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

965 fixed. Thanks to Ben Knight for his patch.
967 2009-10-03, Version 4.7.4
968 * Build system: Issues when building the iptables plugin have been
969 fixed.
970 * exec plugin: Clear the signal block mask before calling exec(2).
971 * perl plugin: Declare the “environ” variable. This solves build
972 issues on some platforms.
973 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
974 Andrés J. Díaz for the patch.
975 * unixsock plugin: Fix a (well hidden) race condition related to file
976 descriptor handling.
978 2009-09-13, Version 4.7.3
979 * collectd: Fix a possible but very rare invalid “free” in the caching
980 code. Thanks to Sebastian Harl for the patch.
981 * collectd: Remove old values when a cache entry is marked as missing.
982 This way the “GETVAL” command of the UnixSock plugin doesn't return
983 old, no longer valid values when this happens. Thanks to Andrés J.
984 Díaz for the patch.
985 * collectd: The “plugin_unregister_read” function has been fixed.
986 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
987 to follow redirects. Thanks to Joey Hess for reporting this bug.
988 * df plugin: Check the ignorelist before stating the file system,
989 possibly reducing the number of stats considerably. Thanks to Joey
990 Hess for reporting this bug.
991 * iptables plugin: Support for the new libiptc API has been added.
992 Thanks to Sebastian Harl for the patch. The build system has been
993 updated to the plugin only includes the shipped header files when it
994 is linked with the shipped library, too.
995 * java plugin: Delay creating the JVM until after the daemon has
996 forked. The JVM internally creates threads that are lost when
997 forking. This means that Java-based plugins are now configured
998 during the init-phase, i. e. later than other plugins.
999 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
1000 to Alan Pevec for the patch.
1001 * network plugin: Fix the handling of the “CacheFlush” option: The
1002 value was assigned to a wrong variable. The initialization of the
1003 gcrypt library, which is used for signing / encrypting traffic, has
1004 been fixed. Thanks to Luke Heberling for the patch.
1005 * powerdns plugin: Set a timeout when reading data from the datagram
1006 socket. Handling of the “LocalSocket” option has been fixed. An
1007 incorrectly used “type” has been corrected. Thanks to Luke Heberling
1008 for his patches.

1023 details have been added to the configuration summary. Support for
1024 libtool 2.2 has been added.
1025 * collectd: Two bugs with the threshold checking have been fixed. The
1026 first one prevented thresholds to be checked at all, the second one
1027 caused wrong behavior with the persistency option. Thanks to Andrés
1028 J. Díaz for fixing these problems.
1029 * collectd: Handling of the `Include' configuration option has been
1030 fixed.
1031 * rrdtool plugin: Make sure initialization is run only once. This
1032 resolves problems under Solaris and potentially other systems.
1033 Thanks to Amit Gupta for reporting this bug.
1034 * java plugin: Make it possible to use dots ('.') instead of slashes
1035 ('/') as the class separator. Thanks to Randy Rizun for pointing
1036 this out.
1037 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1038 to Doug MacEachern for the patch.

1051 multicast traffic from Ganglia's gmond daemon.
1052 * java plugin: The new java plugin exports the collectd API to Java,
1053 making it possible to write extensions to collectd in Java.
1054 * memcachec plugin: The new memcachec plugin queries data from a
1055 memcached daemon and parses it similar to the cURL plugin. Thanks to
1056 Doug MacEachern for the initial code.
1057 * memcached plugin: Support for connections over UNIX domain sockets
1058 has been added. Thanks to Franck Lombardi for the patch.
1059 * memory plugin: Support for OpenBSD and possibly other *BSDs has been
1060 added. Thanks to Simon Kuhnle for the patch.
1061 * mysql plugin: Support to query multiple databases has been added.
1062 Thanks to Doug MacEachern for the patch.
1063 * mysql plugin: Master/slave statistics have been added.
1064 * mysql plugin: Lock statistics have been added. Thanks to Rodolphe
1065 Quiédeville for the patch.
1066 * network plugin: The possibility to sign or encrypt network traffic
1067 has been added.
1068 * protocols plugin: The new protocols plugin provides information
1069 about network protocols, such as IP, TCP and UDP.
1070 * snmp plugin: The intervals given in the configuration of the SNMP
1071 plugin must no longer be a multiple of the global interval.
1072 * table plugin: The new Table plugin provides parsing for table-like
1073 structured files, such as many files beneath /proc.
1074 * ted plugin: The new TED plugin reads power consumption measurements
1075 from “The Energy Detective” (TED). Thanks to Eric Reed for this
1076 plugin.
1077 * onewire plugin: The new `Interval' option allows collecting
1078 information from OneWire sensors at arbitrary intervals.
1079 * ping plugin: Support for collecting the drop rate and standard
1080 deviation of round-trip times has been added.
1081 * uptime plugin: The new uptime plugin can collect the server's
1082 uptime. Thanks to Marco Chiappero for the patch.
1084 2009-09-10, Version 4.6.5
1085 * collectd: Remove old values when a cache entry is marked as missing.
1086 This way the “GETVAL” command of the UnixSock plugin doesn't return
1087 old, no longer valid values when this happens. Thanks to Andrés J.
1088 Díaz for the patch.
1089 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1090 to follow redirects. Thanks to Joey Hess for reporting this bug.
1091 * df plugin: Check the ignorelist before stating the file system,
1092 possibly reducing the number of stats considerably. Thanks to Joey
1093 Hess for reporting this bug.
1094 * iptables plugin: Support for the new libiptc API has been added.
1095 Thanks to Sebastian Harl for the patch. The build system has been

1111 for reporting the bug.
1113 2009-06-02, Version 4.6.3
1114 * Build system, various plugins: Many build fixes for FreeBSD,
1115 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1116 for many fixes and providing a build system for many platforms,
1117 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1118 providing an OpenBSD system.
1119 * collectd: Two bugs with the threshold checking have been fixed. The
1120 first one prevented thresholds to be checked at all, the second one
1121 caused wrong behavior with the persistency option. Thanks to Andrés
1122 J. Díaz for fixing these problems.
1123 * collectd: Handling of the `Include' configuration option has been
1124 fixed.
1125 * battery plugin: Don't complain about a missing directory every
1126 interval.
1127 * exec plugin: Allow executed programs to close STDERR. Thanks to
1128 Thorsten von Eicken for reporting this problem.
1129 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1130 Tomasz Pala for the patch.
1131 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1132 the patch.
1133 * memory plugin: Fix a potential problem under Solaris.
1134 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1135 to Doug MacEachern for the patch.
1137 2009-03-18, Version 4.6.2
1138 * collectd: Some Solaris utility code has been improved.
1139 * filter subsystem: Allow `Chains' without default targets.
1140 * liboping: A patch to comply with strict aliasing rules has been
1141 added.
1142 * timediff match: Fix a typo: The match was registered with a wrong
1143 name which prevented this match to be used as documented. Thanks to
1144 Bruno Prémont for finding this problem.
1145 * bind plugin: Fix collection of the cached RR sets. The number of RR
1146 sets currently in the cache was collected as a counter value, which
1147 is nonsense. Thanks to Bruno Prémont for implementing this.
1148 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1149 primarily BSDs, don't take it well and crash.
1150 * oracle plugin: Portability to 64 bit systems has been improved.
1151 * postgresql plugin: The default configuration has been improved.
1152 * rrdtool plugin: Fix a possible race condition: If the network plugin
1153 is brought and dispatches a value before the rrdtool plugin is
1154 initialized, the daemon may crash.
1156 2009-02-22, Version 4.6.1
1157 * collectd: Many documentation fixes.
1158 * Collectd::Unixsock: Error handling has been improved.
1159 * regex match: Don't link with the PCRE library.
1160 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1161 for finding and fixing most of them.
1162 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1163 faults. Thanks to Peter Holik for his patch.
1165 2009-02-16, Version 4.6.0
1166 * collectd: Added the `filter chain' infrastructure, which allows the
1167 user to use `matches' and `targets' to control value processing.
1168 * collectd: The new `-T' command line argument allows more in-depth
1169 testing of a configuration. Thanks to Doug MacEachern for the patch.
1170 * collectd-nagios: The Nagios integration command has been updated to
1171 use libcollectdclient. The `percentage' aggregation function has
1172 been added. Thanks to Fabian Linzberger for the patch.
1173 * libcollectdclient: A library which abstracts communication with the
1174 unixsock plugin for clients has been added.
1175 * regex match: Match values by their identifies using regular
1176 expressions.
1177 * timediff match: Match for values with an invalid timestamp.
1178 * value match: Select values by their data sources' values.
1179 * notification target: Create and dispatch a notification.
1180 * replace target: Replace parts of an identifier using regular
1181 expressions.
1182 * set target: Set (overwrite) entire parts of an identifier.
1183 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1184 statistics, allowing very detailed name server statistics. Thanks to
1185 Bruno Prémont for this plugin.
1186 * cpu plugin: Report `interrupt' separately when using
1187 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1188 example for native OpenBSD support, has been added. Thanks to Simon
1189 Kuhnle for the patch.
1190 * csv plugin: Make it possible to write values to STDOUT instead of
1191 files. This is meant for testing purposes mostly. The output written
1192 to STDOUT is compatible with the exec plugin. Thanks to Doug
1193 MacEachern for the patch.
1194 * curl plugin: This new plugin can be used to read web pages and parse
1195 them using the same mechanism that's used in the tail plugin.
1196 * dbi plugin: This new plugin allows you to connect to a variety of
1197 relational databases and use SQL to gather custom statistics from
1198 it. It is similar to the already existing PostgreSQL plugin but uses
1199 libdbi to communicate with the database(s).
1200 * interface plugin: Use the ignorelist framework when selecting /
1201 ignoring interfaces. This allows one to use regular expressions to
1202 select interfaces, too.
1203 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1204 Thanks to Bruno Prémont for this patch.
1205 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1206 for the patch.

1208 socket, too. Thanks to Mirko Buffoni for the patch.
1209 * network plugin: Further performance improvements for the receive
1210 code. This hopefully will help very large setups.
1211 * openvpn plugin: This new plugin collects statistics provided by the
1212 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1213 * oracle plugin: This new plugin allows you to connect to an Oracle
1214 database and use SQL to gather custom statistics from it. It is
1215 similar to the already existing PostgreSQL plugin.
1216 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1217 have been added.
1218 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1219 * perl plugin: Added support for `notification meta data'.
1220 * perl plugin: Added support for the `filter chain' infrastructure by
1221 allowing plugins to register `matches' and `targets'.
1222 * postgresql plugin: The preferred configuration syntax has been
1223 updated to be in line with the syntax used by the new dbi and oracle
1224 plugins. The compatibility code for the old syntax is present.
1225 Support for the new `Result' blocks and the interval parameter has
1226 been added.
1227 * processes plugin: Stacksize and virtual memory usage statistics have
1228 been added. Portability fixes.
1229 * rrdcached plugin: This new plugin uses the (still in development)
1230 RRD accelerator daemon, rrdcached. This daemon works very similar to
1231 the original rrdtool plugin of collectd, but adds some more nice
1232 features.
1233 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1234 added.
1236 2009-05-09, Version 4.5.4
1237 * Build system, various plugins: Many build fixes for FreeBSD,
1238 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1239 for many fixes and providing a build system for many platforms,
1240 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1241 providing an OpenBSD system.
1242 * collectd: Fix a potential race condition when creating directories.
1243 * battery plugin: Don't complain about a missing directory every
1244 interval.
1245 * dns plugin: Slight portability fixes.
1246 * exec plugin: Allow executed programs to close STDERR. Thanks to
1247 Thorsten von Eicken for reporting this problem.
1248 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1249 Tomasz Pala for the patch.
1250 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1251 the patch.
1252 * rrdtool plugin: Fix a possible race condition: If the network plugin
1253 is initialized and dispatches a value before the rrdtool plugin is
1254 initialized, the daemon may crash.
1255 * memory plugin: Fix a potential problem under Solaris.
1257 2009-02-22, Version 4.5.3
1258 * build system: The check for libupsclient even when `pkg-config' is
1259 not available.
1260 * collectd: Fix error handling in the global cache.
1261 * Collectd::Unixsock: Error handling has been improved.
1262 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1263 patch.
1264 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1265 faults. Thanks to Peter Holik for his patch.
1266 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1267 code. Thanks to "thated" for reporting this.
1269 2009-01-02, Version 4.5.2
1270 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1271 file may be in both locations, especially when the database was
1272 installed in a non-standard path. Thanks to Dusty Doris for
1273 reporting this.
1274 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1275 Solaris, in the configure script automatically.
1276 * build system, tcpconns plugin: Check for `kvm_nlist' and
1277 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1278 library with similar functions to the BSD variant, but doesn't
1279 provide these necessary functions.
1280 * collectd.conf(5): Various fixes and clarifications.
1281 * collectd: Remove a GNUism (unnamed unions), thus improving
1282 portability.
1283 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1284 This solves portability problems, especially for Solaris.
1285 * dns plugin: Fix a portability problem with NetBSD.
1286 * filecount plugin: Fix an off-by-one error. This error may cause a
1287 segmentation fault.
1288 * network plugin: Fix the handling of `type' in the network protocol.
1289 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1290 much larger buffer. This caused the `type' to be transferred much
1291 more often than necessary. In some cases, e. g. the `cpu' and
1292 `cpufreq' plugins being used at the same time, data may be corrupted
1293 in those files. Thanks to Bruno Prémont for debugging and reporting
1294 this issue.
1295 * processes plugin: Fix a possible segmentation fault when specifying
1296 invalid configuration options.
1297 * unixsock plugin: Make sure the initialization function is run only
1298 once. This resolves a file descriptor leak under systems which run
1299 the initialization more than once, such as Solaris.
1301 2008-10-16, Version 4.5.1
1302 * build system: Change `--enable-<plugin>' to abort with an error if
1303 dependencies are not met. Thanks to Bruno Prémont for the patch.
1304 Also, the poisoning of various string functions has been restricted
1305 to debug builds.
1306 * collectd: Fix a memory leak in the global value cache. With every
1307 *missing* value a couple of bytes would be leaked. Another memory
1308 leak in the configuration handling code has been fixed. Thanks to
1309 Niraj Tolia for reporting these issues.
1310 * collectd: Fix an off-by-one error in the ignorelist functionality.
1311 When using regular expressions, the last character would be missing,
1312 possibly matching differently from what one would expect.
1313 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1314 problem.
1315 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1316 Linzberger for reporting the bug.
1317 * iptables plugin: Fix an off-by-one error. If a string was just one
1318 character too long, it was truncated instead of reporting an error.
1319 * network plugin: Fix a memory leak in the configuration handling
1320 code. Thanks to Niraj Tolia for reporting this issue.
1321 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1322 * postgresql plugin: Don't reopen connection during reinitialization.
1323 This fixes a bug under Solaris and potentially other platforms.
1324 Missing calls to `PQclear' have been added, too. This fixes memory
1325 leaks. Thanks to ``Admin'' for reporting these bugs.
1326 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1327 library.
1328 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1329 problems with some `libc's. Thanks to Matthias Lay for reporting the
1330 bug.
1332 2008-09-04, Version 4.5.0
1333 * collectd: Added the ability to flush certain identifiers.
1334 * collectd: The concept of `notification meta data' has been
1335 introduced.
1336 * filecount plugin: The new filecount plugin counts the number of
1337 files in a directory and its subdirectories.
1338 * ipmi plugin: Sensor names have been changed to ensure unique names.
1339 Notifications upon added and removed sensors can now be generated.
1340 * notify_desktop plugin: This new plugin sends notifications to the
1341 X desktop using the structure defined in the `Desktop Notification
1342 Specification'.
1343 * notify_email plugin: This new plugin sends out notifications via
1344 email, using the `esmtp' library.
1345 * onewire plugin: The new experimental(!) onewire plugin reads values,
1346 such as temperatures, from sensors connected to the computer via the
1347 onewire bus.
1348 * perl plugin: Improved synchronized access to internal data structures
1349 and fixed a possible dead-lock.
1350 * perl plugin: Added the ability to flush certain identifiers and marked
1351 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1352 plugin_flush().
1353 * perl plugin: Added the ability to configure Perl plugins.
1354 * postgresql plugin: The new postgresql plugin collects statistics
1355 about or from a PostgreSQL database.
1356 * processes plugin: The `ProcessMatch' option has been added.
1357 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1358 IO load.
1359 * tcpconns plugin: This plugin has been ported to OpenBSD.
1360 * thermal plugin: The new thermal plugin collects system temperatures
1361 using Linux ACPI thermal zone data.
1363 2009-01-02, Version 4.4.5
1364 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1365 file may be in both locations, especially when the database was
1366 installed in a non-standard path. Thanks to Dusty Doris for
1367 reporting this.
1368 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1369 Solaris, in the configure script automatically.
1370 * collectd.conf(5): Various fixes and clarifications.
1371 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1372 portability problems, especially for Solaris.
1373 * dns plugin: Fix a portability problem with NetBSD.
1374 * network plugin: Fix the handling of `type' in the network protocol.
1375 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1376 much larger buffer. This caused the `type' to be transferred much
1377 more often than necessary. In some cases, e. g. the `cpu' and
1378 `cpufreq' plugins being used at the same time, data may be corrupted
1379 in those files. Thanks to Bruno Prémont for debugging and reporting
1380 this issue.
1381 * unixsock plugin: Make sure the initialization function is run only
1382 once. This resolves a file descriptor leak under systems which run
1383 the initialization more than once, such as Solaris.
1385 2008-10-16, Version 4.4.4
1386 * build system: Change `--enable-<plugin>' to abort with an error if
1387 dependencies are not met. Thanks to Bruno Prémont for the patch.
1388 Also, the poisoning of various string functions has been restricted
1389 to debug builds.
1390 * collectd: Fix a memory leak in the global value cache. With every
1391 *missing* value a couple of bytes would be leaked. Another memory
1392 leak in the configuration handling code has been fixed. Thanks to
1393 Niraj Tolia for reporting these issues.
1394 * collectd: Fix an off-by-one error in the ignorelist functionality.
1395 When using regular expressions, the last character would be missing,
1396 possibly matching differently from what one would expect.
1397 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1398 problem.
1399 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1400 Linzberger for reporting the bug.
1401 * network plugin: Fix a memory leak in the configuration handling
1402 code. Thanks to Niraj Tolia for reporting this issue.
1403 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1404 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1405 problems with some `libc's. Thanks to Matthias Lay for reporting the
1406 bug.
1408 2008-09-01, Version 4.4.3
1409 * collectd: Fix a memory leak in the threshold checking code.
1410 * memcached plugin: Fix a too short timeout and a related file
1411 descriptor leak.
1412 * memory plugin: A typo in the libstatgrab code has been fixed.
1413 * snmp plugin: Fix a possible memory leak.
1415 2008-07-15, Version 4.4.2
1416 * build system: Use pkg-config to detect the upsclient library.
1417 * collectd: Try even harder to determine the endianess of the
1418 architecture collectd is being built on.
1419 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1420 of disks.
1421 * dns plugin: Fix compilation errors with BIND versions 19991001
1422 through 19991005.
1423 * network plugin: Bugfix in the init routine: The init function
1424 cleared a buffer regardless of its contents. This could lead to lost
1425 values under Solaris.
1426 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1427 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1428 function.
1429 * wireless plugin: Work around incorrect noise and power values
1430 returned by some broken drivers.
1432 2008-06-03, Version 4.4.1
1433 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1434 to kyrone for reporting this.
1435 * collectd: Fixed min/max output in notifications generated by
1436 threshold checking.
1437 * collectd-nagios: Fix the protocol used to communicate with the
1438 daemon.
1439 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1440 initialization has errors. An issue with Perl 5.10 has been fixed.
1441 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1442 René Rebe and Siegmund Gorr for reporting this.
1444 2008-05-06, Version 4.4.0
1445 * collectd: Internal code cleanups.
1446 * collectd: Added support for a `Flush' command in the unixsock and
1447 exec plugins. This command can be used to force a plugin (or all) to
1448 flush its values to disk.
1449 * collectd: Thresholds can now be configured to apply to one data
1450 source only, making it possible to configure different thresholds
1451 for each data source.
1452 * apache, nginx plugins: Added the possibility to disable host and/or
1453 peer verification.
1454 * ascent plugin: The new ascent plugin reads and parses the statistics
1455 page of an Ascent server.
1456 * cpu plugin: Support for the statgrab library has been added.
1457 * disk plugin: The possibility to ignore certain disks or collect only
1458 specific disks has been added.
1459 * disk plugin: Support for the statgrab library has been added.
1460 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1461 sensor values via IPMI, the intelligent platform management
1462 interface.
1463 * iptables plugin: The iptc library that is used by the iptables
1464 plugin has been added to the distribution, because it is not
1465 provided by all distributions and removed from at least one.
1466 * powerdns plugin: The new powerdns plugin reads statistics from an
1467 authoritative or a recursing PowerDNS name server.
1468 * rrdtool plugin: The size of the files generated with the default
1469 configuration has been decreased.
1470 * tail plugin: The new tail plugin can be used to gather statistics by
1471 continuously reading from log files.
1472 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1473 TeamSpeak2 server and collects statistics about the number of users
1474 and number of channels.
1475 * users plugin: Support for the statgrab library has been added.
1476 * vmem plugin: The new vmem plugin collects very detailed statistics
1477 about the virtual memory subsystem of Linux.
1479 2008-08-30, Version 4.3.4
1480 * Build system: Improved detection of and linking with the statgrab
1481 library.
1482 * collectd: Portability fixes, especially to determine endianess more
1483 reliable.
1484 * Various plugins: Fix format strings.
1485 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1486 again has been applied.
1487 * memcached plugin: Fix a too short timeout and a related file
1488 descriptor leak.
1489 * memory plugin: A typo in the libstatgrab code has been fixed.
1490 * network plugin: A fix in the initialization function solves problems
1491 under Solaris.
1492 * nginx plugin: A thread-unsafe function has been replaced.
1493 * vserver plugin: A thread-unsafe function has been replaced.
1494 * wireless plugin: A work-around for broken wireless drivers has been
1495 added.
1497 2008-04-22, Version 4.3.3
1498 * build system: Improved detection of several libraries, especially if
1499 they are in non-standard paths.
1500 * build system: Portability fixes: Automatically define "_REENTRANT"
1501 if the libc expects it.
1502 * collectd: Error and warning messages have been improved.
1503 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1504 using them.
1505 * apache plugin: Allocate new memory when reading a webpage instead of
1506 using a buffer of static size.
1507 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1508 the program.
1509 * hddtemp plugin: Error and warning messages have been improved.
1510 * sensors plugin: Fix sensor collection for some chip types.
1512 2008-03-29, Version 4.3.2
1513 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1514 `Persist' threshold options.
1515 * collectd: Fix handling of missing values in the global value cache.
1516 * collectd: Improved error messages when parsing the configuration.
1517 * sensors plugin: Fix temperature collection with libsensors4.
1518 * unixsock plugin: Fix mixed input and output operation on streams.
1519 * wireless plugin: Fix reading noise value.
1521 2008-03-05, Version 4.3.1
1522 * exec plugin: Set supplementary group IDs.
1523 * network plugin:
1524 + Use `memcpy' when constructing/parsing a package to avoid
1525 alignment problems on weird architectures, such as Sparc.
1526 + Translate doubles to/from the x86 byte representation to ensure
1527 cross-platform compatibility.
1528 * ping plugin: Correct the handling of the `TTL' setting.
1529 * swap plugin: Reapply a patch for Solaris.
1530 * tcpconns plugin: Portability improvements.
1532 2008-02-18, Version 4.3.0
1533 * collectd: Notifications have been added to the daemon. Notifications
1534 are status messages that may be associated with a data instance.
1535 * collectd: Threshold checking has been added to the daemon. This
1536 means that you can configure threshold values for each data
1537 instance. If this threshold is exceeded a notification will be
1538 created.
1539 * collectd: The new `FQDNLookup' option tells the daemon to use the
1540 full qualified domain name as the hostname, not just the host part
1541 es returned by `gethostname(2)'.
1542 * collectd: Support for more than one `TypesDB' file has been added.
1543 This is useful when one such file is included in a package but one
1544 wants to add custom type definitions.
1545 * collectd: The `Include' config option has been expanded to handle
1546 entire directories and shell wildcards.
1547 * collectdmon: The new `collectdmon' binary detects when collectd
1548 terminates and automatically restarts it again.
1549 * csv plugin: The CSV plugin is now able to store counter values as a
1550 rate, using the `StoreRates' configuration option.
1551 * exec plugin: Handling of notifications has been added and the
1552 ability to pass arguments to the executed programs has been added.
1553 * hddtemp plugin: The new `TranslateDevicename' option lets you
1554 disable the translation from device names to major-minor-numbers.
1555 * logfile plugin: Handling of notifications has been added.
1556 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1557 domain name lookups in this plugin.
1558 * perl plugin: Many internal changes added support for handling multiple
1559 threads making the plugin reasonably usable inside collectd. The API has
1560 been extended to support notifications and export global variables to
1561 Perl plugins; callbacks now have to be identified by name rather than a
1562 pointer to a subroutine. The plugin is no longer experimental.
1563 * uuid plugin: The new UUID plugin sets the hostname to an unique
1564 identifier for this host. This is meant for setups where each client
1565 may migrate to another physical host, possibly going through one or
1566 more name changes in the process. Thanks to Richard Jones from
1567 Red Hat's Emerging Technology group for this plugin.
1568 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1569 CPU, disk and network statistics about guest systems on the same
1570 physical server. Thanks to Richard Jones from Red Hat's Emerging
1571 Technology group for this plugin.
1573 2008-04-22, Version 4.2.7
1574 * build system: Improved detection of several libraries, especially if
1575 they are in non-standard paths.
1576 * build system: Portability fixes: Automatically define "_REENTRANT"
1577 if the libc expects it.
1578 * collectd: Error and warning messages have been improved.
1579 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1580 using them.
1581 * apache plugin: Allocate new memory when reading a webpage instead of
1582 using a buffer of static size.
1583 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1584 the program.
1585 * hddtemp plugin: Error and warning messages have been improved.
1586 * sensors plugin: Fix sensor collection for some chip types.
1588 2008-03-29, Version 4.2.6
1589 * collectd: Improved error messages when parsing the configuration.
1590 * sensors plugin: Fix temperature collection with libsensors4.
1591 * unixsock plugin: Fix mixed input and output operation on streams.
1592 * wireless plugin: Fix reading noise value.
1594 2008-03-04, Version 4.2.5
1595 * apache plugin: Improved initialization and error messages.
1596 * exec plugin: Set supplementary group IDs.
1597 * network plugin:
1598 + Create separate threads for reading from the socket and parsing
1599 and dispatching incoming packets. Versions prior to this may have
1600 problems in high-load situations, where the socket receive buffers
1601 overflows, resulting in gaps in the data.
1602 + Use `memcpy' when constructing/parsing a package to avoid
1603 alignment problems on weird architectures, such as Sparc.
1604 + Translate doubles to/from the x86 byte representation to ensure
1605 cross-platform compatibility.
1606 * ping plugin: Correct the handling of the `TTL' setting.
1607 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1608 * swap plugin: Reapply a patch for Solaris.
1609 * tcpconns plugin: Portability improvements.
1611 2008-01-21, Version 4.2.4
1612 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1613 the permission on the socket as documented in the manpage. Thanks to
1614 Evgeny Chukreev for fixing this issue.
1615 * collectd: The documentation has been improved.
1617 2007-12-28, Version 4.2.3
1618 * sensors plugin: Updated the plugin to build and work with version 3
1619 of the libsensors library.
1621 2007-12-15, Version 4.2.2
1622 * nginx plugin: Incorrect comparison of strings lead to a segfault
1623 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1624 this.
1625 * logfile plugin: The config option `Timestamp' was handled
1626 incorrectly and basically always active. Thanks to Luke Heberling
1627 for fixing this.
1629 2007-11-08, Version 4.2.1
1630 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1631 enabled on the host.
1632 * snmp plugin: Fix a memory leak.
1634 2007-10-27, Version 4.2.0
1635 * collectd: The new config option `Include' lets you include other
1636 configfiles and thus split up your config into smaller parts. This
1637 may be especially interesting for the snmp plugin to keep the data
1638 definitions separate from the host definitions.
1639 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1640 (number of connections, octets and packets for each service and
1641 destination). Thanks to Sebastian Harl for this plugin.
1642 * memcached plugin: The new `memcached' plugin connects to a memcached
1643 daemon process and collects statistics of this distributed caching
1644 system. Thanks to Antony Dovgal for contributing this plugin.
1645 * nginx plugin: The new `nginx' plugin reads the status page of an
1646 nginx daemon and saves the handled connections and requests.
1647 * perl plugin: Many changes, including the added `EnableDebugger'
1648 config option which lets you debug your Perl plugins more easily.
1649 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1650 be more thread-safe otherwise by locking calls to the library.
1651 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1652 correct the values returned by SNMP-agents. If a <data> block is
1653 defined as `table' the instance is now optional. The sequence number
1654 is used as the type-instance in this case. The new `InstancePrefix'
1655 option allows to add arbitrary prefixes to the type-instance.
1656 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1657 certain TCP connections and what state they're in. This can be used
1658 to see how many connections your FTP server has to handle or how
1659 many outgoing connections your mailserver has open.
1661 2008-01-11, Version 4.1.6
1662 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1663 the permission on the socket as documented in the manpage. Thanks to
1664 Evgeny Chukreev for fixing this issue.
1665 * collectd: The documentation has been improved.
1667 2007-12-27, Version 4.1.5
1668 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1669 memory situations.
1670 * sensors plugin: Updated the plugin to build and work with version 3
1671 of the libsensors library.
1673 2007-11-08, Version 4.1.4
1674 * Build system: Improve detection of the rrd library, especially if
1675 it's in a non-standard location.
1676 * Build system: A bug when parsing the argument for
1677 `--with-libnetsnmp' has been fixed.
1678 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1679 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1680 a deadlock or delay when shutting down the daemon.
1681 * snmp plugin: Fix a memory leak.
1683 2007-10-24, Version 4.1.3
1684 * collectd: A build issue under Solaris has been resolved by renaming
1685 data types.
1686 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1687 be more thread-safe otherwise by locking calls to the library.
1689 2007-09-28, Version 4.1.2
1690 * apcups plugin: Fix reporting of the `load percent' data.
1691 * wireless plugin: Correct the handling of cards returning signal and
1692 noise quality as percentage.
1693 * perl plugin: Fix a possible buffer overflow in get_module_name().
1694 * build system: Further improve the detection of libraries.
1695 * netlink plugin: Build issues under some older versions of the Linux
1696 includes (i. e. Debian Sarge) have been fixed.
1697 * snmp plugin: Fix a potential segfault when a host times out. Add
1698 support for the `timeticks' type.
1700 2007-09-12, Version 4.1.1
1701 * Build system: The detection of `libnetlink' has been improved.
1702 * collectd: The documentation has been fixed in numerous places.
1703 * exec plugin: Setting the group under which to run a program has been
1704 fixed.
1705 * collectd: The `sstrerror' function was improved to work correctly
1706 with the broken GNU version of `strerror_r'.
1707 * collectd: Write an error message to STDERR when loading of a plugin
1708 fails.
1709 * apcups plugin: Fix the `types' used to submit the values: They still
1710 has an `apcups_' prefix which doesn't work anymore.
1711 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1712 whatever the client thinks is `now'..
1714 2007-09-01, Version 4.1.0
1715 * Build system: The build system has been changed to automatically
1716 disable all plugins, which are missing dependencies. The dependency
1717 checking has been removed from the plugins themselves to remove
1718 redundancy.
1719 * Flexible interval: The interval of collected data is now sent along
1720 with the data itself over the network, so that the interval-settings
1721 of server and clients no longer needs to match.
1722 * netlink plugin: The new `netlink' plugin connects to the Linux
1723 kernel using a netlink socket and uses it to query information about
1724 interfaces, qdiscs and classes.
1725 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1726 to not block data collection.
1727 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1728 network devices, such as switches, routers, thermometers, rack
1729 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1730 plugin.
1731 * unixsock plugin: Added the `LISTVAL' command.
1732 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1733 of music played with xmms.
1735 2007-09-28, Version 4.0.9
1736 * apcups plugin: Fix reporting of the `load percent' data.
1737 * wireless plugin: Correct the handling of cards returning signal and
1738 noise quality as percentage.
1739 * perl plugin: Fix a possible buffer overflow in get_module_name().
1741 2007-09-12, Version 4.0.8
1742 * collectd: The `sstrerror' function was improved to work correctly
1743 with the broken GNU version of `strerror_r'.
1744 * collectd: Write an error message to STDERR when loading of a plugin
1745 fails.
1746 * apcups plugin: Fix the `types' used to submit the values: They still
1747 has an `apcups_' prefix which doesn't work anymore.
1748 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1749 whatever the client thinks is `now'..
1751 2007-08-26, Version 4.0.7
1752 * documentation: Some typos have been fixed and some information has
1753 been improved.
1754 * build system: Many fixes for detecting libraries in unusual places,
1755 such as on RedHat systems. The affected libraries are `libcurl',
1756 `libmysql', and `libupsclient'.
1757 * network plugin: Allow the `Port' option to be specified as a number
1758 (i. e. without quotes).
1759 * nut plugin: A fix allows linking the nut plugin against
1760 libupsclient, version >= 2.2.0.
1761 * processes plugin: Fix a potential segmentation fault.
1763 2007-07-30, Version 4.0.6
1764 * sensors plugin: Fix the ignorelist functionality: Only the `type
1765 instance' was used to match against the list, but the documentation
1766 told otherwise. This release fixes the code, so it complies with the
1767 documentation.
1768 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1769 configuration messages will end up in the logging facility.
1770 * conrtib/fedora: The contributed specfile for Fedora has been
1771 updated.
1773 2007-07-05, Version 4.0.5
1774 * Portability: More fixes for OpenBSD have been included.
1776 2007-06-24, Version 4.0.4
1777 * cpu plugin: Fixed the Solaris code.
1778 * dns plugin: Fixed a build issue for OpenBSD.
1779 * interface plugin: Fixed the Solaris code.
1780 * load plugin: Fixed the alternative `/proc' Linux code.
1781 * memory plugin: Fixed the Solaris code.
1782 * oconfig: Don't require `-lfl' anymore.
1784 2007-06-19, Version 4.0.3
1785 * cpu plugin: Fix the Darwin / Mac OS X code.
1786 * ping plugin: Use the return value of `getpid', not its address.
1787 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1788 initialized correctly.
1789 * configure: Added `--with-nan-emulation' to aid cross compilation.
1791 2007-06-12, Version 4.0.2
1792 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1793 they're given in numerically form.
1795 2007-06-07, Version 4.0.1
1796 * iptables plugin: A bug in the configuration routine has been fixed.
1797 Setting a comment in the configfile will no longer cause a
1798 segmentation fault.
1800 2007-06-03, Version 4.0.0
1801 * collectd: The plugin-infrastructure has been changed to allow for
1802 more types of plugins, namely `write' and `log' plugins.
1803 * collectd: The read-function has been changed to read many plugins in
1804 parallel, using threads. Thus, plugins generally need to use
1805 thread-safe functions from now on.
1806 * collectd: The '-t' command line options allows to perform syntax tests
1807 of the configuration file and exit immediately.
1808 * csv plugin: The new `csv' plugin handles output to `comma separated
1809 values'-files.
1810 * rrdtool plugin: The new `rrdtool' plugin handles output to
1811 RRD-files. Data can be cached to combine multiple updates into one
1812 write to increase IO-performance.
1813 * network plugin: The new `network' plugin handles IO via the network.
1814 It implements a different, much more extensible protocol which can
1815 combine many values in one packet, decreasing the number of UDP-
1816 packets being sent. It can read from and send to the network and
1817 with the appropriate configuration even forward packets to other
1818 networks.
1819 * unixsock plugin: The new `unixsock' plugin provides an interface to
1820 communicate with the daemon while it is running. Right now the
1821 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1822 come.
1823 * perl plugin: The new `perl' plugin allows you to write extensions
1824 for collectd in the scripting-language Perl.
1825 * logfile plugin: The new `logfile' plugin writes logmessages to files
1826 or STDOUT or STDERR.
1827 * syslog plugin: The new `syslog' plugin sends logmessages to the
1828 system's syslog daemon.
1829 * entropy plugin: The new `entropy' plugin collects the amount of
1830 entropy currently being available to the system.
1831 * exec plugin: The new `exec' plugin forks child processes and reads
1832 back values provided by the forked processes.
1833 * iptables plugin: The new `iptables' plugin reads counters from
1834 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1835 plugin.
1836 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1837 to Peter Holik for contributing this plugin.
1838 * nut plugin: The new `nut' plugin connects the upsd of the `network
1839 ups tools' and reads information about the connected UPS.
1840 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1841 connections) field was added by Florent Monbillard.
1842 * collectd-nagios: The new `collectd-nagios' binary queries values
1843 from collectd, parses them and exits according to Nagios-standards.
1844 * manpages: The manpages have been improved a lot.
1846 2007-09-28, Version 3.11.7
1847 * wireless plugin: Correct the handling of cards returning signal and
1848 noise quality as percentage.
1850 2007-08-31, Version 3.11.6
1851 * processes plugin: Fix a potential segmentation fault.
1853 2007-05-29, Version 3.11.5
1854 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1855 * ntpd plugin: Fix a potential buffer overflow.
1856 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1857 were accounted as `zombies'.
1859 2007-04-10, Version 3.11.4
1860 * dns plugin: Change the order of includes to make the plugin compile
1861 under FreeBSD.
1863 2007-03-30, Version 3.11.3
1864 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1865 of the unused `COLLECT_KSTAT'.
1867 2007-02-11, Version 3.11.2
1868 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1869 NULL-pointer may have been passed to `printf' which causes a
1870 segfault with some libcs.
1872 2007-02-10, Version 3.11.1
1873 * df plugin: Some wrong defines have been fixed so the plugin works
1874 under Solaris again.
1875 * dns plugin: The usage of a struct has been fixed to work with
1876 non-GNU libcs.
1877 * processes plugin: Some missing defines have been added so the plugin
1878 compiles cleanly under FreeBSD and presumably other UNIXes.
1880 2006-12-22, Version 3.11.0
1881 * collectd: The new command line option `-P' makes it easier for
1882 distributors to change the location of PID-files.
1883 * collectd: The daemon shuts down faster now which makes it easier to
1884 write init.d-scripts for it.
1885 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1886 caused problems every now and then.
1887 * df plugin: New config options allow to ignore certain mountpoints,
1888 filesystem types or devices.
1889 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1890 and interprets it. It collects traffic as well as qtype, opcode and
1891 rcode counts.
1892 * email plugin: Sebastian Harl has contributed this plugin which
1893 counts received mails in categories (e. g. ham, spam, virus), spam
1894 score (as given by SpamAssassin) and check types.
1895 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1896 uses `mbmon' to gather information from sensors on the motherboard.
1897 * processes plugin: Collect detailed statistics for configured
1898 processes, that's process and thread count, CPU usage, resident
1899 segment size and pagefaults.
1900 * multimeter plugin: Peter Holik contributed a new plugin which
1901 queries multimeters.
1902 * sensors plugin: Lubos Stanek has put much effort into improving this
1903 plugin, including `extended naming', collection of voltage values
1904 and the possibility to ignore certain values.
1906 2006-12-21, Version 3.10.4
1907 * Max Kellermann has identified a bug in the server routine: When
1908 opening a socket fails the daemon will (re)try opening the socket in
1909 an endless loop, ultimately leading to a `EMFILE' error.
1911 2006-11-04, Version 3.10.3
1912 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1913 ntpd's reply was sent in more than one packet, the buffer size was
1914 calculated incorrectly, resulting in the reading of uninitialized or
1915 freed memory.
1917 2006-11-01, Version 3.10.2
1918 * The sample config file has been improved.
1919 * Errors in the manpages have been corrected.
1920 * The ping-plugin now adds hosts during initialization, not during
1921 startup. This speeds up startup when no network connectivity is
1922 available. Also, the hosts are being added later when the network is
1923 available.
1924 * Improved BSD-support for the df-plugin.
1925 * Fixed syntax errors in the swap-plugin for Mac OS X.
1926 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1927 plugin.
1928 * Don't disable the mysql-plugin if connecting to the database fails
1929 during initialization. Instead, try again in increasing intervals.
1931 2006-07-19, Version 3.10.1
1932 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1933 the apcups cannot be reached, unconnected sockets will pile up and
1934 eventually lead to `Too many open files' errors.
1936 2006-07-09, Version 3.10.0
1937 * The `disk' plugin has been ported to Darwin.
1938 * The `battery' plugin should work on many Apple computers now.
1939 * The `traffic' plugin can now ignore certain interfaces. Also,
1940 statistics for sent/received packets and errors have been added.
1941 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1942 to Anthony Gialluca for contributing this plugin and providing me
1943 with a test environment :)
1944 * A plugin for monitoring an NTP instance and the local clock drift
1945 has been added.
1947 2006-06-25, Version 3.9.4
1948 * The Solaris code in the `swap' plugin has been changed to reflect
1949 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1950 working this out.
1951 * The debugging system has been fixed to work with the Sun libc.
1952 * When built without librrd the variable `operating_mode' could be
1953 uninitialized. Thanks to David Elliot for reporting the bug.
1955 2006-06-01, Version 3.9.3
1956 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1957 operating systems also profit from the changes, but I wasn't able to
1958 check that.
1959 * Changed the build system to find the netinet-includes under FreeBSD
1960 and therefore successfully build the `liboping' library there.
1962 2006-05-09, Version 3.9.2
1963 * Applied a patch to the `liboping' library. Due to a bug in the
1964 sequence checking the `ping' plugin stopped working after
1965 approximately 7.6 days.
1967 2006-05-09, Version 3.8.5
1968 * Applied a patch to the `liboping' library. Due to a bug in the
1969 sequence checking the `ping' plugin stopped working after
1970 approximately 7.6 days.
1972 2006-04-21, Version 3.9.1
1973 * Build issues with Solaris and possible other architectures have been
1974 resolved.
1975 * Problems when building the `apache'-plugin without `libcurl' have
1976 been resolved.
1977 * A bug in the `ping' plugin has been fixed. Sorry folks.
1979 2006-04-02, Version 3.9.0
1980 * A plugin to monitor the Apache webserver has been added.
1981 <http://httpd.apache.org/>
1982 * A plugin to collect statistics about virtual servers using VServer.
1983 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1984 this plugin :)
1985 * A plugin for wireless LAN cards has been added. It monitors signal
1986 strength, link quality and noise ratio..
1987 * A plugin for Apple hardware sensors has been added.
1988 * An option to compile collectd with different `step' and `heartbeat'
1989 settings has been added. The size of RRAs is no longer static but
1990 calculated based on the settings for `step' and `width'.
1991 * The `ping' plugin can now be configured to use a certain TTL.
1992 * A plugin to monitor the hardware sensors of Apple computers has been
1993 added.
1994 * The plugins `cpu', `memory', `processes' and `traffic' have been
1995 ported to Mach/Darwin (Mac OS X).
1996 * The `log mode' has been contributed by Christophe Kalt. It writes
1997 the data into text files rather than RRD files.
1999 2006-04-09, Version 3.8.4
2000 * Applied patch by Vincent Stehlé which improves the disk-name
2001 resolution in the `hddtemp' plugin for Linux systems.
2003 2006-04-02, Version 3.8.3
2004 * Applied a patch by James Byers: The MySQL plugin was not working
2005 with MySQL 5.0.2 or later.
2007 2006-03-14, Version 3.8.2
2008 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2009 the GNU libc, because it points to `/etc/fstab' rather than
2010 `/etc/mtab'.
2012 2006-03-13, Version 3.8.1
2013 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2014 * Fixes in the debian `postinst' and `init.d' scripts.
2016 2006-03-09, Version 3.8.0
2017 * The `ping' plugin no longer uses `libping' but a self written
2018 library named `liboping'. With this library it's possible to ping
2019 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2021 2006-02-18, Version 3.7.2
2022 * A simple bug in the `battery' plugin has been fixed. It should now
2023 work with ACPI based batteries as well. Thanks to Sebastian for
2024 fixing this.
2025 * Fixing a bug that prevented collectd to be built without librrd.
2026 Thanks to Werner Heuser for reporting it.
2028 2006-02-04, Version 3.7.1
2029 * The new network code has been improved to build with older versions
2030 of glibc.
2031 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2032 to Tommie Gannert for this patch.
2034 2006-01-30, Version 3.7.0
2035 * The `battery' plugin has been added. It collects information about
2036 laptop batteries..
2037 * The MySQL plugin has been improved: It now writes two more RRD
2038 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2039 * The `cpufreq' plugin now reads another file since the file it did
2040 read so far causes much overhead in the kernel. Also, you need root
2041 to read the old file, but not to read the new one.
2042 * The `hddtemp' plugin can now be configured to connect to another
2043 address and/or port than localhost.
2044 * The `df' plugin now prefers `statvfs' over `statfs'.
2045 * The network code has been rewritten. collectd now supports unicast
2046 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2047 be set in the configfile.
2049 2006-01-24, Version 3.6.2
2050 * Due to a bug in the configfile handling collectd wouldn't start in
2051 client mode. This released fixes this.
2053 2006-01-20, Version 3.6.1
2054 * Due to a bug in `configure.in' all modules and the binary were
2055 linked against `libmysqlclient'. This issue is solved by this
2056 release.
2058 2006-01-17, Version 3.6.0
2059 * A config file has been added. This allows for loading only specific
2060 plugins.
2061 * A `df' plugin has been added.
2062 * A `mysql' plugin has been added.
2063 * The `ping' plugin doesn't entirely give up hope when a socket error
2064 occurred, but will back of and increase the intervals between tries.
2066 2006-01-21, Version 3.5.2
2067 * Fixed yet another bug in the signal handling.. Stupid typo..
2068 * Improved the ping plugin to not give up on socket errors (backport
2069 from 3.6.0).
2071 2005-12-18, Version 3.5.1
2072 * The PID-file is now deleted correctly when shutting down the daemon.
2073 * SIGINT and SIGTERM are now handled correctly.
2075 2005-12-16, Version 3.5.0 (Revision 326)
2076 * A bug in the `load' module under Solaris has been fixed.
2077 * The `users' module has been contributed by Sebastian Harl. It counts
2078 currently logged in users.
2079 * The CPU module now works under FreeBSD without the use of
2080 `libstatgrab', however SMP support is missing.
2081 * The default directories for the RRD files and the PID file now
2082 depend on the compile time setting of `localstatedir'.
2084 2005-11-15, Version 3.4.0 (Revision 236)
2085 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2086 from gentoo's bugzilla for writing the patch.
2087 * The build dependency for librrd has been removed. Binaries built
2088 without librrd are client-only and will multicast their value as
2089 with the `-c' argument.
2090 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2091 * The newly introduced `-f' switch prevents daemon initialization
2092 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2093 Barcellos for this patch.
2095 2005-11-04, Version 3.3.0 (Revision 216)
2096 * New modules have been added:
2097 - `serial', for monitoring traffic on the serial interfaces
2098 - `nfs', for graphing NFS procedure calls
2099 - `tape', traffic from/to tape devices
2100 * The memory.rrd now accepts more than 4Gig of memory.
2102 2005-10-26, Version 3.2.0 (Revision 200)
2103 * Support for graphing the processes has been added (thanks to Lyonel
2104 Vincent)
2105 * If reading from hddtemp fails collectd will increase the time
2106 between polls up to one day.
2107 * The init.d files have been improved.
2108 * Problems with the spec file have been fixed.
2110 2005-10-16, Version 3.1.0 (Revision 194)
2111 * Added the `setsid' syscall to the startup code.
2112 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2114 2005-09-30, Version 3.0.0 (Revision 184)
2115 * The ability to send/receive data to/from the network (think
2116 multicast) has been added.
2117 * Modules have been split up into shared libraries can be loaded at
2118 runtime. The biggest advantage is that the core program doesn't need
2119 to be linked against an external library.
2120 * A patch by George Kargiotakis has been applied: It fixes the sensors
2121 behaviour then more than one sensor is being queried.
2123 2005-09-16, Version 2.1.0 (Revision 172)
2124 * A module for swap statistics has been added.
2126 2005-09-09, Version 2.0.0 (Revision 135)
2127 * Filenames can no longer be configured at program startup. The only
2128 options as of this version are the directory and ping hosts.
2129 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2130 Soft-IRQ statistics are added to `System'.
2131 * Diskstats now collect read and write bytes, not sectors.
2132 * Ping statistics can now be collected for more than one host. There
2133 is no default any more: If no host is given no host will be pinged.
2134 * A self-written patch for libping has been applied so it builds
2135 cleanly.
2137 2005-09-01, Version 1.8.1 (Revision 123)
2138 * Much improved configure-script: libraries and features may now be
2139 disabled.
2140 * More detailed warnings/error messages when RRD update fails.
2142 2005-08-29, Version 1.8.0:
2143 * Support for collecting disk statistics under Solaris.
2145 2005-08-25, Version 1.7.0:
2146 * Support for libstatgrab[1] for load, memory usage and network
2147 traffic. CPU- and disk-usage are not (yet) supported, since
2148 libstatgrab returns insufficient information. I will contact the
2149 authors.
2150 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2151 aren't necessarily counted linear which is now handled correctly.
2152 [1]: http://www.i-scream.org/libstatgrab/
2154 2005-08-21, Version 1.6.0:
2155 * Basic support for Solaris: System load and cpu-usage can be
2156 collected under Solaris, too. Other stats will follow later.
2157 * Many fixes in the autoconf-script
2158 * Collection/Museum scripts have been added under contrib/museum
2159 * collectd may now be started in unprivileged mode, though ping
2160 statistics will not work.
2162 2005-07-17, Version 1.5.1:
2163 * Diskstats-RRDs now use major/minor for naming. Some systems have
2164 weird strings as disk-names..
2166 2005-07-17, Version 1.5:
2167 * A new module, diskstats, has been added. It collects information
2168 about the disks and partitions.
2170 2005-07-11, Version 1.4.2:
2171 * The meminfo module has been changed to work with more platforms
2172 and/or kernel versions.
2174 2005-07-10, Version 1.4.1: Correct traffic stats
2175 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2176 forgot to correct when I changed that module.
2178 2005-07-09, Version 1.4: More traffic stats
2179 * Traffic is now collected for all interfaces that can be found
2180 * Temperature-statistics are read from lm-sensors if available
2182 2005-07-08, Version 1.3: CPU stats
2183 * Collecting CPU statistics now
2185 2005-07-12, Version 1.2: Using syslog
2186 * collectd is now using the syslog facility to report errors, warnings
2187 and the like..
2188 * The default directory is now /var/db/collectd
2190 2005-07-10, Version 1.1: Minor changes
2191 * Nothing really useful to say ;)
2193 2005-07-09, Version 1.0: Initial Version
2194 * The following modules are provided:
2195 * Load average
2196 * Ping time
2197 * Traffic
2198 * Memory info
