769 name which prevented this match to be used as documented. Thanks to
770 Bruno Prémont for finding this problem.
771 * bind plugin: Fix collection of the cached RR sets. The number of RR
772 sets currently in the cache was collected as a counter value, which
773 is nonsense. Thanks to Bruno Prémont for implementing this.
774 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
775 primarily BSDs, don't take it well and crash.
776 * oracle plugin: Portability to 64 bit systems has been improved.
777 * postgresql plugin: The default configuration has been improved.
778 * rrdtool plugin: Fix a possible race condition: If the network plugin

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

820 * curl plugin: This new plugin can be used to read web pages and parse
821 them using the same mechanism that's used in the tail plugin.
822 * dbi plugin: This new plugin allows you to connect to a variety of
823 relational databases and use SQL to gather custom statistics from
824 it. It is similar to the already existing PostgreSQL plugin but uses
825 libdbi to communicate with the database(s).
826 * interface plugin: Use the ignorelist framework when selecting /
827 ignoring interfaces. This allows one to use regular expressions to
828 select interfaces, too.

853 * processes plugin: Stacksize and virtual memory usage statistics have
854 been added. Portability fixes.
855 * rrdcached plugin: This new plugin uses the (still in development)
856 RRD accelerator daemon, rrdcached. This daemon works very similar to
857 the original rrdtool plugin of collectd, but adds some more nice
859 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
862 2009-05-09, Version 4.5.4
863 * Build system, various plugins: Many build fixes for FreeBSD,

878 * rrdtool plugin: Fix a possible race condition: If the network plugin
879 is initialized and dispatches a value before the rrdtool plugin is
880 initialized, the daemon may crash.
881 * memory plugin: Fix a potential problem under Solaris.
883 2009-02-22, Version 4.5.3
884 * build system: The check for libupsclient even when `pkg-config' is

893 code. Thanks to "thated" for reporting this.
895 2009-01-02, Version 4.5.2
896 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
897 file may be in both locations, especially when the database was
898 installed in a non-standard path. Thanks to Dusty Doris for
900 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
901 Solaris, in the configure script automatically.
902 * build system, tcpconns plugin: Check for `kvm_nlist' and
903 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
904 library with similar functions to the BSD variant, but doesn't
905 provide these necessary functions.
906 * collectd.conf(5): Various fixes and clarifications.
907 * collectd: Remove a GNUism (unnamed unions), thus improving
909 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.

912 * filecount plugin: Fix an off-by-one error. This error may cause a
914 * network plugin: Fix the handling of `type' in the network protocol.
915 Due to a programming mistake, only 4 or 8 bytes would be copied to a
916 much larger buffer. This caused the `type' to be transferred much
917 more often than necessary. In some cases, e. g. the `cpu' and
918 `cpufreq' plugins being used at the same time, data may be corrupted
919 in those files. Thanks to Bruno Prémont for debugging and reporting
921 * processes plugin: Fix a possible segmentation fault when specifying
922 invalid configuration options.
923 * unixsock plugin: Make sure the initialization function is run only
924 once. This resolves a file descriptor leak under systems which run
925 the initialization more than once, such as Solaris.
927 2008-10-16, Version 4.5.1
928 * build system: Change `--enable-<plugin>' to abort with an error if
929 dependencies are not met. Thanks to Bruno Prémont for the patch.
930 Also, the poisoning of various string functions has been restricted
932 * collectd: Fix a memory leak in the global value cache. With every
933 *missing* value a couple of bytes would be leaked. Another memory
934 leak in the configuration handling code has been fixed. Thanks to
935 Niraj Tolia for reporting these issues.
936 * collectd: Fix an off-by-one error in the ignorelist functionality.
937 When using regular expressions, the last character would be missing,
938 possibly matching differently from what one would expect.
939 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
941 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
942 Linzberger for reporting the bug.
943 * iptables plugin: Fix an off-by-one error. If a string was just one
944 character too long, it was truncated instead of reporting an error.
945 * network plugin: Fix a memory leak in the configuration handling
946 code. Thanks to Niraj Tolia for reporting this issue.
947 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
948 * postgresql plugin: Don't reopen connection during reinitialization.
949 This fixes a bug under Solaris and potentially other platforms.

951 leaks. Thanks to ``Admin'' for reporting these bugs.
952 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
954 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
955 problems with some `libc's. Thanks to Matthias Lay for reporting the

972 such as temperatures, from sensors connected to the computer via the
974 * perl plugin: Improved synchronized access to internal data structures
975 and fixed a possible dead-lock.
976 * perl plugin: Added the ability to flush certain identifiers and marked
977 plugin_flush_all() and plugin_flush_one() as deprecated in favor of

985 * tcpconns plugin: This plugin has been ported to OpenBSD.
986 * thermal plugin: The new thermal plugin collects system temperatures
987 using Linux ACPI thermal zone data.
989 2009-01-02, Version 4.4.5
990 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
991 file may be in both locations, especially when the database was
992 installed in a non-standard path. Thanks to Dusty Doris for
994 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
995 Solaris, in the configure script automatically.
996 * collectd.conf(5): Various fixes and clarifications.
997 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
998 portability problems, especially for Solaris.
999 * dns plugin: Fix a portability problem with NetBSD.
1000 * network plugin: Fix the handling of `type' in the network protocol.
1001 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1002 much larger buffer. This caused the `type' to be transferred much
1003 more often than necessary. In some cases, e. g. the `cpu' and
1004 `cpufreq' plugins being used at the same time, data may be corrupted
1005 in those files. Thanks to Bruno Prémont for debugging and reporting
1007 * unixsock plugin: Make sure the initialization function is run only
1008 once. This resolves a file descriptor leak under systems which run
1009 the initialization more than once, such as Solaris.
1011 2008-10-16, Version 4.4.4
1012 * build system: Change `--enable-<plugin>' to abort with an error if
1013 dependencies are not met. Thanks to Bruno Prémont for the patch.
1014 Also, the poisoning of various string functions has been restricted
1016 * collectd: Fix a memory leak in the global value cache. With every
1017 *missing* value a couple of bytes would be leaked. Another memory
1018 leak in the configuration handling code has been fixed. Thanks to
1019 Niraj Tolia for reporting these issues.
1020 * collectd: Fix an off-by-one error in the ignorelist functionality.
1021 When using regular expressions, the last character would be missing,
1022 possibly matching differently from what one would expect.
1023 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1025 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1026 Linzberger for reporting the bug.
1027 * network plugin: Fix a memory leak in the configuration handling
1028 code. Thanks to Niraj Tolia for reporting this issue.
1029 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1030 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1031 problems with some `libc's. Thanks to Matthias Lay for reporting the
1034 2008-09-01, Version 4.4.3
1035 * collectd: Fix a memory leak in the threshold checking code.
1036 * memcached plugin: Fix a too short timeout and a related file
1038 * memory plugin: A typo in the libstatgrab code has been fixed.
1039 * snmp plugin: Fix a possible memory leak.
1041 2008-07-15, Version 4.4.2
1042 * build system: Use pkg-config to detect the upsclient library.
1043 * collectd: Try even harder to determine the endianess of the
1044 architecture collectd is being built on.
1045 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1047 * dns plugin: Fix compilation errors with BIND versions 19991001
1049 * network plugin: Bugfix in the init routine: The init function
1050 cleared a buffer regardless of its contents. This could lead to lost
1051 values under Solaris.
1052 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1053 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1055 * wireless plugin: Work around incorrect noise and power values
1056 returned by some broken drivers.
1058 2008-06-03, Version 4.4.1
1059 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1060 to kyrone for reporting this.
1061 * collectd: Fixed min/max output in notifications generated by
1063 * collectd-nagios: Fix the protocol used to communicate with the
1065 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1066 initialization has errors. An issue with Perl 5.10 has been fixed.
1067 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1068 René Rebe and Siegmund Gorr for reporting this.
1070 2008-05-06, Version 4.4.0
1071 * collectd: Internal code cleanups.
1072 * collectd: Added support for a `Flush' command in the unixsock and
1073 exec plugins. This command can be used to force a plugin (or all) to
1074 flush its values to disk.
1075 * collectd: Thresholds can now be configured to apply to one data
1076 source only, making it possible to configure different thresholds
1077 for each data source.
1078 * apache, nginx plugins: Added the possibility to disable host and/or
1080 * ascent plugin: The new ascent plugin reads and parses the statistics
1081 page of an Ascent server.
1082 * cpu plugin: Support for the statgrab library has been added.
1083 * disk plugin: The possibility to ignore certain disks or collect only
1084 specific disks has been added.
1085 * disk plugin: Support for the statgrab library has been added.
1086 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1087 sensor values via IPMI, the intelligent platform management
1089 * iptables plugin: The iptc library that is used by the iptables
1090 plugin has been added to the distribution, because it is not
1091 provided by all distributions and removed from at least one.
1092 * powerdns plugin: The new powerdns plugin reads statistics from an
1093 authoritative or a recursing PowerDNS name server.
1094 * rrdtool plugin: The size of the files generated with the default
1095 configuration has been decreased.
1096 * tail plugin: The new tail plugin can be used to gather statistics by
1097 continuously reading from log files.
1098 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1099 TeamSpeak2 server and collects statistics about the number of users
1100 and number of channels.
1101 * users plugin: Support for the statgrab library has been added.
1102 * vmem plugin: The new vmem plugin collects very detailed statistics
1103 about the virtual memory subsystem of Linux.
1105 2008-08-30, Version 4.3.4
1106 * Build system: Improved detection of and linking with the statgrab
1108 * collectd: Portability fixes, especially to determine endianess more
1110 * Various plugins: Fix format strings.
1111 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1112 again has been applied.
1113 * memcached plugin: Fix a too short timeout and a related file
1115 * memory plugin: A typo in the libstatgrab code has been fixed.
1116 * network plugin: A fix in the initialization function solves problems
1118 * nginx plugin: A thread-unsafe function has been replaced.
1119 * vserver plugin: A thread-unsafe function has been replaced.
1120 * wireless plugin: A work-around for broken wireless drivers has been
1123 2008-04-22, Version 4.3.3
1124 * build system: Improved detection of several libraries, especially if
1125 they are in non-standard paths.
1126 * build system: Portability fixes: Automatically define "_REENTRANT"
1127 if the libc expects it.
1128 * collectd: Error and warning messages have been improved.
1129 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1131 * apache plugin: Allocate new memory when reading a webpage instead of
1132 using a buffer of static size.
1133 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1135 * hddtemp plugin: Error and warning messages have been improved.
1136 * sensors plugin: Fix sensor collection for some chip types.
1138 2008-03-29, Version 4.3.2
1139 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1140 `Persist' threshold options.
1141 * collectd: Fix handling of missing values in the global value cache.
1142 * collectd: Improved error messages when parsing the configuration.
1143 * sensors plugin: Fix temperature collection with libsensors4.
1144 * unixsock plugin: Fix mixed input and output operation on streams.
1145 * wireless plugin: Fix reading noise value.
1147 2008-03-05, Version 4.3.1
1148 * exec plugin: Set supplementary group IDs.
1150 + Use `memcpy' when constructing/parsing a package to avoid
1151 alignment problems on weird architectures, such as Sparc.
1152 + Translate doubles to/from the x86 byte representation to ensure
1153 cross-platform compatibility.
1154 * ping plugin: Correct the handling of the `TTL' setting.
1155 * swap plugin: Reapply a patch for Solaris.
1156 * tcpconns plugin: Portability improvements.
1158 2008-02-18, Version 4.3.0
1159 * collectd: Notifications have been added to the daemon. Notifications
1160 are status messages that may be associated with a data instance.
1161 * collectd: Threshold checking has been added to the daemon. This
1162 means that you can configure threshold values for each data
1163 instance. If this threshold is exceeded a notification will be
1165 * collectd: The new `FQDNLookup' option tells the daemon to use the
1166 full qualified domain name as the hostname, not just the host part
1167 es returned by `gethostname(2)'.
1168 * collectd: Support for more than one `TypesDB' file has been added.
1169 This is useful when one such file is included in a package but one
1170 wants to add custom type definitions.
1171 * collectd: The `Include' config option has been expanded to handle
1172 entire directories and shell wildcards.
1173 * collectdmon: The new `collectdmon' binary detects when collectd
1174 terminates and automatically restarts it again.
1175 * csv plugin: The CSV plugin is now able to store counter values as a
1176 rate, using the `StoreRates' configuration option.
1177 * exec plugin: Handling of notifications has been added and the
1178 ability to pass arguments to the executed programs has been added.
1179 * hddtemp plugin: The new `TranslateDevicename' option lets you
1180 disable the translation from device names to major-minor-numbers.
1181 * logfile plugin: Handling of notifications has been added.
1182 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1183 domain name lookups in this plugin.
1184 * perl plugin: Many internal changes added support for handling multiple
1185 threads making the plugin reasonably usable inside collectd. The API has
1186 been extended to support notifications and export global variables to
1187 Perl plugins; callbacks now have to be identified by name rather than a
1188 pointer to a subroutine. The plugin is no longer experimental.
1189 * uuid plugin: The new UUID plugin sets the hostname to an unique
1190 identifier for this host. This is meant for setups where each client
1191 may migrate to another physical host, possibly going through one or
1192 more name changes in the process. Thanks to Richard Jones from
1193 Red Hat's Emerging Technology group for this plugin.
1194 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1195 CPU, disk and network statistics about guest systems on the same
1196 physical server. Thanks to Richard Jones from Red Hat's Emerging
1197 Technology group for this plugin.
1199 2008-04-22, Version 4.2.7
1200 * build system: Improved detection of several libraries, especially if
1201 they are in non-standard paths.
1202 * build system: Portability fixes: Automatically define "_REENTRANT"
1203 if the libc expects it.
1204 * collectd: Error and warning messages have been improved.
1205 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1207 * apache plugin: Allocate new memory when reading a webpage instead of
1208 using a buffer of static size.
1209 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1211 * hddtemp plugin: Error and warning messages have been improved.
1212 * sensors plugin: Fix sensor collection for some chip types.
1214 2008-03-29, Version 4.2.6
1215 * collectd: Improved error messages when parsing the configuration.
1216 * sensors plugin: Fix temperature collection with libsensors4.
1217 * unixsock plugin: Fix mixed input and output operation on streams.
1218 * wireless plugin: Fix reading noise value.
1220 2008-03-04, Version 4.2.5
1221 * apache plugin: Improved initialization and error messages.
1222 * exec plugin: Set supplementary group IDs.
1224 + Create separate threads for reading from the socket and parsing
1225 and dispatching incoming packets. Versions prior to this may have
1226 problems in high-load situations, where the socket receive buffers
1227 overflows, resulting in gaps in the data.
1228 + Use `memcpy' when constructing/parsing a package to avoid
1229 alignment problems on weird architectures, such as Sparc.
1230 + Translate doubles to/from the x86 byte representation to ensure
1231 cross-platform compatibility.
1232 * ping plugin: Correct the handling of the `TTL' setting.
1233 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1234 * swap plugin: Reapply a patch for Solaris.
1235 * tcpconns plugin: Portability improvements.
1237 2008-01-21, Version 4.2.4
1238 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1239 the permission on the socket as documented in the manpage. Thanks to
1240 Evgeny Chukreev for fixing this issue.
1241 * collectd: The documentation has been improved.
1243 2007-12-28, Version 4.2.3
1244 * sensors plugin: Updated the plugin to build and work with version 3
1245 of the libsensors library.
1247 2007-12-15, Version 4.2.2
1248 * nginx plugin: Incorrect comparison of strings lead to a segfault
1249 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1251 * logfile plugin: The config option `Timestamp' was handled
1252 incorrectly and basically always active. Thanks to Luke Heberling
1255 2007-11-08, Version 4.2.1
1256 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1257 enabled on the host.
1258 * snmp plugin: Fix a memory leak.
1260 2007-10-27, Version 4.2.0
1261 * collectd: The new config option `Include' lets you include other
1262 configfiles and thus split up your config into smaller parts. This
1263 may be especially interesting for the snmp plugin to keep the data
1264 definitions separate from the host definitions.
1265 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1266 (number of connections, octets and packets for each service and
1267 destination). Thanks to Sebastian Harl for this plugin.
1268 * memcached plugin: The new `memcached' plugin connects to a memcached
1269 daemon process and collects statistics of this distributed caching
1270 system. Thanks to Antony Dovgal for contributing this plugin.
1271 * nginx plugin: The new `nginx' plugin reads the status page of an
1272 nginx daemon and saves the handled connections and requests.
1273 * perl plugin: Many changes, including the added `EnableDebugger'
1274 config option which lets you debug your Perl plugins more easily.
1275 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1276 be more thread-safe otherwise by locking calls to the library.
1277 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1278 correct the values returned by SNMP-agents. If a <data> block is
1279 defined as `table' the instance is now optional. The sequence number
1280 is used as the type-instance in this case. The new `InstancePrefix'
1281 option allows to add arbitrary prefixes to the type-instance.
1282 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1283 certain TCP connections and what state they're in. This can be used
1284 to see how many connections your FTP server has to handle or how
1285 many outgoing connections your mailserver has open.
1287 2008-01-11, Version 4.1.6
1288 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1289 the permission on the socket as documented in the manpage. Thanks to
1290 Evgeny Chukreev for fixing this issue.
1291 * collectd: The documentation has been improved.
1293 2007-12-27, Version 4.1.5
1294 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1296 * sensors plugin: Updated the plugin to build and work with version 3
1297 of the libsensors library.
1299 2007-11-08, Version 4.1.4
1300 * Build system: Improve detection of the rrd library, especially if
1301 it's in a non-standard location.
1302 * Build system: A bug when parsing the argument for
1303 `--with-libnetsnmp' has been fixed.
1304 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1305 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1306 a deadlock or delay when shutting down the daemon.
1307 * snmp plugin: Fix a memory leak.
1309 2007-10-24, Version 4.1.3
1310 * collectd: A build issue under Solaris has been resolved by renaming
1312 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1313 be more thread-safe otherwise by locking calls to the library.
1315 2007-09-28, Version 4.1.2
1316 * apcups plugin: Fix reporting of the `load percent' data.
1317 * wireless plugin: Correct the handling of cards returning signal and
1318 noise quality as percentage.
1319 * perl plugin: Fix a possible buffer overflow in get_module_name().
1320 * build system: Further improve the detection of libraries.
1321 * netlink plugin: Build issues under some older versions of the Linux
1322 includes (i. e. Debian Sarge) have been fixed.
1323 * snmp plugin: Fix a potential segfault when a host times out. Add
1324 support for the `timeticks' type.
1326 2007-09-12, Version 4.1.1
1327 * Build system: The detection of `libnetlink' has been improved.
1328 * collectd: The documentation has been fixed in numerous places.
1329 * exec plugin: Setting the group under which to run a program has been
1331 * collectd: The `sstrerror' function was improved to work correctly
1332 with the broken GNU version of `strerror_r'.
1333 * collectd: Write an error message to STDERR when loading of a plugin
1335 * apcups plugin: Fix the `types' used to submit the values: They still
1336 has an `apcups_' prefix which doesn't work anymore.
1337 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1338 whatever the client thinks is `now'..
1340 2007-09-01, Version 4.1.0
1341 * Build system: The build system has been changed to automatically
1342 disable all plugins, which are missing dependencies. The dependency
1343 checking has been removed from the plugins themselves to remove
1345 * Flexible interval: The interval of collected data is now sent along
1346 with the data itself over the network, so that the interval-settings
1347 of server and clients no longer needs to match.
1348 * netlink plugin: The new `netlink' plugin connects to the Linux
1349 kernel using a netlink socket and uses it to query information about
1350 interfaces, qdiscs and classes.
1351 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1352 to not block data collection.
1353 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1354 network devices, such as switches, routers, thermometers, rack
1355 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1357 * unixsock plugin: Added the `LISTVAL' command.
1358 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1359 of music played with xmms.
1361 2007-09-28, Version 4.0.9
1362 * apcups plugin: Fix reporting of the `load percent' data.
1363 * wireless plugin: Correct the handling of cards returning signal and
1364 noise quality as percentage.
1365 * perl plugin: Fix a possible buffer overflow in get_module_name().
1367 2007-09-12, Version 4.0.8
1368 * collectd: The `sstrerror' function was improved to work correctly
1369 with the broken GNU version of `strerror_r'.
1370 * collectd: Write an error message to STDERR when loading of a plugin
1372 * apcups plugin: Fix the `types' used to submit the values: They still
1373 has an `apcups_' prefix which doesn't work anymore.
1374 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1375 whatever the client thinks is `now'..
1377 2007-08-26, Version 4.0.7
1378 * documentation: Some typos have been fixed and some information has
1380 * build system: Many fixes for detecting libraries in unusual places,
1381 such as on RedHat systems. The affected libraries are `libcurl',
1382 `libmysql', and `libupsclient'.
1383 * network plugin: Allow the `Port' option to be specified as a number
1384 (i. e. without quotes).
1385 * nut plugin: A fix allows linking the nut plugin against
1386 libupsclient, version >= 2.2.0.
1387 * processes plugin: Fix a potential segmentation fault.
1389 2007-07-30, Version 4.0.6
1390 * sensors plugin: Fix the ignorelist functionality: Only the `type
1391 instance' was used to match against the list, but the documentation
1392 told otherwise. This release fixes the code, so it complies with the
1394 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1395 configuration messages will end up in the logging facility.
1396 * conrtib/fedora: The contributed specfile for Fedora has been
1399 2007-07-05, Version 4.0.5
1400 * Portability: More fixes for OpenBSD have been included.
1402 2007-06-24, Version 4.0.4

1405 * interface plugin: Fixed the Solaris code.
1406 * load plugin: Fixed the alternative `/proc' Linux code.
1407 * memory plugin: Fixed the Solaris code.
1408 * oconfig: Don't require `-lfl' anymore.
1410 2007-06-19, Version 4.0.3
1411 * cpu plugin: Fix the Darwin / Mac OS X code.
1412 * ping plugin: Use the return value of `getpid', not its address.
1413 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1414 initialized correctly.
1415 * configure: Added `--with-nan-emulation' to aid cross compilation.
1417 2007-06-12, Version 4.0.2
1418 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1419 they're given in numerically form.
1421 2007-06-07, Version 4.0.1
1422 * iptables plugin: A bug in the configuration routine has been fixed.
1423 Setting a comment in the configfile will no longer cause a
1426 2007-06-03, Version 4.0.0
1427 * collectd: The plugin-infrastructure has been changed to allow for
1428 more types of plugins, namely `write' and `log' plugins.
1429 * collectd: The read-function has been changed to read many plugins in
1430 parallel, using threads. Thus, plugins generally need to use
1431 thread-safe functions from now on.
1432 * collectd: The '-t' command line options allows to perform syntax tests
1433 of the configuration file and exit immediately.
1434 * csv plugin: The new `csv' plugin handles output to `comma separated
1436 * rrdtool plugin: The new `rrdtool' plugin handles output to
1437 RRD-files. Data can be cached to combine multiple updates into one
1438 write to increase IO-performance.
1439 * network plugin: The new `network' plugin handles IO via the network.
1440 It implements a different, much more extensible protocol which can
1441 combine many values in one packet, decreasing the number of UDP-
1442 packets being sent. It can read from and send to the network and
1443 with the appropriate configuration even forward packets to other
1445 * unixsock plugin: The new `unixsock' plugin provides an interface to
1446 communicate with the daemon while it is running. Right now the
1447 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1449 * perl plugin: The new `perl' plugin allows you to write extensions
1450 for collectd in the scripting-language Perl.
1451 * logfile plugin: The new `logfile' plugin writes logmessages to files
1452 or STDOUT or STDERR.
1453 * syslog plugin: The new `syslog' plugin sends logmessages to the
1454 system's syslog daemon.
1455 * entropy plugin: The new `entropy' plugin collects the amount of
1456 entropy currently being available to the system.
1457 * exec plugin: The new `exec' plugin forks child processes and reads
1458 back values provided by the forked processes.
1459 * iptables plugin: The new `iptables' plugin reads counters from
1460 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1462 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1463 to Peter Holik for contributing this plugin.
1464 * nut plugin: The new `nut' plugin connects the upsd of the `network
1465 ups tools' and reads information about the connected UPS.
1466 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1467 connections) field was added by Florent Monbillard.
1468 * collectd-nagios: The new `collectd-nagios' binary queries values
1469 from collectd, parses them and exits according to Nagios-standards.
1470 * manpages: The manpages have been improved a lot.
1472 2007-09-28, Version 3.11.7
1473 * wireless plugin: Correct the handling of cards returning signal and
1474 noise quality as percentage.
1476 2007-08-31, Version 3.11.6
1477 * processes plugin: Fix a potential segmentation fault.
1479 2007-05-29, Version 3.11.5
1480 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1481 * ntpd plugin: Fix a potential buffer overflow.
1482 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1483 were accounted as `zombies'.
1485 2007-04-10, Version 3.11.4
1486 * dns plugin: Change the order of includes to make the plugin compile
1489 2007-03-30, Version 3.11.3
1490 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1491 of the unused `COLLECT_KSTAT'.
1493 2007-02-11, Version 3.11.2
1494 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1495 NULL-pointer may have been passed to `printf' which causes a
1496 segfault with some libcs.
1498 2007-02-10, Version 3.11.1
1499 * df plugin: Some wrong defines have been fixed so the plugin works
1500 under Solaris again.
1501 * dns plugin: The usage of a struct has been fixed to work with
1503 * processes plugin: Some missing defines have been added so the plugin
1504 compiles cleanly under FreeBSD and presumably other UNIXes.
1506 2006-12-22, Version 3.11.0
1507 * collectd: The new command line option `-P' makes it easier for
1508 distributors to change the location of PID-files.
1509 * collectd: The daemon shuts down faster now which makes it easier to
1510 write init.d-scripts for it.
1511 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1512 caused problems every now and then.
1513 * df plugin: New config options allow to ignore certain mountpoints,
1514 filesystem types or devices.
1515 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1516 and interprets it. It collects traffic as well as qtype, opcode and
1518 * email plugin: Sebastian Harl has contributed this plugin which
1519 counts received mails in categories (e. g. ham, spam, virus), spam
1520 score (as given by SpamAssassin) and check types.
1521 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1522 uses `mbmon' to gather information from sensors on the motherboard.
1523 * processes plugin: Collect detailed statistics for configured
1524 processes, that's process and thread count, CPU usage, resident
1525 segment size and pagefaults.
1526 * multimeter plugin: Peter Holik contributed a new plugin which
1527 queries multimeters.
1528 * sensors plugin: Lubos Stanek has put much effort into improving this
1529 plugin, including `extended naming', collection of voltage values
1530 and the possibility to ignore certain values.
1532 2006-12-21, Version 3.10.4
1533 * Max Kellermann has identified a bug in the server routine: When
1534 opening a socket fails the daemon will (re)try opening the socket in
1535 an endless loop, ultimately leading to a `EMFILE' error.
1537 2006-11-04, Version 3.10.3
1538 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1539 ntpd's reply was sent in more than one packet, the buffer size was
1540 calculated incorrectly, resulting in the reading of uninitialized or
1543 2006-11-01, Version 3.10.2
1544 * The sample config file has been improved.
1545 * Errors in the manpages have been corrected.
1546 * The ping-plugin now adds hosts during initialization, not during
1547 startup. This speeds up startup when no network connectivity is
1548 available. Also, the hosts are being added later when the network is
1550 * Improved BSD-support for the df-plugin.
1551 * Fixed syntax errors in the swap-plugin for Mac OS X.
1552 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1554 * Don't disable the mysql-plugin if connecting to the database fails
1555 during initialization. Instead, try again in increasing intervals.
1557 2006-07-19, Version 3.10.1
1558 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1559 the apcups cannot be reached, unconnected sockets will pile up and
1560 eventually lead to `Too many open files' errors.
1562 2006-07-09, Version 3.10.0
1563 * The `disk' plugin has been ported to Darwin.
1564 * The `battery' plugin should work on many Apple computers now.
1565 * The `traffic' plugin can now ignore certain interfaces. Also,
1566 statistics for sent/received packets and errors have been added.
1567 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1568 to Anthony Gialluca for contributing this plugin and providing me
1569 with a test environment :)
1570 * A plugin for monitoring an NTP instance and the local clock drift
1573 2006-06-25, Version 3.9.4
1574 * The Solaris code in the `swap' plugin has been changed to reflect
1575 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1577 * The debugging system has been fixed to work with the Sun libc.
1578 * When built without librrd the variable `operating_mode' could be
1579 uninitialized. Thanks to David Elliot for reporting the bug.
1581 2006-06-01, Version 3.9.3
1582 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1583 operating systems also profit from the changes, but I wasn't able to
1585 * Changed the build system to find the netinet-includes under FreeBSD
1586 and therefore successfully build the `liboping' library there.
1588 2006-05-09, Version 3.9.2
1589 * Applied a patch to the `liboping' library. Due to a bug in the
1590 sequence checking the `ping' plugin stopped working after
1591 approximately 7.6 days.
1593 2006-05-09, Version 3.8.5
1594 * Applied a patch to the `liboping' library. Due to a bug in the
1595 sequence checking the `ping' plugin stopped working after
1596 approximately 7.6 days.
1598 2006-04-21, Version 3.9.1
1599 * Build issues with Solaris and possible other architectures have been
1601 * Problems when building the `apache'-plugin without `libcurl' have
1603 * A bug in the `ping' plugin has been fixed. Sorry folks.
1605 2006-04-02, Version 3.9.0
1606 * A plugin to monitor the Apache webserver has been added.
1607 <http://httpd.apache.org/>
1608 * A plugin to collect statistics about virtual servers using VServer.
1609 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1611 * A plugin for wireless LAN cards has been added. It monitors signal
1612 strength, link quality and noise ratio..
1613 * A plugin for Apple hardware sensors has been added.
1614 * An option to compile collectd with different `step' and `heartbeat'
1615 settings has been added. The size of RRAs is no longer static but
1616 calculated based on the settings for `step' and `width'.
1617 * The `ping' plugin can now be configured to use a certain TTL.
1618 * A plugin to monitor the hardware sensors of Apple computers has been
1620 * The plugins `cpu', `memory', `processes' and `traffic' have been
1621 ported to Mach/Darwin (Mac OS X).
1622 * The `log mode' has been contributed by Christophe Kalt. It writes
1623 the data into text files rather than RRD files.
1625 2006-04-09, Version 3.8.4
1626 * Applied patch by Vincent Stehlé which improves the disk-name
1627 resolution in the `hddtemp' plugin for Linux systems.
1629 2006-04-02, Version 3.8.3
1630 * Applied a patch by James Byers: The MySQL plugin was not working
1631 with MySQL 5.0.2 or later.
1633 2006-03-14, Version 3.8.2
1634 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1635 the GNU libc, because it points to `/etc/fstab' rather than
1638 2006-03-13, Version 3.8.1
1639 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1640 * Fixes in the debian `postinst' and `init.d' scripts.
1642 2006-03-09, Version 3.8.0
1643 * The `ping' plugin no longer uses `libping' but a self written
1644 library named `liboping'. With this library it's possible to ping
1645 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1647 2006-02-18, Version 3.7.2
1648 * A simple bug in the `battery' plugin has been fixed. It should now
1649 work with ACPI based batteries as well. Thanks to Sebastian for
1651 * Fixing a bug that prevented collectd to be built without librrd.
1652 Thanks to Werner Heuser for reporting it.
1654 2006-02-04, Version 3.7.1
1655 * The new network code has been improved to build with older versions
1657 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1658 to Tommie Gannert for this patch.
1660 2006-01-30, Version 3.7.0
1661 * The `battery' plugin has been added. It collects information about
1663 * The MySQL plugin has been improved: It now writes two more RRD
1664 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1665 * The `cpufreq' plugin now reads another file since the file it did
1666 read so far causes much overhead in the kernel. Also, you need root
1667 to read the old file, but not to read the new one.
1668 * The `hddtemp' plugin can now be configured to connect to another
1669 address and/or port than localhost.
1670 * The `df' plugin now prefers `statvfs' over `statfs'.
1671 * The network code has been rewritten. collectd now supports unicast
1672 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1673 be set in the configfile.
1675 2006-01-24, Version 3.6.2
1676 * Due to a bug in the configfile handling collectd wouldn't start in
1677 client mode. This released fixes this.
1679 2006-01-20, Version 3.6.1
1680 * Due to a bug in `configure.in' all modules and the binary were
1681 linked against `libmysqlclient'. This issue is solved by this
1684 2006-01-17, Version 3.6.0
1685 * A config file has been added. This allows for loading only specific
1687 * A `df' plugin has been added.
1688 * A `mysql' plugin has been added.
1689 * The `ping' plugin doesn't entirely give up hope when a socket error
1690 occurred, but will back of and increase the intervals between tries.
1692 2006-01-21, Version 3.5.2
1693 * Fixed yet another bug in the signal handling.. Stupid typo..
1694 * Improved the ping plugin to not give up on socket errors (backport
1697 2005-12-18, Version 3.5.1
1698 * The PID-file is now deleted correctly when shutting down the daemon.
1699 * SIGINT and SIGTERM are now handled correctly.
1701 2005-12-16, Version 3.5.0 (Revision 326)
1702 * A bug in the `load' module under Solaris has been fixed.
1703 * The `users' module has been contributed by Sebastian Harl. It counts
1704 currently logged in users.
1705 * The CPU module now works under FreeBSD without the use of
1706 `libstatgrab', however SMP support is missing.
1707 * The default directories for the RRD files and the PID file now
1708 depend on the compile time setting of `localstatedir'.
1710 2005-11-15, Version 3.4.0 (Revision 236)
1711 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1712 from gentoo's bugzilla for writing the patch.
1713 * The build dependency for librrd has been removed. Binaries built
1714 without librrd are client-only and will multicast their value as
1715 with the `-c' argument.
1716 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1717 * The newly introduced `-f' switch prevents daemon initialization
1718 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1719 Barcellos for this patch.
1721 2005-11-04, Version 3.3.0 (Revision 216)
1722 * New modules have been added:
1723 - `serial', for monitoring traffic on the serial interfaces
1724 - `nfs', for graphing NFS procedure calls
1725 - `tape', traffic from/to tape devices
1726 * The memory.rrd now accepts more than 4Gig of memory.
1728 2005-10-26, Version 3.2.0 (Revision 200)
1729 * Support for graphing the processes has been added (thanks to Lyonel
1731 * If reading from hddtemp fails collectd will increase the time
1732 between polls up to one day.
1733 * The init.d files have been improved.
1734 * Problems with the spec file have been fixed.
1736 2005-10-16, Version 3.1.0 (Revision 194)
1737 * Added the `setsid' syscall to the startup code.
1738 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1740 2005-09-30, Version 3.0.0 (Revision 184)
1741 * The ability to send/receive data to/from the network (think
1742 multicast) has been added.
1743 * Modules have been split up into shared libraries can be loaded at
1744 runtime. The biggest advantage is that the core program doesn't need
1745 to be linked against an external library.
1746 * A patch by George Kargiotakis has been applied: It fixes the sensors
1747 behaviour then more than one sensor is being queried.
1749 2005-09-16, Version 2.1.0 (Revision 172)
1750 * A module for swap statistics has been added.
1752 2005-09-09, Version 2.0.0 (Revision 135)
1753 * Filenames can no longer be configured at program startup. The only
1754 options as of this version are the directory and ping hosts.
1755 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1756 Soft-IRQ statistics are added to `System'.
1757 * Diskstats now collect read and write bytes, not sectors.
1758 * Ping statistics can now be collected for more than one host. There
1759 is no default any more: If no host is given no host will be pinged.
1760 * A self-written patch for libping has been applied so it builds
1763 2005-09-01, Version 1.8.1 (Revision 123)
1764 * Much improved configure-script: libraries and features may now be
1766 * More detailed warnings/error messages when RRD update fails.
1768 2005-08-29, Version 1.8.0:
1769 * Support for collecting disk statistics under Solaris.
1771 2005-08-25, Version 1.7.0:
1772 * Support for libstatgrab[1] for load, memory usage and network
1773 traffic. CPU- and disk-usage are not (yet) supported, since
1774 libstatgrab returns insufficient information. I will contact the
1776 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1777 aren't necessarily counted linear which is now handled correctly.
1778 [1]: http://www.i-scream.org/libstatgrab/
1780 2005-08-21, Version 1.6.0:
1781 * Basic support for Solaris: System load and cpu-usage can be
1782 collected under Solaris, too. Other stats will follow later.
1783 * Many fixes in the autoconf-script
1784 * Collection/Museum scripts have been added under contrib/museum
1785 * collectd may now be started in unprivileged mode, though ping
1786 statistics will not work.
1788 2005-07-17, Version 1.5.1:
1789 * Diskstats-RRDs now use major/minor for naming. Some systems have
1790 weird strings as disk-names..
1792 2005-07-17, Version 1.5:
1793 * A new module, diskstats, has been added. It collects information
1794 about the disks and partitions.
1796 2005-07-11, Version 1.4.2:
1797 * The meminfo module has been changed to work with more platforms
1798 and/or kernel versions.
1800 2005-07-10, Version 1.4.1: Correct traffic stats
1801 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1802 forgot to correct when I changed that module.
1804 2005-07-09, Version 1.4: More traffic stats
1805 * Traffic is now collected for all interfaces that can be found
1806 * Temperature-statistics are read from lm-sensors if available
1808 2005-07-08, Version 1.3: CPU stats
1809 * Collecting CPU statistics now
1811 2005-07-12, Version 1.2: Using syslog
1812 * collectd is now using the syslog facility to report errors, warnings
1814 * The default directory is now /var/db/collectd
1816 2005-07-10, Version 1.1: Minor changes
1817 * Nothing really useful to say ;)
1819 2005-07-09, Version 1.0: Initial Version
1820 * The following modules are provided:
