508 2009-09-10, Version 4.6.5
509 * collectd: Remove old values when a cache entry is marked as missing.
510 This way the “GETVAL” command of the UnixSock plugin doesn't return
511 old, no longer valid values when this happens. Thanks to Andrés J.
513 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
514 to follow redirects. Thanks to Joey Hess for reporting this bug.
515 * df plugin: Check the ignorelist before stating the file system,
516 possibly reducing the number of stats considerably. Thanks to Joey
517 Hess for reporting this bug.
518 * iptables plugin: Support for the new libiptc API has been added.

539 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
540 for many fixes and providing a build system for many platforms,
541 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
542 providing an OpenBSD system.
543 * collectd: Two bugs with the threshold checking have been fixed. The
544 first one prevented thresholds to be checked at all, the second one
545 caused wrong behavior with the persistency option. Thanks to Andrés
546 J. Díaz for fixing these problems.
547 * collectd: Handling of the `Include' configuration option has been
549 * battery plugin: Don't complain about a missing directory every

567 name which prevented this match to be used as documented. Thanks to
568 Bruno Prémont for finding this problem.
569 * bind plugin: Fix collection of the cached RR sets. The number of RR
570 sets currently in the cache was collected as a counter value, which
571 is nonsense. Thanks to Bruno Prémont for implementing this.
572 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
573 primarily BSDs, don't take it well and crash.
574 * oracle plugin: Portability to 64 bit systems has been improved.
575 * postgresql plugin: The default configuration has been improved.
576 * rrdtool plugin: Fix a possible race condition: If the network plugin

591 user to use `matches' and `targets' to control value processing.
592 * collectd: The new `-T' command line argument allows more in-depth
593 testing of a configuration. Thanks to Doug MacEachern for the patch.
594 * collectd-nagios: The Nagios integration command has been updated to
595 use libcollectdclient. The `percentage' aggregation function has
596 been added. Thanks to Fabian Linzberger for the patch.
597 * libcollectdclient: A library which abstracts communication with the
598 unixsock plugin for clients has been added.

608 statistics, allowing very detailed name server statistics. Thanks to
609 Bruno Prémont for this plugin.
610 * cpu plugin: Report `interrupt' separately when using
611 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
612 example for native OpenBSD support, has been added. Thanks to Simon
613 Kuhnle for the patch.
614 * csv plugin: Make it possible to write values to STDOUT instead of
615 files. This is meant for testing purposes mostly. The output written
616 to STDOUT is compatible with the exec plugin. Thanks to Doug
617 MacEachern for the patch.
618 * curl plugin: This new plugin can be used to read web pages and parse
619 them using the same mechanism that's used in the tail plugin.
620 * dbi plugin: This new plugin allows you to connect to a variety of
621 relational databases and use SQL to gather custom statistics from
622 it. It is similar to the already existing PostgreSQL plugin but uses
623 libdbi to communicate with the database(s).
624 * interface plugin: Use the ignorelist framework when selecting /
625 ignoring interfaces. This allows one to use regular expressions to
626 select interfaces, too.
627 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
628 Thanks to Bruno Prémont for this patch.
629 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
631 * mysql plugin: Allow connecting to a database via the UNIX domain
632 socket, too. Thanks to Mirko Buffoni for the patch.

645 allowing plugins to register `matches' and `targets'.
646 * postgresql plugin: The preferred configuration syntax has been
647 updated to be in line with the syntax used by the new dbi and oracle
648 plugins. The compatibility code for the old syntax is present.
649 Support for the new `Result' blocks and the interval parameter has
651 * processes plugin: Stacksize and virtual memory usage statistics have
652 been added. Portability fixes.
653 * rrdcached plugin: This new plugin uses the (still in development)
654 RRD accelerator daemon, rrdcached. This daemon works very similar to
655 the original rrdtool plugin of collectd, but adds some more nice
657 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
660 2009-05-09, Version 4.5.4
661 * Build system, various plugins: Many build fixes for FreeBSD,
662 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern

691 code. Thanks to "thated" for reporting this.
693 2009-01-02, Version 4.5.2
694 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
695 file may be in both locations, especially when the database was
696 installed in a non-standard path. Thanks to Dusty Doris for
698 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
699 Solaris, in the configure script automatically.
700 * build system, tcpconns plugin: Check for `kvm_nlist' and
701 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
702 library with similar functions to the BSD variant, but doesn't
703 provide these necessary functions.
704 * collectd.conf(5): Various fixes and clarifications.
705 * collectd: Remove a GNUism (unnamed unions), thus improving

712 * network plugin: Fix the handling of `type' in the network protocol.
713 Due to a programming mistake, only 4 or 8 bytes would be copied to a
714 much larger buffer. This caused the `type' to be transferred much
715 more often than necessary. In some cases, e. g. the `cpu' and
716 `cpufreq' plugins being used at the same time, data may be corrupted
717 in those files. Thanks to Bruno Prémont for debugging and reporting
719 * processes plugin: Fix a possible segmentation fault when specifying
720 invalid configuration options.
721 * unixsock plugin: Make sure the initialization function is run only
722 once. This resolves a file descriptor leak under systems which run
723 the initialization more than once, such as Solaris.
725 2008-10-16, Version 4.5.1
726 * build system: Change `--enable-<plugin>' to abort with an error if
727 dependencies are not met. Thanks to Bruno Prémont for the patch.
728 Also, the poisoning of various string functions has been restricted
730 * collectd: Fix a memory leak in the global value cache. With every
731 *missing* value a couple of bytes would be leaked. Another memory
732 leak in the configuration handling code has been fixed. Thanks to
733 Niraj Tolia for reporting these issues.
734 * collectd: Fix an off-by-one error in the ignorelist functionality.
735 When using regular expressions, the last character would be missing,
736 possibly matching differently from what one would expect.
737 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
739 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
740 Linzberger for reporting the bug.
741 * iptables plugin: Fix an off-by-one error. If a string was just one
742 character too long, it was truncated instead of reporting an error.
743 * network plugin: Fix a memory leak in the configuration handling
744 code. Thanks to Niraj Tolia for reporting this issue.
745 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
746 * postgresql plugin: Don't reopen connection during reinitialization.
747 This fixes a bug under Solaris and potentially other platforms.

749 leaks. Thanks to ``Admin'' for reporting these bugs.
750 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
752 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
753 problems with some `libc's. Thanks to Matthias Lay for reporting the
756 2008-09-04, Version 4.5.0
757 * collectd: Added the ability to flush certain identifiers.

770 such as temperatures, from sensors connected to the computer via the
772 * perl plugin: Improved synchronized access to internal data structures
773 and fixed a possible dead-lock.
774 * perl plugin: Added the ability to flush certain identifiers and marked
775 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
777 * perl plugin: Added the ability to configure Perl plugins.

785 using Linux ACPI thermal zone data.
787 2009-01-02, Version 4.4.5
788 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
789 file may be in both locations, especially when the database was
790 installed in a non-standard path. Thanks to Dusty Doris for
792 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
793 Solaris, in the configure script automatically.
794 * collectd.conf(5): Various fixes and clarifications.
795 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
796 portability problems, especially for Solaris.
797 * dns plugin: Fix a portability problem with NetBSD.
798 * network plugin: Fix the handling of `type' in the network protocol.
799 Due to a programming mistake, only 4 or 8 bytes would be copied to a
800 much larger buffer. This caused the `type' to be transferred much
801 more often than necessary. In some cases, e. g. the `cpu' and
802 `cpufreq' plugins being used at the same time, data may be corrupted
803 in those files. Thanks to Bruno Prémont for debugging and reporting
805 * unixsock plugin: Make sure the initialization function is run only
806 once. This resolves a file descriptor leak under systems which run
807 the initialization more than once, such as Solaris.
809 2008-10-16, Version 4.4.4
810 * build system: Change `--enable-<plugin>' to abort with an error if
811 dependencies are not met. Thanks to Bruno Prémont for the patch.
812 Also, the poisoning of various string functions has been restricted

871 exec plugins. This command can be used to force a plugin (or all) to
872 flush its values to disk.
873 * collectd: Thresholds can now be configured to apply to one data
874 source only, making it possible to configure different thresholds
875 for each data source.

885 sensor values via IPMI, the intelligent platform management
887 * iptables plugin: The iptc library that is used by the iptables
888 plugin has been added to the distribution, because it is not
889 provided by all distributions and removed from at least one.
890 * powerdns plugin: The new powerdns plugin reads statistics from an
891 authoritative or a recursing PowerDNS name server.
892 * rrdtool plugin: The size of the files generated with the default
893 configuration has been decreased.
894 * tail plugin: The new tail plugin can be used to gather statistics by

958 are status messages that may be associated with a data instance.
959 * collectd: Threshold checking has been added to the daemon. This
960 means that you can configure threshold values for each data
961 instance. If this threshold is exceeded a notification will be
963 * collectd: The new `FQDNLookup' option tells the daemon to use the
964 full qualified domain name as the hostname, not just the host part
965 es returned by `gethostname(2)'.
966 * collectd: Support for more than one `TypesDB' file has been added.
967 This is useful when one such file is included in a package but one
968 wants to add custom type definitions.
969 * collectd: The `Include' config option has been expanded to handle
970 entire directories and shell wildcards.
971 * collectdmon: The new `collectdmon' binary detects when collectd

981 domain name lookups in this plugin.
982 * perl plugin: Many internal changes added support for handling multiple
983 threads making the plugin reasonably usable inside collectd. The API has
984 been extended to support notifications and export global variables to
985 Perl plugins; callbacks now have to be identified by name rather than a
986 pointer to a subroutine. The plugin is no longer experimental.
987 * uuid plugin: The new UUID plugin sets the hostname to an unique
988 identifier for this host. This is meant for setups where each client
989 may migrate to another physical host, possibly going through one or
990 more name changes in the process. Thanks to Richard Jones from
991 Red Hat's Emerging Technology group for this plugin.
992 * libvirt: The new libvirt plugin uses the `libvirt' library to query
993 CPU, disk and network statistics about guest systems on the same
994 physical server. Thanks to Richard Jones from Red Hat's Emerging
995 Technology group for this plugin.
997 2008-04-22, Version 4.2.7
998 * build system: Improved detection of several libraries, especially if
999 they are in non-standard paths.
1000 * build system: Portability fixes: Automatically define "_REENTRANT"
1001 if the libc expects it.
1002 * collectd: Error and warning messages have been improved.
1003 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1005 * apache plugin: Allocate new memory when reading a webpage instead of
1006 using a buffer of static size.
1007 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1009 * hddtemp plugin: Error and warning messages have been improved.
1010 * sensors plugin: Fix sensor collection for some chip types.
1012 2008-03-29, Version 4.2.6
1013 * collectd: Improved error messages when parsing the configuration.
1014 * sensors plugin: Fix temperature collection with libsensors4.
1015 * unixsock plugin: Fix mixed input and output operation on streams.
1016 * wireless plugin: Fix reading noise value.
1018 2008-03-04, Version 4.2.5
1019 * apache plugin: Improved initialization and error messages.
1020 * exec plugin: Set supplementary group IDs.
1022 + Create separate threads for reading from the socket and parsing
1023 and dispatching incoming packets. Versions prior to this may have
1024 problems in high-load situations, where the socket receive buffers
1025 overflows, resulting in gaps in the data.
1026 + Use `memcpy' when constructing/parsing a package to avoid
1027 alignment problems on weird architectures, such as Sparc.
1028 + Translate doubles to/from the x86 byte representation to ensure
1029 cross-platform compatibility.
1030 * ping plugin: Correct the handling of the `TTL' setting.
1031 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1032 * swap plugin: Reapply a patch for Solaris.
1033 * tcpconns plugin: Portability improvements.
1035 2008-01-21, Version 4.2.4
1036 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1037 the permission on the socket as documented in the manpage. Thanks to
1038 Evgeny Chukreev for fixing this issue.
1039 * collectd: The documentation has been improved.
1041 2007-12-28, Version 4.2.3
1042 * sensors plugin: Updated the plugin to build and work with version 3
1043 of the libsensors library.
1045 2007-12-15, Version 4.2.2
1046 * nginx plugin: Incorrect comparison of strings lead to a segfault
1047 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1049 * logfile plugin: The config option `Timestamp' was handled
1050 incorrectly and basically always active. Thanks to Luke Heberling
1053 2007-11-08, Version 4.2.1
1054 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1055 enabled on the host.
1056 * snmp plugin: Fix a memory leak.
1058 2007-10-27, Version 4.2.0
1059 * collectd: The new config option `Include' lets you include other
1060 configfiles and thus split up your config into smaller parts. This
1061 may be especially interesting for the snmp plugin to keep the data
1062 definitions separate from the host definitions.
1063 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1064 (number of connections, octets and packets for each service and
1065 destination). Thanks to Sebastian Harl for this plugin.
1066 * memcached plugin: The new `memcached' plugin connects to a memcached
1067 daemon process and collects statistics of this distributed caching
1068 system. Thanks to Antony Dovgal for contributing this plugin.
1069 * nginx plugin: The new `nginx' plugin reads the status page of an
1070 nginx daemon and saves the handled connections and requests.
1071 * perl plugin: Many changes, including the added `EnableDebugger'
1072 config option which lets you debug your Perl plugins more easily.
1073 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1074 be more thread-safe otherwise by locking calls to the library.
1075 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1076 correct the values returned by SNMP-agents. If a <data> block is
1077 defined as `table' the instance is now optional. The sequence number
1078 is used as the type-instance in this case. The new `InstancePrefix'
1079 option allows to add arbitrary prefixes to the type-instance.
1080 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1081 certain TCP connections and what state they're in. This can be used
1082 to see how many connections your FTP server has to handle or how
1083 many outgoing connections your mailserver has open.
1085 2008-01-11, Version 4.1.6
1086 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1087 the permission on the socket as documented in the manpage. Thanks to
1088 Evgeny Chukreev for fixing this issue.
1089 * collectd: The documentation has been improved.
1091 2007-12-27, Version 4.1.5
1092 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1094 * sensors plugin: Updated the plugin to build and work with version 3
1095 of the libsensors library.
1097 2007-11-08, Version 4.1.4
1098 * Build system: Improve detection of the rrd library, especially if
1099 it's in a non-standard location.
1100 * Build system: A bug when parsing the argument for
1101 `--with-libnetsnmp' has been fixed.
1102 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1103 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1104 a deadlock or delay when shutting down the daemon.
1105 * snmp plugin: Fix a memory leak.
1107 2007-10-24, Version 4.1.3
1108 * collectd: A build issue under Solaris has been resolved by renaming
1110 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1111 be more thread-safe otherwise by locking calls to the library.
1113 2007-09-28, Version 4.1.2
1114 * apcups plugin: Fix reporting of the `load percent' data.
1115 * wireless plugin: Correct the handling of cards returning signal and
1116 noise quality as percentage.
1117 * perl plugin: Fix a possible buffer overflow in get_module_name().
1118 * build system: Further improve the detection of libraries.
1119 * netlink plugin: Build issues under some older versions of the Linux
1120 includes (i. e. Debian Sarge) have been fixed.
1121 * snmp plugin: Fix a potential segfault when a host times out. Add
1122 support for the `timeticks' type.
1124 2007-09-12, Version 4.1.1
1125 * Build system: The detection of `libnetlink' has been improved.
1126 * collectd: The documentation has been fixed in numerous places.
1127 * exec plugin: Setting the group under which to run a program has been
1129 * collectd: The `sstrerror' function was improved to work correctly
1130 with the broken GNU version of `strerror_r'.
1131 * collectd: Write an error message to STDERR when loading of a plugin
1133 * apcups plugin: Fix the `types' used to submit the values: They still
1134 has an `apcups_' prefix which doesn't work anymore.
1135 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1136 whatever the client thinks is `now'..
1138 2007-09-01, Version 4.1.0
1139 * Build system: The build system has been changed to automatically
1140 disable all plugins, which are missing dependencies. The dependency
1141 checking has been removed from the plugins themselves to remove
1143 * Flexible interval: The interval of collected data is now sent along
1144 with the data itself over the network, so that the interval-settings
1145 of server and clients no longer needs to match.
1146 * netlink plugin: The new `netlink' plugin connects to the Linux
1147 kernel using a netlink socket and uses it to query information about
1148 interfaces, qdiscs and classes.
1149 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1150 to not block data collection.
1151 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1152 network devices, such as switches, routers, thermometers, rack
1153 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1155 * unixsock plugin: Added the `LISTVAL' command.
1156 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1157 of music played with xmms.
1159 2007-09-28, Version 4.0.9
1160 * apcups plugin: Fix reporting of the `load percent' data.
1161 * wireless plugin: Correct the handling of cards returning signal and
1162 noise quality as percentage.
1163 * perl plugin: Fix a possible buffer overflow in get_module_name().
1165 2007-09-12, Version 4.0.8
1166 * collectd: The `sstrerror' function was improved to work correctly
1167 with the broken GNU version of `strerror_r'.
1168 * collectd: Write an error message to STDERR when loading of a plugin
1170 * apcups plugin: Fix the `types' used to submit the values: They still
1171 has an `apcups_' prefix which doesn't work anymore.
1172 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1173 whatever the client thinks is `now'..
1175 2007-08-26, Version 4.0.7
1176 * documentation: Some typos have been fixed and some information has
1178 * build system: Many fixes for detecting libraries in unusual places,
1179 such as on RedHat systems. The affected libraries are `libcurl',
1180 `libmysql', and `libupsclient'.
1181 * network plugin: Allow the `Port' option to be specified as a number
1182 (i. e. without quotes).
1183 * nut plugin: A fix allows linking the nut plugin against
1184 libupsclient, version >= 2.2.0.
1185 * processes plugin: Fix a potential segmentation fault.
1187 2007-07-30, Version 4.0.6
1188 * sensors plugin: Fix the ignorelist functionality: Only the `type
1189 instance' was used to match against the list, but the documentation
1190 told otherwise. This release fixes the code, so it complies with the
1192 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1193 configuration messages will end up in the logging facility.
1194 * conrtib/fedora: The contributed specfile for Fedora has been
1197 2007-07-05, Version 4.0.5
1198 * Portability: More fixes for OpenBSD have been included.
1200 2007-06-24, Version 4.0.4
1201 * cpu plugin: Fixed the Solaris code.
1202 * dns plugin: Fixed a build issue for OpenBSD.
1203 * interface plugin: Fixed the Solaris code.
1204 * load plugin: Fixed the alternative `/proc' Linux code.
1205 * memory plugin: Fixed the Solaris code.
1206 * oconfig: Don't require `-lfl' anymore.
1208 2007-06-19, Version 4.0.3
1209 * cpu plugin: Fix the Darwin / Mac OS X code.
1210 * ping plugin: Use the return value of `getpid', not its address.
1211 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1212 initialized correctly.
1213 * configure: Added `--with-nan-emulation' to aid cross compilation.
1215 2007-06-12, Version 4.0.2
1216 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1217 they're given in numerically form.
1219 2007-06-07, Version 4.0.1
1220 * iptables plugin: A bug in the configuration routine has been fixed.
1221 Setting a comment in the configfile will no longer cause a
1224 2007-06-03, Version 4.0.0
1225 * collectd: The plugin-infrastructure has been changed to allow for
1226 more types of plugins, namely `write' and `log' plugins.
1227 * collectd: The read-function has been changed to read many plugins in
1228 parallel, using threads. Thus, plugins generally need to use
1229 thread-safe functions from now on.
1230 * collectd: The '-t' command line options allows to perform syntax tests
1231 of the configuration file and exit immediately.
1232 * csv plugin: The new `csv' plugin handles output to `comma separated
1234 * rrdtool plugin: The new `rrdtool' plugin handles output to
1235 RRD-files. Data can be cached to combine multiple updates into one
1236 write to increase IO-performance.
1237 * network plugin: The new `network' plugin handles IO via the network.
1238 It implements a different, much more extensible protocol which can
1239 combine many values in one packet, decreasing the number of UDP-
1240 packets being sent. It can read from and send to the network and
1241 with the appropriate configuration even forward packets to other
1243 * unixsock plugin: The new `unixsock' plugin provides an interface to
1244 communicate with the daemon while it is running. Right now the
1245 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1247 * perl plugin: The new `perl' plugin allows you to write extensions
1248 for collectd in the scripting-language Perl.
1249 * logfile plugin: The new `logfile' plugin writes logmessages to files
1250 or STDOUT or STDERR.
1251 * syslog plugin: The new `syslog' plugin sends logmessages to the
1252 system's syslog daemon.
1253 * entropy plugin: The new `entropy' plugin collects the amount of
1254 entropy currently being available to the system.
1255 * exec plugin: The new `exec' plugin forks child processes and reads
1256 back values provided by the forked processes.
1257 * iptables plugin: The new `iptables' plugin reads counters from
1258 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1260 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1261 to Peter Holik for contributing this plugin.
1262 * nut plugin: The new `nut' plugin connects the upsd of the `network
1263 ups tools' and reads information about the connected UPS.
1264 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1265 connections) field was added by Florent Monbillard.
1266 * collectd-nagios: The new `collectd-nagios' binary queries values
1267 from collectd, parses them and exits according to Nagios-standards.
1268 * manpages: The manpages have been improved a lot.
1270 2007-09-28, Version 3.11.7
1271 * wireless plugin: Correct the handling of cards returning signal and
1272 noise quality as percentage.
1274 2007-08-31, Version 3.11.6
1275 * processes plugin: Fix a potential segmentation fault.
1277 2007-05-29, Version 3.11.5
1278 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1279 * ntpd plugin: Fix a potential buffer overflow.
1280 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1281 were accounted as `zombies'.
1283 2007-04-10, Version 3.11.4
1284 * dns plugin: Change the order of includes to make the plugin compile
1287 2007-03-30, Version 3.11.3
1288 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1289 of the unused `COLLECT_KSTAT'.
1291 2007-02-11, Version 3.11.2
1292 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1293 NULL-pointer may have been passed to `printf' which causes a
1294 segfault with some libcs.
1296 2007-02-10, Version 3.11.1
1297 * df plugin: Some wrong defines have been fixed so the plugin works
1298 under Solaris again.
1299 * dns plugin: The usage of a struct has been fixed to work with
1301 * processes plugin: Some missing defines have been added so the plugin
1302 compiles cleanly under FreeBSD and presumably other UNIXes.
1304 2006-12-22, Version 3.11.0
1305 * collectd: The new command line option `-P' makes it easier for
1306 distributors to change the location of PID-files.
1307 * collectd: The daemon shuts down faster now which makes it easier to
1308 write init.d-scripts for it.
1309 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1310 caused problems every now and then.
1311 * df plugin: New config options allow to ignore certain mountpoints,
1312 filesystem types or devices.
1313 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1314 and interprets it. It collects traffic as well as qtype, opcode and
1316 * email plugin: Sebastian Harl has contributed this plugin which
1317 counts received mails in categories (e. g. ham, spam, virus), spam
1318 score (as given by SpamAssassin) and check types.
1319 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1320 uses `mbmon' to gather information from sensors on the motherboard.
1321 * processes plugin: Collect detailed statistics for configured
1322 processes, that's process and thread count, CPU usage, resident
1323 segment size and pagefaults.
1324 * multimeter plugin: Peter Holik contributed a new plugin which
1325 queries multimeters.
1326 * sensors plugin: Lubos Stanek has put much effort into improving this
1327 plugin, including `extended naming', collection of voltage values
1328 and the possibility to ignore certain values.
1330 2006-12-21, Version 3.10.4
1331 * Max Kellermann has identified a bug in the server routine: When
1332 opening a socket fails the daemon will (re)try opening the socket in
1333 an endless loop, ultimately leading to a `EMFILE' error.
1335 2006-11-04, Version 3.10.3
1336 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1337 ntpd's reply was sent in more than one packet, the buffer size was
1338 calculated incorrectly, resulting in the reading of uninitialized or
1341 2006-11-01, Version 3.10.2
1342 * The sample config file has been improved.
1343 * Errors in the manpages have been corrected.
1344 * The ping-plugin now adds hosts during initialization, not during
1345 startup. This speeds up startup when no network connectivity is
1346 available. Also, the hosts are being added later when the network is
1348 * Improved BSD-support for the df-plugin.
1349 * Fixed syntax errors in the swap-plugin for Mac OS X.
1350 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1352 * Don't disable the mysql-plugin if connecting to the database fails
1353 during initialization. Instead, try again in increasing intervals.
1355 2006-07-19, Version 3.10.1
1356 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1357 the apcups cannot be reached, unconnected sockets will pile up and
1358 eventually lead to `Too many open files' errors.
1360 2006-07-09, Version 3.10.0
1361 * The `disk' plugin has been ported to Darwin.
1362 * The `battery' plugin should work on many Apple computers now.
1363 * The `traffic' plugin can now ignore certain interfaces. Also,
1364 statistics for sent/received packets and errors have been added.
1365 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1366 to Anthony Gialluca for contributing this plugin and providing me
1367 with a test environment :)
1368 * A plugin for monitoring an NTP instance and the local clock drift
1371 2006-06-25, Version 3.9.4
1372 * The Solaris code in the `swap' plugin has been changed to reflect
1373 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1375 * The debugging system has been fixed to work with the Sun libc.
1376 * When built without librrd the variable `operating_mode' could be
1377 uninitialized. Thanks to David Elliot for reporting the bug.
1379 2006-06-01, Version 3.9.3
1380 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1381 operating systems also profit from the changes, but I wasn't able to
1383 * Changed the build system to find the netinet-includes under FreeBSD
1384 and therefore successfully build the `liboping' library there.
1386 2006-05-09, Version 3.9.2
1387 * Applied a patch to the `liboping' library. Due to a bug in the
1388 sequence checking the `ping' plugin stopped working after
1389 approximately 7.6 days.
1391 2006-05-09, Version 3.8.5
1392 * Applied a patch to the `liboping' library. Due to a bug in the
1393 sequence checking the `ping' plugin stopped working after
1394 approximately 7.6 days.
1396 2006-04-21, Version 3.9.1
1397 * Build issues with Solaris and possible other architectures have been
1399 * Problems when building the `apache'-plugin without `libcurl' have
1401 * A bug in the `ping' plugin has been fixed. Sorry folks.
1403 2006-04-02, Version 3.9.0
1404 * A plugin to monitor the Apache webserver has been added.
1405 <http://httpd.apache.org/>
1406 * A plugin to collect statistics about virtual servers using VServer.
1407 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1409 * A plugin for wireless LAN cards has been added. It monitors signal
1410 strength, link quality and noise ratio..
1411 * A plugin for Apple hardware sensors has been added.
1412 * An option to compile collectd with different `step' and `heartbeat'
1413 settings has been added. The size of RRAs is no longer static but
1414 calculated based on the settings for `step' and `width'.
1415 * The `ping' plugin can now be configured to use a certain TTL.
1416 * A plugin to monitor the hardware sensors of Apple computers has been
1418 * The plugins `cpu', `memory', `processes' and `traffic' have been
1419 ported to Mach/Darwin (Mac OS X).
1420 * The `log mode' has been contributed by Christophe Kalt. It writes
1421 the data into text files rather than RRD files.
1423 2006-04-09, Version 3.8.4
1424 * Applied patch by Vincent Stehlé which improves the disk-name
1425 resolution in the `hddtemp' plugin for Linux systems.
1427 2006-04-02, Version 3.8.3
1428 * Applied a patch by James Byers: The MySQL plugin was not working
1429 with MySQL 5.0.2 or later.
1431 2006-03-14, Version 3.8.2
1432 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1433 the GNU libc, because it points to `/etc/fstab' rather than
1436 2006-03-13, Version 3.8.1
1437 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1438 * Fixes in the debian `postinst' and `init.d' scripts.
1440 2006-03-09, Version 3.8.0
1441 * The `ping' plugin no longer uses `libping' but a self written
1442 library named `liboping'. With this library it's possible to ping
1443 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1445 2006-02-18, Version 3.7.2
1446 * A simple bug in the `battery' plugin has been fixed. It should now
1447 work with ACPI based batteries as well. Thanks to Sebastian for
1449 * Fixing a bug that prevented collectd to be built without librrd.
1450 Thanks to Werner Heuser for reporting it.
1452 2006-02-04, Version 3.7.1
1453 * The new network code has been improved to build with older versions
1455 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1456 to Tommie Gannert for this patch.
1458 2006-01-30, Version 3.7.0
1459 * The `battery' plugin has been added. It collects information about
1461 * The MySQL plugin has been improved: It now writes two more RRD
1462 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1463 * The `cpufreq' plugin now reads another file since the file it did
1464 read so far causes much overhead in the kernel. Also, you need root
1465 to read the old file, but not to read the new one.
1466 * The `hddtemp' plugin can now be configured to connect to another
1467 address and/or port than localhost.
1468 * The `df' plugin now prefers `statvfs' over `statfs'.
1469 * The network code has been rewritten. collectd now supports unicast
1470 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1471 be set in the configfile.
1473 2006-01-24, Version 3.6.2
1474 * Due to a bug in the configfile handling collectd wouldn't start in
1475 client mode. This released fixes this.
1477 2006-01-20, Version 3.6.1
1478 * Due to a bug in `configure.in' all modules and the binary were
1479 linked against `libmysqlclient'. This issue is solved by this
1482 2006-01-17, Version 3.6.0
1483 * A config file has been added. This allows for loading only specific
1485 * A `df' plugin has been added.
1486 * A `mysql' plugin has been added.
1487 * The `ping' plugin doesn't entirely give up hope when a socket error
1488 occurred, but will back of and increase the intervals between tries.
1490 2006-01-21, Version 3.5.2
1491 * Fixed yet another bug in the signal handling.. Stupid typo..
1492 * Improved the ping plugin to not give up on socket errors (backport
1495 2005-12-18, Version 3.5.1
1496 * The PID-file is now deleted correctly when shutting down the daemon.
1497 * SIGINT and SIGTERM are now handled correctly.
1499 2005-12-16, Version 3.5.0 (Revision 326)
1500 * A bug in the `load' module under Solaris has been fixed.
1501 * The `users' module has been contributed by Sebastian Harl. It counts
1502 currently logged in users.
1503 * The CPU module now works under FreeBSD without the use of
1504 `libstatgrab', however SMP support is missing.
1505 * The default directories for the RRD files and the PID file now
1506 depend on the compile time setting of `localstatedir'.
1508 2005-11-15, Version 3.4.0 (Revision 236)
1509 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1510 from gentoo's bugzilla for writing the patch.
1511 * The build dependency for librrd has been removed. Binaries built
1512 without librrd are client-only and will multicast their value as
1513 with the `-c' argument.
1514 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1515 * The newly introduced `-f' switch prevents daemon initialization
1516 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1517 Barcellos for this patch.
1519 2005-11-04, Version 3.3.0 (Revision 216)
1520 * New modules have been added:
1521 - `serial', for monitoring traffic on the serial interfaces
1522 - `nfs', for graphing NFS procedure calls
1523 - `tape', traffic from/to tape devices
1524 * The memory.rrd now accepts more than 4Gig of memory.
1526 2005-10-26, Version 3.2.0 (Revision 200)
1527 * Support for graphing the processes has been added (thanks to Lyonel
1529 * If reading from hddtemp fails collectd will increase the time
1530 between polls up to one day.
1531 * The init.d files have been improved.
1532 * Problems with the spec file have been fixed.
1534 2005-10-16, Version 3.1.0 (Revision 194)
1535 * Added the `setsid' syscall to the startup code.
1536 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1538 2005-09-30, Version 3.0.0 (Revision 184)
1539 * The ability to send/receive data to/from the network (think
1540 multicast) has been added.
1541 * Modules have been split up into shared libraries can be loaded at
1542 runtime. The biggest advantage is that the core program doesn't need
1543 to be linked against an external library.
1544 * A patch by George Kargiotakis has been applied: It fixes the sensors
1545 behaviour then more than one sensor is being queried.
1547 2005-09-16, Version 2.1.0 (Revision 172)
1548 * A module for swap statistics has been added.
1550 2005-09-09, Version 2.0.0 (Revision 135)
1551 * Filenames can no longer be configured at program startup. The only
1552 options as of this version are the directory and ping hosts.
1553 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1554 Soft-IRQ statistics are added to `System'.
1555 * Diskstats now collect read and write bytes, not sectors.
1556 * Ping statistics can now be collected for more than one host. There
1557 is no default any more: If no host is given no host will be pinged.
1558 * A self-written patch for libping has been applied so it builds
1561 2005-09-01, Version 1.8.1 (Revision 123)
1562 * Much improved configure-script: libraries and features may now be
1564 * More detailed warnings/error messages when RRD update fails.
1566 2005-08-29, Version 1.8.0:
1567 * Support for collecting disk statistics under Solaris.
1569 2005-08-25, Version 1.7.0:
1570 * Support for libstatgrab[1] for load, memory usage and network
1571 traffic. CPU- and disk-usage are not (yet) supported, since
1572 libstatgrab returns insufficient information. I will contact the
1574 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1575 aren't necessarily counted linear which is now handled correctly.
1576 [1]: http://www.i-scream.org/libstatgrab/
1578 2005-08-21, Version 1.6.0:
1579 * Basic support for Solaris: System load and cpu-usage can be
1580 collected under Solaris, too. Other stats will follow later.
1581 * Many fixes in the autoconf-script
1582 * Collection/Museum scripts have been added under contrib/museum
1583 * collectd may now be started in unprivileged mode, though ping
1584 statistics will not work.
1586 2005-07-17, Version 1.5.1:
1587 * Diskstats-RRDs now use major/minor for naming. Some systems have
1588 weird strings as disk-names..
1590 2005-07-17, Version 1.5:
1591 * A new module, diskstats, has been added. It collects information
1592 about the disks and partitions.
1594 2005-07-11, Version 1.4.2:
1595 * The meminfo module has been changed to work with more platforms
1596 and/or kernel versions.
1598 2005-07-10, Version 1.4.1: Correct traffic stats
1599 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1600 forgot to correct when I changed that module.
1602 2005-07-09, Version 1.4: More traffic stats
1603 * Traffic is now collected for all interfaces that can be found
1604 * Temperature-statistics are read from lm-sensors if available
1606 2005-07-08, Version 1.3: CPU stats
1607 * Collecting CPU statistics now
1609 2005-07-12, Version 1.2: Using syslog
1610 * collectd is now using the syslog facility to report errors, warnings
1612 * The default directory is now /var/db/collectd
1614 2005-07-10, Version 1.1: Minor changes
1615 * Nothing really useful to say ;)
1617 2005-07-09, Version 1.0: Initial Version
1618 * The following modules are provided:
