955 uptime. Thanks to Marco Chiappero for the patch.
957 2009-09-10, Version 4.6.5
958 * collectd: Remove old values when a cache entry is marked as missing.
959 This way the “GETVAL” command of the UnixSock plugin doesn't return
960 old, no longer valid values when this happens. Thanks to Andrés J.
961 Díaz for the patch.
962 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
963 to follow redirects. Thanks to Joey Hess for reporting this bug.
964 * df plugin: Check the ignorelist before stating the file system,
965 possibly reducing the number of stats considerably. Thanks to Joey
966 Hess for reporting this bug.
967 * iptables plugin: Support for the new libiptc API has been added.
968 Thanks to Sebastian Harl for the patch. The build system has been
969 updated to the plugin only includes the shipped header files when it

984 for reporting the bug.
986 2009-06-02, Version 4.6.3
987 * Build system, various plugins: Many build fixes for FreeBSD,
988 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
989 for many fixes and providing a build system for many platforms,
990 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
991 providing an OpenBSD system.
992 * collectd: Two bugs with the threshold checking have been fixed. The
993 first one prevented thresholds to be checked at all, the second one
994 caused wrong behavior with the persistency option. Thanks to Andrés
995 J. Díaz for fixing these problems.
996 * collectd: Handling of the `Include' configuration option has been
997 fixed.
998 * battery plugin: Don't complain about a missing directory every
999 interval.
1000 * exec plugin: Allow executed programs to close STDERR. Thanks to
1001 Thorsten von Eicken for reporting this problem.
1002 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1003 Tomasz Pala for the patch.
1004 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1005 the patch.
1006 * memory plugin: Fix a potential problem under Solaris.
1007 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
1008 to Doug MacEachern for the patch.
1010 2009-03-18, Version 4.6.2
1011 * collectd: Some Solaris utility code has been improved.
1012 * filter subsystem: Allow `Chains' without default targets.
1013 * liboping: A patch to comply with strict aliasing rules has been
1014 added.
1015 * timediff match: Fix a typo: The match was registered with a wrong
1016 name which prevented this match to be used as documented. Thanks to
1017 Bruno Prémont for finding this problem.
1018 * bind plugin: Fix collection of the cached RR sets. The number of RR
1019 sets currently in the cache was collected as a counter value, which
1020 is nonsense. Thanks to Bruno Prémont for implementing this.
1021 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1022 primarily BSDs, don't take it well and crash.
1023 * oracle plugin: Portability to 64 bit systems has been improved.
1024 * postgresql plugin: The default configuration has been improved.
1025 * rrdtool plugin: Fix a possible race condition: If the network plugin
1026 is brought and dispatches a value before the rrdtool plugin is
1027 initialized, the daemon may crash.
1029 2009-02-22, Version 4.6.1
1030 * collectd: Many documentation fixes.
1031 * Collectd::Unixsock: Error handling has been improved.
1032 * regex match: Don't link with the PCRE library.
1033 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1034 for finding and fixing most of them.
1035 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1036 faults. Thanks to Peter Holik for his patch.
1038 2009-02-16, Version 4.6.0
1039 * collectd: Added the `filter chain' infrastructure, which allows the
1040 user to use `matches' and `targets' to control value processing.
1041 * collectd: The new `-T' command line argument allows more in-depth
1042 testing of a configuration. Thanks to Doug MacEachern for the patch.
1043 * collectd-nagios: The Nagios integration command has been updated to
1044 use libcollectdclient. The `percentage' aggregation function has
1045 been added. Thanks to Fabian Linzberger for the patch.
1046 * libcollectdclient: A library which abstracts communication with the
1047 unixsock plugin for clients has been added.
1048 * regex match: Match values by their identifies using regular
1049 expressions.
1050 * timediff match: Match for values with an invalid timestamp.
1051 * value match: Select values by their data sources' values.
1052 * notification target: Create and dispatch a notification.
1053 * replace target: Replace parts of an identifier using regular
1054 expressions.
1055 * set target: Set (overwrite) entire parts of an identifier.
1056 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1057 statistics, allowing very detailed name server statistics. Thanks to
1058 Bruno Prémont for this plugin.
1059 * cpu plugin: Report `interrupt' separately when using
1060 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1061 example for native OpenBSD support, has been added. Thanks to Simon
1062 Kuhnle for the patch.
1063 * csv plugin: Make it possible to write values to STDOUT instead of
1064 files. This is meant for testing purposes mostly. The output written
1065 to STDOUT is compatible with the exec plugin. Thanks to Doug
1066 MacEachern for the patch.
1067 * curl plugin: This new plugin can be used to read web pages and parse
1068 them using the same mechanism that's used in the tail plugin.
1069 * dbi plugin: This new plugin allows you to connect to a variety of
1070 relational databases and use SQL to gather custom statistics from
1071 it. It is similar to the already existing PostgreSQL plugin but uses
1072 libdbi to communicate with the database(s).
1073 * interface plugin: Use the ignorelist framework when selecting /
1074 ignoring interfaces. This allows one to use regular expressions to
1075 select interfaces, too.
1076 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1077 Thanks to Bruno Prémont for this patch.
1078 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1079 for the patch.

1081 socket, too. Thanks to Mirko Buffoni for the patch.
1082 * network plugin: Further performance improvements for the receive
1083 code. This hopefully will help very large setups.
1084 * openvpn plugin: This new plugin collects statistics provided by the
1085 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1086 * oracle plugin: This new plugin allows you to connect to an Oracle
1087 database and use SQL to gather custom statistics from it. It is
1088 similar to the already existing PostgreSQL plugin.
1089 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1090 have been added.
1091 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1092 * perl plugin: Added support for `notification meta data'.
1093 * perl plugin: Added support for the `filter chain' infrastructure by
1094 allowing plugins to register `matches' and `targets'.
1095 * postgresql plugin: The preferred configuration syntax has been
1096 updated to be in line with the syntax used by the new dbi and oracle
1097 plugins. The compatibility code for the old syntax is present.
1098 Support for the new `Result' blocks and the interval parameter has
1099 been added.
1100 * processes plugin: Stacksize and virtual memory usage statistics have
1101 been added. Portability fixes.
1102 * rrdcached plugin: This new plugin uses the (still in development)
1103 RRD accelerator daemon, rrdcached. This daemon works very similar to
1104 the original rrdtool plugin of collectd, but adds some more nice
1105 features.
1106 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1107 added.
1109 2009-05-09, Version 4.5.4
1110 * Build system, various plugins: Many build fixes for FreeBSD,
1111 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1112 for many fixes and providing a build system for many platforms,
1113 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1114 providing an OpenBSD system.
1115 * collectd: Fix a potential race condition when creating directories.
1116 * battery plugin: Don't complain about a missing directory every
1117 interval.
1118 * dns plugin: Slight portability fixes.
1119 * exec plugin: Allow executed programs to close STDERR. Thanks to
1120 Thorsten von Eicken for reporting this problem.
1121 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1122 Tomasz Pala for the patch.
1123 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1124 the patch.
1125 * rrdtool plugin: Fix a possible race condition: If the network plugin
1126 is initialized and dispatches a value before the rrdtool plugin is
1127 initialized, the daemon may crash.
1128 * memory plugin: Fix a potential problem under Solaris.
1130 2009-02-22, Version 4.5.3
1131 * build system: The check for libupsclient even when `pkg-config' is
1132 not available.
1133 * collectd: Fix error handling in the global cache.
1134 * Collectd::Unixsock: Error handling has been improved.
1135 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1136 patch.
1137 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1138 faults. Thanks to Peter Holik for his patch.
1139 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1140 code. Thanks to "thated" for reporting this.
1142 2009-01-02, Version 4.5.2
1143 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1144 file may be in both locations, especially when the database was
1145 installed in a non-standard path. Thanks to Dusty Doris for
1146 reporting this.
1147 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1148 Solaris, in the configure script automatically.
1149 * build system, tcpconns plugin: Check for `kvm_nlist' and
1150 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1151 library with similar functions to the BSD variant, but doesn't
1152 provide these necessary functions.
1153 * collectd.conf(5): Various fixes and clarifications.
1154 * collectd: Remove a GNUism (unnamed unions), thus improving
1155 portability.
1156 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1157 This solves portability problems, especially for Solaris.
1158 * dns plugin: Fix a portability problem with NetBSD.
1159 * filecount plugin: Fix an off-by-one error. This error may cause a
1160 segmentation fault.
1161 * network plugin: Fix the handling of `type' in the network protocol.
1162 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1163 much larger buffer. This caused the `type' to be transferred much
1164 more often than necessary. In some cases, e. g. the `cpu' and
1165 `cpufreq' plugins being used at the same time, data may be corrupted
1166 in those files. Thanks to Bruno Prémont for debugging and reporting
1167 this issue.
1168 * processes plugin: Fix a possible segmentation fault when specifying
1169 invalid configuration options.
1170 * unixsock plugin: Make sure the initialization function is run only
1171 once. This resolves a file descriptor leak under systems which run
1172 the initialization more than once, such as Solaris.
1174 2008-10-16, Version 4.5.1
1175 * build system: Change `--enable-<plugin>' to abort with an error if
1176 dependencies are not met. Thanks to Bruno Prémont for the patch.
1177 Also, the poisoning of various string functions has been restricted
1178 to debug builds.
1179 * collectd: Fix a memory leak in the global value cache. With every
1180 *missing* value a couple of bytes would be leaked. Another memory
1181 leak in the configuration handling code has been fixed. Thanks to
1182 Niraj Tolia for reporting these issues.
1183 * collectd: Fix an off-by-one error in the ignorelist functionality.
1184 When using regular expressions, the last character would be missing,
1185 possibly matching differently from what one would expect.
1186 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1187 problem.
1188 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1189 Linzberger for reporting the bug.
1190 * iptables plugin: Fix an off-by-one error. If a string was just one
1191 character too long, it was truncated instead of reporting an error.
1192 * network plugin: Fix a memory leak in the configuration handling
1193 code. Thanks to Niraj Tolia for reporting this issue.
1194 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1195 * postgresql plugin: Don't reopen connection during reinitialization.
1196 This fixes a bug under Solaris and potentially other platforms.
1197 Missing calls to `PQclear' have been added, too. This fixes memory
1198 leaks. Thanks to ``Admin'' for reporting these bugs.
1199 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1200 library.
1201 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1202 problems with some `libc's. Thanks to Matthias Lay for reporting the
1203 bug.
1205 2008-09-04, Version 4.5.0
1206 * collectd: Added the ability to flush certain identifiers.
1207 * collectd: The concept of `notification meta data' has been
1208 introduced.
1209 * filecount plugin: The new filecount plugin counts the number of
1210 files in a directory and its subdirectories.
1211 * ipmi plugin: Sensor names have been changed to ensure unique names.
1212 Notifications upon added and removed sensors can now be generated.
1213 * notify_desktop plugin: This new plugin sends notifications to the
1214 X desktop using the structure defined in the `Desktop Notification
1215 Specification'.
1216 * notify_email plugin: This new plugin sends out notifications via
1217 email, using the `esmtp' library.
1218 * onewire plugin: The new experimental(!) onewire plugin reads values,
1219 such as temperatures, from sensors connected to the computer via the
1220 onewire bus.
1221 * perl plugin: Improved synchronized access to internal data structures
1222 and fixed a possible dead-lock.
1223 * perl plugin: Added the ability to flush certain identifiers and marked
1224 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1225 plugin_flush().
1226 * perl plugin: Added the ability to configure Perl plugins.
1227 * postgresql plugin: The new postgresql plugin collects statistics
1228 about or from a PostgreSQL database.
1229 * processes plugin: The `ProcessMatch' option has been added.
1230 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1231 IO load.
1232 * tcpconns plugin: This plugin has been ported to OpenBSD.
1233 * thermal plugin: The new thermal plugin collects system temperatures
1234 using Linux ACPI thermal zone data.
1236 2009-01-02, Version 4.4.5
1237 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1238 file may be in both locations, especially when the database was
1239 installed in a non-standard path. Thanks to Dusty Doris for
1240 reporting this.
1241 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1242 Solaris, in the configure script automatically.
1243 * collectd.conf(5): Various fixes and clarifications.
1244 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1245 portability problems, especially for Solaris.
1246 * dns plugin: Fix a portability problem with NetBSD.
1247 * network plugin: Fix the handling of `type' in the network protocol.
1248 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1249 much larger buffer. This caused the `type' to be transferred much
1250 more often than necessary. In some cases, e. g. the `cpu' and
1251 `cpufreq' plugins being used at the same time, data may be corrupted
1252 in those files. Thanks to Bruno Prémont for debugging and reporting
1253 this issue.
1254 * unixsock plugin: Make sure the initialization function is run only
1255 once. This resolves a file descriptor leak under systems which run
1256 the initialization more than once, such as Solaris.
1258 2008-10-16, Version 4.4.4
1259 * build system: Change `--enable-<plugin>' to abort with an error if
1260 dependencies are not met. Thanks to Bruno Prémont for the patch.
1261 Also, the poisoning of various string functions has been restricted
1262 to debug builds.
1263 * collectd: Fix a memory leak in the global value cache. With every
1264 *missing* value a couple of bytes would be leaked. Another memory
1265 leak in the configuration handling code has been fixed. Thanks to
1266 Niraj Tolia for reporting these issues.
1267 * collectd: Fix an off-by-one error in the ignorelist functionality.
1268 When using regular expressions, the last character would be missing,
1269 possibly matching differently from what one would expect.
1270 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1271 problem.
1272 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1273 Linzberger for reporting the bug.
1274 * network plugin: Fix a memory leak in the configuration handling
1275 code. Thanks to Niraj Tolia for reporting this issue.
1276 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1277 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1278 problems with some `libc's. Thanks to Matthias Lay for reporting the
1279 bug.

1290 * collectd: Try even harder to determine the endianess of the
1291 architecture collectd is being built on.
1292 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1293 of disks.
1294 * dns plugin: Fix compilation errors with BIND versions 19991001
1295 through 19991005.
1296 * network plugin: Bugfix in the init routine: The init function
1297 cleared a buffer regardless of its contents. This could lead to lost
1298 values under Solaris.
1299 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1300 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1301 function.
1302 * wireless plugin: Work around incorrect noise and power values
1303 returned by some broken drivers.
1305 2008-06-03, Version 4.4.1
1306 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1307 to kyrone for reporting this.
1308 * collectd: Fixed min/max output in notifications generated by
1309 threshold checking.
1310 * collectd-nagios: Fix the protocol used to communicate with the
1311 daemon.
1312 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1313 initialization has errors. An issue with Perl 5.10 has been fixed.
1314 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1315 René Rebe and Siegmund Gorr for reporting this.
1317 2008-05-06, Version 4.4.0
1318 * collectd: Internal code cleanups.
1319 * collectd: Added support for a `Flush' command in the unixsock and
1320 exec plugins. This command can be used to force a plugin (or all) to
1321 flush its values to disk.
1322 * collectd: Thresholds can now be configured to apply to one data
1323 source only, making it possible to configure different thresholds
1324 for each data source.
1325 * apache, nginx plugins: Added the possibility to disable host and/or
1326 peer verification.
1327 * ascent plugin: The new ascent plugin reads and parses the statistics

1334 sensor values via IPMI, the intelligent platform management
1335 interface.
1336 * iptables plugin: The iptc library that is used by the iptables
1337 plugin has been added to the distribution, because it is not
1338 provided by all distributions and removed from at least one.
1339 * powerdns plugin: The new powerdns plugin reads statistics from an
1340 authoritative or a recursing PowerDNS name server.
1341 * rrdtool plugin: The size of the files generated with the default
1342 configuration has been decreased.

1372 they are in non-standard paths.
1373 * build system: Portability fixes: Automatically define "_REENTRANT"
1374 if the libc expects it.
1375 * collectd: Error and warning messages have been improved.
1376 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1377 using them.
1378 * apache plugin: Allocate new memory when reading a webpage instead of
1379 using a buffer of static size.
1380 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1381 the program.
1382 * hddtemp plugin: Error and warning messages have been improved.
1383 * sensors plugin: Fix sensor collection for some chip types.
1385 2008-03-29, Version 4.3.2
1386 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1387 `Persist' threshold options.
1388 * collectd: Fix handling of missing values in the global value cache.
1389 * collectd: Improved error messages when parsing the configuration.
1390 * sensors plugin: Fix temperature collection with libsensors4.
1391 * unixsock plugin: Fix mixed input and output operation on streams.
1392 * wireless plugin: Fix reading noise value.
1394 2008-03-05, Version 4.3.1
1395 * exec plugin: Set supplementary group IDs.
1396 * network plugin:
1397 + Use `memcpy' when constructing/parsing a package to avoid
1398 alignment problems on weird architectures, such as Sparc.
1399 + Translate doubles to/from the x86 byte representation to ensure
1400 cross-platform compatibility.
1401 * ping plugin: Correct the handling of the `TTL' setting.
1402 * swap plugin: Reapply a patch for Solaris.
1403 * tcpconns plugin: Portability improvements.
1405 2008-02-18, Version 4.3.0
1406 * collectd: Notifications have been added to the daemon. Notifications
1407 are status messages that may be associated with a data instance.
1408 * collectd: Threshold checking has been added to the daemon. This
1409 means that you can configure threshold values for each data
1410 instance. If this threshold is exceeded a notification will be
1411 created.
1412 * collectd: The new `FQDNLookup' option tells the daemon to use the
1413 full qualified domain name as the hostname, not just the host part
1414 es returned by `gethostname(2)'.
1415 * collectd: Support for more than one `TypesDB' file has been added.
1416 This is useful when one such file is included in a package but one
1417 wants to add custom type definitions.
1418 * collectd: The `Include' config option has been expanded to handle
1419 entire directories and shell wildcards.
1420 * collectdmon: The new `collectdmon' binary detects when collectd
1421 terminates and automatically restarts it again.
1422 * csv plugin: The CSV plugin is now able to store counter values as a
1423 rate, using the `StoreRates' configuration option.
1424 * exec plugin: Handling of notifications has been added and the
1425 ability to pass arguments to the executed programs has been added.
1426 * hddtemp plugin: The new `TranslateDevicename' option lets you
1427 disable the translation from device names to major-minor-numbers.
1428 * logfile plugin: Handling of notifications has been added.
1429 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1430 domain name lookups in this plugin.
1431 * perl plugin: Many internal changes added support for handling multiple
1432 threads making the plugin reasonably usable inside collectd. The API has
1433 been extended to support notifications and export global variables to
1434 Perl plugins; callbacks now have to be identified by name rather than a
1435 pointer to a subroutine. The plugin is no longer experimental.
1436 * uuid plugin: The new UUID plugin sets the hostname to an unique
1437 identifier for this host. This is meant for setups where each client
1438 may migrate to another physical host, possibly going through one or
1439 more name changes in the process. Thanks to Richard Jones from
1440 Red Hat's Emerging Technology group for this plugin.
1441 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1442 CPU, disk and network statistics about guest systems on the same
1443 physical server. Thanks to Richard Jones from Red Hat's Emerging
1444 Technology group for this plugin.
1446 2008-04-22, Version 4.2.7
1447 * build system: Improved detection of several libraries, especially if
1448 they are in non-standard paths.
1449 * build system: Portability fixes: Automatically define "_REENTRANT"
1450 if the libc expects it.
1451 * collectd: Error and warning messages have been improved.
1452 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1453 using them.
1454 * apache plugin: Allocate new memory when reading a webpage instead of
1455 using a buffer of static size.
1456 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1457 the program.
1458 * hddtemp plugin: Error and warning messages have been improved.
1459 * sensors plugin: Fix sensor collection for some chip types.
1461 2008-03-29, Version 4.2.6
1462 * collectd: Improved error messages when parsing the configuration.
1463 * sensors plugin: Fix temperature collection with libsensors4.
1464 * unixsock plugin: Fix mixed input and output operation on streams.
1465 * wireless plugin: Fix reading noise value.
1467 2008-03-04, Version 4.2.5
1468 * apache plugin: Improved initialization and error messages.
1469 * exec plugin: Set supplementary group IDs.
1470 * network plugin:
1471 + Create separate threads for reading from the socket and parsing
1472 and dispatching incoming packets. Versions prior to this may have
1473 problems in high-load situations, where the socket receive buffers
1474 overflows, resulting in gaps in the data.
1475 + Use `memcpy' when constructing/parsing a package to avoid
1476 alignment problems on weird architectures, such as Sparc.
1477 + Translate doubles to/from the x86 byte representation to ensure
1478 cross-platform compatibility.
1479 * ping plugin: Correct the handling of the `TTL' setting.
1480 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1481 * swap plugin: Reapply a patch for Solaris.
1482 * tcpconns plugin: Portability improvements.
1484 2008-01-21, Version 4.2.4
1485 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1486 the permission on the socket as documented in the manpage. Thanks to
1487 Evgeny Chukreev for fixing this issue.
1488 * collectd: The documentation has been improved.
1490 2007-12-28, Version 4.2.3
1491 * sensors plugin: Updated the plugin to build and work with version 3
1492 of the libsensors library.
1494 2007-12-15, Version 4.2.2
1495 * nginx plugin: Incorrect comparison of strings lead to a segfault
1496 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1497 this.
1498 * logfile plugin: The config option `Timestamp' was handled
1499 incorrectly and basically always active. Thanks to Luke Heberling
1500 for fixing this.
1502 2007-11-08, Version 4.2.1
1503 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1504 enabled on the host.
1505 * snmp plugin: Fix a memory leak.
1507 2007-10-27, Version 4.2.0
1508 * collectd: The new config option `Include' lets you include other
1509 configfiles and thus split up your config into smaller parts. This
1510 may be especially interesting for the snmp plugin to keep the data
1511 definitions separate from the host definitions.
1512 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1513 (number of connections, octets and packets for each service and
1514 destination). Thanks to Sebastian Harl for this plugin.
1515 * memcached plugin: The new `memcached' plugin connects to a memcached
1516 daemon process and collects statistics of this distributed caching
1517 system. Thanks to Antony Dovgal for contributing this plugin.
1518 * nginx plugin: The new `nginx' plugin reads the status page of an
1519 nginx daemon and saves the handled connections and requests.
1520 * perl plugin: Many changes, including the added `EnableDebugger'
1521 config option which lets you debug your Perl plugins more easily.
1522 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1523 be more thread-safe otherwise by locking calls to the library.
1524 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1525 correct the values returned by SNMP-agents. If a <data> block is
1526 defined as `table' the instance is now optional. The sequence number
1527 is used as the type-instance in this case. The new `InstancePrefix'
1528 option allows to add arbitrary prefixes to the type-instance.
1529 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1530 certain TCP connections and what state they're in. This can be used
1531 to see how many connections your FTP server has to handle or how
1532 many outgoing connections your mailserver has open.
1534 2008-01-11, Version 4.1.6
1535 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1536 the permission on the socket as documented in the manpage. Thanks to
1537 Evgeny Chukreev for fixing this issue.
1538 * collectd: The documentation has been improved.
1540 2007-12-27, Version 4.1.5
1541 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1542 memory situations.
1543 * sensors plugin: Updated the plugin to build and work with version 3
1544 of the libsensors library.
1546 2007-11-08, Version 4.1.4
1547 * Build system: Improve detection of the rrd library, especially if
1548 it's in a non-standard location.
1549 * Build system: A bug when parsing the argument for
1550 `--with-libnetsnmp' has been fixed.
1551 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1552 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1553 a deadlock or delay when shutting down the daemon.
1554 * snmp plugin: Fix a memory leak.
1556 2007-10-24, Version 4.1.3
1557 * collectd: A build issue under Solaris has been resolved by renaming
1558 data types.
1559 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1560 be more thread-safe otherwise by locking calls to the library.
1562 2007-09-28, Version 4.1.2
1563 * apcups plugin: Fix reporting of the `load percent' data.
1564 * wireless plugin: Correct the handling of cards returning signal and
1565 noise quality as percentage.
1566 * perl plugin: Fix a possible buffer overflow in get_module_name().
1567 * build system: Further improve the detection of libraries.
1568 * netlink plugin: Build issues under some older versions of the Linux
1569 includes (i. e. Debian Sarge) have been fixed.
1570 * snmp plugin: Fix a potential segfault when a host times out. Add
1571 support for the `timeticks' type.
1573 2007-09-12, Version 4.1.1
1574 * Build system: The detection of `libnetlink' has been improved.
1575 * collectd: The documentation has been fixed in numerous places.
1576 * exec plugin: Setting the group under which to run a program has been
1577 fixed.
1578 * collectd: The `sstrerror' function was improved to work correctly
1579 with the broken GNU version of `strerror_r'.
1580 * collectd: Write an error message to STDERR when loading of a plugin
1581 fails.
1582 * apcups plugin: Fix the `types' used to submit the values: They still
1583 has an `apcups_' prefix which doesn't work anymore.
1584 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1585 whatever the client thinks is `now'..
1587 2007-09-01, Version 4.1.0
1588 * Build system: The build system has been changed to automatically
1589 disable all plugins, which are missing dependencies. The dependency
1590 checking has been removed from the plugins themselves to remove
1591 redundancy.
1592 * Flexible interval: The interval of collected data is now sent along
1593 with the data itself over the network, so that the interval-settings
1594 of server and clients no longer needs to match.
1595 * netlink plugin: The new `netlink' plugin connects to the Linux
1596 kernel using a netlink socket and uses it to query information about
1597 interfaces, qdiscs and classes.
1598 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1599 to not block data collection.
1600 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1601 network devices, such as switches, routers, thermometers, rack
1602 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1603 plugin.
1604 * unixsock plugin: Added the `LISTVAL' command.
1605 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1606 of music played with xmms.
1608 2007-09-28, Version 4.0.9
1609 * apcups plugin: Fix reporting of the `load percent' data.
1610 * wireless plugin: Correct the handling of cards returning signal and
1611 noise quality as percentage.
1612 * perl plugin: Fix a possible buffer overflow in get_module_name().
1614 2007-09-12, Version 4.0.8
1615 * collectd: The `sstrerror' function was improved to work correctly
1616 with the broken GNU version of `strerror_r'.
1617 * collectd: Write an error message to STDERR when loading of a plugin
1618 fails.
1619 * apcups plugin: Fix the `types' used to submit the values: They still
1620 has an `apcups_' prefix which doesn't work anymore.
1621 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1622 whatever the client thinks is `now'..
1624 2007-08-26, Version 4.0.7
1625 * documentation: Some typos have been fixed and some information has
1626 been improved.
1627 * build system: Many fixes for detecting libraries in unusual places,
1628 such as on RedHat systems. The affected libraries are `libcurl',
1629 `libmysql', and `libupsclient'.
1630 * network plugin: Allow the `Port' option to be specified as a number
1631 (i. e. without quotes).
1632 * nut plugin: A fix allows linking the nut plugin against
1633 libupsclient, version >= 2.2.0.
1634 * processes plugin: Fix a potential segmentation fault.
1636 2007-07-30, Version 4.0.6
1637 * sensors plugin: Fix the ignorelist functionality: Only the `type
1638 instance' was used to match against the list, but the documentation
1639 told otherwise. This release fixes the code, so it complies with the
1640 documentation.
1641 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1642 configuration messages will end up in the logging facility.
1643 * conrtib/fedora: The contributed specfile for Fedora has been
1644 updated.
1646 2007-07-05, Version 4.0.5
1647 * Portability: More fixes for OpenBSD have been included.
1649 2007-06-24, Version 4.0.4
1650 * cpu plugin: Fixed the Solaris code.
1651 * dns plugin: Fixed a build issue for OpenBSD.
1652 * interface plugin: Fixed the Solaris code.
1653 * load plugin: Fixed the alternative `/proc' Linux code.
1654 * memory plugin: Fixed the Solaris code.
1655 * oconfig: Don't require `-lfl' anymore.
1657 2007-06-19, Version 4.0.3
1658 * cpu plugin: Fix the Darwin / Mac OS X code.
1659 * ping plugin: Use the return value of `getpid', not its address.
1660 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1661 initialized correctly.
1662 * configure: Added `--with-nan-emulation' to aid cross compilation.
1664 2007-06-12, Version 4.0.2
1665 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1666 they're given in numerically form.
1668 2007-06-07, Version 4.0.1
1669 * iptables plugin: A bug in the configuration routine has been fixed.
1670 Setting a comment in the configfile will no longer cause a
1671 segmentation fault.
1673 2007-06-03, Version 4.0.0
1674 * collectd: The plugin-infrastructure has been changed to allow for
1675 more types of plugins, namely `write' and `log' plugins.
1676 * collectd: The read-function has been changed to read many plugins in
1677 parallel, using threads. Thus, plugins generally need to use
1678 thread-safe functions from now on.
1679 * collectd: The '-t' command line options allows to perform syntax tests
1680 of the configuration file and exit immediately.
1681 * csv plugin: The new `csv' plugin handles output to `comma separated
1682 values'-files.
1683 * rrdtool plugin: The new `rrdtool' plugin handles output to
1684 RRD-files. Data can be cached to combine multiple updates into one
1685 write to increase IO-performance.
1686 * network plugin: The new `network' plugin handles IO via the network.
1687 It implements a different, much more extensible protocol which can
1688 combine many values in one packet, decreasing the number of UDP-
1689 packets being sent. It can read from and send to the network and
1690 with the appropriate configuration even forward packets to other
1691 networks.
1692 * unixsock plugin: The new `unixsock' plugin provides an interface to
1693 communicate with the daemon while it is running. Right now the
1694 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1695 come.
1696 * perl plugin: The new `perl' plugin allows you to write extensions
1697 for collectd in the scripting-language Perl.
1698 * logfile plugin: The new `logfile' plugin writes logmessages to files
1699 or STDOUT or STDERR.
1700 * syslog plugin: The new `syslog' plugin sends logmessages to the
1701 system's syslog daemon.
1702 * entropy plugin: The new `entropy' plugin collects the amount of
1703 entropy currently being available to the system.
1704 * exec plugin: The new `exec' plugin forks child processes and reads
1705 back values provided by the forked processes.
1706 * iptables plugin: The new `iptables' plugin reads counters from
1707 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1708 plugin.
1709 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1710 to Peter Holik for contributing this plugin.
1711 * nut plugin: The new `nut' plugin connects the upsd of the `network
1712 ups tools' and reads information about the connected UPS.
1713 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1714 connections) field was added by Florent Monbillard.
1715 * collectd-nagios: The new `collectd-nagios' binary queries values
1716 from collectd, parses them and exits according to Nagios-standards.
1717 * manpages: The manpages have been improved a lot.
1719 2007-09-28, Version 3.11.7
1720 * wireless plugin: Correct the handling of cards returning signal and
1721 noise quality as percentage.
1723 2007-08-31, Version 3.11.6
1724 * processes plugin: Fix a potential segmentation fault.
1726 2007-05-29, Version 3.11.5
1727 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1728 * ntpd plugin: Fix a potential buffer overflow.
1729 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1730 were accounted as `zombies'.
1732 2007-04-10, Version 3.11.4
1733 * dns plugin: Change the order of includes to make the plugin compile
1734 under FreeBSD.
1736 2007-03-30, Version 3.11.3
1737 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1738 of the unused `COLLECT_KSTAT'.
1740 2007-02-11, Version 3.11.2
1741 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1742 NULL-pointer may have been passed to `printf' which causes a
1743 segfault with some libcs.
1745 2007-02-10, Version 3.11.1
1746 * df plugin: Some wrong defines have been fixed so the plugin works
1747 under Solaris again.
1748 * dns plugin: The usage of a struct has been fixed to work with
1749 non-GNU libcs.
1750 * processes plugin: Some missing defines have been added so the plugin
1751 compiles cleanly under FreeBSD and presumably other UNIXes.
1753 2006-12-22, Version 3.11.0
1754 * collectd: The new command line option `-P' makes it easier for
1755 distributors to change the location of PID-files.
1756 * collectd: The daemon shuts down faster now which makes it easier to
1757 write init.d-scripts for it.
1758 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1759 caused problems every now and then.
1760 * df plugin: New config options allow to ignore certain mountpoints,
1761 filesystem types or devices.
1762 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1763 and interprets it. It collects traffic as well as qtype, opcode and
1764 rcode counts.
1765 * email plugin: Sebastian Harl has contributed this plugin which
1766 counts received mails in categories (e. g. ham, spam, virus), spam
1767 score (as given by SpamAssassin) and check types.
1768 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1769 uses `mbmon' to gather information from sensors on the motherboard.
1770 * processes plugin: Collect detailed statistics for configured
1771 processes, that's process and thread count, CPU usage, resident
1772 segment size and pagefaults.
1773 * multimeter plugin: Peter Holik contributed a new plugin which
1774 queries multimeters.
1775 * sensors plugin: Lubos Stanek has put much effort into improving this
1776 plugin, including `extended naming', collection of voltage values
1777 and the possibility to ignore certain values.
1779 2006-12-21, Version 3.10.4
1780 * Max Kellermann has identified a bug in the server routine: When
1781 opening a socket fails the daemon will (re)try opening the socket in
1782 an endless loop, ultimately leading to a `EMFILE' error.
1784 2006-11-04, Version 3.10.3
1785 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1786 ntpd's reply was sent in more than one packet, the buffer size was
1787 calculated incorrectly, resulting in the reading of uninitialized or
1788 freed memory.
1790 2006-11-01, Version 3.10.2
1791 * The sample config file has been improved.
1792 * Errors in the manpages have been corrected.
1793 * The ping-plugin now adds hosts during initialization, not during
1794 startup. This speeds up startup when no network connectivity is
1795 available. Also, the hosts are being added later when the network is
1796 available.
1797 * Improved BSD-support for the df-plugin.
1798 * Fixed syntax errors in the swap-plugin for Mac OS X.
1799 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1800 plugin.
1801 * Don't disable the mysql-plugin if connecting to the database fails
1802 during initialization. Instead, try again in increasing intervals.
1804 2006-07-19, Version 3.10.1
1805 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1806 the apcups cannot be reached, unconnected sockets will pile up and
1807 eventually lead to `Too many open files' errors.
1809 2006-07-09, Version 3.10.0
1810 * The `disk' plugin has been ported to Darwin.
1811 * The `battery' plugin should work on many Apple computers now.
1812 * The `traffic' plugin can now ignore certain interfaces. Also,
1813 statistics for sent/received packets and errors have been added.
1814 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1815 to Anthony Gialluca for contributing this plugin and providing me
1816 with a test environment :)
1817 * A plugin for monitoring an NTP instance and the local clock drift
1818 has been added.
1820 2006-06-25, Version 3.9.4
1821 * The Solaris code in the `swap' plugin has been changed to reflect
1822 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1823 working this out.
1824 * The debugging system has been fixed to work with the Sun libc.
1825 * When built without librrd the variable `operating_mode' could be
1826 uninitialized. Thanks to David Elliot for reporting the bug.
1828 2006-06-01, Version 3.9.3
1829 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1830 operating systems also profit from the changes, but I wasn't able to
1831 check that.
1832 * Changed the build system to find the netinet-includes under FreeBSD
1833 and therefore successfully build the `liboping' library there.
1835 2006-05-09, Version 3.9.2
1836 * Applied a patch to the `liboping' library. Due to a bug in the
1837 sequence checking the `ping' plugin stopped working after
1838 approximately 7.6 days.
1840 2006-05-09, Version 3.8.5
1841 * Applied a patch to the `liboping' library. Due to a bug in the
1842 sequence checking the `ping' plugin stopped working after
1843 approximately 7.6 days.
1845 2006-04-21, Version 3.9.1
1846 * Build issues with Solaris and possible other architectures have been
1847 resolved.
1848 * Problems when building the `apache'-plugin without `libcurl' have
1849 been resolved.
1850 * A bug in the `ping' plugin has been fixed. Sorry folks.
1852 2006-04-02, Version 3.9.0
1853 * A plugin to monitor the Apache webserver has been added.
1854 <http://httpd.apache.org/>
1855 * A plugin to collect statistics about virtual servers using VServer.
1856 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1857 this plugin :)
1858 * A plugin for wireless LAN cards has been added. It monitors signal
1859 strength, link quality and noise ratio..
1860 * A plugin for Apple hardware sensors has been added.
1861 * An option to compile collectd with different `step' and `heartbeat'
1862 settings has been added. The size of RRAs is no longer static but
1863 calculated based on the settings for `step' and `width'.
1864 * The `ping' plugin can now be configured to use a certain TTL.
1865 * A plugin to monitor the hardware sensors of Apple computers has been
1866 added.
1867 * The plugins `cpu', `memory', `processes' and `traffic' have been
1868 ported to Mach/Darwin (Mac OS X).
1869 * The `log mode' has been contributed by Christophe Kalt. It writes
1870 the data into text files rather than RRD files.
1872 2006-04-09, Version 3.8.4
1873 * Applied patch by Vincent Stehlé which improves the disk-name
1874 resolution in the `hddtemp' plugin for Linux systems.
1876 2006-04-02, Version 3.8.3
1877 * Applied a patch by James Byers: The MySQL plugin was not working
1878 with MySQL 5.0.2 or later.
1880 2006-03-14, Version 3.8.2
1881 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1882 the GNU libc, because it points to `/etc/fstab' rather than
1883 `/etc/mtab'.
1885 2006-03-13, Version 3.8.1
1886 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1887 * Fixes in the debian `postinst' and `init.d' scripts.
1889 2006-03-09, Version 3.8.0
1890 * The `ping' plugin no longer uses `libping' but a self written
1891 library named `liboping'. With this library it's possible to ping
1892 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1894 2006-02-18, Version 3.7.2
1895 * A simple bug in the `battery' plugin has been fixed. It should now
1896 work with ACPI based batteries as well. Thanks to Sebastian for
1897 fixing this.
1898 * Fixing a bug that prevented collectd to be built without librrd.
1899 Thanks to Werner Heuser for reporting it.
1901 2006-02-04, Version 3.7.1
1902 * The new network code has been improved to build with older versions
1903 of glibc.
1904 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1905 to Tommie Gannert for this patch.
1907 2006-01-30, Version 3.7.0
1908 * The `battery' plugin has been added. It collects information about
1909 laptop batteries..
1910 * The MySQL plugin has been improved: It now writes two more RRD
1911 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1912 * The `cpufreq' plugin now reads another file since the file it did
1913 read so far causes much overhead in the kernel. Also, you need root
1914 to read the old file, but not to read the new one.
1915 * The `hddtemp' plugin can now be configured to connect to another
1916 address and/or port than localhost.
1917 * The `df' plugin now prefers `statvfs' over `statfs'.
1918 * The network code has been rewritten. collectd now supports unicast
1919 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1920 be set in the configfile.
1922 2006-01-24, Version 3.6.2
1923 * Due to a bug in the configfile handling collectd wouldn't start in
1924 client mode. This released fixes this.
1926 2006-01-20, Version 3.6.1
1927 * Due to a bug in `configure.in' all modules and the binary were
1928 linked against `libmysqlclient'. This issue is solved by this
1929 release.
1931 2006-01-17, Version 3.6.0
1932 * A config file has been added. This allows for loading only specific
1933 plugins.
1934 * A `df' plugin has been added.
1935 * A `mysql' plugin has been added.
1936 * The `ping' plugin doesn't entirely give up hope when a socket error
1937 occurred, but will back of and increase the intervals between tries.
1939 2006-01-21, Version 3.5.2
1940 * Fixed yet another bug in the signal handling.. Stupid typo..
1941 * Improved the ping plugin to not give up on socket errors (backport
1942 from 3.6.0).
1944 2005-12-18, Version 3.5.1
1945 * The PID-file is now deleted correctly when shutting down the daemon.
1946 * SIGINT and SIGTERM are now handled correctly.
1948 2005-12-16, Version 3.5.0 (Revision 326)
1949 * A bug in the `load' module under Solaris has been fixed.
1950 * The `users' module has been contributed by Sebastian Harl. It counts
1951 currently logged in users.
1952 * The CPU module now works under FreeBSD without the use of
1953 `libstatgrab', however SMP support is missing.
1954 * The default directories for the RRD files and the PID file now
1955 depend on the compile time setting of `localstatedir'.
1957 2005-11-15, Version 3.4.0 (Revision 236)
1958 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1959 from gentoo's bugzilla for writing the patch.
1960 * The build dependency for librrd has been removed. Binaries built
1961 without librrd are client-only and will multicast their value as
1962 with the `-c' argument.
1963 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1964 * The newly introduced `-f' switch prevents daemon initialization
1965 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1966 Barcellos for this patch.
1968 2005-11-04, Version 3.3.0 (Revision 216)
1969 * New modules have been added:
1970 - `serial', for monitoring traffic on the serial interfaces
1971 - `nfs', for graphing NFS procedure calls
1972 - `tape', traffic from/to tape devices
1973 * The memory.rrd now accepts more than 4Gig of memory.
1975 2005-10-26, Version 3.2.0 (Revision 200)
1976 * Support for graphing the processes has been added (thanks to Lyonel
1977 Vincent)
1978 * If reading from hddtemp fails collectd will increase the time
1979 between polls up to one day.
1980 * The init.d files have been improved.
1981 * Problems with the spec file have been fixed.
1983 2005-10-16, Version 3.1.0 (Revision 194)
1984 * Added the `setsid' syscall to the startup code.
1985 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1987 2005-09-30, Version 3.0.0 (Revision 184)
1988 * The ability to send/receive data to/from the network (think
1989 multicast) has been added.
1990 * Modules have been split up into shared libraries can be loaded at
1991 runtime. The biggest advantage is that the core program doesn't need
1992 to be linked against an external library.
1993 * A patch by George Kargiotakis has been applied: It fixes the sensors
1994 behaviour then more than one sensor is being queried.
1996 2005-09-16, Version 2.1.0 (Revision 172)
1997 * A module for swap statistics has been added.
1999 2005-09-09, Version 2.0.0 (Revision 135)
2000 * Filenames can no longer be configured at program startup. The only
2001 options as of this version are the directory and ping hosts.
2002 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2003 Soft-IRQ statistics are added to `System'.
2004 * Diskstats now collect read and write bytes, not sectors.
2005 * Ping statistics can now be collected for more than one host. There
2006 is no default any more: If no host is given no host will be pinged.
2007 * A self-written patch for libping has been applied so it builds
2008 cleanly.
2010 2005-09-01, Version 1.8.1 (Revision 123)
2011 * Much improved configure-script: libraries and features may now be
2012 disabled.
2013 * More detailed warnings/error messages when RRD update fails.
2015 2005-08-29, Version 1.8.0:
2016 * Support for collecting disk statistics under Solaris.
2018 2005-08-25, Version 1.7.0:
2019 * Support for libstatgrab[1] for load, memory usage and network
2020 traffic. CPU- and disk-usage are not (yet) supported, since
2021 libstatgrab returns insufficient information. I will contact the
2022 authors.
2023 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2024 aren't necessarily counted linear which is now handled correctly.
2025 [1]: http://www.i-scream.org/libstatgrab/
2027 2005-08-21, Version 1.6.0:
2028 * Basic support for Solaris: System load and cpu-usage can be
2029 collected under Solaris, too. Other stats will follow later.
2030 * Many fixes in the autoconf-script
2031 * Collection/Museum scripts have been added under contrib/museum
2032 * collectd may now be started in unprivileged mode, though ping
2033 statistics will not work.
2035 2005-07-17, Version 1.5.1:
2036 * Diskstats-RRDs now use major/minor for naming. Some systems have
2037 weird strings as disk-names..
2039 2005-07-17, Version 1.5:
2040 * A new module, diskstats, has been added. It collects information
2041 about the disks and partitions.
2043 2005-07-11, Version 1.4.2:
2044 * The meminfo module has been changed to work with more platforms
2045 and/or kernel versions.
2047 2005-07-10, Version 1.4.1: Correct traffic stats
2048 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2049 forgot to correct when I changed that module.
2051 2005-07-09, Version 1.4: More traffic stats
2052 * Traffic is now collected for all interfaces that can be found
2053 * Temperature-statistics are read from lm-sensors if available
2055 2005-07-08, Version 1.3: CPU stats
2056 * Collecting CPU statistics now
2058 2005-07-12, Version 1.2: Using syslog
2059 * collectd is now using the syslog facility to report errors, warnings
2060 and the like..
2061 * The default directory is now /var/db/collectd
2063 2005-07-10, Version 1.1: Minor changes
2064 * Nothing really useful to say ;)
2066 2005-07-09, Version 1.0: Initial Version
2067 * The following modules are provided:
2068 * Load average
2069 * Ping time
2070 * Traffic
2071 * Memory info
