500 forked. The JVM internally creates threads that are lost when
501 forking. This means that Java-based plugins are now configured
502 during the init-phase, i. e. later than other plugins.
503 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
504 to Alan Pevec for the patch.
505 * network plugin: Fix the handling of the “CacheFlush” option: The

527 details have been added to the configuration summary. Support for
528 libtool 2.2 has been added.
529 * collectd: Two bugs with the threshold checking have been fixed. The
530 first one prevented thresholds to be checked at all, the second one
531 caused wrong behavior with the persistency option. Thanks to Andrés
532 J. Díaz for fixing these problems.
533 * collectd: Handling of the `Include' configuration option has been
535 * rrdtool plugin: Make sure initialization is run only once. This

583 * ping plugin: Support for collecting the drop rate and standard
584 deviation of round-trip times has been added.
585 * uptime plugin: The new uptime plugin can collect the server's
586 uptime. Thanks to Marco Chiappero for the patch.
588 2009-09-10, Version 4.6.5
589 * collectd: Remove old values when a cache entry is marked as missing.
590 This way the “GETVAL” command of the UnixSock plugin doesn't return
591 old, no longer valid values when this happens. Thanks to Andrés J.
593 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
594 to follow redirects. Thanks to Joey Hess for reporting this bug.

647 name which prevented this match to be used as documented. Thanks to
648 Bruno Prémont for finding this problem.
649 * bind plugin: Fix collection of the cached RR sets. The number of RR
650 sets currently in the cache was collected as a counter value, which
651 is nonsense. Thanks to Bruno Prémont for implementing this.
652 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
653 primarily BSDs, don't take it well and crash.
654 * oracle plugin: Portability to 64 bit systems has been improved.
655 * postgresql plugin: The default configuration has been improved.
656 * rrdtool plugin: Fix a possible race condition: If the network plugin

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

697 MacEachern for the patch.
698 * curl plugin: This new plugin can be used to read web pages and parse
699 them using the same mechanism that's used in the tail plugin.
700 * dbi plugin: This new plugin allows you to connect to a variety of
701 relational databases and use SQL to gather custom statistics from
702 it. It is similar to the already existing PostgreSQL plugin but uses
703 libdbi to communicate with the database(s).
704 * interface plugin: Use the ignorelist framework when selecting /
705 ignoring interfaces. This allows one to use regular expressions to
706 select interfaces, too.
707 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
708 Thanks to Bruno Prémont for this patch.
709 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

727 updated to be in line with the syntax used by the new dbi and oracle
728 plugins. The compatibility code for the old syntax is present.
729 Support for the new `Result' blocks and the interval parameter has
731 * processes plugin: Stacksize and virtual memory usage statistics have
732 been added. Portability fixes.
733 * rrdcached plugin: This new plugin uses the (still in development)
734 RRD accelerator daemon, rrdcached. This daemon works very similar to
735 the original rrdtool plugin of collectd, but adds some more nice
737 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
740 2009-05-09, Version 4.5.4
741 * Build system, various plugins: Many build fixes for FreeBSD,

771 code. Thanks to "thated" for reporting this.
773 2009-01-02, Version 4.5.2
774 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
775 file may be in both locations, especially when the database was
776 installed in a non-standard path. Thanks to Dusty Doris for

779 Solaris, in the configure script automatically.
780 * build system, tcpconns plugin: Check for `kvm_nlist' and
781 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
782 library with similar functions to the BSD variant, but doesn't
783 provide these necessary functions.

792 * network plugin: Fix the handling of `type' in the network protocol.
793 Due to a programming mistake, only 4 or 8 bytes would be copied to a
794 much larger buffer. This caused the `type' to be transferred much
795 more often than necessary. In some cases, e. g. the `cpu' and
796 `cpufreq' plugins being used at the same time, data may be corrupted
797 in those files. Thanks to Bruno Prémont for debugging and reporting
799 * processes plugin: Fix a possible segmentation fault when specifying
800 invalid configuration options.
801 * unixsock plugin: Make sure the initialization function is run only
802 once. This resolves a file descriptor leak under systems which run

805 2008-10-16, Version 4.5.1
806 * build system: Change `--enable-<plugin>' to abort with an error if
807 dependencies are not met. Thanks to Bruno Prémont for the patch.
808 Also, the poisoning of various string functions has been restricted
810 * collectd: Fix a memory leak in the global value cache. With every

812 leak in the configuration handling code has been fixed. Thanks to
813 Niraj Tolia for reporting these issues.
814 * collectd: Fix an off-by-one error in the ignorelist functionality.
815 When using regular expressions, the last character would be missing,
816 possibly matching differently from what one would expect.
817 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
819 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
820 Linzberger for reporting the bug.
821 * iptables plugin: Fix an off-by-one error. If a string was just one
822 character too long, it was truncated instead of reporting an error.
823 * network plugin: Fix a memory leak in the configuration handling
824 code. Thanks to Niraj Tolia for reporting this issue.
825 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

990 again has been applied.
991 * memcached plugin: Fix a too short timeout and a related file
993 * memory plugin: A typo in the libstatgrab code has been fixed.
994 * network plugin: A fix in the initialization function solves problems
996 * nginx plugin: A thread-unsafe function has been replaced.
997 * vserver plugin: A thread-unsafe function has been replaced.
998 * wireless plugin: A work-around for broken wireless drivers has been
1001 2008-04-22, Version 4.3.3
1002 * build system: Improved detection of several libraries, especially if
1003 they are in non-standard paths.
1004 * build system: Portability fixes: Automatically define "_REENTRANT"
1005 if the libc expects it.
1006 * collectd: Error and warning messages have been improved.
1007 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1009 * apache plugin: Allocate new memory when reading a webpage instead of
1010 using a buffer of static size.
1011 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1013 * hddtemp plugin: Error and warning messages have been improved.
1014 * sensors plugin: Fix sensor collection for some chip types.
1016 2008-03-29, Version 4.3.2
1017 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1018 `Persist' threshold options.
1019 * collectd: Fix handling of missing values in the global value cache.
1020 * collectd: Improved error messages when parsing the configuration.
1021 * sensors plugin: Fix temperature collection with libsensors4.
1022 * unixsock plugin: Fix mixed input and output operation on streams.
1023 * wireless plugin: Fix reading noise value.
1025 2008-03-05, Version 4.3.1
1026 * exec plugin: Set supplementary group IDs.
1028 + Use `memcpy' when constructing/parsing a package to avoid
1029 alignment problems on weird architectures, such as Sparc.
1030 + Translate doubles to/from the x86 byte representation to ensure
1031 cross-platform compatibility.
1032 * ping plugin: Correct the handling of the `TTL' setting.
1033 * swap plugin: Reapply a patch for Solaris.
1034 * tcpconns plugin: Portability improvements.
1036 2008-02-18, Version 4.3.0
1037 * collectd: Notifications have been added to the daemon. Notifications
1038 are status messages that may be associated with a data instance.
1039 * collectd: Threshold checking has been added to the daemon. This
1040 means that you can configure threshold values for each data
1041 instance. If this threshold is exceeded a notification will be
1043 * collectd: The new `FQDNLookup' option tells the daemon to use the
1044 full qualified domain name as the hostname, not just the host part
1045 es returned by `gethostname(2)'.
1046 * collectd: Support for more than one `TypesDB' file has been added.
1047 This is useful when one such file is included in a package but one
1048 wants to add custom type definitions.
1049 * collectd: The `Include' config option has been expanded to handle
1050 entire directories and shell wildcards.
1051 * collectdmon: The new `collectdmon' binary detects when collectd
1052 terminates and automatically restarts it again.
1053 * csv plugin: The CSV plugin is now able to store counter values as a
1054 rate, using the `StoreRates' configuration option.
1055 * exec plugin: Handling of notifications has been added and the
1056 ability to pass arguments to the executed programs has been added.
1057 * hddtemp plugin: The new `TranslateDevicename' option lets you
1058 disable the translation from device names to major-minor-numbers.
1059 * logfile plugin: Handling of notifications has been added.
1060 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1061 domain name lookups in this plugin.
1062 * perl plugin: Many internal changes added support for handling multiple
1063 threads making the plugin reasonably usable inside collectd. The API has
1064 been extended to support notifications and export global variables to
1065 Perl plugins; callbacks now have to be identified by name rather than a
1066 pointer to a subroutine. The plugin is no longer experimental.
1067 * uuid plugin: The new UUID plugin sets the hostname to an unique
1068 identifier for this host. This is meant for setups where each client
1069 may migrate to another physical host, possibly going through one or
1070 more name changes in the process. Thanks to Richard Jones from
1071 Red Hat's Emerging Technology group for this plugin.
1072 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1073 CPU, disk and network statistics about guest systems on the same
1074 physical server. Thanks to Richard Jones from Red Hat's Emerging
1075 Technology group for this plugin.
1077 2008-04-22, Version 4.2.7
1078 * build system: Improved detection of several libraries, especially if
1079 they are in non-standard paths.
1080 * build system: Portability fixes: Automatically define "_REENTRANT"
1081 if the libc expects it.
1082 * collectd: Error and warning messages have been improved.
1083 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1085 * apache plugin: Allocate new memory when reading a webpage instead of
1086 using a buffer of static size.
1087 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1089 * hddtemp plugin: Error and warning messages have been improved.
1090 * sensors plugin: Fix sensor collection for some chip types.
1092 2008-03-29, Version 4.2.6
1093 * collectd: Improved error messages when parsing the configuration.
1094 * sensors plugin: Fix temperature collection with libsensors4.
1095 * unixsock plugin: Fix mixed input and output operation on streams.
1096 * wireless plugin: Fix reading noise value.
1098 2008-03-04, Version 4.2.5
1099 * apache plugin: Improved initialization and error messages.
1100 * exec plugin: Set supplementary group IDs.
1102 + Create separate threads for reading from the socket and parsing
1103 and dispatching incoming packets. Versions prior to this may have
1104 problems in high-load situations, where the socket receive buffers
1105 overflows, resulting in gaps in the data.
1106 + Use `memcpy' when constructing/parsing a package to avoid
1107 alignment problems on weird architectures, such as Sparc.
1108 + Translate doubles to/from the x86 byte representation to ensure
1109 cross-platform compatibility.
1110 * ping plugin: Correct the handling of the `TTL' setting.
1111 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1112 * swap plugin: Reapply a patch for Solaris.
1113 * tcpconns plugin: Portability improvements.
1115 2008-01-21, Version 4.2.4
1116 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1117 the permission on the socket as documented in the manpage. Thanks to
1118 Evgeny Chukreev for fixing this issue.
1119 * collectd: The documentation has been improved.
1121 2007-12-28, Version 4.2.3
1122 * sensors plugin: Updated the plugin to build and work with version 3
1123 of the libsensors library.
1125 2007-12-15, Version 4.2.2
1126 * nginx plugin: Incorrect comparison of strings lead to a segfault
1127 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1129 * logfile plugin: The config option `Timestamp' was handled
1130 incorrectly and basically always active. Thanks to Luke Heberling
1133 2007-11-08, Version 4.2.1
1134 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1135 enabled on the host.
1136 * snmp plugin: Fix a memory leak.
1138 2007-10-27, Version 4.2.0
1139 * collectd: The new config option `Include' lets you include other
1140 configfiles and thus split up your config into smaller parts. This
1141 may be especially interesting for the snmp plugin to keep the data
1142 definitions separate from the host definitions.
1143 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1144 (number of connections, octets and packets for each service and
1145 destination). Thanks to Sebastian Harl for this plugin.
1146 * memcached plugin: The new `memcached' plugin connects to a memcached
1147 daemon process and collects statistics of this distributed caching
1148 system. Thanks to Antony Dovgal for contributing this plugin.
1149 * nginx plugin: The new `nginx' plugin reads the status page of an
1150 nginx daemon and saves the handled connections and requests.
1151 * perl plugin: Many changes, including the added `EnableDebugger'
1152 config option which lets you debug your Perl plugins more easily.
1153 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1154 be more thread-safe otherwise by locking calls to the library.
1155 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1156 correct the values returned by SNMP-agents. If a <data> block is
1157 defined as `table' the instance is now optional. The sequence number
1158 is used as the type-instance in this case. The new `InstancePrefix'
1159 option allows to add arbitrary prefixes to the type-instance.
1160 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1161 certain TCP connections and what state they're in. This can be used
1162 to see how many connections your FTP server has to handle or how
1163 many outgoing connections your mailserver has open.
1165 2008-01-11, Version 4.1.6
1166 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1167 the permission on the socket as documented in the manpage. Thanks to
1168 Evgeny Chukreev for fixing this issue.
1169 * collectd: The documentation has been improved.
1171 2007-12-27, Version 4.1.5
1172 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1174 * sensors plugin: Updated the plugin to build and work with version 3
1175 of the libsensors library.
1177 2007-11-08, Version 4.1.4
1178 * Build system: Improve detection of the rrd library, especially if
1179 it's in a non-standard location.
1180 * Build system: A bug when parsing the argument for
1181 `--with-libnetsnmp' has been fixed.
1182 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1183 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1184 a deadlock or delay when shutting down the daemon.
1185 * snmp plugin: Fix a memory leak.
1187 2007-10-24, Version 4.1.3
1188 * collectd: A build issue under Solaris has been resolved by renaming
1190 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1191 be more thread-safe otherwise by locking calls to the library.
1193 2007-09-28, Version 4.1.2
1194 * apcups plugin: Fix reporting of the `load percent' data.
1195 * wireless plugin: Correct the handling of cards returning signal and
1196 noise quality as percentage.
1197 * perl plugin: Fix a possible buffer overflow in get_module_name().
1198 * build system: Further improve the detection of libraries.
1199 * netlink plugin: Build issues under some older versions of the Linux
1200 includes (i. e. Debian Sarge) have been fixed.
1201 * snmp plugin: Fix a potential segfault when a host times out. Add
1202 support for the `timeticks' type.
1204 2007-09-12, Version 4.1.1
1205 * Build system: The detection of `libnetlink' has been improved.
1206 * collectd: The documentation has been fixed in numerous places.
1207 * exec plugin: Setting the group under which to run a program has been
1209 * collectd: The `sstrerror' function was improved to work correctly
1210 with the broken GNU version of `strerror_r'.
1211 * collectd: Write an error message to STDERR when loading of a plugin
1213 * apcups plugin: Fix the `types' used to submit the values: They still
1214 has an `apcups_' prefix which doesn't work anymore.
1215 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1216 whatever the client thinks is `now'..
1218 2007-09-01, Version 4.1.0
1219 * Build system: The build system has been changed to automatically
1220 disable all plugins, which are missing dependencies. The dependency
1221 checking has been removed from the plugins themselves to remove
1223 * Flexible interval: The interval of collected data is now sent along
1224 with the data itself over the network, so that the interval-settings
1225 of server and clients no longer needs to match.
1226 * netlink plugin: The new `netlink' plugin connects to the Linux
1227 kernel using a netlink socket and uses it to query information about
1228 interfaces, qdiscs and classes.
1229 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1230 to not block data collection.
1231 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1232 network devices, such as switches, routers, thermometers, rack
1233 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1235 * unixsock plugin: Added the `LISTVAL' command.
1236 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1237 of music played with xmms.
1239 2007-09-28, Version 4.0.9
1240 * apcups plugin: Fix reporting of the `load percent' data.
1241 * wireless plugin: Correct the handling of cards returning signal and
1242 noise quality as percentage.
1243 * perl plugin: Fix a possible buffer overflow in get_module_name().
1245 2007-09-12, Version 4.0.8
1246 * collectd: The `sstrerror' function was improved to work correctly
1247 with the broken GNU version of `strerror_r'.
1248 * collectd: Write an error message to STDERR when loading of a plugin
1250 * apcups plugin: Fix the `types' used to submit the values: They still
1251 has an `apcups_' prefix which doesn't work anymore.
1252 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1253 whatever the client thinks is `now'..
1255 2007-08-26, Version 4.0.7
1256 * documentation: Some typos have been fixed and some information has
1258 * build system: Many fixes for detecting libraries in unusual places,
1259 such as on RedHat systems. The affected libraries are `libcurl',
1260 `libmysql', and `libupsclient'.
1261 * network plugin: Allow the `Port' option to be specified as a number
1262 (i. e. without quotes).
1263 * nut plugin: A fix allows linking the nut plugin against
1264 libupsclient, version >= 2.2.0.
1265 * processes plugin: Fix a potential segmentation fault.
1267 2007-07-30, Version 4.0.6
1268 * sensors plugin: Fix the ignorelist functionality: Only the `type
1269 instance' was used to match against the list, but the documentation
1270 told otherwise. This release fixes the code, so it complies with the
1272 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1273 configuration messages will end up in the logging facility.
1274 * conrtib/fedora: The contributed specfile for Fedora has been
1277 2007-07-05, Version 4.0.5
1278 * Portability: More fixes for OpenBSD have been included.
1280 2007-06-24, Version 4.0.4
1281 * cpu plugin: Fixed the Solaris code.
1282 * dns plugin: Fixed a build issue for OpenBSD.
1283 * interface plugin: Fixed the Solaris code.
1284 * load plugin: Fixed the alternative `/proc' Linux code.
1285 * memory plugin: Fixed the Solaris code.
1286 * oconfig: Don't require `-lfl' anymore.
1288 2007-06-19, Version 4.0.3
1289 * cpu plugin: Fix the Darwin / Mac OS X code.
1290 * ping plugin: Use the return value of `getpid', not its address.
1291 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1292 initialized correctly.
1293 * configure: Added `--with-nan-emulation' to aid cross compilation.
1295 2007-06-12, Version 4.0.2
1296 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1297 they're given in numerically form.
1299 2007-06-07, Version 4.0.1
1300 * iptables plugin: A bug in the configuration routine has been fixed.
1301 Setting a comment in the configfile will no longer cause a
1304 2007-06-03, Version 4.0.0
1305 * collectd: The plugin-infrastructure has been changed to allow for
1306 more types of plugins, namely `write' and `log' plugins.
1307 * collectd: The read-function has been changed to read many plugins in
1308 parallel, using threads. Thus, plugins generally need to use
1309 thread-safe functions from now on.
1310 * collectd: The '-t' command line options allows to perform syntax tests
1311 of the configuration file and exit immediately.
1312 * csv plugin: The new `csv' plugin handles output to `comma separated
1314 * rrdtool plugin: The new `rrdtool' plugin handles output to
1315 RRD-files. Data can be cached to combine multiple updates into one
1316 write to increase IO-performance.
1317 * network plugin: The new `network' plugin handles IO via the network.
1318 It implements a different, much more extensible protocol which can
1319 combine many values in one packet, decreasing the number of UDP-
1320 packets being sent. It can read from and send to the network and
1321 with the appropriate configuration even forward packets to other
1323 * unixsock plugin: The new `unixsock' plugin provides an interface to
1324 communicate with the daemon while it is running. Right now the
1325 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1327 * perl plugin: The new `perl' plugin allows you to write extensions
1328 for collectd in the scripting-language Perl.
1329 * logfile plugin: The new `logfile' plugin writes logmessages to files
1330 or STDOUT or STDERR.
1331 * syslog plugin: The new `syslog' plugin sends logmessages to the
1332 system's syslog daemon.
1333 * entropy plugin: The new `entropy' plugin collects the amount of
1334 entropy currently being available to the system.
1335 * exec plugin: The new `exec' plugin forks child processes and reads
1336 back values provided by the forked processes.
1337 * iptables plugin: The new `iptables' plugin reads counters from
1338 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1340 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1341 to Peter Holik for contributing this plugin.
1342 * nut plugin: The new `nut' plugin connects the upsd of the `network
1343 ups tools' and reads information about the connected UPS.
1344 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1345 connections) field was added by Florent Monbillard.
1346 * collectd-nagios: The new `collectd-nagios' binary queries values
1347 from collectd, parses them and exits according to Nagios-standards.
1348 * manpages: The manpages have been improved a lot.
1350 2007-09-28, Version 3.11.7
1351 * wireless plugin: Correct the handling of cards returning signal and
1352 noise quality as percentage.
1354 2007-08-31, Version 3.11.6
1355 * processes plugin: Fix a potential segmentation fault.
1357 2007-05-29, Version 3.11.5
1358 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1359 * ntpd plugin: Fix a potential buffer overflow.
1360 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1361 were accounted as `zombies'.
1363 2007-04-10, Version 3.11.4
1364 * dns plugin: Change the order of includes to make the plugin compile
1367 2007-03-30, Version 3.11.3
1368 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1369 of the unused `COLLECT_KSTAT'.
1371 2007-02-11, Version 3.11.2
1372 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1373 NULL-pointer may have been passed to `printf' which causes a
1374 segfault with some libcs.
1376 2007-02-10, Version 3.11.1
1377 * df plugin: Some wrong defines have been fixed so the plugin works
1378 under Solaris again.
1379 * dns plugin: The usage of a struct has been fixed to work with
1381 * processes plugin: Some missing defines have been added so the plugin
1382 compiles cleanly under FreeBSD and presumably other UNIXes.
1384 2006-12-22, Version 3.11.0
1385 * collectd: The new command line option `-P' makes it easier for
1386 distributors to change the location of PID-files.
1387 * collectd: The daemon shuts down faster now which makes it easier to
1388 write init.d-scripts for it.
1389 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1390 caused problems every now and then.
1391 * df plugin: New config options allow to ignore certain mountpoints,
1392 filesystem types or devices.
1393 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1394 and interprets it. It collects traffic as well as qtype, opcode and
1396 * email plugin: Sebastian Harl has contributed this plugin which
1397 counts received mails in categories (e. g. ham, spam, virus), spam
1398 score (as given by SpamAssassin) and check types.
1399 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1400 uses `mbmon' to gather information from sensors on the motherboard.
1401 * processes plugin: Collect detailed statistics for configured
1402 processes, that's process and thread count, CPU usage, resident
1403 segment size and pagefaults.
1404 * multimeter plugin: Peter Holik contributed a new plugin which
1405 queries multimeters.
1406 * sensors plugin: Lubos Stanek has put much effort into improving this
1407 plugin, including `extended naming', collection of voltage values
1408 and the possibility to ignore certain values.
1410 2006-12-21, Version 3.10.4
1411 * Max Kellermann has identified a bug in the server routine: When
1412 opening a socket fails the daemon will (re)try opening the socket in
1413 an endless loop, ultimately leading to a `EMFILE' error.
1415 2006-11-04, Version 3.10.3
1416 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1417 ntpd's reply was sent in more than one packet, the buffer size was
1418 calculated incorrectly, resulting in the reading of uninitialized or
1421 2006-11-01, Version 3.10.2
1422 * The sample config file has been improved.
1423 * Errors in the manpages have been corrected.
1424 * The ping-plugin now adds hosts during initialization, not during
1425 startup. This speeds up startup when no network connectivity is
1426 available. Also, the hosts are being added later when the network is
1428 * Improved BSD-support for the df-plugin.
1429 * Fixed syntax errors in the swap-plugin for Mac OS X.
1430 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1432 * Don't disable the mysql-plugin if connecting to the database fails
1433 during initialization. Instead, try again in increasing intervals.
1435 2006-07-19, Version 3.10.1
1436 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1437 the apcups cannot be reached, unconnected sockets will pile up and
1438 eventually lead to `Too many open files' errors.
1440 2006-07-09, Version 3.10.0
1441 * The `disk' plugin has been ported to Darwin.
1442 * The `battery' plugin should work on many Apple computers now.
1443 * The `traffic' plugin can now ignore certain interfaces. Also,
1444 statistics for sent/received packets and errors have been added.
1445 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1446 to Anthony Gialluca for contributing this plugin and providing me
1447 with a test environment :)
1448 * A plugin for monitoring an NTP instance and the local clock drift
1451 2006-06-25, Version 3.9.4
1452 * The Solaris code in the `swap' plugin has been changed to reflect
1453 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1455 * The debugging system has been fixed to work with the Sun libc.
1456 * When built without librrd the variable `operating_mode' could be
1457 uninitialized. Thanks to David Elliot for reporting the bug.
1459 2006-06-01, Version 3.9.3
1460 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1461 operating systems also profit from the changes, but I wasn't able to
1463 * Changed the build system to find the netinet-includes under FreeBSD
1464 and therefore successfully build the `liboping' library there.
1466 2006-05-09, Version 3.9.2
1467 * Applied a patch to the `liboping' library. Due to a bug in the
1468 sequence checking the `ping' plugin stopped working after
1469 approximately 7.6 days.
1471 2006-05-09, Version 3.8.5
1472 * Applied a patch to the `liboping' library. Due to a bug in the
1473 sequence checking the `ping' plugin stopped working after
1474 approximately 7.6 days.
1476 2006-04-21, Version 3.9.1
1477 * Build issues with Solaris and possible other architectures have been
1479 * Problems when building the `apache'-plugin without `libcurl' have
1481 * A bug in the `ping' plugin has been fixed. Sorry folks.
1483 2006-04-02, Version 3.9.0
1484 * A plugin to monitor the Apache webserver has been added.
1485 <http://httpd.apache.org/>
1486 * A plugin to collect statistics about virtual servers using VServer.
1487 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1489 * A plugin for wireless LAN cards has been added. It monitors signal
1490 strength, link quality and noise ratio..
1491 * A plugin for Apple hardware sensors has been added.
1492 * An option to compile collectd with different `step' and `heartbeat'
1493 settings has been added. The size of RRAs is no longer static but
1494 calculated based on the settings for `step' and `width'.
1495 * The `ping' plugin can now be configured to use a certain TTL.
1496 * A plugin to monitor the hardware sensors of Apple computers has been
1498 * The plugins `cpu', `memory', `processes' and `traffic' have been
1499 ported to Mach/Darwin (Mac OS X).
1500 * The `log mode' has been contributed by Christophe Kalt. It writes
1501 the data into text files rather than RRD files.
1503 2006-04-09, Version 3.8.4
1504 * Applied patch by Vincent Stehlé which improves the disk-name
1505 resolution in the `hddtemp' plugin for Linux systems.
1507 2006-04-02, Version 3.8.3
1508 * Applied a patch by James Byers: The MySQL plugin was not working
1509 with MySQL 5.0.2 or later.
1511 2006-03-14, Version 3.8.2
1512 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1513 the GNU libc, because it points to `/etc/fstab' rather than
1516 2006-03-13, Version 3.8.1
1517 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1518 * Fixes in the debian `postinst' and `init.d' scripts.
1520 2006-03-09, Version 3.8.0
1521 * The `ping' plugin no longer uses `libping' but a self written
1522 library named `liboping'. With this library it's possible to ping
1523 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1525 2006-02-18, Version 3.7.2
1526 * A simple bug in the `battery' plugin has been fixed. It should now
1527 work with ACPI based batteries as well. Thanks to Sebastian for
1529 * Fixing a bug that prevented collectd to be built without librrd.
1530 Thanks to Werner Heuser for reporting it.
1532 2006-02-04, Version 3.7.1
1533 * The new network code has been improved to build with older versions
1535 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1536 to Tommie Gannert for this patch.
1538 2006-01-30, Version 3.7.0
1539 * The `battery' plugin has been added. It collects information about
1541 * The MySQL plugin has been improved: It now writes two more RRD
1542 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1543 * The `cpufreq' plugin now reads another file since the file it did
1544 read so far causes much overhead in the kernel. Also, you need root
1545 to read the old file, but not to read the new one.
1546 * The `hddtemp' plugin can now be configured to connect to another
1547 address and/or port than localhost.
1548 * The `df' plugin now prefers `statvfs' over `statfs'.
1549 * The network code has been rewritten. collectd now supports unicast
1550 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1551 be set in the configfile.
1553 2006-01-24, Version 3.6.2
1554 * Due to a bug in the configfile handling collectd wouldn't start in
1555 client mode. This released fixes this.
1557 2006-01-20, Version 3.6.1
1558 * Due to a bug in `configure.in' all modules and the binary were
1559 linked against `libmysqlclient'. This issue is solved by this
1562 2006-01-17, Version 3.6.0
1563 * A config file has been added. This allows for loading only specific
1565 * A `df' plugin has been added.
1566 * A `mysql' plugin has been added.
1567 * The `ping' plugin doesn't entirely give up hope when a socket error
1568 occurred, but will back of and increase the intervals between tries.
1570 2006-01-21, Version 3.5.2
1571 * Fixed yet another bug in the signal handling.. Stupid typo..
1572 * Improved the ping plugin to not give up on socket errors (backport
1575 2005-12-18, Version 3.5.1
1576 * The PID-file is now deleted correctly when shutting down the daemon.
1577 * SIGINT and SIGTERM are now handled correctly.
1579 2005-12-16, Version 3.5.0 (Revision 326)
1580 * A bug in the `load' module under Solaris has been fixed.
1581 * The `users' module has been contributed by Sebastian Harl. It counts
1582 currently logged in users.
1583 * The CPU module now works under FreeBSD without the use of
1584 `libstatgrab', however SMP support is missing.
1585 * The default directories for the RRD files and the PID file now
1586 depend on the compile time setting of `localstatedir'.
1588 2005-11-15, Version 3.4.0 (Revision 236)
1589 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1590 from gentoo's bugzilla for writing the patch.
1591 * The build dependency for librrd has been removed. Binaries built
1592 without librrd are client-only and will multicast their value as
1593 with the `-c' argument.
1594 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1595 * The newly introduced `-f' switch prevents daemon initialization
1596 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1597 Barcellos for this patch.
1599 2005-11-04, Version 3.3.0 (Revision 216)
1600 * New modules have been added:
1601 - `serial', for monitoring traffic on the serial interfaces
1602 - `nfs', for graphing NFS procedure calls
1603 - `tape', traffic from/to tape devices
1604 * The memory.rrd now accepts more than 4Gig of memory.
1606 2005-10-26, Version 3.2.0 (Revision 200)
1607 * Support for graphing the processes has been added (thanks to Lyonel
1609 * If reading from hddtemp fails collectd will increase the time
1610 between polls up to one day.
1611 * The init.d files have been improved.
1612 * Problems with the spec file have been fixed.
1614 2005-10-16, Version 3.1.0 (Revision 194)
1615 * Added the `setsid' syscall to the startup code.
1616 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1618 2005-09-30, Version 3.0.0 (Revision 184)
1619 * The ability to send/receive data to/from the network (think
1620 multicast) has been added.
1621 * Modules have been split up into shared libraries can be loaded at
1622 runtime. The biggest advantage is that the core program doesn't need
1623 to be linked against an external library.
1624 * A patch by George Kargiotakis has been applied: It fixes the sensors
1625 behaviour then more than one sensor is being queried.
1627 2005-09-16, Version 2.1.0 (Revision 172)
1628 * A module for swap statistics has been added.
1630 2005-09-09, Version 2.0.0 (Revision 135)
1631 * Filenames can no longer be configured at program startup. The only
1632 options as of this version are the directory and ping hosts.
1633 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1634 Soft-IRQ statistics are added to `System'.
1635 * Diskstats now collect read and write bytes, not sectors.
1636 * Ping statistics can now be collected for more than one host. There
1637 is no default any more: If no host is given no host will be pinged.
1638 * A self-written patch for libping has been applied so it builds
1641 2005-09-01, Version 1.8.1 (Revision 123)
1642 * Much improved configure-script: libraries and features may now be
1644 * More detailed warnings/error messages when RRD update fails.
1646 2005-08-29, Version 1.8.0:
1647 * Support for collecting disk statistics under Solaris.
1649 2005-08-25, Version 1.7.0:
1650 * Support for libstatgrab[1] for load, memory usage and network
1651 traffic. CPU- and disk-usage are not (yet) supported, since
1652 libstatgrab returns insufficient information. I will contact the
1654 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1655 aren't necessarily counted linear which is now handled correctly.
1656 [1]: http://www.i-scream.org/libstatgrab/
1658 2005-08-21, Version 1.6.0:
1659 * Basic support for Solaris: System load and cpu-usage can be
1660 collected under Solaris, too. Other stats will follow later.
1661 * Many fixes in the autoconf-script
1662 * Collection/Museum scripts have been added under contrib/museum
1663 * collectd may now be started in unprivileged mode, though ping
1664 statistics will not work.
1666 2005-07-17, Version 1.5.1:
1667 * Diskstats-RRDs now use major/minor for naming. Some systems have
1668 weird strings as disk-names..
1670 2005-07-17, Version 1.5:
1671 * A new module, diskstats, has been added. It collects information
1672 about the disks and partitions.
1674 2005-07-11, Version 1.4.2:
1675 * The meminfo module has been changed to work with more platforms
1676 and/or kernel versions.
1678 2005-07-10, Version 1.4.1: Correct traffic stats
1679 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1680 forgot to correct when I changed that module.
1682 2005-07-09, Version 1.4: More traffic stats
1683 * Traffic is now collected for all interfaces that can be found
1684 * Temperature-statistics are read from lm-sensors if available
1686 2005-07-08, Version 1.3: CPU stats
1687 * Collecting CPU statistics now
1689 2005-07-12, Version 1.2: Using syslog
1690 * collectd is now using the syslog facility to report errors, warnings
1692 * The default directory is now /var/db/collectd
1694 2005-07-10, Version 1.1: Minor changes
1695 * Nothing really useful to say ;)
1697 2005-07-09, Version 1.0: Initial Version
1698 * The following modules are provided:
