1036 This way the “GETVAL” command of the UnixSock plugin doesn't return
1037 old, no longer valid values when this happens. Thanks to Andrés J.
1039 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1040 to follow redirects. Thanks to Joey Hess for reporting this bug.

1066 for many fixes and providing a build system for many platforms,
1067 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1068 providing an OpenBSD system.
1069 * collectd: Two bugs with the threshold checking have been fixed. The
1070 first one prevented thresholds to be checked at all, the second one
1071 caused wrong behavior with the persistency option. Thanks to Andrés
1072 J. Díaz for fixing these problems.
1073 * collectd: Handling of the `Include' configuration option has been
1075 * battery plugin: Don't complain about a missing directory every

1090 * liboping: A patch to comply with strict aliasing rules has been
1092 * timediff match: Fix a typo: The match was registered with a wrong
1093 name which prevented this match to be used as documented. Thanks to
1094 Bruno Prémont for finding this problem.
1095 * bind plugin: Fix collection of the cached RR sets. The number of RR
1096 sets currently in the cache was collected as a counter value, which
1097 is nonsense. Thanks to Bruno Prémont for implementing this.
1098 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1099 primarily BSDs, don't take it well and crash.
1100 * oracle plugin: Portability to 64 bit systems has been improved.
1101 * postgresql plugin: The default configuration has been improved.
1102 * rrdtool plugin: Fix a possible race condition: If the network plugin

1138 example for native OpenBSD support, has been added. Thanks to Simon
1139 Kuhnle for the patch.
1140 * csv plugin: Make it possible to write values to STDOUT instead of
1141 files. This is meant for testing purposes mostly. The output written
1142 to STDOUT is compatible with the exec plugin. Thanks to Doug
1143 MacEachern for the patch.
1144 * curl plugin: This new plugin can be used to read web pages and parse
1145 them using the same mechanism that's used in the tail plugin.
1146 * dbi plugin: This new plugin allows you to connect to a variety of
1147 relational databases and use SQL to gather custom statistics from
1148 it. It is similar to the already existing PostgreSQL plugin but uses
1149 libdbi to communicate with the database(s).
1150 * interface plugin: Use the ignorelist framework when selecting /
1151 ignoring interfaces. This allows one to use regular expressions to
1152 select interfaces, too.

1177 * processes plugin: Stacksize and virtual memory usage statistics have
1178 been added. Portability fixes.
1179 * rrdcached plugin: This new plugin uses the (still in development)
1180 RRD accelerator daemon, rrdcached. This daemon works very similar to
1181 the original rrdtool plugin of collectd, but adds some more nice
1183 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1186 2009-05-09, Version 4.5.4
1187 * Build system, various plugins: Many build fixes for FreeBSD,

1200 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1202 * rrdtool plugin: Fix a possible race condition: If the network plugin
1203 is initialized and dispatches a value before the rrdtool plugin is
1204 initialized, the daemon may crash.
1205 * memory plugin: Fix a potential problem under Solaris.
1207 2009-02-22, Version 4.5.3

1217 code. Thanks to "thated" for reporting this.
1219 2009-01-02, Version 4.5.2
1220 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1221 file may be in both locations, especially when the database was
1222 installed in a non-standard path. Thanks to Dusty Doris for
1224 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1225 Solaris, in the configure script automatically.
1226 * build system, tcpconns plugin: Check for `kvm_nlist' and
1227 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1228 library with similar functions to the BSD variant, but doesn't
1229 provide these necessary functions.
1230 * collectd.conf(5): Various fixes and clarifications.
1231 * collectd: Remove a GNUism (unnamed unions), thus improving

1236 * filecount plugin: Fix an off-by-one error. This error may cause a
1238 * network plugin: Fix the handling of `type' in the network protocol.
1239 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1240 much larger buffer. This caused the `type' to be transferred much
1241 more often than necessary. In some cases, e. g. the `cpu' and
1242 `cpufreq' plugins being used at the same time, data may be corrupted
1243 in those files. Thanks to Bruno Prémont for debugging and reporting
1245 * processes plugin: Fix a possible segmentation fault when specifying
1246 invalid configuration options.
1247 * unixsock plugin: Make sure the initialization function is run only
1248 once. This resolves a file descriptor leak under systems which run
1249 the initialization more than once, such as Solaris.
1251 2008-10-16, Version 4.5.1
1252 * build system: Change `--enable-<plugin>' to abort with an error if
1253 dependencies are not met. Thanks to Bruno Prémont for the patch.
1254 Also, the poisoning of various string functions has been restricted
1256 * collectd: Fix a memory leak in the global value cache. With every
1257 *missing* value a couple of bytes would be leaked. Another memory
1258 leak in the configuration handling code has been fixed. Thanks to
1259 Niraj Tolia for reporting these issues.
1260 * collectd: Fix an off-by-one error in the ignorelist functionality.
1261 When using regular expressions, the last character would be missing,
1262 possibly matching differently from what one would expect.
1263 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1265 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1266 Linzberger for reporting the bug.
1267 * iptables plugin: Fix an off-by-one error. If a string was just one
1268 character too long, it was truncated instead of reporting an error.
1269 * network plugin: Fix a memory leak in the configuration handling
1270 code. Thanks to Niraj Tolia for reporting this issue.
1271 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1272 * postgresql plugin: Don't reopen connection during reinitialization.
1273 This fixes a bug under Solaris and potentially other platforms.

1275 leaks. Thanks to ``Admin'' for reporting these bugs.
1276 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1278 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1279 problems with some `libc's. Thanks to Matthias Lay for reporting the
1282 2008-09-04, Version 4.5.0
1283 * collectd: Added the ability to flush certain identifiers.

1291 X desktop using the structure defined in the `Desktop Notification
1293 * notify_email plugin: This new plugin sends out notifications via
1294 email, using the `esmtp' library.
1295 * onewire plugin: The new experimental(!) onewire plugin reads values,
1296 such as temperatures, from sensors connected to the computer via the
1298 * perl plugin: Improved synchronized access to internal data structures
1299 and fixed a possible dead-lock.
1300 * perl plugin: Added the ability to flush certain identifiers and marked
1301 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1303 * perl plugin: Added the ability to configure Perl plugins.

1311 using Linux ACPI thermal zone data.
1313 2009-01-02, Version 4.4.5
1314 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1315 file may be in both locations, especially when the database was
1316 installed in a non-standard path. Thanks to Dusty Doris for
1318 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1319 Solaris, in the configure script automatically.

1324 * network plugin: Fix the handling of `type' in the network protocol.
1325 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1326 much larger buffer. This caused the `type' to be transferred much
1327 more often than necessary. In some cases, e. g. the `cpu' and

1397 exec plugins. This command can be used to force a plugin (or all) to
1398 flush its values to disk.
1399 * collectd: Thresholds can now be configured to apply to one data
1400 source only, making it possible to configure different thresholds
1401 for each data source.

1460 * sensors plugin: Fix sensor collection for some chip types.
1462 2008-03-29, Version 4.3.2
1463 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1464 `Persist' threshold options.
1465 * collectd: Fix handling of missing values in the global value cache.
1466 * collectd: Improved error messages when parsing the configuration.
1467 * sensors plugin: Fix temperature collection with libsensors4.
1468 * unixsock plugin: Fix mixed input and output operation on streams.
1469 * wireless plugin: Fix reading noise value.
1471 2008-03-05, Version 4.3.1
1472 * exec plugin: Set supplementary group IDs.
1474 + Use `memcpy' when constructing/parsing a package to avoid
1475 alignment problems on weird architectures, such as Sparc.
1476 + Translate doubles to/from the x86 byte representation to ensure
1477 cross-platform compatibility.
1478 * ping plugin: Correct the handling of the `TTL' setting.
1479 * swap plugin: Reapply a patch for Solaris.
1480 * tcpconns plugin: Portability improvements.
1482 2008-02-18, Version 4.3.0
1483 * collectd: Notifications have been added to the daemon. Notifications
1484 are status messages that may be associated with a data instance.
1485 * collectd: Threshold checking has been added to the daemon. This
1486 means that you can configure threshold values for each data
1487 instance. If this threshold is exceeded a notification will be
1489 * collectd: The new `FQDNLookup' option tells the daemon to use the
1490 full qualified domain name as the hostname, not just the host part
1491 es returned by `gethostname(2)'.
1492 * collectd: Support for more than one `TypesDB' file has been added.
1493 This is useful when one such file is included in a package but one
1494 wants to add custom type definitions.
1495 * collectd: The `Include' config option has been expanded to handle
1496 entire directories and shell wildcards.
1497 * collectdmon: The new `collectdmon' binary detects when collectd
1498 terminates and automatically restarts it again.
1499 * csv plugin: The CSV plugin is now able to store counter values as a
1500 rate, using the `StoreRates' configuration option.
1501 * exec plugin: Handling of notifications has been added and the
1502 ability to pass arguments to the executed programs has been added.
1503 * hddtemp plugin: The new `TranslateDevicename' option lets you
1504 disable the translation from device names to major-minor-numbers.
1505 * logfile plugin: Handling of notifications has been added.
1506 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1507 domain name lookups in this plugin.
1508 * perl plugin: Many internal changes added support for handling multiple
1509 threads making the plugin reasonably usable inside collectd. The API has
1510 been extended to support notifications and export global variables to
1511 Perl plugins; callbacks now have to be identified by name rather than a
1512 pointer to a subroutine. The plugin is no longer experimental.
1513 * uuid plugin: The new UUID plugin sets the hostname to an unique
1514 identifier for this host. This is meant for setups where each client
1515 may migrate to another physical host, possibly going through one or
1516 more name changes in the process. Thanks to Richard Jones from
1517 Red Hat's Emerging Technology group for this plugin.
1518 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1519 CPU, disk and network statistics about guest systems on the same
1520 physical server. Thanks to Richard Jones from Red Hat's Emerging
1521 Technology group for this plugin.
1523 2008-04-22, Version 4.2.7
1524 * build system: Improved detection of several libraries, especially if
1525 they are in non-standard paths.
1526 * build system: Portability fixes: Automatically define "_REENTRANT"
1527 if the libc expects it.
1528 * collectd: Error and warning messages have been improved.
1529 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1531 * apache plugin: Allocate new memory when reading a webpage instead of
1532 using a buffer of static size.
1533 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1535 * hddtemp plugin: Error and warning messages have been improved.
1536 * sensors plugin: Fix sensor collection for some chip types.
1538 2008-03-29, Version 4.2.6
1539 * collectd: Improved error messages when parsing the configuration.
1540 * sensors plugin: Fix temperature collection with libsensors4.
1541 * unixsock plugin: Fix mixed input and output operation on streams.
1542 * wireless plugin: Fix reading noise value.
1544 2008-03-04, Version 4.2.5
1545 * apache plugin: Improved initialization and error messages.
1546 * exec plugin: Set supplementary group IDs.
1548 + Create separate threads for reading from the socket and parsing
1549 and dispatching incoming packets. Versions prior to this may have
1550 problems in high-load situations, where the socket receive buffers
1551 overflows, resulting in gaps in the data.
1552 + Use `memcpy' when constructing/parsing a package to avoid
1553 alignment problems on weird architectures, such as Sparc.
1554 + Translate doubles to/from the x86 byte representation to ensure
1555 cross-platform compatibility.
1556 * ping plugin: Correct the handling of the `TTL' setting.
1557 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1558 * swap plugin: Reapply a patch for Solaris.
1559 * tcpconns plugin: Portability improvements.
1561 2008-01-21, Version 4.2.4
1562 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1563 the permission on the socket as documented in the manpage. Thanks to
1564 Evgeny Chukreev for fixing this issue.
1565 * collectd: The documentation has been improved.
1567 2007-12-28, Version 4.2.3
1568 * sensors plugin: Updated the plugin to build and work with version 3
1569 of the libsensors library.
1571 2007-12-15, Version 4.2.2
1572 * nginx plugin: Incorrect comparison of strings lead to a segfault
1573 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1575 * logfile plugin: The config option `Timestamp' was handled
1576 incorrectly and basically always active. Thanks to Luke Heberling
1579 2007-11-08, Version 4.2.1
1580 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1581 enabled on the host.
1582 * snmp plugin: Fix a memory leak.
1584 2007-10-27, Version 4.2.0
1585 * collectd: The new config option `Include' lets you include other
1586 configfiles and thus split up your config into smaller parts. This
1587 may be especially interesting for the snmp plugin to keep the data
1588 definitions separate from the host definitions.
1589 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1590 (number of connections, octets and packets for each service and
1591 destination). Thanks to Sebastian Harl for this plugin.
1592 * memcached plugin: The new `memcached' plugin connects to a memcached
1593 daemon process and collects statistics of this distributed caching
1594 system. Thanks to Antony Dovgal for contributing this plugin.
1595 * nginx plugin: The new `nginx' plugin reads the status page of an
1596 nginx daemon and saves the handled connections and requests.
1597 * perl plugin: Many changes, including the added `EnableDebugger'
1598 config option which lets you debug your Perl plugins more easily.
1599 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1600 be more thread-safe otherwise by locking calls to the library.
1601 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1602 correct the values returned by SNMP-agents. If a <data> block is
1603 defined as `table' the instance is now optional. The sequence number
1604 is used as the type-instance in this case. The new `InstancePrefix'
1605 option allows to add arbitrary prefixes to the type-instance.
1606 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1607 certain TCP connections and what state they're in. This can be used
1608 to see how many connections your FTP server has to handle or how
1609 many outgoing connections your mailserver has open.
1611 2008-01-11, Version 4.1.6
1612 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1613 the permission on the socket as documented in the manpage. Thanks to
1614 Evgeny Chukreev for fixing this issue.
1615 * collectd: The documentation has been improved.
1617 2007-12-27, Version 4.1.5
1618 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1620 * sensors plugin: Updated the plugin to build and work with version 3
1621 of the libsensors library.
1623 2007-11-08, Version 4.1.4
1624 * Build system: Improve detection of the rrd library, especially if
1625 it's in a non-standard location.
1626 * Build system: A bug when parsing the argument for
1627 `--with-libnetsnmp' has been fixed.
1628 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1629 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1630 a deadlock or delay when shutting down the daemon.
1631 * snmp plugin: Fix a memory leak.
1633 2007-10-24, Version 4.1.3
1634 * collectd: A build issue under Solaris has been resolved by renaming
1636 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1637 be more thread-safe otherwise by locking calls to the library.
1639 2007-09-28, Version 4.1.2
1640 * apcups plugin: Fix reporting of the `load percent' data.
1641 * wireless plugin: Correct the handling of cards returning signal and
1642 noise quality as percentage.
1643 * perl plugin: Fix a possible buffer overflow in get_module_name().
1644 * build system: Further improve the detection of libraries.
1645 * netlink plugin: Build issues under some older versions of the Linux
1646 includes (i. e. Debian Sarge) have been fixed.
1647 * snmp plugin: Fix a potential segfault when a host times out. Add
1648 support for the `timeticks' type.
1650 2007-09-12, Version 4.1.1
1651 * Build system: The detection of `libnetlink' has been improved.
1652 * collectd: The documentation has been fixed in numerous places.
1653 * exec plugin: Setting the group under which to run a program has been
1655 * collectd: The `sstrerror' function was improved to work correctly
1656 with the broken GNU version of `strerror_r'.
1657 * collectd: Write an error message to STDERR when loading of a plugin
1659 * apcups plugin: Fix the `types' used to submit the values: They still
1660 has an `apcups_' prefix which doesn't work anymore.
1661 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1662 whatever the client thinks is `now'..
1664 2007-09-01, Version 4.1.0
1665 * Build system: The build system has been changed to automatically
1666 disable all plugins, which are missing dependencies. The dependency
1667 checking has been removed from the plugins themselves to remove
1669 * Flexible interval: The interval of collected data is now sent along
1670 with the data itself over the network, so that the interval-settings
1671 of server and clients no longer needs to match.
1672 * netlink plugin: The new `netlink' plugin connects to the Linux
1673 kernel using a netlink socket and uses it to query information about
1674 interfaces, qdiscs and classes.
1675 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1676 to not block data collection.
1677 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1678 network devices, such as switches, routers, thermometers, rack
1679 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1681 * unixsock plugin: Added the `LISTVAL' command.
1682 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1683 of music played with xmms.
1685 2007-09-28, Version 4.0.9
1686 * apcups plugin: Fix reporting of the `load percent' data.
1687 * wireless plugin: Correct the handling of cards returning signal and
1688 noise quality as percentage.
1689 * perl plugin: Fix a possible buffer overflow in get_module_name().
1691 2007-09-12, Version 4.0.8
1692 * collectd: The `sstrerror' function was improved to work correctly
1693 with the broken GNU version of `strerror_r'.
1694 * collectd: Write an error message to STDERR when loading of a plugin
1696 * apcups plugin: Fix the `types' used to submit the values: They still
1697 has an `apcups_' prefix which doesn't work anymore.
1698 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1699 whatever the client thinks is `now'..
1701 2007-08-26, Version 4.0.7
1702 * documentation: Some typos have been fixed and some information has
1704 * build system: Many fixes for detecting libraries in unusual places,
1705 such as on RedHat systems. The affected libraries are `libcurl',
1706 `libmysql', and `libupsclient'.
1707 * network plugin: Allow the `Port' option to be specified as a number
1708 (i. e. without quotes).
1709 * nut plugin: A fix allows linking the nut plugin against
1710 libupsclient, version >= 2.2.0.
1711 * processes plugin: Fix a potential segmentation fault.
1713 2007-07-30, Version 4.0.6
1714 * sensors plugin: Fix the ignorelist functionality: Only the `type
1715 instance' was used to match against the list, but the documentation
1716 told otherwise. This release fixes the code, so it complies with the
1718 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1719 configuration messages will end up in the logging facility.
1720 * conrtib/fedora: The contributed specfile for Fedora has been
1723 2007-07-05, Version 4.0.5
1724 * Portability: More fixes for OpenBSD have been included.
1726 2007-06-24, Version 4.0.4
1727 * cpu plugin: Fixed the Solaris code.
1728 * dns plugin: Fixed a build issue for OpenBSD.
1729 * interface plugin: Fixed the Solaris code.
1730 * load plugin: Fixed the alternative `/proc' Linux code.
1731 * memory plugin: Fixed the Solaris code.
1732 * oconfig: Don't require `-lfl' anymore.
1734 2007-06-19, Version 4.0.3
1735 * cpu plugin: Fix the Darwin / Mac OS X code.
1736 * ping plugin: Use the return value of `getpid', not its address.
1737 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1738 initialized correctly.
1739 * configure: Added `--with-nan-emulation' to aid cross compilation.
1741 2007-06-12, Version 4.0.2
1742 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1743 they're given in numerically form.
1745 2007-06-07, Version 4.0.1
1746 * iptables plugin: A bug in the configuration routine has been fixed.
1747 Setting a comment in the configfile will no longer cause a
1750 2007-06-03, Version 4.0.0
1751 * collectd: The plugin-infrastructure has been changed to allow for
1752 more types of plugins, namely `write' and `log' plugins.
1753 * collectd: The read-function has been changed to read many plugins in
1754 parallel, using threads. Thus, plugins generally need to use
1755 thread-safe functions from now on.
1756 * collectd: The '-t' command line options allows to perform syntax tests
1757 of the configuration file and exit immediately.
1758 * csv plugin: The new `csv' plugin handles output to `comma separated
1760 * rrdtool plugin: The new `rrdtool' plugin handles output to
1761 RRD-files. Data can be cached to combine multiple updates into one
1762 write to increase IO-performance.
1763 * network plugin: The new `network' plugin handles IO via the network.
1764 It implements a different, much more extensible protocol which can
1765 combine many values in one packet, decreasing the number of UDP-
1766 packets being sent. It can read from and send to the network and
1767 with the appropriate configuration even forward packets to other
1769 * unixsock plugin: The new `unixsock' plugin provides an interface to
1770 communicate with the daemon while it is running. Right now the
1771 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1773 * perl plugin: The new `perl' plugin allows you to write extensions
1774 for collectd in the scripting-language Perl.
1775 * logfile plugin: The new `logfile' plugin writes logmessages to files
1776 or STDOUT or STDERR.
1777 * syslog plugin: The new `syslog' plugin sends logmessages to the
1778 system's syslog daemon.
1779 * entropy plugin: The new `entropy' plugin collects the amount of
1780 entropy currently being available to the system.
1781 * exec plugin: The new `exec' plugin forks child processes and reads
1782 back values provided by the forked processes.
1783 * iptables plugin: The new `iptables' plugin reads counters from
1784 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1786 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1787 to Peter Holik for contributing this plugin.
1788 * nut plugin: The new `nut' plugin connects the upsd of the `network
1789 ups tools' and reads information about the connected UPS.
1790 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1791 connections) field was added by Florent Monbillard.
1792 * collectd-nagios: The new `collectd-nagios' binary queries values
1793 from collectd, parses them and exits according to Nagios-standards.
1794 * manpages: The manpages have been improved a lot.
1796 2007-09-28, Version 3.11.7
1797 * wireless plugin: Correct the handling of cards returning signal and
1798 noise quality as percentage.
1800 2007-08-31, Version 3.11.6
1801 * processes plugin: Fix a potential segmentation fault.
1803 2007-05-29, Version 3.11.5
1804 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1805 * ntpd plugin: Fix a potential buffer overflow.
1806 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1807 were accounted as `zombies'.
1809 2007-04-10, Version 3.11.4
1810 * dns plugin: Change the order of includes to make the plugin compile
1813 2007-03-30, Version 3.11.3
1814 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1815 of the unused `COLLECT_KSTAT'.
1817 2007-02-11, Version 3.11.2
1818 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1819 NULL-pointer may have been passed to `printf' which causes a
1820 segfault with some libcs.
1822 2007-02-10, Version 3.11.1
1823 * df plugin: Some wrong defines have been fixed so the plugin works
1824 under Solaris again.
1825 * dns plugin: The usage of a struct has been fixed to work with
1827 * processes plugin: Some missing defines have been added so the plugin
1828 compiles cleanly under FreeBSD and presumably other UNIXes.
1830 2006-12-22, Version 3.11.0
1831 * collectd: The new command line option `-P' makes it easier for
1832 distributors to change the location of PID-files.
1833 * collectd: The daemon shuts down faster now which makes it easier to
1834 write init.d-scripts for it.
1835 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1836 caused problems every now and then.
1837 * df plugin: New config options allow to ignore certain mountpoints,
1838 filesystem types or devices.
1839 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1840 and interprets it. It collects traffic as well as qtype, opcode and
1842 * email plugin: Sebastian Harl has contributed this plugin which
1843 counts received mails in categories (e. g. ham, spam, virus), spam
1844 score (as given by SpamAssassin) and check types.
1845 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1846 uses `mbmon' to gather information from sensors on the motherboard.
1847 * processes plugin: Collect detailed statistics for configured
1848 processes, that's process and thread count, CPU usage, resident
1849 segment size and pagefaults.
1850 * multimeter plugin: Peter Holik contributed a new plugin which
1851 queries multimeters.
1852 * sensors plugin: Lubos Stanek has put much effort into improving this
1853 plugin, including `extended naming', collection of voltage values
1854 and the possibility to ignore certain values.
1856 2006-12-21, Version 3.10.4
1857 * Max Kellermann has identified a bug in the server routine: When
1858 opening a socket fails the daemon will (re)try opening the socket in
1859 an endless loop, ultimately leading to a `EMFILE' error.
1861 2006-11-04, Version 3.10.3
1862 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1863 ntpd's reply was sent in more than one packet, the buffer size was
1864 calculated incorrectly, resulting in the reading of uninitialized or
1867 2006-11-01, Version 3.10.2
1868 * The sample config file has been improved.
1869 * Errors in the manpages have been corrected.
1870 * The ping-plugin now adds hosts during initialization, not during
1871 startup. This speeds up startup when no network connectivity is
1872 available. Also, the hosts are being added later when the network is
1874 * Improved BSD-support for the df-plugin.
1875 * Fixed syntax errors in the swap-plugin for Mac OS X.
1876 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1878 * Don't disable the mysql-plugin if connecting to the database fails
1879 during initialization. Instead, try again in increasing intervals.
1881 2006-07-19, Version 3.10.1
1882 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1883 the apcups cannot be reached, unconnected sockets will pile up and
1884 eventually lead to `Too many open files' errors.
1886 2006-07-09, Version 3.10.0
1887 * The `disk' plugin has been ported to Darwin.
1888 * The `battery' plugin should work on many Apple computers now.
1889 * The `traffic' plugin can now ignore certain interfaces. Also,
1890 statistics for sent/received packets and errors have been added.
1891 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1892 to Anthony Gialluca for contributing this plugin and providing me
1893 with a test environment :)
1894 * A plugin for monitoring an NTP instance and the local clock drift
1897 2006-06-25, Version 3.9.4
1898 * The Solaris code in the `swap' plugin has been changed to reflect
1899 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1901 * The debugging system has been fixed to work with the Sun libc.
1902 * When built without librrd the variable `operating_mode' could be
1903 uninitialized. Thanks to David Elliot for reporting the bug.
1905 2006-06-01, Version 3.9.3
1906 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1907 operating systems also profit from the changes, but I wasn't able to
1909 * Changed the build system to find the netinet-includes under FreeBSD
1910 and therefore successfully build the `liboping' library there.
1912 2006-05-09, Version 3.9.2
1913 * Applied a patch to the `liboping' library. Due to a bug in the
1914 sequence checking the `ping' plugin stopped working after
1915 approximately 7.6 days.
1917 2006-05-09, Version 3.8.5
1918 * Applied a patch to the `liboping' library. Due to a bug in the
1919 sequence checking the `ping' plugin stopped working after
1920 approximately 7.6 days.
1922 2006-04-21, Version 3.9.1
1923 * Build issues with Solaris and possible other architectures have been
1925 * Problems when building the `apache'-plugin without `libcurl' have
1927 * A bug in the `ping' plugin has been fixed. Sorry folks.
1929 2006-04-02, Version 3.9.0
1930 * A plugin to monitor the Apache webserver has been added.
1931 <http://httpd.apache.org/>
1932 * A plugin to collect statistics about virtual servers using VServer.
1933 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1935 * A plugin for wireless LAN cards has been added. It monitors signal
1936 strength, link quality and noise ratio..
1937 * A plugin for Apple hardware sensors has been added.
1938 * An option to compile collectd with different `step' and `heartbeat'
1939 settings has been added. The size of RRAs is no longer static but
1940 calculated based on the settings for `step' and `width'.
1941 * The `ping' plugin can now be configured to use a certain TTL.
1942 * A plugin to monitor the hardware sensors of Apple computers has been
1944 * The plugins `cpu', `memory', `processes' and `traffic' have been
1945 ported to Mach/Darwin (Mac OS X).
1946 * The `log mode' has been contributed by Christophe Kalt. It writes
1947 the data into text files rather than RRD files.
1949 2006-04-09, Version 3.8.4
1950 * Applied patch by Vincent Stehlé which improves the disk-name
1951 resolution in the `hddtemp' plugin for Linux systems.
1953 2006-04-02, Version 3.8.3
1954 * Applied a patch by James Byers: The MySQL plugin was not working
1955 with MySQL 5.0.2 or later.
1957 2006-03-14, Version 3.8.2
1958 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1959 the GNU libc, because it points to `/etc/fstab' rather than
1962 2006-03-13, Version 3.8.1
1963 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1964 * Fixes in the debian `postinst' and `init.d' scripts.
1966 2006-03-09, Version 3.8.0
1967 * The `ping' plugin no longer uses `libping' but a self written
1968 library named `liboping'. With this library it's possible to ping
1969 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1971 2006-02-18, Version 3.7.2
1972 * A simple bug in the `battery' plugin has been fixed. It should now
1973 work with ACPI based batteries as well. Thanks to Sebastian for
1975 * Fixing a bug that prevented collectd to be built without librrd.
1976 Thanks to Werner Heuser for reporting it.
1978 2006-02-04, Version 3.7.1
1979 * The new network code has been improved to build with older versions
1981 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1982 to Tommie Gannert for this patch.
1984 2006-01-30, Version 3.7.0
1985 * The `battery' plugin has been added. It collects information about
1987 * The MySQL plugin has been improved: It now writes two more RRD
1988 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1989 * The `cpufreq' plugin now reads another file since the file it did
1990 read so far causes much overhead in the kernel. Also, you need root
1991 to read the old file, but not to read the new one.
1992 * The `hddtemp' plugin can now be configured to connect to another
1993 address and/or port than localhost.
1994 * The `df' plugin now prefers `statvfs' over `statfs'.
1995 * The network code has been rewritten. collectd now supports unicast
1996 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1997 be set in the configfile.
1999 2006-01-24, Version 3.6.2
2000 * Due to a bug in the configfile handling collectd wouldn't start in
2001 client mode. This released fixes this.
2003 2006-01-20, Version 3.6.1
2004 * Due to a bug in `configure.in' all modules and the binary were
2005 linked against `libmysqlclient'. This issue is solved by this
2008 2006-01-17, Version 3.6.0
2009 * A config file has been added. This allows for loading only specific
2011 * A `df' plugin has been added.
2012 * A `mysql' plugin has been added.
2013 * The `ping' plugin doesn't entirely give up hope when a socket error
2014 occurred, but will back of and increase the intervals between tries.
2016 2006-01-21, Version 3.5.2
2017 * Fixed yet another bug in the signal handling.. Stupid typo..
2018 * Improved the ping plugin to not give up on socket errors (backport
2021 2005-12-18, Version 3.5.1
2022 * The PID-file is now deleted correctly when shutting down the daemon.
2023 * SIGINT and SIGTERM are now handled correctly.
2025 2005-12-16, Version 3.5.0 (Revision 326)
2026 * A bug in the `load' module under Solaris has been fixed.
2027 * The `users' module has been contributed by Sebastian Harl. It counts
2028 currently logged in users.
2029 * The CPU module now works under FreeBSD without the use of
2030 `libstatgrab', however SMP support is missing.
2031 * The default directories for the RRD files and the PID file now
2032 depend on the compile time setting of `localstatedir'.
2034 2005-11-15, Version 3.4.0 (Revision 236)
2035 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2036 from gentoo's bugzilla for writing the patch.
2037 * The build dependency for librrd has been removed. Binaries built
2038 without librrd are client-only and will multicast their value as
2039 with the `-c' argument.
2040 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2041 * The newly introduced `-f' switch prevents daemon initialization
2042 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2043 Barcellos for this patch.
2045 2005-11-04, Version 3.3.0 (Revision 216)
2046 * New modules have been added:
2047 - `serial', for monitoring traffic on the serial interfaces
2048 - `nfs', for graphing NFS procedure calls
2049 - `tape', traffic from/to tape devices
2050 * The memory.rrd now accepts more than 4Gig of memory.
2052 2005-10-26, Version 3.2.0 (Revision 200)
2053 * Support for graphing the processes has been added (thanks to Lyonel

2056 between polls up to one day.
2057 * The init.d files have been improved.
2058 * Problems with the spec file have been fixed.
2060 2005-10-16, Version 3.1.0 (Revision 194)
2061 * Added the `setsid' syscall to the startup code.
2062 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2064 2005-09-30, Version 3.0.0 (Revision 184)
2065 * The ability to send/receive data to/from the network (think
2066 multicast) has been added.
2067 * Modules have been split up into shared libraries can be loaded at
2068 runtime. The biggest advantage is that the core program doesn't need
2069 to be linked against an external library.
2070 * A patch by George Kargiotakis has been applied: It fixes the sensors
2071 behaviour then more than one sensor is being queried.
2073 2005-09-16, Version 2.1.0 (Revision 172)
2074 * A module for swap statistics has been added.
2076 2005-09-09, Version 2.0.0 (Revision 135)
2077 * Filenames can no longer be configured at program startup. The only
2078 options as of this version are the directory and ping hosts.
2079 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2080 Soft-IRQ statistics are added to `System'.
2081 * Diskstats now collect read and write bytes, not sectors.
2082 * Ping statistics can now be collected for more than one host. There
2083 is no default any more: If no host is given no host will be pinged.
2084 * A self-written patch for libping has been applied so it builds
2087 2005-09-01, Version 1.8.1 (Revision 123)
2088 * Much improved configure-script: libraries and features may now be
2090 * More detailed warnings/error messages when RRD update fails.
2092 2005-08-29, Version 1.8.0:
2093 * Support for collecting disk statistics under Solaris.
2095 2005-08-25, Version 1.7.0:
2096 * Support for libstatgrab[1] for load, memory usage and network
2097 traffic. CPU- and disk-usage are not (yet) supported, since
2098 libstatgrab returns insufficient information. I will contact the
2100 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2101 aren't necessarily counted linear which is now handled correctly.
2102 [1]: http://www.i-scream.org/libstatgrab/
2104 2005-08-21, Version 1.6.0:
2105 * Basic support for Solaris: System load and cpu-usage can be
2106 collected under Solaris, too. Other stats will follow later.
2107 * Many fixes in the autoconf-script
2108 * Collection/Museum scripts have been added under contrib/museum
2109 * collectd may now be started in unprivileged mode, though ping
2110 statistics will not work.
2112 2005-07-17, Version 1.5.1:
2113 * Diskstats-RRDs now use major/minor for naming. Some systems have
2114 weird strings as disk-names..
2116 2005-07-17, Version 1.5:
2117 * A new module, diskstats, has been added. It collects information
2118 about the disks and partitions.
2120 2005-07-11, Version 1.4.2:
2121 * The meminfo module has been changed to work with more platforms
2122 and/or kernel versions.
2124 2005-07-10, Version 1.4.1: Correct traffic stats
2125 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2126 forgot to correct when I changed that module.
2128 2005-07-09, Version 1.4: More traffic stats
2129 * Traffic is now collected for all interfaces that can be found
2130 * Temperature-statistics are read from lm-sensors if available
2132 2005-07-08, Version 1.3: CPU stats
2133 * Collecting CPU statistics now
2135 2005-07-12, Version 1.2: Using syslog
2136 * collectd is now using the syslog facility to report errors, warnings
2138 * The default directory is now /var/db/collectd
2140 2005-07-10, Version 1.1: Minor changes
2141 * Nothing really useful to say ;)
2143 2005-07-09, Version 1.0: Initial Version
2144 * The following modules are provided:
