986 * collectd: Added the `filter chain' infrastructure, which allows the
987 user to use `matches' and `targets' to control value processing.
988 * collectd: The new `-T' command line argument allows more in-depth
989 testing of a configuration. Thanks to Doug MacEachern for the patch.
990 * collectd-nagios: The Nagios integration command has been updated to
991 use libcollectdclient. The `percentage' aggregation function has
992 been added. Thanks to Fabian Linzberger for the patch.
993 * libcollectdclient: A library which abstracts communication with the
994 unixsock plugin for clients has been added.
995 * regex match: Match values by their identifies using regular
997 * timediff match: Match for values with an invalid timestamp.
998 * value match: Select values by their data sources' values.
999 * notification target: Create and dispatch a notification.
1000 * replace target: Replace parts of an identifier using regular
1002 * set target: Set (overwrite) entire parts of an identifier.
1003 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1004 statistics, allowing very detailed name server statistics. Thanks to
1005 Bruno Prémont for this plugin.
1006 * cpu plugin: Report `interrupt' separately when using
1007 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1008 example for native OpenBSD support, has been added. Thanks to Simon
1009 Kuhnle for the patch.
1010 * csv plugin: Make it possible to write values to STDOUT instead of
1011 files. This is meant for testing purposes mostly. The output written
1012 to STDOUT is compatible with the exec plugin. Thanks to Doug
1013 MacEachern for the patch.
1014 * curl plugin: This new plugin can be used to read web pages and parse
1015 them using the same mechanism that's used in the tail plugin.
1016 * dbi plugin: This new plugin allows you to connect to a variety of
1017 relational databases and use SQL to gather custom statistics from
1018 it. It is similar to the already existing PostgreSQL plugin but uses
1019 libdbi to communicate with the database(s).
1020 * interface plugin: Use the ignorelist framework when selecting /
1021 ignoring interfaces. This allows one to use regular expressions to
1022 select interfaces, too.
1023 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1024 Thanks to Bruno Prémont for this patch.
1025 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1027 * mysql plugin: Allow connecting to a database via the UNIX domain
1028 socket, too. Thanks to Mirko Buffoni for the patch.
1029 * network plugin: Further performance improvements for the receive
1030 code. This hopefully will help very large setups.
1031 * openvpn plugin: This new plugin collects statistics provided by the
1032 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1033 * oracle plugin: This new plugin allows you to connect to an Oracle
1034 database and use SQL to gather custom statistics from it. It is
1035 similar to the already existing PostgreSQL plugin.
1036 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1038 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1039 * perl plugin: Added support for `notification meta data'.
1040 * perl plugin: Added support for the `filter chain' infrastructure by
1041 allowing plugins to register `matches' and `targets'.
1042 * postgresql plugin: The preferred configuration syntax has been
1043 updated to be in line with the syntax used by the new dbi and oracle
1044 plugins. The compatibility code for the old syntax is present.
1045 Support for the new `Result' blocks and the interval parameter has
1047 * processes plugin: Stacksize and virtual memory usage statistics have
1048 been added. Portability fixes.
1049 * rrdcached plugin: This new plugin uses the (still in development)
1050 RRD accelerator daemon, rrdcached. This daemon works very similar to
1051 the original rrdtool plugin of collectd, but adds some more nice
1053 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1056 2009-05-09, Version 4.5.4
1057 * Build system, various plugins: Many build fixes for FreeBSD,
1058 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1059 for many fixes and providing a build system for many platforms,
1060 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1061 providing an OpenBSD system.
1062 * collectd: Fix a potential race condition when creating directories.
1063 * battery plugin: Don't complain about a missing directory every
1065 * dns plugin: Slight portability fixes.
1066 * exec plugin: Allow executed programs to close STDERR. Thanks to
1067 Thorsten von Eicken for reporting this problem.
1068 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1069 Tomasz Pala for the patch.
1070 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1072 * rrdtool plugin: Fix a possible race condition: If the network plugin
1073 is initialized and dispatches a value before the rrdtool plugin is
1074 initialized, the daemon may crash.
1075 * memory plugin: Fix a potential problem under Solaris.
1077 2009-02-22, Version 4.5.3
1078 * build system: The check for libupsclient even when `pkg-config' is
1080 * collectd: Fix error handling in the global cache.
1081 * Collectd::Unixsock: Error handling has been improved.
1082 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1084 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1085 faults. Thanks to Peter Holik for his patch.
1086 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1087 code. Thanks to "thated" for reporting this.
1089 2009-01-02, Version 4.5.2
1090 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1091 file may be in both locations, especially when the database was
1092 installed in a non-standard path. Thanks to Dusty Doris for
1094 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1095 Solaris, in the configure script automatically.
1096 * build system, tcpconns plugin: Check for `kvm_nlist' and
1097 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1098 library with similar functions to the BSD variant, but doesn't
1099 provide these necessary functions.
1100 * collectd.conf(5): Various fixes and clarifications.
1101 * collectd: Remove a GNUism (unnamed unions), thus improving
1103 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1104 This solves portability problems, especially for Solaris.
1105 * dns plugin: Fix a portability problem with NetBSD.
1106 * filecount plugin: Fix an off-by-one error. This error may cause a
1108 * network plugin: Fix the handling of `type' in the network protocol.
1109 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1110 much larger buffer. This caused the `type' to be transferred much
1111 more often than necessary. In some cases, e. g. the `cpu' and
1112 `cpufreq' plugins being used at the same time, data may be corrupted
1113 in those files. Thanks to Bruno Prémont for debugging and reporting
1115 * processes plugin: Fix a possible segmentation fault when specifying
1116 invalid configuration options.
1117 * unixsock plugin: Make sure the initialization function is run only
1118 once. This resolves a file descriptor leak under systems which run
1119 the initialization more than once, such as Solaris.
1121 2008-10-16, Version 4.5.1
1122 * build system: Change `--enable-<plugin>' to abort with an error if
1123 dependencies are not met. Thanks to Bruno Prémont for the patch.
1124 Also, the poisoning of various string functions has been restricted
1126 * collectd: Fix a memory leak in the global value cache. With every
1127 *missing* value a couple of bytes would be leaked. Another memory
1128 leak in the configuration handling code has been fixed. Thanks to
1129 Niraj Tolia for reporting these issues.
1130 * collectd: Fix an off-by-one error in the ignorelist functionality.
1131 When using regular expressions, the last character would be missing,
1132 possibly matching differently from what one would expect.
1133 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1135 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1136 Linzberger for reporting the bug.
1137 * iptables plugin: Fix an off-by-one error. If a string was just one
1138 character too long, it was truncated instead of reporting an error.
1139 * network plugin: Fix a memory leak in the configuration handling
1140 code. Thanks to Niraj Tolia for reporting this issue.
1141 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1142 * postgresql plugin: Don't reopen connection during reinitialization.
1143 This fixes a bug under Solaris and potentially other platforms.
1144 Missing calls to `PQclear' have been added, too. This fixes memory
1145 leaks. Thanks to ``Admin'' for reporting these bugs.
1146 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1148 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1149 problems with some `libc's. Thanks to Matthias Lay for reporting the
1152 2008-09-04, Version 4.5.0
1153 * collectd: Added the ability to flush certain identifiers.
1154 * collectd: The concept of `notification meta data' has been
1156 * filecount plugin: The new filecount plugin counts the number of
1157 files in a directory and its subdirectories.
1158 * ipmi plugin: Sensor names have been changed to ensure unique names.
1159 Notifications upon added and removed sensors can now be generated.
1160 * notify_desktop plugin: This new plugin sends notifications to the
1161 X desktop using the structure defined in the `Desktop Notification
1163 * notify_email plugin: This new plugin sends out notifications via
1164 email, using the `esmtp' library.
1165 * onewire plugin: The new experimental(!) onewire plugin reads values,
1166 such as temperatures, from sensors connected to the computer via the
1168 * perl plugin: Improved synchronized access to internal data structures
1169 and fixed a possible dead-lock.
1170 * perl plugin: Added the ability to flush certain identifiers and marked
1171 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1173 * perl plugin: Added the ability to configure Perl plugins.
1174 * postgresql plugin: The new postgresql plugin collects statistics
1175 about or from a PostgreSQL database.
1176 * processes plugin: The `ProcessMatch' option has been added.
1177 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1179 * tcpconns plugin: This plugin has been ported to OpenBSD.
1180 * thermal plugin: The new thermal plugin collects system temperatures
1181 using Linux ACPI thermal zone data.
1183 2009-01-02, Version 4.4.5
1184 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1185 file may be in both locations, especially when the database was
1186 installed in a non-standard path. Thanks to Dusty Doris for
1188 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1189 Solaris, in the configure script automatically.
1190 * collectd.conf(5): Various fixes and clarifications.
1191 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1192 portability problems, especially for Solaris.
1193 * dns plugin: Fix a portability problem with NetBSD.
1194 * network plugin: Fix the handling of `type' in the network protocol.
1195 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1196 much larger buffer. This caused the `type' to be transferred much
1197 more often than necessary. In some cases, e. g. the `cpu' and
1198 `cpufreq' plugins being used at the same time, data may be corrupted
1199 in those files. Thanks to Bruno Prémont for debugging and reporting
1201 * unixsock plugin: Make sure the initialization function is run only
1202 once. This resolves a file descriptor leak under systems which run
1203 the initialization more than once, such as Solaris.
1205 2008-10-16, Version 4.4.4
1206 * build system: Change `--enable-<plugin>' to abort with an error if
1207 dependencies are not met. Thanks to Bruno Prémont for the patch.
1208 Also, the poisoning of various string functions has been restricted
1210 * collectd: Fix a memory leak in the global value cache. With every
1211 *missing* value a couple of bytes would be leaked. Another memory
1212 leak in the configuration handling code has been fixed. Thanks to
1213 Niraj Tolia for reporting these issues.
1214 * collectd: Fix an off-by-one error in the ignorelist functionality.
1215 When using regular expressions, the last character would be missing,
1216 possibly matching differently from what one would expect.
1217 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1219 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1220 Linzberger for reporting the bug.
1221 * network plugin: Fix a memory leak in the configuration handling
1222 code. Thanks to Niraj Tolia for reporting this issue.
1223 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1224 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1225 problems with some `libc's. Thanks to Matthias Lay for reporting the
1228 2008-09-01, Version 4.4.3
1229 * collectd: Fix a memory leak in the threshold checking code.
1230 * memcached plugin: Fix a too short timeout and a related file
1232 * memory plugin: A typo in the libstatgrab code has been fixed.
1233 * snmp plugin: Fix a possible memory leak.
1235 2008-07-15, Version 4.4.2
1236 * build system: Use pkg-config to detect the upsclient library.
1237 * collectd: Try even harder to determine the endianess of the
1238 architecture collectd is being built on.
1239 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1241 * dns plugin: Fix compilation errors with BIND versions 19991001
1243 * network plugin: Bugfix in the init routine: The init function
1244 cleared a buffer regardless of its contents. This could lead to lost
1245 values under Solaris.
1246 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1247 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1249 * wireless plugin: Work around incorrect noise and power values
1250 returned by some broken drivers.
1252 2008-06-03, Version 4.4.1
1253 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1254 to kyrone for reporting this.
1255 * collectd: Fixed min/max output in notifications generated by
1257 * collectd-nagios: Fix the protocol used to communicate with the
1259 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1260 initialization has errors. An issue with Perl 5.10 has been fixed.
1261 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1262 René Rebe and Siegmund Gorr for reporting this.
1264 2008-05-06, Version 4.4.0
1265 * collectd: Internal code cleanups.
1266 * collectd: Added support for a `Flush' command in the unixsock and
1267 exec plugins. This command can be used to force a plugin (or all) to
1268 flush its values to disk.
1269 * collectd: Thresholds can now be configured to apply to one data
1270 source only, making it possible to configure different thresholds
1271 for each data source.
1272 * apache, nginx plugins: Added the possibility to disable host and/or
1274 * ascent plugin: The new ascent plugin reads and parses the statistics
1275 page of an Ascent server.
1276 * cpu plugin: Support for the statgrab library has been added.
1277 * disk plugin: The possibility to ignore certain disks or collect only
1278 specific disks has been added.
1279 * disk plugin: Support for the statgrab library has been added.
1280 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1281 sensor values via IPMI, the intelligent platform management
1283 * iptables plugin: The iptc library that is used by the iptables
1284 plugin has been added to the distribution, because it is not
1285 provided by all distributions and removed from at least one.
1286 * powerdns plugin: The new powerdns plugin reads statistics from an
1287 authoritative or a recursing PowerDNS name server.
1288 * rrdtool plugin: The size of the files generated with the default
1289 configuration has been decreased.
1290 * tail plugin: The new tail plugin can be used to gather statistics by
1291 continuously reading from log files.
1292 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1293 TeamSpeak2 server and collects statistics about the number of users
1294 and number of channels.
1295 * users plugin: Support for the statgrab library has been added.
1296 * vmem plugin: The new vmem plugin collects very detailed statistics
1297 about the virtual memory subsystem of Linux.
1299 2008-08-30, Version 4.3.4
1300 * Build system: Improved detection of and linking with the statgrab
1302 * collectd: Portability fixes, especially to determine endianess more
1304 * Various plugins: Fix format strings.
1305 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1306 again has been applied.
1307 * memcached plugin: Fix a too short timeout and a related file
1309 * memory plugin: A typo in the libstatgrab code has been fixed.
1310 * network plugin: A fix in the initialization function solves problems

1318 * build system: Improved detection of several libraries, especially if
1319 they are in non-standard paths.
1320 * build system: Portability fixes: Automatically define "_REENTRANT"
1321 if the libc expects it.
1322 * collectd: Error and warning messages have been improved.
1323 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1325 * apache plugin: Allocate new memory when reading a webpage instead of
1326 using a buffer of static size.
1327 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1329 * hddtemp plugin: Error and warning messages have been improved.
1330 * sensors plugin: Fix sensor collection for some chip types.
1332 2008-03-29, Version 4.3.2
1333 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1334 `Persist' threshold options.
1335 * collectd: Fix handling of missing values in the global value cache.
1336 * collectd: Improved error messages when parsing the configuration.
1337 * sensors plugin: Fix temperature collection with libsensors4.
1338 * unixsock plugin: Fix mixed input and output operation on streams.
1339 * wireless plugin: Fix reading noise value.
1341 2008-03-05, Version 4.3.1
1342 * exec plugin: Set supplementary group IDs.
1344 + Use `memcpy' when constructing/parsing a package to avoid
1345 alignment problems on weird architectures, such as Sparc.
1346 + Translate doubles to/from the x86 byte representation to ensure
1347 cross-platform compatibility.
1348 * ping plugin: Correct the handling of the `TTL' setting.
1349 * swap plugin: Reapply a patch for Solaris.
1350 * tcpconns plugin: Portability improvements.
1352 2008-02-18, Version 4.3.0
1353 * collectd: Notifications have been added to the daemon. Notifications
1354 are status messages that may be associated with a data instance.
1355 * collectd: Threshold checking has been added to the daemon. This
1356 means that you can configure threshold values for each data
1357 instance. If this threshold is exceeded a notification will be
1359 * collectd: The new `FQDNLookup' option tells the daemon to use the
1360 full qualified domain name as the hostname, not just the host part
1361 es returned by `gethostname(2)'.
1362 * collectd: Support for more than one `TypesDB' file has been added.
1363 This is useful when one such file is included in a package but one
1364 wants to add custom type definitions.
1365 * collectd: The `Include' config option has been expanded to handle
1366 entire directories and shell wildcards.
1367 * collectdmon: The new `collectdmon' binary detects when collectd
1368 terminates and automatically restarts it again.
1369 * csv plugin: The CSV plugin is now able to store counter values as a
1370 rate, using the `StoreRates' configuration option.
1371 * exec plugin: Handling of notifications has been added and the
1372 ability to pass arguments to the executed programs has been added.
1373 * hddtemp plugin: The new `TranslateDevicename' option lets you
1374 disable the translation from device names to major-minor-numbers.
1375 * logfile plugin: Handling of notifications has been added.
1376 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1377 domain name lookups in this plugin.
1378 * perl plugin: Many internal changes added support for handling multiple
1379 threads making the plugin reasonably usable inside collectd. The API has
1380 been extended to support notifications and export global variables to
1381 Perl plugins; callbacks now have to be identified by name rather than a
1382 pointer to a subroutine. The plugin is no longer experimental.
1383 * uuid plugin: The new UUID plugin sets the hostname to an unique
1384 identifier for this host. This is meant for setups where each client
1385 may migrate to another physical host, possibly going through one or
1386 more name changes in the process. Thanks to Richard Jones from
1387 Red Hat's Emerging Technology group for this plugin.
1388 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1389 CPU, disk and network statistics about guest systems on the same
1390 physical server. Thanks to Richard Jones from Red Hat's Emerging
1391 Technology group for this plugin.
1393 2008-04-22, Version 4.2.7
1394 * build system: Improved detection of several libraries, especially if
1395 they are in non-standard paths.
1396 * build system: Portability fixes: Automatically define "_REENTRANT"
1397 if the libc expects it.
1398 * collectd: Error and warning messages have been improved.
1399 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1401 * apache plugin: Allocate new memory when reading a webpage instead of
1402 using a buffer of static size.
1403 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1405 * hddtemp plugin: Error and warning messages have been improved.
1406 * sensors plugin: Fix sensor collection for some chip types.
1408 2008-03-29, Version 4.2.6
1409 * collectd: Improved error messages when parsing the configuration.
1410 * sensors plugin: Fix temperature collection with libsensors4.
1411 * unixsock plugin: Fix mixed input and output operation on streams.
1412 * wireless plugin: Fix reading noise value.
1414 2008-03-04, Version 4.2.5
1415 * apache plugin: Improved initialization and error messages.
1416 * exec plugin: Set supplementary group IDs.
1418 + Create separate threads for reading from the socket and parsing
1419 and dispatching incoming packets. Versions prior to this may have
1420 problems in high-load situations, where the socket receive buffers
1421 overflows, resulting in gaps in the data.
1422 + Use `memcpy' when constructing/parsing a package to avoid
1423 alignment problems on weird architectures, such as Sparc.
1424 + Translate doubles to/from the x86 byte representation to ensure
1425 cross-platform compatibility.
1426 * ping plugin: Correct the handling of the `TTL' setting.
1427 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1428 * swap plugin: Reapply a patch for Solaris.
1429 * tcpconns plugin: Portability improvements.
1431 2008-01-21, Version 4.2.4
1432 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1433 the permission on the socket as documented in the manpage. Thanks to
1434 Evgeny Chukreev for fixing this issue.
1435 * collectd: The documentation has been improved.
1437 2007-12-28, Version 4.2.3
1438 * sensors plugin: Updated the plugin to build and work with version 3
1439 of the libsensors library.
1441 2007-12-15, Version 4.2.2
1442 * nginx plugin: Incorrect comparison of strings lead to a segfault
1443 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1445 * logfile plugin: The config option `Timestamp' was handled
1446 incorrectly and basically always active. Thanks to Luke Heberling
1449 2007-11-08, Version 4.2.1
1450 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1451 enabled on the host.
1452 * snmp plugin: Fix a memory leak.
1454 2007-10-27, Version 4.2.0
1455 * collectd: The new config option `Include' lets you include other
1456 configfiles and thus split up your config into smaller parts. This
1457 may be especially interesting for the snmp plugin to keep the data
1458 definitions separate from the host definitions.
1459 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1460 (number of connections, octets and packets for each service and
1461 destination). Thanks to Sebastian Harl for this plugin.
1462 * memcached plugin: The new `memcached' plugin connects to a memcached
1463 daemon process and collects statistics of this distributed caching
1464 system. Thanks to Antony Dovgal for contributing this plugin.
1465 * nginx plugin: The new `nginx' plugin reads the status page of an
1466 nginx daemon and saves the handled connections and requests.
1467 * perl plugin: Many changes, including the added `EnableDebugger'
1468 config option which lets you debug your Perl plugins more easily.
1469 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1470 be more thread-safe otherwise by locking calls to the library.
1471 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1472 correct the values returned by SNMP-agents. If a <data> block is
1473 defined as `table' the instance is now optional. The sequence number
1474 is used as the type-instance in this case. The new `InstancePrefix'
1475 option allows to add arbitrary prefixes to the type-instance.
1476 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1477 certain TCP connections and what state they're in. This can be used
1478 to see how many connections your FTP server has to handle or how
1479 many outgoing connections your mailserver has open.
1481 2008-01-11, Version 4.1.6
1482 * unixsock plugin: A bug in the unixsock plugin caused it not to set

1500 a deadlock or delay when shutting down the daemon.
1501 * snmp plugin: Fix a memory leak.
1503 2007-10-24, Version 4.1.3
1504 * collectd: A build issue under Solaris has been resolved by renaming
1506 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1507 be more thread-safe otherwise by locking calls to the library.
1509 2007-09-28, Version 4.1.2
1510 * apcups plugin: Fix reporting of the `load percent' data.
1511 * wireless plugin: Correct the handling of cards returning signal and
1512 noise quality as percentage.
1513 * perl plugin: Fix a possible buffer overflow in get_module_name().

1522 * collectd: The documentation has been fixed in numerous places.
1523 * exec plugin: Setting the group under which to run a program has been
1525 * collectd: The `sstrerror' function was improved to work correctly
1526 with the broken GNU version of `strerror_r'.
1527 * collectd: Write an error message to STDERR when loading of a plugin
1529 * apcups plugin: Fix the `types' used to submit the values: They still
1530 has an `apcups_' prefix which doesn't work anymore.
1531 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1532 whatever the client thinks is `now'..
1534 2007-09-01, Version 4.1.0
1535 * Build system: The build system has been changed to automatically
1536 disable all plugins, which are missing dependencies. The dependency
1537 checking has been removed from the plugins themselves to remove
1539 * Flexible interval: The interval of collected data is now sent along
1540 with the data itself over the network, so that the interval-settings
1541 of server and clients no longer needs to match.
1542 * netlink plugin: The new `netlink' plugin connects to the Linux
1543 kernel using a netlink socket and uses it to query information about
1544 interfaces, qdiscs and classes.
1545 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1546 to not block data collection.
1547 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1548 network devices, such as switches, routers, thermometers, rack
1549 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1551 * unixsock plugin: Added the `LISTVAL' command.
1552 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1553 of music played with xmms.
1555 2007-09-28, Version 4.0.9
1556 * apcups plugin: Fix reporting of the `load percent' data.
1557 * wireless plugin: Correct the handling of cards returning signal and
1558 noise quality as percentage.
1559 * perl plugin: Fix a possible buffer overflow in get_module_name().
1561 2007-09-12, Version 4.0.8
1562 * collectd: The `sstrerror' function was improved to work correctly
1563 with the broken GNU version of `strerror_r'.
1564 * collectd: Write an error message to STDERR when loading of a plugin
1566 * apcups plugin: Fix the `types' used to submit the values: They still
1567 has an `apcups_' prefix which doesn't work anymore.
1568 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1569 whatever the client thinks is `now'..
1571 2007-08-26, Version 4.0.7
1572 * documentation: Some typos have been fixed and some information has
1574 * build system: Many fixes for detecting libraries in unusual places,
1575 such as on RedHat systems. The affected libraries are `libcurl',
1576 `libmysql', and `libupsclient'.
1577 * network plugin: Allow the `Port' option to be specified as a number
1578 (i. e. without quotes).
1579 * nut plugin: A fix allows linking the nut plugin against
1580 libupsclient, version >= 2.2.0.
1581 * processes plugin: Fix a potential segmentation fault.
1583 2007-07-30, Version 4.0.6
1584 * sensors plugin: Fix the ignorelist functionality: Only the `type
1585 instance' was used to match against the list, but the documentation
1586 told otherwise. This release fixes the code, so it complies with the
1588 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1589 configuration messages will end up in the logging facility.
1590 * conrtib/fedora: The contributed specfile for Fedora has been
1593 2007-07-05, Version 4.0.5
1594 * Portability: More fixes for OpenBSD have been included.

1616 * iptables plugin: A bug in the configuration routine has been fixed.
1617 Setting a comment in the configfile will no longer cause a
1620 2007-06-03, Version 4.0.0
1621 * collectd: The plugin-infrastructure has been changed to allow for
1622 more types of plugins, namely `write' and `log' plugins.
1623 * collectd: The read-function has been changed to read many plugins in
1624 parallel, using threads. Thus, plugins generally need to use
1625 thread-safe functions from now on.
1626 * collectd: The '-t' command line options allows to perform syntax tests
1627 of the configuration file and exit immediately.
1628 * csv plugin: The new `csv' plugin handles output to `comma separated
1630 * rrdtool plugin: The new `rrdtool' plugin handles output to
1631 RRD-files. Data can be cached to combine multiple updates into one
1632 write to increase IO-performance.
1633 * network plugin: The new `network' plugin handles IO via the network.
1634 It implements a different, much more extensible protocol which can
1635 combine many values in one packet, decreasing the number of UDP-
1636 packets being sent. It can read from and send to the network and
1637 with the appropriate configuration even forward packets to other
1639 * unixsock plugin: The new `unixsock' plugin provides an interface to
1640 communicate with the daemon while it is running. Right now the
1641 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1643 * perl plugin: The new `perl' plugin allows you to write extensions
1644 for collectd in the scripting-language Perl.
1645 * logfile plugin: The new `logfile' plugin writes logmessages to files
1646 or STDOUT or STDERR.
1647 * syslog plugin: The new `syslog' plugin sends logmessages to the
1648 system's syslog daemon.
1649 * entropy plugin: The new `entropy' plugin collects the amount of
1650 entropy currently being available to the system.
1651 * exec plugin: The new `exec' plugin forks child processes and reads
1652 back values provided by the forked processes.
1653 * iptables plugin: The new `iptables' plugin reads counters from
1654 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1656 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1657 to Peter Holik for contributing this plugin.
1658 * nut plugin: The new `nut' plugin connects the upsd of the `network
1659 ups tools' and reads information about the connected UPS.
1660 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1661 connections) field was added by Florent Monbillard.
1662 * collectd-nagios: The new `collectd-nagios' binary queries values
1663 from collectd, parses them and exits according to Nagios-standards.
1664 * manpages: The manpages have been improved a lot.
1666 2007-09-28, Version 3.11.7
1667 * wireless plugin: Correct the handling of cards returning signal and
1668 noise quality as percentage.
1670 2007-08-31, Version 3.11.6

1673 2007-05-29, Version 3.11.5
1674 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1675 * ntpd plugin: Fix a potential buffer overflow.
1676 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1677 were accounted as `zombies'.
1679 2007-04-10, Version 3.11.4
1680 * dns plugin: Change the order of includes to make the plugin compile
1683 2007-03-30, Version 3.11.3
1684 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1685 of the unused `COLLECT_KSTAT'.
1687 2007-02-11, Version 3.11.2
1688 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1689 NULL-pointer may have been passed to `printf' which causes a
1690 segfault with some libcs.
1692 2007-02-10, Version 3.11.1
1693 * df plugin: Some wrong defines have been fixed so the plugin works
1694 under Solaris again.
1695 * dns plugin: The usage of a struct has been fixed to work with
1697 * processes plugin: Some missing defines have been added so the plugin
1698 compiles cleanly under FreeBSD and presumably other UNIXes.
1700 2006-12-22, Version 3.11.0
1701 * collectd: The new command line option `-P' makes it easier for
1702 distributors to change the location of PID-files.
1703 * collectd: The daemon shuts down faster now which makes it easier to
1704 write init.d-scripts for it.
1705 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1706 caused problems every now and then.
1707 * df plugin: New config options allow to ignore certain mountpoints,
1708 filesystem types or devices.
1709 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1710 and interprets it. It collects traffic as well as qtype, opcode and
1712 * email plugin: Sebastian Harl has contributed this plugin which
1713 counts received mails in categories (e. g. ham, spam, virus), spam
1714 score (as given by SpamAssassin) and check types.
1715 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1716 uses `mbmon' to gather information from sensors on the motherboard.
1717 * processes plugin: Collect detailed statistics for configured
1718 processes, that's process and thread count, CPU usage, resident
1719 segment size and pagefaults.
1720 * multimeter plugin: Peter Holik contributed a new plugin which
1721 queries multimeters.
1722 * sensors plugin: Lubos Stanek has put much effort into improving this
1723 plugin, including `extended naming', collection of voltage values
1724 and the possibility to ignore certain values.
1726 2006-12-21, Version 3.10.4
1727 * Max Kellermann has identified a bug in the server routine: When
1728 opening a socket fails the daemon will (re)try opening the socket in
1729 an endless loop, ultimately leading to a `EMFILE' error.
1731 2006-11-04, Version 3.10.3
1732 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1733 ntpd's reply was sent in more than one packet, the buffer size was
1734 calculated incorrectly, resulting in the reading of uninitialized or
1737 2006-11-01, Version 3.10.2
1738 * The sample config file has been improved.
1739 * Errors in the manpages have been corrected.
1740 * The ping-plugin now adds hosts during initialization, not during
1741 startup. This speeds up startup when no network connectivity is
1742 available. Also, the hosts are being added later when the network is
1744 * Improved BSD-support for the df-plugin.
1745 * Fixed syntax errors in the swap-plugin for Mac OS X.
1746 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1748 * Don't disable the mysql-plugin if connecting to the database fails
1749 during initialization. Instead, try again in increasing intervals.
1751 2006-07-19, Version 3.10.1
1752 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1753 the apcups cannot be reached, unconnected sockets will pile up and
1754 eventually lead to `Too many open files' errors.
1756 2006-07-09, Version 3.10.0
1757 * The `disk' plugin has been ported to Darwin.
1758 * The `battery' plugin should work on many Apple computers now.
1759 * The `traffic' plugin can now ignore certain interfaces. Also,
1760 statistics for sent/received packets and errors have been added.
1761 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1762 to Anthony Gialluca for contributing this plugin and providing me
1763 with a test environment :)
1764 * A plugin for monitoring an NTP instance and the local clock drift
1767 2006-06-25, Version 3.9.4
1768 * The Solaris code in the `swap' plugin has been changed to reflect
1769 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1771 * The debugging system has been fixed to work with the Sun libc.
1772 * When built without librrd the variable `operating_mode' could be
1773 uninitialized. Thanks to David Elliot for reporting the bug.
1775 2006-06-01, Version 3.9.3
1776 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1777 operating systems also profit from the changes, but I wasn't able to
1779 * Changed the build system to find the netinet-includes under FreeBSD
1780 and therefore successfully build the `liboping' library there.
1782 2006-05-09, Version 3.9.2
1783 * Applied a patch to the `liboping' library. Due to a bug in the
1784 sequence checking the `ping' plugin stopped working after
1785 approximately 7.6 days.
1787 2006-05-09, Version 3.8.5
1788 * Applied a patch to the `liboping' library. Due to a bug in the
1789 sequence checking the `ping' plugin stopped working after
1790 approximately 7.6 days.
1792 2006-04-21, Version 3.9.1
1793 * Build issues with Solaris and possible other architectures have been
1795 * Problems when building the `apache'-plugin without `libcurl' have
1797 * A bug in the `ping' plugin has been fixed. Sorry folks.
1799 2006-04-02, Version 3.9.0
1800 * A plugin to monitor the Apache webserver has been added.
1801 <http://httpd.apache.org/>
1802 * A plugin to collect statistics about virtual servers using VServer.
1803 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1805 * A plugin for wireless LAN cards has been added. It monitors signal
1806 strength, link quality and noise ratio..
1807 * A plugin for Apple hardware sensors has been added.
1808 * An option to compile collectd with different `step' and `heartbeat'
1809 settings has been added. The size of RRAs is no longer static but
1810 calculated based on the settings for `step' and `width'.
1811 * The `ping' plugin can now be configured to use a certain TTL.
1812 * A plugin to monitor the hardware sensors of Apple computers has been
1814 * The plugins `cpu', `memory', `processes' and `traffic' have been
1815 ported to Mach/Darwin (Mac OS X).
1816 * The `log mode' has been contributed by Christophe Kalt. It writes
1817 the data into text files rather than RRD files.
1819 2006-04-09, Version 3.8.4
1820 * Applied patch by Vincent Stehlé which improves the disk-name
1821 resolution in the `hddtemp' plugin for Linux systems.
1823 2006-04-02, Version 3.8.3
1824 * Applied a patch by James Byers: The MySQL plugin was not working
1825 with MySQL 5.0.2 or later.
1827 2006-03-14, Version 3.8.2
1828 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1829 the GNU libc, because it points to `/etc/fstab' rather than
1832 2006-03-13, Version 3.8.1
1833 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1834 * Fixes in the debian `postinst' and `init.d' scripts.
1836 2006-03-09, Version 3.8.0
1837 * The `ping' plugin no longer uses `libping' but a self written
1838 library named `liboping'. With this library it's possible to ping
1839 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1841 2006-02-18, Version 3.7.2
1842 * A simple bug in the `battery' plugin has been fixed. It should now
1843 work with ACPI based batteries as well. Thanks to Sebastian for
1845 * Fixing a bug that prevented collectd to be built without librrd.
1846 Thanks to Werner Heuser for reporting it.
1848 2006-02-04, Version 3.7.1
1849 * The new network code has been improved to build with older versions
1851 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1852 to Tommie Gannert for this patch.
1854 2006-01-30, Version 3.7.0
1855 * The `battery' plugin has been added. It collects information about
1857 * The MySQL plugin has been improved: It now writes two more RRD
1858 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1859 * The `cpufreq' plugin now reads another file since the file it did
1860 read so far causes much overhead in the kernel. Also, you need root
1861 to read the old file, but not to read the new one.
1862 * The `hddtemp' plugin can now be configured to connect to another
1863 address and/or port than localhost.
1864 * The `df' plugin now prefers `statvfs' over `statfs'.
1865 * The network code has been rewritten. collectd now supports unicast
1866 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1867 be set in the configfile.
1869 2006-01-24, Version 3.6.2
1870 * Due to a bug in the configfile handling collectd wouldn't start in
1871 client mode. This released fixes this.
1873 2006-01-20, Version 3.6.1
1874 * Due to a bug in `configure.in' all modules and the binary were
1875 linked against `libmysqlclient'. This issue is solved by this
1878 2006-01-17, Version 3.6.0
1879 * A config file has been added. This allows for loading only specific
1881 * A `df' plugin has been added.
1882 * A `mysql' plugin has been added.
1883 * The `ping' plugin doesn't entirely give up hope when a socket error
1884 occurred, but will back of and increase the intervals between tries.
1886 2006-01-21, Version 3.5.2
1887 * Fixed yet another bug in the signal handling.. Stupid typo..
1888 * Improved the ping plugin to not give up on socket errors (backport
1891 2005-12-18, Version 3.5.1
1892 * The PID-file is now deleted correctly when shutting down the daemon.
1893 * SIGINT and SIGTERM are now handled correctly.
1895 2005-12-16, Version 3.5.0 (Revision 326)
1896 * A bug in the `load' module under Solaris has been fixed.
1897 * The `users' module has been contributed by Sebastian Harl. It counts
1898 currently logged in users.
1899 * The CPU module now works under FreeBSD without the use of
1900 `libstatgrab', however SMP support is missing.
1901 * The default directories for the RRD files and the PID file now
1902 depend on the compile time setting of `localstatedir'.
1904 2005-11-15, Version 3.4.0 (Revision 236)
1905 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1906 from gentoo's bugzilla for writing the patch.
1907 * The build dependency for librrd has been removed. Binaries built
1908 without librrd are client-only and will multicast their value as
1909 with the `-c' argument.
1910 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1911 * The newly introduced `-f' switch prevents daemon initialization
1912 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1913 Barcellos for this patch.
1915 2005-11-04, Version 3.3.0 (Revision 216)
1916 * New modules have been added:
1917 - `serial', for monitoring traffic on the serial interfaces
1918 - `nfs', for graphing NFS procedure calls
1919 - `tape', traffic from/to tape devices
1920 * The memory.rrd now accepts more than 4Gig of memory.
1922 2005-10-26, Version 3.2.0 (Revision 200)
1923 * Support for graphing the processes has been added (thanks to Lyonel
1925 * If reading from hddtemp fails collectd will increase the time
1926 between polls up to one day.
1927 * The init.d files have been improved.
1928 * Problems with the spec file have been fixed.
1930 2005-10-16, Version 3.1.0 (Revision 194)
1931 * Added the `setsid' syscall to the startup code.
1932 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1934 2005-09-30, Version 3.0.0 (Revision 184)
1935 * The ability to send/receive data to/from the network (think
1936 multicast) has been added.
1937 * Modules have been split up into shared libraries can be loaded at
1938 runtime. The biggest advantage is that the core program doesn't need
1939 to be linked against an external library.
1940 * A patch by George Kargiotakis has been applied: It fixes the sensors
1941 behaviour then more than one sensor is being queried.
1943 2005-09-16, Version 2.1.0 (Revision 172)
1944 * A module for swap statistics has been added.
1946 2005-09-09, Version 2.0.0 (Revision 135)
1947 * Filenames can no longer be configured at program startup. The only
1948 options as of this version are the directory and ping hosts.
1949 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1950 Soft-IRQ statistics are added to `System'.
1951 * Diskstats now collect read and write bytes, not sectors.
1952 * Ping statistics can now be collected for more than one host. There
1953 is no default any more: If no host is given no host will be pinged.
1954 * A self-written patch for libping has been applied so it builds
1957 2005-09-01, Version 1.8.1 (Revision 123)
1958 * Much improved configure-script: libraries and features may now be
1960 * More detailed warnings/error messages when RRD update fails.
1962 2005-08-29, Version 1.8.0:
1963 * Support for collecting disk statistics under Solaris.
1965 2005-08-25, Version 1.7.0:
1966 * Support for libstatgrab[1] for load, memory usage and network
1967 traffic. CPU- and disk-usage are not (yet) supported, since
1968 libstatgrab returns insufficient information. I will contact the
1970 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1971 aren't necessarily counted linear which is now handled correctly.

1974 2005-08-21, Version 1.6.0:
1975 * Basic support for Solaris: System load and cpu-usage can be
1976 collected under Solaris, too. Other stats will follow later.
1977 * Many fixes in the autoconf-script
1978 * Collection/Museum scripts have been added under contrib/museum
1979 * collectd may now be started in unprivileged mode, though ping
1980 statistics will not work.
1982 2005-07-17, Version 1.5.1:
1983 * Diskstats-RRDs now use major/minor for naming. Some systems have
1984 weird strings as disk-names..
1986 2005-07-17, Version 1.5:
1987 * A new module, diskstats, has been added. It collects information
1988 about the disks and partitions.
1990 2005-07-11, Version 1.4.2:
1991 * The meminfo module has been changed to work with more platforms
1992 and/or kernel versions.
1994 2005-07-10, Version 1.4.1: Correct traffic stats
1995 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1996 forgot to correct when I changed that module.
1998 2005-07-09, Version 1.4: More traffic stats
1999 * Traffic is now collected for all interfaces that can be found
2000 * Temperature-statistics are read from lm-sensors if available
2002 2005-07-08, Version 1.3: CPU stats
2003 * Collecting CPU statistics now
2005 2005-07-12, Version 1.2: Using syslog
2006 * collectd is now using the syslog facility to report errors, warnings
2008 * The default directory is now /var/db/collectd
2010 2005-07-10, Version 1.1: Minor changes
2011 * Nothing really useful to say ;)
2013 2005-07-09, Version 1.0: Initial Version
2014 * The following modules are provided:
