511 Hess for reporting this bug.
512 * iptables plugin: Support for the new libiptc API has been added.
513 Thanks to Sebastian Harl for the patch. The build system has been
514 updated to the plugin only includes the shipped header files when it
515 is linked with the shipped library, too.
516 * java plugin: Delay creating the JVM until after the daemon has
517 forked. The JVM internally creates threads that are lost when
518 forking. This means that Java-based plugins are now configured
519 during the init-phase, i. e. later than other plugins.
520 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
521 to Alan Pevec for the patch.
522 * network plugin: Fix the handling of the “CacheFlush” option: The
523 value was assigned to a wrong variable. The initialization of the
524 gcrypt library, which is used for signing / encrypting traffic, has
525 been fixed. Thanks to Luke Heberling for the patch.
526 * powerdns plugin: Set a timeout when reading data from the datagram
527 socket. Handling of the “LocalSocket” option has been fixed. An
528 incorrectly used “type” has been corrected. Thanks to Luke Heberling

539 for reporting the bug.
540 * ping plugin: Link the plugin with libm.
542 2009-06-02, Version 4.7.1
543 * Build system: Detection of Java has been improved and missing
544 details have been added to the configuration summary. Support for
545 libtool 2.2 has been added.
546 * collectd: Two bugs with the threshold checking have been fixed. The
547 first one prevented thresholds to be checked at all, the second one
548 caused wrong behavior with the persistency option. Thanks to Andrés
549 J. Díaz for fixing these problems.
550 * collectd: Handling of the `Include' configuration option has been
552 * rrdtool plugin: Make sure initialization is run only once. This
553 resolves problems under Solaris and potentially other systems.

572 multicast traffic from Ganglia's gmond daemon.
573 * java plugin: The new java plugin exports the collectd API to Java,
574 making it possible to write extensions to collectd in Java.
575 * memcachec plugin: The new memcachec plugin queries data from a
576 memcached daemon and parses it similar to the cURL plugin. Thanks to
577 Doug MacEachern for the initial code.
578 * memcached plugin: Support for connections over UNIX domain sockets
579 has been added. Thanks to Franck Lombardi for the patch.

598 * onewire plugin: The new `Interval' option allows collecting
599 information from OneWire sensors at arbitrary intervals.
600 * ping plugin: Support for collecting the drop rate and standard
601 deviation of round-trip times has been added.
602 * uptime plugin: The new uptime plugin can collect the server's
603 uptime. Thanks to Marco Chiappero for the patch.
605 2009-09-10, Version 4.6.5
606 * collectd: Remove old values when a cache entry is marked as missing.
607 This way the “GETVAL” command of the UnixSock plugin doesn't return

664 name which prevented this match to be used as documented. Thanks to
665 Bruno Prémont for finding this problem.
666 * bind plugin: Fix collection of the cached RR sets. The number of RR
667 sets currently in the cache was collected as a counter value, which
668 is nonsense. Thanks to Bruno Prémont for implementing this.
669 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
670 primarily BSDs, don't take it well and crash.
671 * oracle plugin: Portability to 64 bit systems has been improved.
672 * postgresql plugin: The default configuration has been improved.
673 * rrdtool plugin: Fix a possible race condition: If the network plugin
674 is brought and dispatches a value before the rrdtool plugin is
675 initialized, the daemon may crash.
677 2009-02-22, Version 4.6.1
678 * collectd: Many documentation fixes.

688 user to use `matches' and `targets' to control value processing.
689 * collectd: The new `-T' command line argument allows more in-depth
690 testing of a configuration. Thanks to Doug MacEachern for the patch.
691 * collectd-nagios: The Nagios integration command has been updated to
692 use libcollectdclient. The `percentage' aggregation function has
693 been added. Thanks to Fabian Linzberger for the patch.

709 example for native OpenBSD support, has been added. Thanks to Simon
710 Kuhnle for the patch.
711 * csv plugin: Make it possible to write values to STDOUT instead of
712 files. This is meant for testing purposes mostly. The output written
713 to STDOUT is compatible with the exec plugin. Thanks to Doug
714 MacEachern for the patch.
715 * curl plugin: This new plugin can be used to read web pages and parse
716 them using the same mechanism that's used in the tail plugin.
717 * dbi plugin: This new plugin allows you to connect to a variety of
718 relational databases and use SQL to gather custom statistics from
719 it. It is similar to the already existing PostgreSQL plugin but uses
720 libdbi to communicate with the database(s).
721 * interface plugin: Use the ignorelist framework when selecting /
722 ignoring interfaces. This allows one to use regular expressions to
723 select interfaces, too.
724 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
725 Thanks to Bruno Prémont for this patch.
726 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

742 allowing plugins to register `matches' and `targets'.
743 * postgresql plugin: The preferred configuration syntax has been
744 updated to be in line with the syntax used by the new dbi and oracle
745 plugins. The compatibility code for the old syntax is present.
746 Support for the new `Result' blocks and the interval parameter has
748 * processes plugin: Stacksize and virtual memory usage statistics have
749 been added. Portability fixes.
750 * rrdcached plugin: This new plugin uses the (still in development)
751 RRD accelerator daemon, rrdcached. This daemon works very similar to
752 the original rrdtool plugin of collectd, but adds some more nice
754 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
757 2009-05-09, Version 4.5.4
758 * Build system, various plugins: Many build fixes for FreeBSD,

788 code. Thanks to "thated" for reporting this.
790 2009-01-02, Version 4.5.2
791 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
792 file may be in both locations, especially when the database was
793 installed in a non-standard path. Thanks to Dusty Doris for
795 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
796 Solaris, in the configure script automatically.
797 * build system, tcpconns plugin: Check for `kvm_nlist' and
798 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
799 library with similar functions to the BSD variant, but doesn't
800 provide these necessary functions.
801 * collectd.conf(5): Various fixes and clarifications.
802 * collectd: Remove a GNUism (unnamed unions), thus improving
804 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.

806 * dns plugin: Fix a portability problem with NetBSD.
807 * filecount plugin: Fix an off-by-one error. This error may cause a
809 * network plugin: Fix the handling of `type' in the network protocol.
810 Due to a programming mistake, only 4 or 8 bytes would be copied to a
811 much larger buffer. This caused the `type' to be transferred much
812 more often than necessary. In some cases, e. g. the `cpu' and
813 `cpufreq' plugins being used at the same time, data may be corrupted
814 in those files. Thanks to Bruno Prémont for debugging and reporting
816 * processes plugin: Fix a possible segmentation fault when specifying
817 invalid configuration options.
818 * unixsock plugin: Make sure the initialization function is run only
819 once. This resolves a file descriptor leak under systems which run
820 the initialization more than once, such as Solaris.
822 2008-10-16, Version 4.5.1
823 * build system: Change `--enable-<plugin>' to abort with an error if
824 dependencies are not met. Thanks to Bruno Prémont for the patch.
825 Also, the poisoning of various string functions has been restricted
827 * collectd: Fix a memory leak in the global value cache. With every
828 *missing* value a couple of bytes would be leaked. Another memory
829 leak in the configuration handling code has been fixed. Thanks to
830 Niraj Tolia for reporting these issues.
831 * collectd: Fix an off-by-one error in the ignorelist functionality.
832 When using regular expressions, the last character would be missing,
833 possibly matching differently from what one would expect.
834 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
836 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
837 Linzberger for reporting the bug.
838 * iptables plugin: Fix an off-by-one error. If a string was just one
839 character too long, it was truncated instead of reporting an error.
840 * network plugin: Fix a memory leak in the configuration handling
841 code. Thanks to Niraj Tolia for reporting this issue.
842 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
843 * postgresql plugin: Don't reopen connection during reinitialization.
844 This fixes a bug under Solaris and potentially other platforms.

846 leaks. Thanks to ``Admin'' for reporting these bugs.
847 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
849 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes

867 such as temperatures, from sensors connected to the computer via the
869 * perl plugin: Improved synchronized access to internal data structures
870 and fixed a possible dead-lock.
871 * perl plugin: Added the ability to flush certain identifiers and marked
872 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
874 * perl plugin: Added the ability to configure Perl plugins.

896 Due to a programming mistake, only 4 or 8 bytes would be copied to a
897 much larger buffer. This caused the `type' to be transferred much
898 more often than necessary. In some cases, e. g. the `cpu' and
899 `cpufreq' plugins being used at the same time, data may be corrupted
900 in those files. Thanks to Bruno Prémont for debugging and reporting
902 * unixsock plugin: Make sure the initialization function is run only

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

982 sensor values via IPMI, the intelligent platform management
984 * iptables plugin: The iptc library that is used by the iptables
985 plugin has been added to the distribution, because it is not
986 provided by all distributions and removed from at least one.
987 * powerdns plugin: The new powerdns plugin reads statistics from an
988 authoritative or a recursing PowerDNS name server.
989 * rrdtool plugin: The size of the files generated with the default
990 configuration has been decreased.
991 * tail plugin: The new tail plugin can be used to gather statistics by
992 continuously reading from log files.
993 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
994 TeamSpeak2 server and collects statistics about the number of users
995 and number of channels.
996 * users plugin: Support for the statgrab library has been added.
997 * vmem plugin: The new vmem plugin collects very detailed statistics
998 about the virtual memory subsystem of Linux.
1000 2008-08-30, Version 4.3.4
1001 * Build system: Improved detection of and linking with the statgrab
1003 * collectd: Portability fixes, especially to determine endianess more
1005 * Various plugins: Fix format strings.

1014 * vserver plugin: A thread-unsafe function has been replaced.
1015 * wireless plugin: A work-around for broken wireless drivers has been
1018 2008-04-22, Version 4.3.3
1019 * build system: Improved detection of several libraries, especially if
1020 they are in non-standard paths.
1021 * build system: Portability fixes: Automatically define "_REENTRANT"
1022 if the libc expects it.
1023 * collectd: Error and warning messages have been improved.
1024 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1026 * apache plugin: Allocate new memory when reading a webpage instead of
1027 using a buffer of static size.
1028 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1030 * hddtemp plugin: Error and warning messages have been improved.
1031 * sensors plugin: Fix sensor collection for some chip types.
1033 2008-03-29, Version 4.3.2
1034 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1035 `Persist' threshold options.
1036 * collectd: Fix handling of missing values in the global value cache.
1037 * collectd: Improved error messages when parsing the configuration.
1038 * sensors plugin: Fix temperature collection with libsensors4.
1039 * unixsock plugin: Fix mixed input and output operation on streams.
1040 * wireless plugin: Fix reading noise value.
1042 2008-03-05, Version 4.3.1
1043 * exec plugin: Set supplementary group IDs.
1045 + Use `memcpy' when constructing/parsing a package to avoid
1046 alignment problems on weird architectures, such as Sparc.
1047 + Translate doubles to/from the x86 byte representation to ensure
1048 cross-platform compatibility.
1049 * ping plugin: Correct the handling of the `TTL' setting.
1050 * swap plugin: Reapply a patch for Solaris.
1051 * tcpconns plugin: Portability improvements.
1053 2008-02-18, Version 4.3.0
1054 * collectd: Notifications have been added to the daemon. Notifications
1055 are status messages that may be associated with a data instance.
1056 * collectd: Threshold checking has been added to the daemon. This
1057 means that you can configure threshold values for each data
1058 instance. If this threshold is exceeded a notification will be
1060 * collectd: The new `FQDNLookup' option tells the daemon to use the
1061 full qualified domain name as the hostname, not just the host part
1062 es returned by `gethostname(2)'.
1063 * collectd: Support for more than one `TypesDB' file has been added.
1064 This is useful when one such file is included in a package but one
1065 wants to add custom type definitions.
1066 * collectd: The `Include' config option has been expanded to handle
1067 entire directories and shell wildcards.
1068 * collectdmon: The new `collectdmon' binary detects when collectd
1069 terminates and automatically restarts it again.
1070 * csv plugin: The CSV plugin is now able to store counter values as a
1071 rate, using the `StoreRates' configuration option.
1072 * exec plugin: Handling of notifications has been added and the
1073 ability to pass arguments to the executed programs has been added.
1074 * hddtemp plugin: The new `TranslateDevicename' option lets you
1075 disable the translation from device names to major-minor-numbers.
1076 * logfile plugin: Handling of notifications has been added.
1077 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1078 domain name lookups in this plugin.
1079 * perl plugin: Many internal changes added support for handling multiple
1080 threads making the plugin reasonably usable inside collectd. The API has
1081 been extended to support notifications and export global variables to
1082 Perl plugins; callbacks now have to be identified by name rather than a
1083 pointer to a subroutine. The plugin is no longer experimental.
1084 * uuid plugin: The new UUID plugin sets the hostname to an unique
1085 identifier for this host. This is meant for setups where each client
1086 may migrate to another physical host, possibly going through one or
1087 more name changes in the process. Thanks to Richard Jones from
1088 Red Hat's Emerging Technology group for this plugin.
1089 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1090 CPU, disk and network statistics about guest systems on the same
1091 physical server. Thanks to Richard Jones from Red Hat's Emerging
1092 Technology group for this plugin.
1094 2008-04-22, Version 4.2.7
1095 * build system: Improved detection of several libraries, especially if
1096 they are in non-standard paths.
1097 * build system: Portability fixes: Automatically define "_REENTRANT"
1098 if the libc expects it.
1099 * collectd: Error and warning messages have been improved.
1100 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1102 * apache plugin: Allocate new memory when reading a webpage instead of
1103 using a buffer of static size.
1104 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1106 * hddtemp plugin: Error and warning messages have been improved.
1107 * sensors plugin: Fix sensor collection for some chip types.
1109 2008-03-29, Version 4.2.6
1110 * collectd: Improved error messages when parsing the configuration.
1111 * sensors plugin: Fix temperature collection with libsensors4.
1112 * unixsock plugin: Fix mixed input and output operation on streams.
1113 * wireless plugin: Fix reading noise value.
1115 2008-03-04, Version 4.2.5
1116 * apache plugin: Improved initialization and error messages.
1117 * exec plugin: Set supplementary group IDs.
1119 + Create separate threads for reading from the socket and parsing
1120 and dispatching incoming packets. Versions prior to this may have
1121 problems in high-load situations, where the socket receive buffers
1122 overflows, resulting in gaps in the data.
1123 + Use `memcpy' when constructing/parsing a package to avoid
1124 alignment problems on weird architectures, such as Sparc.
1125 + Translate doubles to/from the x86 byte representation to ensure
1126 cross-platform compatibility.
1127 * ping plugin: Correct the handling of the `TTL' setting.
1128 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1129 * swap plugin: Reapply a patch for Solaris.
1130 * tcpconns plugin: Portability improvements.
1132 2008-01-21, Version 4.2.4
1133 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1134 the permission on the socket as documented in the manpage. Thanks to
1135 Evgeny Chukreev for fixing this issue.
1136 * collectd: The documentation has been improved.
1138 2007-12-28, Version 4.2.3
1139 * sensors plugin: Updated the plugin to build and work with version 3
1140 of the libsensors library.
1142 2007-12-15, Version 4.2.2
1143 * nginx plugin: Incorrect comparison of strings lead to a segfault
1144 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1146 * logfile plugin: The config option `Timestamp' was handled
1147 incorrectly and basically always active. Thanks to Luke Heberling
1150 2007-11-08, Version 4.2.1
1151 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1152 enabled on the host.
1153 * snmp plugin: Fix a memory leak.
1155 2007-10-27, Version 4.2.0
1156 * collectd: The new config option `Include' lets you include other
1157 configfiles and thus split up your config into smaller parts. This
1158 may be especially interesting for the snmp plugin to keep the data
1159 definitions separate from the host definitions.
1160 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1161 (number of connections, octets and packets for each service and
1162 destination). Thanks to Sebastian Harl for this plugin.
1163 * memcached plugin: The new `memcached' plugin connects to a memcached
1164 daemon process and collects statistics of this distributed caching
1165 system. Thanks to Antony Dovgal for contributing this plugin.
1166 * nginx plugin: The new `nginx' plugin reads the status page of an
1167 nginx daemon and saves the handled connections and requests.
1168 * perl plugin: Many changes, including the added `EnableDebugger'
1169 config option which lets you debug your Perl plugins more easily.
1170 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1171 be more thread-safe otherwise by locking calls to the library.
1172 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1173 correct the values returned by SNMP-agents. If a <data> block is
1174 defined as `table' the instance is now optional. The sequence number
1175 is used as the type-instance in this case. The new `InstancePrefix'
1176 option allows to add arbitrary prefixes to the type-instance.
1177 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1178 certain TCP connections and what state they're in. This can be used
1179 to see how many connections your FTP server has to handle or how
1180 many outgoing connections your mailserver has open.
1182 2008-01-11, Version 4.1.6
1183 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1184 the permission on the socket as documented in the manpage. Thanks to

1192 of the libsensors library.
1194 2007-11-08, Version 4.1.4
1195 * Build system: Improve detection of the rrd library, especially if
1196 it's in a non-standard location.
1197 * Build system: A bug when parsing the argument for
1198 `--with-libnetsnmp' has been fixed.
1199 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1200 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1201 a deadlock or delay when shutting down the daemon.
1202 * snmp plugin: Fix a memory leak.
1204 2007-10-24, Version 4.1.3
1205 * collectd: A build issue under Solaris has been resolved by renaming
1207 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1208 be more thread-safe otherwise by locking calls to the library.
1210 2007-09-28, Version 4.1.2
1211 * apcups plugin: Fix reporting of the `load percent' data.
1212 * wireless plugin: Correct the handling of cards returning signal and
1213 noise quality as percentage.
1214 * perl plugin: Fix a possible buffer overflow in get_module_name().
1215 * build system: Further improve the detection of libraries.
1216 * netlink plugin: Build issues under some older versions of the Linux
1217 includes (i. e. Debian Sarge) have been fixed.
1218 * snmp plugin: Fix a potential segfault when a host times out. Add
1219 support for the `timeticks' type.
1221 2007-09-12, Version 4.1.1
1222 * Build system: The detection of `libnetlink' has been improved.
1223 * collectd: The documentation has been fixed in numerous places.
1224 * exec plugin: Setting the group under which to run a program has been
1226 * collectd: The `sstrerror' function was improved to work correctly
1227 with the broken GNU version of `strerror_r'.
1228 * collectd: Write an error message to STDERR when loading of a plugin
1230 * apcups plugin: Fix the `types' used to submit the values: They still
1231 has an `apcups_' prefix which doesn't work anymore.
1232 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1233 whatever the client thinks is `now'..
1235 2007-09-01, Version 4.1.0
1236 * Build system: The build system has been changed to automatically
1237 disable all plugins, which are missing dependencies. The dependency
1238 checking has been removed from the plugins themselves to remove
1240 * Flexible interval: The interval of collected data is now sent along
1241 with the data itself over the network, so that the interval-settings
1242 of server and clients no longer needs to match.
1243 * netlink plugin: The new `netlink' plugin connects to the Linux
1244 kernel using a netlink socket and uses it to query information about
1245 interfaces, qdiscs and classes.
1246 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1247 to not block data collection.
1248 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1249 network devices, such as switches, routers, thermometers, rack
1250 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1252 * unixsock plugin: Added the `LISTVAL' command.
1253 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1254 of music played with xmms.
1256 2007-09-28, Version 4.0.9
1257 * apcups plugin: Fix reporting of the `load percent' data.
1258 * wireless plugin: Correct the handling of cards returning signal and
1259 noise quality as percentage.
1260 * perl plugin: Fix a possible buffer overflow in get_module_name().
1262 2007-09-12, Version 4.0.8
1263 * collectd: The `sstrerror' function was improved to work correctly
1264 with the broken GNU version of `strerror_r'.
1265 * collectd: Write an error message to STDERR when loading of a plugin
1267 * apcups plugin: Fix the `types' used to submit the values: They still
1268 has an `apcups_' prefix which doesn't work anymore.
1269 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1270 whatever the client thinks is `now'..
1272 2007-08-26, Version 4.0.7
1273 * documentation: Some typos have been fixed and some information has
1275 * build system: Many fixes for detecting libraries in unusual places,
1276 such as on RedHat systems. The affected libraries are `libcurl',
1277 `libmysql', and `libupsclient'.
1278 * network plugin: Allow the `Port' option to be specified as a number
1279 (i. e. without quotes).
1280 * nut plugin: A fix allows linking the nut plugin against
1281 libupsclient, version >= 2.2.0.
1282 * processes plugin: Fix a potential segmentation fault.
1284 2007-07-30, Version 4.0.6
1285 * sensors plugin: Fix the ignorelist functionality: Only the `type
1286 instance' was used to match against the list, but the documentation
1287 told otherwise. This release fixes the code, so it complies with the
1289 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1290 configuration messages will end up in the logging facility.
1291 * conrtib/fedora: The contributed specfile for Fedora has been
1294 2007-07-05, Version 4.0.5
1295 * Portability: More fixes for OpenBSD have been included.
1297 2007-06-24, Version 4.0.4
1298 * cpu plugin: Fixed the Solaris code.
1299 * dns plugin: Fixed a build issue for OpenBSD.
1300 * interface plugin: Fixed the Solaris code.
1301 * load plugin: Fixed the alternative `/proc' Linux code.
1302 * memory plugin: Fixed the Solaris code.
1303 * oconfig: Don't require `-lfl' anymore.
1305 2007-06-19, Version 4.0.3
1306 * cpu plugin: Fix the Darwin / Mac OS X code.
1307 * ping plugin: Use the return value of `getpid', not its address.
1308 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1309 initialized correctly.
1310 * configure: Added `--with-nan-emulation' to aid cross compilation.
1312 2007-06-12, Version 4.0.2
1313 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1314 they're given in numerically form.
1316 2007-06-07, Version 4.0.1
1317 * iptables plugin: A bug in the configuration routine has been fixed.
1318 Setting a comment in the configfile will no longer cause a
1321 2007-06-03, Version 4.0.0
1322 * collectd: The plugin-infrastructure has been changed to allow for
1323 more types of plugins, namely `write' and `log' plugins.
1324 * collectd: The read-function has been changed to read many plugins in
1325 parallel, using threads. Thus, plugins generally need to use
1326 thread-safe functions from now on.
1327 * collectd: The '-t' command line options allows to perform syntax tests
1328 of the configuration file and exit immediately.
1329 * csv plugin: The new `csv' plugin handles output to `comma separated
1331 * rrdtool plugin: The new `rrdtool' plugin handles output to
1332 RRD-files. Data can be cached to combine multiple updates into one
1333 write to increase IO-performance.
1334 * network plugin: The new `network' plugin handles IO via the network.
1335 It implements a different, much more extensible protocol which can
1336 combine many values in one packet, decreasing the number of UDP-
1337 packets being sent. It can read from and send to the network and
1338 with the appropriate configuration even forward packets to other
1340 * unixsock plugin: The new `unixsock' plugin provides an interface to
1341 communicate with the daemon while it is running. Right now the
1342 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1344 * perl plugin: The new `perl' plugin allows you to write extensions
1345 for collectd in the scripting-language Perl.
1346 * logfile plugin: The new `logfile' plugin writes logmessages to files
1347 or STDOUT or STDERR.
1348 * syslog plugin: The new `syslog' plugin sends logmessages to the
1349 system's syslog daemon.
1350 * entropy plugin: The new `entropy' plugin collects the amount of
1351 entropy currently being available to the system.
1352 * exec plugin: The new `exec' plugin forks child processes and reads
1353 back values provided by the forked processes.
1354 * iptables plugin: The new `iptables' plugin reads counters from
1355 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1357 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1358 to Peter Holik for contributing this plugin.
1359 * nut plugin: The new `nut' plugin connects the upsd of the `network
1360 ups tools' and reads information about the connected UPS.
1361 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1362 connections) field was added by Florent Monbillard.
1363 * collectd-nagios: The new `collectd-nagios' binary queries values
1364 from collectd, parses them and exits according to Nagios-standards.
1365 * manpages: The manpages have been improved a lot.
1367 2007-09-28, Version 3.11.7
1368 * wireless plugin: Correct the handling of cards returning signal and
1369 noise quality as percentage.
1371 2007-08-31, Version 3.11.6
1372 * processes plugin: Fix a potential segmentation fault.
1374 2007-05-29, Version 3.11.5
1375 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1376 * ntpd plugin: Fix a potential buffer overflow.
1377 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1378 were accounted as `zombies'.
1380 2007-04-10, Version 3.11.4
1381 * dns plugin: Change the order of includes to make the plugin compile
1384 2007-03-30, Version 3.11.3
1385 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1386 of the unused `COLLECT_KSTAT'.
1388 2007-02-11, Version 3.11.2
1389 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1390 NULL-pointer may have been passed to `printf' which causes a
1391 segfault with some libcs.
1393 2007-02-10, Version 3.11.1
1394 * df plugin: Some wrong defines have been fixed so the plugin works
1395 under Solaris again.
1396 * dns plugin: The usage of a struct has been fixed to work with
1398 * processes plugin: Some missing defines have been added so the plugin
1399 compiles cleanly under FreeBSD and presumably other UNIXes.
1401 2006-12-22, Version 3.11.0
1402 * collectd: The new command line option `-P' makes it easier for
1403 distributors to change the location of PID-files.
1404 * collectd: The daemon shuts down faster now which makes it easier to
1405 write init.d-scripts for it.
1406 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1407 caused problems every now and then.
1408 * df plugin: New config options allow to ignore certain mountpoints,
1409 filesystem types or devices.
1410 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1411 and interprets it. It collects traffic as well as qtype, opcode and
1413 * email plugin: Sebastian Harl has contributed this plugin which
1414 counts received mails in categories (e. g. ham, spam, virus), spam
1415 score (as given by SpamAssassin) and check types.
1416 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1417 uses `mbmon' to gather information from sensors on the motherboard.
1418 * processes plugin: Collect detailed statistics for configured
1419 processes, that's process and thread count, CPU usage, resident
1420 segment size and pagefaults.
1421 * multimeter plugin: Peter Holik contributed a new plugin which
1422 queries multimeters.
1423 * sensors plugin: Lubos Stanek has put much effort into improving this
1424 plugin, including `extended naming', collection of voltage values
1425 and the possibility to ignore certain values.
1427 2006-12-21, Version 3.10.4
1428 * Max Kellermann has identified a bug in the server routine: When
1429 opening a socket fails the daemon will (re)try opening the socket in
1430 an endless loop, ultimately leading to a `EMFILE' error.
1432 2006-11-04, Version 3.10.3
1433 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1434 ntpd's reply was sent in more than one packet, the buffer size was
1435 calculated incorrectly, resulting in the reading of uninitialized or
1438 2006-11-01, Version 3.10.2
1439 * The sample config file has been improved.
1440 * Errors in the manpages have been corrected.
1441 * The ping-plugin now adds hosts during initialization, not during
1442 startup. This speeds up startup when no network connectivity is
1443 available. Also, the hosts are being added later when the network is
1445 * Improved BSD-support for the df-plugin.
1446 * Fixed syntax errors in the swap-plugin for Mac OS X.
1447 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1449 * Don't disable the mysql-plugin if connecting to the database fails
1450 during initialization. Instead, try again in increasing intervals.
1452 2006-07-19, Version 3.10.1
1453 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1454 the apcups cannot be reached, unconnected sockets will pile up and
1455 eventually lead to `Too many open files' errors.
1457 2006-07-09, Version 3.10.0
1458 * The `disk' plugin has been ported to Darwin.
1459 * The `battery' plugin should work on many Apple computers now.
1460 * The `traffic' plugin can now ignore certain interfaces. Also,
1461 statistics for sent/received packets and errors have been added.
1462 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1463 to Anthony Gialluca for contributing this plugin and providing me
1464 with a test environment :)
1465 * A plugin for monitoring an NTP instance and the local clock drift
1468 2006-06-25, Version 3.9.4
1469 * The Solaris code in the `swap' plugin has been changed to reflect
1470 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1472 * The debugging system has been fixed to work with the Sun libc.
1473 * When built without librrd the variable `operating_mode' could be
1474 uninitialized. Thanks to David Elliot for reporting the bug.
1476 2006-06-01, Version 3.9.3
1477 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1478 operating systems also profit from the changes, but I wasn't able to
1480 * Changed the build system to find the netinet-includes under FreeBSD
1481 and therefore successfully build the `liboping' library there.
1483 2006-05-09, Version 3.9.2
1484 * Applied a patch to the `liboping' library. Due to a bug in the
1485 sequence checking the `ping' plugin stopped working after
1486 approximately 7.6 days.
1488 2006-05-09, Version 3.8.5
1489 * Applied a patch to the `liboping' library. Due to a bug in the
1490 sequence checking the `ping' plugin stopped working after
1491 approximately 7.6 days.
1493 2006-04-21, Version 3.9.1
1494 * Build issues with Solaris and possible other architectures have been
1496 * Problems when building the `apache'-plugin without `libcurl' have
1498 * A bug in the `ping' plugin has been fixed. Sorry folks.
1500 2006-04-02, Version 3.9.0
1501 * A plugin to monitor the Apache webserver has been added.
1502 <http://httpd.apache.org/>
1503 * A plugin to collect statistics about virtual servers using VServer.
1504 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1506 * A plugin for wireless LAN cards has been added. It monitors signal
1507 strength, link quality and noise ratio..
1508 * A plugin for Apple hardware sensors has been added.
1509 * An option to compile collectd with different `step' and `heartbeat'
1510 settings has been added. The size of RRAs is no longer static but
1511 calculated based on the settings for `step' and `width'.
1512 * The `ping' plugin can now be configured to use a certain TTL.
1513 * A plugin to monitor the hardware sensors of Apple computers has been
1515 * The plugins `cpu', `memory', `processes' and `traffic' have been
1516 ported to Mach/Darwin (Mac OS X).
1517 * The `log mode' has been contributed by Christophe Kalt. It writes
1518 the data into text files rather than RRD files.
1520 2006-04-09, Version 3.8.4
1521 * Applied patch by Vincent Stehlé which improves the disk-name
1522 resolution in the `hddtemp' plugin for Linux systems.
1524 2006-04-02, Version 3.8.3
1525 * Applied a patch by James Byers: The MySQL plugin was not working
1526 with MySQL 5.0.2 or later.
1528 2006-03-14, Version 3.8.2
1529 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1530 the GNU libc, because it points to `/etc/fstab' rather than
1533 2006-03-13, Version 3.8.1
1534 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1535 * Fixes in the debian `postinst' and `init.d' scripts.
1537 2006-03-09, Version 3.8.0
1538 * The `ping' plugin no longer uses `libping' but a self written
1539 library named `liboping'. With this library it's possible to ping
1540 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1542 2006-02-18, Version 3.7.2
1543 * A simple bug in the `battery' plugin has been fixed. It should now
1544 work with ACPI based batteries as well. Thanks to Sebastian for
1546 * Fixing a bug that prevented collectd to be built without librrd.
1547 Thanks to Werner Heuser for reporting it.
1549 2006-02-04, Version 3.7.1
1550 * The new network code has been improved to build with older versions
1552 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1553 to Tommie Gannert for this patch.
1555 2006-01-30, Version 3.7.0
1556 * The `battery' plugin has been added. It collects information about
1558 * The MySQL plugin has been improved: It now writes two more RRD
1559 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1560 * The `cpufreq' plugin now reads another file since the file it did
1561 read so far causes much overhead in the kernel. Also, you need root
1562 to read the old file, but not to read the new one.
1563 * The `hddtemp' plugin can now be configured to connect to another
1564 address and/or port than localhost.
1565 * The `df' plugin now prefers `statvfs' over `statfs'.
1566 * The network code has been rewritten. collectd now supports unicast
1567 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1568 be set in the configfile.
1570 2006-01-24, Version 3.6.2
1571 * Due to a bug in the configfile handling collectd wouldn't start in
1572 client mode. This released fixes this.
1574 2006-01-20, Version 3.6.1
1575 * Due to a bug in `configure.in' all modules and the binary were
1576 linked against `libmysqlclient'. This issue is solved by this
1579 2006-01-17, Version 3.6.0
1580 * A config file has been added. This allows for loading only specific
1582 * A `df' plugin has been added.
1583 * A `mysql' plugin has been added.
1584 * The `ping' plugin doesn't entirely give up hope when a socket error
1585 occurred, but will back of and increase the intervals between tries.
1587 2006-01-21, Version 3.5.2
1588 * Fixed yet another bug in the signal handling.. Stupid typo..
1589 * Improved the ping plugin to not give up on socket errors (backport
1592 2005-12-18, Version 3.5.1
1593 * The PID-file is now deleted correctly when shutting down the daemon.
1594 * SIGINT and SIGTERM are now handled correctly.
1596 2005-12-16, Version 3.5.0 (Revision 326)
1597 * A bug in the `load' module under Solaris has been fixed.
1598 * The `users' module has been contributed by Sebastian Harl. It counts
1599 currently logged in users.
1600 * The CPU module now works under FreeBSD without the use of
1601 `libstatgrab', however SMP support is missing.
1602 * The default directories for the RRD files and the PID file now
1603 depend on the compile time setting of `localstatedir'.
1605 2005-11-15, Version 3.4.0 (Revision 236)
1606 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1607 from gentoo's bugzilla for writing the patch.
1608 * The build dependency for librrd has been removed. Binaries built
1609 without librrd are client-only and will multicast their value as
1610 with the `-c' argument.
1611 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1612 * The newly introduced `-f' switch prevents daemon initialization
1613 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1614 Barcellos for this patch.
1616 2005-11-04, Version 3.3.0 (Revision 216)
1617 * New modules have been added:
1618 - `serial', for monitoring traffic on the serial interfaces
1619 - `nfs', for graphing NFS procedure calls
1620 - `tape', traffic from/to tape devices
1621 * The memory.rrd now accepts more than 4Gig of memory.
1623 2005-10-26, Version 3.2.0 (Revision 200)
1624 * Support for graphing the processes has been added (thanks to Lyonel
1626 * If reading from hddtemp fails collectd will increase the time
1627 between polls up to one day.
1628 * The init.d files have been improved.
1629 * Problems with the spec file have been fixed.
1631 2005-10-16, Version 3.1.0 (Revision 194)
1632 * Added the `setsid' syscall to the startup code.
1633 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1635 2005-09-30, Version 3.0.0 (Revision 184)
1636 * The ability to send/receive data to/from the network (think
1637 multicast) has been added.
1638 * Modules have been split up into shared libraries can be loaded at
1639 runtime. The biggest advantage is that the core program doesn't need
1640 to be linked against an external library.
1641 * A patch by George Kargiotakis has been applied: It fixes the sensors
1642 behaviour then more than one sensor is being queried.
1644 2005-09-16, Version 2.1.0 (Revision 172)
1645 * A module for swap statistics has been added.
1647 2005-09-09, Version 2.0.0 (Revision 135)
1648 * Filenames can no longer be configured at program startup. The only
1649 options as of this version are the directory and ping hosts.
1650 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1651 Soft-IRQ statistics are added to `System'.
1652 * Diskstats now collect read and write bytes, not sectors.
1653 * Ping statistics can now be collected for more than one host. There
1654 is no default any more: If no host is given no host will be pinged.
1655 * A self-written patch for libping has been applied so it builds
1658 2005-09-01, Version 1.8.1 (Revision 123)
1659 * Much improved configure-script: libraries and features may now be
1661 * More detailed warnings/error messages when RRD update fails.
1663 2005-08-29, Version 1.8.0:
1664 * Support for collecting disk statistics under Solaris.
1666 2005-08-25, Version 1.7.0:
1667 * Support for libstatgrab[1] for load, memory usage and network
1668 traffic. CPU- and disk-usage are not (yet) supported, since
1669 libstatgrab returns insufficient information. I will contact the
1671 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1672 aren't necessarily counted linear which is now handled correctly.
1673 [1]: http://www.i-scream.org/libstatgrab/
1675 2005-08-21, Version 1.6.0:
1676 * Basic support for Solaris: System load and cpu-usage can be
1677 collected under Solaris, too. Other stats will follow later.
1678 * Many fixes in the autoconf-script
1679 * Collection/Museum scripts have been added under contrib/museum
1680 * collectd may now be started in unprivileged mode, though ping
1681 statistics will not work.
1683 2005-07-17, Version 1.5.1:
1684 * Diskstats-RRDs now use major/minor for naming. Some systems have
1685 weird strings as disk-names..
1687 2005-07-17, Version 1.5:
1688 * A new module, diskstats, has been added. It collects information
1689 about the disks and partitions.
1691 2005-07-11, Version 1.4.2:
1692 * The meminfo module has been changed to work with more platforms
1693 and/or kernel versions.
1695 2005-07-10, Version 1.4.1: Correct traffic stats
1696 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1697 forgot to correct when I changed that module.
1699 2005-07-09, Version 1.4: More traffic stats
1700 * Traffic is now collected for all interfaces that can be found
1701 * Temperature-statistics are read from lm-sensors if available
1703 2005-07-08, Version 1.3: CPU stats
1704 * Collecting CPU statistics now
1706 2005-07-12, Version 1.2: Using syslog
1707 * collectd is now using the syslog facility to report errors, warnings
1709 * The default directory is now /var/db/collectd
1711 2005-07-10, Version 1.1: Minor changes
1712 * Nothing really useful to say ;)
1714 2005-07-09, Version 1.0: Initial Version
1715 * The following modules are provided:
