696 J. Díaz for fixing these problems.
697 * collectd: Handling of the `Include' configuration option has been
698 fixed.

812 Bruno Prémont for finding this problem.
813 * bind plugin: Fix collection of the cached RR sets. The number of RR
814 sets currently in the cache was collected as a counter value, which
815 is nonsense. Thanks to Bruno Prémont for implementing this.
816 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
817 primarily BSDs, don't take it well and crash.
818 * oracle plugin: Portability to 64 bit systems has been improved.
819 * postgresql plugin: The default configuration has been improved.
820 * rrdtool plugin: Fix a possible race condition: If the network plugin

862 * curl plugin: This new plugin can be used to read web pages and parse
863 them using the same mechanism that's used in the tail plugin.
864 * dbi plugin: This new plugin allows you to connect to a variety of
865 relational databases and use SQL to gather custom statistics from
866 it. It is similar to the already existing PostgreSQL plugin but uses
867 libdbi to communicate with the database(s).
868 * interface plugin: Use the ignorelist framework when selecting /
869 ignoring interfaces. This allows one to use regular expressions to
870 select interfaces, too.

894 been added.
895 * processes plugin: Stacksize and virtual memory usage statistics have
896 been added. Portability fixes.
897 * rrdcached plugin: This new plugin uses the (still in development)
898 RRD accelerator daemon, rrdcached. This daemon works very similar to
899 the original rrdtool plugin of collectd, but adds some more nice
900 features.

932 * ipmi plugin: Fix an off-by-one error which could cause segmentation
933 faults. Thanks to Peter Holik for his patch.
934 * tcpconns plugin: An endianness problem has been fixed in the *BSD
935 code. Thanks to "thated" for reporting this.
937 2009-01-02, Version 4.5.2
938 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
939 file may be in both locations, especially when the database was
940 installed in a non-standard path. Thanks to Dusty Doris for
941 reporting this.
942 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
943 Solaris, in the configure script automatically.
944 * build system, tcpconns plugin: Check for `kvm_nlist' and
945 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
946 library with similar functions to the BSD variant, but doesn't
947 provide these necessary functions.
948 * collectd.conf(5): Various fixes and clarifications.
949 * collectd: Remove a GNUism (unnamed unions), thus improving
950 portability.
951 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
952 This solves portability problems, especially for Solaris.
953 * dns plugin: Fix a portability problem with NetBSD.
954 * filecount plugin: Fix an off-by-one error. This error may cause a
955 segmentation fault.
956 * network plugin: Fix the handling of `type' in the network protocol.
957 Due to a programming mistake, only 4 or 8 bytes would be copied to a
958 much larger buffer. This caused the `type' to be transferred much
959 more often than necessary. In some cases, e. g. the `cpu' and
960 `cpufreq' plugins being used at the same time, data may be corrupted
961 in those files. Thanks to Bruno Prémont for debugging and reporting
962 this issue.
963 * processes plugin: Fix a possible segmentation fault when specifying
964 invalid configuration options.
965 * unixsock plugin: Make sure the initialization function is run only
966 once. This resolves a file descriptor leak under systems which run
967 the initialization more than once, such as Solaris.
969 2008-10-16, Version 4.5.1
970 * build system: Change `--enable-<plugin>' to abort with an error if
971 dependencies are not met. Thanks to Bruno Prémont for the patch.
972 Also, the poisoning of various string functions has been restricted
973 to debug builds.
974 * collectd: Fix a memory leak in the global value cache. With every
975 *missing* value a couple of bytes would be leaked. Another memory
976 leak in the configuration handling code has been fixed. Thanks to
977 Niraj Tolia for reporting these issues.
978 * collectd: Fix an off-by-one error in the ignorelist functionality.
979 When using regular expressions, the last character would be missing,
980 possibly matching differently from what one would expect.
981 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
982 problem.
983 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
984 Linzberger for reporting the bug.
985 * iptables plugin: Fix an off-by-one error. If a string was just one
986 character too long, it was truncated instead of reporting an error.
987 * network plugin: Fix a memory leak in the configuration handling
988 code. Thanks to Niraj Tolia for reporting this issue.
989 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
990 * postgresql plugin: Don't reopen connection during reinitialization.
991 This fixes a bug under Solaris and potentially other platforms.
992 Missing calls to `PQclear' have been added, too. This fixes memory
993 leaks. Thanks to ``Admin'' for reporting these bugs.
994 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
995 library.
996 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
997 problems with some `libc's. Thanks to Matthias Lay for reporting the
998 bug.
1000 2008-09-04, Version 4.5.0
1001 * collectd: Added the ability to flush certain identifiers.
1002 * collectd: The concept of `notification meta data' has been
1003 introduced.
1004 * filecount plugin: The new filecount plugin counts the number of
1005 files in a directory and its subdirectories.
1006 * ipmi plugin: Sensor names have been changed to ensure unique names.
1007 Notifications upon added and removed sensors can now be generated.
1008 * notify_desktop plugin: This new plugin sends notifications to the
1009 X desktop using the structure defined in the `Desktop Notification
1010 Specification'.
1011 * notify_email plugin: This new plugin sends out notifications via
1012 email, using the `esmtp' library.
1013 * onewire plugin: The new experimental(!) onewire plugin reads values,
1014 such as temperatures, from sensors connected to the computer via the
1015 onewire bus.
1016 * perl plugin: Improved synchronized access to internal data structures
1017 and fixed a possible dead-lock.
1018 * perl plugin: Added the ability to flush certain identifiers and marked
1019 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1020 plugin_flush().
1021 * perl plugin: Added the ability to configure Perl plugins.
1022 * postgresql plugin: The new postgresql plugin collects statistics
1023 about or from a PostgreSQL database.
1024 * processes plugin: The `ProcessMatch' option has been added.
1025 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1026 IO load.
1027 * tcpconns plugin: This plugin has been ported to OpenBSD.
1028 * thermal plugin: The new thermal plugin collects system temperatures
1029 using Linux ACPI thermal zone data.
1031 2009-01-02, Version 4.4.5
1032 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1033 file may be in both locations, especially when the database was
1034 installed in a non-standard path. Thanks to Dusty Doris for
1035 reporting this.
1036 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1037 Solaris, in the configure script automatically.
1038 * collectd.conf(5): Various fixes and clarifications.
1039 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1040 portability problems, especially for Solaris.
1041 * dns plugin: Fix a portability problem with NetBSD.
1042 * network plugin: Fix the handling of `type' in the network protocol.
1043 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1044 much larger buffer. This caused the `type' to be transferred much
1045 more often than necessary. In some cases, e. g. the `cpu' and
1046 `cpufreq' plugins being used at the same time, data may be corrupted
1047 in those files. Thanks to Bruno Prémont for debugging and reporting
1048 this issue.
1049 * unixsock plugin: Make sure the initialization function is run only
1050 once. This resolves a file descriptor leak under systems which run
1051 the initialization more than once, such as Solaris.
1053 2008-10-16, Version 4.4.4
1054 * build system: Change `--enable-<plugin>' to abort with an error if
1055 dependencies are not met. Thanks to Bruno Prémont for the patch.
1056 Also, the poisoning of various string functions has been restricted
1057 to debug builds.
1058 * collectd: Fix a memory leak in the global value cache. With every
1059 *missing* value a couple of bytes would be leaked. Another memory
1060 leak in the configuration handling code has been fixed. Thanks to
1061 Niraj Tolia for reporting these issues.
1062 * collectd: Fix an off-by-one error in the ignorelist functionality.
1063 When using regular expressions, the last character would be missing,
1064 possibly matching differently from what one would expect.
1065 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1066 problem.
1067 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1068 Linzberger for reporting the bug.
1069 * network plugin: Fix a memory leak in the configuration handling
1070 code. Thanks to Niraj Tolia for reporting this issue.
1071 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1072 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1073 problems with some `libc's. Thanks to Matthias Lay for reporting the
1074 bug.
1076 2008-09-01, Version 4.4.3
1077 * collectd: Fix a memory leak in the threshold checking code.
1078 * memcached plugin: Fix a too short timeout and a related file
1079 descriptor leak.
1080 * memory plugin: A typo in the libstatgrab code has been fixed.
1081 * snmp plugin: Fix a possible memory leak.
1083 2008-07-15, Version 4.4.2
1084 * build system: Use pkg-config to detect the upsclient library.
1085 * collectd: Try even harder to determine the endianess of the
1086 architecture collectd is being built on.
1087 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1088 of disks.
1089 * dns plugin: Fix compilation errors with BIND versions 19991001
1090 through 19991005.
1091 * network plugin: Bugfix in the init routine: The init function
1092 cleared a buffer regardless of its contents. This could lead to lost
1093 values under Solaris.
1094 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1095 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1096 function.
1097 * wireless plugin: Work around incorrect noise and power values
1098 returned by some broken drivers.
1100 2008-06-03, Version 4.4.1
1101 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1102 to kyrone for reporting this.
1103 * collectd: Fixed min/max output in notifications generated by
1104 threshold checking.
1105 * collectd-nagios: Fix the protocol used to communicate with the
1106 daemon.
1107 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1108 initialization has errors. An issue with Perl 5.10 has been fixed.
1109 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1110 René Rebe and Siegmund Gorr for reporting this.
1112 2008-05-06, Version 4.4.0
1113 * collectd: Internal code cleanups.
1114 * collectd: Added support for a `Flush' command in the unixsock and
1115 exec plugins. This command can be used to force a plugin (or all) to
1116 flush its values to disk.
1117 * collectd: Thresholds can now be configured to apply to one data
1118 source only, making it possible to configure different thresholds
1119 for each data source.
1120 * apache, nginx plugins: Added the possibility to disable host and/or
1121 peer verification.
1122 * ascent plugin: The new ascent plugin reads and parses the statistics
1123 page of an Ascent server.
1124 * cpu plugin: Support for the statgrab library has been added.
1125 * disk plugin: The possibility to ignore certain disks or collect only
1126 specific disks has been added.
1127 * disk plugin: Support for the statgrab library has been added.
1128 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1129 sensor values via IPMI, the intelligent platform management
1130 interface.
1131 * iptables plugin: The iptc library that is used by the iptables
1132 plugin has been added to the distribution, because it is not
1133 provided by all distributions and removed from at least one.
1134 * powerdns plugin: The new powerdns plugin reads statistics from an
1135 authoritative or a recursing PowerDNS name server.
1136 * rrdtool plugin: The size of the files generated with the default
1137 configuration has been decreased.
1138 * tail plugin: The new tail plugin can be used to gather statistics by
1139 continuously reading from log files.
1140 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1141 TeamSpeak2 server and collects statistics about the number of users
1142 and number of channels.
1143 * users plugin: Support for the statgrab library has been added.
1144 * vmem plugin: The new vmem plugin collects very detailed statistics
1145 about the virtual memory subsystem of Linux.
1147 2008-08-30, Version 4.3.4
1148 * Build system: Improved detection of and linking with the statgrab
1149 library.
1150 * collectd: Portability fixes, especially to determine endianess more
1151 reliable.
1152 * Various plugins: Fix format strings.
1153 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1154 again has been applied.
1155 * memcached plugin: Fix a too short timeout and a related file
1156 descriptor leak.
1157 * memory plugin: A typo in the libstatgrab code has been fixed.
1158 * network plugin: A fix in the initialization function solves problems
1159 under Solaris.
1160 * nginx plugin: A thread-unsafe function has been replaced.
1161 * vserver plugin: A thread-unsafe function has been replaced.

1163 added.
1165 2008-04-22, Version 4.3.3
1166 * build system: Improved detection of several libraries, especially if
1167 they are in non-standard paths.
1168 * build system: Portability fixes: Automatically define "_REENTRANT"
1169 if the libc expects it.
1170 * collectd: Error and warning messages have been improved.
1171 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1172 using them.
1173 * apache plugin: Allocate new memory when reading a webpage instead of
1174 using a buffer of static size.
1175 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1176 the program.
1177 * hddtemp plugin: Error and warning messages have been improved.
1178 * sensors plugin: Fix sensor collection for some chip types.
1180 2008-03-29, Version 4.3.2
1181 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1182 `Persist' threshold options.
1183 * collectd: Fix handling of missing values in the global value cache.
1184 * collectd: Improved error messages when parsing the configuration.
1185 * sensors plugin: Fix temperature collection with libsensors4.
1186 * unixsock plugin: Fix mixed input and output operation on streams.
1187 * wireless plugin: Fix reading noise value.
1189 2008-03-05, Version 4.3.1
1190 * exec plugin: Set supplementary group IDs.
1191 * network plugin:
1192 + Use `memcpy' when constructing/parsing a package to avoid
1193 alignment problems on weird architectures, such as Sparc.
1194 + Translate doubles to/from the x86 byte representation to ensure
1195 cross-platform compatibility.
1196 * ping plugin: Correct the handling of the `TTL' setting.
1197 * swap plugin: Reapply a patch for Solaris.
1198 * tcpconns plugin: Portability improvements.
1200 2008-02-18, Version 4.3.0
1201 * collectd: Notifications have been added to the daemon. Notifications
1202 are status messages that may be associated with a data instance.
1203 * collectd: Threshold checking has been added to the daemon. This
1204 means that you can configure threshold values for each data
1205 instance. If this threshold is exceeded a notification will be
1206 created.
1207 * collectd: The new `FQDNLookup' option tells the daemon to use the
1208 full qualified domain name as the hostname, not just the host part
1209 es returned by `gethostname(2)'.
1210 * collectd: Support for more than one `TypesDB' file has been added.
1211 This is useful when one such file is included in a package but one
1212 wants to add custom type definitions.
1213 * collectd: The `Include' config option has been expanded to handle
1214 entire directories and shell wildcards.
1215 * collectdmon: The new `collectdmon' binary detects when collectd
1216 terminates and automatically restarts it again.
1217 * csv plugin: The CSV plugin is now able to store counter values as a
1218 rate, using the `StoreRates' configuration option.
1219 * exec plugin: Handling of notifications has been added and the
1220 ability to pass arguments to the executed programs has been added.
1221 * hddtemp plugin: The new `TranslateDevicename' option lets you
1222 disable the translation from device names to major-minor-numbers.
1223 * logfile plugin: Handling of notifications has been added.
1224 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1225 domain name lookups in this plugin.
1226 * perl plugin: Many internal changes added support for handling multiple
1227 threads making the plugin reasonably usable inside collectd. The API has
1228 been extended to support notifications and export global variables to
1229 Perl plugins; callbacks now have to be identified by name rather than a
1230 pointer to a subroutine. The plugin is no longer experimental.
1231 * uuid plugin: The new UUID plugin sets the hostname to an unique
1232 identifier for this host. This is meant for setups where each client
1233 may migrate to another physical host, possibly going through one or
1234 more name changes in the process. Thanks to Richard Jones from
1235 Red Hat's Emerging Technology group for this plugin.
1236 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1237 CPU, disk and network statistics about guest systems on the same
1238 physical server. Thanks to Richard Jones from Red Hat's Emerging
1239 Technology group for this plugin.
1241 2008-04-22, Version 4.2.7
1242 * build system: Improved detection of several libraries, especially if
1243 they are in non-standard paths.
1244 * build system: Portability fixes: Automatically define "_REENTRANT"
1245 if the libc expects it.
1246 * collectd: Error and warning messages have been improved.
1247 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1248 using them.
1249 * apache plugin: Allocate new memory when reading a webpage instead of
1250 using a buffer of static size.
1251 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1252 the program.
1253 * hddtemp plugin: Error and warning messages have been improved.
1254 * sensors plugin: Fix sensor collection for some chip types.
1256 2008-03-29, Version 4.2.6
1257 * collectd: Improved error messages when parsing the configuration.
1258 * sensors plugin: Fix temperature collection with libsensors4.
1259 * unixsock plugin: Fix mixed input and output operation on streams.
1260 * wireless plugin: Fix reading noise value.
1262 2008-03-04, Version 4.2.5
1263 * apache plugin: Improved initialization and error messages.
1264 * exec plugin: Set supplementary group IDs.
1265 * network plugin:
1266 + Create separate threads for reading from the socket and parsing
1267 and dispatching incoming packets. Versions prior to this may have
1268 problems in high-load situations, where the socket receive buffers
1269 overflows, resulting in gaps in the data.
1270 + Use `memcpy' when constructing/parsing a package to avoid
1271 alignment problems on weird architectures, such as Sparc.
1272 + Translate doubles to/from the x86 byte representation to ensure
1273 cross-platform compatibility.
1274 * ping plugin: Correct the handling of the `TTL' setting.
1275 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1276 * swap plugin: Reapply a patch for Solaris.
1277 * tcpconns plugin: Portability improvements.
1279 2008-01-21, Version 4.2.4
1280 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1281 the permission on the socket as documented in the manpage. Thanks to
1282 Evgeny Chukreev for fixing this issue.
1283 * collectd: The documentation has been improved.
1285 2007-12-28, Version 4.2.3
1286 * sensors plugin: Updated the plugin to build and work with version 3
1287 of the libsensors library.
1289 2007-12-15, Version 4.2.2
1290 * nginx plugin: Incorrect comparison of strings lead to a segfault
1291 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1292 this.
1293 * logfile plugin: The config option `Timestamp' was handled
1294 incorrectly and basically always active. Thanks to Luke Heberling
1295 for fixing this.
1297 2007-11-08, Version 4.2.1
1298 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1299 enabled on the host.
1300 * snmp plugin: Fix a memory leak.
1302 2007-10-27, Version 4.2.0
1303 * collectd: The new config option `Include' lets you include other
1304 configfiles and thus split up your config into smaller parts. This
1305 may be especially interesting for the snmp plugin to keep the data
1306 definitions separate from the host definitions.
1307 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1308 (number of connections, octets and packets for each service and
1309 destination). Thanks to Sebastian Harl for this plugin.
1310 * memcached plugin: The new `memcached' plugin connects to a memcached
1311 daemon process and collects statistics of this distributed caching
1312 system. Thanks to Antony Dovgal for contributing this plugin.
1313 * nginx plugin: The new `nginx' plugin reads the status page of an
1314 nginx daemon and saves the handled connections and requests.
1315 * perl plugin: Many changes, including the added `EnableDebugger'
1316 config option which lets you debug your Perl plugins more easily.
1317 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1318 be more thread-safe otherwise by locking calls to the library.
1319 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1320 correct the values returned by SNMP-agents. If a <data> block is
1321 defined as `table' the instance is now optional. The sequence number
1322 is used as the type-instance in this case. The new `InstancePrefix'
1323 option allows to add arbitrary prefixes to the type-instance.
1324 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1325 certain TCP connections and what state they're in. This can be used
1326 to see how many connections your FTP server has to handle or how
1327 many outgoing connections your mailserver has open.
1329 2008-01-11, Version 4.1.6
1330 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1331 the permission on the socket as documented in the manpage. Thanks to
1332 Evgeny Chukreev for fixing this issue.
1333 * collectd: The documentation has been improved.
1335 2007-12-27, Version 4.1.5
1336 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1337 memory situations.
1338 * sensors plugin: Updated the plugin to build and work with version 3
1339 of the libsensors library.
1341 2007-11-08, Version 4.1.4
1342 * Build system: Improve detection of the rrd library, especially if
1343 it's in a non-standard location.
1344 * Build system: A bug when parsing the argument for
1345 `--with-libnetsnmp' has been fixed.
1346 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1347 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1348 a deadlock or delay when shutting down the daemon.
1349 * snmp plugin: Fix a memory leak.
1351 2007-10-24, Version 4.1.3
1352 * collectd: A build issue under Solaris has been resolved by renaming
1353 data types.
1354 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1355 be more thread-safe otherwise by locking calls to the library.
1357 2007-09-28, Version 4.1.2
1358 * apcups plugin: Fix reporting of the `load percent' data.
1359 * wireless plugin: Correct the handling of cards returning signal and
1360 noise quality as percentage.
1361 * perl plugin: Fix a possible buffer overflow in get_module_name().
1362 * build system: Further improve the detection of libraries.
1363 * netlink plugin: Build issues under some older versions of the Linux
1364 includes (i. e. Debian Sarge) have been fixed.
1365 * snmp plugin: Fix a potential segfault when a host times out. Add
1366 support for the `timeticks' type.
1368 2007-09-12, Version 4.1.1
1369 * Build system: The detection of `libnetlink' has been improved.
1370 * collectd: The documentation has been fixed in numerous places.
1371 * exec plugin: Setting the group under which to run a program has been
1372 fixed.
1373 * collectd: The `sstrerror' function was improved to work correctly
1374 with the broken GNU version of `strerror_r'.
1375 * collectd: Write an error message to STDERR when loading of a plugin
1376 fails.
1377 * apcups plugin: Fix the `types' used to submit the values: They still
1378 has an `apcups_' prefix which doesn't work anymore.
1379 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1380 whatever the client thinks is `now'..
1382 2007-09-01, Version 4.1.0
1383 * Build system: The build system has been changed to automatically
1384 disable all plugins, which are missing dependencies. The dependency
1385 checking has been removed from the plugins themselves to remove
1386 redundancy.
1387 * Flexible interval: The interval of collected data is now sent along
1388 with the data itself over the network, so that the interval-settings
1389 of server and clients no longer needs to match.
1390 * netlink plugin: The new `netlink' plugin connects to the Linux
1391 kernel using a netlink socket and uses it to query information about
1392 interfaces, qdiscs and classes.
1393 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1394 to not block data collection.
1395 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1396 network devices, such as switches, routers, thermometers, rack
1397 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1398 plugin.
1399 * unixsock plugin: Added the `LISTVAL' command.
1400 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1401 of music played with xmms.
1403 2007-09-28, Version 4.0.9
1404 * apcups plugin: Fix reporting of the `load percent' data.
1405 * wireless plugin: Correct the handling of cards returning signal and
1406 noise quality as percentage.
1407 * perl plugin: Fix a possible buffer overflow in get_module_name().
1409 2007-09-12, Version 4.0.8
1410 * collectd: The `sstrerror' function was improved to work correctly
1411 with the broken GNU version of `strerror_r'.
1412 * collectd: Write an error message to STDERR when loading of a plugin
1413 fails.
1414 * apcups plugin: Fix the `types' used to submit the values: They still
1415 has an `apcups_' prefix which doesn't work anymore.
1416 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1417 whatever the client thinks is `now'..
1419 2007-08-26, Version 4.0.7
1420 * documentation: Some typos have been fixed and some information has
1421 been improved.
1422 * build system: Many fixes for detecting libraries in unusual places,
1423 such as on RedHat systems. The affected libraries are `libcurl',
1424 `libmysql', and `libupsclient'.
1425 * network plugin: Allow the `Port' option to be specified as a number
1426 (i. e. without quotes).
1427 * nut plugin: A fix allows linking the nut plugin against
1428 libupsclient, version >= 2.2.0.
1429 * processes plugin: Fix a potential segmentation fault.
1431 2007-07-30, Version 4.0.6
1432 * sensors plugin: Fix the ignorelist functionality: Only the `type
1433 instance' was used to match against the list, but the documentation
1434 told otherwise. This release fixes the code, so it complies with the
1435 documentation.
1436 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1437 configuration messages will end up in the logging facility.
1438 * conrtib/fedora: The contributed specfile for Fedora has been
1439 updated.
1441 2007-07-05, Version 4.0.5
1442 * Portability: More fixes for OpenBSD have been included.
1444 2007-06-24, Version 4.0.4
1445 * cpu plugin: Fixed the Solaris code.
1446 * dns plugin: Fixed a build issue for OpenBSD.
1447 * interface plugin: Fixed the Solaris code.
1448 * load plugin: Fixed the alternative `/proc' Linux code.
1449 * memory plugin: Fixed the Solaris code.
1450 * oconfig: Don't require `-lfl' anymore.
1452 2007-06-19, Version 4.0.3
1453 * cpu plugin: Fix the Darwin / Mac OS X code.
1454 * ping plugin: Use the return value of `getpid', not its address.
1455 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1456 initialized correctly.
1457 * configure: Added `--with-nan-emulation' to aid cross compilation.
1459 2007-06-12, Version 4.0.2
1460 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1461 they're given in numerically form.
1463 2007-06-07, Version 4.0.1
1464 * iptables plugin: A bug in the configuration routine has been fixed.
1465 Setting a comment in the configfile will no longer cause a
1466 segmentation fault.
1468 2007-06-03, Version 4.0.0
1469 * collectd: The plugin-infrastructure has been changed to allow for
1470 more types of plugins, namely `write' and `log' plugins.
1471 * collectd: The read-function has been changed to read many plugins in
1472 parallel, using threads. Thus, plugins generally need to use
1473 thread-safe functions from now on.
1474 * collectd: The '-t' command line options allows to perform syntax tests
1475 of the configuration file and exit immediately.
1476 * csv plugin: The new `csv' plugin handles output to `comma separated
1477 values'-files.
1478 * rrdtool plugin: The new `rrdtool' plugin handles output to
1479 RRD-files. Data can be cached to combine multiple updates into one
1480 write to increase IO-performance.
1481 * network plugin: The new `network' plugin handles IO via the network.
1482 It implements a different, much more extensible protocol which can
1483 combine many values in one packet, decreasing the number of UDP-
1484 packets being sent. It can read from and send to the network and
1485 with the appropriate configuration even forward packets to other
1486 networks.
1487 * unixsock plugin: The new `unixsock' plugin provides an interface to
1488 communicate with the daemon while it is running. Right now the
1489 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1490 come.
1491 * perl plugin: The new `perl' plugin allows you to write extensions
1492 for collectd in the scripting-language Perl.
1493 * logfile plugin: The new `logfile' plugin writes logmessages to files
1494 or STDOUT or STDERR.
1495 * syslog plugin: The new `syslog' plugin sends logmessages to the
1496 system's syslog daemon.
1497 * entropy plugin: The new `entropy' plugin collects the amount of
1498 entropy currently being available to the system.
1499 * exec plugin: The new `exec' plugin forks child processes and reads
1500 back values provided by the forked processes.
1501 * iptables plugin: The new `iptables' plugin reads counters from
1502 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1503 plugin.
1504 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1505 to Peter Holik for contributing this plugin.
1506 * nut plugin: The new `nut' plugin connects the upsd of the `network
1507 ups tools' and reads information about the connected UPS.
1508 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1509 connections) field was added by Florent Monbillard.
1510 * collectd-nagios: The new `collectd-nagios' binary queries values
1511 from collectd, parses them and exits according to Nagios-standards.
1512 * manpages: The manpages have been improved a lot.
1514 2007-09-28, Version 3.11.7
1515 * wireless plugin: Correct the handling of cards returning signal and
1516 noise quality as percentage.
1518 2007-08-31, Version 3.11.6
1519 * processes plugin: Fix a potential segmentation fault.
1521 2007-05-29, Version 3.11.5
1522 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1523 * ntpd plugin: Fix a potential buffer overflow.
1524 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1525 were accounted as `zombies'.
1527 2007-04-10, Version 3.11.4
1528 * dns plugin: Change the order of includes to make the plugin compile
1529 under FreeBSD.
1531 2007-03-30, Version 3.11.3
1532 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1533 of the unused `COLLECT_KSTAT'.
1535 2007-02-11, Version 3.11.2
1536 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1537 NULL-pointer may have been passed to `printf' which causes a
1538 segfault with some libcs.
1540 2007-02-10, Version 3.11.1
1541 * df plugin: Some wrong defines have been fixed so the plugin works
1542 under Solaris again.
1543 * dns plugin: The usage of a struct has been fixed to work with
1544 non-GNU libcs.
1545 * processes plugin: Some missing defines have been added so the plugin
1546 compiles cleanly under FreeBSD and presumably other UNIXes.
1548 2006-12-22, Version 3.11.0
1549 * collectd: The new command line option `-P' makes it easier for
1550 distributors to change the location of PID-files.
1551 * collectd: The daemon shuts down faster now which makes it easier to
1552 write init.d-scripts for it.
1553 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1554 caused problems every now and then.
1555 * df plugin: New config options allow to ignore certain mountpoints,
1556 filesystem types or devices.
1557 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1558 and interprets it. It collects traffic as well as qtype, opcode and
1559 rcode counts.
1560 * email plugin: Sebastian Harl has contributed this plugin which
1561 counts received mails in categories (e. g. ham, spam, virus), spam
1562 score (as given by SpamAssassin) and check types.
1563 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1564 uses `mbmon' to gather information from sensors on the motherboard.
1565 * processes plugin: Collect detailed statistics for configured
1566 processes, that's process and thread count, CPU usage, resident
1567 segment size and pagefaults.
1568 * multimeter plugin: Peter Holik contributed a new plugin which
1569 queries multimeters.
1570 * sensors plugin: Lubos Stanek has put much effort into improving this
1571 plugin, including `extended naming', collection of voltage values
1572 and the possibility to ignore certain values.
1574 2006-12-21, Version 3.10.4
1575 * Max Kellermann has identified a bug in the server routine: When
1576 opening a socket fails the daemon will (re)try opening the socket in
1577 an endless loop, ultimately leading to a `EMFILE' error.
1579 2006-11-04, Version 3.10.3
1580 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1581 ntpd's reply was sent in more than one packet, the buffer size was
1582 calculated incorrectly, resulting in the reading of uninitialized or
1583 freed memory.
1585 2006-11-01, Version 3.10.2
1586 * The sample config file has been improved.
1587 * Errors in the manpages have been corrected.
1588 * The ping-plugin now adds hosts during initialization, not during
1589 startup. This speeds up startup when no network connectivity is
1590 available. Also, the hosts are being added later when the network is
1591 available.
1592 * Improved BSD-support for the df-plugin.
1593 * Fixed syntax errors in the swap-plugin for Mac OS X.
1594 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1595 plugin.
1596 * Don't disable the mysql-plugin if connecting to the database fails
1597 during initialization. Instead, try again in increasing intervals.
1599 2006-07-19, Version 3.10.1
1600 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1601 the apcups cannot be reached, unconnected sockets will pile up and
1602 eventually lead to `Too many open files' errors.
1604 2006-07-09, Version 3.10.0
1605 * The `disk' plugin has been ported to Darwin.
1606 * The `battery' plugin should work on many Apple computers now.
1607 * The `traffic' plugin can now ignore certain interfaces. Also,
1608 statistics for sent/received packets and errors have been added.
1609 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1610 to Anthony Gialluca for contributing this plugin and providing me
1611 with a test environment :)
1612 * A plugin for monitoring an NTP instance and the local clock drift
1613 has been added.
1615 2006-06-25, Version 3.9.4
1616 * The Solaris code in the `swap' plugin has been changed to reflect
1617 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1618 working this out.
1619 * The debugging system has been fixed to work with the Sun libc.
1620 * When built without librrd the variable `operating_mode' could be
1621 uninitialized. Thanks to David Elliot for reporting the bug.
1623 2006-06-01, Version 3.9.3
1624 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1625 operating systems also profit from the changes, but I wasn't able to
1626 check that.
1627 * Changed the build system to find the netinet-includes under FreeBSD
1628 and therefore successfully build the `liboping' library there.
1630 2006-05-09, Version 3.9.2
1631 * Applied a patch to the `liboping' library. Due to a bug in the
1632 sequence checking the `ping' plugin stopped working after
1633 approximately 7.6 days.
1635 2006-05-09, Version 3.8.5
1636 * Applied a patch to the `liboping' library. Due to a bug in the
1637 sequence checking the `ping' plugin stopped working after
1638 approximately 7.6 days.
1640 2006-04-21, Version 3.9.1
1641 * Build issues with Solaris and possible other architectures have been
1642 resolved.
1643 * Problems when building the `apache'-plugin without `libcurl' have
1644 been resolved.
1645 * A bug in the `ping' plugin has been fixed. Sorry folks.
1647 2006-04-02, Version 3.9.0
1648 * A plugin to monitor the Apache webserver has been added.
1649 <http://httpd.apache.org/>
1650 * A plugin to collect statistics about virtual servers using VServer.
1651 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1652 this plugin :)
1653 * A plugin for wireless LAN cards has been added. It monitors signal
1654 strength, link quality and noise ratio..
1655 * A plugin for Apple hardware sensors has been added.
1656 * An option to compile collectd with different `step' and `heartbeat'
1657 settings has been added. The size of RRAs is no longer static but
1658 calculated based on the settings for `step' and `width'.
1659 * The `ping' plugin can now be configured to use a certain TTL.
1660 * A plugin to monitor the hardware sensors of Apple computers has been
1661 added.
1662 * The plugins `cpu', `memory', `processes' and `traffic' have been
1663 ported to Mach/Darwin (Mac OS X).
1664 * The `log mode' has been contributed by Christophe Kalt. It writes
1665 the data into text files rather than RRD files.
1667 2006-04-09, Version 3.8.4
1668 * Applied patch by Vincent Stehlé which improves the disk-name
1669 resolution in the `hddtemp' plugin for Linux systems.
1671 2006-04-02, Version 3.8.3
1672 * Applied a patch by James Byers: The MySQL plugin was not working
1673 with MySQL 5.0.2 or later.
1675 2006-03-14, Version 3.8.2
1676 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1677 the GNU libc, because it points to `/etc/fstab' rather than
1678 `/etc/mtab'.
1680 2006-03-13, Version 3.8.1
1681 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1682 * Fixes in the debian `postinst' and `init.d' scripts.
1684 2006-03-09, Version 3.8.0
1685 * The `ping' plugin no longer uses `libping' but a self written
1686 library named `liboping'. With this library it's possible to ping
1687 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1689 2006-02-18, Version 3.7.2
1690 * A simple bug in the `battery' plugin has been fixed. It should now
1691 work with ACPI based batteries as well. Thanks to Sebastian for
1692 fixing this.
1693 * Fixing a bug that prevented collectd to be built without librrd.
1694 Thanks to Werner Heuser for reporting it.
1696 2006-02-04, Version 3.7.1
1697 * The new network code has been improved to build with older versions
1698 of glibc.
1699 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1700 to Tommie Gannert for this patch.
1702 2006-01-30, Version 3.7.0
1703 * The `battery' plugin has been added. It collects information about
1704 laptop batteries..
1705 * The MySQL plugin has been improved: It now writes two more RRD
1706 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1707 * The `cpufreq' plugin now reads another file since the file it did
1708 read so far causes much overhead in the kernel. Also, you need root
1709 to read the old file, but not to read the new one.
1710 * The `hddtemp' plugin can now be configured to connect to another
1711 address and/or port than localhost.
1712 * The `df' plugin now prefers `statvfs' over `statfs'.
1713 * The network code has been rewritten. collectd now supports unicast
1714 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1715 be set in the configfile.
1717 2006-01-24, Version 3.6.2
1718 * Due to a bug in the configfile handling collectd wouldn't start in
1719 client mode. This released fixes this.
1721 2006-01-20, Version 3.6.1
1722 * Due to a bug in `configure.in' all modules and the binary were
1723 linked against `libmysqlclient'. This issue is solved by this
1724 release.
1726 2006-01-17, Version 3.6.0
1727 * A config file has been added. This allows for loading only specific
1728 plugins.
1729 * A `df' plugin has been added.
1730 * A `mysql' plugin has been added.
1731 * The `ping' plugin doesn't entirely give up hope when a socket error
1732 occurred, but will back of and increase the intervals between tries.
1734 2006-01-21, Version 3.5.2
1735 * Fixed yet another bug in the signal handling.. Stupid typo..
1736 * Improved the ping plugin to not give up on socket errors (backport
1737 from 3.6.0).
1739 2005-12-18, Version 3.5.1
1740 * The PID-file is now deleted correctly when shutting down the daemon.
1741 * SIGINT and SIGTERM are now handled correctly.
1743 2005-12-16, Version 3.5.0 (Revision 326)
1744 * A bug in the `load' module under Solaris has been fixed.
1745 * The `users' module has been contributed by Sebastian Harl. It counts
1746 currently logged in users.
1747 * The CPU module now works under FreeBSD without the use of
1748 `libstatgrab', however SMP support is missing.
1749 * The default directories for the RRD files and the PID file now
1750 depend on the compile time setting of `localstatedir'.
1752 2005-11-15, Version 3.4.0 (Revision 236)
1753 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1754 from gentoo's bugzilla for writing the patch.
1755 * The build dependency for librrd has been removed. Binaries built
1756 without librrd are client-only and will multicast their value as
1757 with the `-c' argument.
1758 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1759 * The newly introduced `-f' switch prevents daemon initialization
1760 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1761 Barcellos for this patch.
1763 2005-11-04, Version 3.3.0 (Revision 216)
1764 * New modules have been added:
1765 - `serial', for monitoring traffic on the serial interfaces
1766 - `nfs', for graphing NFS procedure calls
1767 - `tape', traffic from/to tape devices
1768 * The memory.rrd now accepts more than 4Gig of memory.
1770 2005-10-26, Version 3.2.0 (Revision 200)
1771 * Support for graphing the processes has been added (thanks to Lyonel
1772 Vincent)
1773 * If reading from hddtemp fails collectd will increase the time
1774 between polls up to one day.
1775 * The init.d files have been improved.
1776 * Problems with the spec file have been fixed.
1778 2005-10-16, Version 3.1.0 (Revision 194)
1779 * Added the `setsid' syscall to the startup code.
1780 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1782 2005-09-30, Version 3.0.0 (Revision 184)
1783 * The ability to send/receive data to/from the network (think
1784 multicast) has been added.
1785 * Modules have been split up into shared libraries can be loaded at
1786 runtime. The biggest advantage is that the core program doesn't need
1787 to be linked against an external library.
1788 * A patch by George Kargiotakis has been applied: It fixes the sensors
1789 behaviour then more than one sensor is being queried.
1791 2005-09-16, Version 2.1.0 (Revision 172)
1792 * A module for swap statistics has been added.
1794 2005-09-09, Version 2.0.0 (Revision 135)
1795 * Filenames can no longer be configured at program startup. The only
1796 options as of this version are the directory and ping hosts.
1797 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1798 Soft-IRQ statistics are added to `System'.
1799 * Diskstats now collect read and write bytes, not sectors.
1800 * Ping statistics can now be collected for more than one host. There
1801 is no default any more: If no host is given no host will be pinged.
1802 * A self-written patch for libping has been applied so it builds
1803 cleanly.
1805 2005-09-01, Version 1.8.1 (Revision 123)
1806 * Much improved configure-script: libraries and features may now be
1807 disabled.
1808 * More detailed warnings/error messages when RRD update fails.
1810 2005-08-29, Version 1.8.0:
1811 * Support for collecting disk statistics under Solaris.
1813 2005-08-25, Version 1.7.0:
1814 * Support for libstatgrab[1] for load, memory usage and network
1815 traffic. CPU- and disk-usage are not (yet) supported, since
1816 libstatgrab returns insufficient information. I will contact the
1817 authors.
1818 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1819 aren't necessarily counted linear which is now handled correctly.
1820 [1]: http://www.i-scream.org/libstatgrab/
1822 2005-08-21, Version 1.6.0:
1823 * Basic support for Solaris: System load and cpu-usage can be
1824 collected under Solaris, too. Other stats will follow later.
1825 * Many fixes in the autoconf-script
1826 * Collection/Museum scripts have been added under contrib/museum
1827 * collectd may now be started in unprivileged mode, though ping
1828 statistics will not work.
1830 2005-07-17, Version 1.5.1:
1831 * Diskstats-RRDs now use major/minor for naming. Some systems have
1832 weird strings as disk-names..
1834 2005-07-17, Version 1.5:
1835 * A new module, diskstats, has been added. It collects information
1836 about the disks and partitions.
1838 2005-07-11, Version 1.4.2:
1839 * The meminfo module has been changed to work with more platforms
1840 and/or kernel versions.
1842 2005-07-10, Version 1.4.1: Correct traffic stats
1843 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1844 forgot to correct when I changed that module.
1846 2005-07-09, Version 1.4: More traffic stats
1847 * Traffic is now collected for all interfaces that can be found
