987 * perl plugin: Added support for `notification meta data'.
988 * perl plugin: Added support for the `filter chain' infrastructure by
989 allowing plugins to register `matches' and `targets'.
990 * postgresql plugin: The preferred configuration syntax has been
991 updated to be in line with the syntax used by the new dbi and oracle
992 plugins. The compatibility code for the old syntax is present.
993 Support for the new `Result' blocks and the interval parameter has
995 * processes plugin: Stacksize and virtual memory usage statistics have
996 been added. Portability fixes.
997 * rrdcached plugin: This new plugin uses the (still in development)
998 RRD accelerator daemon, rrdcached. This daemon works very similar to
999 the original rrdtool plugin of collectd, but adds some more nice
1001 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1004 2009-05-09, Version 4.5.4
1005 * Build system, various plugins: Many build fixes for FreeBSD,
1006 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1007 for many fixes and providing a build system for many platforms,
1008 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1009 providing an OpenBSD system.
1010 * collectd: Fix a potential race condition when creating directories.
1011 * battery plugin: Don't complain about a missing directory every
1013 * dns plugin: Slight portability fixes.
1014 * exec plugin: Allow executed programs to close STDERR. Thanks to
1015 Thorsten von Eicken for reporting this problem.
1016 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1017 Tomasz Pala for the patch.
1018 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1020 * rrdtool plugin: Fix a possible race condition: If the network plugin
1021 is initialized and dispatches a value before the rrdtool plugin is
1022 initialized, the daemon may crash.
1023 * memory plugin: Fix a potential problem under Solaris.
1025 2009-02-22, Version 4.5.3
1026 * build system: The check for libupsclient even when `pkg-config' is
1028 * collectd: Fix error handling in the global cache.
1029 * Collectd::Unixsock: Error handling has been improved.
1030 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1032 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1033 faults. Thanks to Peter Holik for his patch.
1034 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1035 code. Thanks to "thated" for reporting this.
1037 2009-01-02, Version 4.5.2
1038 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1039 file may be in both locations, especially when the database was
1040 installed in a non-standard path. Thanks to Dusty Doris for
1042 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1043 Solaris, in the configure script automatically.
1044 * build system, tcpconns plugin: Check for `kvm_nlist' and
1045 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1046 library with similar functions to the BSD variant, but doesn't
1047 provide these necessary functions.
1048 * collectd.conf(5): Various fixes and clarifications.
1049 * collectd: Remove a GNUism (unnamed unions), thus improving
1051 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1052 This solves portability problems, especially for Solaris.
1053 * dns plugin: Fix a portability problem with NetBSD.
1054 * filecount plugin: Fix an off-by-one error. This error may cause a
1056 * network plugin: Fix the handling of `type' in the network protocol.
1057 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1058 much larger buffer. This caused the `type' to be transferred much
1059 more often than necessary. In some cases, e. g. the `cpu' and
1060 `cpufreq' plugins being used at the same time, data may be corrupted
1061 in those files. Thanks to Bruno Prémont for debugging and reporting
1063 * processes plugin: Fix a possible segmentation fault when specifying
1064 invalid configuration options.
1065 * unixsock plugin: Make sure the initialization function is run only
1066 once. This resolves a file descriptor leak under systems which run
1067 the initialization more than once, such as Solaris.
1069 2008-10-16, Version 4.5.1
1070 * build system: Change `--enable-<plugin>' to abort with an error if
1071 dependencies are not met. Thanks to Bruno Prémont for the patch.
1072 Also, the poisoning of various string functions has been restricted
1074 * collectd: Fix a memory leak in the global value cache. With every
1075 *missing* value a couple of bytes would be leaked. Another memory
1076 leak in the configuration handling code has been fixed. Thanks to
1077 Niraj Tolia for reporting these issues.
1078 * collectd: Fix an off-by-one error in the ignorelist functionality.
1079 When using regular expressions, the last character would be missing,
1080 possibly matching differently from what one would expect.
1081 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1083 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1084 Linzberger for reporting the bug.
1085 * iptables plugin: Fix an off-by-one error. If a string was just one
1086 character too long, it was truncated instead of reporting an error.
1087 * network plugin: Fix a memory leak in the configuration handling
1088 code. Thanks to Niraj Tolia for reporting this issue.
1089 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1090 * postgresql plugin: Don't reopen connection during reinitialization.
1091 This fixes a bug under Solaris and potentially other platforms.
1092 Missing calls to `PQclear' have been added, too. This fixes memory
1093 leaks. Thanks to ``Admin'' for reporting these bugs.
1094 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1096 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1097 problems with some `libc's. Thanks to Matthias Lay for reporting the
1100 2008-09-04, Version 4.5.0
1101 * collectd: Added the ability to flush certain identifiers.
1102 * collectd: The concept of `notification meta data' has been
1104 * filecount plugin: The new filecount plugin counts the number of
1105 files in a directory and its subdirectories.
1106 * ipmi plugin: Sensor names have been changed to ensure unique names.
1107 Notifications upon added and removed sensors can now be generated.
1108 * notify_desktop plugin: This new plugin sends notifications to the
1109 X desktop using the structure defined in the `Desktop Notification
1111 * notify_email plugin: This new plugin sends out notifications via
1112 email, using the `esmtp' library.
1113 * onewire plugin: The new experimental(!) onewire plugin reads values,
1114 such as temperatures, from sensors connected to the computer via the
1116 * perl plugin: Improved synchronized access to internal data structures
1117 and fixed a possible dead-lock.
1118 * perl plugin: Added the ability to flush certain identifiers and marked
1119 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1121 * perl plugin: Added the ability to configure Perl plugins.
1122 * postgresql plugin: The new postgresql plugin collects statistics
1123 about or from a PostgreSQL database.
1124 * processes plugin: The `ProcessMatch' option has been added.
1125 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1127 * tcpconns plugin: This plugin has been ported to OpenBSD.
1128 * thermal plugin: The new thermal plugin collects system temperatures
1129 using Linux ACPI thermal zone data.
1131 2009-01-02, Version 4.4.5
1132 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1133 file may be in both locations, especially when the database was
1134 installed in a non-standard path. Thanks to Dusty Doris for
1136 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1137 Solaris, in the configure script automatically.
1138 * collectd.conf(5): Various fixes and clarifications.
1139 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1140 portability problems, especially for Solaris.
1141 * dns plugin: Fix a portability problem with NetBSD.
1142 * network plugin: Fix the handling of `type' in the network protocol.
1143 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1144 much larger buffer. This caused the `type' to be transferred much
1145 more often than necessary. In some cases, e. g. the `cpu' and
1146 `cpufreq' plugins being used at the same time, data may be corrupted
1147 in those files. Thanks to Bruno Prémont for debugging and reporting
1149 * unixsock plugin: Make sure the initialization function is run only
1150 once. This resolves a file descriptor leak under systems which run
1151 the initialization more than once, such as Solaris.
1153 2008-10-16, Version 4.4.4
1154 * build system: Change `--enable-<plugin>' to abort with an error if
1155 dependencies are not met. Thanks to Bruno Prémont for the patch.
1156 Also, the poisoning of various string functions has been restricted
1158 * collectd: Fix a memory leak in the global value cache. With every
1159 *missing* value a couple of bytes would be leaked. Another memory
1160 leak in the configuration handling code has been fixed. Thanks to
1161 Niraj Tolia for reporting these issues.
1162 * collectd: Fix an off-by-one error in the ignorelist functionality.
1163 When using regular expressions, the last character would be missing,
1164 possibly matching differently from what one would expect.
1165 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1167 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1168 Linzberger for reporting the bug.
1169 * network plugin: Fix a memory leak in the configuration handling
1170 code. Thanks to Niraj Tolia for reporting this issue.
1171 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1172 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1173 problems with some `libc's. Thanks to Matthias Lay for reporting the
1176 2008-09-01, Version 4.4.3
1177 * collectd: Fix a memory leak in the threshold checking code.
1178 * memcached plugin: Fix a too short timeout and a related file
1180 * memory plugin: A typo in the libstatgrab code has been fixed.
1181 * snmp plugin: Fix a possible memory leak.
1183 2008-07-15, Version 4.4.2
1184 * build system: Use pkg-config to detect the upsclient library.
1185 * collectd: Try even harder to determine the endianess of the
1186 architecture collectd is being built on.
1187 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1189 * dns plugin: Fix compilation errors with BIND versions 19991001
1191 * network plugin: Bugfix in the init routine: The init function
1192 cleared a buffer regardless of its contents. This could lead to lost
1193 values under Solaris.
1194 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1195 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1197 * wireless plugin: Work around incorrect noise and power values
1198 returned by some broken drivers.
1200 2008-06-03, Version 4.4.1
1201 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1202 to kyrone for reporting this.
1203 * collectd: Fixed min/max output in notifications generated by
1205 * collectd-nagios: Fix the protocol used to communicate with the
1207 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1208 initialization has errors. An issue with Perl 5.10 has been fixed.
1209 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1210 René Rebe and Siegmund Gorr for reporting this.
1212 2008-05-06, Version 4.4.0
1213 * collectd: Internal code cleanups.
1214 * collectd: Added support for a `Flush' command in the unixsock and
1215 exec plugins. This command can be used to force a plugin (or all) to
1216 flush its values to disk.
1217 * collectd: Thresholds can now be configured to apply to one data
1218 source only, making it possible to configure different thresholds
1219 for each data source.
1220 * apache, nginx plugins: Added the possibility to disable host and/or
1222 * ascent plugin: The new ascent plugin reads and parses the statistics
1223 page of an Ascent server.
1224 * cpu plugin: Support for the statgrab library has been added.
1225 * disk plugin: The possibility to ignore certain disks or collect only
1226 specific disks has been added.

1228 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1229 sensor values via IPMI, the intelligent platform management
1231 * iptables plugin: The iptc library that is used by the iptables
1232 plugin has been added to the distribution, because it is not
1233 provided by all distributions and removed from at least one.
1234 * powerdns plugin: The new powerdns plugin reads statistics from an
1235 authoritative or a recursing PowerDNS name server.
1236 * rrdtool plugin: The size of the files generated with the default
1237 configuration has been decreased.
1238 * tail plugin: The new tail plugin can be used to gather statistics by
1239 continuously reading from log files.
1240 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1241 TeamSpeak2 server and collects statistics about the number of users
1242 and number of channels.
1243 * users plugin: Support for the statgrab library has been added.
1244 * vmem plugin: The new vmem plugin collects very detailed statistics
1245 about the virtual memory subsystem of Linux.
1247 2008-08-30, Version 4.3.4
1248 * Build system: Improved detection of and linking with the statgrab
1250 * collectd: Portability fixes, especially to determine endianess more
1252 * Various plugins: Fix format strings.
1253 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1254 again has been applied.
1255 * memcached plugin: Fix a too short timeout and a related file
1257 * memory plugin: A typo in the libstatgrab code has been fixed.
1258 * network plugin: A fix in the initialization function solves problems
1260 * nginx plugin: A thread-unsafe function has been replaced.
1261 * vserver plugin: A thread-unsafe function has been replaced.
1262 * wireless plugin: A work-around for broken wireless drivers has been

1266 * build system: Improved detection of several libraries, especially if
1267 they are in non-standard paths.
1268 * build system: Portability fixes: Automatically define "_REENTRANT"
1269 if the libc expects it.
1270 * collectd: Error and warning messages have been improved.
1271 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1273 * apache plugin: Allocate new memory when reading a webpage instead of
1274 using a buffer of static size.
1275 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1277 * hddtemp plugin: Error and warning messages have been improved.
1278 * sensors plugin: Fix sensor collection for some chip types.
1280 2008-03-29, Version 4.3.2
1281 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1282 `Persist' threshold options.
1283 * collectd: Fix handling of missing values in the global value cache.
1284 * collectd: Improved error messages when parsing the configuration.
1285 * sensors plugin: Fix temperature collection with libsensors4.
1286 * unixsock plugin: Fix mixed input and output operation on streams.
1287 * wireless plugin: Fix reading noise value.
1289 2008-03-05, Version 4.3.1
1290 * exec plugin: Set supplementary group IDs.
1292 + Use `memcpy' when constructing/parsing a package to avoid
1293 alignment problems on weird architectures, such as Sparc.
1294 + Translate doubles to/from the x86 byte representation to ensure
1295 cross-platform compatibility.
1296 * ping plugin: Correct the handling of the `TTL' setting.
1297 * swap plugin: Reapply a patch for Solaris.
1298 * tcpconns plugin: Portability improvements.
1300 2008-02-18, Version 4.3.0
1301 * collectd: Notifications have been added to the daemon. Notifications
1302 are status messages that may be associated with a data instance.
1303 * collectd: Threshold checking has been added to the daemon. This
1304 means that you can configure threshold values for each data
1305 instance. If this threshold is exceeded a notification will be
1307 * collectd: The new `FQDNLookup' option tells the daemon to use the
1308 full qualified domain name as the hostname, not just the host part
1309 es returned by `gethostname(2)'.
1310 * collectd: Support for more than one `TypesDB' file has been added.
1311 This is useful when one such file is included in a package but one
1312 wants to add custom type definitions.
1313 * collectd: The `Include' config option has been expanded to handle
1314 entire directories and shell wildcards.
1315 * collectdmon: The new `collectdmon' binary detects when collectd
1316 terminates and automatically restarts it again.
1317 * csv plugin: The CSV plugin is now able to store counter values as a
1318 rate, using the `StoreRates' configuration option.
1319 * exec plugin: Handling of notifications has been added and the
1320 ability to pass arguments to the executed programs has been added.
1321 * hddtemp plugin: The new `TranslateDevicename' option lets you
1322 disable the translation from device names to major-minor-numbers.
1323 * logfile plugin: Handling of notifications has been added.
1324 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1325 domain name lookups in this plugin.
1326 * perl plugin: Many internal changes added support for handling multiple
1327 threads making the plugin reasonably usable inside collectd. The API has
1328 been extended to support notifications and export global variables to
1329 Perl plugins; callbacks now have to be identified by name rather than a
1330 pointer to a subroutine. The plugin is no longer experimental.
1331 * uuid plugin: The new UUID plugin sets the hostname to an unique
1332 identifier for this host. This is meant for setups where each client
1333 may migrate to another physical host, possibly going through one or
1334 more name changes in the process. Thanks to Richard Jones from
1335 Red Hat's Emerging Technology group for this plugin.
1336 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1337 CPU, disk and network statistics about guest systems on the same
1338 physical server. Thanks to Richard Jones from Red Hat's Emerging
1339 Technology group for this plugin.
1341 2008-04-22, Version 4.2.7
1342 * build system: Improved detection of several libraries, especially if
1343 they are in non-standard paths.
1344 * build system: Portability fixes: Automatically define "_REENTRANT"
1345 if the libc expects it.
1346 * collectd: Error and warning messages have been improved.
1347 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1349 * apache plugin: Allocate new memory when reading a webpage instead of
1350 using a buffer of static size.
1351 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1353 * hddtemp plugin: Error and warning messages have been improved.
1354 * sensors plugin: Fix sensor collection for some chip types.
1356 2008-03-29, Version 4.2.6
1357 * collectd: Improved error messages when parsing the configuration.
1358 * sensors plugin: Fix temperature collection with libsensors4.
1359 * unixsock plugin: Fix mixed input and output operation on streams.
1360 * wireless plugin: Fix reading noise value.
1362 2008-03-04, Version 4.2.5
1363 * apache plugin: Improved initialization and error messages.
1364 * exec plugin: Set supplementary group IDs.
1366 + Create separate threads for reading from the socket and parsing
1367 and dispatching incoming packets. Versions prior to this may have
1368 problems in high-load situations, where the socket receive buffers
1369 overflows, resulting in gaps in the data.
1370 + Use `memcpy' when constructing/parsing a package to avoid
1371 alignment problems on weird architectures, such as Sparc.
1372 + Translate doubles to/from the x86 byte representation to ensure
1373 cross-platform compatibility.
1374 * ping plugin: Correct the handling of the `TTL' setting.
1375 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1376 * swap plugin: Reapply a patch for Solaris.
1377 * tcpconns plugin: Portability improvements.
1379 2008-01-21, Version 4.2.4
1380 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1381 the permission on the socket as documented in the manpage. Thanks to
1382 Evgeny Chukreev for fixing this issue.
1383 * collectd: The documentation has been improved.
1385 2007-12-28, Version 4.2.3
1386 * sensors plugin: Updated the plugin to build and work with version 3
1387 of the libsensors library.
1389 2007-12-15, Version 4.2.2
1390 * nginx plugin: Incorrect comparison of strings lead to a segfault
1391 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1393 * logfile plugin: The config option `Timestamp' was handled
1394 incorrectly and basically always active. Thanks to Luke Heberling
1397 2007-11-08, Version 4.2.1
1398 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1399 enabled on the host.
1400 * snmp plugin: Fix a memory leak.
1402 2007-10-27, Version 4.2.0
1403 * collectd: The new config option `Include' lets you include other
1404 configfiles and thus split up your config into smaller parts. This
1405 may be especially interesting for the snmp plugin to keep the data
1406 definitions separate from the host definitions.
1407 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1408 (number of connections, octets and packets for each service and
1409 destination). Thanks to Sebastian Harl for this plugin.
1410 * memcached plugin: The new `memcached' plugin connects to a memcached
1411 daemon process and collects statistics of this distributed caching
1412 system. Thanks to Antony Dovgal for contributing this plugin.
1413 * nginx plugin: The new `nginx' plugin reads the status page of an
1414 nginx daemon and saves the handled connections and requests.
1415 * perl plugin: Many changes, including the added `EnableDebugger'
1416 config option which lets you debug your Perl plugins more easily.
1417 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1418 be more thread-safe otherwise by locking calls to the library.
1419 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1420 correct the values returned by SNMP-agents. If a <data> block is
1421 defined as `table' the instance is now optional. The sequence number
1422 is used as the type-instance in this case. The new `InstancePrefix'
1423 option allows to add arbitrary prefixes to the type-instance.
1424 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1425 certain TCP connections and what state they're in. This can be used
1426 to see how many connections your FTP server has to handle or how
1427 many outgoing connections your mailserver has open.
1429 2008-01-11, Version 4.1.6
1430 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1431 the permission on the socket as documented in the manpage. Thanks to
1432 Evgeny Chukreev for fixing this issue.
1433 * collectd: The documentation has been improved.
1435 2007-12-27, Version 4.1.5
1436 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1438 * sensors plugin: Updated the plugin to build and work with version 3
1439 of the libsensors library.
1441 2007-11-08, Version 4.1.4
1442 * Build system: Improve detection of the rrd library, especially if
1443 it's in a non-standard location.
1444 * Build system: A bug when parsing the argument for
1445 `--with-libnetsnmp' has been fixed.
1446 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1447 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1448 a deadlock or delay when shutting down the daemon.
1449 * snmp plugin: Fix a memory leak.
1451 2007-10-24, Version 4.1.3
1452 * collectd: A build issue under Solaris has been resolved by renaming
1454 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1455 be more thread-safe otherwise by locking calls to the library.
1457 2007-09-28, Version 4.1.2
1458 * apcups plugin: Fix reporting of the `load percent' data.
1459 * wireless plugin: Correct the handling of cards returning signal and
1460 noise quality as percentage.
1461 * perl plugin: Fix a possible buffer overflow in get_module_name().
1462 * build system: Further improve the detection of libraries.
1463 * netlink plugin: Build issues under some older versions of the Linux
1464 includes (i. e. Debian Sarge) have been fixed.

1480 whatever the client thinks is `now'..
1482 2007-09-01, Version 4.1.0
1483 * Build system: The build system has been changed to automatically
1484 disable all plugins, which are missing dependencies. The dependency
1485 checking has been removed from the plugins themselves to remove
1487 * Flexible interval: The interval of collected data is now sent along
1488 with the data itself over the network, so that the interval-settings
1489 of server and clients no longer needs to match.
1490 * netlink plugin: The new `netlink' plugin connects to the Linux
1491 kernel using a netlink socket and uses it to query information about
1492 interfaces, qdiscs and classes.
1493 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1494 to not block data collection.
1495 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1496 network devices, such as switches, routers, thermometers, rack
1497 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1499 * unixsock plugin: Added the `LISTVAL' command.
1500 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1501 of music played with xmms.

1507 * perl plugin: Fix a possible buffer overflow in get_module_name().
1509 2007-09-12, Version 4.0.8
1510 * collectd: The `sstrerror' function was improved to work correctly
1511 with the broken GNU version of `strerror_r'.
1512 * collectd: Write an error message to STDERR when loading of a plugin
1514 * apcups plugin: Fix the `types' used to submit the values: They still
1515 has an `apcups_' prefix which doesn't work anymore.
1516 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1517 whatever the client thinks is `now'..
1519 2007-08-26, Version 4.0.7
1520 * documentation: Some typos have been fixed and some information has
1522 * build system: Many fixes for detecting libraries in unusual places,
1523 such as on RedHat systems. The affected libraries are `libcurl',
1524 `libmysql', and `libupsclient'.
1525 * network plugin: Allow the `Port' option to be specified as a number
1526 (i. e. without quotes).
1527 * nut plugin: A fix allows linking the nut plugin against
1528 libupsclient, version >= 2.2.0.
1529 * processes plugin: Fix a potential segmentation fault.
1531 2007-07-30, Version 4.0.6
1532 * sensors plugin: Fix the ignorelist functionality: Only the `type
1533 instance' was used to match against the list, but the documentation
1534 told otherwise. This release fixes the code, so it complies with the
1536 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1537 configuration messages will end up in the logging facility.
1538 * conrtib/fedora: The contributed specfile for Fedora has been
1541 2007-07-05, Version 4.0.5
1542 * Portability: More fixes for OpenBSD have been included.
1544 2007-06-24, Version 4.0.4

1561 they're given in numerically form.
1563 2007-06-07, Version 4.0.1
1564 * iptables plugin: A bug in the configuration routine has been fixed.
1565 Setting a comment in the configfile will no longer cause a
1568 2007-06-03, Version 4.0.0
1569 * collectd: The plugin-infrastructure has been changed to allow for
1570 more types of plugins, namely `write' and `log' plugins.
1571 * collectd: The read-function has been changed to read many plugins in
1572 parallel, using threads. Thus, plugins generally need to use
1573 thread-safe functions from now on.
1574 * collectd: The '-t' command line options allows to perform syntax tests
1575 of the configuration file and exit immediately.
1576 * csv plugin: The new `csv' plugin handles output to `comma separated
1578 * rrdtool plugin: The new `rrdtool' plugin handles output to
1579 RRD-files. Data can be cached to combine multiple updates into one
1580 write to increase IO-performance.
1581 * network plugin: The new `network' plugin handles IO via the network.
1582 It implements a different, much more extensible protocol which can
1583 combine many values in one packet, decreasing the number of UDP-
1584 packets being sent. It can read from and send to the network and
1585 with the appropriate configuration even forward packets to other
1587 * unixsock plugin: The new `unixsock' plugin provides an interface to
1588 communicate with the daemon while it is running. Right now the
1589 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1591 * perl plugin: The new `perl' plugin allows you to write extensions
1592 for collectd in the scripting-language Perl.
1593 * logfile plugin: The new `logfile' plugin writes logmessages to files
1594 or STDOUT or STDERR.
1595 * syslog plugin: The new `syslog' plugin sends logmessages to the
1596 system's syslog daemon.
1597 * entropy plugin: The new `entropy' plugin collects the amount of
1598 entropy currently being available to the system.
1599 * exec plugin: The new `exec' plugin forks child processes and reads
1600 back values provided by the forked processes.
1601 * iptables plugin: The new `iptables' plugin reads counters from
1602 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1604 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1605 to Peter Holik for contributing this plugin.
1606 * nut plugin: The new `nut' plugin connects the upsd of the `network
1607 ups tools' and reads information about the connected UPS.
1608 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1609 connections) field was added by Florent Monbillard.
1610 * collectd-nagios: The new `collectd-nagios' binary queries values
1611 from collectd, parses them and exits according to Nagios-standards.
1612 * manpages: The manpages have been improved a lot.
1614 2007-09-28, Version 3.11.7
1615 * wireless plugin: Correct the handling of cards returning signal and
1616 noise quality as percentage.
1618 2007-08-31, Version 3.11.6
1619 * processes plugin: Fix a potential segmentation fault.
1621 2007-05-29, Version 3.11.5
1622 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1623 * ntpd plugin: Fix a potential buffer overflow.
1624 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1625 were accounted as `zombies'.
1627 2007-04-10, Version 3.11.4
1628 * dns plugin: Change the order of includes to make the plugin compile
1631 2007-03-30, Version 3.11.3
1632 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1633 of the unused `COLLECT_KSTAT'.
1635 2007-02-11, Version 3.11.2
1636 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1637 NULL-pointer may have been passed to `printf' which causes a
1638 segfault with some libcs.
1640 2007-02-10, Version 3.11.1
1641 * df plugin: Some wrong defines have been fixed so the plugin works
1642 under Solaris again.
1643 * dns plugin: The usage of a struct has been fixed to work with
1645 * processes plugin: Some missing defines have been added so the plugin
1646 compiles cleanly under FreeBSD and presumably other UNIXes.
1648 2006-12-22, Version 3.11.0
1649 * collectd: The new command line option `-P' makes it easier for
1650 distributors to change the location of PID-files.
1651 * collectd: The daemon shuts down faster now which makes it easier to
1652 write init.d-scripts for it.
1653 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1654 caused problems every now and then.
1655 * df plugin: New config options allow to ignore certain mountpoints,
1656 filesystem types or devices.
1657 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1658 and interprets it. It collects traffic as well as qtype, opcode and
1660 * email plugin: Sebastian Harl has contributed this plugin which
1661 counts received mails in categories (e. g. ham, spam, virus), spam
1662 score (as given by SpamAssassin) and check types.
1663 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1664 uses `mbmon' to gather information from sensors on the motherboard.
1665 * processes plugin: Collect detailed statistics for configured
1666 processes, that's process and thread count, CPU usage, resident
1667 segment size and pagefaults.
1668 * multimeter plugin: Peter Holik contributed a new plugin which
1669 queries multimeters.
1670 * sensors plugin: Lubos Stanek has put much effort into improving this
1671 plugin, including `extended naming', collection of voltage values
1672 and the possibility to ignore certain values.
1674 2006-12-21, Version 3.10.4
1675 * Max Kellermann has identified a bug in the server routine: When
1676 opening a socket fails the daemon will (re)try opening the socket in
1677 an endless loop, ultimately leading to a `EMFILE' error.
1679 2006-11-04, Version 3.10.3
1680 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1681 ntpd's reply was sent in more than one packet, the buffer size was
1682 calculated incorrectly, resulting in the reading of uninitialized or
1685 2006-11-01, Version 3.10.2
1686 * The sample config file has been improved.
1687 * Errors in the manpages have been corrected.
1688 * The ping-plugin now adds hosts during initialization, not during
1689 startup. This speeds up startup when no network connectivity is
1690 available. Also, the hosts are being added later when the network is
1692 * Improved BSD-support for the df-plugin.
1693 * Fixed syntax errors in the swap-plugin for Mac OS X.
1694 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1696 * Don't disable the mysql-plugin if connecting to the database fails
1697 during initialization. Instead, try again in increasing intervals.
1699 2006-07-19, Version 3.10.1
1700 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1701 the apcups cannot be reached, unconnected sockets will pile up and
1702 eventually lead to `Too many open files' errors.
1704 2006-07-09, Version 3.10.0
1705 * The `disk' plugin has been ported to Darwin.
1706 * The `battery' plugin should work on many Apple computers now.
1707 * The `traffic' plugin can now ignore certain interfaces. Also,
1708 statistics for sent/received packets and errors have been added.
1709 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1710 to Anthony Gialluca for contributing this plugin and providing me
1711 with a test environment :)
1712 * A plugin for monitoring an NTP instance and the local clock drift
1715 2006-06-25, Version 3.9.4
1716 * The Solaris code in the `swap' plugin has been changed to reflect
1717 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1719 * The debugging system has been fixed to work with the Sun libc.
1720 * When built without librrd the variable `operating_mode' could be
1721 uninitialized. Thanks to David Elliot for reporting the bug.
1723 2006-06-01, Version 3.9.3
1724 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1725 operating systems also profit from the changes, but I wasn't able to
1727 * Changed the build system to find the netinet-includes under FreeBSD
1728 and therefore successfully build the `liboping' library there.
1730 2006-05-09, Version 3.9.2
1731 * Applied a patch to the `liboping' library. Due to a bug in the
1732 sequence checking the `ping' plugin stopped working after
1733 approximately 7.6 days.
1735 2006-05-09, Version 3.8.5
1736 * Applied a patch to the `liboping' library. Due to a bug in the
1737 sequence checking the `ping' plugin stopped working after
1738 approximately 7.6 days.
1740 2006-04-21, Version 3.9.1
1741 * Build issues with Solaris and possible other architectures have been
1743 * Problems when building the `apache'-plugin without `libcurl' have
1745 * A bug in the `ping' plugin has been fixed. Sorry folks.
1747 2006-04-02, Version 3.9.0
1748 * A plugin to monitor the Apache webserver has been added.
1749 <http://httpd.apache.org/>
1750 * A plugin to collect statistics about virtual servers using VServer.
1751 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1753 * A plugin for wireless LAN cards has been added. It monitors signal
1754 strength, link quality and noise ratio..
1755 * A plugin for Apple hardware sensors has been added.
1756 * An option to compile collectd with different `step' and `heartbeat'
1757 settings has been added. The size of RRAs is no longer static but
1758 calculated based on the settings for `step' and `width'.
1759 * The `ping' plugin can now be configured to use a certain TTL.
1760 * A plugin to monitor the hardware sensors of Apple computers has been
1762 * The plugins `cpu', `memory', `processes' and `traffic' have been
1763 ported to Mach/Darwin (Mac OS X).
1764 * The `log mode' has been contributed by Christophe Kalt. It writes
1765 the data into text files rather than RRD files.
1767 2006-04-09, Version 3.8.4
1768 * Applied patch by Vincent Stehlé which improves the disk-name
1769 resolution in the `hddtemp' plugin for Linux systems.
1771 2006-04-02, Version 3.8.3
1772 * Applied a patch by James Byers: The MySQL plugin was not working
1773 with MySQL 5.0.2 or later.
1775 2006-03-14, Version 3.8.2
1776 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1777 the GNU libc, because it points to `/etc/fstab' rather than
1780 2006-03-13, Version 3.8.1
1781 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1782 * Fixes in the debian `postinst' and `init.d' scripts.
1784 2006-03-09, Version 3.8.0
1785 * The `ping' plugin no longer uses `libping' but a self written
1786 library named `liboping'. With this library it's possible to ping
1787 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1789 2006-02-18, Version 3.7.2
1790 * A simple bug in the `battery' plugin has been fixed. It should now
1791 work with ACPI based batteries as well. Thanks to Sebastian for
1793 * Fixing a bug that prevented collectd to be built without librrd.
1794 Thanks to Werner Heuser for reporting it.
1796 2006-02-04, Version 3.7.1
1797 * The new network code has been improved to build with older versions
1799 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1800 to Tommie Gannert for this patch.
1802 2006-01-30, Version 3.7.0
1803 * The `battery' plugin has been added. It collects information about
1805 * The MySQL plugin has been improved: It now writes two more RRD
1806 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1807 * The `cpufreq' plugin now reads another file since the file it did
1808 read so far causes much overhead in the kernel. Also, you need root
1809 to read the old file, but not to read the new one.
1810 * The `hddtemp' plugin can now be configured to connect to another
1811 address and/or port than localhost.
1812 * The `df' plugin now prefers `statvfs' over `statfs'.
1813 * The network code has been rewritten. collectd now supports unicast
1814 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1815 be set in the configfile.
1817 2006-01-24, Version 3.6.2
1818 * Due to a bug in the configfile handling collectd wouldn't start in
1819 client mode. This released fixes this.
1821 2006-01-20, Version 3.6.1
1822 * Due to a bug in `configure.in' all modules and the binary were
1823 linked against `libmysqlclient'. This issue is solved by this
1826 2006-01-17, Version 3.6.0
1827 * A config file has been added. This allows for loading only specific
1829 * A `df' plugin has been added.
1830 * A `mysql' plugin has been added.
1831 * The `ping' plugin doesn't entirely give up hope when a socket error
1832 occurred, but will back of and increase the intervals between tries.
1834 2006-01-21, Version 3.5.2
1835 * Fixed yet another bug in the signal handling.. Stupid typo..
1836 * Improved the ping plugin to not give up on socket errors (backport
1839 2005-12-18, Version 3.5.1
1840 * The PID-file is now deleted correctly when shutting down the daemon.
1841 * SIGINT and SIGTERM are now handled correctly.
1843 2005-12-16, Version 3.5.0 (Revision 326)
1844 * A bug in the `load' module under Solaris has been fixed.
1845 * The `users' module has been contributed by Sebastian Harl. It counts
1846 currently logged in users.
1847 * The CPU module now works under FreeBSD without the use of
1848 `libstatgrab', however SMP support is missing.
1849 * The default directories for the RRD files and the PID file now
1850 depend on the compile time setting of `localstatedir'.
1852 2005-11-15, Version 3.4.0 (Revision 236)
1853 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1854 from gentoo's bugzilla for writing the patch.
1855 * The build dependency for librrd has been removed. Binaries built
1856 without librrd are client-only and will multicast their value as
1857 with the `-c' argument.
1858 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1859 * The newly introduced `-f' switch prevents daemon initialization
1860 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1861 Barcellos for this patch.
1863 2005-11-04, Version 3.3.0 (Revision 216)
1864 * New modules have been added:
1865 - `serial', for monitoring traffic on the serial interfaces
1866 - `nfs', for graphing NFS procedure calls
1867 - `tape', traffic from/to tape devices
1868 * The memory.rrd now accepts more than 4Gig of memory.
1870 2005-10-26, Version 3.2.0 (Revision 200)
1871 * Support for graphing the processes has been added (thanks to Lyonel

1874 between polls up to one day.
1875 * The init.d files have been improved.
1876 * Problems with the spec file have been fixed.
1878 2005-10-16, Version 3.1.0 (Revision 194)
1879 * Added the `setsid' syscall to the startup code.
1880 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1882 2005-09-30, Version 3.0.0 (Revision 184)
1883 * The ability to send/receive data to/from the network (think
1884 multicast) has been added.
1885 * Modules have been split up into shared libraries can be loaded at
1886 runtime. The biggest advantage is that the core program doesn't need
1887 to be linked against an external library.
1888 * A patch by George Kargiotakis has been applied: It fixes the sensors
1889 behaviour then more than one sensor is being queried.
1891 2005-09-16, Version 2.1.0 (Revision 172)
1892 * A module for swap statistics has been added.
1894 2005-09-09, Version 2.0.0 (Revision 135)
1895 * Filenames can no longer be configured at program startup. The only
1896 options as of this version are the directory and ping hosts.
1897 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1898 Soft-IRQ statistics are added to `System'.
1899 * Diskstats now collect read and write bytes, not sectors.
1900 * Ping statistics can now be collected for more than one host. There
1901 is no default any more: If no host is given no host will be pinged.
1902 * A self-written patch for libping has been applied so it builds
1905 2005-09-01, Version 1.8.1 (Revision 123)
1906 * Much improved configure-script: libraries and features may now be
1908 * More detailed warnings/error messages when RRD update fails.
1910 2005-08-29, Version 1.8.0:
1911 * Support for collecting disk statistics under Solaris.
1913 2005-08-25, Version 1.7.0:
1914 * Support for libstatgrab[1] for load, memory usage and network
1915 traffic. CPU- and disk-usage are not (yet) supported, since
1916 libstatgrab returns insufficient information. I will contact the
1918 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1919 aren't necessarily counted linear which is now handled correctly.
1920 [1]: http://www.i-scream.org/libstatgrab/
1922 2005-08-21, Version 1.6.0:
1923 * Basic support for Solaris: System load and cpu-usage can be
1924 collected under Solaris, too. Other stats will follow later.
1925 * Many fixes in the autoconf-script
1926 * Collection/Museum scripts have been added under contrib/museum
1927 * collectd may now be started in unprivileged mode, though ping
1928 statistics will not work.
1930 2005-07-17, Version 1.5.1:
1931 * Diskstats-RRDs now use major/minor for naming. Some systems have
1932 weird strings as disk-names..
1934 2005-07-17, Version 1.5:
1935 * A new module, diskstats, has been added. It collects information
1936 about the disks and partitions.
1938 2005-07-11, Version 1.4.2:
1939 * The meminfo module has been changed to work with more platforms
1940 and/or kernel versions.
1942 2005-07-10, Version 1.4.1: Correct traffic stats
1943 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1944 forgot to correct when I changed that module.
