
1696 * collectdmon: The new `collectdmon' binary detects when collectd
1697 terminates and automatically restarts it again.
1698 * csv plugin: The CSV plugin is now able to store counter values as a
1699 rate, using the `StoreRates' configuration option.
1700 * exec plugin: Handling of notifications has been added and the
1701 ability to pass arguments to the executed programs has been added.
1702 * hddtemp plugin: The new `TranslateDevicename' option lets you
1703 disable the translation from device names to major-minor-numbers.
1704 * logfile plugin: Handling of notifications has been added.
1705 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1706 domain name lookups in this plugin.
1707 * perl plugin: Many internal changes added support for handling multiple
1708 threads making the plugin reasonably usable inside collectd. The API has
1709 been extended to support notifications and export global variables to
1710 Perl plugins; callbacks now have to be identified by name rather than a
1711 pointer to a subroutine. The plugin is no longer experimental.
1712 * uuid plugin: The new UUID plugin sets the hostname to an unique
1713 identifier for this host. This is meant for setups where each client
1714 may migrate to another physical host, possibly going through one or
1715 more name changes in the process. Thanks to Richard Jones from
1716 Red Hat's Emerging Technology group for this plugin.
1717 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1718 CPU, disk and network statistics about guest systems on the same
1719 physical server. Thanks to Richard Jones from Red Hat's Emerging
1720 Technology group for this plugin.
1722 2008-04-22, Version 4.2.7
1723 * build system: Improved detection of several libraries, especially if
1724 they are in non-standard paths.
1725 * build system: Portability fixes: Automatically define "_REENTRANT"
1726 if the libc expects it.
1727 * collectd: Error and warning messages have been improved.
1728 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1729 using them.
1730 * apache plugin: Allocate new memory when reading a webpage instead of
1731 using a buffer of static size.
1732 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1733 the program.
1734 * hddtemp plugin: Error and warning messages have been improved.
1735 * sensors plugin: Fix sensor collection for some chip types.
1737 2008-03-29, Version 4.2.6
1738 * collectd: Improved error messages when parsing the configuration.
1739 * sensors plugin: Fix temperature collection with libsensors4.
1740 * unixsock plugin: Fix mixed input and output operation on streams.
1741 * wireless plugin: Fix reading noise value.
1743 2008-03-04, Version 4.2.5
1744 * apache plugin: Improved initialization and error messages.
1745 * exec plugin: Set supplementary group IDs.
1746 * network plugin:
1747 + Create separate threads for reading from the socket and parsing
1748 and dispatching incoming packets. Versions prior to this may have
1749 problems in high-load situations, where the socket receive buffers
1750 overflows, resulting in gaps in the data.
1751 + Use `memcpy' when constructing/parsing a package to avoid
1752 alignment problems on weird architectures, such as Sparc.
1753 + Translate doubles to/from the x86 byte representation to ensure
1754 cross-platform compatibility.
1755 * ping plugin: Correct the handling of the `TTL' setting.
1756 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1757 * swap plugin: Reapply a patch for Solaris.
1758 * tcpconns plugin: Portability improvements.
1760 2008-01-21, Version 4.2.4
1761 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1762 the permission on the socket as documented in the manpage. Thanks to
1763 Evgeny Chukreev for fixing this issue.
1764 * collectd: The documentation has been improved.
1766 2007-12-28, Version 4.2.3
1767 * sensors plugin: Updated the plugin to build and work with version 3
1768 of the libsensors library.
1770 2007-12-15, Version 4.2.2
1771 * nginx plugin: Incorrect comparison of strings lead to a segfault
1772 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1773 this.
1774 * logfile plugin: The config option `Timestamp' was handled
1775 incorrectly and basically always active. Thanks to Luke Heberling
1776 for fixing this.
1778 2007-11-08, Version 4.2.1
1779 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1780 enabled on the host.
1781 * snmp plugin: Fix a memory leak.
1783 2007-10-27, Version 4.2.0
1784 * collectd: The new config option `Include' lets you include other
1785 configfiles and thus split up your config into smaller parts. This
1786 may be especially interesting for the snmp plugin to keep the data
1787 definitions separate from the host definitions.
1788 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1789 (number of connections, octets and packets for each service and
1790 destination). Thanks to Sebastian Harl for this plugin.
1791 * memcached plugin: The new `memcached' plugin connects to a memcached
1792 daemon process and collects statistics of this distributed caching
1793 system. Thanks to Antony Dovgal for contributing this plugin.
1794 * nginx plugin: The new `nginx' plugin reads the status page of an
1795 nginx daemon and saves the handled connections and requests.
1796 * perl plugin: Many changes, including the added `EnableDebugger'
1797 config option which lets you debug your Perl plugins more easily.
1798 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1799 be more thread-safe otherwise by locking calls to the library.
1800 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1801 correct the values returned by SNMP-agents. If a <data> block is
1802 defined as `table' the instance is now optional. The sequence number
1803 is used as the type-instance in this case. The new `InstancePrefix'
1804 option allows to add arbitrary prefixes to the type-instance.
1805 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1806 certain TCP connections and what state they're in. This can be used
1807 to see how many connections your FTP server has to handle or how
1808 many outgoing connections your mailserver has open.
1810 2008-01-11, Version 4.1.6
1811 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1812 the permission on the socket as documented in the manpage. Thanks to
1813 Evgeny Chukreev for fixing this issue.

1820 of the libsensors library.
1822 2007-11-08, Version 4.1.4
1823 * Build system: Improve detection of the rrd library, especially if
1824 it's in a non-standard location.
1825 * Build system: A bug when parsing the argument for
1826 `--with-libnetsnmp' has been fixed.
1827 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1828 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1829 a deadlock or delay when shutting down the daemon.
1830 * snmp plugin: Fix a memory leak.
1832 2007-10-24, Version 4.1.3
1833 * collectd: A build issue under Solaris has been resolved by renaming
1834 data types.
1835 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1836 be more thread-safe otherwise by locking calls to the library.
1838 2007-09-28, Version 4.1.2
1839 * apcups plugin: Fix reporting of the `load percent' data.
1840 * wireless plugin: Correct the handling of cards returning signal and
1841 noise quality as percentage.
1842 * perl plugin: Fix a possible buffer overflow in get_module_name().
1843 * build system: Further improve the detection of libraries.
1844 * netlink plugin: Build issues under some older versions of the Linux
1845 includes (i. e. Debian Sarge) have been fixed.
1846 * snmp plugin: Fix a potential segfault when a host times out. Add
1847 support for the `timeticks' type.
1849 2007-09-12, Version 4.1.1

1853 fixed.
1854 * collectd: The `sstrerror' function was improved to work correctly
1855 with the broken GNU version of `strerror_r'.
1856 * collectd: Write an error message to STDERR when loading of a plugin
1857 fails.
1858 * apcups plugin: Fix the `types' used to submit the values: They still
1859 has an `apcups_' prefix which doesn't work anymore.
1860 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1861 whatever the client thinks is `now'..
1863 2007-09-01, Version 4.1.0
1864 * Build system: The build system has been changed to automatically
1865 disable all plugins, which are missing dependencies. The dependency
1866 checking has been removed from the plugins themselves to remove
1867 redundancy.
1868 * Flexible interval: The interval of collected data is now sent along
1869 with the data itself over the network, so that the interval-settings
1870 of server and clients no longer needs to match.
1871 * netlink plugin: The new `netlink' plugin connects to the Linux
1872 kernel using a netlink socket and uses it to query information about
1873 interfaces, qdiscs and classes.
1874 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1875 to not block data collection.
1876 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1877 network devices, such as switches, routers, thermometers, rack

1879 plugin.
1880 * unixsock plugin: Added the `LISTVAL' command.
1881 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1882 of music played with xmms.

1885 * apcups plugin: Fix reporting of the `load percent' data.
1886 * wireless plugin: Correct the handling of cards returning signal and
1887 noise quality as percentage.
1888 * perl plugin: Fix a possible buffer overflow in get_module_name().
1890 2007-09-12, Version 4.0.8
1891 * collectd: The `sstrerror' function was improved to work correctly
1892 with the broken GNU version of `strerror_r'.
1893 * collectd: Write an error message to STDERR when loading of a plugin
1894 fails.
1895 * apcups plugin: Fix the `types' used to submit the values: They still
1896 has an `apcups_' prefix which doesn't work anymore.
1897 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1898 whatever the client thinks is `now'..
1900 2007-08-26, Version 4.0.7
1901 * documentation: Some typos have been fixed and some information has
1902 been improved.
1903 * build system: Many fixes for detecting libraries in unusual places,
1904 such as on RedHat systems. The affected libraries are `libcurl',
1905 `libmysql', and `libupsclient'.
1906 * network plugin: Allow the `Port' option to be specified as a number
1907 (i. e. without quotes).
1908 * nut plugin: A fix allows linking the nut plugin against
1909 libupsclient, version >= 2.2.0.
1910 * processes plugin: Fix a potential segmentation fault.
1912 2007-07-30, Version 4.0.6
1913 * sensors plugin: Fix the ignorelist functionality: Only the `type
1914 instance' was used to match against the list, but the documentation
1915 told otherwise. This release fixes the code, so it complies with the
1916 documentation.
1917 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1918 configuration messages will end up in the logging facility.
1919 * conrtib/fedora: The contributed specfile for Fedora has been
1920 updated.
1922 2007-07-05, Version 4.0.5
1923 * Portability: More fixes for OpenBSD have been included.
1925 2007-06-24, Version 4.0.4
1926 * cpu plugin: Fixed the Solaris code.
1927 * dns plugin: Fixed a build issue for OpenBSD.
1928 * interface plugin: Fixed the Solaris code.
1929 * load plugin: Fixed the alternative `/proc' Linux code.
1930 * memory plugin: Fixed the Solaris code.
1931 * oconfig: Don't require `-lfl' anymore.
1933 2007-06-19, Version 4.0.3
1934 * cpu plugin: Fix the Darwin / Mac OS X code.
1935 * ping plugin: Use the return value of `getpid', not its address.
1936 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1937 initialized correctly.
1938 * configure: Added `--with-nan-emulation' to aid cross compilation.
1940 2007-06-12, Version 4.0.2
1941 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1942 they're given in numerically form.
1944 2007-06-07, Version 4.0.1
1945 * iptables plugin: A bug in the configuration routine has been fixed.
1946 Setting a comment in the configfile will no longer cause a
1947 segmentation fault.
1949 2007-06-03, Version 4.0.0
1950 * collectd: The plugin-infrastructure has been changed to allow for
1951 more types of plugins, namely `write' and `log' plugins.
1952 * collectd: The read-function has been changed to read many plugins in
1953 parallel, using threads. Thus, plugins generally need to use
1954 thread-safe functions from now on.
1955 * collectd: The '-t' command line options allows to perform syntax tests
1956 of the configuration file and exit immediately.
1957 * csv plugin: The new `csv' plugin handles output to `comma separated
1958 values'-files.
1959 * rrdtool plugin: The new `rrdtool' plugin handles output to
1960 RRD-files. Data can be cached to combine multiple updates into one
1961 write to increase IO-performance.
1962 * network plugin: The new `network' plugin handles IO via the network.
1963 It implements a different, much more extensible protocol which can
1964 combine many values in one packet, decreasing the number of UDP-
1965 packets being sent. It can read from and send to the network and
1966 with the appropriate configuration even forward packets to other
1967 networks.
1968 * unixsock plugin: The new `unixsock' plugin provides an interface to
1969 communicate with the daemon while it is running. Right now the
1970 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1971 come.
1972 * perl plugin: The new `perl' plugin allows you to write extensions
1973 for collectd in the scripting-language Perl.
1974 * logfile plugin: The new `logfile' plugin writes logmessages to files
1975 or STDOUT or STDERR.
1976 * syslog plugin: The new `syslog' plugin sends logmessages to the
1977 system's syslog daemon.
1978 * entropy plugin: The new `entropy' plugin collects the amount of
1979 entropy currently being available to the system.
1980 * exec plugin: The new `exec' plugin forks child processes and reads
1981 back values provided by the forked processes.
1982 * iptables plugin: The new `iptables' plugin reads counters from
1983 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1984 plugin.
1985 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1986 to Peter Holik for contributing this plugin.
1987 * nut plugin: The new `nut' plugin connects the upsd of the `network
1988 ups tools' and reads information about the connected UPS.
1989 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1990 connections) field was added by Florent Monbillard.
1991 * collectd-nagios: The new `collectd-nagios' binary queries values
1992 from collectd, parses them and exits according to Nagios-standards.
1993 * manpages: The manpages have been improved a lot.
1995 2007-09-28, Version 3.11.7
1996 * wireless plugin: Correct the handling of cards returning signal and
1997 noise quality as percentage.
1999 2007-08-31, Version 3.11.6
2000 * processes plugin: Fix a potential segmentation fault.
2002 2007-05-29, Version 3.11.5
2003 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2004 * ntpd plugin: Fix a potential buffer overflow.
2005 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2006 were accounted as `zombies'.
2008 2007-04-10, Version 3.11.4
2009 * dns plugin: Change the order of includes to make the plugin compile
2010 under FreeBSD.
2012 2007-03-30, Version 3.11.3
2013 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2014 of the unused `COLLECT_KSTAT'.
2016 2007-02-11, Version 3.11.2
2017 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2018 NULL-pointer may have been passed to `printf' which causes a
2019 segfault with some libcs.
2021 2007-02-10, Version 3.11.1
2022 * df plugin: Some wrong defines have been fixed so the plugin works
2023 under Solaris again.
2024 * dns plugin: The usage of a struct has been fixed to work with
2025 non-GNU libcs.
2026 * processes plugin: Some missing defines have been added so the plugin
2027 compiles cleanly under FreeBSD and presumably other UNIXes.
2029 2006-12-22, Version 3.11.0
2030 * collectd: The new command line option `-P' makes it easier for
2031 distributors to change the location of PID-files.
2032 * collectd: The daemon shuts down faster now which makes it easier to
2033 write init.d-scripts for it.
2034 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2035 caused problems every now and then.
2036 * df plugin: New config options allow to ignore certain mountpoints,
2037 filesystem types or devices.
2038 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2039 and interprets it. It collects traffic as well as qtype, opcode and
2040 rcode counts.
2041 * email plugin: Sebastian Harl has contributed this plugin which
2042 counts received mails in categories (e. g. ham, spam, virus), spam
2043 score (as given by SpamAssassin) and check types.
2044 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2045 uses `mbmon' to gather information from sensors on the motherboard.
2046 * processes plugin: Collect detailed statistics for configured
2047 processes, that's process and thread count, CPU usage, resident
2048 segment size and pagefaults.
2049 * multimeter plugin: Peter Holik contributed a new plugin which
2050 queries multimeters.
2051 * sensors plugin: Lubos Stanek has put much effort into improving this
2052 plugin, including `extended naming', collection of voltage values
2053 and the possibility to ignore certain values.
2055 2006-12-21, Version 3.10.4
2056 * Max Kellermann has identified a bug in the server routine: When
2057 opening a socket fails the daemon will (re)try opening the socket in
2058 an endless loop, ultimately leading to a `EMFILE' error.
2060 2006-11-04, Version 3.10.3
2061 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2062 ntpd's reply was sent in more than one packet, the buffer size was
2063 calculated incorrectly, resulting in the reading of uninitialized or
2064 freed memory.
2066 2006-11-01, Version 3.10.2
2067 * The sample config file has been improved.
2068 * Errors in the manpages have been corrected.
2069 * The ping-plugin now adds hosts during initialization, not during
2070 startup. This speeds up startup when no network connectivity is
2071 available. Also, the hosts are being added later when the network is
2072 available.
2073 * Improved BSD-support for the df-plugin.
2074 * Fixed syntax errors in the swap-plugin for Mac OS X.
2075 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2076 plugin.
2077 * Don't disable the mysql-plugin if connecting to the database fails
2078 during initialization. Instead, try again in increasing intervals.
2080 2006-07-19, Version 3.10.1
2081 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2082 the apcups cannot be reached, unconnected sockets will pile up and
2083 eventually lead to `Too many open files' errors.
2085 2006-07-09, Version 3.10.0
2086 * The `disk' plugin has been ported to Darwin.
2087 * The `battery' plugin should work on many Apple computers now.
2088 * The `traffic' plugin can now ignore certain interfaces. Also,
2089 statistics for sent/received packets and errors have been added.
2090 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2091 to Anthony Gialluca for contributing this plugin and providing me
2092 with a test environment :)
2093 * A plugin for monitoring an NTP instance and the local clock drift
2094 has been added.
2096 2006-06-25, Version 3.9.4
2097 * The Solaris code in the `swap' plugin has been changed to reflect
2098 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2099 working this out.
2100 * The debugging system has been fixed to work with the Sun libc.
2101 * When built without librrd the variable `operating_mode' could be
2102 uninitialized. Thanks to David Elliot for reporting the bug.
2104 2006-06-01, Version 3.9.3
2105 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2106 operating systems also profit from the changes, but I wasn't able to
2107 check that.
2108 * Changed the build system to find the netinet-includes under FreeBSD
2109 and therefore successfully build the `liboping' library there.
2111 2006-05-09, Version 3.9.2
2112 * Applied a patch to the `liboping' library. Due to a bug in the
2113 sequence checking the `ping' plugin stopped working after
2114 approximately 7.6 days.
2116 2006-05-09, Version 3.8.5
2117 * Applied a patch to the `liboping' library. Due to a bug in the
2118 sequence checking the `ping' plugin stopped working after
2119 approximately 7.6 days.
2121 2006-04-21, Version 3.9.1
2122 * Build issues with Solaris and possible other architectures have been
2123 resolved.
2124 * Problems when building the `apache'-plugin without `libcurl' have
2125 been resolved.
2126 * A bug in the `ping' plugin has been fixed. Sorry folks.
2128 2006-04-02, Version 3.9.0
2129 * A plugin to monitor the Apache webserver has been added.
2130 <http://httpd.apache.org/>
2131 * A plugin to collect statistics about virtual servers using VServer.
2132 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2133 this plugin :)
2134 * A plugin for wireless LAN cards has been added. It monitors signal
2135 strength, link quality and noise ratio..
2136 * A plugin for Apple hardware sensors has been added.
2137 * An option to compile collectd with different `step' and `heartbeat'
2138 settings has been added. The size of RRAs is no longer static but
2139 calculated based on the settings for `step' and `width'.
2140 * The `ping' plugin can now be configured to use a certain TTL.
2141 * A plugin to monitor the hardware sensors of Apple computers has been
2142 added.
2143 * The plugins `cpu', `memory', `processes' and `traffic' have been
2144 ported to Mach/Darwin (Mac OS X).
2145 * The `log mode' has been contributed by Christophe Kalt. It writes
2146 the data into text files rather than RRD files.
2148 2006-04-09, Version 3.8.4
2149 * Applied patch by Vincent Stehlé which improves the disk-name
2150 resolution in the `hddtemp' plugin for Linux systems.
2152 2006-04-02, Version 3.8.3
2153 * Applied a patch by James Byers: The MySQL plugin was not working
2154 with MySQL 5.0.2 or later.
2156 2006-03-14, Version 3.8.2
2157 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2158 the GNU libc, because it points to `/etc/fstab' rather than
2159 `/etc/mtab'.
2161 2006-03-13, Version 3.8.1
2162 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2163 * Fixes in the debian `postinst' and `init.d' scripts.
2165 2006-03-09, Version 3.8.0
2166 * The `ping' plugin no longer uses `libping' but a self written
2167 library named `liboping'. With this library it's possible to ping
2168 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2170 2006-02-18, Version 3.7.2
2171 * A simple bug in the `battery' plugin has been fixed. It should now
2172 work with ACPI based batteries as well. Thanks to Sebastian for
2173 fixing this.
2174 * Fixing a bug that prevented collectd to be built without librrd.
2175 Thanks to Werner Heuser for reporting it.
2177 2006-02-04, Version 3.7.1
2178 * The new network code has been improved to build with older versions
2179 of glibc.
2180 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2181 to Tommie Gannert for this patch.
2183 2006-01-30, Version 3.7.0
2184 * The `battery' plugin has been added. It collects information about
2185 laptop batteries..
2186 * The MySQL plugin has been improved: It now writes two more RRD
2187 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2188 * The `cpufreq' plugin now reads another file since the file it did
2189 read so far causes much overhead in the kernel. Also, you need root
2190 to read the old file, but not to read the new one.
2191 * The `hddtemp' plugin can now be configured to connect to another
2192 address and/or port than localhost.
2193 * The `df' plugin now prefers `statvfs' over `statfs'.
2194 * The network code has been rewritten. collectd now supports unicast
2195 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2196 be set in the configfile.
2198 2006-01-24, Version 3.6.2
2199 * Due to a bug in the configfile handling collectd wouldn't start in
2200 client mode. This released fixes this.
2202 2006-01-20, Version 3.6.1
2203 * Due to a bug in `configure.in' all modules and the binary were
2204 linked against `libmysqlclient'. This issue is solved by this
2205 release.
2207 2006-01-17, Version 3.6.0
2208 * A config file has been added. This allows for loading only specific
2209 plugins.
2210 * A `df' plugin has been added.
2211 * A `mysql' plugin has been added.
2212 * The `ping' plugin doesn't entirely give up hope when a socket error
2213 occurred, but will back of and increase the intervals between tries.
2215 2006-01-21, Version 3.5.2
2216 * Fixed yet another bug in the signal handling.. Stupid typo..
2217 * Improved the ping plugin to not give up on socket errors (backport
2218 from 3.6.0).
2220 2005-12-18, Version 3.5.1
2221 * The PID-file is now deleted correctly when shutting down the daemon.
2222 * SIGINT and SIGTERM are now handled correctly.
2224 2005-12-16, Version 3.5.0 (Revision 326)
2225 * A bug in the `load' module under Solaris has been fixed.
2226 * The `users' module has been contributed by Sebastian Harl. It counts
2227 currently logged in users.
2228 * The CPU module now works under FreeBSD without the use of
2229 `libstatgrab', however SMP support is missing.
2230 * The default directories for the RRD files and the PID file now
2231 depend on the compile time setting of `localstatedir'.
2233 2005-11-15, Version 3.4.0 (Revision 236)
2234 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2235 from gentoo's bugzilla for writing the patch.
2236 * The build dependency for librrd has been removed. Binaries built
2237 without librrd are client-only and will multicast their value as
2238 with the `-c' argument.
2239 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2240 * The newly introduced `-f' switch prevents daemon initialization
2241 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2242 Barcellos for this patch.
2244 2005-11-04, Version 3.3.0 (Revision 216)
2245 * New modules have been added:
2246 - `serial', for monitoring traffic on the serial interfaces
2247 - `nfs', for graphing NFS procedure calls
2248 - `tape', traffic from/to tape devices
2249 * The memory.rrd now accepts more than 4Gig of memory.
2251 2005-10-26, Version 3.2.0 (Revision 200)
2252 * Support for graphing the processes has been added (thanks to Lyonel
2253 Vincent)
2254 * If reading from hddtemp fails collectd will increase the time
2255 between polls up to one day.
2256 * The init.d files have been improved.
2257 * Problems with the spec file have been fixed.
2259 2005-10-16, Version 3.1.0 (Revision 194)
2260 * Added the `setsid' syscall to the startup code.
2261 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2263 2005-09-30, Version 3.0.0 (Revision 184)
2264 * The ability to send/receive data to/from the network (think
2265 multicast) has been added.
2266 * Modules have been split up into shared libraries can be loaded at
2267 runtime. The biggest advantage is that the core program doesn't need
2268 to be linked against an external library.
2269 * A patch by George Kargiotakis has been applied: It fixes the sensors
2270 behaviour then more than one sensor is being queried.
2272 2005-09-16, Version 2.1.0 (Revision 172)
2273 * A module for swap statistics has been added.
2275 2005-09-09, Version 2.0.0 (Revision 135)
2276 * Filenames can no longer be configured at program startup. The only
2277 options as of this version are the directory and ping hosts.
2278 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2279 Soft-IRQ statistics are added to `System'.
2280 * Diskstats now collect read and write bytes, not sectors.
2281 * Ping statistics can now be collected for more than one host. There
2282 is no default any more: If no host is given no host will be pinged.
2283 * A self-written patch for libping has been applied so it builds
2284 cleanly.
2286 2005-09-01, Version 1.8.1 (Revision 123)
2287 * Much improved configure-script: libraries and features may now be
2288 disabled.
2289 * More detailed warnings/error messages when RRD update fails.
2291 2005-08-29, Version 1.8.0:
2292 * Support for collecting disk statistics under Solaris.
2294 2005-08-25, Version 1.7.0:
2295 * Support for libstatgrab[1] for load, memory usage and network
2296 traffic. CPU- and disk-usage are not (yet) supported, since
2297 libstatgrab returns insufficient information. I will contact the
2298 authors.
2299 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2300 aren't necessarily counted linear which is now handled correctly.

2303 2005-08-21, Version 1.6.0:
2304 * Basic support for Solaris: System load and cpu-usage can be
2305 collected under Solaris, too. Other stats will follow later.
2306 * Many fixes in the autoconf-script
2307 * Collection/Museum scripts have been added under contrib/museum
2308 * collectd may now be started in unprivileged mode, though ping
2309 statistics will not work.
2311 2005-07-17, Version 1.5.1:
2312 * Diskstats-RRDs now use major/minor for naming. Some systems have
2313 weird strings as disk-names..
2315 2005-07-17, Version 1.5:
2316 * A new module, diskstats, has been added. It collects information
2317 about the disks and partitions.
2319 2005-07-11, Version 1.4.2:
2320 * The meminfo module has been changed to work with more platforms
2321 and/or kernel versions.
2323 2005-07-10, Version 1.4.1: Correct traffic stats
2324 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2325 forgot to correct when I changed that module.
2327 2005-07-09, Version 1.4: More traffic stats
2328 * Traffic is now collected for all interfaces that can be found
2329 * Temperature-statistics are read from lm-sensors if available
2331 2005-07-08, Version 1.3: CPU stats
2332 * Collecting CPU statistics now
2334 2005-07-12, Version 1.2: Using syslog
2335 * collectd is now using the syslog facility to report errors, warnings
2336 and the like..
2337 * The default directory is now /var/db/collectd
2339 2005-07-10, Version 1.1: Minor changes
2340 * Nothing really useful to say ;)
2342 2005-07-09, Version 1.0: Initial Version
2343 * The following modules are provided:
2344 * Load average
2345 * Ping time
2346 * Traffic
2347 * Memory info
