505 2009-12-18, Version 4.7.5
506 * Build system, java plugin: Don't use “find -L” to search for Java
507 headers, because it's a GNU extension.
508 * Build system: Support for parallel builds has been improved. Thanks
509 Sebastian Harl and Stefan Völkel for looking into this.
510 * collectd: Print error messages to STDERR if no log plugin has been

582 caused wrong behavior with the persistency option. Thanks to Andrés
583 J. Díaz for fixing these problems.
584 * collectd: Handling of the `Include' configuration option has been
586 * rrdtool plugin: Make sure initialization is run only once. This

698 name which prevented this match to be used as documented. Thanks to
699 Bruno Prémont for finding this problem.
700 * bind plugin: Fix collection of the cached RR sets. The number of RR
701 sets currently in the cache was collected as a counter value, which
702 is nonsense. Thanks to Bruno Prémont for implementing this.
703 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
704 primarily BSDs, don't take it well and crash.
705 * oracle plugin: Portability to 64 bit systems has been improved.
706 * postgresql plugin: The default configuration has been improved.
707 * rrdtool plugin: Fix a possible race condition: If the network plugin

722 user to use `matches' and `targets' to control value processing.
723 * collectd: The new `-T' command line argument allows more in-depth
724 testing of a configuration. Thanks to Doug MacEachern for the patch.
725 * collectd-nagios: The Nagios integration command has been updated to
726 use libcollectdclient. The `percentage' aggregation function has

749 * curl plugin: This new plugin can be used to read web pages and parse
750 them using the same mechanism that's used in the tail plugin.
751 * dbi plugin: This new plugin allows you to connect to a variety of
752 relational databases and use SQL to gather custom statistics from
753 it. It is similar to the already existing PostgreSQL plugin but uses
754 libdbi to communicate with the database(s).
755 * interface plugin: Use the ignorelist framework when selecting /
756 ignoring interfaces. This allows one to use regular expressions to
757 select interfaces, too.

778 updated to be in line with the syntax used by the new dbi and oracle
779 plugins. The compatibility code for the old syntax is present.
780 Support for the new `Result' blocks and the interval parameter has
782 * processes plugin: Stacksize and virtual memory usage statistics have
783 been added. Portability fixes.
784 * rrdcached plugin: This new plugin uses the (still in development)
785 RRD accelerator daemon, rrdcached. This daemon works very similar to
786 the original rrdtool plugin of collectd, but adds some more nice
788 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been

824 2009-01-02, Version 4.5.2
825 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
826 file may be in both locations, especially when the database was
827 installed in a non-standard path. Thanks to Dusty Doris for
829 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
830 Solaris, in the configure script automatically.
831 * build system, tcpconns plugin: Check for `kvm_nlist' and
832 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM

843 * network plugin: Fix the handling of `type' in the network protocol.
844 Due to a programming mistake, only 4 or 8 bytes would be copied to a
845 much larger buffer. This caused the `type' to be transferred much
846 more often than necessary. In some cases, e. g. the `cpu' and
847 `cpufreq' plugins being used at the same time, data may be corrupted
848 in those files. Thanks to Bruno Prémont for debugging and reporting
850 * processes plugin: Fix a possible segmentation fault when specifying
851 invalid configuration options.
852 * unixsock plugin: Make sure the initialization function is run only

856 2008-10-16, Version 4.5.1
857 * build system: Change `--enable-<plugin>' to abort with an error if
858 dependencies are not met. Thanks to Bruno Prémont for the patch.
859 Also, the poisoning of various string functions has been restricted

863 leak in the configuration handling code has been fixed. Thanks to
864 Niraj Tolia for reporting these issues.
865 * collectd: Fix an off-by-one error in the ignorelist functionality.
866 When using regular expressions, the last character would be missing,
867 possibly matching differently from what one would expect.
868 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
870 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
871 Linzberger for reporting the bug.
872 * iptables plugin: Fix an off-by-one error. If a string was just one
873 character too long, it was truncated instead of reporting an error.
874 * network plugin: Fix a memory leak in the configuration handling
875 code. Thanks to Niraj Tolia for reporting this issue.
876 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

990 * collectd: Fixed min/max output in notifications generated by
992 * collectd-nagios: Fix the protocol used to communicate with the
994 * perl plugin: Fail noisily, but don't shutdown the daemon, if
995 initialization has errors. An issue with Perl 5.10 has been fixed.
996 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
997 René Rebe and Siegmund Gorr for reporting this.
999 2008-05-06, Version 4.4.0
1000 * collectd: Internal code cleanups.
1001 * collectd: Added support for a `Flush' command in the unixsock and
1002 exec plugins. This command can be used to force a plugin (or all) to
1003 flush its values to disk.
1004 * collectd: Thresholds can now be configured to apply to one data
1005 source only, making it possible to configure different thresholds
1006 for each data source.
1007 * apache, nginx plugins: Added the possibility to disable host and/or
1009 * ascent plugin: The new ascent plugin reads and parses the statistics
1010 page of an Ascent server.

1016 sensor values via IPMI, the intelligent platform management
1018 * iptables plugin: The iptc library that is used by the iptables
1019 plugin has been added to the distribution, because it is not
1020 provided by all distributions and removed from at least one.
1021 * powerdns plugin: The new powerdns plugin reads statistics from an
1022 authoritative or a recursing PowerDNS name server.
1023 * rrdtool plugin: The size of the files generated with the default
1024 configuration has been decreased.
1025 * tail plugin: The new tail plugin can be used to gather statistics by
1026 continuously reading from log files.
1027 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1028 TeamSpeak2 server and collects statistics about the number of users
1029 and number of channels.
1030 * users plugin: Support for the statgrab library has been added.
1031 * vmem plugin: The new vmem plugin collects very detailed statistics
1032 about the virtual memory subsystem of Linux.
1034 2008-08-30, Version 4.3.4
1035 * Build system: Improved detection of and linking with the statgrab
1037 * collectd: Portability fixes, especially to determine endianess more
1039 * Various plugins: Fix format strings.
1040 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1041 again has been applied.
1042 * memcached plugin: Fix a too short timeout and a related file
1044 * memory plugin: A typo in the libstatgrab code has been fixed.
1045 * network plugin: A fix in the initialization function solves problems
1047 * nginx plugin: A thread-unsafe function has been replaced.
1048 * vserver plugin: A thread-unsafe function has been replaced.
1049 * wireless plugin: A work-around for broken wireless drivers has been
1052 2008-04-22, Version 4.3.3
1053 * build system: Improved detection of several libraries, especially if
1054 they are in non-standard paths.
1055 * build system: Portability fixes: Automatically define "_REENTRANT"
1056 if the libc expects it.
1057 * collectd: Error and warning messages have been improved.
1058 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1060 * apache plugin: Allocate new memory when reading a webpage instead of
1061 using a buffer of static size.
1062 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1064 * hddtemp plugin: Error and warning messages have been improved.
1065 * sensors plugin: Fix sensor collection for some chip types.
1067 2008-03-29, Version 4.3.2
1068 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1069 `Persist' threshold options.
1070 * collectd: Fix handling of missing values in the global value cache.
1071 * collectd: Improved error messages when parsing the configuration.
1072 * sensors plugin: Fix temperature collection with libsensors4.
1073 * unixsock plugin: Fix mixed input and output operation on streams.
1074 * wireless plugin: Fix reading noise value.
1076 2008-03-05, Version 4.3.1
1077 * exec plugin: Set supplementary group IDs.
1079 + Use `memcpy' when constructing/parsing a package to avoid
1080 alignment problems on weird architectures, such as Sparc.
1081 + Translate doubles to/from the x86 byte representation to ensure
1082 cross-platform compatibility.
1083 * ping plugin: Correct the handling of the `TTL' setting.
1084 * swap plugin: Reapply a patch for Solaris.
1085 * tcpconns plugin: Portability improvements.
1087 2008-02-18, Version 4.3.0
1088 * collectd: Notifications have been added to the daemon. Notifications
1089 are status messages that may be associated with a data instance.
1090 * collectd: Threshold checking has been added to the daemon. This
1091 means that you can configure threshold values for each data
1092 instance. If this threshold is exceeded a notification will be
1094 * collectd: The new `FQDNLookup' option tells the daemon to use the
1095 full qualified domain name as the hostname, not just the host part
1096 es returned by `gethostname(2)'.
1097 * collectd: Support for more than one `TypesDB' file has been added.
1098 This is useful when one such file is included in a package but one
1099 wants to add custom type definitions.
1100 * collectd: The `Include' config option has been expanded to handle
1101 entire directories and shell wildcards.
1102 * collectdmon: The new `collectdmon' binary detects when collectd
1103 terminates and automatically restarts it again.
1104 * csv plugin: The CSV plugin is now able to store counter values as a
1105 rate, using the `StoreRates' configuration option.
1106 * exec plugin: Handling of notifications has been added and the
1107 ability to pass arguments to the executed programs has been added.
1108 * hddtemp plugin: The new `TranslateDevicename' option lets you
1109 disable the translation from device names to major-minor-numbers.
1110 * logfile plugin: Handling of notifications has been added.
1111 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1112 domain name lookups in this plugin.
1113 * perl plugin: Many internal changes added support for handling multiple
1114 threads making the plugin reasonably usable inside collectd. The API has
1115 been extended to support notifications and export global variables to
1116 Perl plugins; callbacks now have to be identified by name rather than a
1117 pointer to a subroutine. The plugin is no longer experimental.
1118 * uuid plugin: The new UUID plugin sets the hostname to an unique
1119 identifier for this host. This is meant for setups where each client
1120 may migrate to another physical host, possibly going through one or
1121 more name changes in the process. Thanks to Richard Jones from
1122 Red Hat's Emerging Technology group for this plugin.
1123 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1124 CPU, disk and network statistics about guest systems on the same
1125 physical server. Thanks to Richard Jones from Red Hat's Emerging
1126 Technology group for this plugin.
1128 2008-04-22, Version 4.2.7
1129 * build system: Improved detection of several libraries, especially if
1130 they are in non-standard paths.
1131 * build system: Portability fixes: Automatically define "_REENTRANT"
1132 if the libc expects it.
1133 * collectd: Error and warning messages have been improved.
1134 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1136 * apache plugin: Allocate new memory when reading a webpage instead of
1137 using a buffer of static size.
1138 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1140 * hddtemp plugin: Error and warning messages have been improved.
1141 * sensors plugin: Fix sensor collection for some chip types.
1143 2008-03-29, Version 4.2.6
1144 * collectd: Improved error messages when parsing the configuration.
1145 * sensors plugin: Fix temperature collection with libsensors4.
1146 * unixsock plugin: Fix mixed input and output operation on streams.
1147 * wireless plugin: Fix reading noise value.
1149 2008-03-04, Version 4.2.5
1150 * apache plugin: Improved initialization and error messages.
1151 * exec plugin: Set supplementary group IDs.
1153 + Create separate threads for reading from the socket and parsing
1154 and dispatching incoming packets. Versions prior to this may have
1155 problems in high-load situations, where the socket receive buffers
1156 overflows, resulting in gaps in the data.
1157 + Use `memcpy' when constructing/parsing a package to avoid
1158 alignment problems on weird architectures, such as Sparc.
1159 + Translate doubles to/from the x86 byte representation to ensure
1160 cross-platform compatibility.
1161 * ping plugin: Correct the handling of the `TTL' setting.
1162 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1163 * swap plugin: Reapply a patch for Solaris.
1164 * tcpconns plugin: Portability improvements.
1166 2008-01-21, Version 4.2.4
1167 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1168 the permission on the socket as documented in the manpage. Thanks to
1169 Evgeny Chukreev for fixing this issue.
1170 * collectd: The documentation has been improved.
1172 2007-12-28, Version 4.2.3
1173 * sensors plugin: Updated the plugin to build and work with version 3
1174 of the libsensors library.
1176 2007-12-15, Version 4.2.2
1177 * nginx plugin: Incorrect comparison of strings lead to a segfault
1178 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1180 * logfile plugin: The config option `Timestamp' was handled
1181 incorrectly and basically always active. Thanks to Luke Heberling
1184 2007-11-08, Version 4.2.1
1185 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1186 enabled on the host.
1187 * snmp plugin: Fix a memory leak.
1189 2007-10-27, Version 4.2.0
1190 * collectd: The new config option `Include' lets you include other
1191 configfiles and thus split up your config into smaller parts. This
1192 may be especially interesting for the snmp plugin to keep the data
1193 definitions separate from the host definitions.
1194 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1195 (number of connections, octets and packets for each service and
1196 destination). Thanks to Sebastian Harl for this plugin.
1197 * memcached plugin: The new `memcached' plugin connects to a memcached
1198 daemon process and collects statistics of this distributed caching
1199 system. Thanks to Antony Dovgal for contributing this plugin.
1200 * nginx plugin: The new `nginx' plugin reads the status page of an
1201 nginx daemon and saves the handled connections and requests.
1202 * perl plugin: Many changes, including the added `EnableDebugger'
1203 config option which lets you debug your Perl plugins more easily.
1204 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1205 be more thread-safe otherwise by locking calls to the library.
1206 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1207 correct the values returned by SNMP-agents. If a <data> block is
1208 defined as `table' the instance is now optional. The sequence number
1209 is used as the type-instance in this case. The new `InstancePrefix'
1210 option allows to add arbitrary prefixes to the type-instance.
1211 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1212 certain TCP connections and what state they're in. This can be used
1213 to see how many connections your FTP server has to handle or how
1214 many outgoing connections your mailserver has open.
1216 2008-01-11, Version 4.1.6
1217 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1218 the permission on the socket as documented in the manpage. Thanks to
1219 Evgeny Chukreev for fixing this issue.

1222 2007-12-27, Version 4.1.5
1223 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1225 * sensors plugin: Updated the plugin to build and work with version 3
1226 of the libsensors library.
1228 2007-11-08, Version 4.1.4
1229 * Build system: Improve detection of the rrd library, especially if
1230 it's in a non-standard location.
1231 * Build system: A bug when parsing the argument for
1232 `--with-libnetsnmp' has been fixed.
1233 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1234 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1235 a deadlock or delay when shutting down the daemon.
1236 * snmp plugin: Fix a memory leak.
1238 2007-10-24, Version 4.1.3
1239 * collectd: A build issue under Solaris has been resolved by renaming
1241 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1242 be more thread-safe otherwise by locking calls to the library.
1244 2007-09-28, Version 4.1.2
1245 * apcups plugin: Fix reporting of the `load percent' data.
1246 * wireless plugin: Correct the handling of cards returning signal and
1247 noise quality as percentage.
1248 * perl plugin: Fix a possible buffer overflow in get_module_name().
1249 * build system: Further improve the detection of libraries.
1250 * netlink plugin: Build issues under some older versions of the Linux
1251 includes (i. e. Debian Sarge) have been fixed.
1252 * snmp plugin: Fix a potential segfault when a host times out. Add
1253 support for the `timeticks' type.
1255 2007-09-12, Version 4.1.1
1256 * Build system: The detection of `libnetlink' has been improved.
1257 * collectd: The documentation has been fixed in numerous places.
1258 * exec plugin: Setting the group under which to run a program has been
1260 * collectd: The `sstrerror' function was improved to work correctly
1261 with the broken GNU version of `strerror_r'.
1262 * collectd: Write an error message to STDERR when loading of a plugin
1264 * apcups plugin: Fix the `types' used to submit the values: They still
1265 has an `apcups_' prefix which doesn't work anymore.
1266 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1267 whatever the client thinks is `now'..
1269 2007-09-01, Version 4.1.0
1270 * Build system: The build system has been changed to automatically
1271 disable all plugins, which are missing dependencies. The dependency
1272 checking has been removed from the plugins themselves to remove
1274 * Flexible interval: The interval of collected data is now sent along
1275 with the data itself over the network, so that the interval-settings
1276 of server and clients no longer needs to match.
1277 * netlink plugin: The new `netlink' plugin connects to the Linux
1278 kernel using a netlink socket and uses it to query information about
1279 interfaces, qdiscs and classes.
1280 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1281 to not block data collection.
1282 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1283 network devices, such as switches, routers, thermometers, rack
1284 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1286 * unixsock plugin: Added the `LISTVAL' command.
1287 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1288 of music played with xmms.
1290 2007-09-28, Version 4.0.9
1291 * apcups plugin: Fix reporting of the `load percent' data.
1292 * wireless plugin: Correct the handling of cards returning signal and
1293 noise quality as percentage.
1294 * perl plugin: Fix a possible buffer overflow in get_module_name().
1296 2007-09-12, Version 4.0.8
1297 * collectd: The `sstrerror' function was improved to work correctly
1298 with the broken GNU version of `strerror_r'.
1299 * collectd: Write an error message to STDERR when loading of a plugin
1301 * apcups plugin: Fix the `types' used to submit the values: They still
1302 has an `apcups_' prefix which doesn't work anymore.
1303 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1304 whatever the client thinks is `now'..
1306 2007-08-26, Version 4.0.7
1307 * documentation: Some typos have been fixed and some information has
1309 * build system: Many fixes for detecting libraries in unusual places,
1310 such as on RedHat systems. The affected libraries are `libcurl',
1311 `libmysql', and `libupsclient'.
1312 * network plugin: Allow the `Port' option to be specified as a number
1313 (i. e. without quotes).
1314 * nut plugin: A fix allows linking the nut plugin against
1315 libupsclient, version >= 2.2.0.
1316 * processes plugin: Fix a potential segmentation fault.
1318 2007-07-30, Version 4.0.6
1319 * sensors plugin: Fix the ignorelist functionality: Only the `type
1320 instance' was used to match against the list, but the documentation
1321 told otherwise. This release fixes the code, so it complies with the
1323 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1324 configuration messages will end up in the logging facility.
1325 * conrtib/fedora: The contributed specfile for Fedora has been
1328 2007-07-05, Version 4.0.5
1329 * Portability: More fixes for OpenBSD have been included.
1331 2007-06-24, Version 4.0.4
1332 * cpu plugin: Fixed the Solaris code.

1334 * interface plugin: Fixed the Solaris code.
1335 * load plugin: Fixed the alternative `/proc' Linux code.
1336 * memory plugin: Fixed the Solaris code.
1337 * oconfig: Don't require `-lfl' anymore.
1339 2007-06-19, Version 4.0.3
1340 * cpu plugin: Fix the Darwin / Mac OS X code.
1341 * ping plugin: Use the return value of `getpid', not its address.
1342 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1343 initialized correctly.
1344 * configure: Added `--with-nan-emulation' to aid cross compilation.
1346 2007-06-12, Version 4.0.2
1347 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1348 they're given in numerically form.
1350 2007-06-07, Version 4.0.1
1351 * iptables plugin: A bug in the configuration routine has been fixed.
1352 Setting a comment in the configfile will no longer cause a
1355 2007-06-03, Version 4.0.0
1356 * collectd: The plugin-infrastructure has been changed to allow for
1357 more types of plugins, namely `write' and `log' plugins.
1358 * collectd: The read-function has been changed to read many plugins in
1359 parallel, using threads. Thus, plugins generally need to use
1360 thread-safe functions from now on.
1361 * collectd: The '-t' command line options allows to perform syntax tests
1362 of the configuration file and exit immediately.
1363 * csv plugin: The new `csv' plugin handles output to `comma separated
1365 * rrdtool plugin: The new `rrdtool' plugin handles output to
1366 RRD-files. Data can be cached to combine multiple updates into one
1367 write to increase IO-performance.
1368 * network plugin: The new `network' plugin handles IO via the network.
1369 It implements a different, much more extensible protocol which can
1370 combine many values in one packet, decreasing the number of UDP-
1371 packets being sent. It can read from and send to the network and
1372 with the appropriate configuration even forward packets to other
1374 * unixsock plugin: The new `unixsock' plugin provides an interface to
1375 communicate with the daemon while it is running. Right now the
1376 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1378 * perl plugin: The new `perl' plugin allows you to write extensions
1379 for collectd in the scripting-language Perl.
1380 * logfile plugin: The new `logfile' plugin writes logmessages to files
1381 or STDOUT or STDERR.
1382 * syslog plugin: The new `syslog' plugin sends logmessages to the
1383 system's syslog daemon.
1384 * entropy plugin: The new `entropy' plugin collects the amount of
1385 entropy currently being available to the system.
1386 * exec plugin: The new `exec' plugin forks child processes and reads
1387 back values provided by the forked processes.
1388 * iptables plugin: The new `iptables' plugin reads counters from
1389 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1391 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1392 to Peter Holik for contributing this plugin.
1393 * nut plugin: The new `nut' plugin connects the upsd of the `network
1394 ups tools' and reads information about the connected UPS.
1395 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1396 connections) field was added by Florent Monbillard.
1397 * collectd-nagios: The new `collectd-nagios' binary queries values
1398 from collectd, parses them and exits according to Nagios-standards.
1399 * manpages: The manpages have been improved a lot.
1401 2007-09-28, Version 3.11.7
1402 * wireless plugin: Correct the handling of cards returning signal and
1403 noise quality as percentage.
1405 2007-08-31, Version 3.11.6
1406 * processes plugin: Fix a potential segmentation fault.
1408 2007-05-29, Version 3.11.5
1409 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1410 * ntpd plugin: Fix a potential buffer overflow.
1411 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1412 were accounted as `zombies'.
1414 2007-04-10, Version 3.11.4
1415 * dns plugin: Change the order of includes to make the plugin compile
1418 2007-03-30, Version 3.11.3
1419 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1420 of the unused `COLLECT_KSTAT'.
1422 2007-02-11, Version 3.11.2
1423 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1424 NULL-pointer may have been passed to `printf' which causes a
1425 segfault with some libcs.
1427 2007-02-10, Version 3.11.1
1428 * df plugin: Some wrong defines have been fixed so the plugin works
1429 under Solaris again.
1430 * dns plugin: The usage of a struct has been fixed to work with
1432 * processes plugin: Some missing defines have been added so the plugin
1433 compiles cleanly under FreeBSD and presumably other UNIXes.
1435 2006-12-22, Version 3.11.0
1436 * collectd: The new command line option `-P' makes it easier for
1437 distributors to change the location of PID-files.
1438 * collectd: The daemon shuts down faster now which makes it easier to
1439 write init.d-scripts for it.
1440 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1441 caused problems every now and then.
1442 * df plugin: New config options allow to ignore certain mountpoints,
1443 filesystem types or devices.
1444 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1445 and interprets it. It collects traffic as well as qtype, opcode and
1447 * email plugin: Sebastian Harl has contributed this plugin which
1448 counts received mails in categories (e. g. ham, spam, virus), spam
1449 score (as given by SpamAssassin) and check types.
1450 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1451 uses `mbmon' to gather information from sensors on the motherboard.
1452 * processes plugin: Collect detailed statistics for configured
1453 processes, that's process and thread count, CPU usage, resident
1454 segment size and pagefaults.
1455 * multimeter plugin: Peter Holik contributed a new plugin which
1456 queries multimeters.
1457 * sensors plugin: Lubos Stanek has put much effort into improving this
1458 plugin, including `extended naming', collection of voltage values
1459 and the possibility to ignore certain values.
1461 2006-12-21, Version 3.10.4
1462 * Max Kellermann has identified a bug in the server routine: When
1463 opening a socket fails the daemon will (re)try opening the socket in
1464 an endless loop, ultimately leading to a `EMFILE' error.
1466 2006-11-04, Version 3.10.3
1467 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1468 ntpd's reply was sent in more than one packet, the buffer size was
1469 calculated incorrectly, resulting in the reading of uninitialized or
1472 2006-11-01, Version 3.10.2
1473 * The sample config file has been improved.
1474 * Errors in the manpages have been corrected.
1475 * The ping-plugin now adds hosts during initialization, not during
1476 startup. This speeds up startup when no network connectivity is
1477 available. Also, the hosts are being added later when the network is
1479 * Improved BSD-support for the df-plugin.
1480 * Fixed syntax errors in the swap-plugin for Mac OS X.
1481 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1483 * Don't disable the mysql-plugin if connecting to the database fails
1484 during initialization. Instead, try again in increasing intervals.
1486 2006-07-19, Version 3.10.1
1487 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1488 the apcups cannot be reached, unconnected sockets will pile up and
1489 eventually lead to `Too many open files' errors.
1491 2006-07-09, Version 3.10.0
1492 * The `disk' plugin has been ported to Darwin.
1493 * The `battery' plugin should work on many Apple computers now.
1494 * The `traffic' plugin can now ignore certain interfaces. Also,
1495 statistics for sent/received packets and errors have been added.

1497 to Anthony Gialluca for contributing this plugin and providing me
1498 with a test environment :)
1499 * A plugin for monitoring an NTP instance and the local clock drift
1502 2006-06-25, Version 3.9.4
1503 * The Solaris code in the `swap' plugin has been changed to reflect
1504 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1506 * The debugging system has been fixed to work with the Sun libc.
1507 * When built without librrd the variable `operating_mode' could be
1508 uninitialized. Thanks to David Elliot for reporting the bug.
1510 2006-06-01, Version 3.9.3
1511 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1512 operating systems also profit from the changes, but I wasn't able to
1514 * Changed the build system to find the netinet-includes under FreeBSD
1515 and therefore successfully build the `liboping' library there.
1517 2006-05-09, Version 3.9.2
1518 * Applied a patch to the `liboping' library. Due to a bug in the
1519 sequence checking the `ping' plugin stopped working after
1520 approximately 7.6 days.
1522 2006-05-09, Version 3.8.5
1523 * Applied a patch to the `liboping' library. Due to a bug in the
1524 sequence checking the `ping' plugin stopped working after
1525 approximately 7.6 days.
1527 2006-04-21, Version 3.9.1
1528 * Build issues with Solaris and possible other architectures have been
1530 * Problems when building the `apache'-plugin without `libcurl' have
1532 * A bug in the `ping' plugin has been fixed. Sorry folks.
1534 2006-04-02, Version 3.9.0
1535 * A plugin to monitor the Apache webserver has been added.
1536 <http://httpd.apache.org/>
1537 * A plugin to collect statistics about virtual servers using VServer.
1538 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1540 * A plugin for wireless LAN cards has been added. It monitors signal
1541 strength, link quality and noise ratio..
1542 * A plugin for Apple hardware sensors has been added.
1543 * An option to compile collectd with different `step' and `heartbeat'
1544 settings has been added. The size of RRAs is no longer static but
1545 calculated based on the settings for `step' and `width'.
1546 * The `ping' plugin can now be configured to use a certain TTL.
1547 * A plugin to monitor the hardware sensors of Apple computers has been
1549 * The plugins `cpu', `memory', `processes' and `traffic' have been
1550 ported to Mach/Darwin (Mac OS X).
1551 * The `log mode' has been contributed by Christophe Kalt. It writes
1552 the data into text files rather than RRD files.
1554 2006-04-09, Version 3.8.4
1555 * Applied patch by Vincent Stehlé which improves the disk-name
1556 resolution in the `hddtemp' plugin for Linux systems.
1558 2006-04-02, Version 3.8.3
1559 * Applied a patch by James Byers: The MySQL plugin was not working
1560 with MySQL 5.0.2 or later.
1562 2006-03-14, Version 3.8.2
1563 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1564 the GNU libc, because it points to `/etc/fstab' rather than
1567 2006-03-13, Version 3.8.1
1568 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1569 * Fixes in the debian `postinst' and `init.d' scripts.
1571 2006-03-09, Version 3.8.0
1572 * The `ping' plugin no longer uses `libping' but a self written
1573 library named `liboping'. With this library it's possible to ping
1574 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1576 2006-02-18, Version 3.7.2
1577 * A simple bug in the `battery' plugin has been fixed. It should now
1578 work with ACPI based batteries as well. Thanks to Sebastian for
1580 * Fixing a bug that prevented collectd to be built without librrd.
1581 Thanks to Werner Heuser for reporting it.
1583 2006-02-04, Version 3.7.1
1584 * The new network code has been improved to build with older versions

1587 to Tommie Gannert for this patch.
1589 2006-01-30, Version 3.7.0
1590 * The `battery' plugin has been added. It collects information about
1592 * The MySQL plugin has been improved: It now writes two more RRD
1593 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1594 * The `cpufreq' plugin now reads another file since the file it did
1595 read so far causes much overhead in the kernel. Also, you need root
1596 to read the old file, but not to read the new one.
1597 * The `hddtemp' plugin can now be configured to connect to another
1598 address and/or port than localhost.
1599 * The `df' plugin now prefers `statvfs' over `statfs'.
1600 * The network code has been rewritten. collectd now supports unicast
1601 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1602 be set in the configfile.
1604 2006-01-24, Version 3.6.2
1605 * Due to a bug in the configfile handling collectd wouldn't start in
1606 client mode. This released fixes this.
1608 2006-01-20, Version 3.6.1
1609 * Due to a bug in `configure.in' all modules and the binary were
1610 linked against `libmysqlclient'. This issue is solved by this
1613 2006-01-17, Version 3.6.0
1614 * A config file has been added. This allows for loading only specific
1616 * A `df' plugin has been added.
1617 * A `mysql' plugin has been added.
1618 * The `ping' plugin doesn't entirely give up hope when a socket error
1619 occurred, but will back of and increase the intervals between tries.
1621 2006-01-21, Version 3.5.2
1622 * Fixed yet another bug in the signal handling.. Stupid typo..
1623 * Improved the ping plugin to not give up on socket errors (backport
1626 2005-12-18, Version 3.5.1
1627 * The PID-file is now deleted correctly when shutting down the daemon.
1628 * SIGINT and SIGTERM are now handled correctly.
1630 2005-12-16, Version 3.5.0 (Revision 326)
1631 * A bug in the `load' module under Solaris has been fixed.
1632 * The `users' module has been contributed by Sebastian Harl. It counts
1633 currently logged in users.
1634 * The CPU module now works under FreeBSD without the use of
1635 `libstatgrab', however SMP support is missing.
1636 * The default directories for the RRD files and the PID file now
1637 depend on the compile time setting of `localstatedir'.
1639 2005-11-15, Version 3.4.0 (Revision 236)
1640 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1641 from gentoo's bugzilla for writing the patch.
1642 * The build dependency for librrd has been removed. Binaries built
1643 without librrd are client-only and will multicast their value as
1644 with the `-c' argument.
1645 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1646 * The newly introduced `-f' switch prevents daemon initialization
1647 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1648 Barcellos for this patch.
1650 2005-11-04, Version 3.3.0 (Revision 216)
1651 * New modules have been added:
1652 - `serial', for monitoring traffic on the serial interfaces
1653 - `nfs', for graphing NFS procedure calls
1654 - `tape', traffic from/to tape devices
1655 * The memory.rrd now accepts more than 4Gig of memory.
1657 2005-10-26, Version 3.2.0 (Revision 200)
1658 * Support for graphing the processes has been added (thanks to Lyonel
1660 * If reading from hddtemp fails collectd will increase the time
1661 between polls up to one day.
1662 * The init.d files have been improved.
1663 * Problems with the spec file have been fixed.
1665 2005-10-16, Version 3.1.0 (Revision 194)
1666 * Added the `setsid' syscall to the startup code.
1667 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1669 2005-09-30, Version 3.0.0 (Revision 184)
1670 * The ability to send/receive data to/from the network (think
1671 multicast) has been added.
1672 * Modules have been split up into shared libraries can be loaded at
1673 runtime. The biggest advantage is that the core program doesn't need
1674 to be linked against an external library.
1675 * A patch by George Kargiotakis has been applied: It fixes the sensors
1676 behaviour then more than one sensor is being queried.
1678 2005-09-16, Version 2.1.0 (Revision 172)
1679 * A module for swap statistics has been added.
1681 2005-09-09, Version 2.0.0 (Revision 135)
1682 * Filenames can no longer be configured at program startup. The only
1683 options as of this version are the directory and ping hosts.
1684 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1685 Soft-IRQ statistics are added to `System'.
1686 * Diskstats now collect read and write bytes, not sectors.
1687 * Ping statistics can now be collected for more than one host. There
1688 is no default any more: If no host is given no host will be pinged.
1689 * A self-written patch for libping has been applied so it builds
1692 2005-09-01, Version 1.8.1 (Revision 123)
1693 * Much improved configure-script: libraries and features may now be
1695 * More detailed warnings/error messages when RRD update fails.
1697 2005-08-29, Version 1.8.0:
1698 * Support for collecting disk statistics under Solaris.
1700 2005-08-25, Version 1.7.0:
1701 * Support for libstatgrab[1] for load, memory usage and network
1702 traffic. CPU- and disk-usage are not (yet) supported, since
1703 libstatgrab returns insufficient information. I will contact the
1705 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1706 aren't necessarily counted linear which is now handled correctly.
1707 [1]: http://www.i-scream.org/libstatgrab/
1709 2005-08-21, Version 1.6.0:
1710 * Basic support for Solaris: System load and cpu-usage can be
1711 collected under Solaris, too. Other stats will follow later.
1712 * Many fixes in the autoconf-script
1713 * Collection/Museum scripts have been added under contrib/museum
1714 * collectd may now be started in unprivileged mode, though ping
1715 statistics will not work.
1717 2005-07-17, Version 1.5.1:
1718 * Diskstats-RRDs now use major/minor for naming. Some systems have
1719 weird strings as disk-names..
1721 2005-07-17, Version 1.5:
1722 * A new module, diskstats, has been added. It collects information
1723 about the disks and partitions.
1725 2005-07-11, Version 1.4.2:
1726 * The meminfo module has been changed to work with more platforms
1727 and/or kernel versions.
1729 2005-07-10, Version 1.4.1: Correct traffic stats
1730 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1731 forgot to correct when I changed that module.
1733 2005-07-09, Version 1.4: More traffic stats
1734 * Traffic is now collected for all interfaces that can be found
1735 * Temperature-statistics are read from lm-sensors if available
1737 2005-07-08, Version 1.3: CPU stats
1738 * Collecting CPU statistics now
1740 2005-07-12, Version 1.2: Using syslog
1741 * collectd is now using the syslog facility to report errors, warnings
1743 * The default directory is now /var/db/collectd
1745 2005-07-10, Version 1.1: Minor changes
1746 * Nothing really useful to say ;)
1748 2005-07-09, Version 1.0: Initial Version
1749 * The following modules are provided:
projects / collectd.git / blob
