990 fixed. Thanks to Ben Knight for his patch.
992 2009-10-03, Version 4.7.4
993 * Build system: Issues when building the iptables plugin have been
995 * exec plugin: Clear the signal block mask before calling exec(2).
996 * perl plugin: Declare the “environ” variable. This solves build
997 issues on some platforms.
998 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
999 Andrés J. Díaz for the patch.
1000 * unixsock plugin: Fix a (well hidden) race condition related to file
1001 descriptor handling.
1003 2009-09-13, Version 4.7.3
1004 * collectd: Fix a possible but very rare invalid “free” in the caching
1005 code. Thanks to Sebastian Harl for the patch.
1006 * collectd: Remove old values when a cache entry is marked as missing.
1007 This way the “GETVAL” command of the UnixSock plugin doesn't return
1008 old, no longer valid values when this happens. Thanks to Andrés J.
1010 * collectd: The “plugin_unregister_read” function has been fixed.
1011 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1012 to follow redirects. Thanks to Joey Hess for reporting this bug.

1018 updated to the plugin only includes the shipped header files when it
1019 is linked with the shipped library, too.
1020 * java plugin: Delay creating the JVM until after the daemon has
1021 forked. The JVM internally creates threads that are lost when
1022 forking. This means that Java-based plugins are now configured
1023 during the init-phase, i. e. later than other plugins.
1024 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
1025 to Alan Pevec for the patch.
1026 * network plugin: Fix the handling of the “CacheFlush” option: The

1048 details have been added to the configuration summary. Support for
1049 libtool 2.2 has been added.
1050 * collectd: Two bugs with the threshold checking have been fixed. The
1051 first one prevented thresholds to be checked at all, the second one
1052 caused wrong behavior with the persistency option. Thanks to Andrés
1053 J. Díaz for fixing these problems.
1054 * collectd: Handling of the `Include' configuration option has been
1056 * rrdtool plugin: Make sure initialization is run only once. This
1057 resolves problems under Solaris and potentially other systems.
1058 Thanks to Amit Gupta for reporting this bug.
1059 * java plugin: Make it possible to use dots ('.') instead of slashes
1060 ('/') as the class separator. Thanks to Randy Rizun for pointing

1076 multicast traffic from Ganglia's gmond daemon.
1077 * java plugin: The new java plugin exports the collectd API to Java,
1078 making it possible to write extensions to collectd in Java.
1079 * memcachec plugin: The new memcachec plugin queries data from a
1080 memcached daemon and parses it similar to the cURL plugin. Thanks to
1081 Doug MacEachern for the initial code.
1082 * memcached plugin: Support for connections over UNIX domain sockets
1083 has been added. Thanks to Franck Lombardi for the patch.

1098 structured files, such as many files beneath /proc.
1099 * ted plugin: The new TED plugin reads power consumption measurements
1100 from “The Energy Detective” (TED). Thanks to Eric Reed for this
1102 * onewire plugin: The new `Interval' option allows collecting
1103 information from OneWire sensors at arbitrary intervals.
1104 * ping plugin: Support for collecting the drop rate and standard
1105 deviation of round-trip times has been added.
1106 * uptime plugin: The new uptime plugin can collect the server's
1107 uptime. Thanks to Marco Chiappero for the patch.
1109 2009-09-10, Version 4.6.5
1110 * collectd: Remove old values when a cache entry is marked as missing.
1111 This way the “GETVAL” command of the UnixSock plugin doesn't return

1139 * Build system, various plugins: Many build fixes for FreeBSD,
1140 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1141 for many fixes and providing a build system for many platforms,
1142 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1143 providing an OpenBSD system.
1144 * collectd: Two bugs with the threshold checking have been fixed. The
1145 first one prevented thresholds to be checked at all, the second one
1146 caused wrong behavior with the persistency option. Thanks to Andrés
1147 J. Díaz for fixing these problems.

1164 * filter subsystem: Allow `Chains' without default targets.
1165 * liboping: A patch to comply with strict aliasing rules has been
1167 * timediff match: Fix a typo: The match was registered with a wrong
1168 name which prevented this match to be used as documented. Thanks to
1169 Bruno Prémont for finding this problem.
1170 * bind plugin: Fix collection of the cached RR sets. The number of RR
1171 sets currently in the cache was collected as a counter value, which
1172 is nonsense. Thanks to Bruno Prémont for implementing this.
1173 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1174 primarily BSDs, don't take it well and crash.
1175 * oracle plugin: Portability to 64 bit systems has been improved.
1176 * postgresql plugin: The default configuration has been improved.
1177 * rrdtool plugin: Fix a possible race condition: If the network plugin

1188 faults. Thanks to Peter Holik for his patch.
1190 2009-02-16, Version 4.6.0
1191 * collectd: Added the `filter chain' infrastructure, which allows the
1192 user to use `matches' and `targets' to control value processing.
1193 * collectd: The new `-T' command line argument allows more in-depth
1194 testing of a configuration. Thanks to Doug MacEachern for the patch.

1210 Bruno Prémont for this plugin.
1211 * cpu plugin: Report `interrupt' separately when using
1212 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1213 example for native OpenBSD support, has been added. Thanks to Simon
1214 Kuhnle for the patch.
1215 * csv plugin: Make it possible to write values to STDOUT instead of
1216 files. This is meant for testing purposes mostly. The output written
1217 to STDOUT is compatible with the exec plugin. Thanks to Doug
1218 MacEachern for the patch.
1219 * curl plugin: This new plugin can be used to read web pages and parse
1220 them using the same mechanism that's used in the tail plugin.
1221 * dbi plugin: This new plugin allows you to connect to a variety of
1222 relational databases and use SQL to gather custom statistics from
1223 it. It is similar to the already existing PostgreSQL plugin but uses
1224 libdbi to communicate with the database(s).
1225 * interface plugin: Use the ignorelist framework when selecting /
1226 ignoring interfaces. This allows one to use regular expressions to
1227 select interfaces, too.
1228 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1229 Thanks to Bruno Prémont for this patch.
1230 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

1243 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1244 * perl plugin: Added support for `notification meta data'.
1245 * perl plugin: Added support for the `filter chain' infrastructure by
1246 allowing plugins to register `matches' and `targets'.
1247 * postgresql plugin: The preferred configuration syntax has been
1248 updated to be in line with the syntax used by the new dbi and oracle
1249 plugins. The compatibility code for the old syntax is present.
1250 Support for the new `Result' blocks and the interval parameter has
1252 * processes plugin: Stacksize and virtual memory usage statistics have
1253 been added. Portability fixes.
1254 * rrdcached plugin: This new plugin uses the (still in development)
1255 RRD accelerator daemon, rrdcached. This daemon works very similar to
1256 the original rrdtool plugin of collectd, but adds some more nice

1274 Tomasz Pala for the patch.
1275 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1277 * rrdtool plugin: Fix a possible race condition: If the network plugin
1278 is initialized and dispatches a value before the rrdtool plugin is
1279 initialized, the daemon may crash.
1280 * memory plugin: Fix a potential problem under Solaris.
1282 2009-02-22, Version 4.5.3

1292 code. Thanks to "thated" for reporting this.
1294 2009-01-02, Version 4.5.2
1295 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1296 file may be in both locations, especially when the database was
1297 installed in a non-standard path. Thanks to Dusty Doris for
1299 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1300 Solaris, in the configure script automatically.
1301 * build system, tcpconns plugin: Check for `kvm_nlist' and
1302 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1303 library with similar functions to the BSD variant, but doesn't
1304 provide these necessary functions.
1305 * collectd.conf(5): Various fixes and clarifications.
1306 * collectd: Remove a GNUism (unnamed unions), thus improving
1308 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1309 This solves portability problems, especially for Solaris.

1311 * filecount plugin: Fix an off-by-one error. This error may cause a
1313 * network plugin: Fix the handling of `type' in the network protocol.
1314 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1315 much larger buffer. This caused the `type' to be transferred much
1316 more often than necessary. In some cases, e. g. the `cpu' and
1317 `cpufreq' plugins being used at the same time, data may be corrupted
1318 in those files. Thanks to Bruno Prémont for debugging and reporting
1320 * processes plugin: Fix a possible segmentation fault when specifying
1321 invalid configuration options.
1322 * unixsock plugin: Make sure the initialization function is run only
1323 once. This resolves a file descriptor leak under systems which run
1324 the initialization more than once, such as Solaris.
1326 2008-10-16, Version 4.5.1
1327 * build system: Change `--enable-<plugin>' to abort with an error if
1328 dependencies are not met. Thanks to Bruno Prémont for the patch.
1329 Also, the poisoning of various string functions has been restricted
1331 * collectd: Fix a memory leak in the global value cache. With every
1332 *missing* value a couple of bytes would be leaked. Another memory
1333 leak in the configuration handling code has been fixed. Thanks to
1334 Niraj Tolia for reporting these issues.
1335 * collectd: Fix an off-by-one error in the ignorelist functionality.
1336 When using regular expressions, the last character would be missing,
1337 possibly matching differently from what one would expect.
1338 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1340 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1341 Linzberger for reporting the bug.
1342 * iptables plugin: Fix an off-by-one error. If a string was just one
1343 character too long, it was truncated instead of reporting an error.
1344 * network plugin: Fix a memory leak in the configuration handling
1345 code. Thanks to Niraj Tolia for reporting this issue.
1346 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1347 * postgresql plugin: Don't reopen connection during reinitialization.
1348 This fixes a bug under Solaris and potentially other platforms.
1349 Missing calls to `PQclear' have been added, too. This fixes memory
1350 leaks. Thanks to ``Admin'' for reporting these bugs.
1351 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1353 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1354 problems with some `libc's. Thanks to Matthias Lay for reporting the
1357 2008-09-04, Version 4.5.0
1358 * collectd: Added the ability to flush certain identifiers.

1362 files in a directory and its subdirectories.
1363 * ipmi plugin: Sensor names have been changed to ensure unique names.
1364 Notifications upon added and removed sensors can now be generated.
1365 * notify_desktop plugin: This new plugin sends notifications to the
1366 X desktop using the structure defined in the `Desktop Notification
1368 * notify_email plugin: This new plugin sends out notifications via
1369 email, using the `esmtp' library.
1370 * onewire plugin: The new experimental(!) onewire plugin reads values,
1371 such as temperatures, from sensors connected to the computer via the
1373 * perl plugin: Improved synchronized access to internal data structures
1374 and fixed a possible dead-lock.
1375 * perl plugin: Added the ability to flush certain identifiers and marked
1376 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1378 * perl plugin: Added the ability to configure Perl plugins.
1379 * postgresql plugin: The new postgresql plugin collects statistics
1380 about or from a PostgreSQL database.

1386 using Linux ACPI thermal zone data.
1388 2009-01-02, Version 4.4.5
1389 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1390 file may be in both locations, especially when the database was
1391 installed in a non-standard path. Thanks to Dusty Doris for
1393 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1394 Solaris, in the configure script automatically.
1395 * collectd.conf(5): Various fixes and clarifications.

1397 portability problems, especially for Solaris.
1398 * dns plugin: Fix a portability problem with NetBSD.
1399 * network plugin: Fix the handling of `type' in the network protocol.
1400 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1401 much larger buffer. This caused the `type' to be transferred much
1402 more often than necessary. In some cases, e. g. the `cpu' and

1449 cleared a buffer regardless of its contents. This could lead to lost
1450 values under Solaris.
1451 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1452 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1454 * wireless plugin: Work around incorrect noise and power values
1455 returned by some broken drivers.
1457 2008-06-03, Version 4.4.1
1458 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1459 to kyrone for reporting this.
1460 * collectd: Fixed min/max output in notifications generated by
1462 * collectd-nagios: Fix the protocol used to communicate with the
1464 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1465 initialization has errors. An issue with Perl 5.10 has been fixed.
1466 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1467 René Rebe and Siegmund Gorr for reporting this.
1469 2008-05-06, Version 4.4.0
1470 * collectd: Internal code cleanups.
1471 * collectd: Added support for a `Flush' command in the unixsock and
1472 exec plugins. This command can be used to force a plugin (or all) to
1473 flush its values to disk.
1474 * collectd: Thresholds can now be configured to apply to one data
1475 source only, making it possible to configure different thresholds
1476 for each data source.
1477 * apache, nginx plugins: Added the possibility to disable host and/or
1479 * ascent plugin: The new ascent plugin reads and parses the statistics
1480 page of an Ascent server.

1486 sensor values via IPMI, the intelligent platform management
1488 * iptables plugin: The iptc library that is used by the iptables
1489 plugin has been added to the distribution, because it is not
1490 provided by all distributions and removed from at least one.
1491 * powerdns plugin: The new powerdns plugin reads statistics from an
1492 authoritative or a recursing PowerDNS name server.
1493 * rrdtool plugin: The size of the files generated with the default
1494 configuration has been decreased.
1495 * tail plugin: The new tail plugin can be used to gather statistics by
1496 continuously reading from log files.
1497 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1498 TeamSpeak2 server and collects statistics about the number of users
1499 and number of channels.
1500 * users plugin: Support for the statgrab library has been added.
1501 * vmem plugin: The new vmem plugin collects very detailed statistics
1502 about the virtual memory subsystem of Linux.
1504 2008-08-30, Version 4.3.4
1505 * Build system: Improved detection of and linking with the statgrab
1507 * collectd: Portability fixes, especially to determine endianess more
1509 * Various plugins: Fix format strings.
1510 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1511 again has been applied.
1512 * memcached plugin: Fix a too short timeout and a related file
1514 * memory plugin: A typo in the libstatgrab code has been fixed.
1515 * network plugin: A fix in the initialization function solves problems
1517 * nginx plugin: A thread-unsafe function has been replaced.
1518 * vserver plugin: A thread-unsafe function has been replaced.
1519 * wireless plugin: A work-around for broken wireless drivers has been
1522 2008-04-22, Version 4.3.3
1523 * build system: Improved detection of several libraries, especially if
1524 they are in non-standard paths.
1525 * build system: Portability fixes: Automatically define "_REENTRANT"
1526 if the libc expects it.
1527 * collectd: Error and warning messages have been improved.
1528 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1530 * apache plugin: Allocate new memory when reading a webpage instead of
1531 using a buffer of static size.
1532 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1534 * hddtemp plugin: Error and warning messages have been improved.
1535 * sensors plugin: Fix sensor collection for some chip types.
1537 2008-03-29, Version 4.3.2
1538 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1539 `Persist' threshold options.
1540 * collectd: Fix handling of missing values in the global value cache.
1541 * collectd: Improved error messages when parsing the configuration.
1542 * sensors plugin: Fix temperature collection with libsensors4.
1543 * unixsock plugin: Fix mixed input and output operation on streams.
1544 * wireless plugin: Fix reading noise value.
1546 2008-03-05, Version 4.3.1
1547 * exec plugin: Set supplementary group IDs.
1549 + Use `memcpy' when constructing/parsing a package to avoid
1550 alignment problems on weird architectures, such as Sparc.
1551 + Translate doubles to/from the x86 byte representation to ensure
1552 cross-platform compatibility.
1553 * ping plugin: Correct the handling of the `TTL' setting.
1554 * swap plugin: Reapply a patch for Solaris.
1555 * tcpconns plugin: Portability improvements.
1557 2008-02-18, Version 4.3.0
1558 * collectd: Notifications have been added to the daemon. Notifications
1559 are status messages that may be associated with a data instance.
1560 * collectd: Threshold checking has been added to the daemon. This
1561 means that you can configure threshold values for each data
1562 instance. If this threshold is exceeded a notification will be
1564 * collectd: The new `FQDNLookup' option tells the daemon to use the
1565 full qualified domain name as the hostname, not just the host part
1566 es returned by `gethostname(2)'.
1567 * collectd: Support for more than one `TypesDB' file has been added.
1568 This is useful when one such file is included in a package but one
1569 wants to add custom type definitions.
1570 * collectd: The `Include' config option has been expanded to handle
1571 entire directories and shell wildcards.
1572 * collectdmon: The new `collectdmon' binary detects when collectd
1573 terminates and automatically restarts it again.
1574 * csv plugin: The CSV plugin is now able to store counter values as a
1575 rate, using the `StoreRates' configuration option.
1576 * exec plugin: Handling of notifications has been added and the
1577 ability to pass arguments to the executed programs has been added.
1578 * hddtemp plugin: The new `TranslateDevicename' option lets you
1579 disable the translation from device names to major-minor-numbers.
1580 * logfile plugin: Handling of notifications has been added.
1581 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1582 domain name lookups in this plugin.
1583 * perl plugin: Many internal changes added support for handling multiple
1584 threads making the plugin reasonably usable inside collectd. The API has
1585 been extended to support notifications and export global variables to
1586 Perl plugins; callbacks now have to be identified by name rather than a
1587 pointer to a subroutine. The plugin is no longer experimental.
1588 * uuid plugin: The new UUID plugin sets the hostname to an unique
1589 identifier for this host. This is meant for setups where each client
1590 may migrate to another physical host, possibly going through one or
1591 more name changes in the process. Thanks to Richard Jones from
1592 Red Hat's Emerging Technology group for this plugin.
1593 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1594 CPU, disk and network statistics about guest systems on the same
1595 physical server. Thanks to Richard Jones from Red Hat's Emerging
1596 Technology group for this plugin.
1598 2008-04-22, Version 4.2.7
1599 * build system: Improved detection of several libraries, especially if
1600 they are in non-standard paths.
1601 * build system: Portability fixes: Automatically define "_REENTRANT"
1602 if the libc expects it.
1603 * collectd: Error and warning messages have been improved.
1604 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1606 * apache plugin: Allocate new memory when reading a webpage instead of
1607 using a buffer of static size.
1608 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1610 * hddtemp plugin: Error and warning messages have been improved.
1611 * sensors plugin: Fix sensor collection for some chip types.
1613 2008-03-29, Version 4.2.6

1615 * sensors plugin: Fix temperature collection with libsensors4.
1616 * unixsock plugin: Fix mixed input and output operation on streams.
1617 * wireless plugin: Fix reading noise value.
1619 2008-03-04, Version 4.2.5
1620 * apache plugin: Improved initialization and error messages.
1621 * exec plugin: Set supplementary group IDs.
1623 + Create separate threads for reading from the socket and parsing
1624 and dispatching incoming packets. Versions prior to this may have
1625 problems in high-load situations, where the socket receive buffers
1626 overflows, resulting in gaps in the data.
1627 + Use `memcpy' when constructing/parsing a package to avoid
1628 alignment problems on weird architectures, such as Sparc.
1629 + Translate doubles to/from the x86 byte representation to ensure
1630 cross-platform compatibility.
1631 * ping plugin: Correct the handling of the `TTL' setting.
1632 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1633 * swap plugin: Reapply a patch for Solaris.
1634 * tcpconns plugin: Portability improvements.
1636 2008-01-21, Version 4.2.4
1637 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1638 the permission on the socket as documented in the manpage. Thanks to
1639 Evgeny Chukreev for fixing this issue.
1640 * collectd: The documentation has been improved.
1642 2007-12-28, Version 4.2.3
1643 * sensors plugin: Updated the plugin to build and work with version 3
1644 of the libsensors library.
1646 2007-12-15, Version 4.2.2
1647 * nginx plugin: Incorrect comparison of strings lead to a segfault
1648 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1650 * logfile plugin: The config option `Timestamp' was handled
1651 incorrectly and basically always active. Thanks to Luke Heberling
1654 2007-11-08, Version 4.2.1
1655 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1656 enabled on the host.
1657 * snmp plugin: Fix a memory leak.
1659 2007-10-27, Version 4.2.0
1660 * collectd: The new config option `Include' lets you include other
1661 configfiles and thus split up your config into smaller parts. This
1662 may be especially interesting for the snmp plugin to keep the data
1663 definitions separate from the host definitions.
1664 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1665 (number of connections, octets and packets for each service and
1666 destination). Thanks to Sebastian Harl for this plugin.
1667 * memcached plugin: The new `memcached' plugin connects to a memcached
1668 daemon process and collects statistics of this distributed caching
1669 system. Thanks to Antony Dovgal for contributing this plugin.
1670 * nginx plugin: The new `nginx' plugin reads the status page of an
1671 nginx daemon and saves the handled connections and requests.
1672 * perl plugin: Many changes, including the added `EnableDebugger'
1673 config option which lets you debug your Perl plugins more easily.
1674 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1675 be more thread-safe otherwise by locking calls to the library.
1676 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1677 correct the values returned by SNMP-agents. If a <data> block is
1678 defined as `table' the instance is now optional. The sequence number
1679 is used as the type-instance in this case. The new `InstancePrefix'
1680 option allows to add arbitrary prefixes to the type-instance.
1681 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1682 certain TCP connections and what state they're in. This can be used
1683 to see how many connections your FTP server has to handle or how
1684 many outgoing connections your mailserver has open.
1686 2008-01-11, Version 4.1.6
1687 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1688 the permission on the socket as documented in the manpage. Thanks to

1696 of the libsensors library.
1698 2007-11-08, Version 4.1.4
1699 * Build system: Improve detection of the rrd library, especially if
1700 it's in a non-standard location.
1701 * Build system: A bug when parsing the argument for
1702 `--with-libnetsnmp' has been fixed.
1703 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1704 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1705 a deadlock or delay when shutting down the daemon.
1706 * snmp plugin: Fix a memory leak.
1708 2007-10-24, Version 4.1.3
1709 * collectd: A build issue under Solaris has been resolved by renaming
1711 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1712 be more thread-safe otherwise by locking calls to the library.
1714 2007-09-28, Version 4.1.2
1715 * apcups plugin: Fix reporting of the `load percent' data.
1716 * wireless plugin: Correct the handling of cards returning signal and
1717 noise quality as percentage.
1718 * perl plugin: Fix a possible buffer overflow in get_module_name().
1719 * build system: Further improve the detection of libraries.
1720 * netlink plugin: Build issues under some older versions of the Linux
1721 includes (i. e. Debian Sarge) have been fixed.
1722 * snmp plugin: Fix a potential segfault when a host times out. Add
1723 support for the `timeticks' type.
1725 2007-09-12, Version 4.1.1
1726 * Build system: The detection of `libnetlink' has been improved.
1727 * collectd: The documentation has been fixed in numerous places.
1728 * exec plugin: Setting the group under which to run a program has been
1730 * collectd: The `sstrerror' function was improved to work correctly
1731 with the broken GNU version of `strerror_r'.
1732 * collectd: Write an error message to STDERR when loading of a plugin
1734 * apcups plugin: Fix the `types' used to submit the values: They still
1735 has an `apcups_' prefix which doesn't work anymore.
1736 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1737 whatever the client thinks is `now'..
1739 2007-09-01, Version 4.1.0
1740 * Build system: The build system has been changed to automatically
1741 disable all plugins, which are missing dependencies. The dependency
1742 checking has been removed from the plugins themselves to remove
1744 * Flexible interval: The interval of collected data is now sent along
1745 with the data itself over the network, so that the interval-settings
1746 of server and clients no longer needs to match.
1747 * netlink plugin: The new `netlink' plugin connects to the Linux
1748 kernel using a netlink socket and uses it to query information about
1749 interfaces, qdiscs and classes.
1750 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1751 to not block data collection.
1752 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1753 network devices, such as switches, routers, thermometers, rack
1754 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1756 * unixsock plugin: Added the `LISTVAL' command.
1757 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1758 of music played with xmms.
1760 2007-09-28, Version 4.0.9
1761 * apcups plugin: Fix reporting of the `load percent' data.
1762 * wireless plugin: Correct the handling of cards returning signal and
1763 noise quality as percentage.
1764 * perl plugin: Fix a possible buffer overflow in get_module_name().
1766 2007-09-12, Version 4.0.8
1767 * collectd: The `sstrerror' function was improved to work correctly
1768 with the broken GNU version of `strerror_r'.
1769 * collectd: Write an error message to STDERR when loading of a plugin
1771 * apcups plugin: Fix the `types' used to submit the values: They still
1772 has an `apcups_' prefix which doesn't work anymore.
1773 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1774 whatever the client thinks is `now'..
1776 2007-08-26, Version 4.0.7
1777 * documentation: Some typos have been fixed and some information has
1779 * build system: Many fixes for detecting libraries in unusual places,
1780 such as on RedHat systems. The affected libraries are `libcurl',
1781 `libmysql', and `libupsclient'.
1782 * network plugin: Allow the `Port' option to be specified as a number
1783 (i. e. without quotes).
1784 * nut plugin: A fix allows linking the nut plugin against
1785 libupsclient, version >= 2.2.0.
1786 * processes plugin: Fix a potential segmentation fault.
1788 2007-07-30, Version 4.0.6
1789 * sensors plugin: Fix the ignorelist functionality: Only the `type
1790 instance' was used to match against the list, but the documentation
1791 told otherwise. This release fixes the code, so it complies with the
1793 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1794 configuration messages will end up in the logging facility.
1795 * conrtib/fedora: The contributed specfile for Fedora has been
1798 2007-07-05, Version 4.0.5
1799 * Portability: More fixes for OpenBSD have been included.
1801 2007-06-24, Version 4.0.4
1802 * cpu plugin: Fixed the Solaris code.

1804 * interface plugin: Fixed the Solaris code.
1805 * load plugin: Fixed the alternative `/proc' Linux code.
1806 * memory plugin: Fixed the Solaris code.
1807 * oconfig: Don't require `-lfl' anymore.
1809 2007-06-19, Version 4.0.3
1810 * cpu plugin: Fix the Darwin / Mac OS X code.
1811 * ping plugin: Use the return value of `getpid', not its address.
1812 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be

1814 * configure: Added `--with-nan-emulation' to aid cross compilation.
1816 2007-06-12, Version 4.0.2
1817 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1818 they're given in numerically form.
1820 2007-06-07, Version 4.0.1
1821 * iptables plugin: A bug in the configuration routine has been fixed.
1822 Setting a comment in the configfile will no longer cause a
1825 2007-06-03, Version 4.0.0
1826 * collectd: The plugin-infrastructure has been changed to allow for
1827 more types of plugins, namely `write' and `log' plugins.
1828 * collectd: The read-function has been changed to read many plugins in
1829 parallel, using threads. Thus, plugins generally need to use
1830 thread-safe functions from now on.
1831 * collectd: The '-t' command line options allows to perform syntax tests
1832 of the configuration file and exit immediately.
1833 * csv plugin: The new `csv' plugin handles output to `comma separated
1835 * rrdtool plugin: The new `rrdtool' plugin handles output to
1836 RRD-files. Data can be cached to combine multiple updates into one
1837 write to increase IO-performance.
1838 * network plugin: The new `network' plugin handles IO via the network.
1839 It implements a different, much more extensible protocol which can
1840 combine many values in one packet, decreasing the number of UDP-
1841 packets being sent. It can read from and send to the network and
1842 with the appropriate configuration even forward packets to other
1844 * unixsock plugin: The new `unixsock' plugin provides an interface to
1845 communicate with the daemon while it is running. Right now the
1846 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1848 * perl plugin: The new `perl' plugin allows you to write extensions
1849 for collectd in the scripting-language Perl.
1850 * logfile plugin: The new `logfile' plugin writes logmessages to files
1851 or STDOUT or STDERR.
1852 * syslog plugin: The new `syslog' plugin sends logmessages to the
1853 system's syslog daemon.
1854 * entropy plugin: The new `entropy' plugin collects the amount of
1855 entropy currently being available to the system.
1856 * exec plugin: The new `exec' plugin forks child processes and reads
1857 back values provided by the forked processes.
1858 * iptables plugin: The new `iptables' plugin reads counters from
1859 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1861 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1862 to Peter Holik for contributing this plugin.
1863 * nut plugin: The new `nut' plugin connects the upsd of the `network
1864 ups tools' and reads information about the connected UPS.
1865 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1866 connections) field was added by Florent Monbillard.
1867 * collectd-nagios: The new `collectd-nagios' binary queries values
1868 from collectd, parses them and exits according to Nagios-standards.
1869 * manpages: The manpages have been improved a lot.
1871 2007-09-28, Version 3.11.7
1872 * wireless plugin: Correct the handling of cards returning signal and
1873 noise quality as percentage.
1875 2007-08-31, Version 3.11.6
1876 * processes plugin: Fix a potential segmentation fault.
1878 2007-05-29, Version 3.11.5
1879 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1880 * ntpd plugin: Fix a potential buffer overflow.
1881 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1882 were accounted as `zombies'.
1884 2007-04-10, Version 3.11.4
1885 * dns plugin: Change the order of includes to make the plugin compile
1888 2007-03-30, Version 3.11.3
1889 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1890 of the unused `COLLECT_KSTAT'.
1892 2007-02-11, Version 3.11.2
1893 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1894 NULL-pointer may have been passed to `printf' which causes a
1895 segfault with some libcs.
1897 2007-02-10, Version 3.11.1
1898 * df plugin: Some wrong defines have been fixed so the plugin works
1899 under Solaris again.
1900 * dns plugin: The usage of a struct has been fixed to work with
1902 * processes plugin: Some missing defines have been added so the plugin
1903 compiles cleanly under FreeBSD and presumably other UNIXes.
1905 2006-12-22, Version 3.11.0
1906 * collectd: The new command line option `-P' makes it easier for
1907 distributors to change the location of PID-files.
1908 * collectd: The daemon shuts down faster now which makes it easier to
1909 write init.d-scripts for it.
1910 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1911 caused problems every now and then.
1912 * df plugin: New config options allow to ignore certain mountpoints,
1913 filesystem types or devices.
1914 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1915 and interprets it. It collects traffic as well as qtype, opcode and
1917 * email plugin: Sebastian Harl has contributed this plugin which
1918 counts received mails in categories (e. g. ham, spam, virus), spam
1919 score (as given by SpamAssassin) and check types.
1920 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1921 uses `mbmon' to gather information from sensors on the motherboard.
1922 * processes plugin: Collect detailed statistics for configured
1923 processes, that's process and thread count, CPU usage, resident
1924 segment size and pagefaults.
1925 * multimeter plugin: Peter Holik contributed a new plugin which
1926 queries multimeters.
1927 * sensors plugin: Lubos Stanek has put much effort into improving this
1928 plugin, including `extended naming', collection of voltage values
1929 and the possibility to ignore certain values.
1931 2006-12-21, Version 3.10.4
1932 * Max Kellermann has identified a bug in the server routine: When
1933 opening a socket fails the daemon will (re)try opening the socket in
1934 an endless loop, ultimately leading to a `EMFILE' error.
1936 2006-11-04, Version 3.10.3
1937 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1938 ntpd's reply was sent in more than one packet, the buffer size was
1939 calculated incorrectly, resulting in the reading of uninitialized or
1942 2006-11-01, Version 3.10.2
1943 * The sample config file has been improved.
1944 * Errors in the manpages have been corrected.
1945 * The ping-plugin now adds hosts during initialization, not during
1946 startup. This speeds up startup when no network connectivity is
1947 available. Also, the hosts are being added later when the network is
1949 * Improved BSD-support for the df-plugin.
1950 * Fixed syntax errors in the swap-plugin for Mac OS X.
1951 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1953 * Don't disable the mysql-plugin if connecting to the database fails
1954 during initialization. Instead, try again in increasing intervals.
1956 2006-07-19, Version 3.10.1
1957 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1958 the apcups cannot be reached, unconnected sockets will pile up and
1959 eventually lead to `Too many open files' errors.
1961 2006-07-09, Version 3.10.0
1962 * The `disk' plugin has been ported to Darwin.
1963 * The `battery' plugin should work on many Apple computers now.
1964 * The `traffic' plugin can now ignore certain interfaces. Also,
1965 statistics for sent/received packets and errors have been added.

1967 to Anthony Gialluca for contributing this plugin and providing me
1968 with a test environment :)
1969 * A plugin for monitoring an NTP instance and the local clock drift
1972 2006-06-25, Version 3.9.4
1973 * The Solaris code in the `swap' plugin has been changed to reflect
1974 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1976 * The debugging system has been fixed to work with the Sun libc.
1977 * When built without librrd the variable `operating_mode' could be
1978 uninitialized. Thanks to David Elliot for reporting the bug.
1980 2006-06-01, Version 3.9.3
1981 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1982 operating systems also profit from the changes, but I wasn't able to
1984 * Changed the build system to find the netinet-includes under FreeBSD
1985 and therefore successfully build the `liboping' library there.
1987 2006-05-09, Version 3.9.2
1988 * Applied a patch to the `liboping' library. Due to a bug in the
1989 sequence checking the `ping' plugin stopped working after
1990 approximately 7.6 days.
1992 2006-05-09, Version 3.8.5
1993 * Applied a patch to the `liboping' library. Due to a bug in the
1994 sequence checking the `ping' plugin stopped working after
1995 approximately 7.6 days.
1997 2006-04-21, Version 3.9.1
1998 * Build issues with Solaris and possible other architectures have been
2000 * Problems when building the `apache'-plugin without `libcurl' have
2002 * A bug in the `ping' plugin has been fixed. Sorry folks.
2004 2006-04-02, Version 3.9.0
2005 * A plugin to monitor the Apache webserver has been added.
2006 <http://httpd.apache.org/>
2007 * A plugin to collect statistics about virtual servers using VServer.
2008 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2010 * A plugin for wireless LAN cards has been added. It monitors signal
2011 strength, link quality and noise ratio..
2012 * A plugin for Apple hardware sensors has been added.
2013 * An option to compile collectd with different `step' and `heartbeat'
2014 settings has been added. The size of RRAs is no longer static but
2015 calculated based on the settings for `step' and `width'.
2016 * The `ping' plugin can now be configured to use a certain TTL.
2017 * A plugin to monitor the hardware sensors of Apple computers has been
2019 * The plugins `cpu', `memory', `processes' and `traffic' have been
2020 ported to Mach/Darwin (Mac OS X).
2021 * The `log mode' has been contributed by Christophe Kalt. It writes
2022 the data into text files rather than RRD files.
2024 2006-04-09, Version 3.8.4
2025 * Applied patch by Vincent Stehlé which improves the disk-name
2026 resolution in the `hddtemp' plugin for Linux systems.
2028 2006-04-02, Version 3.8.3
2029 * Applied a patch by James Byers: The MySQL plugin was not working
2030 with MySQL 5.0.2 or later.
2032 2006-03-14, Version 3.8.2
2033 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2034 the GNU libc, because it points to `/etc/fstab' rather than
2037 2006-03-13, Version 3.8.1
2038 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2039 * Fixes in the debian `postinst' and `init.d' scripts.
2041 2006-03-09, Version 3.8.0
2042 * The `ping' plugin no longer uses `libping' but a self written
2043 library named `liboping'. With this library it's possible to ping
2044 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2046 2006-02-18, Version 3.7.2
2047 * A simple bug in the `battery' plugin has been fixed. It should now
2048 work with ACPI based batteries as well. Thanks to Sebastian for
2050 * Fixing a bug that prevented collectd to be built without librrd.
2051 Thanks to Werner Heuser for reporting it.
2053 2006-02-04, Version 3.7.1
2054 * The new network code has been improved to build with older versions

2057 to Tommie Gannert for this patch.
2059 2006-01-30, Version 3.7.0
2060 * The `battery' plugin has been added. It collects information about
2062 * The MySQL plugin has been improved: It now writes two more RRD
2063 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2064 * The `cpufreq' plugin now reads another file since the file it did
2065 read so far causes much overhead in the kernel. Also, you need root
2066 to read the old file, but not to read the new one.
2067 * The `hddtemp' plugin can now be configured to connect to another
2068 address and/or port than localhost.
2069 * The `df' plugin now prefers `statvfs' over `statfs'.
2070 * The network code has been rewritten. collectd now supports unicast
2071 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2072 be set in the configfile.
2074 2006-01-24, Version 3.6.2
2075 * Due to a bug in the configfile handling collectd wouldn't start in
2076 client mode. This released fixes this.
2078 2006-01-20, Version 3.6.1
2079 * Due to a bug in `configure.in' all modules and the binary were
2080 linked against `libmysqlclient'. This issue is solved by this
2083 2006-01-17, Version 3.6.0
2084 * A config file has been added. This allows for loading only specific
2086 * A `df' plugin has been added.
2087 * A `mysql' plugin has been added.
2088 * The `ping' plugin doesn't entirely give up hope when a socket error
2089 occurred, but will back of and increase the intervals between tries.
2091 2006-01-21, Version 3.5.2
2092 * Fixed yet another bug in the signal handling.. Stupid typo..
2093 * Improved the ping plugin to not give up on socket errors (backport
2096 2005-12-18, Version 3.5.1
2097 * The PID-file is now deleted correctly when shutting down the daemon.
2098 * SIGINT and SIGTERM are now handled correctly.
2100 2005-12-16, Version 3.5.0 (Revision 326)
2101 * A bug in the `load' module under Solaris has been fixed.
2102 * The `users' module has been contributed by Sebastian Harl. It counts
2103 currently logged in users.
2104 * The CPU module now works under FreeBSD without the use of
2105 `libstatgrab', however SMP support is missing.
2106 * The default directories for the RRD files and the PID file now
2107 depend on the compile time setting of `localstatedir'.
2109 2005-11-15, Version 3.4.0 (Revision 236)
2110 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2111 from gentoo's bugzilla for writing the patch.
2112 * The build dependency for librrd has been removed. Binaries built
2113 without librrd are client-only and will multicast their value as
2114 with the `-c' argument.
2115 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2116 * The newly introduced `-f' switch prevents daemon initialization
2117 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2118 Barcellos for this patch.
2120 2005-11-04, Version 3.3.0 (Revision 216)
2121 * New modules have been added:
2122 - `serial', for monitoring traffic on the serial interfaces
2123 - `nfs', for graphing NFS procedure calls
2124 - `tape', traffic from/to tape devices
2125 * The memory.rrd now accepts more than 4Gig of memory.
2127 2005-10-26, Version 3.2.0 (Revision 200)
2128 * Support for graphing the processes has been added (thanks to Lyonel

2131 between polls up to one day.
2132 * The init.d files have been improved.
2133 * Problems with the spec file have been fixed.
2135 2005-10-16, Version 3.1.0 (Revision 194)
2136 * Added the `setsid' syscall to the startup code.
2137 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2139 2005-09-30, Version 3.0.0 (Revision 184)
2140 * The ability to send/receive data to/from the network (think
2141 multicast) has been added.
2142 * Modules have been split up into shared libraries can be loaded at
2143 runtime. The biggest advantage is that the core program doesn't need
2144 to be linked against an external library.
2145 * A patch by George Kargiotakis has been applied: It fixes the sensors
2146 behaviour then more than one sensor is being queried.
2148 2005-09-16, Version 2.1.0 (Revision 172)
2149 * A module for swap statistics has been added.
2151 2005-09-09, Version 2.0.0 (Revision 135)
2152 * Filenames can no longer be configured at program startup. The only
2153 options as of this version are the directory and ping hosts.
2154 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2155 Soft-IRQ statistics are added to `System'.
2156 * Diskstats now collect read and write bytes, not sectors.
2157 * Ping statistics can now be collected for more than one host. There
2158 is no default any more: If no host is given no host will be pinged.
2159 * A self-written patch for libping has been applied so it builds
2162 2005-09-01, Version 1.8.1 (Revision 123)
2163 * Much improved configure-script: libraries and features may now be
2165 * More detailed warnings/error messages when RRD update fails.
2167 2005-08-29, Version 1.8.0:
2168 * Support for collecting disk statistics under Solaris.
2170 2005-08-25, Version 1.7.0:
2171 * Support for libstatgrab[1] for load, memory usage and network
2172 traffic. CPU- and disk-usage are not (yet) supported, since
2173 libstatgrab returns insufficient information. I will contact the
2175 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2176 aren't necessarily counted linear which is now handled correctly.
2177 [1]: http://www.i-scream.org/libstatgrab/
2179 2005-08-21, Version 1.6.0:
2180 * Basic support for Solaris: System load and cpu-usage can be
2181 collected under Solaris, too. Other stats will follow later.
2182 * Many fixes in the autoconf-script
2183 * Collection/Museum scripts have been added under contrib/museum
2184 * collectd may now be started in unprivileged mode, though ping
2185 statistics will not work.
2187 2005-07-17, Version 1.5.1:
2188 * Diskstats-RRDs now use major/minor for naming. Some systems have
2189 weird strings as disk-names..
2191 2005-07-17, Version 1.5:
2192 * A new module, diskstats, has been added. It collects information
2193 about the disks and partitions.
2195 2005-07-11, Version 1.4.2:
2196 * The meminfo module has been changed to work with more platforms
2197 and/or kernel versions.
2199 2005-07-10, Version 1.4.1: Correct traffic stats
2200 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2201 forgot to correct when I changed that module.
2203 2005-07-09, Version 1.4: More traffic stats
2204 * Traffic is now collected for all interfaces that can be found
2205 * Temperature-statistics are read from lm-sensors if available
2207 2005-07-08, Version 1.3: CPU stats
2208 * Collecting CPU statistics now
2210 2005-07-12, Version 1.2: Using syslog
2211 * collectd is now using the syslog facility to report errors, warnings
2213 * The default directory is now /var/db/collectd
2215 2005-07-10, Version 1.1: Minor changes
2216 * Nothing really useful to say ;)
2218 2005-07-09, Version 1.0: Initial Version
2219 * The following modules are provided:
