637 name which prevented this match to be used as documented. Thanks to
638 Bruno Prémont for finding this problem.
639 * bind plugin: Fix collection of the cached RR sets. The number of RR
640 sets currently in the cache was collected as a counter value, which
641 is nonsense. Thanks to Bruno Prémont for implementing this.
642 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
643 primarily BSDs, don't take it well and crash.
644 * oracle plugin: Portability to 64 bit systems has been improved.
645 * postgresql plugin: The default configuration has been improved.
646 * rrdtool plugin: Fix a possible race condition: If the network plugin

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

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

769 Solaris, in the configure script automatically.
770 * build system, tcpconns plugin: Check for `kvm_nlist' and
771 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM

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

795 2008-10-16, Version 4.5.1
796 * build system: Change `--enable-<plugin>' to abort with an error if
797 dependencies are not met. Thanks to Bruno Prémont for the patch.
798 Also, the poisoning of various string functions has been restricted

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

991 2008-04-22, Version 4.3.3
992 * build system: Improved detection of several libraries, especially if
993 they are in non-standard paths.
994 * build system: Portability fixes: Automatically define "_REENTRANT"
995 if the libc expects it.
996 * collectd: Error and warning messages have been improved.
997 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
999 * apache plugin: Allocate new memory when reading a webpage instead of
1000 using a buffer of static size.
1001 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1003 * hddtemp plugin: Error and warning messages have been improved.
1004 * sensors plugin: Fix sensor collection for some chip types.
1006 2008-03-29, Version 4.3.2
1007 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1008 `Persist' threshold options.
1009 * collectd: Fix handling of missing values in the global value cache.
1010 * collectd: Improved error messages when parsing the configuration.
1011 * sensors plugin: Fix temperature collection with libsensors4.
1012 * unixsock plugin: Fix mixed input and output operation on streams.
1013 * wireless plugin: Fix reading noise value.
1015 2008-03-05, Version 4.3.1
1016 * exec plugin: Set supplementary group IDs.
1018 + Use `memcpy' when constructing/parsing a package to avoid
1019 alignment problems on weird architectures, such as Sparc.
1020 + Translate doubles to/from the x86 byte representation to ensure
1021 cross-platform compatibility.
1022 * ping plugin: Correct the handling of the `TTL' setting.
1023 * swap plugin: Reapply a patch for Solaris.
1024 * tcpconns plugin: Portability improvements.
1026 2008-02-18, Version 4.3.0
1027 * collectd: Notifications have been added to the daemon. Notifications
1028 are status messages that may be associated with a data instance.
1029 * collectd: Threshold checking has been added to the daemon. This
1030 means that you can configure threshold values for each data
1031 instance. If this threshold is exceeded a notification will be
1033 * collectd: The new `FQDNLookup' option tells the daemon to use the
1034 full qualified domain name as the hostname, not just the host part
1035 es returned by `gethostname(2)'.
1036 * collectd: Support for more than one `TypesDB' file has been added.
1037 This is useful when one such file is included in a package but one
1038 wants to add custom type definitions.
1039 * collectd: The `Include' config option has been expanded to handle
1040 entire directories and shell wildcards.
1041 * collectdmon: The new `collectdmon' binary detects when collectd
1042 terminates and automatically restarts it again.
1043 * csv plugin: The CSV plugin is now able to store counter values as a
1044 rate, using the `StoreRates' configuration option.
1045 * exec plugin: Handling of notifications has been added and the
1046 ability to pass arguments to the executed programs has been added.
1047 * hddtemp plugin: The new `TranslateDevicename' option lets you
1048 disable the translation from device names to major-minor-numbers.
1049 * logfile plugin: Handling of notifications has been added.
1050 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1051 domain name lookups in this plugin.
1052 * perl plugin: Many internal changes added support for handling multiple
1053 threads making the plugin reasonably usable inside collectd. The API has
1054 been extended to support notifications and export global variables to
1055 Perl plugins; callbacks now have to be identified by name rather than a
1056 pointer to a subroutine. The plugin is no longer experimental.
1057 * uuid plugin: The new UUID plugin sets the hostname to an unique
1058 identifier for this host. This is meant for setups where each client
1059 may migrate to another physical host, possibly going through one or
1060 more name changes in the process. Thanks to Richard Jones from
1061 Red Hat's Emerging Technology group for this plugin.
1062 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1063 CPU, disk and network statistics about guest systems on the same
1064 physical server. Thanks to Richard Jones from Red Hat's Emerging
1065 Technology group for this plugin.
1067 2008-04-22, Version 4.2.7
1068 * build system: Improved detection of several libraries, especially if
1069 they are in non-standard paths.
1070 * build system: Portability fixes: Automatically define "_REENTRANT"
1071 if the libc expects it.
1072 * collectd: Error and warning messages have been improved.
1073 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1075 * apache plugin: Allocate new memory when reading a webpage instead of
1076 using a buffer of static size.
1077 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1079 * hddtemp plugin: Error and warning messages have been improved.
1080 * sensors plugin: Fix sensor collection for some chip types.
1082 2008-03-29, Version 4.2.6
1083 * collectd: Improved error messages when parsing the configuration.
1084 * sensors plugin: Fix temperature collection with libsensors4.
1085 * unixsock plugin: Fix mixed input and output operation on streams.
1086 * wireless plugin: Fix reading noise value.
1088 2008-03-04, Version 4.2.5
1089 * apache plugin: Improved initialization and error messages.
1090 * exec plugin: Set supplementary group IDs.
1092 + Create separate threads for reading from the socket and parsing
1093 and dispatching incoming packets. Versions prior to this may have
1094 problems in high-load situations, where the socket receive buffers
1095 overflows, resulting in gaps in the data.
1096 + Use `memcpy' when constructing/parsing a package to avoid
1097 alignment problems on weird architectures, such as Sparc.
1098 + Translate doubles to/from the x86 byte representation to ensure
1099 cross-platform compatibility.
1100 * ping plugin: Correct the handling of the `TTL' setting.
1101 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1102 * swap plugin: Reapply a patch for Solaris.
1103 * tcpconns plugin: Portability improvements.
1105 2008-01-21, Version 4.2.4
1106 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1107 the permission on the socket as documented in the manpage. Thanks to
1108 Evgeny Chukreev for fixing this issue.
1109 * collectd: The documentation has been improved.
1111 2007-12-28, Version 4.2.3
1112 * sensors plugin: Updated the plugin to build and work with version 3
1113 of the libsensors library.
1115 2007-12-15, Version 4.2.2
1116 * nginx plugin: Incorrect comparison of strings lead to a segfault
1117 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1119 * logfile plugin: The config option `Timestamp' was handled
1120 incorrectly and basically always active. Thanks to Luke Heberling
1123 2007-11-08, Version 4.2.1
1124 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1125 enabled on the host.
1126 * snmp plugin: Fix a memory leak.
1128 2007-10-27, Version 4.2.0
1129 * collectd: The new config option `Include' lets you include other
1130 configfiles and thus split up your config into smaller parts. This
1131 may be especially interesting for the snmp plugin to keep the data
1132 definitions separate from the host definitions.
1133 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1134 (number of connections, octets and packets for each service and
1135 destination). Thanks to Sebastian Harl for this plugin.
1136 * memcached plugin: The new `memcached' plugin connects to a memcached
1137 daemon process and collects statistics of this distributed caching
1138 system. Thanks to Antony Dovgal for contributing this plugin.
1139 * nginx plugin: The new `nginx' plugin reads the status page of an
1140 nginx daemon and saves the handled connections and requests.
1141 * perl plugin: Many changes, including the added `EnableDebugger'
1142 config option which lets you debug your Perl plugins more easily.
1143 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1144 be more thread-safe otherwise by locking calls to the library.
1145 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1146 correct the values returned by SNMP-agents. If a <data> block is
1147 defined as `table' the instance is now optional. The sequence number
1148 is used as the type-instance in this case. The new `InstancePrefix'
1149 option allows to add arbitrary prefixes to the type-instance.
1150 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1151 certain TCP connections and what state they're in. This can be used
1152 to see how many connections your FTP server has to handle or how
1153 many outgoing connections your mailserver has open.
1155 2008-01-11, Version 4.1.6
1156 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1157 the permission on the socket as documented in the manpage. Thanks to
1158 Evgeny Chukreev for fixing this issue.
1159 * collectd: The documentation has been improved.
1161 2007-12-27, Version 4.1.5
1162 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1164 * sensors plugin: Updated the plugin to build and work with version 3
1165 of the libsensors library.
1167 2007-11-08, Version 4.1.4
1168 * Build system: Improve detection of the rrd library, especially if
1169 it's in a non-standard location.
1170 * Build system: A bug when parsing the argument for
1171 `--with-libnetsnmp' has been fixed.
1172 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1173 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1174 a deadlock or delay when shutting down the daemon.
1175 * snmp plugin: Fix a memory leak.
1177 2007-10-24, Version 4.1.3
1178 * collectd: A build issue under Solaris has been resolved by renaming
1180 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1181 be more thread-safe otherwise by locking calls to the library.
1183 2007-09-28, Version 4.1.2
1184 * apcups plugin: Fix reporting of the `load percent' data.
1185 * wireless plugin: Correct the handling of cards returning signal and
1186 noise quality as percentage.
1187 * perl plugin: Fix a possible buffer overflow in get_module_name().
1188 * build system: Further improve the detection of libraries.
1189 * netlink plugin: Build issues under some older versions of the Linux
1190 includes (i. e. Debian Sarge) have been fixed.
1191 * snmp plugin: Fix a potential segfault when a host times out. Add
1192 support for the `timeticks' type.
1194 2007-09-12, Version 4.1.1
1195 * Build system: The detection of `libnetlink' has been improved.
1196 * collectd: The documentation has been fixed in numerous places.
1197 * exec plugin: Setting the group under which to run a program has been
1199 * collectd: The `sstrerror' function was improved to work correctly
1200 with the broken GNU version of `strerror_r'.
1201 * collectd: Write an error message to STDERR when loading of a plugin
1203 * apcups plugin: Fix the `types' used to submit the values: They still
1204 has an `apcups_' prefix which doesn't work anymore.
1205 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1206 whatever the client thinks is `now'..
1208 2007-09-01, Version 4.1.0
1209 * Build system: The build system has been changed to automatically
1210 disable all plugins, which are missing dependencies. The dependency
1211 checking has been removed from the plugins themselves to remove
1213 * Flexible interval: The interval of collected data is now sent along
1214 with the data itself over the network, so that the interval-settings
1215 of server and clients no longer needs to match.
1216 * netlink plugin: The new `netlink' plugin connects to the Linux
1217 kernel using a netlink socket and uses it to query information about
1218 interfaces, qdiscs and classes.
1219 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1220 to not block data collection.
1221 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1222 network devices, such as switches, routers, thermometers, rack
1223 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1225 * unixsock plugin: Added the `LISTVAL' command.
1226 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1227 of music played with xmms.
1229 2007-09-28, Version 4.0.9
1230 * apcups plugin: Fix reporting of the `load percent' data.
1231 * wireless plugin: Correct the handling of cards returning signal and
1232 noise quality as percentage.
1233 * perl plugin: Fix a possible buffer overflow in get_module_name().
1235 2007-09-12, Version 4.0.8
1236 * collectd: The `sstrerror' function was improved to work correctly
1237 with the broken GNU version of `strerror_r'.
1238 * collectd: Write an error message to STDERR when loading of a plugin
1240 * apcups plugin: Fix the `types' used to submit the values: They still
1241 has an `apcups_' prefix which doesn't work anymore.
1242 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1243 whatever the client thinks is `now'..
1245 2007-08-26, Version 4.0.7
1246 * documentation: Some typos have been fixed and some information has
1248 * build system: Many fixes for detecting libraries in unusual places,
1249 such as on RedHat systems. The affected libraries are `libcurl',
1250 `libmysql', and `libupsclient'.
1251 * network plugin: Allow the `Port' option to be specified as a number
1252 (i. e. without quotes).
1253 * nut plugin: A fix allows linking the nut plugin against
1254 libupsclient, version >= 2.2.0.
1255 * processes plugin: Fix a potential segmentation fault.
1257 2007-07-30, Version 4.0.6
1258 * sensors plugin: Fix the ignorelist functionality: Only the `type
1259 instance' was used to match against the list, but the documentation
1260 told otherwise. This release fixes the code, so it complies with the
1262 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1263 configuration messages will end up in the logging facility.
1264 * conrtib/fedora: The contributed specfile for Fedora has been
1267 2007-07-05, Version 4.0.5
1268 * Portability: More fixes for OpenBSD have been included.
1270 2007-06-24, Version 4.0.4
1271 * cpu plugin: Fixed the Solaris code.
1272 * dns plugin: Fixed a build issue for OpenBSD.
1273 * interface plugin: Fixed the Solaris code.
1274 * load plugin: Fixed the alternative `/proc' Linux code.
1275 * memory plugin: Fixed the Solaris code.
1276 * oconfig: Don't require `-lfl' anymore.
1278 2007-06-19, Version 4.0.3
1279 * cpu plugin: Fix the Darwin / Mac OS X code.
1280 * ping plugin: Use the return value of `getpid', not its address.
1281 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1282 initialized correctly.
1283 * configure: Added `--with-nan-emulation' to aid cross compilation.
1285 2007-06-12, Version 4.0.2
1286 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1287 they're given in numerically form.
1289 2007-06-07, Version 4.0.1
1290 * iptables plugin: A bug in the configuration routine has been fixed.
1291 Setting a comment in the configfile will no longer cause a
1294 2007-06-03, Version 4.0.0
1295 * collectd: The plugin-infrastructure has been changed to allow for
1296 more types of plugins, namely `write' and `log' plugins.
1297 * collectd: The read-function has been changed to read many plugins in
1298 parallel, using threads. Thus, plugins generally need to use
1299 thread-safe functions from now on.
1300 * collectd: The '-t' command line options allows to perform syntax tests
1301 of the configuration file and exit immediately.
1302 * csv plugin: The new `csv' plugin handles output to `comma separated
1304 * rrdtool plugin: The new `rrdtool' plugin handles output to
1305 RRD-files. Data can be cached to combine multiple updates into one
1306 write to increase IO-performance.
1307 * network plugin: The new `network' plugin handles IO via the network.
1308 It implements a different, much more extensible protocol which can
1309 combine many values in one packet, decreasing the number of UDP-
1310 packets being sent. It can read from and send to the network and
1311 with the appropriate configuration even forward packets to other
1313 * unixsock plugin: The new `unixsock' plugin provides an interface to
1314 communicate with the daemon while it is running. Right now the
1315 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1317 * perl plugin: The new `perl' plugin allows you to write extensions
1318 for collectd in the scripting-language Perl.
1319 * logfile plugin: The new `logfile' plugin writes logmessages to files
1320 or STDOUT or STDERR.
1321 * syslog plugin: The new `syslog' plugin sends logmessages to the
1322 system's syslog daemon.
1323 * entropy plugin: The new `entropy' plugin collects the amount of
1324 entropy currently being available to the system.
1325 * exec plugin: The new `exec' plugin forks child processes and reads
1326 back values provided by the forked processes.
1327 * iptables plugin: The new `iptables' plugin reads counters from
1328 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1330 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1331 to Peter Holik for contributing this plugin.
1332 * nut plugin: The new `nut' plugin connects the upsd of the `network
1333 ups tools' and reads information about the connected UPS.
1334 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1335 connections) field was added by Florent Monbillard.
1336 * collectd-nagios: The new `collectd-nagios' binary queries values
1337 from collectd, parses them and exits according to Nagios-standards.
1338 * manpages: The manpages have been improved a lot.
1340 2007-09-28, Version 3.11.7
1341 * wireless plugin: Correct the handling of cards returning signal and
1342 noise quality as percentage.
1344 2007-08-31, Version 3.11.6
1345 * processes plugin: Fix a potential segmentation fault.
1347 2007-05-29, Version 3.11.5
1348 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1349 * ntpd plugin: Fix a potential buffer overflow.
1350 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1351 were accounted as `zombies'.
1353 2007-04-10, Version 3.11.4
1354 * dns plugin: Change the order of includes to make the plugin compile
1357 2007-03-30, Version 3.11.3
1358 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1359 of the unused `COLLECT_KSTAT'.
1361 2007-02-11, Version 3.11.2
1362 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1363 NULL-pointer may have been passed to `printf' which causes a
1364 segfault with some libcs.
1366 2007-02-10, Version 3.11.1
1367 * df plugin: Some wrong defines have been fixed so the plugin works
1368 under Solaris again.
1369 * dns plugin: The usage of a struct has been fixed to work with
1371 * processes plugin: Some missing defines have been added so the plugin
1372 compiles cleanly under FreeBSD and presumably other UNIXes.
1374 2006-12-22, Version 3.11.0
1375 * collectd: The new command line option `-P' makes it easier for
1376 distributors to change the location of PID-files.
1377 * collectd: The daemon shuts down faster now which makes it easier to
1378 write init.d-scripts for it.
1379 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1380 caused problems every now and then.
1381 * df plugin: New config options allow to ignore certain mountpoints,
1382 filesystem types or devices.
1383 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1384 and interprets it. It collects traffic as well as qtype, opcode and
1386 * email plugin: Sebastian Harl has contributed this plugin which
1387 counts received mails in categories (e. g. ham, spam, virus), spam
1388 score (as given by SpamAssassin) and check types.
1389 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1390 uses `mbmon' to gather information from sensors on the motherboard.
1391 * processes plugin: Collect detailed statistics for configured
1392 processes, that's process and thread count, CPU usage, resident
1393 segment size and pagefaults.
1394 * multimeter plugin: Peter Holik contributed a new plugin which
1395 queries multimeters.
1396 * sensors plugin: Lubos Stanek has put much effort into improving this
1397 plugin, including `extended naming', collection of voltage values
1398 and the possibility to ignore certain values.
1400 2006-12-21, Version 3.10.4
1401 * Max Kellermann has identified a bug in the server routine: When
1402 opening a socket fails the daemon will (re)try opening the socket in
1403 an endless loop, ultimately leading to a `EMFILE' error.
1405 2006-11-04, Version 3.10.3
1406 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1407 ntpd's reply was sent in more than one packet, the buffer size was
1408 calculated incorrectly, resulting in the reading of uninitialized or
1411 2006-11-01, Version 3.10.2
1412 * The sample config file has been improved.
1413 * Errors in the manpages have been corrected.
1414 * The ping-plugin now adds hosts during initialization, not during
1415 startup. This speeds up startup when no network connectivity is
1416 available. Also, the hosts are being added later when the network is
1418 * Improved BSD-support for the df-plugin.
1419 * Fixed syntax errors in the swap-plugin for Mac OS X.
1420 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1422 * Don't disable the mysql-plugin if connecting to the database fails
1423 during initialization. Instead, try again in increasing intervals.
1425 2006-07-19, Version 3.10.1
1426 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1427 the apcups cannot be reached, unconnected sockets will pile up and
1428 eventually lead to `Too many open files' errors.
1430 2006-07-09, Version 3.10.0
1431 * The `disk' plugin has been ported to Darwin.
1432 * The `battery' plugin should work on many Apple computers now.
1433 * The `traffic' plugin can now ignore certain interfaces. Also,
1434 statistics for sent/received packets and errors have been added.
1435 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1436 to Anthony Gialluca for contributing this plugin and providing me
1437 with a test environment :)
1438 * A plugin for monitoring an NTP instance and the local clock drift
1441 2006-06-25, Version 3.9.4
1442 * The Solaris code in the `swap' plugin has been changed to reflect
1443 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1445 * The debugging system has been fixed to work with the Sun libc.
1446 * When built without librrd the variable `operating_mode' could be
1447 uninitialized. Thanks to David Elliot for reporting the bug.
1449 2006-06-01, Version 3.9.3
1450 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1451 operating systems also profit from the changes, but I wasn't able to
1453 * Changed the build system to find the netinet-includes under FreeBSD
1454 and therefore successfully build the `liboping' library there.
1456 2006-05-09, Version 3.9.2
1457 * Applied a patch to the `liboping' library. Due to a bug in the
1458 sequence checking the `ping' plugin stopped working after
1459 approximately 7.6 days.
1461 2006-05-09, Version 3.8.5
1462 * Applied a patch to the `liboping' library. Due to a bug in the
1463 sequence checking the `ping' plugin stopped working after
1464 approximately 7.6 days.
1466 2006-04-21, Version 3.9.1
1467 * Build issues with Solaris and possible other architectures have been
1469 * Problems when building the `apache'-plugin without `libcurl' have
1471 * A bug in the `ping' plugin has been fixed. Sorry folks.
1473 2006-04-02, Version 3.9.0
1474 * A plugin to monitor the Apache webserver has been added.
1475 <http://httpd.apache.org/>
1476 * A plugin to collect statistics about virtual servers using VServer.
1477 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1479 * A plugin for wireless LAN cards has been added. It monitors signal
1480 strength, link quality and noise ratio..
1481 * A plugin for Apple hardware sensors has been added.
1482 * An option to compile collectd with different `step' and `heartbeat'
1483 settings has been added. The size of RRAs is no longer static but
1484 calculated based on the settings for `step' and `width'.
1485 * The `ping' plugin can now be configured to use a certain TTL.
1486 * A plugin to monitor the hardware sensors of Apple computers has been
1488 * The plugins `cpu', `memory', `processes' and `traffic' have been
1489 ported to Mach/Darwin (Mac OS X).
1490 * The `log mode' has been contributed by Christophe Kalt. It writes
1491 the data into text files rather than RRD files.
1493 2006-04-09, Version 3.8.4
1494 * Applied patch by Vincent Stehlé which improves the disk-name
1495 resolution in the `hddtemp' plugin for Linux systems.
1497 2006-04-02, Version 3.8.3
1498 * Applied a patch by James Byers: The MySQL plugin was not working
1499 with MySQL 5.0.2 or later.
1501 2006-03-14, Version 3.8.2
1502 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1503 the GNU libc, because it points to `/etc/fstab' rather than
1506 2006-03-13, Version 3.8.1
1507 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1508 * Fixes in the debian `postinst' and `init.d' scripts.
1510 2006-03-09, Version 3.8.0
1511 * The `ping' plugin no longer uses `libping' but a self written
1512 library named `liboping'. With this library it's possible to ping
1513 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1515 2006-02-18, Version 3.7.2
1516 * A simple bug in the `battery' plugin has been fixed. It should now
1517 work with ACPI based batteries as well. Thanks to Sebastian for
1519 * Fixing a bug that prevented collectd to be built without librrd.
1520 Thanks to Werner Heuser for reporting it.
1522 2006-02-04, Version 3.7.1
1523 * The new network code has been improved to build with older versions
1525 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1526 to Tommie Gannert for this patch.
1528 2006-01-30, Version 3.7.0
1529 * The `battery' plugin has been added. It collects information about
1531 * The MySQL plugin has been improved: It now writes two more RRD
1532 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1533 * The `cpufreq' plugin now reads another file since the file it did
1534 read so far causes much overhead in the kernel. Also, you need root
1535 to read the old file, but not to read the new one.
1536 * The `hddtemp' plugin can now be configured to connect to another
1537 address and/or port than localhost.
1538 * The `df' plugin now prefers `statvfs' over `statfs'.
1539 * The network code has been rewritten. collectd now supports unicast
1540 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1541 be set in the configfile.
1543 2006-01-24, Version 3.6.2
1544 * Due to a bug in the configfile handling collectd wouldn't start in
1545 client mode. This released fixes this.
1547 2006-01-20, Version 3.6.1
1548 * Due to a bug in `configure.in' all modules and the binary were
1549 linked against `libmysqlclient'. This issue is solved by this
1552 2006-01-17, Version 3.6.0
1553 * A config file has been added. This allows for loading only specific
1555 * A `df' plugin has been added.
1556 * A `mysql' plugin has been added.
1557 * The `ping' plugin doesn't entirely give up hope when a socket error
1558 occurred, but will back of and increase the intervals between tries.
1560 2006-01-21, Version 3.5.2
1561 * Fixed yet another bug in the signal handling.. Stupid typo..
1562 * Improved the ping plugin to not give up on socket errors (backport
1565 2005-12-18, Version 3.5.1
1566 * The PID-file is now deleted correctly when shutting down the daemon.
1567 * SIGINT and SIGTERM are now handled correctly.
1569 2005-12-16, Version 3.5.0 (Revision 326)
1570 * A bug in the `load' module under Solaris has been fixed.
1571 * The `users' module has been contributed by Sebastian Harl. It counts
1572 currently logged in users.
1573 * The CPU module now works under FreeBSD without the use of
1574 `libstatgrab', however SMP support is missing.
1575 * The default directories for the RRD files and the PID file now
1576 depend on the compile time setting of `localstatedir'.
1578 2005-11-15, Version 3.4.0 (Revision 236)
1579 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1580 from gentoo's bugzilla for writing the patch.
1581 * The build dependency for librrd has been removed. Binaries built
1582 without librrd are client-only and will multicast their value as
1583 with the `-c' argument.
1584 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1585 * The newly introduced `-f' switch prevents daemon initialization
1586 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1587 Barcellos for this patch.
1589 2005-11-04, Version 3.3.0 (Revision 216)
1590 * New modules have been added:
1591 - `serial', for monitoring traffic on the serial interfaces
1592 - `nfs', for graphing NFS procedure calls
1593 - `tape', traffic from/to tape devices
1594 * The memory.rrd now accepts more than 4Gig of memory.
1596 2005-10-26, Version 3.2.0 (Revision 200)
1597 * Support for graphing the processes has been added (thanks to Lyonel
1599 * If reading from hddtemp fails collectd will increase the time
1600 between polls up to one day.
1601 * The init.d files have been improved.
1602 * Problems with the spec file have been fixed.
1604 2005-10-16, Version 3.1.0 (Revision 194)
1605 * Added the `setsid' syscall to the startup code.
1606 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1608 2005-09-30, Version 3.0.0 (Revision 184)
1609 * The ability to send/receive data to/from the network (think
1610 multicast) has been added.
1611 * Modules have been split up into shared libraries can be loaded at
1612 runtime. The biggest advantage is that the core program doesn't need
1613 to be linked against an external library.
1614 * A patch by George Kargiotakis has been applied: It fixes the sensors
1615 behaviour then more than one sensor is being queried.
1617 2005-09-16, Version 2.1.0 (Revision 172)
1618 * A module for swap statistics has been added.
1620 2005-09-09, Version 2.0.0 (Revision 135)
1621 * Filenames can no longer be configured at program startup. The only
1622 options as of this version are the directory and ping hosts.
1623 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1624 Soft-IRQ statistics are added to `System'.
1625 * Diskstats now collect read and write bytes, not sectors.
1626 * Ping statistics can now be collected for more than one host. There
1627 is no default any more: If no host is given no host will be pinged.
1628 * A self-written patch for libping has been applied so it builds
1631 2005-09-01, Version 1.8.1 (Revision 123)
1632 * Much improved configure-script: libraries and features may now be
1634 * More detailed warnings/error messages when RRD update fails.
1636 2005-08-29, Version 1.8.0:
1637 * Support for collecting disk statistics under Solaris.
1639 2005-08-25, Version 1.7.0:
1640 * Support for libstatgrab[1] for load, memory usage and network
1641 traffic. CPU- and disk-usage are not (yet) supported, since
1642 libstatgrab returns insufficient information. I will contact the
1644 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1645 aren't necessarily counted linear which is now handled correctly.
1646 [1]: http://www.i-scream.org/libstatgrab/
1648 2005-08-21, Version 1.6.0:
1649 * Basic support for Solaris: System load and cpu-usage can be
1650 collected under Solaris, too. Other stats will follow later.
1651 * Many fixes in the autoconf-script
1652 * Collection/Museum scripts have been added under contrib/museum
1653 * collectd may now be started in unprivileged mode, though ping
1654 statistics will not work.
1656 2005-07-17, Version 1.5.1:
1657 * Diskstats-RRDs now use major/minor for naming. Some systems have
1658 weird strings as disk-names..
1660 2005-07-17, Version 1.5:
1661 * A new module, diskstats, has been added. It collects information
1662 about the disks and partitions.
1664 2005-07-11, Version 1.4.2:
1665 * The meminfo module has been changed to work with more platforms
1666 and/or kernel versions.
1668 2005-07-10, Version 1.4.1: Correct traffic stats
1669 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1670 forgot to correct when I changed that module.
1672 2005-07-09, Version 1.4: More traffic stats
1673 * Traffic is now collected for all interfaces that can be found
1674 * Temperature-statistics are read from lm-sensors if available
1676 2005-07-08, Version 1.3: CPU stats
1677 * Collecting CPU statistics now
1679 2005-07-12, Version 1.2: Using syslog
1680 * collectd is now using the syslog facility to report errors, warnings
1682 * The default directory is now /var/db/collectd
1684 2005-07-10, Version 1.1: Minor changes
1685 * Nothing really useful to say ;)
1687 2005-07-09, Version 1.0: Initial Version
1688 * The following modules are provided:
