1057 This way the “GETVAL” command of the UnixSock plugin doesn't return
1058 old, no longer valid values when this happens. Thanks to Andrés J.
1060 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1061 to follow redirects. Thanks to Joey Hess for reporting this bug.

1111 * liboping: A patch to comply with strict aliasing rules has been
1113 * timediff match: Fix a typo: The match was registered with a wrong
1114 name which prevented this match to be used as documented. Thanks to
1115 Bruno Prémont for finding this problem.
1116 * bind plugin: Fix collection of the cached RR sets. The number of RR
1117 sets currently in the cache was collected as a counter value, which
1118 is nonsense. Thanks to Bruno Prémont for implementing this.
1119 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1120 primarily BSDs, don't take it well and crash.
1121 * oracle plugin: Portability to 64 bit systems has been improved.
1122 * postgresql plugin: The default configuration has been improved.
1123 * rrdtool plugin: Fix a possible race condition: If the network plugin

1134 faults. Thanks to Peter Holik for his patch.
1136 2009-02-16, Version 4.6.0
1137 * collectd: Added the `filter chain' infrastructure, which allows the
1138 user to use `matches' and `targets' to control value processing.
1139 * collectd: The new `-T' command line argument allows more in-depth
1140 testing of a configuration. Thanks to Doug MacEachern for the patch.

1159 example for native OpenBSD support, has been added. Thanks to Simon
1160 Kuhnle for the patch.
1161 * csv plugin: Make it possible to write values to STDOUT instead of
1162 files. This is meant for testing purposes mostly. The output written
1163 to STDOUT is compatible with the exec plugin. Thanks to Doug
1164 MacEachern for the patch.
1165 * curl plugin: This new plugin can be used to read web pages and parse
1166 them using the same mechanism that's used in the tail plugin.
1167 * dbi plugin: This new plugin allows you to connect to a variety of
1168 relational databases and use SQL to gather custom statistics from
1169 it. It is similar to the already existing PostgreSQL plugin but uses
1170 libdbi to communicate with the database(s).
1171 * interface plugin: Use the ignorelist framework when selecting /
1172 ignoring interfaces. This allows one to use regular expressions to
1173 select interfaces, too.
1174 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1175 Thanks to Bruno Prémont for this patch.
1176 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

1192 allowing plugins to register `matches' and `targets'.
1193 * postgresql plugin: The preferred configuration syntax has been
1194 updated to be in line with the syntax used by the new dbi and oracle
1195 plugins. The compatibility code for the old syntax is present.
1196 Support for the new `Result' blocks and the interval parameter has
1198 * processes plugin: Stacksize and virtual memory usage statistics have
1199 been added. Portability fixes.
1200 * rrdcached plugin: This new plugin uses the (still in development)
1201 RRD accelerator daemon, rrdcached. This daemon works very similar to
1202 the original rrdtool plugin of collectd, but adds some more nice
1204 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1207 2009-05-09, Version 4.5.4
1208 * Build system, various plugins: Many build fixes for FreeBSD,

1221 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1223 * rrdtool plugin: Fix a possible race condition: If the network plugin
1224 is initialized and dispatches a value before the rrdtool plugin is
1225 initialized, the daemon may crash.
1226 * memory plugin: Fix a potential problem under Solaris.
1228 2009-02-22, Version 4.5.3

1238 code. Thanks to "thated" for reporting this.
1240 2009-01-02, Version 4.5.2
1241 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1242 file may be in both locations, especially when the database was
1243 installed in a non-standard path. Thanks to Dusty Doris for
1245 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1246 Solaris, in the configure script automatically.
1247 * build system, tcpconns plugin: Check for `kvm_nlist' and
1248 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1249 library with similar functions to the BSD variant, but doesn't
1250 provide these necessary functions.
1251 * collectd.conf(5): Various fixes and clarifications.
1252 * collectd: Remove a GNUism (unnamed unions), thus improving

1257 * filecount plugin: Fix an off-by-one error. This error may cause a
1259 * network plugin: Fix the handling of `type' in the network protocol.
1260 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1261 much larger buffer. This caused the `type' to be transferred much
1262 more often than necessary. In some cases, e. g. the `cpu' and
1263 `cpufreq' plugins being used at the same time, data may be corrupted
1264 in those files. Thanks to Bruno Prémont for debugging and reporting
1266 * processes plugin: Fix a possible segmentation fault when specifying
1267 invalid configuration options.
1268 * unixsock plugin: Make sure the initialization function is run only
1269 once. This resolves a file descriptor leak under systems which run
1270 the initialization more than once, such as Solaris.
1272 2008-10-16, Version 4.5.1
1273 * build system: Change `--enable-<plugin>' to abort with an error if
1274 dependencies are not met. Thanks to Bruno Prémont for the patch.
1275 Also, the poisoning of various string functions has been restricted
1277 * collectd: Fix a memory leak in the global value cache. With every
1278 *missing* value a couple of bytes would be leaked. Another memory
1279 leak in the configuration handling code has been fixed. Thanks to
1280 Niraj Tolia for reporting these issues.
1281 * collectd: Fix an off-by-one error in the ignorelist functionality.
1282 When using regular expressions, the last character would be missing,
1283 possibly matching differently from what one would expect.
1284 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1286 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1287 Linzberger for reporting the bug.
1288 * iptables plugin: Fix an off-by-one error. If a string was just one
1289 character too long, it was truncated instead of reporting an error.
1290 * network plugin: Fix a memory leak in the configuration handling
1291 code. Thanks to Niraj Tolia for reporting this issue.
1292 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1293 * postgresql plugin: Don't reopen connection during reinitialization.
1294 This fixes a bug under Solaris and potentially other platforms.

1296 leaks. Thanks to ``Admin'' for reporting these bugs.
1297 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1299 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1300 problems with some `libc's. Thanks to Matthias Lay for reporting the
1303 2008-09-04, Version 4.5.0
1304 * collectd: Added the ability to flush certain identifiers.

1312 X desktop using the structure defined in the `Desktop Notification
1314 * notify_email plugin: This new plugin sends out notifications via
1315 email, using the `esmtp' library.
1316 * onewire plugin: The new experimental(!) onewire plugin reads values,
1317 such as temperatures, from sensors connected to the computer via the
1319 * perl plugin: Improved synchronized access to internal data structures
1320 and fixed a possible dead-lock.
1321 * perl plugin: Added the ability to flush certain identifiers and marked
1322 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1324 * perl plugin: Added the ability to configure Perl plugins.

1345 * network plugin: Fix the handling of `type' in the network protocol.
1346 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1347 much larger buffer. This caused the `type' to be transferred much
1348 more often than necessary. In some cases, e. g. the `cpu' and

1418 exec plugins. This command can be used to force a plugin (or all) to
1419 flush its values to disk.
1420 * collectd: Thresholds can now be configured to apply to one data
1421 source only, making it possible to configure different thresholds
1422 for each data source.
1423 * apache, nginx plugins: Added the possibility to disable host and/or
1425 * ascent plugin: The new ascent plugin reads and parses the statistics
1426 page of an Ascent server.

1464 * vserver plugin: A thread-unsafe function has been replaced.
1465 * wireless plugin: A work-around for broken wireless drivers has been
1468 2008-04-22, Version 4.3.3
1469 * build system: Improved detection of several libraries, especially if
1470 they are in non-standard paths.
1471 * build system: Portability fixes: Automatically define "_REENTRANT"
1472 if the libc expects it.
1473 * collectd: Error and warning messages have been improved.
1474 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1476 * apache plugin: Allocate new memory when reading a webpage instead of
1477 using a buffer of static size.
1478 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1480 * hddtemp plugin: Error and warning messages have been improved.
1481 * sensors plugin: Fix sensor collection for some chip types.
1483 2008-03-29, Version 4.3.2
1484 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1485 `Persist' threshold options.
1486 * collectd: Fix handling of missing values in the global value cache.
1487 * collectd: Improved error messages when parsing the configuration.
1488 * sensors plugin: Fix temperature collection with libsensors4.
1489 * unixsock plugin: Fix mixed input and output operation on streams.
1490 * wireless plugin: Fix reading noise value.
1492 2008-03-05, Version 4.3.1
1493 * exec plugin: Set supplementary group IDs.
1495 + Use `memcpy' when constructing/parsing a package to avoid
1496 alignment problems on weird architectures, such as Sparc.
1497 + Translate doubles to/from the x86 byte representation to ensure
1498 cross-platform compatibility.
1499 * ping plugin: Correct the handling of the `TTL' setting.
1500 * swap plugin: Reapply a patch for Solaris.
1501 * tcpconns plugin: Portability improvements.
1503 2008-02-18, Version 4.3.0
1504 * collectd: Notifications have been added to the daemon. Notifications
1505 are status messages that may be associated with a data instance.
1506 * collectd: Threshold checking has been added to the daemon. This
1507 means that you can configure threshold values for each data
1508 instance. If this threshold is exceeded a notification will be
1510 * collectd: The new `FQDNLookup' option tells the daemon to use the
1511 full qualified domain name as the hostname, not just the host part
1512 es returned by `gethostname(2)'.
1513 * collectd: Support for more than one `TypesDB' file has been added.
1514 This is useful when one such file is included in a package but one
1515 wants to add custom type definitions.
1516 * collectd: The `Include' config option has been expanded to handle
1517 entire directories and shell wildcards.
1518 * collectdmon: The new `collectdmon' binary detects when collectd
1519 terminates and automatically restarts it again.
1520 * csv plugin: The CSV plugin is now able to store counter values as a
1521 rate, using the `StoreRates' configuration option.
1522 * exec plugin: Handling of notifications has been added and the
1523 ability to pass arguments to the executed programs has been added.
1524 * hddtemp plugin: The new `TranslateDevicename' option lets you
1525 disable the translation from device names to major-minor-numbers.
1526 * logfile plugin: Handling of notifications has been added.
1527 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1528 domain name lookups in this plugin.
1529 * perl plugin: Many internal changes added support for handling multiple
1530 threads making the plugin reasonably usable inside collectd. The API has
1531 been extended to support notifications and export global variables to
1532 Perl plugins; callbacks now have to be identified by name rather than a
1533 pointer to a subroutine. The plugin is no longer experimental.
1534 * uuid plugin: The new UUID plugin sets the hostname to an unique
1535 identifier for this host. This is meant for setups where each client
1536 may migrate to another physical host, possibly going through one or
1537 more name changes in the process. Thanks to Richard Jones from
1538 Red Hat's Emerging Technology group for this plugin.
1539 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1540 CPU, disk and network statistics about guest systems on the same
1541 physical server. Thanks to Richard Jones from Red Hat's Emerging
1542 Technology group for this plugin.
1544 2008-04-22, Version 4.2.7
1545 * build system: Improved detection of several libraries, especially if
1546 they are in non-standard paths.
1547 * build system: Portability fixes: Automatically define "_REENTRANT"
1548 if the libc expects it.
1549 * collectd: Error and warning messages have been improved.
1550 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1552 * apache plugin: Allocate new memory when reading a webpage instead of
1553 using a buffer of static size.
1554 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1556 * hddtemp plugin: Error and warning messages have been improved.
1557 * sensors plugin: Fix sensor collection for some chip types.
1559 2008-03-29, Version 4.2.6
1560 * collectd: Improved error messages when parsing the configuration.
1561 * sensors plugin: Fix temperature collection with libsensors4.
1562 * unixsock plugin: Fix mixed input and output operation on streams.
1563 * wireless plugin: Fix reading noise value.
1565 2008-03-04, Version 4.2.5
1566 * apache plugin: Improved initialization and error messages.
1567 * exec plugin: Set supplementary group IDs.
1569 + Create separate threads for reading from the socket and parsing
1570 and dispatching incoming packets. Versions prior to this may have
1571 problems in high-load situations, where the socket receive buffers
1572 overflows, resulting in gaps in the data.
1573 + Use `memcpy' when constructing/parsing a package to avoid
1574 alignment problems on weird architectures, such as Sparc.
1575 + Translate doubles to/from the x86 byte representation to ensure
1576 cross-platform compatibility.
1577 * ping plugin: Correct the handling of the `TTL' setting.
1578 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1579 * swap plugin: Reapply a patch for Solaris.
1580 * tcpconns plugin: Portability improvements.
1582 2008-01-21, Version 4.2.4
1583 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1584 the permission on the socket as documented in the manpage. Thanks to
1585 Evgeny Chukreev for fixing this issue.
1586 * collectd: The documentation has been improved.
1588 2007-12-28, Version 4.2.3
1589 * sensors plugin: Updated the plugin to build and work with version 3
1590 of the libsensors library.
1592 2007-12-15, Version 4.2.2
1593 * nginx plugin: Incorrect comparison of strings lead to a segfault
1594 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1596 * logfile plugin: The config option `Timestamp' was handled
1597 incorrectly and basically always active. Thanks to Luke Heberling
1600 2007-11-08, Version 4.2.1
1601 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1602 enabled on the host.
1603 * snmp plugin: Fix a memory leak.
1605 2007-10-27, Version 4.2.0
1606 * collectd: The new config option `Include' lets you include other
1607 configfiles and thus split up your config into smaller parts. This
1608 may be especially interesting for the snmp plugin to keep the data
1609 definitions separate from the host definitions.
1610 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1611 (number of connections, octets and packets for each service and
1612 destination). Thanks to Sebastian Harl for this plugin.
1613 * memcached plugin: The new `memcached' plugin connects to a memcached
1614 daemon process and collects statistics of this distributed caching
1615 system. Thanks to Antony Dovgal for contributing this plugin.
1616 * nginx plugin: The new `nginx' plugin reads the status page of an
1617 nginx daemon and saves the handled connections and requests.
1618 * perl plugin: Many changes, including the added `EnableDebugger'
1619 config option which lets you debug your Perl plugins more easily.
1620 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1621 be more thread-safe otherwise by locking calls to the library.
1622 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1623 correct the values returned by SNMP-agents. If a <data> block is
1624 defined as `table' the instance is now optional. The sequence number
1625 is used as the type-instance in this case. The new `InstancePrefix'
1626 option allows to add arbitrary prefixes to the type-instance.
1627 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1628 certain TCP connections and what state they're in. This can be used
1629 to see how many connections your FTP server has to handle or how
1630 many outgoing connections your mailserver has open.
1632 2008-01-11, Version 4.1.6
1633 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1634 the permission on the socket as documented in the manpage. Thanks to
1635 Evgeny Chukreev for fixing this issue.
1636 * collectd: The documentation has been improved.
1638 2007-12-27, Version 4.1.5
1639 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1641 * sensors plugin: Updated the plugin to build and work with version 3
1642 of the libsensors library.
1644 2007-11-08, Version 4.1.4
1645 * Build system: Improve detection of the rrd library, especially if
1646 it's in a non-standard location.
1647 * Build system: A bug when parsing the argument for
1648 `--with-libnetsnmp' has been fixed.
1649 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1650 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1651 a deadlock or delay when shutting down the daemon.
1652 * snmp plugin: Fix a memory leak.
1654 2007-10-24, Version 4.1.3
1655 * collectd: A build issue under Solaris has been resolved by renaming
1657 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1658 be more thread-safe otherwise by locking calls to the library.
1660 2007-09-28, Version 4.1.2
1661 * apcups plugin: Fix reporting of the `load percent' data.
1662 * wireless plugin: Correct the handling of cards returning signal and
1663 noise quality as percentage.
1664 * perl plugin: Fix a possible buffer overflow in get_module_name().
1665 * build system: Further improve the detection of libraries.
1666 * netlink plugin: Build issues under some older versions of the Linux
1667 includes (i. e. Debian Sarge) have been fixed.
1668 * snmp plugin: Fix a potential segfault when a host times out. Add
1669 support for the `timeticks' type.
1671 2007-09-12, Version 4.1.1
1672 * Build system: The detection of `libnetlink' has been improved.
1673 * collectd: The documentation has been fixed in numerous places.
1674 * exec plugin: Setting the group under which to run a program has been
1676 * collectd: The `sstrerror' function was improved to work correctly
1677 with the broken GNU version of `strerror_r'.
1678 * collectd: Write an error message to STDERR when loading of a plugin
1680 * apcups plugin: Fix the `types' used to submit the values: They still
1681 has an `apcups_' prefix which doesn't work anymore.
1682 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1683 whatever the client thinks is `now'..
1685 2007-09-01, Version 4.1.0
1686 * Build system: The build system has been changed to automatically
1687 disable all plugins, which are missing dependencies. The dependency
1688 checking has been removed from the plugins themselves to remove
1690 * Flexible interval: The interval of collected data is now sent along
1691 with the data itself over the network, so that the interval-settings
1692 of server and clients no longer needs to match.
1693 * netlink plugin: The new `netlink' plugin connects to the Linux
1694 kernel using a netlink socket and uses it to query information about
1695 interfaces, qdiscs and classes.
1696 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1697 to not block data collection.
1698 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1699 network devices, such as switches, routers, thermometers, rack
1700 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1702 * unixsock plugin: Added the `LISTVAL' command.
1703 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1704 of music played with xmms.
1706 2007-09-28, Version 4.0.9
1707 * apcups plugin: Fix reporting of the `load percent' data.
1708 * wireless plugin: Correct the handling of cards returning signal and
1709 noise quality as percentage.
1710 * perl plugin: Fix a possible buffer overflow in get_module_name().
1712 2007-09-12, Version 4.0.8
1713 * collectd: The `sstrerror' function was improved to work correctly
1714 with the broken GNU version of `strerror_r'.
1715 * collectd: Write an error message to STDERR when loading of a plugin
1717 * apcups plugin: Fix the `types' used to submit the values: They still
1718 has an `apcups_' prefix which doesn't work anymore.
1719 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1720 whatever the client thinks is `now'..
1722 2007-08-26, Version 4.0.7
1723 * documentation: Some typos have been fixed and some information has
1725 * build system: Many fixes for detecting libraries in unusual places,
1726 such as on RedHat systems. The affected libraries are `libcurl',
1727 `libmysql', and `libupsclient'.
1728 * network plugin: Allow the `Port' option to be specified as a number
1729 (i. e. without quotes).
1730 * nut plugin: A fix allows linking the nut plugin against
1731 libupsclient, version >= 2.2.0.
1732 * processes plugin: Fix a potential segmentation fault.
1734 2007-07-30, Version 4.0.6
1735 * sensors plugin: Fix the ignorelist functionality: Only the `type
1736 instance' was used to match against the list, but the documentation
1737 told otherwise. This release fixes the code, so it complies with the
1739 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1740 configuration messages will end up in the logging facility.
1741 * conrtib/fedora: The contributed specfile for Fedora has been
1744 2007-07-05, Version 4.0.5
1745 * Portability: More fixes for OpenBSD have been included.
1747 2007-06-24, Version 4.0.4
1748 * cpu plugin: Fixed the Solaris code.
1749 * dns plugin: Fixed a build issue for OpenBSD.
1750 * interface plugin: Fixed the Solaris code.
1751 * load plugin: Fixed the alternative `/proc' Linux code.
1752 * memory plugin: Fixed the Solaris code.
1753 * oconfig: Don't require `-lfl' anymore.
1755 2007-06-19, Version 4.0.3
1756 * cpu plugin: Fix the Darwin / Mac OS X code.
1757 * ping plugin: Use the return value of `getpid', not its address.
1758 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1759 initialized correctly.
1760 * configure: Added `--with-nan-emulation' to aid cross compilation.
1762 2007-06-12, Version 4.0.2
1763 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1764 they're given in numerically form.
1766 2007-06-07, Version 4.0.1
1767 * iptables plugin: A bug in the configuration routine has been fixed.
1768 Setting a comment in the configfile will no longer cause a
1771 2007-06-03, Version 4.0.0
1772 * collectd: The plugin-infrastructure has been changed to allow for
1773 more types of plugins, namely `write' and `log' plugins.
1774 * collectd: The read-function has been changed to read many plugins in
1775 parallel, using threads. Thus, plugins generally need to use
1776 thread-safe functions from now on.
1777 * collectd: The '-t' command line options allows to perform syntax tests
1778 of the configuration file and exit immediately.
1779 * csv plugin: The new `csv' plugin handles output to `comma separated
1781 * rrdtool plugin: The new `rrdtool' plugin handles output to
1782 RRD-files. Data can be cached to combine multiple updates into one
1783 write to increase IO-performance.
1784 * network plugin: The new `network' plugin handles IO via the network.
1785 It implements a different, much more extensible protocol which can
1786 combine many values in one packet, decreasing the number of UDP-
1787 packets being sent. It can read from and send to the network and
1788 with the appropriate configuration even forward packets to other
1790 * unixsock plugin: The new `unixsock' plugin provides an interface to
1791 communicate with the daemon while it is running. Right now the
1792 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1794 * perl plugin: The new `perl' plugin allows you to write extensions
1795 for collectd in the scripting-language Perl.
1796 * logfile plugin: The new `logfile' plugin writes logmessages to files
1797 or STDOUT or STDERR.
1798 * syslog plugin: The new `syslog' plugin sends logmessages to the
1799 system's syslog daemon.
1800 * entropy plugin: The new `entropy' plugin collects the amount of
1801 entropy currently being available to the system.
1802 * exec plugin: The new `exec' plugin forks child processes and reads
1803 back values provided by the forked processes.
1804 * iptables plugin: The new `iptables' plugin reads counters from
1805 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1807 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1808 to Peter Holik for contributing this plugin.
1809 * nut plugin: The new `nut' plugin connects the upsd of the `network
1810 ups tools' and reads information about the connected UPS.
1811 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1812 connections) field was added by Florent Monbillard.
1813 * collectd-nagios: The new `collectd-nagios' binary queries values
1814 from collectd, parses them and exits according to Nagios-standards.
1815 * manpages: The manpages have been improved a lot.
1817 2007-09-28, Version 3.11.7
1818 * wireless plugin: Correct the handling of cards returning signal and
1819 noise quality as percentage.
1821 2007-08-31, Version 3.11.6
1822 * processes plugin: Fix a potential segmentation fault.
1824 2007-05-29, Version 3.11.5
1825 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1826 * ntpd plugin: Fix a potential buffer overflow.
1827 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1828 were accounted as `zombies'.
1830 2007-04-10, Version 3.11.4
1831 * dns plugin: Change the order of includes to make the plugin compile
1834 2007-03-30, Version 3.11.3
1835 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1836 of the unused `COLLECT_KSTAT'.
1838 2007-02-11, Version 3.11.2
1839 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1840 NULL-pointer may have been passed to `printf' which causes a
1841 segfault with some libcs.
1843 2007-02-10, Version 3.11.1
1844 * df plugin: Some wrong defines have been fixed so the plugin works
1845 under Solaris again.
1846 * dns plugin: The usage of a struct has been fixed to work with
1848 * processes plugin: Some missing defines have been added so the plugin
1849 compiles cleanly under FreeBSD and presumably other UNIXes.
1851 2006-12-22, Version 3.11.0
1852 * collectd: The new command line option `-P' makes it easier for
1853 distributors to change the location of PID-files.
1854 * collectd: The daemon shuts down faster now which makes it easier to
1855 write init.d-scripts for it.
1856 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1857 caused problems every now and then.
1858 * df plugin: New config options allow to ignore certain mountpoints,
1859 filesystem types or devices.
1860 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1861 and interprets it. It collects traffic as well as qtype, opcode and
1863 * email plugin: Sebastian Harl has contributed this plugin which
1864 counts received mails in categories (e. g. ham, spam, virus), spam
1865 score (as given by SpamAssassin) and check types.
1866 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1867 uses `mbmon' to gather information from sensors on the motherboard.
1868 * processes plugin: Collect detailed statistics for configured
1869 processes, that's process and thread count, CPU usage, resident
1870 segment size and pagefaults.
1871 * multimeter plugin: Peter Holik contributed a new plugin which
1872 queries multimeters.
1873 * sensors plugin: Lubos Stanek has put much effort into improving this
1874 plugin, including `extended naming', collection of voltage values
1875 and the possibility to ignore certain values.
1877 2006-12-21, Version 3.10.4
1878 * Max Kellermann has identified a bug in the server routine: When
1879 opening a socket fails the daemon will (re)try opening the socket in
1880 an endless loop, ultimately leading to a `EMFILE' error.
1882 2006-11-04, Version 3.10.3
1883 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1884 ntpd's reply was sent in more than one packet, the buffer size was
1885 calculated incorrectly, resulting in the reading of uninitialized or
1888 2006-11-01, Version 3.10.2
1889 * The sample config file has been improved.
1890 * Errors in the manpages have been corrected.
1891 * The ping-plugin now adds hosts during initialization, not during
1892 startup. This speeds up startup when no network connectivity is
1893 available. Also, the hosts are being added later when the network is
1895 * Improved BSD-support for the df-plugin.
1896 * Fixed syntax errors in the swap-plugin for Mac OS X.
1897 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1899 * Don't disable the mysql-plugin if connecting to the database fails
1900 during initialization. Instead, try again in increasing intervals.
1902 2006-07-19, Version 3.10.1
1903 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1904 the apcups cannot be reached, unconnected sockets will pile up and
1905 eventually lead to `Too many open files' errors.
1907 2006-07-09, Version 3.10.0
1908 * The `disk' plugin has been ported to Darwin.
1909 * The `battery' plugin should work on many Apple computers now.
1910 * The `traffic' plugin can now ignore certain interfaces. Also,
1911 statistics for sent/received packets and errors have been added.
1912 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1913 to Anthony Gialluca for contributing this plugin and providing me
1914 with a test environment :)
1915 * A plugin for monitoring an NTP instance and the local clock drift
1918 2006-06-25, Version 3.9.4
1919 * The Solaris code in the `swap' plugin has been changed to reflect
1920 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1922 * The debugging system has been fixed to work with the Sun libc.
1923 * When built without librrd the variable `operating_mode' could be
1924 uninitialized. Thanks to David Elliot for reporting the bug.
1926 2006-06-01, Version 3.9.3
1927 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1928 operating systems also profit from the changes, but I wasn't able to
1930 * Changed the build system to find the netinet-includes under FreeBSD
1931 and therefore successfully build the `liboping' library there.
1933 2006-05-09, Version 3.9.2
1934 * Applied a patch to the `liboping' library. Due to a bug in the
1935 sequence checking the `ping' plugin stopped working after
1936 approximately 7.6 days.
1938 2006-05-09, Version 3.8.5
1939 * Applied a patch to the `liboping' library. Due to a bug in the
1940 sequence checking the `ping' plugin stopped working after
1941 approximately 7.6 days.
1943 2006-04-21, Version 3.9.1
1944 * Build issues with Solaris and possible other architectures have been
1946 * Problems when building the `apache'-plugin without `libcurl' have
1948 * A bug in the `ping' plugin has been fixed. Sorry folks.
1950 2006-04-02, Version 3.9.0
1951 * A plugin to monitor the Apache webserver has been added.
1952 <http://httpd.apache.org/>
1953 * A plugin to collect statistics about virtual servers using VServer.
1954 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1956 * A plugin for wireless LAN cards has been added. It monitors signal
1957 strength, link quality and noise ratio..
1958 * A plugin for Apple hardware sensors has been added.
1959 * An option to compile collectd with different `step' and `heartbeat'
1960 settings has been added. The size of RRAs is no longer static but
1961 calculated based on the settings for `step' and `width'.
1962 * The `ping' plugin can now be configured to use a certain TTL.
1963 * A plugin to monitor the hardware sensors of Apple computers has been
1965 * The plugins `cpu', `memory', `processes' and `traffic' have been
1966 ported to Mach/Darwin (Mac OS X).
1967 * The `log mode' has been contributed by Christophe Kalt. It writes
1968 the data into text files rather than RRD files.
1970 2006-04-09, Version 3.8.4
1971 * Applied patch by Vincent Stehlé which improves the disk-name
1972 resolution in the `hddtemp' plugin for Linux systems.
1974 2006-04-02, Version 3.8.3
1975 * Applied a patch by James Byers: The MySQL plugin was not working
1976 with MySQL 5.0.2 or later.
1978 2006-03-14, Version 3.8.2
1979 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1980 the GNU libc, because it points to `/etc/fstab' rather than
1983 2006-03-13, Version 3.8.1
1984 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1985 * Fixes in the debian `postinst' and `init.d' scripts.
1987 2006-03-09, Version 3.8.0
1988 * The `ping' plugin no longer uses `libping' but a self written
1989 library named `liboping'. With this library it's possible to ping
1990 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1992 2006-02-18, Version 3.7.2
1993 * A simple bug in the `battery' plugin has been fixed. It should now
1994 work with ACPI based batteries as well. Thanks to Sebastian for
1996 * Fixing a bug that prevented collectd to be built without librrd.
1997 Thanks to Werner Heuser for reporting it.
1999 2006-02-04, Version 3.7.1
2000 * The new network code has been improved to build with older versions
2002 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2003 to Tommie Gannert for this patch.
2005 2006-01-30, Version 3.7.0
2006 * The `battery' plugin has been added. It collects information about
2008 * The MySQL plugin has been improved: It now writes two more RRD
2009 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2010 * The `cpufreq' plugin now reads another file since the file it did
2011 read so far causes much overhead in the kernel. Also, you need root
2012 to read the old file, but not to read the new one.
2013 * The `hddtemp' plugin can now be configured to connect to another
2014 address and/or port than localhost.
2015 * The `df' plugin now prefers `statvfs' over `statfs'.
2016 * The network code has been rewritten. collectd now supports unicast
2017 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2018 be set in the configfile.
2020 2006-01-24, Version 3.6.2
2021 * Due to a bug in the configfile handling collectd wouldn't start in
2022 client mode. This released fixes this.
2024 2006-01-20, Version 3.6.1
2025 * Due to a bug in `configure.in' all modules and the binary were
2026 linked against `libmysqlclient'. This issue is solved by this
2029 2006-01-17, Version 3.6.0
2030 * A config file has been added. This allows for loading only specific
2032 * A `df' plugin has been added.
2033 * A `mysql' plugin has been added.
2034 * The `ping' plugin doesn't entirely give up hope when a socket error
2035 occurred, but will back of and increase the intervals between tries.
2037 2006-01-21, Version 3.5.2
2038 * Fixed yet another bug in the signal handling.. Stupid typo..
2039 * Improved the ping plugin to not give up on socket errors (backport
2042 2005-12-18, Version 3.5.1
2043 * The PID-file is now deleted correctly when shutting down the daemon.
2044 * SIGINT and SIGTERM are now handled correctly.
2046 2005-12-16, Version 3.5.0 (Revision 326)
2047 * A bug in the `load' module under Solaris has been fixed.
2048 * The `users' module has been contributed by Sebastian Harl. It counts
2049 currently logged in users.
2050 * The CPU module now works under FreeBSD without the use of
2051 `libstatgrab', however SMP support is missing.
2052 * The default directories for the RRD files and the PID file now
2053 depend on the compile time setting of `localstatedir'.
2055 2005-11-15, Version 3.4.0 (Revision 236)
2056 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2057 from gentoo's bugzilla for writing the patch.
2058 * The build dependency for librrd has been removed. Binaries built
2059 without librrd are client-only and will multicast their value as
2060 with the `-c' argument.
2061 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2062 * The newly introduced `-f' switch prevents daemon initialization
2063 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2064 Barcellos for this patch.
2066 2005-11-04, Version 3.3.0 (Revision 216)
2067 * New modules have been added:
2068 - `serial', for monitoring traffic on the serial interfaces
2069 - `nfs', for graphing NFS procedure calls
2070 - `tape', traffic from/to tape devices
2071 * The memory.rrd now accepts more than 4Gig of memory.
2073 2005-10-26, Version 3.2.0 (Revision 200)
2074 * Support for graphing the processes has been added (thanks to Lyonel
2076 * If reading from hddtemp fails collectd will increase the time
2077 between polls up to one day.
2078 * The init.d files have been improved.
2079 * Problems with the spec file have been fixed.
2081 2005-10-16, Version 3.1.0 (Revision 194)
2082 * Added the `setsid' syscall to the startup code.
2083 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2085 2005-09-30, Version 3.0.0 (Revision 184)
2086 * The ability to send/receive data to/from the network (think
2087 multicast) has been added.
2088 * Modules have been split up into shared libraries can be loaded at
2089 runtime. The biggest advantage is that the core program doesn't need
2090 to be linked against an external library.
2091 * A patch by George Kargiotakis has been applied: It fixes the sensors
2092 behaviour then more than one sensor is being queried.
2094 2005-09-16, Version 2.1.0 (Revision 172)
2095 * A module for swap statistics has been added.
2097 2005-09-09, Version 2.0.0 (Revision 135)
2098 * Filenames can no longer be configured at program startup. The only
2099 options as of this version are the directory and ping hosts.
2100 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2101 Soft-IRQ statistics are added to `System'.
2102 * Diskstats now collect read and write bytes, not sectors.
2103 * Ping statistics can now be collected for more than one host. There
2104 is no default any more: If no host is given no host will be pinged.
2105 * A self-written patch for libping has been applied so it builds
2108 2005-09-01, Version 1.8.1 (Revision 123)
2109 * Much improved configure-script: libraries and features may now be
2111 * More detailed warnings/error messages when RRD update fails.
2113 2005-08-29, Version 1.8.0:
2114 * Support for collecting disk statistics under Solaris.
2116 2005-08-25, Version 1.7.0:
2117 * Support for libstatgrab[1] for load, memory usage and network
2118 traffic. CPU- and disk-usage are not (yet) supported, since
2119 libstatgrab returns insufficient information. I will contact the
2121 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2122 aren't necessarily counted linear which is now handled correctly.
2123 [1]: http://www.i-scream.org/libstatgrab/
2125 2005-08-21, Version 1.6.0:
2126 * Basic support for Solaris: System load and cpu-usage can be
2127 collected under Solaris, too. Other stats will follow later.
2128 * Many fixes in the autoconf-script
2129 * Collection/Museum scripts have been added under contrib/museum
2130 * collectd may now be started in unprivileged mode, though ping
2131 statistics will not work.
2133 2005-07-17, Version 1.5.1:
2134 * Diskstats-RRDs now use major/minor for naming. Some systems have
2135 weird strings as disk-names..
2137 2005-07-17, Version 1.5:
2138 * A new module, diskstats, has been added. It collects information
2139 about the disks and partitions.
2141 2005-07-11, Version 1.4.2:
2142 * The meminfo module has been changed to work with more platforms
2143 and/or kernel versions.
2145 2005-07-10, Version 1.4.1: Correct traffic stats
2146 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2147 forgot to correct when I changed that module.
2149 2005-07-09, Version 1.4: More traffic stats
2150 * Traffic is now collected for all interfaces that can be found
2151 * Temperature-statistics are read from lm-sensors if available
2153 2005-07-08, Version 1.3: CPU stats
2154 * Collecting CPU statistics now
2156 2005-07-12, Version 1.2: Using syslog
2157 * collectd is now using the syslog facility to report errors, warnings
2159 * The default directory is now /var/db/collectd
2161 2005-07-10, Version 1.1: Minor changes
2162 * Nothing really useful to say ;)
2164 2005-07-09, Version 1.0: Initial Version
2165 * The following modules are provided:
