1007 first one prevented thresholds to be checked at all, the second one
1008 caused wrong behavior with the persistency option. Thanks to Andrés
1009 J. Díaz for fixing these problems.
1010 * collectd: Handling of the `Include' configuration option has been
1012 * rrdtool plugin: Make sure initialization is run only once. This
1013 resolves problems under Solaris and potentially other systems.
1014 Thanks to Amit Gupta for reporting this bug.
1015 * java plugin: Make it possible to use dots ('.') instead of slashes
1016 ('/') as the class separator. Thanks to Randy Rizun for pointing

1065 2009-09-10, Version 4.6.5
1066 * collectd: Remove old values when a cache entry is marked as missing.
1067 This way the “GETVAL” command of the UnixSock plugin doesn't return
1068 old, no longer valid values when this happens. Thanks to Andrés J.
1070 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1071 to follow redirects. Thanks to Joey Hess for reporting this bug.

1097 for many fixes and providing a build system for many platforms,
1098 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1099 providing an OpenBSD system.
1100 * collectd: Two bugs with the threshold checking have been fixed. The
1101 first one prevented thresholds to be checked at all, the second one
1102 caused wrong behavior with the persistency option. Thanks to Andrés
1103 J. Díaz for fixing these problems.

1120 * filter subsystem: Allow `Chains' without default targets.
1121 * liboping: A patch to comply with strict aliasing rules has been
1123 * timediff match: Fix a typo: The match was registered with a wrong
1124 name which prevented this match to be used as documented. Thanks to
1125 Bruno Prémont for finding this problem.
1126 * bind plugin: Fix collection of the cached RR sets. The number of RR
1127 sets currently in the cache was collected as a counter value, which
1128 is nonsense. Thanks to Bruno Prémont for implementing this.
1129 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1130 primarily BSDs, don't take it well and crash.
1131 * oracle plugin: Portability to 64 bit systems has been improved.
1132 * postgresql plugin: The default configuration has been improved.
1133 * rrdtool plugin: Fix a possible race condition: If the network plugin

1144 faults. Thanks to Peter Holik for his patch.
1146 2009-02-16, Version 4.6.0
1147 * collectd: Added the `filter chain' infrastructure, which allows the
1148 user to use `matches' and `targets' to control value processing.
1149 * collectd: The new `-T' command line argument allows more in-depth
1150 testing of a configuration. Thanks to Doug MacEachern for the patch.

1166 Bruno Prémont for this plugin.
1167 * cpu plugin: Report `interrupt' separately when using
1168 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1169 example for native OpenBSD support, has been added. Thanks to Simon
1170 Kuhnle for the patch.
1171 * csv plugin: Make it possible to write values to STDOUT instead of
1172 files. This is meant for testing purposes mostly. The output written
1173 to STDOUT is compatible with the exec plugin. Thanks to Doug
1174 MacEachern for the patch.
1175 * curl plugin: This new plugin can be used to read web pages and parse
1176 them using the same mechanism that's used in the tail plugin.
1177 * dbi plugin: This new plugin allows you to connect to a variety of
1178 relational databases and use SQL to gather custom statistics from
1179 it. It is similar to the already existing PostgreSQL plugin but uses
1180 libdbi to communicate with the database(s).
1181 * interface plugin: Use the ignorelist framework when selecting /
1182 ignoring interfaces. This allows one to use regular expressions to
1183 select interfaces, too.
1184 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1185 Thanks to Bruno Prémont for this patch.
1186 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

1199 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1200 * perl plugin: Added support for `notification meta data'.
1201 * perl plugin: Added support for the `filter chain' infrastructure by
1202 allowing plugins to register `matches' and `targets'.
1203 * postgresql plugin: The preferred configuration syntax has been
1204 updated to be in line with the syntax used by the new dbi and oracle
1205 plugins. The compatibility code for the old syntax is present.
1206 Support for the new `Result' blocks and the interval parameter has
1208 * processes plugin: Stacksize and virtual memory usage statistics have
1209 been added. Portability fixes.
1210 * rrdcached plugin: This new plugin uses the (still in development)
1211 RRD accelerator daemon, rrdcached. This daemon works very similar to
1212 the original rrdtool plugin of collectd, but adds some more nice
1214 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1217 2009-05-09, Version 4.5.4
1218 * Build system, various plugins: Many build fixes for FreeBSD,

1231 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1233 * rrdtool plugin: Fix a possible race condition: If the network plugin
1234 is initialized and dispatches a value before the rrdtool plugin is
1235 initialized, the daemon may crash.
1236 * memory plugin: Fix a potential problem under Solaris.
1238 2009-02-22, Version 4.5.3

1248 code. Thanks to "thated" for reporting this.
1250 2009-01-02, Version 4.5.2
1251 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1252 file may be in both locations, especially when the database was
1253 installed in a non-standard path. Thanks to Dusty Doris for
1255 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1256 Solaris, in the configure script automatically.
1257 * build system, tcpconns plugin: Check for `kvm_nlist' and
1258 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1259 library with similar functions to the BSD variant, but doesn't
1260 provide these necessary functions.
1261 * collectd.conf(5): Various fixes and clarifications.
1262 * collectd: Remove a GNUism (unnamed unions), thus improving

1267 * filecount plugin: Fix an off-by-one error. This error may cause a
1269 * network plugin: Fix the handling of `type' in the network protocol.
1270 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1271 much larger buffer. This caused the `type' to be transferred much
1272 more often than necessary. In some cases, e. g. the `cpu' and
1273 `cpufreq' plugins being used at the same time, data may be corrupted
1274 in those files. Thanks to Bruno Prémont for debugging and reporting
1276 * processes plugin: Fix a possible segmentation fault when specifying
1277 invalid configuration options.
1278 * unixsock plugin: Make sure the initialization function is run only
1279 once. This resolves a file descriptor leak under systems which run
1280 the initialization more than once, such as Solaris.
1282 2008-10-16, Version 4.5.1
1283 * build system: Change `--enable-<plugin>' to abort with an error if
1284 dependencies are not met. Thanks to Bruno Prémont for the patch.
1285 Also, the poisoning of various string functions has been restricted
1287 * collectd: Fix a memory leak in the global value cache. With every
1288 *missing* value a couple of bytes would be leaked. Another memory
1289 leak in the configuration handling code has been fixed. Thanks to
1290 Niraj Tolia for reporting these issues.
1291 * collectd: Fix an off-by-one error in the ignorelist functionality.
1292 When using regular expressions, the last character would be missing,
1293 possibly matching differently from what one would expect.
1294 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1296 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1297 Linzberger for reporting the bug.
1298 * iptables plugin: Fix an off-by-one error. If a string was just one
1299 character too long, it was truncated instead of reporting an error.
1300 * network plugin: Fix a memory leak in the configuration handling
1301 code. Thanks to Niraj Tolia for reporting this issue.
1302 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1303 * postgresql plugin: Don't reopen connection during reinitialization.
1304 This fixes a bug under Solaris and potentially other platforms.
1305 Missing calls to `PQclear' have been added, too. This fixes memory
1306 leaks. Thanks to ``Admin'' for reporting these bugs.
1307 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1309 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1310 problems with some `libc's. Thanks to Matthias Lay for reporting the
1313 2008-09-04, Version 4.5.0
1314 * collectd: Added the ability to flush certain identifiers.

1322 X desktop using the structure defined in the `Desktop Notification
1324 * notify_email plugin: This new plugin sends out notifications via
1325 email, using the `esmtp' library.
1326 * onewire plugin: The new experimental(!) onewire plugin reads values,
1327 such as temperatures, from sensors connected to the computer via the
1329 * perl plugin: Improved synchronized access to internal data structures
1330 and fixed a possible dead-lock.
1331 * perl plugin: Added the ability to flush certain identifiers and marked
1332 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1334 * perl plugin: Added the ability to configure Perl plugins.

1345 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1346 file may be in both locations, especially when the database was
1347 installed in a non-standard path. Thanks to Dusty Doris for
1349 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1350 Solaris, in the configure script automatically.

1355 * network plugin: Fix the handling of `type' in the network protocol.
1356 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1357 much larger buffer. This caused the `type' to be transferred much
1358 more often than necessary. In some cases, e. g. the `cpu' and

1426 * collectd: Internal code cleanups.
1427 * collectd: Added support for a `Flush' command in the unixsock and
1428 exec plugins. This command can be used to force a plugin (or all) to
1429 flush its values to disk.
1430 * collectd: Thresholds can now be configured to apply to one data
1431 source only, making it possible to configure different thresholds
1432 for each data source.
1433 * apache, nginx plugins: Added the possibility to disable host and/or
1435 * ascent plugin: The new ascent plugin reads and parses the statistics
1436 page of an Ascent server.

1453 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1454 TeamSpeak2 server and collects statistics about the number of users
1455 and number of channels.
1456 * users plugin: Support for the statgrab library has been added.
1457 * vmem plugin: The new vmem plugin collects very detailed statistics
1458 about the virtual memory subsystem of Linux.
1460 2008-08-30, Version 4.3.4
1461 * Build system: Improved detection of and linking with the statgrab
1463 * collectd: Portability fixes, especially to determine endianess more
1465 * Various plugins: Fix format strings.
1466 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1467 again has been applied.
1468 * memcached plugin: Fix a too short timeout and a related file
1470 * memory plugin: A typo in the libstatgrab code has been fixed.
1471 * network plugin: A fix in the initialization function solves problems
1473 * nginx plugin: A thread-unsafe function has been replaced.
1474 * vserver plugin: A thread-unsafe function has been replaced.
1475 * wireless plugin: A work-around for broken wireless drivers has been
1478 2008-04-22, Version 4.3.3
1479 * build system: Improved detection of several libraries, especially if
1480 they are in non-standard paths.
1481 * build system: Portability fixes: Automatically define "_REENTRANT"
1482 if the libc expects it.
1483 * collectd: Error and warning messages have been improved.
1484 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1486 * apache plugin: Allocate new memory when reading a webpage instead of
1487 using a buffer of static size.
1488 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1490 * hddtemp plugin: Error and warning messages have been improved.
1491 * sensors plugin: Fix sensor collection for some chip types.
1493 2008-03-29, Version 4.3.2
1494 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1495 `Persist' threshold options.
1496 * collectd: Fix handling of missing values in the global value cache.
1497 * collectd: Improved error messages when parsing the configuration.
1498 * sensors plugin: Fix temperature collection with libsensors4.
1499 * unixsock plugin: Fix mixed input and output operation on streams.
1500 * wireless plugin: Fix reading noise value.
1502 2008-03-05, Version 4.3.1
1503 * exec plugin: Set supplementary group IDs.
1505 + Use `memcpy' when constructing/parsing a package to avoid
1506 alignment problems on weird architectures, such as Sparc.
1507 + Translate doubles to/from the x86 byte representation to ensure
1508 cross-platform compatibility.
1509 * ping plugin: Correct the handling of the `TTL' setting.
1510 * swap plugin: Reapply a patch for Solaris.
1511 * tcpconns plugin: Portability improvements.
1513 2008-02-18, Version 4.3.0
1514 * collectd: Notifications have been added to the daemon. Notifications
1515 are status messages that may be associated with a data instance.
1516 * collectd: Threshold checking has been added to the daemon. This
1517 means that you can configure threshold values for each data
1518 instance. If this threshold is exceeded a notification will be
1520 * collectd: The new `FQDNLookup' option tells the daemon to use the
1521 full qualified domain name as the hostname, not just the host part
1522 es returned by `gethostname(2)'.
1523 * collectd: Support for more than one `TypesDB' file has been added.
1524 This is useful when one such file is included in a package but one
1525 wants to add custom type definitions.
1526 * collectd: The `Include' config option has been expanded to handle
1527 entire directories and shell wildcards.
1528 * collectdmon: The new `collectdmon' binary detects when collectd
1529 terminates and automatically restarts it again.
1530 * csv plugin: The CSV plugin is now able to store counter values as a
1531 rate, using the `StoreRates' configuration option.
1532 * exec plugin: Handling of notifications has been added and the
1533 ability to pass arguments to the executed programs has been added.
1534 * hddtemp plugin: The new `TranslateDevicename' option lets you
1535 disable the translation from device names to major-minor-numbers.
1536 * logfile plugin: Handling of notifications has been added.
1537 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1538 domain name lookups in this plugin.
1539 * perl plugin: Many internal changes added support for handling multiple
1540 threads making the plugin reasonably usable inside collectd. The API has
1541 been extended to support notifications and export global variables to
1542 Perl plugins; callbacks now have to be identified by name rather than a
1543 pointer to a subroutine. The plugin is no longer experimental.
1544 * uuid plugin: The new UUID plugin sets the hostname to an unique
1545 identifier for this host. This is meant for setups where each client
1546 may migrate to another physical host, possibly going through one or
1547 more name changes in the process. Thanks to Richard Jones from
1548 Red Hat's Emerging Technology group for this plugin.
1549 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1550 CPU, disk and network statistics about guest systems on the same
1551 physical server. Thanks to Richard Jones from Red Hat's Emerging
1552 Technology group for this plugin.
1554 2008-04-22, Version 4.2.7
1555 * build system: Improved detection of several libraries, especially if
1556 they are in non-standard paths.
1557 * build system: Portability fixes: Automatically define "_REENTRANT"
1558 if the libc expects it.
1559 * collectd: Error and warning messages have been improved.
1560 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1562 * apache plugin: Allocate new memory when reading a webpage instead of
1563 using a buffer of static size.
1564 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1566 * hddtemp plugin: Error and warning messages have been improved.
1567 * sensors plugin: Fix sensor collection for some chip types.
1569 2008-03-29, Version 4.2.6
1570 * collectd: Improved error messages when parsing the configuration.
1571 * sensors plugin: Fix temperature collection with libsensors4.
1572 * unixsock plugin: Fix mixed input and output operation on streams.
1573 * wireless plugin: Fix reading noise value.
1575 2008-03-04, Version 4.2.5
1576 * apache plugin: Improved initialization and error messages.
1577 * exec plugin: Set supplementary group IDs.
1579 + Create separate threads for reading from the socket and parsing
1580 and dispatching incoming packets. Versions prior to this may have
1581 problems in high-load situations, where the socket receive buffers
1582 overflows, resulting in gaps in the data.
1583 + Use `memcpy' when constructing/parsing a package to avoid
1584 alignment problems on weird architectures, such as Sparc.
1585 + Translate doubles to/from the x86 byte representation to ensure
1586 cross-platform compatibility.
1587 * ping plugin: Correct the handling of the `TTL' setting.
1588 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1589 * swap plugin: Reapply a patch for Solaris.
1590 * tcpconns plugin: Portability improvements.
1592 2008-01-21, Version 4.2.4
1593 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1594 the permission on the socket as documented in the manpage. Thanks to
1595 Evgeny Chukreev for fixing this issue.
1596 * collectd: The documentation has been improved.
1598 2007-12-28, Version 4.2.3
1599 * sensors plugin: Updated the plugin to build and work with version 3
1600 of the libsensors library.
1602 2007-12-15, Version 4.2.2
1603 * nginx plugin: Incorrect comparison of strings lead to a segfault
1604 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1606 * logfile plugin: The config option `Timestamp' was handled
1607 incorrectly and basically always active. Thanks to Luke Heberling
1610 2007-11-08, Version 4.2.1
1611 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1612 enabled on the host.
1613 * snmp plugin: Fix a memory leak.
1615 2007-10-27, Version 4.2.0
1616 * collectd: The new config option `Include' lets you include other
1617 configfiles and thus split up your config into smaller parts. This
1618 may be especially interesting for the snmp plugin to keep the data
1619 definitions separate from the host definitions.
1620 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1621 (number of connections, octets and packets for each service and
1622 destination). Thanks to Sebastian Harl for this plugin.
1623 * memcached plugin: The new `memcached' plugin connects to a memcached
1624 daemon process and collects statistics of this distributed caching
1625 system. Thanks to Antony Dovgal for contributing this plugin.
1626 * nginx plugin: The new `nginx' plugin reads the status page of an
1627 nginx daemon and saves the handled connections and requests.
1628 * perl plugin: Many changes, including the added `EnableDebugger'
1629 config option which lets you debug your Perl plugins more easily.
1630 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1631 be more thread-safe otherwise by locking calls to the library.
1632 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1633 correct the values returned by SNMP-agents. If a <data> block is
1634 defined as `table' the instance is now optional. The sequence number
1635 is used as the type-instance in this case. The new `InstancePrefix'
1636 option allows to add arbitrary prefixes to the type-instance.
1637 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1638 certain TCP connections and what state they're in. This can be used
1639 to see how many connections your FTP server has to handle or how
1640 many outgoing connections your mailserver has open.
1642 2008-01-11, Version 4.1.6
1643 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1644 the permission on the socket as documented in the manpage. Thanks to

1652 of the libsensors library.
1654 2007-11-08, Version 4.1.4
1655 * Build system: Improve detection of the rrd library, especially if
1656 it's in a non-standard location.
1657 * Build system: A bug when parsing the argument for
1658 `--with-libnetsnmp' has been fixed.
1659 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1660 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1661 a deadlock or delay when shutting down the daemon.
1662 * snmp plugin: Fix a memory leak.
1664 2007-10-24, Version 4.1.3
1665 * collectd: A build issue under Solaris has been resolved by renaming
1667 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1668 be more thread-safe otherwise by locking calls to the library.
1670 2007-09-28, Version 4.1.2
1671 * apcups plugin: Fix reporting of the `load percent' data.
1672 * wireless plugin: Correct the handling of cards returning signal and
1673 noise quality as percentage.
1674 * perl plugin: Fix a possible buffer overflow in get_module_name().
1675 * build system: Further improve the detection of libraries.
1676 * netlink plugin: Build issues under some older versions of the Linux
1677 includes (i. e. Debian Sarge) have been fixed.
1678 * snmp plugin: Fix a potential segfault when a host times out. Add
1679 support for the `timeticks' type.
1681 2007-09-12, Version 4.1.1
1682 * Build system: The detection of `libnetlink' has been improved.
1683 * collectd: The documentation has been fixed in numerous places.
1684 * exec plugin: Setting the group under which to run a program has been
1686 * collectd: The `sstrerror' function was improved to work correctly
1687 with the broken GNU version of `strerror_r'.
1688 * collectd: Write an error message to STDERR when loading of a plugin
1690 * apcups plugin: Fix the `types' used to submit the values: They still
1691 has an `apcups_' prefix which doesn't work anymore.
1692 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1693 whatever the client thinks is `now'..
1695 2007-09-01, Version 4.1.0
1696 * Build system: The build system has been changed to automatically
1697 disable all plugins, which are missing dependencies. The dependency
1698 checking has been removed from the plugins themselves to remove
1700 * Flexible interval: The interval of collected data is now sent along
1701 with the data itself over the network, so that the interval-settings
1702 of server and clients no longer needs to match.
1703 * netlink plugin: The new `netlink' plugin connects to the Linux
1704 kernel using a netlink socket and uses it to query information about
1705 interfaces, qdiscs and classes.
1706 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1707 to not block data collection.
1708 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1709 network devices, such as switches, routers, thermometers, rack
1710 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1712 * unixsock plugin: Added the `LISTVAL' command.
1713 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1714 of music played with xmms.
1716 2007-09-28, Version 4.0.9
1717 * apcups plugin: Fix reporting of the `load percent' data.
1718 * wireless plugin: Correct the handling of cards returning signal and
1719 noise quality as percentage.
1720 * perl plugin: Fix a possible buffer overflow in get_module_name().
1722 2007-09-12, Version 4.0.8
1723 * collectd: The `sstrerror' function was improved to work correctly
1724 with the broken GNU version of `strerror_r'.
1725 * collectd: Write an error message to STDERR when loading of a plugin
1727 * apcups plugin: Fix the `types' used to submit the values: They still
1728 has an `apcups_' prefix which doesn't work anymore.
1729 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1730 whatever the client thinks is `now'..
1732 2007-08-26, Version 4.0.7
1733 * documentation: Some typos have been fixed and some information has
1735 * build system: Many fixes for detecting libraries in unusual places,
1736 such as on RedHat systems. The affected libraries are `libcurl',
1737 `libmysql', and `libupsclient'.
1738 * network plugin: Allow the `Port' option to be specified as a number
1739 (i. e. without quotes).
1740 * nut plugin: A fix allows linking the nut plugin against
1741 libupsclient, version >= 2.2.0.
1742 * processes plugin: Fix a potential segmentation fault.
1744 2007-07-30, Version 4.0.6
1745 * sensors plugin: Fix the ignorelist functionality: Only the `type
1746 instance' was used to match against the list, but the documentation
1747 told otherwise. This release fixes the code, so it complies with the
1749 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1750 configuration messages will end up in the logging facility.
1751 * conrtib/fedora: The contributed specfile for Fedora has been
1754 2007-07-05, Version 4.0.5
1755 * Portability: More fixes for OpenBSD have been included.
1757 2007-06-24, Version 4.0.4
1758 * cpu plugin: Fixed the Solaris code.

1760 * interface plugin: Fixed the Solaris code.
1761 * load plugin: Fixed the alternative `/proc' Linux code.
1762 * memory plugin: Fixed the Solaris code.
1763 * oconfig: Don't require `-lfl' anymore.
1765 2007-06-19, Version 4.0.3
1766 * cpu plugin: Fix the Darwin / Mac OS X code.
1767 * ping plugin: Use the return value of `getpid', not its address.
1768 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1769 initialized correctly.
1770 * configure: Added `--with-nan-emulation' to aid cross compilation.
1772 2007-06-12, Version 4.0.2
1773 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1774 they're given in numerically form.
1776 2007-06-07, Version 4.0.1
1777 * iptables plugin: A bug in the configuration routine has been fixed.
1778 Setting a comment in the configfile will no longer cause a
1781 2007-06-03, Version 4.0.0
1782 * collectd: The plugin-infrastructure has been changed to allow for
1783 more types of plugins, namely `write' and `log' plugins.
1784 * collectd: The read-function has been changed to read many plugins in
1785 parallel, using threads. Thus, plugins generally need to use
1786 thread-safe functions from now on.
1787 * collectd: The '-t' command line options allows to perform syntax tests
1788 of the configuration file and exit immediately.
1789 * csv plugin: The new `csv' plugin handles output to `comma separated
1791 * rrdtool plugin: The new `rrdtool' plugin handles output to
1792 RRD-files. Data can be cached to combine multiple updates into one
1793 write to increase IO-performance.
1794 * network plugin: The new `network' plugin handles IO via the network.
1795 It implements a different, much more extensible protocol which can
1796 combine many values in one packet, decreasing the number of UDP-
1797 packets being sent. It can read from and send to the network and
1798 with the appropriate configuration even forward packets to other
1800 * unixsock plugin: The new `unixsock' plugin provides an interface to
1801 communicate with the daemon while it is running. Right now the
1802 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1804 * perl plugin: The new `perl' plugin allows you to write extensions
1805 for collectd in the scripting-language Perl.
1806 * logfile plugin: The new `logfile' plugin writes logmessages to files
1807 or STDOUT or STDERR.
1808 * syslog plugin: The new `syslog' plugin sends logmessages to the
1809 system's syslog daemon.
1810 * entropy plugin: The new `entropy' plugin collects the amount of
1811 entropy currently being available to the system.
1812 * exec plugin: The new `exec' plugin forks child processes and reads
1813 back values provided by the forked processes.
1814 * iptables plugin: The new `iptables' plugin reads counters from
1815 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1817 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1818 to Peter Holik for contributing this plugin.
1819 * nut plugin: The new `nut' plugin connects the upsd of the `network
1820 ups tools' and reads information about the connected UPS.
1821 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1822 connections) field was added by Florent Monbillard.
1823 * collectd-nagios: The new `collectd-nagios' binary queries values
1824 from collectd, parses them and exits according to Nagios-standards.
1825 * manpages: The manpages have been improved a lot.
1827 2007-09-28, Version 3.11.7
1828 * wireless plugin: Correct the handling of cards returning signal and
1829 noise quality as percentage.
1831 2007-08-31, Version 3.11.6
1832 * processes plugin: Fix a potential segmentation fault.
1834 2007-05-29, Version 3.11.5
1835 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1836 * ntpd plugin: Fix a potential buffer overflow.
1837 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1838 were accounted as `zombies'.
1840 2007-04-10, Version 3.11.4
1841 * dns plugin: Change the order of includes to make the plugin compile
1844 2007-03-30, Version 3.11.3
1845 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1846 of the unused `COLLECT_KSTAT'.
1848 2007-02-11, Version 3.11.2
1849 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1850 NULL-pointer may have been passed to `printf' which causes a
1851 segfault with some libcs.
1853 2007-02-10, Version 3.11.1
1854 * df plugin: Some wrong defines have been fixed so the plugin works
1855 under Solaris again.
1856 * dns plugin: The usage of a struct has been fixed to work with
1858 * processes plugin: Some missing defines have been added so the plugin
1859 compiles cleanly under FreeBSD and presumably other UNIXes.
1861 2006-12-22, Version 3.11.0
1862 * collectd: The new command line option `-P' makes it easier for
1863 distributors to change the location of PID-files.
1864 * collectd: The daemon shuts down faster now which makes it easier to
1865 write init.d-scripts for it.
1866 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1867 caused problems every now and then.
1868 * df plugin: New config options allow to ignore certain mountpoints,
1869 filesystem types or devices.
1870 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1871 and interprets it. It collects traffic as well as qtype, opcode and
1873 * email plugin: Sebastian Harl has contributed this plugin which
1874 counts received mails in categories (e. g. ham, spam, virus), spam
1875 score (as given by SpamAssassin) and check types.
1876 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1877 uses `mbmon' to gather information from sensors on the motherboard.
1878 * processes plugin: Collect detailed statistics for configured
1879 processes, that's process and thread count, CPU usage, resident
1880 segment size and pagefaults.
1881 * multimeter plugin: Peter Holik contributed a new plugin which
1882 queries multimeters.
1883 * sensors plugin: Lubos Stanek has put much effort into improving this
1884 plugin, including `extended naming', collection of voltage values
1885 and the possibility to ignore certain values.
1887 2006-12-21, Version 3.10.4
1888 * Max Kellermann has identified a bug in the server routine: When
1889 opening a socket fails the daemon will (re)try opening the socket in
1890 an endless loop, ultimately leading to a `EMFILE' error.
1892 2006-11-04, Version 3.10.3
1893 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1894 ntpd's reply was sent in more than one packet, the buffer size was
1895 calculated incorrectly, resulting in the reading of uninitialized or
1898 2006-11-01, Version 3.10.2
1899 * The sample config file has been improved.
1900 * Errors in the manpages have been corrected.
1901 * The ping-plugin now adds hosts during initialization, not during
1902 startup. This speeds up startup when no network connectivity is
1903 available. Also, the hosts are being added later when the network is
1905 * Improved BSD-support for the df-plugin.
1906 * Fixed syntax errors in the swap-plugin for Mac OS X.
1907 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1909 * Don't disable the mysql-plugin if connecting to the database fails
1910 during initialization. Instead, try again in increasing intervals.
1912 2006-07-19, Version 3.10.1
1913 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1914 the apcups cannot be reached, unconnected sockets will pile up and
1915 eventually lead to `Too many open files' errors.
1917 2006-07-09, Version 3.10.0
1918 * The `disk' plugin has been ported to Darwin.
1919 * The `battery' plugin should work on many Apple computers now.
1920 * The `traffic' plugin can now ignore certain interfaces. Also,
1921 statistics for sent/received packets and errors have been added.
1922 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1923 to Anthony Gialluca for contributing this plugin and providing me
1924 with a test environment :)
1925 * A plugin for monitoring an NTP instance and the local clock drift
1928 2006-06-25, Version 3.9.4
1929 * The Solaris code in the `swap' plugin has been changed to reflect
1930 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1932 * The debugging system has been fixed to work with the Sun libc.
1933 * When built without librrd the variable `operating_mode' could be
1934 uninitialized. Thanks to David Elliot for reporting the bug.
1936 2006-06-01, Version 3.9.3
1937 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1938 operating systems also profit from the changes, but I wasn't able to
1940 * Changed the build system to find the netinet-includes under FreeBSD
1941 and therefore successfully build the `liboping' library there.
1943 2006-05-09, Version 3.9.2
1944 * Applied a patch to the `liboping' library. Due to a bug in the
1945 sequence checking the `ping' plugin stopped working after
1946 approximately 7.6 days.
1948 2006-05-09, Version 3.8.5
1949 * Applied a patch to the `liboping' library. Due to a bug in the
1950 sequence checking the `ping' plugin stopped working after
1951 approximately 7.6 days.
1953 2006-04-21, Version 3.9.1
1954 * Build issues with Solaris and possible other architectures have been
1956 * Problems when building the `apache'-plugin without `libcurl' have
1958 * A bug in the `ping' plugin has been fixed. Sorry folks.
1960 2006-04-02, Version 3.9.0
1961 * A plugin to monitor the Apache webserver has been added.
1962 <http://httpd.apache.org/>
1963 * A plugin to collect statistics about virtual servers using VServer.
1964 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1966 * A plugin for wireless LAN cards has been added. It monitors signal
1967 strength, link quality and noise ratio..
1968 * A plugin for Apple hardware sensors has been added.
1969 * An option to compile collectd with different `step' and `heartbeat'
1970 settings has been added. The size of RRAs is no longer static but
1971 calculated based on the settings for `step' and `width'.
1972 * The `ping' plugin can now be configured to use a certain TTL.
1973 * A plugin to monitor the hardware sensors of Apple computers has been
1975 * The plugins `cpu', `memory', `processes' and `traffic' have been
1976 ported to Mach/Darwin (Mac OS X).
1977 * The `log mode' has been contributed by Christophe Kalt. It writes
1978 the data into text files rather than RRD files.
1980 2006-04-09, Version 3.8.4
1981 * Applied patch by Vincent Stehlé which improves the disk-name
1982 resolution in the `hddtemp' plugin for Linux systems.
1984 2006-04-02, Version 3.8.3
1985 * Applied a patch by James Byers: The MySQL plugin was not working
1986 with MySQL 5.0.2 or later.
1988 2006-03-14, Version 3.8.2
1989 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1990 the GNU libc, because it points to `/etc/fstab' rather than
1993 2006-03-13, Version 3.8.1
1994 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1995 * Fixes in the debian `postinst' and `init.d' scripts.
1997 2006-03-09, Version 3.8.0
1998 * The `ping' plugin no longer uses `libping' but a self written
1999 library named `liboping'. With this library it's possible to ping
2000 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2002 2006-02-18, Version 3.7.2
2003 * A simple bug in the `battery' plugin has been fixed. It should now
2004 work with ACPI based batteries as well. Thanks to Sebastian for
2006 * Fixing a bug that prevented collectd to be built without librrd.
2007 Thanks to Werner Heuser for reporting it.
2009 2006-02-04, Version 3.7.1
2010 * The new network code has been improved to build with older versions
2012 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2013 to Tommie Gannert for this patch.
2015 2006-01-30, Version 3.7.0
2016 * The `battery' plugin has been added. It collects information about
2018 * The MySQL plugin has been improved: It now writes two more RRD
2019 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2020 * The `cpufreq' plugin now reads another file since the file it did
2021 read so far causes much overhead in the kernel. Also, you need root
2022 to read the old file, but not to read the new one.
2023 * The `hddtemp' plugin can now be configured to connect to another
2024 address and/or port than localhost.
2025 * The `df' plugin now prefers `statvfs' over `statfs'.
2026 * The network code has been rewritten. collectd now supports unicast
2027 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2028 be set in the configfile.
2030 2006-01-24, Version 3.6.2
2031 * Due to a bug in the configfile handling collectd wouldn't start in
2032 client mode. This released fixes this.
2034 2006-01-20, Version 3.6.1
2035 * Due to a bug in `configure.in' all modules and the binary were
2036 linked against `libmysqlclient'. This issue is solved by this
2039 2006-01-17, Version 3.6.0
2040 * A config file has been added. This allows for loading only specific
2042 * A `df' plugin has been added.
2043 * A `mysql' plugin has been added.
2044 * The `ping' plugin doesn't entirely give up hope when a socket error
2045 occurred, but will back of and increase the intervals between tries.
2047 2006-01-21, Version 3.5.2
2048 * Fixed yet another bug in the signal handling.. Stupid typo..
2049 * Improved the ping plugin to not give up on socket errors (backport
2052 2005-12-18, Version 3.5.1
2053 * The PID-file is now deleted correctly when shutting down the daemon.
2054 * SIGINT and SIGTERM are now handled correctly.
2056 2005-12-16, Version 3.5.0 (Revision 326)
2057 * A bug in the `load' module under Solaris has been fixed.
2058 * The `users' module has been contributed by Sebastian Harl. It counts
2059 currently logged in users.
2060 * The CPU module now works under FreeBSD without the use of
2061 `libstatgrab', however SMP support is missing.
2062 * The default directories for the RRD files and the PID file now
2063 depend on the compile time setting of `localstatedir'.
2065 2005-11-15, Version 3.4.0 (Revision 236)
2066 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2067 from gentoo's bugzilla for writing the patch.
2068 * The build dependency for librrd has been removed. Binaries built
2069 without librrd are client-only and will multicast their value as
2070 with the `-c' argument.
2071 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2072 * The newly introduced `-f' switch prevents daemon initialization
2073 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2074 Barcellos for this patch.
2076 2005-11-04, Version 3.3.0 (Revision 216)
2077 * New modules have been added:
2078 - `serial', for monitoring traffic on the serial interfaces
2079 - `nfs', for graphing NFS procedure calls
2080 - `tape', traffic from/to tape devices
2081 * The memory.rrd now accepts more than 4Gig of memory.
2083 2005-10-26, Version 3.2.0 (Revision 200)
2084 * Support for graphing the processes has been added (thanks to Lyonel
2086 * If reading from hddtemp fails collectd will increase the time
2087 between polls up to one day.
2088 * The init.d files have been improved.
2089 * Problems with the spec file have been fixed.
2091 2005-10-16, Version 3.1.0 (Revision 194)
2092 * Added the `setsid' syscall to the startup code.
2093 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2095 2005-09-30, Version 3.0.0 (Revision 184)
2096 * The ability to send/receive data to/from the network (think
2097 multicast) has been added.
2098 * Modules have been split up into shared libraries can be loaded at
2099 runtime. The biggest advantage is that the core program doesn't need
2100 to be linked against an external library.
2101 * A patch by George Kargiotakis has been applied: It fixes the sensors
2102 behaviour then more than one sensor is being queried.
2104 2005-09-16, Version 2.1.0 (Revision 172)
2105 * A module for swap statistics has been added.
2107 2005-09-09, Version 2.0.0 (Revision 135)
2108 * Filenames can no longer be configured at program startup. The only
2109 options as of this version are the directory and ping hosts.
2110 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2111 Soft-IRQ statistics are added to `System'.
2112 * Diskstats now collect read and write bytes, not sectors.
2113 * Ping statistics can now be collected for more than one host. There
2114 is no default any more: If no host is given no host will be pinged.
2115 * A self-written patch for libping has been applied so it builds
2118 2005-09-01, Version 1.8.1 (Revision 123)
2119 * Much improved configure-script: libraries and features may now be
2121 * More detailed warnings/error messages when RRD update fails.
2123 2005-08-29, Version 1.8.0:
2124 * Support for collecting disk statistics under Solaris.
2126 2005-08-25, Version 1.7.0:
2127 * Support for libstatgrab[1] for load, memory usage and network
2128 traffic. CPU- and disk-usage are not (yet) supported, since
2129 libstatgrab returns insufficient information. I will contact the
2131 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2132 aren't necessarily counted linear which is now handled correctly.
2133 [1]: http://www.i-scream.org/libstatgrab/
2135 2005-08-21, Version 1.6.0:
2136 * Basic support for Solaris: System load and cpu-usage can be
2137 collected under Solaris, too. Other stats will follow later.
2138 * Many fixes in the autoconf-script
2139 * Collection/Museum scripts have been added under contrib/museum
2140 * collectd may now be started in unprivileged mode, though ping
2141 statistics will not work.
2143 2005-07-17, Version 1.5.1:
2144 * Diskstats-RRDs now use major/minor for naming. Some systems have
2145 weird strings as disk-names..
2147 2005-07-17, Version 1.5:
2148 * A new module, diskstats, has been added. It collects information
2149 about the disks and partitions.
2151 2005-07-11, Version 1.4.2:
2152 * The meminfo module has been changed to work with more platforms
2153 and/or kernel versions.
2155 2005-07-10, Version 1.4.1: Correct traffic stats
2156 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2157 forgot to correct when I changed that module.
2159 2005-07-09, Version 1.4: More traffic stats
2160 * Traffic is now collected for all interfaces that can be found
2161 * Temperature-statistics are read from lm-sensors if available
2163 2005-07-08, Version 1.3: CPU stats
2164 * Collecting CPU statistics now
2166 2005-07-12, Version 1.2: Using syslog
2167 * collectd is now using the syslog facility to report errors, warnings
2169 * The default directory is now /var/db/collectd
2171 2005-07-10, Version 1.1: Minor changes
2172 * Nothing really useful to say ;)
2174 2005-07-09, Version 1.0: Initial Version
2175 * The following modules are provided:
