940 collected by collectd to a web-server using HTTP POST requests.
941 Thanks to Paul Sadauskas for the patch.
942 * zfs_arc plugin: The new ZFS ARC plugin collects information about
943 the “Adaptive Replacement Cache” (ARC) of the “Zeta File-System”
944 (ZFS). Thanks to Anthony Dewhurst for the patch.
945 * empty_counter match: The new Empty Counter match matches value
946 lists, where at least one data source is of type COUNTER and the
947 counter value of all counter data sources is zero.
949 2009-12-18, Version 4.7.5
950 * Build system, java plugin: Don't use “find -L” to search for Java
951 headers, because it's a GNU extension.
952 * Build system: Support for parallel builds has been improved. Thanks
953 Sebastian Harl and Stefan Völkel for looking into this.
954 * collectd: Print error messages to STDERR if no log plugin has been
955 loaded.
956 * memory plugin: Handling of >4 Gbyte of memory has been fixed.
957 * network plugin: The license has been changed to LGPL 2.1.

964 fixed. Thanks to Ben Knight for his patch.
966 2009-10-03, Version 4.7.4
967 * Build system: Issues when building the iptables plugin have been
968 fixed.
969 * exec plugin: Clear the signal block mask before calling exec(2).

971 issues on some platforms.
972 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
973 Andrés J. Díaz for the patch.
974 * unixsock plugin: Fix a (well hidden) race condition related to file
975 descriptor handling.
977 2009-09-13, Version 4.7.3
978 * collectd: Fix a possible but very rare invalid “free” in the caching
979 code. Thanks to Sebastian Harl for the patch.
980 * collectd: Remove old values when a cache entry is marked as missing.
981 This way the “GETVAL” command of the UnixSock plugin doesn't return
982 old, no longer valid values when this happens. Thanks to Andrés J.
983 Díaz for the patch.
984 * collectd: The “plugin_unregister_read” function has been fixed.
985 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
986 to follow redirects. Thanks to Joey Hess for reporting this bug.

988 possibly reducing the number of stats considerably. Thanks to Joey
989 Hess for reporting this bug.
990 * iptables plugin: Support for the new libiptc API has been added.
991 Thanks to Sebastian Harl for the patch. The build system has been
992 updated to the plugin only includes the shipped header files when it
993 is linked with the shipped library, too.
994 * java plugin: Delay creating the JVM until after the daemon has
995 forked. The JVM internally creates threads that are lost when
996 forking. This means that Java-based plugins are now configured
997 during the init-phase, i. e. later than other plugins.
998 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
999 to Alan Pevec for the patch.
1000 * network plugin: Fix the handling of the “CacheFlush” option: The
1001 value was assigned to a wrong variable. The initialization of the
1002 gcrypt library, which is used for signing / encrypting traffic, has
1003 been fixed. Thanks to Luke Heberling for the patch.
1004 * powerdns plugin: Set a timeout when reading data from the datagram
1005 socket. Handling of the “LocalSocket” option has been fixed. An
1006 incorrectly used “type” has been corrected. Thanks to Luke Heberling
1007 for his patches.

1022 details have been added to the configuration summary. Support for
1023 libtool 2.2 has been added.
1024 * collectd: Two bugs with the threshold checking have been fixed. The
1025 first one prevented thresholds to be checked at all, the second one
1026 caused wrong behavior with the persistency option. Thanks to Andrés
1027 J. Díaz for fixing these problems.
1028 * collectd: Handling of the `Include' configuration option has been
1029 fixed.
1030 * rrdtool plugin: Make sure initialization is run only once. This
1031 resolves problems under Solaris and potentially other systems.
1032 Thanks to Amit Gupta for reporting this bug.
1033 * java plugin: Make it possible to use dots ('.') instead of slashes
1034 ('/') as the class separator. Thanks to Randy Rizun for pointing
1035 this out.
1036 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1037 to Doug MacEachern for the patch.

1050 multicast traffic from Ganglia's gmond daemon.
1051 * java plugin: The new java plugin exports the collectd API to Java,
1052 making it possible to write extensions to collectd in Java.
1053 * memcachec plugin: The new memcachec plugin queries data from a
1054 memcached daemon and parses it similar to the cURL plugin. Thanks to
1055 Doug MacEachern for the initial code.
1056 * memcached plugin: Support for connections over UNIX domain sockets
1057 has been added. Thanks to Franck Lombardi for the patch.
1058 * memory plugin: Support for OpenBSD and possibly other *BSDs has been
1059 added. Thanks to Simon Kuhnle for the patch.
1060 * mysql plugin: Support to query multiple databases has been added.
1061 Thanks to Doug MacEachern for the patch.
1062 * mysql plugin: Master/slave statistics have been added.
1063 * mysql plugin: Lock statistics have been added. Thanks to Rodolphe
1064 Quiédeville for the patch.
1065 * network plugin: The possibility to sign or encrypt network traffic
1066 has been added.
1067 * protocols plugin: The new protocols plugin provides information
1068 about network protocols, such as IP, TCP and UDP.
1069 * snmp plugin: The intervals given in the configuration of the SNMP
1070 plugin must no longer be a multiple of the global interval.
1071 * table plugin: The new Table plugin provides parsing for table-like
1072 structured files, such as many files beneath /proc.
1073 * ted plugin: The new TED plugin reads power consumption measurements
1074 from “The Energy Detective” (TED). Thanks to Eric Reed for this
1075 plugin.
1076 * onewire plugin: The new `Interval' option allows collecting
1077 information from OneWire sensors at arbitrary intervals.
1078 * ping plugin: Support for collecting the drop rate and standard
1079 deviation of round-trip times has been added.
1080 * uptime plugin: The new uptime plugin can collect the server's
1081 uptime. Thanks to Marco Chiappero for the patch.
1083 2009-09-10, Version 4.6.5
1084 * collectd: Remove old values when a cache entry is marked as missing.
1085 This way the “GETVAL” command of the UnixSock plugin doesn't return
1086 old, no longer valid values when this happens. Thanks to Andrés J.
1087 Díaz for the patch.
1088 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1089 to follow redirects. Thanks to Joey Hess for reporting this bug.
1090 * df plugin: Check the ignorelist before stating the file system,
1091 possibly reducing the number of stats considerably. Thanks to Joey
1092 Hess for reporting this bug.
1093 * iptables plugin: Support for the new libiptc API has been added.
1094 Thanks to Sebastian Harl for the patch. The build system has been

1110 for reporting the bug.
1112 2009-06-02, Version 4.6.3
1113 * Build system, various plugins: Many build fixes for FreeBSD,
1114 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1115 for many fixes and providing a build system for many platforms,
1116 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1117 providing an OpenBSD system.
1118 * collectd: Two bugs with the threshold checking have been fixed. The
1119 first one prevented thresholds to be checked at all, the second one
1120 caused wrong behavior with the persistency option. Thanks to Andrés
1121 J. Díaz for fixing these problems.
1122 * collectd: Handling of the `Include' configuration option has been
1123 fixed.
1124 * battery plugin: Don't complain about a missing directory every
1125 interval.
1126 * exec plugin: Allow executed programs to close STDERR. Thanks to
1127 Thorsten von Eicken for reporting this problem.
1128 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1129 Tomasz Pala for the patch.
1130 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1131 the patch.
1132 * memory plugin: Fix a potential problem under Solaris.
1133 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1134 to Doug MacEachern for the patch.
1136 2009-03-18, Version 4.6.2
1137 * collectd: Some Solaris utility code has been improved.
1138 * filter subsystem: Allow `Chains' without default targets.
1139 * liboping: A patch to comply with strict aliasing rules has been
1140 added.
1141 * timediff match: Fix a typo: The match was registered with a wrong
1142 name which prevented this match to be used as documented. Thanks to
1143 Bruno Prémont for finding this problem.
1144 * bind plugin: Fix collection of the cached RR sets. The number of RR
1145 sets currently in the cache was collected as a counter value, which
1146 is nonsense. Thanks to Bruno Prémont for implementing this.
1147 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1148 primarily BSDs, don't take it well and crash.
1149 * oracle plugin: Portability to 64 bit systems has been improved.
1150 * postgresql plugin: The default configuration has been improved.
1151 * rrdtool plugin: Fix a possible race condition: If the network plugin
1152 is brought and dispatches a value before the rrdtool plugin is
1153 initialized, the daemon may crash.
1155 2009-02-22, Version 4.6.1
1156 * collectd: Many documentation fixes.
1157 * Collectd::Unixsock: Error handling has been improved.
1158 * regex match: Don't link with the PCRE library.
1159 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1160 for finding and fixing most of them.
1161 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1162 faults. Thanks to Peter Holik for his patch.
1164 2009-02-16, Version 4.6.0
1165 * collectd: Added the `filter chain' infrastructure, which allows the
1166 user to use `matches' and `targets' to control value processing.
1167 * collectd: The new `-T' command line argument allows more in-depth
1168 testing of a configuration. Thanks to Doug MacEachern for the patch.
1169 * collectd-nagios: The Nagios integration command has been updated to
1170 use libcollectdclient. The `percentage' aggregation function has
1171 been added. Thanks to Fabian Linzberger for the patch.
1172 * libcollectdclient: A library which abstracts communication with the
1173 unixsock plugin for clients has been added.
1174 * regex match: Match values by their identifies using regular
1175 expressions.
1176 * timediff match: Match for values with an invalid timestamp.
1177 * value match: Select values by their data sources' values.
1178 * notification target: Create and dispatch a notification.
1179 * replace target: Replace parts of an identifier using regular
1180 expressions.
1181 * set target: Set (overwrite) entire parts of an identifier.
1182 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1183 statistics, allowing very detailed name server statistics. Thanks to
1184 Bruno Prémont for this plugin.
1185 * cpu plugin: Report `interrupt' separately when using
1186 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1187 example for native OpenBSD support, has been added. Thanks to Simon
1188 Kuhnle for the patch.
1189 * csv plugin: Make it possible to write values to STDOUT instead of
1190 files. This is meant for testing purposes mostly. The output written
1191 to STDOUT is compatible with the exec plugin. Thanks to Doug
1192 MacEachern for the patch.
1193 * curl plugin: This new plugin can be used to read web pages and parse
1194 them using the same mechanism that's used in the tail plugin.
1195 * dbi plugin: This new plugin allows you to connect to a variety of
1196 relational databases and use SQL to gather custom statistics from
1197 it. It is similar to the already existing PostgreSQL plugin but uses
1198 libdbi to communicate with the database(s).
1199 * interface plugin: Use the ignorelist framework when selecting /
1200 ignoring interfaces. This allows one to use regular expressions to
1201 select interfaces, too.
1202 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1203 Thanks to Bruno Prémont for this patch.
1204 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1205 for the patch.

1207 socket, too. Thanks to Mirko Buffoni for the patch.
1208 * network plugin: Further performance improvements for the receive
1209 code. This hopefully will help very large setups.
1210 * openvpn plugin: This new plugin collects statistics provided by the
1211 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1212 * oracle plugin: This new plugin allows you to connect to an Oracle
1213 database and use SQL to gather custom statistics from it. It is
1214 similar to the already existing PostgreSQL plugin.
1215 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1216 have been added.
1217 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1218 * perl plugin: Added support for `notification meta data'.
1219 * perl plugin: Added support for the `filter chain' infrastructure by
1220 allowing plugins to register `matches' and `targets'.
1221 * postgresql plugin: The preferred configuration syntax has been
1222 updated to be in line with the syntax used by the new dbi and oracle
1223 plugins. The compatibility code for the old syntax is present.
1224 Support for the new `Result' blocks and the interval parameter has
1225 been added.
1226 * processes plugin: Stacksize and virtual memory usage statistics have
1227 been added. Portability fixes.
1228 * rrdcached plugin: This new plugin uses the (still in development)
1229 RRD accelerator daemon, rrdcached. This daemon works very similar to
1230 the original rrdtool plugin of collectd, but adds some more nice
1231 features.
1232 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1233 added.
1235 2009-05-09, Version 4.5.4
1236 * Build system, various plugins: Many build fixes for FreeBSD,
1237 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1238 for many fixes and providing a build system for many platforms,
1239 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1240 providing an OpenBSD system.
1241 * collectd: Fix a potential race condition when creating directories.
1242 * battery plugin: Don't complain about a missing directory every
1243 interval.
1244 * dns plugin: Slight portability fixes.
1245 * exec plugin: Allow executed programs to close STDERR. Thanks to
1246 Thorsten von Eicken for reporting this problem.
1247 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1248 Tomasz Pala for the patch.
1249 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1250 the patch.
1251 * rrdtool plugin: Fix a possible race condition: If the network plugin
1252 is initialized and dispatches a value before the rrdtool plugin is
1253 initialized, the daemon may crash.
1254 * memory plugin: Fix a potential problem under Solaris.
1256 2009-02-22, Version 4.5.3
1257 * build system: The check for libupsclient even when `pkg-config' is
1258 not available.
1259 * collectd: Fix error handling in the global cache.
1260 * Collectd::Unixsock: Error handling has been improved.
1261 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1262 patch.
1263 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1264 faults. Thanks to Peter Holik for his patch.
1265 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1266 code. Thanks to "thated" for reporting this.
1268 2009-01-02, Version 4.5.2
1269 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1270 file may be in both locations, especially when the database was
1271 installed in a non-standard path. Thanks to Dusty Doris for
1272 reporting this.
1273 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1274 Solaris, in the configure script automatically.
1275 * build system, tcpconns plugin: Check for `kvm_nlist' and
1276 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1277 library with similar functions to the BSD variant, but doesn't
1278 provide these necessary functions.
1279 * collectd.conf(5): Various fixes and clarifications.
1280 * collectd: Remove a GNUism (unnamed unions), thus improving
1281 portability.
1282 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1283 This solves portability problems, especially for Solaris.
1284 * dns plugin: Fix a portability problem with NetBSD.
1285 * filecount plugin: Fix an off-by-one error. This error may cause a
1286 segmentation fault.
1287 * network plugin: Fix the handling of `type' in the network protocol.
1288 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1289 much larger buffer. This caused the `type' to be transferred much
1290 more often than necessary. In some cases, e. g. the `cpu' and
1291 `cpufreq' plugins being used at the same time, data may be corrupted
1292 in those files. Thanks to Bruno Prémont for debugging and reporting
1293 this issue.
1294 * processes plugin: Fix a possible segmentation fault when specifying
1295 invalid configuration options.
1296 * unixsock plugin: Make sure the initialization function is run only
1297 once. This resolves a file descriptor leak under systems which run
1298 the initialization more than once, such as Solaris.
1300 2008-10-16, Version 4.5.1
1301 * build system: Change `--enable-<plugin>' to abort with an error if
1302 dependencies are not met. Thanks to Bruno Prémont for the patch.
1303 Also, the poisoning of various string functions has been restricted
1304 to debug builds.
1305 * collectd: Fix a memory leak in the global value cache. With every
1306 *missing* value a couple of bytes would be leaked. Another memory
1307 leak in the configuration handling code has been fixed. Thanks to
1308 Niraj Tolia for reporting these issues.
1309 * collectd: Fix an off-by-one error in the ignorelist functionality.
1310 When using regular expressions, the last character would be missing,
1311 possibly matching differently from what one would expect.
1312 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1313 problem.
1314 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1315 Linzberger for reporting the bug.
1316 * iptables plugin: Fix an off-by-one error. If a string was just one
1317 character too long, it was truncated instead of reporting an error.
1318 * network plugin: Fix a memory leak in the configuration handling
1319 code. Thanks to Niraj Tolia for reporting this issue.
1320 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1321 * postgresql plugin: Don't reopen connection during reinitialization.
1322 This fixes a bug under Solaris and potentially other platforms.
1323 Missing calls to `PQclear' have been added, too. This fixes memory
1324 leaks. Thanks to ``Admin'' for reporting these bugs.
1325 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1326 library.
1327 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1328 problems with some `libc's. Thanks to Matthias Lay for reporting the
1329 bug.
1331 2008-09-04, Version 4.5.0
1332 * collectd: Added the ability to flush certain identifiers.
1333 * collectd: The concept of `notification meta data' has been
1334 introduced.
1335 * filecount plugin: The new filecount plugin counts the number of
1336 files in a directory and its subdirectories.
1337 * ipmi plugin: Sensor names have been changed to ensure unique names.
1338 Notifications upon added and removed sensors can now be generated.
1339 * notify_desktop plugin: This new plugin sends notifications to the
1340 X desktop using the structure defined in the `Desktop Notification
1341 Specification'.
1342 * notify_email plugin: This new plugin sends out notifications via
1343 email, using the `esmtp' library.
1344 * onewire plugin: The new experimental(!) onewire plugin reads values,
1345 such as temperatures, from sensors connected to the computer via the
1346 onewire bus.
1347 * perl plugin: Improved synchronized access to internal data structures
1348 and fixed a possible dead-lock.
1349 * perl plugin: Added the ability to flush certain identifiers and marked
1350 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1351 plugin_flush().
1352 * perl plugin: Added the ability to configure Perl plugins.
1353 * postgresql plugin: The new postgresql plugin collects statistics
1354 about or from a PostgreSQL database.
1355 * processes plugin: The `ProcessMatch' option has been added.
1356 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1357 IO load.
1358 * tcpconns plugin: This plugin has been ported to OpenBSD.
1359 * thermal plugin: The new thermal plugin collects system temperatures
1360 using Linux ACPI thermal zone data.
1362 2009-01-02, Version 4.4.5
1363 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1364 file may be in both locations, especially when the database was
1365 installed in a non-standard path. Thanks to Dusty Doris for
1366 reporting this.
1367 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1368 Solaris, in the configure script automatically.
1369 * collectd.conf(5): Various fixes and clarifications.
1370 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1371 portability problems, especially for Solaris.
1372 * dns plugin: Fix a portability problem with NetBSD.
1373 * network plugin: Fix the handling of `type' in the network protocol.
1374 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1375 much larger buffer. This caused the `type' to be transferred much
1376 more often than necessary. In some cases, e. g. the `cpu' and
1377 `cpufreq' plugins being used at the same time, data may be corrupted
1378 in those files. Thanks to Bruno Prémont for debugging and reporting
1379 this issue.
1380 * unixsock plugin: Make sure the initialization function is run only
1381 once. This resolves a file descriptor leak under systems which run
1382 the initialization more than once, such as Solaris.
1384 2008-10-16, Version 4.4.4
1385 * build system: Change `--enable-<plugin>' to abort with an error if
1386 dependencies are not met. Thanks to Bruno Prémont for the patch.
1387 Also, the poisoning of various string functions has been restricted
1388 to debug builds.
1389 * collectd: Fix a memory leak in the global value cache. With every
1390 *missing* value a couple of bytes would be leaked. Another memory
1391 leak in the configuration handling code has been fixed. Thanks to
1392 Niraj Tolia for reporting these issues.
1393 * collectd: Fix an off-by-one error in the ignorelist functionality.
1394 When using regular expressions, the last character would be missing,
1395 possibly matching differently from what one would expect.
1396 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1397 problem.
1398 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1399 Linzberger for reporting the bug.
1400 * network plugin: Fix a memory leak in the configuration handling
1401 code. Thanks to Niraj Tolia for reporting this issue.
1402 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1403 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1404 problems with some `libc's. Thanks to Matthias Lay for reporting the
1405 bug.
1407 2008-09-01, Version 4.4.3
1408 * collectd: Fix a memory leak in the threshold checking code.
1409 * memcached plugin: Fix a too short timeout and a related file
1410 descriptor leak.
1411 * memory plugin: A typo in the libstatgrab code has been fixed.
1412 * snmp plugin: Fix a possible memory leak.
1414 2008-07-15, Version 4.4.2
1415 * build system: Use pkg-config to detect the upsclient library.
1416 * collectd: Try even harder to determine the endianess of the
1417 architecture collectd is being built on.
1418 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1419 of disks.
1420 * dns plugin: Fix compilation errors with BIND versions 19991001
1421 through 19991005.
1422 * network plugin: Bugfix in the init routine: The init function
1423 cleared a buffer regardless of its contents. This could lead to lost
1424 values under Solaris.
1425 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1426 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1427 function.
1428 * wireless plugin: Work around incorrect noise and power values
1429 returned by some broken drivers.
1431 2008-06-03, Version 4.4.1
1432 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1433 to kyrone for reporting this.
1434 * collectd: Fixed min/max output in notifications generated by
1435 threshold checking.
1436 * collectd-nagios: Fix the protocol used to communicate with the
1437 daemon.
1438 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1439 initialization has errors. An issue with Perl 5.10 has been fixed.
1440 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1441 René Rebe and Siegmund Gorr for reporting this.
1443 2008-05-06, Version 4.4.0
1444 * collectd: Internal code cleanups.
1445 * collectd: Added support for a `Flush' command in the unixsock and
1446 exec plugins. This command can be used to force a plugin (or all) to
1447 flush its values to disk.
1448 * collectd: Thresholds can now be configured to apply to one data
1449 source only, making it possible to configure different thresholds
1450 for each data source.
1451 * apache, nginx plugins: Added the possibility to disable host and/or
1452 peer verification.
1453 * ascent plugin: The new ascent plugin reads and parses the statistics
1454 page of an Ascent server.
1455 * cpu plugin: Support for the statgrab library has been added.
1456 * disk plugin: The possibility to ignore certain disks or collect only
1457 specific disks has been added.
1458 * disk plugin: Support for the statgrab library has been added.
1459 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1460 sensor values via IPMI, the intelligent platform management
1461 interface.
1462 * iptables plugin: The iptc library that is used by the iptables
1463 plugin has been added to the distribution, because it is not
1464 provided by all distributions and removed from at least one.
1465 * powerdns plugin: The new powerdns plugin reads statistics from an
1466 authoritative or a recursing PowerDNS name server.
1467 * rrdtool plugin: The size of the files generated with the default
1468 configuration has been decreased.
1469 * tail plugin: The new tail plugin can be used to gather statistics by
1470 continuously reading from log files.
1471 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1472 TeamSpeak2 server and collects statistics about the number of users
1473 and number of channels.
1474 * users plugin: Support for the statgrab library has been added.
1475 * vmem plugin: The new vmem plugin collects very detailed statistics
1476 about the virtual memory subsystem of Linux.
1478 2008-08-30, Version 4.3.4
1479 * Build system: Improved detection of and linking with the statgrab
1480 library.
1481 * collectd: Portability fixes, especially to determine endianess more
1482 reliable.
1483 * Various plugins: Fix format strings.
1484 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1485 again has been applied.
1486 * memcached plugin: Fix a too short timeout and a related file
1487 descriptor leak.
1488 * memory plugin: A typo in the libstatgrab code has been fixed.
1489 * network plugin: A fix in the initialization function solves problems
1490 under Solaris.
1491 * nginx plugin: A thread-unsafe function has been replaced.
1492 * vserver plugin: A thread-unsafe function has been replaced.
1493 * wireless plugin: A work-around for broken wireless drivers has been
1494 added.
1496 2008-04-22, Version 4.3.3
1497 * build system: Improved detection of several libraries, especially if
1498 they are in non-standard paths.
1499 * build system: Portability fixes: Automatically define "_REENTRANT"
1500 if the libc expects it.
1501 * collectd: Error and warning messages have been improved.
1502 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1503 using them.
1504 * apache plugin: Allocate new memory when reading a webpage instead of
1505 using a buffer of static size.
1506 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1507 the program.
1508 * hddtemp plugin: Error and warning messages have been improved.
1509 * sensors plugin: Fix sensor collection for some chip types.
1511 2008-03-29, Version 4.3.2
1512 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1513 `Persist' threshold options.
1514 * collectd: Fix handling of missing values in the global value cache.
1515 * collectd: Improved error messages when parsing the configuration.
1516 * sensors plugin: Fix temperature collection with libsensors4.
1517 * unixsock plugin: Fix mixed input and output operation on streams.
1518 * wireless plugin: Fix reading noise value.
1520 2008-03-05, Version 4.3.1
1521 * exec plugin: Set supplementary group IDs.
1522 * network plugin:
1523 + Use `memcpy' when constructing/parsing a package to avoid
1524 alignment problems on weird architectures, such as Sparc.
1525 + Translate doubles to/from the x86 byte representation to ensure
1526 cross-platform compatibility.
1527 * ping plugin: Correct the handling of the `TTL' setting.
1528 * swap plugin: Reapply a patch for Solaris.
1529 * tcpconns plugin: Portability improvements.
1531 2008-02-18, Version 4.3.0
1532 * collectd: Notifications have been added to the daemon. Notifications
1533 are status messages that may be associated with a data instance.
1534 * collectd: Threshold checking has been added to the daemon. This
1535 means that you can configure threshold values for each data
1536 instance. If this threshold is exceeded a notification will be
1537 created.
1538 * collectd: The new `FQDNLookup' option tells the daemon to use the
1539 full qualified domain name as the hostname, not just the host part
1540 es returned by `gethostname(2)'.
1541 * collectd: Support for more than one `TypesDB' file has been added.
1542 This is useful when one such file is included in a package but one
1543 wants to add custom type definitions.
1544 * collectd: The `Include' config option has been expanded to handle
1545 entire directories and shell wildcards.
1546 * collectdmon: The new `collectdmon' binary detects when collectd
1547 terminates and automatically restarts it again.
1548 * csv plugin: The CSV plugin is now able to store counter values as a
1549 rate, using the `StoreRates' configuration option.
1550 * exec plugin: Handling of notifications has been added and the
1551 ability to pass arguments to the executed programs has been added.
1552 * hddtemp plugin: The new `TranslateDevicename' option lets you
1553 disable the translation from device names to major-minor-numbers.
1554 * logfile plugin: Handling of notifications has been added.
1555 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1556 domain name lookups in this plugin.
1557 * perl plugin: Many internal changes added support for handling multiple
1558 threads making the plugin reasonably usable inside collectd. The API has
1559 been extended to support notifications and export global variables to
1560 Perl plugins; callbacks now have to be identified by name rather than a
1561 pointer to a subroutine. The plugin is no longer experimental.
1562 * uuid plugin: The new UUID plugin sets the hostname to an unique
1563 identifier for this host. This is meant for setups where each client
1564 may migrate to another physical host, possibly going through one or
1565 more name changes in the process. Thanks to Richard Jones from
1566 Red Hat's Emerging Technology group for this plugin.
1567 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1568 CPU, disk and network statistics about guest systems on the same
1569 physical server. Thanks to Richard Jones from Red Hat's Emerging
1570 Technology group for this plugin.
1572 2008-04-22, Version 4.2.7
1573 * build system: Improved detection of several libraries, especially if
1574 they are in non-standard paths.
1575 * build system: Portability fixes: Automatically define "_REENTRANT"
1576 if the libc expects it.
1577 * collectd: Error and warning messages have been improved.
1578 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1579 using them.
1580 * apache plugin: Allocate new memory when reading a webpage instead of
1581 using a buffer of static size.
1582 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1583 the program.
1584 * hddtemp plugin: Error and warning messages have been improved.
1585 * sensors plugin: Fix sensor collection for some chip types.
1587 2008-03-29, Version 4.2.6
1588 * collectd: Improved error messages when parsing the configuration.
1589 * sensors plugin: Fix temperature collection with libsensors4.
1590 * unixsock plugin: Fix mixed input and output operation on streams.
1591 * wireless plugin: Fix reading noise value.
1593 2008-03-04, Version 4.2.5
1594 * apache plugin: Improved initialization and error messages.
1595 * exec plugin: Set supplementary group IDs.
1596 * network plugin:
1597 + Create separate threads for reading from the socket and parsing
1598 and dispatching incoming packets. Versions prior to this may have
1599 problems in high-load situations, where the socket receive buffers
1600 overflows, resulting in gaps in the data.
1601 + Use `memcpy' when constructing/parsing a package to avoid
1602 alignment problems on weird architectures, such as Sparc.
1603 + Translate doubles to/from the x86 byte representation to ensure
1604 cross-platform compatibility.
1605 * ping plugin: Correct the handling of the `TTL' setting.
1606 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1607 * swap plugin: Reapply a patch for Solaris.
1608 * tcpconns plugin: Portability improvements.
1610 2008-01-21, Version 4.2.4
1611 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1612 the permission on the socket as documented in the manpage. Thanks to
1613 Evgeny Chukreev for fixing this issue.
1614 * collectd: The documentation has been improved.
1616 2007-12-28, Version 4.2.3
1617 * sensors plugin: Updated the plugin to build and work with version 3
1618 of the libsensors library.
1620 2007-12-15, Version 4.2.2
1621 * nginx plugin: Incorrect comparison of strings lead to a segfault
1622 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1623 this.
1624 * logfile plugin: The config option `Timestamp' was handled
1625 incorrectly and basically always active. Thanks to Luke Heberling
1626 for fixing this.
1628 2007-11-08, Version 4.2.1
1629 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1630 enabled on the host.
1631 * snmp plugin: Fix a memory leak.
1633 2007-10-27, Version 4.2.0
1634 * collectd: The new config option `Include' lets you include other
1635 configfiles and thus split up your config into smaller parts. This
1636 may be especially interesting for the snmp plugin to keep the data
1637 definitions separate from the host definitions.
1638 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1639 (number of connections, octets and packets for each service and
1640 destination). Thanks to Sebastian Harl for this plugin.
1641 * memcached plugin: The new `memcached' plugin connects to a memcached
1642 daemon process and collects statistics of this distributed caching
1643 system. Thanks to Antony Dovgal for contributing this plugin.
1644 * nginx plugin: The new `nginx' plugin reads the status page of an
1645 nginx daemon and saves the handled connections and requests.
1646 * perl plugin: Many changes, including the added `EnableDebugger'
1647 config option which lets you debug your Perl plugins more easily.
1648 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1649 be more thread-safe otherwise by locking calls to the library.
1650 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1651 correct the values returned by SNMP-agents. If a <data> block is
1652 defined as `table' the instance is now optional. The sequence number
1653 is used as the type-instance in this case. The new `InstancePrefix'
1654 option allows to add arbitrary prefixes to the type-instance.
1655 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1656 certain TCP connections and what state they're in. This can be used
1657 to see how many connections your FTP server has to handle or how
1658 many outgoing connections your mailserver has open.
1660 2008-01-11, Version 4.1.6
1661 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1662 the permission on the socket as documented in the manpage. Thanks to
1663 Evgeny Chukreev for fixing this issue.
1664 * collectd: The documentation has been improved.
1666 2007-12-27, Version 4.1.5
1667 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1668 memory situations.
1669 * sensors plugin: Updated the plugin to build and work with version 3
1670 of the libsensors library.
1672 2007-11-08, Version 4.1.4
1673 * Build system: Improve detection of the rrd library, especially if
1674 it's in a non-standard location.
1675 * Build system: A bug when parsing the argument for
1676 `--with-libnetsnmp' has been fixed.
1677 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1678 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1679 a deadlock or delay when shutting down the daemon.
1680 * snmp plugin: Fix a memory leak.
1682 2007-10-24, Version 4.1.3
1683 * collectd: A build issue under Solaris has been resolved by renaming
1684 data types.
1685 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1686 be more thread-safe otherwise by locking calls to the library.
1688 2007-09-28, Version 4.1.2
1689 * apcups plugin: Fix reporting of the `load percent' data.
1690 * wireless plugin: Correct the handling of cards returning signal and
1691 noise quality as percentage.
1692 * perl plugin: Fix a possible buffer overflow in get_module_name().
1693 * build system: Further improve the detection of libraries.
1694 * netlink plugin: Build issues under some older versions of the Linux
1695 includes (i. e. Debian Sarge) have been fixed.
1696 * snmp plugin: Fix a potential segfault when a host times out. Add
1697 support for the `timeticks' type.
1699 2007-09-12, Version 4.1.1
1700 * Build system: The detection of `libnetlink' has been improved.
1701 * collectd: The documentation has been fixed in numerous places.
1702 * exec plugin: Setting the group under which to run a program has been
1703 fixed.
1704 * collectd: The `sstrerror' function was improved to work correctly
1705 with the broken GNU version of `strerror_r'.
1706 * collectd: Write an error message to STDERR when loading of a plugin
1707 fails.
1708 * apcups plugin: Fix the `types' used to submit the values: They still
1709 has an `apcups_' prefix which doesn't work anymore.
1710 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1711 whatever the client thinks is `now'..
1713 2007-09-01, Version 4.1.0
1714 * Build system: The build system has been changed to automatically
1715 disable all plugins, which are missing dependencies. The dependency
1716 checking has been removed from the plugins themselves to remove
1717 redundancy.
1718 * Flexible interval: The interval of collected data is now sent along
1719 with the data itself over the network, so that the interval-settings
1720 of server and clients no longer needs to match.
1721 * netlink plugin: The new `netlink' plugin connects to the Linux
1722 kernel using a netlink socket and uses it to query information about
1723 interfaces, qdiscs and classes.
1724 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1725 to not block data collection.
1726 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1727 network devices, such as switches, routers, thermometers, rack
1728 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1729 plugin.
1730 * unixsock plugin: Added the `LISTVAL' command.
1731 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1732 of music played with xmms.
1734 2007-09-28, Version 4.0.9
1735 * apcups plugin: Fix reporting of the `load percent' data.
1736 * wireless plugin: Correct the handling of cards returning signal and
1737 noise quality as percentage.
1738 * perl plugin: Fix a possible buffer overflow in get_module_name().
1740 2007-09-12, Version 4.0.8
1741 * collectd: The `sstrerror' function was improved to work correctly
1742 with the broken GNU version of `strerror_r'.
1743 * collectd: Write an error message to STDERR when loading of a plugin
1744 fails.
1745 * apcups plugin: Fix the `types' used to submit the values: They still
1746 has an `apcups_' prefix which doesn't work anymore.
1747 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1748 whatever the client thinks is `now'..
1750 2007-08-26, Version 4.0.7
1751 * documentation: Some typos have been fixed and some information has
1752 been improved.
1753 * build system: Many fixes for detecting libraries in unusual places,
1754 such as on RedHat systems. The affected libraries are `libcurl',
1755 `libmysql', and `libupsclient'.
1756 * network plugin: Allow the `Port' option to be specified as a number
1757 (i. e. without quotes).
1758 * nut plugin: A fix allows linking the nut plugin against
1759 libupsclient, version >= 2.2.0.
1760 * processes plugin: Fix a potential segmentation fault.
1762 2007-07-30, Version 4.0.6
1763 * sensors plugin: Fix the ignorelist functionality: Only the `type
1764 instance' was used to match against the list, but the documentation
1765 told otherwise. This release fixes the code, so it complies with the
1766 documentation.
1767 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1768 configuration messages will end up in the logging facility.
1769 * conrtib/fedora: The contributed specfile for Fedora has been
1770 updated.
1772 2007-07-05, Version 4.0.5
1773 * Portability: More fixes for OpenBSD have been included.
1775 2007-06-24, Version 4.0.4
1776 * cpu plugin: Fixed the Solaris code.
1777 * dns plugin: Fixed a build issue for OpenBSD.
1778 * interface plugin: Fixed the Solaris code.
1779 * load plugin: Fixed the alternative `/proc' Linux code.
1780 * memory plugin: Fixed the Solaris code.
1781 * oconfig: Don't require `-lfl' anymore.
1783 2007-06-19, Version 4.0.3
1784 * cpu plugin: Fix the Darwin / Mac OS X code.
1785 * ping plugin: Use the return value of `getpid', not its address.
1786 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1787 initialized correctly.
1788 * configure: Added `--with-nan-emulation' to aid cross compilation.
1790 2007-06-12, Version 4.0.2
1791 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1792 they're given in numerically form.
1794 2007-06-07, Version 4.0.1
1795 * iptables plugin: A bug in the configuration routine has been fixed.
1796 Setting a comment in the configfile will no longer cause a
1797 segmentation fault.
1799 2007-06-03, Version 4.0.0
1800 * collectd: The plugin-infrastructure has been changed to allow for
1801 more types of plugins, namely `write' and `log' plugins.
1802 * collectd: The read-function has been changed to read many plugins in
1803 parallel, using threads. Thus, plugins generally need to use
1804 thread-safe functions from now on.
1805 * collectd: The '-t' command line options allows to perform syntax tests
1806 of the configuration file and exit immediately.
1807 * csv plugin: The new `csv' plugin handles output to `comma separated
1808 values'-files.
1809 * rrdtool plugin: The new `rrdtool' plugin handles output to
1810 RRD-files. Data can be cached to combine multiple updates into one
1811 write to increase IO-performance.
1812 * network plugin: The new `network' plugin handles IO via the network.
1813 It implements a different, much more extensible protocol which can
1814 combine many values in one packet, decreasing the number of UDP-
1815 packets being sent. It can read from and send to the network and
1816 with the appropriate configuration even forward packets to other
1817 networks.
1818 * unixsock plugin: The new `unixsock' plugin provides an interface to
1819 communicate with the daemon while it is running. Right now the
1820 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1821 come.
1822 * perl plugin: The new `perl' plugin allows you to write extensions
1823 for collectd in the scripting-language Perl.
1824 * logfile plugin: The new `logfile' plugin writes logmessages to files
1825 or STDOUT or STDERR.
1826 * syslog plugin: The new `syslog' plugin sends logmessages to the
1827 system's syslog daemon.
1828 * entropy plugin: The new `entropy' plugin collects the amount of
1829 entropy currently being available to the system.
1830 * exec plugin: The new `exec' plugin forks child processes and reads
1831 back values provided by the forked processes.
1832 * iptables plugin: The new `iptables' plugin reads counters from
1833 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1834 plugin.
1835 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1836 to Peter Holik for contributing this plugin.
1837 * nut plugin: The new `nut' plugin connects the upsd of the `network
1838 ups tools' and reads information about the connected UPS.
1839 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1840 connections) field was added by Florent Monbillard.
1841 * collectd-nagios: The new `collectd-nagios' binary queries values
1842 from collectd, parses them and exits according to Nagios-standards.
1843 * manpages: The manpages have been improved a lot.
1845 2007-09-28, Version 3.11.7
1846 * wireless plugin: Correct the handling of cards returning signal and
1847 noise quality as percentage.
1849 2007-08-31, Version 3.11.6
1850 * processes plugin: Fix a potential segmentation fault.
1852 2007-05-29, Version 3.11.5
1853 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1854 * ntpd plugin: Fix a potential buffer overflow.
1855 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1856 were accounted as `zombies'.
1858 2007-04-10, Version 3.11.4
1859 * dns plugin: Change the order of includes to make the plugin compile
1860 under FreeBSD.
1862 2007-03-30, Version 3.11.3
1863 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1864 of the unused `COLLECT_KSTAT'.
1866 2007-02-11, Version 3.11.2
1867 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1868 NULL-pointer may have been passed to `printf' which causes a
1869 segfault with some libcs.
1871 2007-02-10, Version 3.11.1
1872 * df plugin: Some wrong defines have been fixed so the plugin works
1873 under Solaris again.
1874 * dns plugin: The usage of a struct has been fixed to work with
1875 non-GNU libcs.
1876 * processes plugin: Some missing defines have been added so the plugin
1877 compiles cleanly under FreeBSD and presumably other UNIXes.
1879 2006-12-22, Version 3.11.0
1880 * collectd: The new command line option `-P' makes it easier for
1881 distributors to change the location of PID-files.
1882 * collectd: The daemon shuts down faster now which makes it easier to
1883 write init.d-scripts for it.
1884 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1885 caused problems every now and then.
1886 * df plugin: New config options allow to ignore certain mountpoints,
1887 filesystem types or devices.
1888 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1889 and interprets it. It collects traffic as well as qtype, opcode and
1890 rcode counts.
1891 * email plugin: Sebastian Harl has contributed this plugin which
1892 counts received mails in categories (e. g. ham, spam, virus), spam
1893 score (as given by SpamAssassin) and check types.
1894 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1895 uses `mbmon' to gather information from sensors on the motherboard.
1896 * processes plugin: Collect detailed statistics for configured
1897 processes, that's process and thread count, CPU usage, resident
1898 segment size and pagefaults.
1899 * multimeter plugin: Peter Holik contributed a new plugin which
1900 queries multimeters.
1901 * sensors plugin: Lubos Stanek has put much effort into improving this
1902 plugin, including `extended naming', collection of voltage values
1903 and the possibility to ignore certain values.
1905 2006-12-21, Version 3.10.4
1906 * Max Kellermann has identified a bug in the server routine: When
1907 opening a socket fails the daemon will (re)try opening the socket in
1908 an endless loop, ultimately leading to a `EMFILE' error.
1910 2006-11-04, Version 3.10.3
1911 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1912 ntpd's reply was sent in more than one packet, the buffer size was
1913 calculated incorrectly, resulting in the reading of uninitialized or
1914 freed memory.
1916 2006-11-01, Version 3.10.2
1917 * The sample config file has been improved.
1918 * Errors in the manpages have been corrected.
1919 * The ping-plugin now adds hosts during initialization, not during
1920 startup. This speeds up startup when no network connectivity is
1921 available. Also, the hosts are being added later when the network is
1922 available.
1923 * Improved BSD-support for the df-plugin.
1924 * Fixed syntax errors in the swap-plugin for Mac OS X.
1925 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1926 plugin.
1927 * Don't disable the mysql-plugin if connecting to the database fails
1928 during initialization. Instead, try again in increasing intervals.
1930 2006-07-19, Version 3.10.1
1931 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1932 the apcups cannot be reached, unconnected sockets will pile up and
1933 eventually lead to `Too many open files' errors.
1935 2006-07-09, Version 3.10.0
1936 * The `disk' plugin has been ported to Darwin.
1937 * The `battery' plugin should work on many Apple computers now.
1938 * The `traffic' plugin can now ignore certain interfaces. Also,
1939 statistics for sent/received packets and errors have been added.
1940 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1941 to Anthony Gialluca for contributing this plugin and providing me
1942 with a test environment :)
1943 * A plugin for monitoring an NTP instance and the local clock drift
1944 has been added.
1946 2006-06-25, Version 3.9.4
1947 * The Solaris code in the `swap' plugin has been changed to reflect
1948 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1949 working this out.
1950 * The debugging system has been fixed to work with the Sun libc.
1951 * When built without librrd the variable `operating_mode' could be
1952 uninitialized. Thanks to David Elliot for reporting the bug.
1954 2006-06-01, Version 3.9.3
1955 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1956 operating systems also profit from the changes, but I wasn't able to
1957 check that.
1958 * Changed the build system to find the netinet-includes under FreeBSD
1959 and therefore successfully build the `liboping' library there.
1961 2006-05-09, Version 3.9.2
1962 * Applied a patch to the `liboping' library. Due to a bug in the
1963 sequence checking the `ping' plugin stopped working after
1964 approximately 7.6 days.
1966 2006-05-09, Version 3.8.5
1967 * Applied a patch to the `liboping' library. Due to a bug in the
1968 sequence checking the `ping' plugin stopped working after
1969 approximately 7.6 days.
1971 2006-04-21, Version 3.9.1
1972 * Build issues with Solaris and possible other architectures have been
1973 resolved.
1974 * Problems when building the `apache'-plugin without `libcurl' have
1975 been resolved.
1976 * A bug in the `ping' plugin has been fixed. Sorry folks.
1978 2006-04-02, Version 3.9.0
1979 * A plugin to monitor the Apache webserver has been added.
1980 <http://httpd.apache.org/>
1981 * A plugin to collect statistics about virtual servers using VServer.
1982 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1983 this plugin :)
1984 * A plugin for wireless LAN cards has been added. It monitors signal
1985 strength, link quality and noise ratio..
1986 * A plugin for Apple hardware sensors has been added.
1987 * An option to compile collectd with different `step' and `heartbeat'
1988 settings has been added. The size of RRAs is no longer static but
1989 calculated based on the settings for `step' and `width'.
1990 * The `ping' plugin can now be configured to use a certain TTL.
1991 * A plugin to monitor the hardware sensors of Apple computers has been
1992 added.
1993 * The plugins `cpu', `memory', `processes' and `traffic' have been
1994 ported to Mach/Darwin (Mac OS X).
1995 * The `log mode' has been contributed by Christophe Kalt. It writes
1996 the data into text files rather than RRD files.
1998 2006-04-09, Version 3.8.4
1999 * Applied patch by Vincent Stehlé which improves the disk-name
2000 resolution in the `hddtemp' plugin for Linux systems.
2002 2006-04-02, Version 3.8.3
2003 * Applied a patch by James Byers: The MySQL plugin was not working
2004 with MySQL 5.0.2 or later.
2006 2006-03-14, Version 3.8.2
2007 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2008 the GNU libc, because it points to `/etc/fstab' rather than
2009 `/etc/mtab'.
2011 2006-03-13, Version 3.8.1
2012 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2013 * Fixes in the debian `postinst' and `init.d' scripts.
2015 2006-03-09, Version 3.8.0
2016 * The `ping' plugin no longer uses `libping' but a self written
2017 library named `liboping'. With this library it's possible to ping
2018 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2020 2006-02-18, Version 3.7.2
2021 * A simple bug in the `battery' plugin has been fixed. It should now
2022 work with ACPI based batteries as well. Thanks to Sebastian for
2023 fixing this.
2024 * Fixing a bug that prevented collectd to be built without librrd.
2025 Thanks to Werner Heuser for reporting it.
2027 2006-02-04, Version 3.7.1
2028 * The new network code has been improved to build with older versions
2029 of glibc.
2030 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2031 to Tommie Gannert for this patch.
2033 2006-01-30, Version 3.7.0
2034 * The `battery' plugin has been added. It collects information about
2035 laptop batteries..
2036 * The MySQL plugin has been improved: It now writes two more RRD
2037 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2038 * The `cpufreq' plugin now reads another file since the file it did
2039 read so far causes much overhead in the kernel. Also, you need root
2040 to read the old file, but not to read the new one.
2041 * The `hddtemp' plugin can now be configured to connect to another
2042 address and/or port than localhost.
2043 * The `df' plugin now prefers `statvfs' over `statfs'.
2044 * The network code has been rewritten. collectd now supports unicast
2045 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2046 be set in the configfile.
2048 2006-01-24, Version 3.6.2
2049 * Due to a bug in the configfile handling collectd wouldn't start in
2050 client mode. This released fixes this.
2052 2006-01-20, Version 3.6.1
2053 * Due to a bug in `configure.in' all modules and the binary were
2054 linked against `libmysqlclient'. This issue is solved by this
2055 release.
2057 2006-01-17, Version 3.6.0
2058 * A config file has been added. This allows for loading only specific
2059 plugins.
2060 * A `df' plugin has been added.
2061 * A `mysql' plugin has been added.
2062 * The `ping' plugin doesn't entirely give up hope when a socket error
2063 occurred, but will back of and increase the intervals between tries.
2065 2006-01-21, Version 3.5.2
2066 * Fixed yet another bug in the signal handling.. Stupid typo..
2067 * Improved the ping plugin to not give up on socket errors (backport
2068 from 3.6.0).
2070 2005-12-18, Version 3.5.1
2071 * The PID-file is now deleted correctly when shutting down the daemon.
2072 * SIGINT and SIGTERM are now handled correctly.
2074 2005-12-16, Version 3.5.0 (Revision 326)
2075 * A bug in the `load' module under Solaris has been fixed.
2076 * The `users' module has been contributed by Sebastian Harl. It counts
2077 currently logged in users.
2078 * The CPU module now works under FreeBSD without the use of
2079 `libstatgrab', however SMP support is missing.
2080 * The default directories for the RRD files and the PID file now
2081 depend on the compile time setting of `localstatedir'.
2083 2005-11-15, Version 3.4.0 (Revision 236)
2084 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2085 from gentoo's bugzilla for writing the patch.
2086 * The build dependency for librrd has been removed. Binaries built
2087 without librrd are client-only and will multicast their value as
2088 with the `-c' argument.
2089 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2090 * The newly introduced `-f' switch prevents daemon initialization
2091 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2092 Barcellos for this patch.
2094 2005-11-04, Version 3.3.0 (Revision 216)
2095 * New modules have been added:
2096 - `serial', for monitoring traffic on the serial interfaces
2097 - `nfs', for graphing NFS procedure calls
2098 - `tape', traffic from/to tape devices
2099 * The memory.rrd now accepts more than 4Gig of memory.
2101 2005-10-26, Version 3.2.0 (Revision 200)
2102 * Support for graphing the processes has been added (thanks to Lyonel
2103 Vincent)
2104 * If reading from hddtemp fails collectd will increase the time
2105 between polls up to one day.
2106 * The init.d files have been improved.
2107 * Problems with the spec file have been fixed.
2109 2005-10-16, Version 3.1.0 (Revision 194)
2110 * Added the `setsid' syscall to the startup code.
2111 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2113 2005-09-30, Version 3.0.0 (Revision 184)
2114 * The ability to send/receive data to/from the network (think
2115 multicast) has been added.
2116 * Modules have been split up into shared libraries can be loaded at
2117 runtime. The biggest advantage is that the core program doesn't need
2118 to be linked against an external library.
2119 * A patch by George Kargiotakis has been applied: It fixes the sensors
2120 behaviour then more than one sensor is being queried.
2122 2005-09-16, Version 2.1.0 (Revision 172)
2123 * A module for swap statistics has been added.
2125 2005-09-09, Version 2.0.0 (Revision 135)
2126 * Filenames can no longer be configured at program startup. The only
2127 options as of this version are the directory and ping hosts.
2128 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2129 Soft-IRQ statistics are added to `System'.
2130 * Diskstats now collect read and write bytes, not sectors.
2131 * Ping statistics can now be collected for more than one host. There
2132 is no default any more: If no host is given no host will be pinged.
2133 * A self-written patch for libping has been applied so it builds
2134 cleanly.
2136 2005-09-01, Version 1.8.1 (Revision 123)
2137 * Much improved configure-script: libraries and features may now be
2138 disabled.
2139 * More detailed warnings/error messages when RRD update fails.
2141 2005-08-29, Version 1.8.0:
2142 * Support for collecting disk statistics under Solaris.
2144 2005-08-25, Version 1.7.0:
2145 * Support for libstatgrab[1] for load, memory usage and network
2146 traffic. CPU- and disk-usage are not (yet) supported, since
2147 libstatgrab returns insufficient information. I will contact the
2148 authors.
2149 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2150 aren't necessarily counted linear which is now handled correctly.
2151 [1]: http://www.i-scream.org/libstatgrab/
2153 2005-08-21, Version 1.6.0:
2154 * Basic support for Solaris: System load and cpu-usage can be
2155 collected under Solaris, too. Other stats will follow later.
2156 * Many fixes in the autoconf-script
2157 * Collection/Museum scripts have been added under contrib/museum
2158 * collectd may now be started in unprivileged mode, though ping
2159 statistics will not work.
2161 2005-07-17, Version 1.5.1:
2162 * Diskstats-RRDs now use major/minor for naming. Some systems have
2163 weird strings as disk-names..
2165 2005-07-17, Version 1.5:
2166 * A new module, diskstats, has been added. It collects information
2167 about the disks and partitions.
2169 2005-07-11, Version 1.4.2:
2170 * The meminfo module has been changed to work with more platforms
2171 and/or kernel versions.
2173 2005-07-10, Version 1.4.1: Correct traffic stats
2174 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2175 forgot to correct when I changed that module.
2177 2005-07-09, Version 1.4: More traffic stats
2178 * Traffic is now collected for all interfaces that can be found
2179 * Temperature-statistics are read from lm-sensors if available
2181 2005-07-08, Version 1.3: CPU stats
2182 * Collecting CPU statistics now
2184 2005-07-12, Version 1.2: Using syslog
2185 * collectd is now using the syslog facility to report errors, warnings
2186 and the like..
2187 * The default directory is now /var/db/collectd
2189 2005-07-10, Version 1.1: Minor changes
2190 * Nothing really useful to say ;)
2192 2005-07-09, Version 1.0: Initial Version
2193 * The following modules are provided:
2194 * Load average
2195 * Ping time
2196 * Traffic
2197 * Memory info
