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

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

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

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

819 code. Thanks to "thated" for reporting this.
821 2009-01-02, Version 4.5.2
822 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
823 file may be in both locations, especially when the database was
824 installed in a non-standard path. Thanks to Dusty Doris for
826 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
827 Solaris, in the configure script automatically.
828 * build system, tcpconns plugin: Check for `kvm_nlist' and
829 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM

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

853 2008-10-16, Version 4.5.1
854 * build system: Change `--enable-<plugin>' to abort with an error if
855 dependencies are not met. Thanks to Bruno Prémont for the patch.
856 Also, the poisoning of various string functions has been restricted

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

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

1013 sensor values via IPMI, the intelligent platform management
1015 * iptables plugin: The iptc library that is used by the iptables
1016 plugin has been added to the distribution, because it is not
1017 provided by all distributions and removed from at least one.
1018 * powerdns plugin: The new powerdns plugin reads statistics from an
1019 authoritative or a recursing PowerDNS name server.
1020 * rrdtool plugin: The size of the files generated with the default
1021 configuration has been decreased.
1022 * tail plugin: The new tail plugin can be used to gather statistics by
1023 continuously reading from log files.
1024 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1025 TeamSpeak2 server and collects statistics about the number of users
1026 and number of channels.
1027 * users plugin: Support for the statgrab library has been added.
1028 * vmem plugin: The new vmem plugin collects very detailed statistics
1029 about the virtual memory subsystem of Linux.
1031 2008-08-30, Version 4.3.4
1032 * Build system: Improved detection of and linking with the statgrab
1034 * collectd: Portability fixes, especially to determine endianess more
1036 * Various plugins: Fix format strings.
1037 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1038 again has been applied.
1039 * memcached plugin: Fix a too short timeout and a related file
1041 * memory plugin: A typo in the libstatgrab code has been fixed.
1042 * network plugin: A fix in the initialization function solves problems
1044 * nginx plugin: A thread-unsafe function has been replaced.
1045 * vserver plugin: A thread-unsafe function has been replaced.
1046 * wireless plugin: A work-around for broken wireless drivers has been
1049 2008-04-22, Version 4.3.3
1050 * build system: Improved detection of several libraries, especially if
1051 they are in non-standard paths.
1052 * build system: Portability fixes: Automatically define "_REENTRANT"
1053 if the libc expects it.
1054 * collectd: Error and warning messages have been improved.
1055 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1057 * apache plugin: Allocate new memory when reading a webpage instead of
1058 using a buffer of static size.
1059 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1061 * hddtemp plugin: Error and warning messages have been improved.
1062 * sensors plugin: Fix sensor collection for some chip types.
1064 2008-03-29, Version 4.3.2
1065 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1066 `Persist' threshold options.
1067 * collectd: Fix handling of missing values in the global value cache.
1068 * collectd: Improved error messages when parsing the configuration.
1069 * sensors plugin: Fix temperature collection with libsensors4.
1070 * unixsock plugin: Fix mixed input and output operation on streams.
1071 * wireless plugin: Fix reading noise value.
1073 2008-03-05, Version 4.3.1
1074 * exec plugin: Set supplementary group IDs.
1076 + Use `memcpy' when constructing/parsing a package to avoid
1077 alignment problems on weird architectures, such as Sparc.
1078 + Translate doubles to/from the x86 byte representation to ensure
1079 cross-platform compatibility.
1080 * ping plugin: Correct the handling of the `TTL' setting.
1081 * swap plugin: Reapply a patch for Solaris.
1082 * tcpconns plugin: Portability improvements.
1084 2008-02-18, Version 4.3.0
1085 * collectd: Notifications have been added to the daemon. Notifications
1086 are status messages that may be associated with a data instance.
1087 * collectd: Threshold checking has been added to the daemon. This
1088 means that you can configure threshold values for each data
1089 instance. If this threshold is exceeded a notification will be
1091 * collectd: The new `FQDNLookup' option tells the daemon to use the
1092 full qualified domain name as the hostname, not just the host part
1093 es returned by `gethostname(2)'.
1094 * collectd: Support for more than one `TypesDB' file has been added.
1095 This is useful when one such file is included in a package but one
1096 wants to add custom type definitions.
1097 * collectd: The `Include' config option has been expanded to handle
1098 entire directories and shell wildcards.
1099 * collectdmon: The new `collectdmon' binary detects when collectd
1100 terminates and automatically restarts it again.
1101 * csv plugin: The CSV plugin is now able to store counter values as a
1102 rate, using the `StoreRates' configuration option.
1103 * exec plugin: Handling of notifications has been added and the
1104 ability to pass arguments to the executed programs has been added.
1105 * hddtemp plugin: The new `TranslateDevicename' option lets you
1106 disable the translation from device names to major-minor-numbers.
1107 * logfile plugin: Handling of notifications has been added.
1108 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1109 domain name lookups in this plugin.
1110 * perl plugin: Many internal changes added support for handling multiple
1111 threads making the plugin reasonably usable inside collectd. The API has
1112 been extended to support notifications and export global variables to
1113 Perl plugins; callbacks now have to be identified by name rather than a
1114 pointer to a subroutine. The plugin is no longer experimental.
1115 * uuid plugin: The new UUID plugin sets the hostname to an unique
1116 identifier for this host. This is meant for setups where each client
1117 may migrate to another physical host, possibly going through one or
1118 more name changes in the process. Thanks to Richard Jones from
1119 Red Hat's Emerging Technology group for this plugin.
1120 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1121 CPU, disk and network statistics about guest systems on the same
1122 physical server. Thanks to Richard Jones from Red Hat's Emerging
1123 Technology group for this plugin.
1125 2008-04-22, Version 4.2.7
1126 * build system: Improved detection of several libraries, especially if
1127 they are in non-standard paths.
1128 * build system: Portability fixes: Automatically define "_REENTRANT"
1129 if the libc expects it.
1130 * collectd: Error and warning messages have been improved.
1131 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1133 * apache plugin: Allocate new memory when reading a webpage instead of
1134 using a buffer of static size.
1135 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1137 * hddtemp plugin: Error and warning messages have been improved.
1138 * sensors plugin: Fix sensor collection for some chip types.
1140 2008-03-29, Version 4.2.6
1141 * collectd: Improved error messages when parsing the configuration.
1142 * sensors plugin: Fix temperature collection with libsensors4.
1143 * unixsock plugin: Fix mixed input and output operation on streams.
1144 * wireless plugin: Fix reading noise value.
1146 2008-03-04, Version 4.2.5
1147 * apache plugin: Improved initialization and error messages.
1148 * exec plugin: Set supplementary group IDs.
1150 + Create separate threads for reading from the socket and parsing
1151 and dispatching incoming packets. Versions prior to this may have
1152 problems in high-load situations, where the socket receive buffers
1153 overflows, resulting in gaps in the data.
1154 + Use `memcpy' when constructing/parsing a package to avoid
1155 alignment problems on weird architectures, such as Sparc.
1156 + Translate doubles to/from the x86 byte representation to ensure
1157 cross-platform compatibility.
1158 * ping plugin: Correct the handling of the `TTL' setting.
1159 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1160 * swap plugin: Reapply a patch for Solaris.
1161 * tcpconns plugin: Portability improvements.
1163 2008-01-21, Version 4.2.4
1164 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1165 the permission on the socket as documented in the manpage. Thanks to
1166 Evgeny Chukreev for fixing this issue.
1167 * collectd: The documentation has been improved.
1169 2007-12-28, Version 4.2.3
1170 * sensors plugin: Updated the plugin to build and work with version 3
1171 of the libsensors library.
1173 2007-12-15, Version 4.2.2
1174 * nginx plugin: Incorrect comparison of strings lead to a segfault
1175 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1177 * logfile plugin: The config option `Timestamp' was handled
1178 incorrectly and basically always active. Thanks to Luke Heberling
1181 2007-11-08, Version 4.2.1
1182 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1183 enabled on the host.
1184 * snmp plugin: Fix a memory leak.
1186 2007-10-27, Version 4.2.0
1187 * collectd: The new config option `Include' lets you include other
1188 configfiles and thus split up your config into smaller parts. This
1189 may be especially interesting for the snmp plugin to keep the data
1190 definitions separate from the host definitions.
1191 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1192 (number of connections, octets and packets for each service and
1193 destination). Thanks to Sebastian Harl for this plugin.
1194 * memcached plugin: The new `memcached' plugin connects to a memcached
1195 daemon process and collects statistics of this distributed caching
1196 system. Thanks to Antony Dovgal for contributing this plugin.
1197 * nginx plugin: The new `nginx' plugin reads the status page of an
1198 nginx daemon and saves the handled connections and requests.
1199 * perl plugin: Many changes, including the added `EnableDebugger'
1200 config option which lets you debug your Perl plugins more easily.
1201 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1202 be more thread-safe otherwise by locking calls to the library.
1203 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1204 correct the values returned by SNMP-agents. If a <data> block is
1205 defined as `table' the instance is now optional. The sequence number
1206 is used as the type-instance in this case. The new `InstancePrefix'
1207 option allows to add arbitrary prefixes to the type-instance.
1208 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1209 certain TCP connections and what state they're in. This can be used
1210 to see how many connections your FTP server has to handle or how
1211 many outgoing connections your mailserver has open.
1213 2008-01-11, Version 4.1.6
1214 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1215 the permission on the socket as documented in the manpage. Thanks to
1216 Evgeny Chukreev for fixing this issue.
1217 * collectd: The documentation has been improved.
1219 2007-12-27, Version 4.1.5
1220 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1222 * sensors plugin: Updated the plugin to build and work with version 3
1223 of the libsensors library.
1225 2007-11-08, Version 4.1.4
1226 * Build system: Improve detection of the rrd library, especially if
1227 it's in a non-standard location.
1228 * Build system: A bug when parsing the argument for
1229 `--with-libnetsnmp' has been fixed.
1230 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1231 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1232 a deadlock or delay when shutting down the daemon.
1233 * snmp plugin: Fix a memory leak.
1235 2007-10-24, Version 4.1.3
1236 * collectd: A build issue under Solaris has been resolved by renaming
1238 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1239 be more thread-safe otherwise by locking calls to the library.
1241 2007-09-28, Version 4.1.2
1242 * apcups plugin: Fix reporting of the `load percent' data.
1243 * wireless plugin: Correct the handling of cards returning signal and
1244 noise quality as percentage.
1245 * perl plugin: Fix a possible buffer overflow in get_module_name().
1246 * build system: Further improve the detection of libraries.
1247 * netlink plugin: Build issues under some older versions of the Linux
1248 includes (i. e. Debian Sarge) have been fixed.
1249 * snmp plugin: Fix a potential segfault when a host times out. Add
1250 support for the `timeticks' type.
1252 2007-09-12, Version 4.1.1
1253 * Build system: The detection of `libnetlink' has been improved.
1254 * collectd: The documentation has been fixed in numerous places.
1255 * exec plugin: Setting the group under which to run a program has been
1257 * collectd: The `sstrerror' function was improved to work correctly
1258 with the broken GNU version of `strerror_r'.
1259 * collectd: Write an error message to STDERR when loading of a plugin
1261 * apcups plugin: Fix the `types' used to submit the values: They still
1262 has an `apcups_' prefix which doesn't work anymore.
1263 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1264 whatever the client thinks is `now'..
1266 2007-09-01, Version 4.1.0
1267 * Build system: The build system has been changed to automatically
1268 disable all plugins, which are missing dependencies. The dependency
1269 checking has been removed from the plugins themselves to remove
1271 * Flexible interval: The interval of collected data is now sent along
1272 with the data itself over the network, so that the interval-settings
1273 of server and clients no longer needs to match.
1274 * netlink plugin: The new `netlink' plugin connects to the Linux
1275 kernel using a netlink socket and uses it to query information about
1276 interfaces, qdiscs and classes.
1277 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1278 to not block data collection.
1279 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1280 network devices, such as switches, routers, thermometers, rack
1281 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1283 * unixsock plugin: Added the `LISTVAL' command.
1284 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1285 of music played with xmms.
1287 2007-09-28, Version 4.0.9
1288 * apcups plugin: Fix reporting of the `load percent' data.
1289 * wireless plugin: Correct the handling of cards returning signal and
1290 noise quality as percentage.
1291 * perl plugin: Fix a possible buffer overflow in get_module_name().
1293 2007-09-12, Version 4.0.8
1294 * collectd: The `sstrerror' function was improved to work correctly
1295 with the broken GNU version of `strerror_r'.
1296 * collectd: Write an error message to STDERR when loading of a plugin
1298 * apcups plugin: Fix the `types' used to submit the values: They still
1299 has an `apcups_' prefix which doesn't work anymore.
1300 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1301 whatever the client thinks is `now'..
1303 2007-08-26, Version 4.0.7
1304 * documentation: Some typos have been fixed and some information has
1306 * build system: Many fixes for detecting libraries in unusual places,
1307 such as on RedHat systems. The affected libraries are `libcurl',
1308 `libmysql', and `libupsclient'.
1309 * network plugin: Allow the `Port' option to be specified as a number
1310 (i. e. without quotes).
1311 * nut plugin: A fix allows linking the nut plugin against
1312 libupsclient, version >= 2.2.0.
1313 * processes plugin: Fix a potential segmentation fault.
1315 2007-07-30, Version 4.0.6
1316 * sensors plugin: Fix the ignorelist functionality: Only the `type
1317 instance' was used to match against the list, but the documentation
1318 told otherwise. This release fixes the code, so it complies with the
1320 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1321 configuration messages will end up in the logging facility.
1322 * conrtib/fedora: The contributed specfile for Fedora has been
1325 2007-07-05, Version 4.0.5
1326 * Portability: More fixes for OpenBSD have been included.
1328 2007-06-24, Version 4.0.4
1329 * cpu plugin: Fixed the Solaris code.

1331 * interface plugin: Fixed the Solaris code.
1332 * load plugin: Fixed the alternative `/proc' Linux code.
1333 * memory plugin: Fixed the Solaris code.
1334 * oconfig: Don't require `-lfl' anymore.
1336 2007-06-19, Version 4.0.3
1337 * cpu plugin: Fix the Darwin / Mac OS X code.
1338 * ping plugin: Use the return value of `getpid', not its address.
1339 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1340 initialized correctly.
1341 * configure: Added `--with-nan-emulation' to aid cross compilation.
1343 2007-06-12, Version 4.0.2
1344 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1345 they're given in numerically form.
1347 2007-06-07, Version 4.0.1
1348 * iptables plugin: A bug in the configuration routine has been fixed.
1349 Setting a comment in the configfile will no longer cause a
1352 2007-06-03, Version 4.0.0
1353 * collectd: The plugin-infrastructure has been changed to allow for
1354 more types of plugins, namely `write' and `log' plugins.
1355 * collectd: The read-function has been changed to read many plugins in
1356 parallel, using threads. Thus, plugins generally need to use
1357 thread-safe functions from now on.
1358 * collectd: The '-t' command line options allows to perform syntax tests
1359 of the configuration file and exit immediately.
1360 * csv plugin: The new `csv' plugin handles output to `comma separated
1362 * rrdtool plugin: The new `rrdtool' plugin handles output to
1363 RRD-files. Data can be cached to combine multiple updates into one
1364 write to increase IO-performance.
1365 * network plugin: The new `network' plugin handles IO via the network.
1366 It implements a different, much more extensible protocol which can
1367 combine many values in one packet, decreasing the number of UDP-
1368 packets being sent. It can read from and send to the network and
1369 with the appropriate configuration even forward packets to other
1371 * unixsock plugin: The new `unixsock' plugin provides an interface to
1372 communicate with the daemon while it is running. Right now the
1373 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1375 * perl plugin: The new `perl' plugin allows you to write extensions
1376 for collectd in the scripting-language Perl.
1377 * logfile plugin: The new `logfile' plugin writes logmessages to files
1378 or STDOUT or STDERR.
1379 * syslog plugin: The new `syslog' plugin sends logmessages to the
1380 system's syslog daemon.
1381 * entropy plugin: The new `entropy' plugin collects the amount of
1382 entropy currently being available to the system.
1383 * exec plugin: The new `exec' plugin forks child processes and reads
1384 back values provided by the forked processes.
1385 * iptables plugin: The new `iptables' plugin reads counters from
1386 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1388 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1389 to Peter Holik for contributing this plugin.
1390 * nut plugin: The new `nut' plugin connects the upsd of the `network
1391 ups tools' and reads information about the connected UPS.
1392 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1393 connections) field was added by Florent Monbillard.
1394 * collectd-nagios: The new `collectd-nagios' binary queries values
1395 from collectd, parses them and exits according to Nagios-standards.
1396 * manpages: The manpages have been improved a lot.
1398 2007-09-28, Version 3.11.7
1399 * wireless plugin: Correct the handling of cards returning signal and
1400 noise quality as percentage.
1402 2007-08-31, Version 3.11.6
1403 * processes plugin: Fix a potential segmentation fault.
1405 2007-05-29, Version 3.11.5
1406 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1407 * ntpd plugin: Fix a potential buffer overflow.
1408 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1409 were accounted as `zombies'.
1411 2007-04-10, Version 3.11.4
1412 * dns plugin: Change the order of includes to make the plugin compile
1415 2007-03-30, Version 3.11.3
1416 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1417 of the unused `COLLECT_KSTAT'.
1419 2007-02-11, Version 3.11.2
1420 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1421 NULL-pointer may have been passed to `printf' which causes a
1422 segfault with some libcs.
1424 2007-02-10, Version 3.11.1
1425 * df plugin: Some wrong defines have been fixed so the plugin works
1426 under Solaris again.
1427 * dns plugin: The usage of a struct has been fixed to work with
1429 * processes plugin: Some missing defines have been added so the plugin
1430 compiles cleanly under FreeBSD and presumably other UNIXes.
1432 2006-12-22, Version 3.11.0
1433 * collectd: The new command line option `-P' makes it easier for
1434 distributors to change the location of PID-files.
1435 * collectd: The daemon shuts down faster now which makes it easier to
1436 write init.d-scripts for it.
1437 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1438 caused problems every now and then.
1439 * df plugin: New config options allow to ignore certain mountpoints,
1440 filesystem types or devices.
1441 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1442 and interprets it. It collects traffic as well as qtype, opcode and
1444 * email plugin: Sebastian Harl has contributed this plugin which
1445 counts received mails in categories (e. g. ham, spam, virus), spam
1446 score (as given by SpamAssassin) and check types.
1447 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1448 uses `mbmon' to gather information from sensors on the motherboard.
1449 * processes plugin: Collect detailed statistics for configured
1450 processes, that's process and thread count, CPU usage, resident
1451 segment size and pagefaults.
1452 * multimeter plugin: Peter Holik contributed a new plugin which
1453 queries multimeters.
1454 * sensors plugin: Lubos Stanek has put much effort into improving this
1455 plugin, including `extended naming', collection of voltage values
1456 and the possibility to ignore certain values.
1458 2006-12-21, Version 3.10.4
1459 * Max Kellermann has identified a bug in the server routine: When
1460 opening a socket fails the daemon will (re)try opening the socket in
1461 an endless loop, ultimately leading to a `EMFILE' error.
1463 2006-11-04, Version 3.10.3
1464 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1465 ntpd's reply was sent in more than one packet, the buffer size was
1466 calculated incorrectly, resulting in the reading of uninitialized or
1469 2006-11-01, Version 3.10.2
1470 * The sample config file has been improved.
1471 * Errors in the manpages have been corrected.
1472 * The ping-plugin now adds hosts during initialization, not during
1473 startup. This speeds up startup when no network connectivity is
1474 available. Also, the hosts are being added later when the network is
1476 * Improved BSD-support for the df-plugin.
1477 * Fixed syntax errors in the swap-plugin for Mac OS X.
1478 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1480 * Don't disable the mysql-plugin if connecting to the database fails
1481 during initialization. Instead, try again in increasing intervals.
1483 2006-07-19, Version 3.10.1
1484 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1485 the apcups cannot be reached, unconnected sockets will pile up and
1486 eventually lead to `Too many open files' errors.
1488 2006-07-09, Version 3.10.0
1489 * The `disk' plugin has been ported to Darwin.
1490 * The `battery' plugin should work on many Apple computers now.
1491 * The `traffic' plugin can now ignore certain interfaces. Also,
1492 statistics for sent/received packets and errors have been added.

1494 to Anthony Gialluca for contributing this plugin and providing me
1495 with a test environment :)
1496 * A plugin for monitoring an NTP instance and the local clock drift
1499 2006-06-25, Version 3.9.4
1500 * The Solaris code in the `swap' plugin has been changed to reflect
1501 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1503 * The debugging system has been fixed to work with the Sun libc.
1504 * When built without librrd the variable `operating_mode' could be
1505 uninitialized. Thanks to David Elliot for reporting the bug.
1507 2006-06-01, Version 3.9.3
1508 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1509 operating systems also profit from the changes, but I wasn't able to
1511 * Changed the build system to find the netinet-includes under FreeBSD
1512 and therefore successfully build the `liboping' library there.
1514 2006-05-09, Version 3.9.2
1515 * Applied a patch to the `liboping' library. Due to a bug in the
1516 sequence checking the `ping' plugin stopped working after
1517 approximately 7.6 days.
1519 2006-05-09, Version 3.8.5
1520 * Applied a patch to the `liboping' library. Due to a bug in the
1521 sequence checking the `ping' plugin stopped working after
1522 approximately 7.6 days.
1524 2006-04-21, Version 3.9.1
1525 * Build issues with Solaris and possible other architectures have been
1527 * Problems when building the `apache'-plugin without `libcurl' have
1529 * A bug in the `ping' plugin has been fixed. Sorry folks.
1531 2006-04-02, Version 3.9.0
1532 * A plugin to monitor the Apache webserver has been added.
1533 <http://httpd.apache.org/>
1534 * A plugin to collect statistics about virtual servers using VServer.
1535 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1537 * A plugin for wireless LAN cards has been added. It monitors signal
1538 strength, link quality and noise ratio..
1539 * A plugin for Apple hardware sensors has been added.
1540 * An option to compile collectd with different `step' and `heartbeat'
1541 settings has been added. The size of RRAs is no longer static but
1542 calculated based on the settings for `step' and `width'.
1543 * The `ping' plugin can now be configured to use a certain TTL.
1544 * A plugin to monitor the hardware sensors of Apple computers has been
1546 * The plugins `cpu', `memory', `processes' and `traffic' have been
1547 ported to Mach/Darwin (Mac OS X).
1548 * The `log mode' has been contributed by Christophe Kalt. It writes
1549 the data into text files rather than RRD files.
1551 2006-04-09, Version 3.8.4
1552 * Applied patch by Vincent Stehlé which improves the disk-name
1553 resolution in the `hddtemp' plugin for Linux systems.
1555 2006-04-02, Version 3.8.3
1556 * Applied a patch by James Byers: The MySQL plugin was not working
1557 with MySQL 5.0.2 or later.
1559 2006-03-14, Version 3.8.2
1560 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1561 the GNU libc, because it points to `/etc/fstab' rather than
1564 2006-03-13, Version 3.8.1
1565 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1566 * Fixes in the debian `postinst' and `init.d' scripts.
1568 2006-03-09, Version 3.8.0
1569 * The `ping' plugin no longer uses `libping' but a self written
1570 library named `liboping'. With this library it's possible to ping
1571 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1573 2006-02-18, Version 3.7.2
1574 * A simple bug in the `battery' plugin has been fixed. It should now
1575 work with ACPI based batteries as well. Thanks to Sebastian for
1577 * Fixing a bug that prevented collectd to be built without librrd.
1578 Thanks to Werner Heuser for reporting it.
1580 2006-02-04, Version 3.7.1
1581 * The new network code has been improved to build with older versions
1583 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1584 to Tommie Gannert for this patch.
1586 2006-01-30, Version 3.7.0
1587 * The `battery' plugin has been added. It collects information about
1589 * The MySQL plugin has been improved: It now writes two more RRD
1590 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1591 * The `cpufreq' plugin now reads another file since the file it did
1592 read so far causes much overhead in the kernel. Also, you need root
1593 to read the old file, but not to read the new one.
1594 * The `hddtemp' plugin can now be configured to connect to another
1595 address and/or port than localhost.
1596 * The `df' plugin now prefers `statvfs' over `statfs'.
1597 * The network code has been rewritten. collectd now supports unicast
1598 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1599 be set in the configfile.
1601 2006-01-24, Version 3.6.2
1602 * Due to a bug in the configfile handling collectd wouldn't start in
1603 client mode. This released fixes this.
1605 2006-01-20, Version 3.6.1
1606 * Due to a bug in `configure.in' all modules and the binary were
1607 linked against `libmysqlclient'. This issue is solved by this
1610 2006-01-17, Version 3.6.0
1611 * A config file has been added. This allows for loading only specific
1613 * A `df' plugin has been added.
1614 * A `mysql' plugin has been added.
1615 * The `ping' plugin doesn't entirely give up hope when a socket error
1616 occurred, but will back of and increase the intervals between tries.
1618 2006-01-21, Version 3.5.2
1619 * Fixed yet another bug in the signal handling.. Stupid typo..
1620 * Improved the ping plugin to not give up on socket errors (backport
1623 2005-12-18, Version 3.5.1
1624 * The PID-file is now deleted correctly when shutting down the daemon.
1625 * SIGINT and SIGTERM are now handled correctly.
1627 2005-12-16, Version 3.5.0 (Revision 326)
1628 * A bug in the `load' module under Solaris has been fixed.
1629 * The `users' module has been contributed by Sebastian Harl. It counts
1630 currently logged in users.
1631 * The CPU module now works under FreeBSD without the use of
1632 `libstatgrab', however SMP support is missing.
1633 * The default directories for the RRD files and the PID file now
1634 depend on the compile time setting of `localstatedir'.
1636 2005-11-15, Version 3.4.0 (Revision 236)
1637 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1638 from gentoo's bugzilla for writing the patch.
1639 * The build dependency for librrd has been removed. Binaries built
1640 without librrd are client-only and will multicast their value as
1641 with the `-c' argument.
1642 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1643 * The newly introduced `-f' switch prevents daemon initialization
1644 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1645 Barcellos for this patch.
1647 2005-11-04, Version 3.3.0 (Revision 216)
1648 * New modules have been added:
1649 - `serial', for monitoring traffic on the serial interfaces
1650 - `nfs', for graphing NFS procedure calls
1651 - `tape', traffic from/to tape devices
1652 * The memory.rrd now accepts more than 4Gig of memory.
1654 2005-10-26, Version 3.2.0 (Revision 200)
1655 * Support for graphing the processes has been added (thanks to Lyonel
1657 * If reading from hddtemp fails collectd will increase the time
1658 between polls up to one day.
1659 * The init.d files have been improved.
1660 * Problems with the spec file have been fixed.
1662 2005-10-16, Version 3.1.0 (Revision 194)
1663 * Added the `setsid' syscall to the startup code.
1664 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1666 2005-09-30, Version 3.0.0 (Revision 184)
1667 * The ability to send/receive data to/from the network (think
1668 multicast) has been added.
1669 * Modules have been split up into shared libraries can be loaded at
1670 runtime. The biggest advantage is that the core program doesn't need
1671 to be linked against an external library.
1672 * A patch by George Kargiotakis has been applied: It fixes the sensors
1673 behaviour then more than one sensor is being queried.
1675 2005-09-16, Version 2.1.0 (Revision 172)
1676 * A module for swap statistics has been added.
1678 2005-09-09, Version 2.0.0 (Revision 135)
1679 * Filenames can no longer be configured at program startup. The only
1680 options as of this version are the directory and ping hosts.
1681 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1682 Soft-IRQ statistics are added to `System'.
1683 * Diskstats now collect read and write bytes, not sectors.
1684 * Ping statistics can now be collected for more than one host. There
1685 is no default any more: If no host is given no host will be pinged.
1686 * A self-written patch for libping has been applied so it builds
1689 2005-09-01, Version 1.8.1 (Revision 123)
1690 * Much improved configure-script: libraries and features may now be
1692 * More detailed warnings/error messages when RRD update fails.
1694 2005-08-29, Version 1.8.0:
1695 * Support for collecting disk statistics under Solaris.
1697 2005-08-25, Version 1.7.0:
1698 * Support for libstatgrab[1] for load, memory usage and network
1699 traffic. CPU- and disk-usage are not (yet) supported, since
1700 libstatgrab returns insufficient information. I will contact the
1702 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1703 aren't necessarily counted linear which is now handled correctly.
1704 [1]: http://www.i-scream.org/libstatgrab/
1706 2005-08-21, Version 1.6.0:
1707 * Basic support for Solaris: System load and cpu-usage can be
1708 collected under Solaris, too. Other stats will follow later.
1709 * Many fixes in the autoconf-script
1710 * Collection/Museum scripts have been added under contrib/museum
1711 * collectd may now be started in unprivileged mode, though ping
1712 statistics will not work.
1714 2005-07-17, Version 1.5.1:
1715 * Diskstats-RRDs now use major/minor for naming. Some systems have
1716 weird strings as disk-names..
1718 2005-07-17, Version 1.5:
1719 * A new module, diskstats, has been added. It collects information
1720 about the disks and partitions.
1722 2005-07-11, Version 1.4.2:
1723 * The meminfo module has been changed to work with more platforms
1724 and/or kernel versions.
1726 2005-07-10, Version 1.4.1: Correct traffic stats
1727 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1728 forgot to correct when I changed that module.
1730 2005-07-09, Version 1.4: More traffic stats
1731 * Traffic is now collected for all interfaces that can be found
1732 * Temperature-statistics are read from lm-sensors if available
1734 2005-07-08, Version 1.3: CPU stats
1735 * Collecting CPU statistics now
1737 2005-07-12, Version 1.2: Using syslog
1738 * collectd is now using the syslog facility to report errors, warnings
1740 * The default directory is now /var/db/collectd
1742 2005-07-10, Version 1.1: Minor changes
1743 * Nothing really useful to say ;)
1745 2005-07-09, Version 1.0: Initial Version
1746 * The following modules are provided:
