626 name which prevented this match to be used as documented. Thanks to
627 Bruno Prémont for finding this problem.
628 * bind plugin: Fix collection of the cached RR sets. The number of RR
629 sets currently in the cache was collected as a counter value, which
630 is nonsense. Thanks to Bruno Prémont for implementing this.
631 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
632 primarily BSDs, don't take it well and crash.
633 * oracle plugin: Portability to 64 bit systems has been improved.
634 * postgresql plugin: The default configuration has been improved.
635 * rrdtool plugin: Fix a possible race condition: If the network plugin

678 them using the same mechanism that's used in the tail plugin.
679 * dbi plugin: This new plugin allows you to connect to a variety of
680 relational databases and use SQL to gather custom statistics from
681 it. It is similar to the already existing PostgreSQL plugin but uses
682 libdbi to communicate with the database(s).
683 * interface plugin: Use the ignorelist framework when selecting /
684 ignoring interfaces. This allows one to use regular expressions to
685 select interfaces, too.

711 been added. Portability fixes.
712 * rrdcached plugin: This new plugin uses the (still in development)
713 RRD accelerator daemon, rrdcached. This daemon works very similar to
714 the original rrdtool plugin of collectd, but adds some more nice

758 Solaris, in the configure script automatically.
759 * build system, tcpconns plugin: Check for `kvm_nlist' and
760 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM

771 * network plugin: Fix the handling of `type' in the network protocol.
772 Due to a programming mistake, only 4 or 8 bytes would be copied to a
773 much larger buffer. This caused the `type' to be transferred much
774 more often than necessary. In some cases, e. g. the `cpu' and
775 `cpufreq' plugins being used at the same time, data may be corrupted
776 in those files. Thanks to Bruno Prémont for debugging and reporting
778 * processes plugin: Fix a possible segmentation fault when specifying
779 invalid configuration options.
780 * unixsock plugin: Make sure the initialization function is run only

784 2008-10-16, Version 4.5.1
785 * build system: Change `--enable-<plugin>' to abort with an error if
786 dependencies are not met. Thanks to Bruno Prémont for the patch.
787 Also, the poisoning of various string functions has been restricted

791 leak in the configuration handling code has been fixed. Thanks to
792 Niraj Tolia for reporting these issues.
793 * collectd: Fix an off-by-one error in the ignorelist functionality.
794 When using regular expressions, the last character would be missing,
795 possibly matching differently from what one would expect.

798 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
799 Linzberger for reporting the bug.
800 * iptables plugin: Fix an off-by-one error. If a string was just one
801 character too long, it was truncated instead of reporting an error.
802 * network plugin: Fix a memory leak in the configuration handling
803 code. Thanks to Niraj Tolia for reporting this issue.
804 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

992 * hddtemp plugin: Error and warning messages have been improved.
993 * sensors plugin: Fix sensor collection for some chip types.
995 2008-03-29, Version 4.3.2
996 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
997 `Persist' threshold options.
998 * collectd: Fix handling of missing values in the global value cache.
999 * collectd: Improved error messages when parsing the configuration.
1000 * sensors plugin: Fix temperature collection with libsensors4.
1001 * unixsock plugin: Fix mixed input and output operation on streams.
1002 * wireless plugin: Fix reading noise value.
1004 2008-03-05, Version 4.3.1
1005 * exec plugin: Set supplementary group IDs.
1007 + Use `memcpy' when constructing/parsing a package to avoid
1008 alignment problems on weird architectures, such as Sparc.
1009 + Translate doubles to/from the x86 byte representation to ensure
1010 cross-platform compatibility.
1011 * ping plugin: Correct the handling of the `TTL' setting.
1012 * swap plugin: Reapply a patch for Solaris.
1013 * tcpconns plugin: Portability improvements.
1015 2008-02-18, Version 4.3.0
1016 * collectd: Notifications have been added to the daemon. Notifications
1017 are status messages that may be associated with a data instance.
1018 * collectd: Threshold checking has been added to the daemon. This
1019 means that you can configure threshold values for each data
1020 instance. If this threshold is exceeded a notification will be
1022 * collectd: The new `FQDNLookup' option tells the daemon to use the
1023 full qualified domain name as the hostname, not just the host part
1024 es returned by `gethostname(2)'.
1025 * collectd: Support for more than one `TypesDB' file has been added.
1026 This is useful when one such file is included in a package but one
1027 wants to add custom type definitions.
1028 * collectd: The `Include' config option has been expanded to handle
1029 entire directories and shell wildcards.
1030 * collectdmon: The new `collectdmon' binary detects when collectd
1031 terminates and automatically restarts it again.
1032 * csv plugin: The CSV plugin is now able to store counter values as a
1033 rate, using the `StoreRates' configuration option.
1034 * exec plugin: Handling of notifications has been added and the
1035 ability to pass arguments to the executed programs has been added.
1036 * hddtemp plugin: The new `TranslateDevicename' option lets you
1037 disable the translation from device names to major-minor-numbers.
1038 * logfile plugin: Handling of notifications has been added.
1039 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1040 domain name lookups in this plugin.
1041 * perl plugin: Many internal changes added support for handling multiple
1042 threads making the plugin reasonably usable inside collectd. The API has
1043 been extended to support notifications and export global variables to
1044 Perl plugins; callbacks now have to be identified by name rather than a
1045 pointer to a subroutine. The plugin is no longer experimental.
1046 * uuid plugin: The new UUID plugin sets the hostname to an unique
1047 identifier for this host. This is meant for setups where each client
1048 may migrate to another physical host, possibly going through one or
1049 more name changes in the process. Thanks to Richard Jones from
1050 Red Hat's Emerging Technology group for this plugin.
1051 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1052 CPU, disk and network statistics about guest systems on the same
1053 physical server. Thanks to Richard Jones from Red Hat's Emerging
1054 Technology group for this plugin.
1056 2008-04-22, Version 4.2.7
1057 * build system: Improved detection of several libraries, especially if
1058 they are in non-standard paths.
1059 * build system: Portability fixes: Automatically define "_REENTRANT"
1060 if the libc expects it.
1061 * collectd: Error and warning messages have been improved.
1062 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1064 * apache plugin: Allocate new memory when reading a webpage instead of
1065 using a buffer of static size.
1066 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1068 * hddtemp plugin: Error and warning messages have been improved.
1069 * sensors plugin: Fix sensor collection for some chip types.
1071 2008-03-29, Version 4.2.6
1072 * collectd: Improved error messages when parsing the configuration.
1073 * sensors plugin: Fix temperature collection with libsensors4.
1074 * unixsock plugin: Fix mixed input and output operation on streams.
1075 * wireless plugin: Fix reading noise value.
1077 2008-03-04, Version 4.2.5
1078 * apache plugin: Improved initialization and error messages.
1079 * exec plugin: Set supplementary group IDs.
1081 + Create separate threads for reading from the socket and parsing
1082 and dispatching incoming packets. Versions prior to this may have
1083 problems in high-load situations, where the socket receive buffers
1084 overflows, resulting in gaps in the data.
1085 + Use `memcpy' when constructing/parsing a package to avoid
1086 alignment problems on weird architectures, such as Sparc.
1087 + Translate doubles to/from the x86 byte representation to ensure
1088 cross-platform compatibility.
1089 * ping plugin: Correct the handling of the `TTL' setting.
1090 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1091 * swap plugin: Reapply a patch for Solaris.
1092 * tcpconns plugin: Portability improvements.
1094 2008-01-21, Version 4.2.4
1095 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1096 the permission on the socket as documented in the manpage. Thanks to
1097 Evgeny Chukreev for fixing this issue.
1098 * collectd: The documentation has been improved.
1100 2007-12-28, Version 4.2.3
1101 * sensors plugin: Updated the plugin to build and work with version 3
1102 of the libsensors library.
1104 2007-12-15, Version 4.2.2
1105 * nginx plugin: Incorrect comparison of strings lead to a segfault
1106 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1108 * logfile plugin: The config option `Timestamp' was handled
1109 incorrectly and basically always active. Thanks to Luke Heberling
1112 2007-11-08, Version 4.2.1
1113 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1114 enabled on the host.
1115 * snmp plugin: Fix a memory leak.
1117 2007-10-27, Version 4.2.0
1118 * collectd: The new config option `Include' lets you include other
1119 configfiles and thus split up your config into smaller parts. This
1120 may be especially interesting for the snmp plugin to keep the data
1121 definitions separate from the host definitions.
1122 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1123 (number of connections, octets and packets for each service and
1124 destination). Thanks to Sebastian Harl for this plugin.
1125 * memcached plugin: The new `memcached' plugin connects to a memcached
1126 daemon process and collects statistics of this distributed caching
1127 system. Thanks to Antony Dovgal for contributing this plugin.
1128 * nginx plugin: The new `nginx' plugin reads the status page of an
1129 nginx daemon and saves the handled connections and requests.
1130 * perl plugin: Many changes, including the added `EnableDebugger'
1131 config option which lets you debug your Perl plugins more easily.
1132 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1133 be more thread-safe otherwise by locking calls to the library.
1134 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1135 correct the values returned by SNMP-agents. If a <data> block is
1136 defined as `table' the instance is now optional. The sequence number
1137 is used as the type-instance in this case. The new `InstancePrefix'
1138 option allows to add arbitrary prefixes to the type-instance.
1139 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1140 certain TCP connections and what state they're in. This can be used
1141 to see how many connections your FTP server has to handle or how
1142 many outgoing connections your mailserver has open.
1144 2008-01-11, Version 4.1.6
1145 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1146 the permission on the socket as documented in the manpage. Thanks to
1147 Evgeny Chukreev for fixing this issue.
1148 * collectd: The documentation has been improved.
1150 2007-12-27, Version 4.1.5
1151 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1153 * sensors plugin: Updated the plugin to build and work with version 3
1154 of the libsensors library.
1156 2007-11-08, Version 4.1.4
1157 * Build system: Improve detection of the rrd library, especially if
1158 it's in a non-standard location.
1159 * Build system: A bug when parsing the argument for
1160 `--with-libnetsnmp' has been fixed.
1161 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1162 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1163 a deadlock or delay when shutting down the daemon.
1164 * snmp plugin: Fix a memory leak.
1166 2007-10-24, Version 4.1.3
1167 * collectd: A build issue under Solaris has been resolved by renaming
1169 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1170 be more thread-safe otherwise by locking calls to the library.
1172 2007-09-28, Version 4.1.2
1173 * apcups plugin: Fix reporting of the `load percent' data.
1174 * wireless plugin: Correct the handling of cards returning signal and
1175 noise quality as percentage.
1176 * perl plugin: Fix a possible buffer overflow in get_module_name().
1177 * build system: Further improve the detection of libraries.
1178 * netlink plugin: Build issues under some older versions of the Linux
1179 includes (i. e. Debian Sarge) have been fixed.
1180 * snmp plugin: Fix a potential segfault when a host times out. Add
1181 support for the `timeticks' type.
1183 2007-09-12, Version 4.1.1
1184 * Build system: The detection of `libnetlink' has been improved.
1185 * collectd: The documentation has been fixed in numerous places.
1186 * exec plugin: Setting the group under which to run a program has been
1188 * collectd: The `sstrerror' function was improved to work correctly
1189 with the broken GNU version of `strerror_r'.
1190 * collectd: Write an error message to STDERR when loading of a plugin
1192 * apcups plugin: Fix the `types' used to submit the values: They still
1193 has an `apcups_' prefix which doesn't work anymore.
1194 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1195 whatever the client thinks is `now'..
1197 2007-09-01, Version 4.1.0
1198 * Build system: The build system has been changed to automatically
1199 disable all plugins, which are missing dependencies. The dependency
1200 checking has been removed from the plugins themselves to remove
1202 * Flexible interval: The interval of collected data is now sent along
1203 with the data itself over the network, so that the interval-settings
1204 of server and clients no longer needs to match.
1205 * netlink plugin: The new `netlink' plugin connects to the Linux
1206 kernel using a netlink socket and uses it to query information about
1207 interfaces, qdiscs and classes.
1208 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1209 to not block data collection.
1210 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1211 network devices, such as switches, routers, thermometers, rack
1212 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1214 * unixsock plugin: Added the `LISTVAL' command.
1215 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1216 of music played with xmms.
1218 2007-09-28, Version 4.0.9
1219 * apcups plugin: Fix reporting of the `load percent' data.
1220 * wireless plugin: Correct the handling of cards returning signal and
1221 noise quality as percentage.
1222 * perl plugin: Fix a possible buffer overflow in get_module_name().
1224 2007-09-12, Version 4.0.8
1225 * collectd: The `sstrerror' function was improved to work correctly
1226 with the broken GNU version of `strerror_r'.
1227 * collectd: Write an error message to STDERR when loading of a plugin
1229 * apcups plugin: Fix the `types' used to submit the values: They still
1230 has an `apcups_' prefix which doesn't work anymore.
1231 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1232 whatever the client thinks is `now'..
1234 2007-08-26, Version 4.0.7
1235 * documentation: Some typos have been fixed and some information has
1237 * build system: Many fixes for detecting libraries in unusual places,
1238 such as on RedHat systems. The affected libraries are `libcurl',
1239 `libmysql', and `libupsclient'.
1240 * network plugin: Allow the `Port' option to be specified as a number
1241 (i. e. without quotes).
1242 * nut plugin: A fix allows linking the nut plugin against
1243 libupsclient, version >= 2.2.0.
1244 * processes plugin: Fix a potential segmentation fault.
1246 2007-07-30, Version 4.0.6
1247 * sensors plugin: Fix the ignorelist functionality: Only the `type
1248 instance' was used to match against the list, but the documentation
1249 told otherwise. This release fixes the code, so it complies with the
1251 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1252 configuration messages will end up in the logging facility.
1253 * conrtib/fedora: The contributed specfile for Fedora has been
1256 2007-07-05, Version 4.0.5
1257 * Portability: More fixes for OpenBSD have been included.
1259 2007-06-24, Version 4.0.4
1260 * cpu plugin: Fixed the Solaris code.
1261 * dns plugin: Fixed a build issue for OpenBSD.
1262 * interface plugin: Fixed the Solaris code.
1263 * load plugin: Fixed the alternative `/proc' Linux code.
1264 * memory plugin: Fixed the Solaris code.
1265 * oconfig: Don't require `-lfl' anymore.
1267 2007-06-19, Version 4.0.3
1268 * cpu plugin: Fix the Darwin / Mac OS X code.
1269 * ping plugin: Use the return value of `getpid', not its address.
1270 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be

1272 * configure: Added `--with-nan-emulation' to aid cross compilation.
1274 2007-06-12, Version 4.0.2
1275 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1276 they're given in numerically form.
1278 2007-06-07, Version 4.0.1
1279 * iptables plugin: A bug in the configuration routine has been fixed.
1280 Setting a comment in the configfile will no longer cause a
1283 2007-06-03, Version 4.0.0
1284 * collectd: The plugin-infrastructure has been changed to allow for
1285 more types of plugins, namely `write' and `log' plugins.
1286 * collectd: The read-function has been changed to read many plugins in
1287 parallel, using threads. Thus, plugins generally need to use
1288 thread-safe functions from now on.
1289 * collectd: The '-t' command line options allows to perform syntax tests
1290 of the configuration file and exit immediately.
1291 * csv plugin: The new `csv' plugin handles output to `comma separated
1293 * rrdtool plugin: The new `rrdtool' plugin handles output to
1294 RRD-files. Data can be cached to combine multiple updates into one
1295 write to increase IO-performance.
1296 * network plugin: The new `network' plugin handles IO via the network.
1297 It implements a different, much more extensible protocol which can
1298 combine many values in one packet, decreasing the number of UDP-
1299 packets being sent. It can read from and send to the network and
1300 with the appropriate configuration even forward packets to other
1302 * unixsock plugin: The new `unixsock' plugin provides an interface to
1303 communicate with the daemon while it is running. Right now the
1304 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1306 * perl plugin: The new `perl' plugin allows you to write extensions
1307 for collectd in the scripting-language Perl.
1308 * logfile plugin: The new `logfile' plugin writes logmessages to files
1309 or STDOUT or STDERR.
1310 * syslog plugin: The new `syslog' plugin sends logmessages to the
1311 system's syslog daemon.
1312 * entropy plugin: The new `entropy' plugin collects the amount of
1313 entropy currently being available to the system.
1314 * exec plugin: The new `exec' plugin forks child processes and reads
1315 back values provided by the forked processes.
1316 * iptables plugin: The new `iptables' plugin reads counters from
1317 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1319 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1320 to Peter Holik for contributing this plugin.
1321 * nut plugin: The new `nut' plugin connects the upsd of the `network
1322 ups tools' and reads information about the connected UPS.
1323 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1324 connections) field was added by Florent Monbillard.
1325 * collectd-nagios: The new `collectd-nagios' binary queries values
1326 from collectd, parses them and exits according to Nagios-standards.
1327 * manpages: The manpages have been improved a lot.
1329 2007-09-28, Version 3.11.7
1330 * wireless plugin: Correct the handling of cards returning signal and
1331 noise quality as percentage.
1333 2007-08-31, Version 3.11.6
1334 * processes plugin: Fix a potential segmentation fault.
1336 2007-05-29, Version 3.11.5
1337 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1338 * ntpd plugin: Fix a potential buffer overflow.
1339 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1340 were accounted as `zombies'.
1342 2007-04-10, Version 3.11.4
1343 * dns plugin: Change the order of includes to make the plugin compile
1346 2007-03-30, Version 3.11.3
1347 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1348 of the unused `COLLECT_KSTAT'.
1350 2007-02-11, Version 3.11.2
1351 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1352 NULL-pointer may have been passed to `printf' which causes a
1353 segfault with some libcs.
1355 2007-02-10, Version 3.11.1
1356 * df plugin: Some wrong defines have been fixed so the plugin works
1357 under Solaris again.
1358 * dns plugin: The usage of a struct has been fixed to work with
1360 * processes plugin: Some missing defines have been added so the plugin
1361 compiles cleanly under FreeBSD and presumably other UNIXes.
1363 2006-12-22, Version 3.11.0
1364 * collectd: The new command line option `-P' makes it easier for
1365 distributors to change the location of PID-files.
1366 * collectd: The daemon shuts down faster now which makes it easier to
1367 write init.d-scripts for it.
1368 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1369 caused problems every now and then.
1370 * df plugin: New config options allow to ignore certain mountpoints,
1371 filesystem types or devices.
1372 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1373 and interprets it. It collects traffic as well as qtype, opcode and
1375 * email plugin: Sebastian Harl has contributed this plugin which
1376 counts received mails in categories (e. g. ham, spam, virus), spam
1377 score (as given by SpamAssassin) and check types.
1378 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1379 uses `mbmon' to gather information from sensors on the motherboard.
1380 * processes plugin: Collect detailed statistics for configured
1381 processes, that's process and thread count, CPU usage, resident
1382 segment size and pagefaults.
1383 * multimeter plugin: Peter Holik contributed a new plugin which
1384 queries multimeters.
1385 * sensors plugin: Lubos Stanek has put much effort into improving this
1386 plugin, including `extended naming', collection of voltage values
1387 and the possibility to ignore certain values.
1389 2006-12-21, Version 3.10.4
1390 * Max Kellermann has identified a bug in the server routine: When
1391 opening a socket fails the daemon will (re)try opening the socket in
1392 an endless loop, ultimately leading to a `EMFILE' error.
1394 2006-11-04, Version 3.10.3
1395 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1396 ntpd's reply was sent in more than one packet, the buffer size was
1397 calculated incorrectly, resulting in the reading of uninitialized or
1400 2006-11-01, Version 3.10.2
1401 * The sample config file has been improved.
1402 * Errors in the manpages have been corrected.
1403 * The ping-plugin now adds hosts during initialization, not during
1404 startup. This speeds up startup when no network connectivity is
1405 available. Also, the hosts are being added later when the network is
1407 * Improved BSD-support for the df-plugin.
1408 * Fixed syntax errors in the swap-plugin for Mac OS X.
1409 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1411 * Don't disable the mysql-plugin if connecting to the database fails
1412 during initialization. Instead, try again in increasing intervals.
1414 2006-07-19, Version 3.10.1
1415 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1416 the apcups cannot be reached, unconnected sockets will pile up and
1417 eventually lead to `Too many open files' errors.
1419 2006-07-09, Version 3.10.0
1420 * The `disk' plugin has been ported to Darwin.
1421 * The `battery' plugin should work on many Apple computers now.
1422 * The `traffic' plugin can now ignore certain interfaces. Also,
1423 statistics for sent/received packets and errors have been added.
1424 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1425 to Anthony Gialluca for contributing this plugin and providing me
1426 with a test environment :)
1427 * A plugin for monitoring an NTP instance and the local clock drift
1430 2006-06-25, Version 3.9.4
1431 * The Solaris code in the `swap' plugin has been changed to reflect
1432 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1434 * The debugging system has been fixed to work with the Sun libc.
1435 * When built without librrd the variable `operating_mode' could be
1436 uninitialized. Thanks to David Elliot for reporting the bug.
1438 2006-06-01, Version 3.9.3
1439 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1440 operating systems also profit from the changes, but I wasn't able to
1442 * Changed the build system to find the netinet-includes under FreeBSD
1443 and therefore successfully build the `liboping' library there.
1445 2006-05-09, Version 3.9.2
1446 * Applied a patch to the `liboping' library. Due to a bug in the
1447 sequence checking the `ping' plugin stopped working after
1448 approximately 7.6 days.
1450 2006-05-09, Version 3.8.5
1451 * Applied a patch to the `liboping' library. Due to a bug in the
1452 sequence checking the `ping' plugin stopped working after
1453 approximately 7.6 days.
1455 2006-04-21, Version 3.9.1
1456 * Build issues with Solaris and possible other architectures have been
1458 * Problems when building the `apache'-plugin without `libcurl' have
1460 * A bug in the `ping' plugin has been fixed. Sorry folks.
1462 2006-04-02, Version 3.9.0
1463 * A plugin to monitor the Apache webserver has been added.
1464 <http://httpd.apache.org/>
1465 * A plugin to collect statistics about virtual servers using VServer.
1466 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1468 * A plugin for wireless LAN cards has been added. It monitors signal
1469 strength, link quality and noise ratio..
1470 * A plugin for Apple hardware sensors has been added.
1471 * An option to compile collectd with different `step' and `heartbeat'
1472 settings has been added. The size of RRAs is no longer static but
1473 calculated based on the settings for `step' and `width'.
1474 * The `ping' plugin can now be configured to use a certain TTL.
1475 * A plugin to monitor the hardware sensors of Apple computers has been
1477 * The plugins `cpu', `memory', `processes' and `traffic' have been
1478 ported to Mach/Darwin (Mac OS X).
1479 * The `log mode' has been contributed by Christophe Kalt. It writes
1480 the data into text files rather than RRD files.
1482 2006-04-09, Version 3.8.4
1483 * Applied patch by Vincent Stehlé which improves the disk-name
1484 resolution in the `hddtemp' plugin for Linux systems.
1486 2006-04-02, Version 3.8.3
1487 * Applied a patch by James Byers: The MySQL plugin was not working
1488 with MySQL 5.0.2 or later.
1490 2006-03-14, Version 3.8.2
1491 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1492 the GNU libc, because it points to `/etc/fstab' rather than
1495 2006-03-13, Version 3.8.1
1496 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1497 * Fixes in the debian `postinst' and `init.d' scripts.
1499 2006-03-09, Version 3.8.0
1500 * The `ping' plugin no longer uses `libping' but a self written
1501 library named `liboping'. With this library it's possible to ping
1502 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1504 2006-02-18, Version 3.7.2
1505 * A simple bug in the `battery' plugin has been fixed. It should now
1506 work with ACPI based batteries as well. Thanks to Sebastian for
1508 * Fixing a bug that prevented collectd to be built without librrd.
1509 Thanks to Werner Heuser for reporting it.
1511 2006-02-04, Version 3.7.1
1512 * The new network code has been improved to build with older versions
1514 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1515 to Tommie Gannert for this patch.
1517 2006-01-30, Version 3.7.0
1518 * The `battery' plugin has been added. It collects information about
1520 * The MySQL plugin has been improved: It now writes two more RRD
1521 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1522 * The `cpufreq' plugin now reads another file since the file it did
1523 read so far causes much overhead in the kernel. Also, you need root
1524 to read the old file, but not to read the new one.
1525 * The `hddtemp' plugin can now be configured to connect to another
1526 address and/or port than localhost.
1527 * The `df' plugin now prefers `statvfs' over `statfs'.
1528 * The network code has been rewritten. collectd now supports unicast
1529 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1530 be set in the configfile.
1532 2006-01-24, Version 3.6.2
1533 * Due to a bug in the configfile handling collectd wouldn't start in
1534 client mode. This released fixes this.
1536 2006-01-20, Version 3.6.1
1537 * Due to a bug in `configure.in' all modules and the binary were
1538 linked against `libmysqlclient'. This issue is solved by this
1541 2006-01-17, Version 3.6.0
1542 * A config file has been added. This allows for loading only specific
1544 * A `df' plugin has been added.
1545 * A `mysql' plugin has been added.
1546 * The `ping' plugin doesn't entirely give up hope when a socket error
1547 occurred, but will back of and increase the intervals between tries.
1549 2006-01-21, Version 3.5.2
1550 * Fixed yet another bug in the signal handling.. Stupid typo..
1551 * Improved the ping plugin to not give up on socket errors (backport
1554 2005-12-18, Version 3.5.1
1555 * The PID-file is now deleted correctly when shutting down the daemon.
1556 * SIGINT and SIGTERM are now handled correctly.
1558 2005-12-16, Version 3.5.0 (Revision 326)
1559 * A bug in the `load' module under Solaris has been fixed.
1560 * The `users' module has been contributed by Sebastian Harl. It counts
1561 currently logged in users.
1562 * The CPU module now works under FreeBSD without the use of
1563 `libstatgrab', however SMP support is missing.
1564 * The default directories for the RRD files and the PID file now
1565 depend on the compile time setting of `localstatedir'.
1567 2005-11-15, Version 3.4.0 (Revision 236)
1568 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1569 from gentoo's bugzilla for writing the patch.
1570 * The build dependency for librrd has been removed. Binaries built
1571 without librrd are client-only and will multicast their value as
1572 with the `-c' argument.
1573 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1574 * The newly introduced `-f' switch prevents daemon initialization
1575 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1576 Barcellos for this patch.
1578 2005-11-04, Version 3.3.0 (Revision 216)
1579 * New modules have been added:
1580 - `serial', for monitoring traffic on the serial interfaces
1581 - `nfs', for graphing NFS procedure calls
1582 - `tape', traffic from/to tape devices
1583 * The memory.rrd now accepts more than 4Gig of memory.
1585 2005-10-26, Version 3.2.0 (Revision 200)
1586 * Support for graphing the processes has been added (thanks to Lyonel
1588 * If reading from hddtemp fails collectd will increase the time
1589 between polls up to one day.
1590 * The init.d files have been improved.
1591 * Problems with the spec file have been fixed.
1593 2005-10-16, Version 3.1.0 (Revision 194)
1594 * Added the `setsid' syscall to the startup code.
1595 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1597 2005-09-30, Version 3.0.0 (Revision 184)
1598 * The ability to send/receive data to/from the network (think
1599 multicast) has been added.
1600 * Modules have been split up into shared libraries can be loaded at
1601 runtime. The biggest advantage is that the core program doesn't need
1602 to be linked against an external library.
1603 * A patch by George Kargiotakis has been applied: It fixes the sensors
1604 behaviour then more than one sensor is being queried.
1606 2005-09-16, Version 2.1.0 (Revision 172)
1607 * A module for swap statistics has been added.
1609 2005-09-09, Version 2.0.0 (Revision 135)
1610 * Filenames can no longer be configured at program startup. The only
1611 options as of this version are the directory and ping hosts.
1612 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1613 Soft-IRQ statistics are added to `System'.
1614 * Diskstats now collect read and write bytes, not sectors.
1615 * Ping statistics can now be collected for more than one host. There
1616 is no default any more: If no host is given no host will be pinged.
1617 * A self-written patch for libping has been applied so it builds
1620 2005-09-01, Version 1.8.1 (Revision 123)
1621 * Much improved configure-script: libraries and features may now be
1623 * More detailed warnings/error messages when RRD update fails.
1625 2005-08-29, Version 1.8.0:
1626 * Support for collecting disk statistics under Solaris.
1628 2005-08-25, Version 1.7.0:
1629 * Support for libstatgrab[1] for load, memory usage and network
1630 traffic. CPU- and disk-usage are not (yet) supported, since
1631 libstatgrab returns insufficient information. I will contact the
1633 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1634 aren't necessarily counted linear which is now handled correctly.
1635 [1]: http://www.i-scream.org/libstatgrab/
1637 2005-08-21, Version 1.6.0:
1638 * Basic support for Solaris: System load and cpu-usage can be
1639 collected under Solaris, too. Other stats will follow later.
1640 * Many fixes in the autoconf-script
1641 * Collection/Museum scripts have been added under contrib/museum
1642 * collectd may now be started in unprivileged mode, though ping
1643 statistics will not work.
1645 2005-07-17, Version 1.5.1:
1646 * Diskstats-RRDs now use major/minor for naming. Some systems have
1647 weird strings as disk-names..
1649 2005-07-17, Version 1.5:
1650 * A new module, diskstats, has been added. It collects information
1651 about the disks and partitions.
1653 2005-07-11, Version 1.4.2:
1654 * The meminfo module has been changed to work with more platforms
1655 and/or kernel versions.
1657 2005-07-10, Version 1.4.1: Correct traffic stats
1658 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1659 forgot to correct when I changed that module.
1661 2005-07-09, Version 1.4: More traffic stats
1662 * Traffic is now collected for all interfaces that can be found
1663 * Temperature-statistics are read from lm-sensors if available
1665 2005-07-08, Version 1.3: CPU stats
1666 * Collecting CPU statistics now
1668 2005-07-12, Version 1.2: Using syslog
1669 * collectd is now using the syslog facility to report errors, warnings
1671 * The default directory is now /var/db/collectd
1673 2005-07-10, Version 1.1: Minor changes
1674 * Nothing really useful to say ;)
1676 2005-07-09, Version 1.0: Initial Version
1677 * The following modules are provided:
