1018 This way the “GETVAL” command of the UnixSock plugin doesn't return
1019 old, no longer valid values when this happens. Thanks to Andrés J.
1021 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1022 to follow redirects. Thanks to Joey Hess for reporting this bug.

1048 for many fixes and providing a build system for many platforms,
1049 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1050 providing an OpenBSD system.
1051 * collectd: Two bugs with the threshold checking have been fixed. The
1052 first one prevented thresholds to be checked at all, the second one
1053 caused wrong behavior with the persistency option. Thanks to Andrés
1054 J. Díaz for fixing these problems.
1055 * collectd: Handling of the `Include' configuration option has been

1072 * liboping: A patch to comply with strict aliasing rules has been
1074 * timediff match: Fix a typo: The match was registered with a wrong
1075 name which prevented this match to be used as documented. Thanks to
1076 Bruno Prémont for finding this problem.
1077 * bind plugin: Fix collection of the cached RR sets. The number of RR
1078 sets currently in the cache was collected as a counter value, which
1079 is nonsense. Thanks to Bruno Prémont for implementing this.
1080 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1081 primarily BSDs, don't take it well and crash.
1082 * oracle plugin: Portability to 64 bit systems has been improved.
1083 * postgresql plugin: The default configuration has been improved.
1084 * rrdtool plugin: Fix a possible race condition: If the network plugin

1120 example for native OpenBSD support, has been added. Thanks to Simon
1121 Kuhnle for the patch.
1122 * csv plugin: Make it possible to write values to STDOUT instead of
1123 files. This is meant for testing purposes mostly. The output written
1124 to STDOUT is compatible with the exec plugin. Thanks to Doug
1125 MacEachern for the patch.
1126 * curl plugin: This new plugin can be used to read web pages and parse
1127 them using the same mechanism that's used in the tail plugin.
1128 * dbi plugin: This new plugin allows you to connect to a variety of
1129 relational databases and use SQL to gather custom statistics from
1130 it. It is similar to the already existing PostgreSQL plugin but uses
1131 libdbi to communicate with the database(s).
1132 * interface plugin: Use the ignorelist framework when selecting /
1133 ignoring interfaces. This allows one to use regular expressions to
1134 select interfaces, too.

1154 * postgresql plugin: The preferred configuration syntax has been
1155 updated to be in line with the syntax used by the new dbi and oracle
1156 plugins. The compatibility code for the old syntax is present.
1157 Support for the new `Result' blocks and the interval parameter has
1159 * processes plugin: Stacksize and virtual memory usage statistics have
1160 been added. Portability fixes.
1161 * rrdcached plugin: This new plugin uses the (still in development)
1162 RRD accelerator daemon, rrdcached. This daemon works very similar to
1163 the original rrdtool plugin of collectd, but adds some more nice

1182 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1184 * rrdtool plugin: Fix a possible race condition: If the network plugin
1185 is initialized and dispatches a value before the rrdtool plugin is
1186 initialized, the daemon may crash.
1187 * memory plugin: Fix a potential problem under Solaris.
1189 2009-02-22, Version 4.5.3

1201 2009-01-02, Version 4.5.2
1202 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1203 file may be in both locations, especially when the database was
1204 installed in a non-standard path. Thanks to Dusty Doris for
1206 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1207 Solaris, in the configure script automatically.
1208 * build system, tcpconns plugin: Check for `kvm_nlist' and
1209 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1210 library with similar functions to the BSD variant, but doesn't
1211 provide these necessary functions.
1212 * collectd.conf(5): Various fixes and clarifications.
1213 * collectd: Remove a GNUism (unnamed unions), thus improving

1218 * filecount plugin: Fix an off-by-one error. This error may cause a
1220 * network plugin: Fix the handling of `type' in the network protocol.
1221 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1222 much larger buffer. This caused the `type' to be transferred much
1223 more often than necessary. In some cases, e. g. the `cpu' and
1224 `cpufreq' plugins being used at the same time, data may be corrupted
1225 in those files. Thanks to Bruno Prémont for debugging and reporting
1227 * processes plugin: Fix a possible segmentation fault when specifying
1228 invalid configuration options.
1229 * unixsock plugin: Make sure the initialization function is run only
1230 once. This resolves a file descriptor leak under systems which run
1231 the initialization more than once, such as Solaris.
1233 2008-10-16, Version 4.5.1
1234 * build system: Change `--enable-<plugin>' to abort with an error if
1235 dependencies are not met. Thanks to Bruno Prémont for the patch.
1236 Also, the poisoning of various string functions has been restricted
1238 * collectd: Fix a memory leak in the global value cache. With every
1239 *missing* value a couple of bytes would be leaked. Another memory
1240 leak in the configuration handling code has been fixed. Thanks to
1241 Niraj Tolia for reporting these issues.
1242 * collectd: Fix an off-by-one error in the ignorelist functionality.
1243 When using regular expressions, the last character would be missing,
1244 possibly matching differently from what one would expect.
1245 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1247 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1248 Linzberger for reporting the bug.
1249 * iptables plugin: Fix an off-by-one error. If a string was just one
1250 character too long, it was truncated instead of reporting an error.
1251 * network plugin: Fix a memory leak in the configuration handling
1252 code. Thanks to Niraj Tolia for reporting this issue.
1253 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

1257 leaks. Thanks to ``Admin'' for reporting these bugs.
1258 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1260 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1261 problems with some `libc's. Thanks to Matthias Lay for reporting the

1273 X desktop using the structure defined in the `Desktop Notification
1275 * notify_email plugin: This new plugin sends out notifications via
1276 email, using the `esmtp' library.
1277 * onewire plugin: The new experimental(!) onewire plugin reads values,
1278 such as temperatures, from sensors connected to the computer via the
1280 * perl plugin: Improved synchronized access to internal data structures
1281 and fixed a possible dead-lock.
1282 * perl plugin: Added the ability to flush certain identifiers and marked
1283 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1285 * perl plugin: Added the ability to configure Perl plugins.

1293 using Linux ACPI thermal zone data.
1295 2009-01-02, Version 4.4.5
1296 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1297 file may be in both locations, especially when the database was
1298 installed in a non-standard path. Thanks to Dusty Doris for
1300 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1301 Solaris, in the configure script automatically.

1460 * ping plugin: Correct the handling of the `TTL' setting.
1461 * swap plugin: Reapply a patch for Solaris.
1462 * tcpconns plugin: Portability improvements.
1464 2008-02-18, Version 4.3.0
1465 * collectd: Notifications have been added to the daemon. Notifications
1466 are status messages that may be associated with a data instance.
1467 * collectd: Threshold checking has been added to the daemon. This
1468 means that you can configure threshold values for each data
1469 instance. If this threshold is exceeded a notification will be
1471 * collectd: The new `FQDNLookup' option tells the daemon to use the
1472 full qualified domain name as the hostname, not just the host part
1473 es returned by `gethostname(2)'.
1474 * collectd: Support for more than one `TypesDB' file has been added.
1475 This is useful when one such file is included in a package but one
1476 wants to add custom type definitions.
1477 * collectd: The `Include' config option has been expanded to handle
1478 entire directories and shell wildcards.
1479 * collectdmon: The new `collectdmon' binary detects when collectd
1480 terminates and automatically restarts it again.
1481 * csv plugin: The CSV plugin is now able to store counter values as a
1482 rate, using the `StoreRates' configuration option.
1483 * exec plugin: Handling of notifications has been added and the
1484 ability to pass arguments to the executed programs has been added.
1485 * hddtemp plugin: The new `TranslateDevicename' option lets you
1486 disable the translation from device names to major-minor-numbers.
1487 * logfile plugin: Handling of notifications has been added.
1488 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1489 domain name lookups in this plugin.
1490 * perl plugin: Many internal changes added support for handling multiple
1491 threads making the plugin reasonably usable inside collectd. The API has
1492 been extended to support notifications and export global variables to
1493 Perl plugins; callbacks now have to be identified by name rather than a
1494 pointer to a subroutine. The plugin is no longer experimental.
1495 * uuid plugin: The new UUID plugin sets the hostname to an unique
1496 identifier for this host. This is meant for setups where each client
1497 may migrate to another physical host, possibly going through one or
1498 more name changes in the process. Thanks to Richard Jones from
1499 Red Hat's Emerging Technology group for this plugin.
1500 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1501 CPU, disk and network statistics about guest systems on the same
1502 physical server. Thanks to Richard Jones from Red Hat's Emerging
1503 Technology group for this plugin.
1505 2008-04-22, Version 4.2.7
1506 * build system: Improved detection of several libraries, especially if
1507 they are in non-standard paths.
1508 * build system: Portability fixes: Automatically define "_REENTRANT"
1509 if the libc expects it.
1510 * collectd: Error and warning messages have been improved.
1511 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1513 * apache plugin: Allocate new memory when reading a webpage instead of
1514 using a buffer of static size.
1515 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1517 * hddtemp plugin: Error and warning messages have been improved.
1518 * sensors plugin: Fix sensor collection for some chip types.
1520 2008-03-29, Version 4.2.6
1521 * collectd: Improved error messages when parsing the configuration.
1522 * sensors plugin: Fix temperature collection with libsensors4.
1523 * unixsock plugin: Fix mixed input and output operation on streams.
1524 * wireless plugin: Fix reading noise value.
1526 2008-03-04, Version 4.2.5
1527 * apache plugin: Improved initialization and error messages.
1528 * exec plugin: Set supplementary group IDs.
1530 + Create separate threads for reading from the socket and parsing
1531 and dispatching incoming packets. Versions prior to this may have
1532 problems in high-load situations, where the socket receive buffers
1533 overflows, resulting in gaps in the data.
1534 + Use `memcpy' when constructing/parsing a package to avoid
1535 alignment problems on weird architectures, such as Sparc.
1536 + Translate doubles to/from the x86 byte representation to ensure
1537 cross-platform compatibility.
1538 * ping plugin: Correct the handling of the `TTL' setting.
1539 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1540 * swap plugin: Reapply a patch for Solaris.
1541 * tcpconns plugin: Portability improvements.
1543 2008-01-21, Version 4.2.4
1544 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1545 the permission on the socket as documented in the manpage. Thanks to
1546 Evgeny Chukreev for fixing this issue.
1547 * collectd: The documentation has been improved.
1549 2007-12-28, Version 4.2.3
1550 * sensors plugin: Updated the plugin to build and work with version 3
1551 of the libsensors library.
1553 2007-12-15, Version 4.2.2
1554 * nginx plugin: Incorrect comparison of strings lead to a segfault
1555 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1557 * logfile plugin: The config option `Timestamp' was handled
1558 incorrectly and basically always active. Thanks to Luke Heberling
1561 2007-11-08, Version 4.2.1
1562 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1563 enabled on the host.
1564 * snmp plugin: Fix a memory leak.
1566 2007-10-27, Version 4.2.0
1567 * collectd: The new config option `Include' lets you include other
1568 configfiles and thus split up your config into smaller parts. This
1569 may be especially interesting for the snmp plugin to keep the data
1570 definitions separate from the host definitions.
1571 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1572 (number of connections, octets and packets for each service and
1573 destination). Thanks to Sebastian Harl for this plugin.
1574 * memcached plugin: The new `memcached' plugin connects to a memcached
1575 daemon process and collects statistics of this distributed caching
1576 system. Thanks to Antony Dovgal for contributing this plugin.
1577 * nginx plugin: The new `nginx' plugin reads the status page of an
1578 nginx daemon and saves the handled connections and requests.
1579 * perl plugin: Many changes, including the added `EnableDebugger'
1580 config option which lets you debug your Perl plugins more easily.
1581 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1582 be more thread-safe otherwise by locking calls to the library.
1583 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1584 correct the values returned by SNMP-agents. If a <data> block is
1585 defined as `table' the instance is now optional. The sequence number
1586 is used as the type-instance in this case. The new `InstancePrefix'
1587 option allows to add arbitrary prefixes to the type-instance.
1588 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1589 certain TCP connections and what state they're in. This can be used
1590 to see how many connections your FTP server has to handle or how
1591 many outgoing connections your mailserver has open.
1593 2008-01-11, Version 4.1.6
1594 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1595 the permission on the socket as documented in the manpage. Thanks to
1596 Evgeny Chukreev for fixing this issue.
1597 * collectd: The documentation has been improved.
1599 2007-12-27, Version 4.1.5
1600 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1602 * sensors plugin: Updated the plugin to build and work with version 3
1603 of the libsensors library.
1605 2007-11-08, Version 4.1.4
1606 * Build system: Improve detection of the rrd library, especially if
1607 it's in a non-standard location.
1608 * Build system: A bug when parsing the argument for
1609 `--with-libnetsnmp' has been fixed.
1610 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1611 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1612 a deadlock or delay when shutting down the daemon.
1613 * snmp plugin: Fix a memory leak.
1615 2007-10-24, Version 4.1.3
1616 * collectd: A build issue under Solaris has been resolved by renaming
1618 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1619 be more thread-safe otherwise by locking calls to the library.
1621 2007-09-28, Version 4.1.2
1622 * apcups plugin: Fix reporting of the `load percent' data.
1623 * wireless plugin: Correct the handling of cards returning signal and
1624 noise quality as percentage.
1625 * perl plugin: Fix a possible buffer overflow in get_module_name().
1626 * build system: Further improve the detection of libraries.
1627 * netlink plugin: Build issues under some older versions of the Linux
1628 includes (i. e. Debian Sarge) have been fixed.
1629 * snmp plugin: Fix a potential segfault when a host times out. Add
1630 support for the `timeticks' type.
1632 2007-09-12, Version 4.1.1
1633 * Build system: The detection of `libnetlink' has been improved.
1634 * collectd: The documentation has been fixed in numerous places.
1635 * exec plugin: Setting the group under which to run a program has been
1637 * collectd: The `sstrerror' function was improved to work correctly
1638 with the broken GNU version of `strerror_r'.
1639 * collectd: Write an error message to STDERR when loading of a plugin
1641 * apcups plugin: Fix the `types' used to submit the values: They still
1642 has an `apcups_' prefix which doesn't work anymore.
1643 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1644 whatever the client thinks is `now'..
1646 2007-09-01, Version 4.1.0
1647 * Build system: The build system has been changed to automatically
1648 disable all plugins, which are missing dependencies. The dependency
1649 checking has been removed from the plugins themselves to remove
1651 * Flexible interval: The interval of collected data is now sent along
1652 with the data itself over the network, so that the interval-settings
1653 of server and clients no longer needs to match.
1654 * netlink plugin: The new `netlink' plugin connects to the Linux
1655 kernel using a netlink socket and uses it to query information about
1656 interfaces, qdiscs and classes.
1657 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1658 to not block data collection.
1659 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1660 network devices, such as switches, routers, thermometers, rack
1661 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1663 * unixsock plugin: Added the `LISTVAL' command.
1664 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1665 of music played with xmms.
1667 2007-09-28, Version 4.0.9
1668 * apcups plugin: Fix reporting of the `load percent' data.
1669 * wireless plugin: Correct the handling of cards returning signal and
1670 noise quality as percentage.
1671 * perl plugin: Fix a possible buffer overflow in get_module_name().
1673 2007-09-12, Version 4.0.8
1674 * collectd: The `sstrerror' function was improved to work correctly
1675 with the broken GNU version of `strerror_r'.
1676 * collectd: Write an error message to STDERR when loading of a plugin
1678 * apcups plugin: Fix the `types' used to submit the values: They still
1679 has an `apcups_' prefix which doesn't work anymore.
1680 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1681 whatever the client thinks is `now'..
1683 2007-08-26, Version 4.0.7
1684 * documentation: Some typos have been fixed and some information has
1686 * build system: Many fixes for detecting libraries in unusual places,
1687 such as on RedHat systems. The affected libraries are `libcurl',
1688 `libmysql', and `libupsclient'.
1689 * network plugin: Allow the `Port' option to be specified as a number
1690 (i. e. without quotes).
1691 * nut plugin: A fix allows linking the nut plugin against
1692 libupsclient, version >= 2.2.0.
1693 * processes plugin: Fix a potential segmentation fault.
1695 2007-07-30, Version 4.0.6
1696 * sensors plugin: Fix the ignorelist functionality: Only the `type
1697 instance' was used to match against the list, but the documentation
1698 told otherwise. This release fixes the code, so it complies with the
1700 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1701 configuration messages will end up in the logging facility.
1702 * conrtib/fedora: The contributed specfile for Fedora has been
1705 2007-07-05, Version 4.0.5
1706 * Portability: More fixes for OpenBSD have been included.
1708 2007-06-24, Version 4.0.4
1709 * cpu plugin: Fixed the Solaris code.
1710 * dns plugin: Fixed a build issue for OpenBSD.
1711 * interface plugin: Fixed the Solaris code.
1712 * load plugin: Fixed the alternative `/proc' Linux code.
1713 * memory plugin: Fixed the Solaris code.
1714 * oconfig: Don't require `-lfl' anymore.
1716 2007-06-19, Version 4.0.3
1717 * cpu plugin: Fix the Darwin / Mac OS X code.
1718 * ping plugin: Use the return value of `getpid', not its address.
1719 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1720 initialized correctly.
1721 * configure: Added `--with-nan-emulation' to aid cross compilation.
1723 2007-06-12, Version 4.0.2
1724 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1725 they're given in numerically form.
1727 2007-06-07, Version 4.0.1
1728 * iptables plugin: A bug in the configuration routine has been fixed.
1729 Setting a comment in the configfile will no longer cause a
1732 2007-06-03, Version 4.0.0
1733 * collectd: The plugin-infrastructure has been changed to allow for
1734 more types of plugins, namely `write' and `log' plugins.
1735 * collectd: The read-function has been changed to read many plugins in
1736 parallel, using threads. Thus, plugins generally need to use
1737 thread-safe functions from now on.
1738 * collectd: The '-t' command line options allows to perform syntax tests
1739 of the configuration file and exit immediately.
1740 * csv plugin: The new `csv' plugin handles output to `comma separated
1742 * rrdtool plugin: The new `rrdtool' plugin handles output to
1743 RRD-files. Data can be cached to combine multiple updates into one
1744 write to increase IO-performance.
1745 * network plugin: The new `network' plugin handles IO via the network.
1746 It implements a different, much more extensible protocol which can
1747 combine many values in one packet, decreasing the number of UDP-
1748 packets being sent. It can read from and send to the network and
1749 with the appropriate configuration even forward packets to other
1751 * unixsock plugin: The new `unixsock' plugin provides an interface to
1752 communicate with the daemon while it is running. Right now the
1753 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1755 * perl plugin: The new `perl' plugin allows you to write extensions
1756 for collectd in the scripting-language Perl.
1757 * logfile plugin: The new `logfile' plugin writes logmessages to files
1758 or STDOUT or STDERR.
1759 * syslog plugin: The new `syslog' plugin sends logmessages to the
1760 system's syslog daemon.
1761 * entropy plugin: The new `entropy' plugin collects the amount of
1762 entropy currently being available to the system.
1763 * exec plugin: The new `exec' plugin forks child processes and reads
1764 back values provided by the forked processes.
1765 * iptables plugin: The new `iptables' plugin reads counters from
1766 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1768 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1769 to Peter Holik for contributing this plugin.
1770 * nut plugin: The new `nut' plugin connects the upsd of the `network
1771 ups tools' and reads information about the connected UPS.
1772 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1773 connections) field was added by Florent Monbillard.
1774 * collectd-nagios: The new `collectd-nagios' binary queries values
1775 from collectd, parses them and exits according to Nagios-standards.
1776 * manpages: The manpages have been improved a lot.
1778 2007-09-28, Version 3.11.7
1779 * wireless plugin: Correct the handling of cards returning signal and
1780 noise quality as percentage.
1782 2007-08-31, Version 3.11.6
1783 * processes plugin: Fix a potential segmentation fault.
1785 2007-05-29, Version 3.11.5
1786 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1787 * ntpd plugin: Fix a potential buffer overflow.
1788 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1789 were accounted as `zombies'.
1791 2007-04-10, Version 3.11.4
1792 * dns plugin: Change the order of includes to make the plugin compile
1795 2007-03-30, Version 3.11.3
1796 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1797 of the unused `COLLECT_KSTAT'.
1799 2007-02-11, Version 3.11.2
1800 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1801 NULL-pointer may have been passed to `printf' which causes a
1802 segfault with some libcs.
1804 2007-02-10, Version 3.11.1
1805 * df plugin: Some wrong defines have been fixed so the plugin works
1806 under Solaris again.
1807 * dns plugin: The usage of a struct has been fixed to work with
1809 * processes plugin: Some missing defines have been added so the plugin
1810 compiles cleanly under FreeBSD and presumably other UNIXes.
1812 2006-12-22, Version 3.11.0
1813 * collectd: The new command line option `-P' makes it easier for
1814 distributors to change the location of PID-files.
1815 * collectd: The daemon shuts down faster now which makes it easier to
1816 write init.d-scripts for it.
1817 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1818 caused problems every now and then.
1819 * df plugin: New config options allow to ignore certain mountpoints,
1820 filesystem types or devices.
1821 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1822 and interprets it. It collects traffic as well as qtype, opcode and
1824 * email plugin: Sebastian Harl has contributed this plugin which
1825 counts received mails in categories (e. g. ham, spam, virus), spam
1826 score (as given by SpamAssassin) and check types.
1827 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1828 uses `mbmon' to gather information from sensors on the motherboard.
1829 * processes plugin: Collect detailed statistics for configured
1830 processes, that's process and thread count, CPU usage, resident
1831 segment size and pagefaults.
1832 * multimeter plugin: Peter Holik contributed a new plugin which
1833 queries multimeters.
1834 * sensors plugin: Lubos Stanek has put much effort into improving this
1835 plugin, including `extended naming', collection of voltage values
1836 and the possibility to ignore certain values.
1838 2006-12-21, Version 3.10.4
1839 * Max Kellermann has identified a bug in the server routine: When
1840 opening a socket fails the daemon will (re)try opening the socket in
1841 an endless loop, ultimately leading to a `EMFILE' error.
1843 2006-11-04, Version 3.10.3
1844 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1845 ntpd's reply was sent in more than one packet, the buffer size was
1846 calculated incorrectly, resulting in the reading of uninitialized or
1849 2006-11-01, Version 3.10.2
1850 * The sample config file has been improved.
1851 * Errors in the manpages have been corrected.
1852 * The ping-plugin now adds hosts during initialization, not during
1853 startup. This speeds up startup when no network connectivity is
1854 available. Also, the hosts are being added later when the network is
1856 * Improved BSD-support for the df-plugin.
1857 * Fixed syntax errors in the swap-plugin for Mac OS X.
1858 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1860 * Don't disable the mysql-plugin if connecting to the database fails
1861 during initialization. Instead, try again in increasing intervals.
1863 2006-07-19, Version 3.10.1
1864 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1865 the apcups cannot be reached, unconnected sockets will pile up and
1866 eventually lead to `Too many open files' errors.
1868 2006-07-09, Version 3.10.0
1869 * The `disk' plugin has been ported to Darwin.
1870 * The `battery' plugin should work on many Apple computers now.
1871 * The `traffic' plugin can now ignore certain interfaces. Also,
1872 statistics for sent/received packets and errors have been added.
1873 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1874 to Anthony Gialluca for contributing this plugin and providing me
1875 with a test environment :)
1876 * A plugin for monitoring an NTP instance and the local clock drift
1879 2006-06-25, Version 3.9.4
1880 * The Solaris code in the `swap' plugin has been changed to reflect
1881 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1883 * The debugging system has been fixed to work with the Sun libc.
1884 * When built without librrd the variable `operating_mode' could be
1885 uninitialized. Thanks to David Elliot for reporting the bug.
1887 2006-06-01, Version 3.9.3
1888 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1889 operating systems also profit from the changes, but I wasn't able to
1891 * Changed the build system to find the netinet-includes under FreeBSD
1892 and therefore successfully build the `liboping' library there.
1894 2006-05-09, Version 3.9.2
1895 * Applied a patch to the `liboping' library. Due to a bug in the
1896 sequence checking the `ping' plugin stopped working after
1897 approximately 7.6 days.
1899 2006-05-09, Version 3.8.5
1900 * Applied a patch to the `liboping' library. Due to a bug in the
1901 sequence checking the `ping' plugin stopped working after
1902 approximately 7.6 days.
1904 2006-04-21, Version 3.9.1
1905 * Build issues with Solaris and possible other architectures have been
1907 * Problems when building the `apache'-plugin without `libcurl' have
1909 * A bug in the `ping' plugin has been fixed. Sorry folks.
1911 2006-04-02, Version 3.9.0
1912 * A plugin to monitor the Apache webserver has been added.
1913 <http://httpd.apache.org/>
1914 * A plugin to collect statistics about virtual servers using VServer.
1915 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1917 * A plugin for wireless LAN cards has been added. It monitors signal
1918 strength, link quality and noise ratio..
1919 * A plugin for Apple hardware sensors has been added.
1920 * An option to compile collectd with different `step' and `heartbeat'
1921 settings has been added. The size of RRAs is no longer static but
1922 calculated based on the settings for `step' and `width'.
1923 * The `ping' plugin can now be configured to use a certain TTL.
1924 * A plugin to monitor the hardware sensors of Apple computers has been
1926 * The plugins `cpu', `memory', `processes' and `traffic' have been
1927 ported to Mach/Darwin (Mac OS X).
1928 * The `log mode' has been contributed by Christophe Kalt. It writes
1929 the data into text files rather than RRD files.
1931 2006-04-09, Version 3.8.4
1932 * Applied patch by Vincent Stehlé which improves the disk-name
1933 resolution in the `hddtemp' plugin for Linux systems.
1935 2006-04-02, Version 3.8.3
1936 * Applied a patch by James Byers: The MySQL plugin was not working
1937 with MySQL 5.0.2 or later.
1939 2006-03-14, Version 3.8.2
1940 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1941 the GNU libc, because it points to `/etc/fstab' rather than
1944 2006-03-13, Version 3.8.1
1945 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1946 * Fixes in the debian `postinst' and `init.d' scripts.
1948 2006-03-09, Version 3.8.0
1949 * The `ping' plugin no longer uses `libping' but a self written
1950 library named `liboping'. With this library it's possible to ping
1951 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1953 2006-02-18, Version 3.7.2
1954 * A simple bug in the `battery' plugin has been fixed. It should now
1955 work with ACPI based batteries as well. Thanks to Sebastian for
1957 * Fixing a bug that prevented collectd to be built without librrd.
1958 Thanks to Werner Heuser for reporting it.
1960 2006-02-04, Version 3.7.1
1961 * The new network code has been improved to build with older versions
1963 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1964 to Tommie Gannert for this patch.
1966 2006-01-30, Version 3.7.0
1967 * The `battery' plugin has been added. It collects information about
1969 * The MySQL plugin has been improved: It now writes two more RRD
1970 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1971 * The `cpufreq' plugin now reads another file since the file it did
1972 read so far causes much overhead in the kernel. Also, you need root
1973 to read the old file, but not to read the new one.
1974 * The `hddtemp' plugin can now be configured to connect to another
1975 address and/or port than localhost.
1976 * The `df' plugin now prefers `statvfs' over `statfs'.
1977 * The network code has been rewritten. collectd now supports unicast
1978 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1979 be set in the configfile.
1981 2006-01-24, Version 3.6.2
1982 * Due to a bug in the configfile handling collectd wouldn't start in
1983 client mode. This released fixes this.
1985 2006-01-20, Version 3.6.1
1986 * Due to a bug in `configure.in' all modules and the binary were
1987 linked against `libmysqlclient'. This issue is solved by this
1990 2006-01-17, Version 3.6.0
1991 * A config file has been added. This allows for loading only specific
1993 * A `df' plugin has been added.
1994 * A `mysql' plugin has been added.
1995 * The `ping' plugin doesn't entirely give up hope when a socket error
1996 occurred, but will back of and increase the intervals between tries.
1998 2006-01-21, Version 3.5.2
1999 * Fixed yet another bug in the signal handling.. Stupid typo..
2000 * Improved the ping plugin to not give up on socket errors (backport
2003 2005-12-18, Version 3.5.1
2004 * The PID-file is now deleted correctly when shutting down the daemon.
2005 * SIGINT and SIGTERM are now handled correctly.
2007 2005-12-16, Version 3.5.0 (Revision 326)
2008 * A bug in the `load' module under Solaris has been fixed.
2009 * The `users' module has been contributed by Sebastian Harl. It counts
2010 currently logged in users.
2011 * The CPU module now works under FreeBSD without the use of
2012 `libstatgrab', however SMP support is missing.
2013 * The default directories for the RRD files and the PID file now
2014 depend on the compile time setting of `localstatedir'.
2016 2005-11-15, Version 3.4.0 (Revision 236)
2017 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2018 from gentoo's bugzilla for writing the patch.
2019 * The build dependency for librrd has been removed. Binaries built
2020 without librrd are client-only and will multicast their value as
2021 with the `-c' argument.
2022 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2023 * The newly introduced `-f' switch prevents daemon initialization
2024 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2025 Barcellos for this patch.
2027 2005-11-04, Version 3.3.0 (Revision 216)
2028 * New modules have been added:
2029 - `serial', for monitoring traffic on the serial interfaces
2030 - `nfs', for graphing NFS procedure calls
2031 - `tape', traffic from/to tape devices
2032 * The memory.rrd now accepts more than 4Gig of memory.
2034 2005-10-26, Version 3.2.0 (Revision 200)
2035 * Support for graphing the processes has been added (thanks to Lyonel
2037 * If reading from hddtemp fails collectd will increase the time
2038 between polls up to one day.
2039 * The init.d files have been improved.
2040 * Problems with the spec file have been fixed.
2042 2005-10-16, Version 3.1.0 (Revision 194)
2043 * Added the `setsid' syscall to the startup code.
2044 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2046 2005-09-30, Version 3.0.0 (Revision 184)
2047 * The ability to send/receive data to/from the network (think
2048 multicast) has been added.
2049 * Modules have been split up into shared libraries can be loaded at
2050 runtime. The biggest advantage is that the core program doesn't need
2051 to be linked against an external library.
2052 * A patch by George Kargiotakis has been applied: It fixes the sensors
2053 behaviour then more than one sensor is being queried.
2055 2005-09-16, Version 2.1.0 (Revision 172)
2056 * A module for swap statistics has been added.
2058 2005-09-09, Version 2.0.0 (Revision 135)
2059 * Filenames can no longer be configured at program startup. The only
2060 options as of this version are the directory and ping hosts.
2061 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2062 Soft-IRQ statistics are added to `System'.
2063 * Diskstats now collect read and write bytes, not sectors.
2064 * Ping statistics can now be collected for more than one host. There
2065 is no default any more: If no host is given no host will be pinged.
2066 * A self-written patch for libping has been applied so it builds
2069 2005-09-01, Version 1.8.1 (Revision 123)
2070 * Much improved configure-script: libraries and features may now be
2072 * More detailed warnings/error messages when RRD update fails.
2074 2005-08-29, Version 1.8.0:
2075 * Support for collecting disk statistics under Solaris.
2077 2005-08-25, Version 1.7.0:
2078 * Support for libstatgrab[1] for load, memory usage and network
2079 traffic. CPU- and disk-usage are not (yet) supported, since
2080 libstatgrab returns insufficient information. I will contact the
2082 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2083 aren't necessarily counted linear which is now handled correctly.
2084 [1]: http://www.i-scream.org/libstatgrab/
2086 2005-08-21, Version 1.6.0:
2087 * Basic support for Solaris: System load and cpu-usage can be
2088 collected under Solaris, too. Other stats will follow later.
2089 * Many fixes in the autoconf-script
2090 * Collection/Museum scripts have been added under contrib/museum
2091 * collectd may now be started in unprivileged mode, though ping
2092 statistics will not work.
2094 2005-07-17, Version 1.5.1:
2095 * Diskstats-RRDs now use major/minor for naming. Some systems have
2096 weird strings as disk-names..
2098 2005-07-17, Version 1.5:
2099 * A new module, diskstats, has been added. It collects information
2100 about the disks and partitions.
2102 2005-07-11, Version 1.4.2:
2103 * The meminfo module has been changed to work with more platforms
2104 and/or kernel versions.
2106 2005-07-10, Version 1.4.1: Correct traffic stats
2107 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2108 forgot to correct when I changed that module.
2110 2005-07-09, Version 1.4: More traffic stats
2111 * Traffic is now collected for all interfaces that can be found
2112 * Temperature-statistics are read from lm-sensors if available
2114 2005-07-08, Version 1.3: CPU stats
2115 * Collecting CPU statistics now
2117 2005-07-12, Version 1.2: Using syslog
2118 * collectd is now using the syslog facility to report errors, warnings
2120 * The default directory is now /var/db/collectd
2122 2005-07-10, Version 1.1: Minor changes
2123 * Nothing really useful to say ;)
2125 2005-07-09, Version 1.0: Initial Version
2126 * The following modules are provided:
