991 faults. Thanks to Peter Holik for his patch.
992 * tcpconns plugin: An endianness problem has been fixed in the *BSD
993 code. Thanks to "thated" for reporting this.
995 2009-01-02, Version 4.5.2
996 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
997 file may be in both locations, especially when the database was
998 installed in a non-standard path. Thanks to Dusty Doris for
1000 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1001 Solaris, in the configure script automatically.
1002 * build system, tcpconns plugin: Check for `kvm_nlist' and
1003 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1004 library with similar functions to the BSD variant, but doesn't
1005 provide these necessary functions.
1006 * collectd.conf(5): Various fixes and clarifications.
1007 * collectd: Remove a GNUism (unnamed unions), thus improving
1009 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1010 This solves portability problems, especially for Solaris.
1011 * dns plugin: Fix a portability problem with NetBSD.
1012 * filecount plugin: Fix an off-by-one error. This error may cause a
1014 * network plugin: Fix the handling of `type' in the network protocol.
1015 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1016 much larger buffer. This caused the `type' to be transferred much
1017 more often than necessary. In some cases, e. g. the `cpu' and
1018 `cpufreq' plugins being used at the same time, data may be corrupted
1019 in those files. Thanks to Bruno Prémont for debugging and reporting
1021 * processes plugin: Fix a possible segmentation fault when specifying
1022 invalid configuration options.
1023 * unixsock plugin: Make sure the initialization function is run only
1024 once. This resolves a file descriptor leak under systems which run
1025 the initialization more than once, such as Solaris.
1027 2008-10-16, Version 4.5.1
1028 * build system: Change `--enable-<plugin>' to abort with an error if
1029 dependencies are not met. Thanks to Bruno Prémont for the patch.
1030 Also, the poisoning of various string functions has been restricted
1032 * collectd: Fix a memory leak in the global value cache. With every
1033 *missing* value a couple of bytes would be leaked. Another memory
1034 leak in the configuration handling code has been fixed. Thanks to
1035 Niraj Tolia for reporting these issues.
1036 * collectd: Fix an off-by-one error in the ignorelist functionality.
1037 When using regular expressions, the last character would be missing,
1038 possibly matching differently from what one would expect.
1039 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1041 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1042 Linzberger for reporting the bug.
1043 * iptables plugin: Fix an off-by-one error. If a string was just one
1044 character too long, it was truncated instead of reporting an error.
1045 * network plugin: Fix a memory leak in the configuration handling
1046 code. Thanks to Niraj Tolia for reporting this issue.
1047 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1048 * postgresql plugin: Don't reopen connection during reinitialization.
1049 This fixes a bug under Solaris and potentially other platforms.
1050 Missing calls to `PQclear' have been added, too. This fixes memory
1051 leaks. Thanks to ``Admin'' for reporting these bugs.
1052 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1054 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1055 problems with some `libc's. Thanks to Matthias Lay for reporting the
1058 2008-09-04, Version 4.5.0
1059 * collectd: Added the ability to flush certain identifiers.
1060 * collectd: The concept of `notification meta data' has been
1062 * filecount plugin: The new filecount plugin counts the number of
1063 files in a directory and its subdirectories.
1064 * ipmi plugin: Sensor names have been changed to ensure unique names.
1065 Notifications upon added and removed sensors can now be generated.
1066 * notify_desktop plugin: This new plugin sends notifications to the
1067 X desktop using the structure defined in the `Desktop Notification
1069 * notify_email plugin: This new plugin sends out notifications via
1070 email, using the `esmtp' library.
1071 * onewire plugin: The new experimental(!) onewire plugin reads values,
1072 such as temperatures, from sensors connected to the computer via the
1074 * perl plugin: Improved synchronized access to internal data structures
1075 and fixed a possible dead-lock.
1076 * perl plugin: Added the ability to flush certain identifiers and marked
1077 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1079 * perl plugin: Added the ability to configure Perl plugins.
1080 * postgresql plugin: The new postgresql plugin collects statistics
1081 about or from a PostgreSQL database.
1082 * processes plugin: The `ProcessMatch' option has been added.
1083 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1085 * tcpconns plugin: This plugin has been ported to OpenBSD.
1086 * thermal plugin: The new thermal plugin collects system temperatures
1087 using Linux ACPI thermal zone data.
1089 2009-01-02, Version 4.4.5
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 * collectd.conf(5): Various fixes and clarifications.
1097 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1098 portability problems, especially for Solaris.
1099 * dns plugin: Fix a portability problem with NetBSD.
1100 * network plugin: Fix the handling of `type' in the network protocol.
1101 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1102 much larger buffer. This caused the `type' to be transferred much
1103 more often than necessary. In some cases, e. g. the `cpu' and
1104 `cpufreq' plugins being used at the same time, data may be corrupted
1105 in those files. Thanks to Bruno Prémont for debugging and reporting
1107 * unixsock plugin: Make sure the initialization function is run only
1108 once. This resolves a file descriptor leak under systems which run
1109 the initialization more than once, such as Solaris.
1111 2008-10-16, Version 4.4.4
1112 * build system: Change `--enable-<plugin>' to abort with an error if
1113 dependencies are not met. Thanks to Bruno Prémont for the patch.
1114 Also, the poisoning of various string functions has been restricted
1116 * collectd: Fix a memory leak in the global value cache. With every
1117 *missing* value a couple of bytes would be leaked. Another memory
1118 leak in the configuration handling code has been fixed. Thanks to
1119 Niraj Tolia for reporting these issues.
1120 * collectd: Fix an off-by-one error in the ignorelist functionality.
1121 When using regular expressions, the last character would be missing,
1122 possibly matching differently from what one would expect.
1123 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1125 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1126 Linzberger for reporting the bug.

1128 code. Thanks to Niraj Tolia for reporting this issue.
1129 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1130 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1131 problems with some `libc's. Thanks to Matthias Lay for reporting the
1134 2008-09-01, Version 4.4.3
1135 * collectd: Fix a memory leak in the threshold checking code.
1136 * memcached plugin: Fix a too short timeout and a related file
1138 * memory plugin: A typo in the libstatgrab code has been fixed.
1139 * snmp plugin: Fix a possible memory leak.
1141 2008-07-15, Version 4.4.2
1142 * build system: Use pkg-config to detect the upsclient library.
1143 * collectd: Try even harder to determine the endianess of the
1144 architecture collectd is being built on.
1145 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1147 * dns plugin: Fix compilation errors with BIND versions 19991001
1149 * network plugin: Bugfix in the init routine: The init function
1150 cleared a buffer regardless of its contents. This could lead to lost
1151 values under Solaris.
1152 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1153 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1155 * wireless plugin: Work around incorrect noise and power values
1156 returned by some broken drivers.
1158 2008-06-03, Version 4.4.1
1159 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1160 to kyrone for reporting this.
1161 * collectd: Fixed min/max output in notifications generated by
1163 * collectd-nagios: Fix the protocol used to communicate with the
1165 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1166 initialization has errors. An issue with Perl 5.10 has been fixed.
1167 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1168 René Rebe and Siegmund Gorr for reporting this.
1170 2008-05-06, Version 4.4.0
1171 * collectd: Internal code cleanups.
1172 * collectd: Added support for a `Flush' command in the unixsock and
1173 exec plugins. This command can be used to force a plugin (or all) to
1174 flush its values to disk.
1175 * collectd: Thresholds can now be configured to apply to one data
1176 source only, making it possible to configure different thresholds
1177 for each data source.
1178 * apache, nginx plugins: Added the possibility to disable host and/or
1180 * ascent plugin: The new ascent plugin reads and parses the statistics
1181 page of an Ascent server.
1182 * cpu plugin: Support for the statgrab library has been added.
1183 * disk plugin: The possibility to ignore certain disks or collect only
1184 specific disks has been added.

1186 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1187 sensor values via IPMI, the intelligent platform management
1189 * iptables plugin: The iptc library that is used by the iptables
1190 plugin has been added to the distribution, because it is not
1191 provided by all distributions and removed from at least one.
1192 * powerdns plugin: The new powerdns plugin reads statistics from an
1193 authoritative or a recursing PowerDNS name server.
1194 * rrdtool plugin: The size of the files generated with the default
1195 configuration has been decreased.
1196 * tail plugin: The new tail plugin can be used to gather statistics by
1197 continuously reading from log files.
1198 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1199 TeamSpeak2 server and collects statistics about the number of users
1200 and number of channels.
1201 * users plugin: Support for the statgrab library has been added.
1202 * vmem plugin: The new vmem plugin collects very detailed statistics
1203 about the virtual memory subsystem of Linux.
1205 2008-08-30, Version 4.3.4
1206 * Build system: Improved detection of and linking with the statgrab
1208 * collectd: Portability fixes, especially to determine endianess more
1210 * Various plugins: Fix format strings.

1224 * build system: Improved detection of several libraries, especially if
1225 they are in non-standard paths.
1226 * build system: Portability fixes: Automatically define "_REENTRANT"
1227 if the libc expects it.
1228 * collectd: Error and warning messages have been improved.
1229 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1231 * apache plugin: Allocate new memory when reading a webpage instead of
1232 using a buffer of static size.
1233 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1235 * hddtemp plugin: Error and warning messages have been improved.
1236 * sensors plugin: Fix sensor collection for some chip types.
1238 2008-03-29, Version 4.3.2
1239 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1240 `Persist' threshold options.
1241 * collectd: Fix handling of missing values in the global value cache.
1242 * collectd: Improved error messages when parsing the configuration.
1243 * sensors plugin: Fix temperature collection with libsensors4.
1244 * unixsock plugin: Fix mixed input and output operation on streams.
1245 * wireless plugin: Fix reading noise value.
1247 2008-03-05, Version 4.3.1
1248 * exec plugin: Set supplementary group IDs.
1250 + Use `memcpy' when constructing/parsing a package to avoid
1251 alignment problems on weird architectures, such as Sparc.
1252 + Translate doubles to/from the x86 byte representation to ensure
1253 cross-platform compatibility.
1254 * ping plugin: Correct the handling of the `TTL' setting.
1255 * swap plugin: Reapply a patch for Solaris.
1256 * tcpconns plugin: Portability improvements.
1258 2008-02-18, Version 4.3.0
1259 * collectd: Notifications have been added to the daemon. Notifications
1260 are status messages that may be associated with a data instance.
1261 * collectd: Threshold checking has been added to the daemon. This
1262 means that you can configure threshold values for each data
1263 instance. If this threshold is exceeded a notification will be
1265 * collectd: The new `FQDNLookup' option tells the daemon to use the
1266 full qualified domain name as the hostname, not just the host part
1267 es returned by `gethostname(2)'.
1268 * collectd: Support for more than one `TypesDB' file has been added.
1269 This is useful when one such file is included in a package but one
1270 wants to add custom type definitions.
1271 * collectd: The `Include' config option has been expanded to handle
1272 entire directories and shell wildcards.
1273 * collectdmon: The new `collectdmon' binary detects when collectd
1274 terminates and automatically restarts it again.
1275 * csv plugin: The CSV plugin is now able to store counter values as a
1276 rate, using the `StoreRates' configuration option.
1277 * exec plugin: Handling of notifications has been added and the
1278 ability to pass arguments to the executed programs has been added.
1279 * hddtemp plugin: The new `TranslateDevicename' option lets you
1280 disable the translation from device names to major-minor-numbers.
1281 * logfile plugin: Handling of notifications has been added.
1282 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1283 domain name lookups in this plugin.
1284 * perl plugin: Many internal changes added support for handling multiple
1285 threads making the plugin reasonably usable inside collectd. The API has
1286 been extended to support notifications and export global variables to
1287 Perl plugins; callbacks now have to be identified by name rather than a
1288 pointer to a subroutine. The plugin is no longer experimental.
1289 * uuid plugin: The new UUID plugin sets the hostname to an unique
1290 identifier for this host. This is meant for setups where each client
1291 may migrate to another physical host, possibly going through one or
1292 more name changes in the process. Thanks to Richard Jones from
1293 Red Hat's Emerging Technology group for this plugin.
1294 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1295 CPU, disk and network statistics about guest systems on the same
1296 physical server. Thanks to Richard Jones from Red Hat's Emerging
1297 Technology group for this plugin.
1299 2008-04-22, Version 4.2.7
1300 * build system: Improved detection of several libraries, especially if
1301 they are in non-standard paths.
1302 * build system: Portability fixes: Automatically define "_REENTRANT"
1303 if the libc expects it.
1304 * collectd: Error and warning messages have been improved.
1305 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1307 * apache plugin: Allocate new memory when reading a webpage instead of
1308 using a buffer of static size.
1309 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1311 * hddtemp plugin: Error and warning messages have been improved.
1312 * sensors plugin: Fix sensor collection for some chip types.

1317 * unixsock plugin: Fix mixed input and output operation on streams.
1318 * wireless plugin: Fix reading noise value.
1320 2008-03-04, Version 4.2.5
1321 * apache plugin: Improved initialization and error messages.
1322 * exec plugin: Set supplementary group IDs.
1324 + Create separate threads for reading from the socket and parsing
1325 and dispatching incoming packets. Versions prior to this may have
1326 problems in high-load situations, where the socket receive buffers
1327 overflows, resulting in gaps in the data.
1328 + Use `memcpy' when constructing/parsing a package to avoid
1329 alignment problems on weird architectures, such as Sparc.
1330 + Translate doubles to/from the x86 byte representation to ensure
1331 cross-platform compatibility.
1332 * ping plugin: Correct the handling of the `TTL' setting.
1333 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1334 * swap plugin: Reapply a patch for Solaris.
1335 * tcpconns plugin: Portability improvements.
1337 2008-01-21, Version 4.2.4
1338 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1339 the permission on the socket as documented in the manpage. Thanks to
1340 Evgeny Chukreev for fixing this issue.
1341 * collectd: The documentation has been improved.
1343 2007-12-28, Version 4.2.3
1344 * sensors plugin: Updated the plugin to build and work with version 3
1345 of the libsensors library.
1347 2007-12-15, Version 4.2.2
1348 * nginx plugin: Incorrect comparison of strings lead to a segfault
1349 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1351 * logfile plugin: The config option `Timestamp' was handled
1352 incorrectly and basically always active. Thanks to Luke Heberling
1355 2007-11-08, Version 4.2.1
1356 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1357 enabled on the host.
1358 * snmp plugin: Fix a memory leak.
1360 2007-10-27, Version 4.2.0
1361 * collectd: The new config option `Include' lets you include other
1362 configfiles and thus split up your config into smaller parts. This
1363 may be especially interesting for the snmp plugin to keep the data
1364 definitions separate from the host definitions.
1365 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1366 (number of connections, octets and packets for each service and
1367 destination). Thanks to Sebastian Harl for this plugin.
1368 * memcached plugin: The new `memcached' plugin connects to a memcached
1369 daemon process and collects statistics of this distributed caching
1370 system. Thanks to Antony Dovgal for contributing this plugin.
1371 * nginx plugin: The new `nginx' plugin reads the status page of an
1372 nginx daemon and saves the handled connections and requests.
1373 * perl plugin: Many changes, including the added `EnableDebugger'
1374 config option which lets you debug your Perl plugins more easily.
1375 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1376 be more thread-safe otherwise by locking calls to the library.
1377 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1378 correct the values returned by SNMP-agents. If a <data> block is
1379 defined as `table' the instance is now optional. The sequence number
1380 is used as the type-instance in this case. The new `InstancePrefix'
1381 option allows to add arbitrary prefixes to the type-instance.
1382 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1383 certain TCP connections and what state they're in. This can be used
1384 to see how many connections your FTP server has to handle or how
1385 many outgoing connections your mailserver has open.
1387 2008-01-11, Version 4.1.6
1388 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1389 the permission on the socket as documented in the manpage. Thanks to
1390 Evgeny Chukreev for fixing this issue.

1397 of the libsensors library.
1399 2007-11-08, Version 4.1.4
1400 * Build system: Improve detection of the rrd library, especially if
1401 it's in a non-standard location.
1402 * Build system: A bug when parsing the argument for
1403 `--with-libnetsnmp' has been fixed.
1404 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1405 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1406 a deadlock or delay when shutting down the daemon.
1407 * snmp plugin: Fix a memory leak.
1409 2007-10-24, Version 4.1.3
1410 * collectd: A build issue under Solaris has been resolved by renaming
1412 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1413 be more thread-safe otherwise by locking calls to the library.
1415 2007-09-28, Version 4.1.2
1416 * apcups plugin: Fix reporting of the `load percent' data.
1417 * wireless plugin: Correct the handling of cards returning signal and
1418 noise quality as percentage.
1419 * perl plugin: Fix a possible buffer overflow in get_module_name().
1420 * build system: Further improve the detection of libraries.
1421 * netlink plugin: Build issues under some older versions of the Linux
1422 includes (i. e. Debian Sarge) have been fixed.
1423 * snmp plugin: Fix a potential segfault when a host times out. Add
1424 support for the `timeticks' type.
1426 2007-09-12, Version 4.1.1
1427 * Build system: The detection of `libnetlink' has been improved.
1428 * collectd: The documentation has been fixed in numerous places.
1429 * exec plugin: Setting the group under which to run a program has been
1431 * collectd: The `sstrerror' function was improved to work correctly
1432 with the broken GNU version of `strerror_r'.
1433 * collectd: Write an error message to STDERR when loading of a plugin
1435 * apcups plugin: Fix the `types' used to submit the values: They still
1436 has an `apcups_' prefix which doesn't work anymore.
1437 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1438 whatever the client thinks is `now'..
1440 2007-09-01, Version 4.1.0
1441 * Build system: The build system has been changed to automatically
1442 disable all plugins, which are missing dependencies. The dependency
1443 checking has been removed from the plugins themselves to remove
1445 * Flexible interval: The interval of collected data is now sent along
1446 with the data itself over the network, so that the interval-settings
1447 of server and clients no longer needs to match.
1448 * netlink plugin: The new `netlink' plugin connects to the Linux
1449 kernel using a netlink socket and uses it to query information about
1450 interfaces, qdiscs and classes.
1451 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1452 to not block data collection.
1453 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1454 network devices, such as switches, routers, thermometers, rack
1455 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1457 * unixsock plugin: Added the `LISTVAL' command.
1458 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1459 of music played with xmms.
1461 2007-09-28, Version 4.0.9
1462 * apcups plugin: Fix reporting of the `load percent' data.
1463 * wireless plugin: Correct the handling of cards returning signal and
1464 noise quality as percentage.
1465 * perl plugin: Fix a possible buffer overflow in get_module_name().
1467 2007-09-12, Version 4.0.8
1468 * collectd: The `sstrerror' function was improved to work correctly
1469 with the broken GNU version of `strerror_r'.
1470 * collectd: Write an error message to STDERR when loading of a plugin
1472 * apcups plugin: Fix the `types' used to submit the values: They still
1473 has an `apcups_' prefix which doesn't work anymore.
1474 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1475 whatever the client thinks is `now'..
1477 2007-08-26, Version 4.0.7
1478 * documentation: Some typos have been fixed and some information has
1480 * build system: Many fixes for detecting libraries in unusual places,
1481 such as on RedHat systems. The affected libraries are `libcurl',
1482 `libmysql', and `libupsclient'.
1483 * network plugin: Allow the `Port' option to be specified as a number
1484 (i. e. without quotes).
1485 * nut plugin: A fix allows linking the nut plugin against
1486 libupsclient, version >= 2.2.0.
1487 * processes plugin: Fix a potential segmentation fault.
1489 2007-07-30, Version 4.0.6
1490 * sensors plugin: Fix the ignorelist functionality: Only the `type
1491 instance' was used to match against the list, but the documentation
1492 told otherwise. This release fixes the code, so it complies with the
1494 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1495 configuration messages will end up in the logging facility.
1496 * conrtib/fedora: The contributed specfile for Fedora has been
1499 2007-07-05, Version 4.0.5
1500 * Portability: More fixes for OpenBSD have been included.
1502 2007-06-24, Version 4.0.4
1503 * cpu plugin: Fixed the Solaris code.
1504 * dns plugin: Fixed a build issue for OpenBSD.
1505 * interface plugin: Fixed the Solaris code.
1506 * load plugin: Fixed the alternative `/proc' Linux code.
1507 * memory plugin: Fixed the Solaris code.
1508 * oconfig: Don't require `-lfl' anymore.
1510 2007-06-19, Version 4.0.3
1511 * cpu plugin: Fix the Darwin / Mac OS X code.
1512 * ping plugin: Use the return value of `getpid', not its address.
1513 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1514 initialized correctly.
1515 * configure: Added `--with-nan-emulation' to aid cross compilation.
1517 2007-06-12, Version 4.0.2

1519 they're given in numerically form.
1521 2007-06-07, Version 4.0.1
1522 * iptables plugin: A bug in the configuration routine has been fixed.
1523 Setting a comment in the configfile will no longer cause a
1526 2007-06-03, Version 4.0.0
1527 * collectd: The plugin-infrastructure has been changed to allow for
1528 more types of plugins, namely `write' and `log' plugins.
1529 * collectd: The read-function has been changed to read many plugins in
1530 parallel, using threads. Thus, plugins generally need to use
1531 thread-safe functions from now on.
1532 * collectd: The '-t' command line options allows to perform syntax tests
1533 of the configuration file and exit immediately.
1534 * csv plugin: The new `csv' plugin handles output to `comma separated
1536 * rrdtool plugin: The new `rrdtool' plugin handles output to
1537 RRD-files. Data can be cached to combine multiple updates into one
1538 write to increase IO-performance.
1539 * network plugin: The new `network' plugin handles IO via the network.
1540 It implements a different, much more extensible protocol which can
1541 combine many values in one packet, decreasing the number of UDP-
1542 packets being sent. It can read from and send to the network and
1543 with the appropriate configuration even forward packets to other
1545 * unixsock plugin: The new `unixsock' plugin provides an interface to
1546 communicate with the daemon while it is running. Right now the
1547 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1549 * perl plugin: The new `perl' plugin allows you to write extensions
1550 for collectd in the scripting-language Perl.
1551 * logfile plugin: The new `logfile' plugin writes logmessages to files
1552 or STDOUT or STDERR.
1553 * syslog plugin: The new `syslog' plugin sends logmessages to the
1554 system's syslog daemon.
1555 * entropy plugin: The new `entropy' plugin collects the amount of
1556 entropy currently being available to the system.
1557 * exec plugin: The new `exec' plugin forks child processes and reads
1558 back values provided by the forked processes.
1559 * iptables plugin: The new `iptables' plugin reads counters from
1560 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1562 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1563 to Peter Holik for contributing this plugin.
1564 * nut plugin: The new `nut' plugin connects the upsd of the `network
1565 ups tools' and reads information about the connected UPS.
1566 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1567 connections) field was added by Florent Monbillard.
1568 * collectd-nagios: The new `collectd-nagios' binary queries values
1569 from collectd, parses them and exits according to Nagios-standards.
1570 * manpages: The manpages have been improved a lot.
1572 2007-09-28, Version 3.11.7
1573 * wireless plugin: Correct the handling of cards returning signal and
1574 noise quality as percentage.
1576 2007-08-31, Version 3.11.6
1577 * processes plugin: Fix a potential segmentation fault.
1579 2007-05-29, Version 3.11.5
1580 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1581 * ntpd plugin: Fix a potential buffer overflow.
1582 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1583 were accounted as `zombies'.
1585 2007-04-10, Version 3.11.4
1586 * dns plugin: Change the order of includes to make the plugin compile
1589 2007-03-30, Version 3.11.3
1590 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1591 of the unused `COLLECT_KSTAT'.
1593 2007-02-11, Version 3.11.2
1594 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1595 NULL-pointer may have been passed to `printf' which causes a
1596 segfault with some libcs.
1598 2007-02-10, Version 3.11.1
1599 * df plugin: Some wrong defines have been fixed so the plugin works
1600 under Solaris again.
1601 * dns plugin: The usage of a struct has been fixed to work with
1603 * processes plugin: Some missing defines have been added so the plugin
1604 compiles cleanly under FreeBSD and presumably other UNIXes.
1606 2006-12-22, Version 3.11.0
1607 * collectd: The new command line option `-P' makes it easier for
1608 distributors to change the location of PID-files.
1609 * collectd: The daemon shuts down faster now which makes it easier to
1610 write init.d-scripts for it.
1611 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1612 caused problems every now and then.
1613 * df plugin: New config options allow to ignore certain mountpoints,
1614 filesystem types or devices.
1615 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1616 and interprets it. It collects traffic as well as qtype, opcode and
1618 * email plugin: Sebastian Harl has contributed this plugin which
1619 counts received mails in categories (e. g. ham, spam, virus), spam
1620 score (as given by SpamAssassin) and check types.
1621 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1622 uses `mbmon' to gather information from sensors on the motherboard.
1623 * processes plugin: Collect detailed statistics for configured
1624 processes, that's process and thread count, CPU usage, resident
1625 segment size and pagefaults.
1626 * multimeter plugin: Peter Holik contributed a new plugin which
1627 queries multimeters.
1628 * sensors plugin: Lubos Stanek has put much effort into improving this
1629 plugin, including `extended naming', collection of voltage values
1630 and the possibility to ignore certain values.
1632 2006-12-21, Version 3.10.4
1633 * Max Kellermann has identified a bug in the server routine: When
1634 opening a socket fails the daemon will (re)try opening the socket in
1635 an endless loop, ultimately leading to a `EMFILE' error.
1637 2006-11-04, Version 3.10.3
1638 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1639 ntpd's reply was sent in more than one packet, the buffer size was
1640 calculated incorrectly, resulting in the reading of uninitialized or
1643 2006-11-01, Version 3.10.2
1644 * The sample config file has been improved.
1645 * Errors in the manpages have been corrected.
1646 * The ping-plugin now adds hosts during initialization, not during
1647 startup. This speeds up startup when no network connectivity is
1648 available. Also, the hosts are being added later when the network is
1650 * Improved BSD-support for the df-plugin.
1651 * Fixed syntax errors in the swap-plugin for Mac OS X.
1652 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1654 * Don't disable the mysql-plugin if connecting to the database fails
1655 during initialization. Instead, try again in increasing intervals.
1657 2006-07-19, Version 3.10.1
1658 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1659 the apcups cannot be reached, unconnected sockets will pile up and
1660 eventually lead to `Too many open files' errors.
1662 2006-07-09, Version 3.10.0
1663 * The `disk' plugin has been ported to Darwin.
1664 * The `battery' plugin should work on many Apple computers now.
1665 * The `traffic' plugin can now ignore certain interfaces. Also,
1666 statistics for sent/received packets and errors have been added.
1667 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1668 to Anthony Gialluca for contributing this plugin and providing me
1669 with a test environment :)
1670 * A plugin for monitoring an NTP instance and the local clock drift
1673 2006-06-25, Version 3.9.4
1674 * The Solaris code in the `swap' plugin has been changed to reflect
1675 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1677 * The debugging system has been fixed to work with the Sun libc.
1678 * When built without librrd the variable `operating_mode' could be
1679 uninitialized. Thanks to David Elliot for reporting the bug.
1681 2006-06-01, Version 3.9.3
1682 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1683 operating systems also profit from the changes, but I wasn't able to
1685 * Changed the build system to find the netinet-includes under FreeBSD
1686 and therefore successfully build the `liboping' library there.
1688 2006-05-09, Version 3.9.2
1689 * Applied a patch to the `liboping' library. Due to a bug in the
1690 sequence checking the `ping' plugin stopped working after
1691 approximately 7.6 days.
1693 2006-05-09, Version 3.8.5
1694 * Applied a patch to the `liboping' library. Due to a bug in the
1695 sequence checking the `ping' plugin stopped working after
1696 approximately 7.6 days.
1698 2006-04-21, Version 3.9.1
1699 * Build issues with Solaris and possible other architectures have been
1701 * Problems when building the `apache'-plugin without `libcurl' have
1703 * A bug in the `ping' plugin has been fixed. Sorry folks.
1705 2006-04-02, Version 3.9.0
1706 * A plugin to monitor the Apache webserver has been added.
1707 <http://httpd.apache.org/>
1708 * A plugin to collect statistics about virtual servers using VServer.
1709 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1711 * A plugin for wireless LAN cards has been added. It monitors signal
1712 strength, link quality and noise ratio..
1713 * A plugin for Apple hardware sensors has been added.
1714 * An option to compile collectd with different `step' and `heartbeat'
1715 settings has been added. The size of RRAs is no longer static but
1716 calculated based on the settings for `step' and `width'.
1717 * The `ping' plugin can now be configured to use a certain TTL.
1718 * A plugin to monitor the hardware sensors of Apple computers has been
1720 * The plugins `cpu', `memory', `processes' and `traffic' have been
1721 ported to Mach/Darwin (Mac OS X).
1722 * The `log mode' has been contributed by Christophe Kalt. It writes
1723 the data into text files rather than RRD files.
1725 2006-04-09, Version 3.8.4
1726 * Applied patch by Vincent Stehlé which improves the disk-name
1727 resolution in the `hddtemp' plugin for Linux systems.
1729 2006-04-02, Version 3.8.3
1730 * Applied a patch by James Byers: The MySQL plugin was not working
1731 with MySQL 5.0.2 or later.
1733 2006-03-14, Version 3.8.2
1734 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1735 the GNU libc, because it points to `/etc/fstab' rather than
1738 2006-03-13, Version 3.8.1
1739 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1740 * Fixes in the debian `postinst' and `init.d' scripts.
1742 2006-03-09, Version 3.8.0
1743 * The `ping' plugin no longer uses `libping' but a self written
1744 library named `liboping'. With this library it's possible to ping
1745 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1747 2006-02-18, Version 3.7.2
1748 * A simple bug in the `battery' plugin has been fixed. It should now
1749 work with ACPI based batteries as well. Thanks to Sebastian for
1751 * Fixing a bug that prevented collectd to be built without librrd.
1752 Thanks to Werner Heuser for reporting it.
1754 2006-02-04, Version 3.7.1
1755 * The new network code has been improved to build with older versions
1757 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1758 to Tommie Gannert for this patch.
1760 2006-01-30, Version 3.7.0
1761 * The `battery' plugin has been added. It collects information about
1763 * The MySQL plugin has been improved: It now writes two more RRD
1764 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1765 * The `cpufreq' plugin now reads another file since the file it did
1766 read so far causes much overhead in the kernel. Also, you need root
1767 to read the old file, but not to read the new one.
1768 * The `hddtemp' plugin can now be configured to connect to another
1769 address and/or port than localhost.
1770 * The `df' plugin now prefers `statvfs' over `statfs'.
1771 * The network code has been rewritten. collectd now supports unicast
1772 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1773 be set in the configfile.
1775 2006-01-24, Version 3.6.2
1776 * Due to a bug in the configfile handling collectd wouldn't start in
1777 client mode. This released fixes this.
1779 2006-01-20, Version 3.6.1
1780 * Due to a bug in `configure.in' all modules and the binary were
1781 linked against `libmysqlclient'. This issue is solved by this
1784 2006-01-17, Version 3.6.0
1785 * A config file has been added. This allows for loading only specific
1787 * A `df' plugin has been added.
1788 * A `mysql' plugin has been added.
1789 * The `ping' plugin doesn't entirely give up hope when a socket error
1790 occurred, but will back of and increase the intervals between tries.
1792 2006-01-21, Version 3.5.2
1793 * Fixed yet another bug in the signal handling.. Stupid typo..
1794 * Improved the ping plugin to not give up on socket errors (backport
1797 2005-12-18, Version 3.5.1
1798 * The PID-file is now deleted correctly when shutting down the daemon.
1799 * SIGINT and SIGTERM are now handled correctly.
1801 2005-12-16, Version 3.5.0 (Revision 326)
1802 * A bug in the `load' module under Solaris has been fixed.
1803 * The `users' module has been contributed by Sebastian Harl. It counts
1804 currently logged in users.
1805 * The CPU module now works under FreeBSD without the use of
1806 `libstatgrab', however SMP support is missing.
1807 * The default directories for the RRD files and the PID file now
1808 depend on the compile time setting of `localstatedir'.
1810 2005-11-15, Version 3.4.0 (Revision 236)
1811 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1812 from gentoo's bugzilla for writing the patch.
1813 * The build dependency for librrd has been removed. Binaries built
1814 without librrd are client-only and will multicast their value as
1815 with the `-c' argument.
1816 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1817 * The newly introduced `-f' switch prevents daemon initialization
1818 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1819 Barcellos for this patch.
1821 2005-11-04, Version 3.3.0 (Revision 216)
1822 * New modules have been added:
1823 - `serial', for monitoring traffic on the serial interfaces
1824 - `nfs', for graphing NFS procedure calls
1825 - `tape', traffic from/to tape devices
1826 * The memory.rrd now accepts more than 4Gig of memory.
1828 2005-10-26, Version 3.2.0 (Revision 200)
1829 * Support for graphing the processes has been added (thanks to Lyonel
1831 * If reading from hddtemp fails collectd will increase the time
1832 between polls up to one day.
1833 * The init.d files have been improved.
1834 * Problems with the spec file have been fixed.
1836 2005-10-16, Version 3.1.0 (Revision 194)
1837 * Added the `setsid' syscall to the startup code.
1838 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1840 2005-09-30, Version 3.0.0 (Revision 184)
1841 * The ability to send/receive data to/from the network (think
1842 multicast) has been added.
1843 * Modules have been split up into shared libraries can be loaded at
1844 runtime. The biggest advantage is that the core program doesn't need
1845 to be linked against an external library.
1846 * A patch by George Kargiotakis has been applied: It fixes the sensors
1847 behaviour then more than one sensor is being queried.
1849 2005-09-16, Version 2.1.0 (Revision 172)
1850 * A module for swap statistics has been added.
1852 2005-09-09, Version 2.0.0 (Revision 135)
1853 * Filenames can no longer be configured at program startup. The only
1854 options as of this version are the directory and ping hosts.
1855 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1856 Soft-IRQ statistics are added to `System'.
1857 * Diskstats now collect read and write bytes, not sectors.
1858 * Ping statistics can now be collected for more than one host. There
1859 is no default any more: If no host is given no host will be pinged.
1860 * A self-written patch for libping has been applied so it builds
1863 2005-09-01, Version 1.8.1 (Revision 123)
1864 * Much improved configure-script: libraries and features may now be
1866 * More detailed warnings/error messages when RRD update fails.
1868 2005-08-29, Version 1.8.0:
1869 * Support for collecting disk statistics under Solaris.
1871 2005-08-25, Version 1.7.0:
1872 * Support for libstatgrab[1] for load, memory usage and network
1873 traffic. CPU- and disk-usage are not (yet) supported, since
1874 libstatgrab returns insufficient information. I will contact the
1876 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1877 aren't necessarily counted linear which is now handled correctly.
1878 [1]: http://www.i-scream.org/libstatgrab/
1880 2005-08-21, Version 1.6.0:
1881 * Basic support for Solaris: System load and cpu-usage can be
1882 collected under Solaris, too. Other stats will follow later.
1883 * Many fixes in the autoconf-script
1884 * Collection/Museum scripts have been added under contrib/museum
1885 * collectd may now be started in unprivileged mode, though ping
1886 statistics will not work.
1888 2005-07-17, Version 1.5.1:
1889 * Diskstats-RRDs now use major/minor for naming. Some systems have
1890 weird strings as disk-names..
1892 2005-07-17, Version 1.5:
1893 * A new module, diskstats, has been added. It collects information
1894 about the disks and partitions.
1896 2005-07-11, Version 1.4.2:
1897 * The meminfo module has been changed to work with more platforms
1898 and/or kernel versions.
1900 2005-07-10, Version 1.4.1: Correct traffic stats
1901 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1902 forgot to correct when I changed that module.
1904 2005-07-09, Version 1.4: More traffic stats
1905 * Traffic is now collected for all interfaces that can be found
1906 * Temperature-statistics are read from lm-sensors if available
1908 2005-07-08, Version 1.3: CPU stats
1909 * Collecting CPU statistics now
1911 2005-07-12, Version 1.2: Using syslog
1912 * collectd is now using the syslog facility to report errors, warnings
1914 * The default directory is now /var/db/collectd
1916 2005-07-10, Version 1.1: Minor changes
1917 * Nothing really useful to say ;)
1919 2005-07-09, Version 1.0: Initial Version
1920 * The following modules are provided:
