1855 2009-09-10, Version 4.6.5
1856 * collectd: Remove old values when a cache entry is marked as missing.
1857 This way the “GETVAL” command of the UnixSock plugin doesn't return
1858 old, no longer valid values when this happens. Thanks to Andrés J.
1860 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1861 to follow redirects. Thanks to Joey Hess for reporting this bug.

1887 for many fixes and providing a build system for many platforms,
1888 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1889 providing an OpenBSD system.
1890 * collectd: Two bugs with the threshold checking have been fixed. The
1891 first one prevented thresholds to be checked at all, the second one
1892 caused wrong behavior with the persistency option. Thanks to Andrés
1893 J. Díaz for fixing these problems.
1894 * collectd: Handling of the `Include' configuration option has been
1896 * battery plugin: Don't complain about a missing directory every

1910 * filter subsystem: Allow `Chains' without default targets.
1911 * liboping: A patch to comply with strict aliasing rules has been
1913 * timediff match: Fix a typo: The match was registered with a wrong
1914 name which prevented this match to be used as documented. Thanks to
1915 Bruno Prémont for finding this problem.
1916 * bind plugin: Fix collection of the cached RR sets. The number of RR
1917 sets currently in the cache was collected as a counter value, which
1918 is nonsense. Thanks to Bruno Prémont for implementing this.
1919 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1920 primarily BSDs, don't take it well and crash.
1921 * oracle plugin: Portability to 64 bit systems has been improved.
1922 * postgresql plugin: The default configuration has been improved.
1923 * rrdtool plugin: Fix a possible race condition: If the network plugin

1934 faults. Thanks to Peter Holik for his patch.
1936 2009-02-16, Version 4.6.0
1937 * collectd: Added the `filter chain' infrastructure, which allows the
1938 user to use `matches' and `targets' to control value processing.
1939 * collectd: The new `-T' command line argument allows more in-depth
1940 testing of a configuration. Thanks to Doug MacEachern for the patch.
1941 * collectd-nagios: The Nagios integration command has been updated to
1942 use libcollectdclient. The `percentage' aggregation function has
1943 been added. Thanks to Fabian Linzberger for the patch.

1955 statistics, allowing very detailed name server statistics. Thanks to
1956 Bruno Prémont for this plugin.
1957 * cpu plugin: Report `interrupt' separately when using
1958 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1959 example for native OpenBSD support, has been added. Thanks to Simon
1960 Kuhnle for the patch.
1961 * csv plugin: Make it possible to write values to STDOUT instead of
1962 files. This is meant for testing purposes mostly. The output written
1963 to STDOUT is compatible with the exec plugin. Thanks to Doug
1964 MacEachern for the patch.
1965 * curl plugin: This new plugin can be used to read web pages and parse
1966 them using the same mechanism that's used in the tail plugin.
1967 * dbi plugin: This new plugin allows you to connect to a variety of
1968 relational databases and use SQL to gather custom statistics from
1969 it. It is similar to the already existing PostgreSQL plugin but uses
1970 libdbi to communicate with the database(s).
1971 * interface plugin: Use the ignorelist framework when selecting /
1972 ignoring interfaces. This allows one to use regular expressions to
1973 select interfaces, too.
1974 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1975 Thanks to Bruno Prémont for this patch.
1976 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

1992 allowing plugins to register `matches' and `targets'.
1993 * postgresql plugin: The preferred configuration syntax has been
1994 updated to be in line with the syntax used by the new dbi and oracle
1995 plugins. The compatibility code for the old syntax is present.
1996 Support for the new `Result' blocks and the interval parameter has
1998 * processes plugin: Stacksize and virtual memory usage statistics have
1999 been added. Portability fixes.
2000 * rrdcached plugin: This new plugin uses the (still in development)
2001 RRD accelerator daemon, rrdcached. This daemon works very similar to
2002 the original rrdtool plugin of collectd, but adds some more nice
2004 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2007 2009-05-09, Version 4.5.4
2008 * Build system, various plugins: Many build fixes for FreeBSD,
2009 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern

2021 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2023 * rrdtool plugin: Fix a possible race condition: If the network plugin
2024 is initialized and dispatches a value before the rrdtool plugin is
2025 initialized, the daemon may crash.
2026 * memory plugin: Fix a potential problem under Solaris.
2028 2009-02-22, Version 4.5.3

2038 code. Thanks to "thated" for reporting this.
2040 2009-01-02, Version 4.5.2
2041 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2042 file may be in both locations, especially when the database was
2043 installed in a non-standard path. Thanks to Dusty Doris for
2045 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2046 Solaris, in the configure script automatically.
2047 * build system, tcpconns plugin: Check for `kvm_nlist' and
2048 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2049 library with similar functions to the BSD variant, but doesn't
2050 provide these necessary functions.
2051 * collectd.conf(5): Various fixes and clarifications.
2052 * collectd: Remove a GNUism (unnamed unions), thus improving

2057 * filecount plugin: Fix an off-by-one error. This error may cause a
2059 * network plugin: Fix the handling of `type' in the network protocol.
2060 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2061 much larger buffer. This caused the `type' to be transferred much
2062 more often than necessary. In some cases, e. g. the `cpu' and
2063 `cpufreq' plugins being used at the same time, data may be corrupted
2064 in those files. Thanks to Bruno Prémont for debugging and reporting
2066 * processes plugin: Fix a possible segmentation fault when specifying
2067 invalid configuration options.
2068 * unixsock plugin: Make sure the initialization function is run only
2069 once. This resolves a file descriptor leak under systems which run
2070 the initialization more than once, such as Solaris.
2072 2008-10-16, Version 4.5.1
2073 * build system: Change `--enable-<plugin>' to abort with an error if
2074 dependencies are not met. Thanks to Bruno Prémont for the patch.
2075 Also, the poisoning of various string functions has been restricted
2077 * collectd: Fix a memory leak in the global value cache. With every
2078 *missing* value a couple of bytes would be leaked. Another memory
2079 leak in the configuration handling code has been fixed. Thanks to
2080 Niraj Tolia for reporting these issues.
2081 * collectd: Fix an off-by-one error in the ignorelist functionality.
2082 When using regular expressions, the last character would be missing,
2083 possibly matching differently from what one would expect.
2084 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2086 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2087 Linzberger for reporting the bug.
2088 * iptables plugin: Fix an off-by-one error. If a string was just one
2089 character too long, it was truncated instead of reporting an error.
2090 * network plugin: Fix a memory leak in the configuration handling
2091 code. Thanks to Niraj Tolia for reporting this issue.
2092 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2093 * postgresql plugin: Don't reopen connection during reinitialization.
2094 This fixes a bug under Solaris and potentially other platforms.

2096 leaks. Thanks to ``Admin'' for reporting these bugs.
2097 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2099 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2100 problems with some `libc's. Thanks to Matthias Lay for reporting the

2110 Notifications upon added and removed sensors can now be generated.
2111 * notify_desktop plugin: This new plugin sends notifications to the
2112 X desktop using the structure defined in the `Desktop Notification
2114 * notify_email plugin: This new plugin sends out notifications via
2115 email, using the `esmtp' library.
2116 * onewire plugin: The new experimental(!) onewire plugin reads values,
2117 such as temperatures, from sensors connected to the computer via the
2119 * perl plugin: Improved synchronized access to internal data structures
2120 and fixed a possible dead-lock.
2121 * perl plugin: Added the ability to flush certain identifiers and marked
2122 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2124 * perl plugin: Added the ability to configure Perl plugins.

2132 using Linux ACPI thermal zone data.
2134 2009-01-02, Version 4.4.5
2135 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2136 file may be in both locations, especially when the database was
2137 installed in a non-standard path. Thanks to Dusty Doris for
2139 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2140 Solaris, in the configure script automatically.
2141 * collectd.conf(5): Various fixes and clarifications.

2145 * network plugin: Fix the handling of `type' in the network protocol.
2146 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2147 much larger buffer. This caused the `type' to be transferred much
2148 more often than necessary. In some cases, e. g. the `cpu' and

2316 * collectd: The `Include' config option has been expanded to handle
2317 entire directories and shell wildcards.
2318 * collectdmon: The new `collectdmon' binary detects when collectd
2319 terminates and automatically restarts it again.
2320 * csv plugin: The CSV plugin is now able to store counter values as a
2321 rate, using the `StoreRates' configuration option.
2322 * exec plugin: Handling of notifications has been added and the
2323 ability to pass arguments to the executed programs has been added.
2324 * hddtemp plugin: The new `TranslateDevicename' option lets you
2325 disable the translation from device names to major-minor-numbers.
2326 * logfile plugin: Handling of notifications has been added.
2327 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2328 domain name lookups in this plugin.
2329 * perl plugin: Many internal changes added support for handling multiple
2330 threads making the plugin reasonably usable inside collectd. The API has
2331 been extended to support notifications and export global variables to
2332 Perl plugins; callbacks now have to be identified by name rather than a
2333 pointer to a subroutine. The plugin is no longer experimental.
2334 * uuid plugin: The new UUID plugin sets the hostname to an unique
2335 identifier for this host. This is meant for setups where each client
2336 may migrate to another physical host, possibly going through one or
2337 more name changes in the process. Thanks to Richard Jones from
2338 Red Hat's Emerging Technology group for this plugin.
2339 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2340 CPU, disk and network statistics about guest systems on the same
2341 physical server. Thanks to Richard Jones from Red Hat's Emerging
2342 Technology group for this plugin.
2344 2008-04-22, Version 4.2.7
2345 * build system: Improved detection of several libraries, especially if
2346 they are in non-standard paths.
2347 * build system: Portability fixes: Automatically define "_REENTRANT"
2348 if the libc expects it.
2349 * collectd: Error and warning messages have been improved.
2350 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2352 * apache plugin: Allocate new memory when reading a webpage instead of
2353 using a buffer of static size.
2354 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2356 * hddtemp plugin: Error and warning messages have been improved.
2357 * sensors plugin: Fix sensor collection for some chip types.
2359 2008-03-29, Version 4.2.6
2360 * collectd: Improved error messages when parsing the configuration.
2361 * sensors plugin: Fix temperature collection with libsensors4.
2362 * unixsock plugin: Fix mixed input and output operation on streams.
2363 * wireless plugin: Fix reading noise value.
2365 2008-03-04, Version 4.2.5
2366 * apache plugin: Improved initialization and error messages.
2367 * exec plugin: Set supplementary group IDs.
2369 + Create separate threads for reading from the socket and parsing
2370 and dispatching incoming packets. Versions prior to this may have
2371 problems in high-load situations, where the socket receive buffers
2372 overflows, resulting in gaps in the data.
2373 + Use `memcpy' when constructing/parsing a package to avoid
2374 alignment problems on weird architectures, such as Sparc.
2375 + Translate doubles to/from the x86 byte representation to ensure
2376 cross-platform compatibility.
2377 * ping plugin: Correct the handling of the `TTL' setting.
2378 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2379 * swap plugin: Reapply a patch for Solaris.
2380 * tcpconns plugin: Portability improvements.
2382 2008-01-21, Version 4.2.4
2383 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2384 the permission on the socket as documented in the manpage. Thanks to
2385 Evgeny Chukreev for fixing this issue.
2386 * collectd: The documentation has been improved.
2388 2007-12-28, Version 4.2.3
2389 * sensors plugin: Updated the plugin to build and work with version 3
2390 of the libsensors library.
2392 2007-12-15, Version 4.2.2
2393 * nginx plugin: Incorrect comparison of strings lead to a segfault
2394 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2396 * logfile plugin: The config option `Timestamp' was handled
2397 incorrectly and basically always active. Thanks to Luke Heberling
2400 2007-11-08, Version 4.2.1
2401 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2402 enabled on the host.
2403 * snmp plugin: Fix a memory leak.
2405 2007-10-27, Version 4.2.0
2406 * collectd: The new config option `Include' lets you include other
2407 configfiles and thus split up your config into smaller parts. This
2408 may be especially interesting for the snmp plugin to keep the data
2409 definitions separate from the host definitions.
2410 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2411 (number of connections, octets and packets for each service and
2412 destination). Thanks to Sebastian Harl for this plugin.
2413 * memcached plugin: The new `memcached' plugin connects to a memcached
2414 daemon process and collects statistics of this distributed caching
2415 system. Thanks to Antony Dovgal for contributing this plugin.
2416 * nginx plugin: The new `nginx' plugin reads the status page of an
2417 nginx daemon and saves the handled connections and requests.
2418 * perl plugin: Many changes, including the added `EnableDebugger'
2419 config option which lets you debug your Perl plugins more easily.
2420 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2421 be more thread-safe otherwise by locking calls to the library.
2422 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2423 correct the values returned by SNMP-agents. If a <data> block is
2424 defined as `table' the instance is now optional. The sequence number
2425 is used as the type-instance in this case. The new `InstancePrefix'
2426 option allows to add arbitrary prefixes to the type-instance.
2427 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2428 certain TCP connections and what state they're in. This can be used
2429 to see how many connections your FTP server has to handle or how
2430 many outgoing connections your mailserver has open.
2432 2008-01-11, Version 4.1.6
2433 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2434 the permission on the socket as documented in the manpage. Thanks to
2435 Evgeny Chukreev for fixing this issue.
2436 * collectd: The documentation has been improved.
2438 2007-12-27, Version 4.1.5
2439 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
2441 * sensors plugin: Updated the plugin to build and work with version 3
2442 of the libsensors library.
2444 2007-11-08, Version 4.1.4
2445 * Build system: Improve detection of the rrd library, especially if
2446 it's in a non-standard location.
2447 * Build system: A bug when parsing the argument for
2448 `--with-libnetsnmp' has been fixed.
2449 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2450 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2451 a deadlock or delay when shutting down the daemon.
2452 * snmp plugin: Fix a memory leak.
2454 2007-10-24, Version 4.1.3
2455 * collectd: A build issue under Solaris has been resolved by renaming
2457 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2458 be more thread-safe otherwise by locking calls to the library.
2460 2007-09-28, Version 4.1.2
2461 * apcups plugin: Fix reporting of the `load percent' data.
2462 * wireless plugin: Correct the handling of cards returning signal and
2463 noise quality as percentage.
2464 * perl plugin: Fix a possible buffer overflow in get_module_name().
2465 * build system: Further improve the detection of libraries.
2466 * netlink plugin: Build issues under some older versions of the Linux
2467 includes (i. e. Debian Sarge) have been fixed.
2468 * snmp plugin: Fix a potential segfault when a host times out. Add
2469 support for the `timeticks' type.
2471 2007-09-12, Version 4.1.1
2472 * Build system: The detection of `libnetlink' has been improved.
2473 * collectd: The documentation has been fixed in numerous places.
2474 * exec plugin: Setting the group under which to run a program has been
2476 * collectd: The `sstrerror' function was improved to work correctly
2477 with the broken GNU version of `strerror_r'.
2478 * collectd: Write an error message to STDERR when loading of a plugin
2480 * apcups plugin: Fix the `types' used to submit the values: They still
2481 has an `apcups_' prefix which doesn't work anymore.
2482 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2483 whatever the client thinks is `now'..
2485 2007-09-01, Version 4.1.0
2486 * Build system: The build system has been changed to automatically
2487 disable all plugins, which are missing dependencies. The dependency
2488 checking has been removed from the plugins themselves to remove
2490 * Flexible interval: The interval of collected data is now sent along
2491 with the data itself over the network, so that the interval-settings
2492 of server and clients no longer needs to match.
2493 * netlink plugin: The new `netlink' plugin connects to the Linux
2494 kernel using a netlink socket and uses it to query information about
2495 interfaces, qdiscs and classes.
2496 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2497 to not block data collection.
2498 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2499 network devices, such as switches, routers, thermometers, rack
2500 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2502 * unixsock plugin: Added the `LISTVAL' command.
2503 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2504 of music played with xmms.
2506 2007-09-28, Version 4.0.9
2507 * apcups plugin: Fix reporting of the `load percent' data.
2508 * wireless plugin: Correct the handling of cards returning signal and
2509 noise quality as percentage.
2510 * perl plugin: Fix a possible buffer overflow in get_module_name().
2512 2007-09-12, Version 4.0.8
2513 * collectd: The `sstrerror' function was improved to work correctly
2514 with the broken GNU version of `strerror_r'.
2515 * collectd: Write an error message to STDERR when loading of a plugin
2517 * apcups plugin: Fix the `types' used to submit the values: They still
2518 has an `apcups_' prefix which doesn't work anymore.
2519 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2520 whatever the client thinks is `now'..
2522 2007-08-26, Version 4.0.7
2523 * documentation: Some typos have been fixed and some information has
2525 * build system: Many fixes for detecting libraries in unusual places,
2526 such as on RedHat systems. The affected libraries are `libcurl',
2527 `libmysql', and `libupsclient'.
2528 * network plugin: Allow the `Port' option to be specified as a number
2529 (i. e. without quotes).
2530 * nut plugin: A fix allows linking the nut plugin against
2531 libupsclient, version >= 2.2.0.
2532 * processes plugin: Fix a potential segmentation fault.
2534 2007-07-30, Version 4.0.6
2535 * sensors plugin: Fix the ignorelist functionality: Only the `type
2536 instance' was used to match against the list, but the documentation
2537 told otherwise. This release fixes the code, so it complies with the
2539 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2540 configuration messages will end up in the logging facility.
2541 * conrtib/fedora: The contributed specfile for Fedora has been
2544 2007-07-05, Version 4.0.5
2545 * Portability: More fixes for OpenBSD have been included.
2547 2007-06-24, Version 4.0.4
2548 * cpu plugin: Fixed the Solaris code.
2549 * dns plugin: Fixed a build issue for OpenBSD.
2550 * interface plugin: Fixed the Solaris code.
2551 * load plugin: Fixed the alternative `/proc' Linux code.
2552 * memory plugin: Fixed the Solaris code.
2553 * oconfig: Don't require `-lfl' anymore.
2555 2007-06-19, Version 4.0.3
2556 * cpu plugin: Fix the Darwin / Mac OS X code.
2557 * ping plugin: Use the return value of `getpid', not its address.
2558 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2559 initialized correctly.
2560 * configure: Added `--with-nan-emulation' to aid cross compilation.
2562 2007-06-12, Version 4.0.2
2563 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2564 they're given in numerically form.
2566 2007-06-07, Version 4.0.1
2567 * iptables plugin: A bug in the configuration routine has been fixed.
2568 Setting a comment in the configfile will no longer cause a
2571 2007-06-03, Version 4.0.0
2572 * collectd: The plugin-infrastructure has been changed to allow for
2573 more types of plugins, namely `write' and `log' plugins.
2574 * collectd: The read-function has been changed to read many plugins in
2575 parallel, using threads. Thus, plugins generally need to use
2576 thread-safe functions from now on.
2577 * collectd: The '-t' command line options allows to perform syntax tests
2578 of the configuration file and exit immediately.
2579 * csv plugin: The new `csv' plugin handles output to `comma separated
2581 * rrdtool plugin: The new `rrdtool' plugin handles output to
2582 RRD-files. Data can be cached to combine multiple updates into one
2583 write to increase IO-performance.
2584 * network plugin: The new `network' plugin handles IO via the network.
2585 It implements a different, much more extensible protocol which can
2586 combine many values in one packet, decreasing the number of UDP-
2587 packets being sent. It can read from and send to the network and
2588 with the appropriate configuration even forward packets to other
2590 * unixsock plugin: The new `unixsock' plugin provides an interface to
2591 communicate with the daemon while it is running. Right now the
2592 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2594 * perl plugin: The new `perl' plugin allows you to write extensions
2595 for collectd in the scripting-language Perl.
2596 * logfile plugin: The new `logfile' plugin writes logmessages to files
2597 or STDOUT or STDERR.
2598 * syslog plugin: The new `syslog' plugin sends logmessages to the
2599 system's syslog daemon.
2600 * entropy plugin: The new `entropy' plugin collects the amount of
2601 entropy currently being available to the system.
2602 * exec plugin: The new `exec' plugin forks child processes and reads
2603 back values provided by the forked processes.
2604 * iptables plugin: The new `iptables' plugin reads counters from
2605 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2607 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2608 to Peter Holik for contributing this plugin.
2609 * nut plugin: The new `nut' plugin connects the upsd of the `network
2610 ups tools' and reads information about the connected UPS.
2611 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2612 connections) field was added by Florent Monbillard.
2613 * collectd-nagios: The new `collectd-nagios' binary queries values
2614 from collectd, parses them and exits according to Nagios-standards.
2615 * manpages: The manpages have been improved a lot.
2617 2007-09-28, Version 3.11.7
2618 * wireless plugin: Correct the handling of cards returning signal and
2619 noise quality as percentage.
2621 2007-08-31, Version 3.11.6
2622 * processes plugin: Fix a potential segmentation fault.
2624 2007-05-29, Version 3.11.5
2625 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2626 * ntpd plugin: Fix a potential buffer overflow.
2627 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2628 were accounted as `zombies'.
2630 2007-04-10, Version 3.11.4
2631 * dns plugin: Change the order of includes to make the plugin compile
2634 2007-03-30, Version 3.11.3
2635 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2636 of the unused `COLLECT_KSTAT'.
2638 2007-02-11, Version 3.11.2
2639 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2640 NULL-pointer may have been passed to `printf' which causes a
2641 segfault with some libcs.
2643 2007-02-10, Version 3.11.1
2644 * df plugin: Some wrong defines have been fixed so the plugin works
2645 under Solaris again.
2646 * dns plugin: The usage of a struct has been fixed to work with
2648 * processes plugin: Some missing defines have been added so the plugin
2649 compiles cleanly under FreeBSD and presumably other UNIXes.
2651 2006-12-22, Version 3.11.0
2652 * collectd: The new command line option `-P' makes it easier for
2653 distributors to change the location of PID-files.
2654 * collectd: The daemon shuts down faster now which makes it easier to
2655 write init.d-scripts for it.
2656 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2657 caused problems every now and then.
2658 * df plugin: New config options allow to ignore certain mountpoints,
2659 filesystem types or devices.
2660 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2661 and interprets it. It collects traffic as well as qtype, opcode and
2663 * email plugin: Sebastian Harl has contributed this plugin which
2664 counts received mails in categories (e. g. ham, spam, virus), spam
2665 score (as given by SpamAssassin) and check types.
2666 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2667 uses `mbmon' to gather information from sensors on the motherboard.
2668 * processes plugin: Collect detailed statistics for configured
2669 processes, that's process and thread count, CPU usage, resident
2670 segment size and pagefaults.
2671 * multimeter plugin: Peter Holik contributed a new plugin which
2672 queries multimeters.
2673 * sensors plugin: Lubos Stanek has put much effort into improving this
2674 plugin, including `extended naming', collection of voltage values
2675 and the possibility to ignore certain values.
2677 2006-12-21, Version 3.10.4
2678 * Max Kellermann has identified a bug in the server routine: When
2679 opening a socket fails the daemon will (re)try opening the socket in
2680 an endless loop, ultimately leading to a `EMFILE' error.
2682 2006-11-04, Version 3.10.3
2683 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2684 ntpd's reply was sent in more than one packet, the buffer size was
2685 calculated incorrectly, resulting in the reading of uninitialized or
2688 2006-11-01, Version 3.10.2
2689 * The sample config file has been improved.
2690 * Errors in the manpages have been corrected.
2691 * The ping-plugin now adds hosts during initialization, not during
2692 startup. This speeds up startup when no network connectivity is
2693 available. Also, the hosts are being added later when the network is
2695 * Improved BSD-support for the df-plugin.
2696 * Fixed syntax errors in the swap-plugin for Mac OS X.
2697 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2699 * Don't disable the mysql-plugin if connecting to the database fails
2700 during initialization. Instead, try again in increasing intervals.
2702 2006-07-19, Version 3.10.1
2703 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2704 the apcups cannot be reached, unconnected sockets will pile up and
2705 eventually lead to `Too many open files' errors.
2707 2006-07-09, Version 3.10.0
2708 * The `disk' plugin has been ported to Darwin.
2709 * The `battery' plugin should work on many Apple computers now.
2710 * The `traffic' plugin can now ignore certain interfaces. Also,
2711 statistics for sent/received packets and errors have been added.
2712 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2713 to Anthony Gialluca for contributing this plugin and providing me
2714 with a test environment :)
2715 * A plugin for monitoring an NTP instance and the local clock drift
2718 2006-06-25, Version 3.9.4
2719 * The Solaris code in the `swap' plugin has been changed to reflect
2720 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2722 * The debugging system has been fixed to work with the Sun libc.
2723 * When built without librrd the variable `operating_mode' could be
2724 uninitialized. Thanks to David Elliot for reporting the bug.
2726 2006-06-01, Version 3.9.3
2727 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2728 operating systems also profit from the changes, but I wasn't able to
2730 * Changed the build system to find the netinet-includes under FreeBSD
2731 and therefore successfully build the `liboping' library there.
2733 2006-05-09, Version 3.9.2
2734 * Applied a patch to the `liboping' library. Due to a bug in the
2735 sequence checking the `ping' plugin stopped working after
2736 approximately 7.6 days.
2738 2006-05-09, Version 3.8.5
2739 * Applied a patch to the `liboping' library. Due to a bug in the
2740 sequence checking the `ping' plugin stopped working after
2741 approximately 7.6 days.
2743 2006-04-21, Version 3.9.1
2744 * Build issues with Solaris and possible other architectures have been
2746 * Problems when building the `apache'-plugin without `libcurl' have
2748 * A bug in the `ping' plugin has been fixed. Sorry folks.
2750 2006-04-02, Version 3.9.0
2751 * A plugin to monitor the Apache webserver has been added.
2752 <http://httpd.apache.org/>
2753 * A plugin to collect statistics about virtual servers using VServer.
2754 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2756 * A plugin for wireless LAN cards has been added. It monitors signal
2757 strength, link quality and noise ratio..
2758 * A plugin for Apple hardware sensors has been added.
2759 * An option to compile collectd with different `step' and `heartbeat'
2760 settings has been added. The size of RRAs is no longer static but
2761 calculated based on the settings for `step' and `width'.
2762 * The `ping' plugin can now be configured to use a certain TTL.
2763 * A plugin to monitor the hardware sensors of Apple computers has been
2765 * The plugins `cpu', `memory', `processes' and `traffic' have been
2766 ported to Mach/Darwin (Mac OS X).
2767 * The `log mode' has been contributed by Christophe Kalt. It writes
2768 the data into text files rather than RRD files.
2770 2006-04-09, Version 3.8.4
2771 * Applied patch by Vincent Stehlé which improves the disk-name
2772 resolution in the `hddtemp' plugin for Linux systems.
2774 2006-04-02, Version 3.8.3
2775 * Applied a patch by James Byers: The MySQL plugin was not working
2776 with MySQL 5.0.2 or later.
2778 2006-03-14, Version 3.8.2
2779 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2780 the GNU libc, because it points to `/etc/fstab' rather than
2783 2006-03-13, Version 3.8.1
2784 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2785 * Fixes in the debian `postinst' and `init.d' scripts.
2787 2006-03-09, Version 3.8.0
2788 * The `ping' plugin no longer uses `libping' but a self written
2789 library named `liboping'. With this library it's possible to ping
2790 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2792 2006-02-18, Version 3.7.2
2793 * A simple bug in the `battery' plugin has been fixed. It should now
2794 work with ACPI based batteries as well. Thanks to Sebastian for
2796 * Fixing a bug that prevented collectd to be built without librrd.
2797 Thanks to Werner Heuser for reporting it.
2799 2006-02-04, Version 3.7.1
2800 * The new network code has been improved to build with older versions
2802 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2803 to Tommie Gannert for this patch.
2805 2006-01-30, Version 3.7.0
2806 * The `battery' plugin has been added. It collects information about
2808 * The MySQL plugin has been improved: It now writes two more RRD
2809 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2810 * The `cpufreq' plugin now reads another file since the file it did
2811 read so far causes much overhead in the kernel. Also, you need root
2812 to read the old file, but not to read the new one.
2813 * The `hddtemp' plugin can now be configured to connect to another
2814 address and/or port than localhost.
2815 * The `df' plugin now prefers `statvfs' over `statfs'.
2816 * The network code has been rewritten. collectd now supports unicast
2817 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2818 be set in the configfile.
2820 2006-01-24, Version 3.6.2
2821 * Due to a bug in the configfile handling collectd wouldn't start in
2822 client mode. This released fixes this.
2824 2006-01-20, Version 3.6.1
2825 * Due to a bug in `configure.in' all modules and the binary were
2826 linked against `libmysqlclient'. This issue is solved by this
2829 2006-01-17, Version 3.6.0
2830 * A config file has been added. This allows for loading only specific
2832 * A `df' plugin has been added.
2833 * A `mysql' plugin has been added.
2834 * The `ping' plugin doesn't entirely give up hope when a socket error
2835 occurred, but will back of and increase the intervals between tries.
2837 2006-01-21, Version 3.5.2
2838 * Fixed yet another bug in the signal handling.. Stupid typo..
2839 * Improved the ping plugin to not give up on socket errors (backport
2842 2005-12-18, Version 3.5.1
2843 * The PID-file is now deleted correctly when shutting down the daemon.
2844 * SIGINT and SIGTERM are now handled correctly.
2846 2005-12-16, Version 3.5.0 (Revision 326)
2847 * A bug in the `load' module under Solaris has been fixed.
2848 * The `users' module has been contributed by Sebastian Harl. It counts
2849 currently logged in users.
2850 * The CPU module now works under FreeBSD without the use of
2851 `libstatgrab', however SMP support is missing.
2852 * The default directories for the RRD files and the PID file now
2853 depend on the compile time setting of `localstatedir'.
2855 2005-11-15, Version 3.4.0 (Revision 236)
2856 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2857 from gentoo's bugzilla for writing the patch.
2858 * The build dependency for librrd has been removed. Binaries built
2859 without librrd are client-only and will multicast their value as
2860 with the `-c' argument.
2861 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2862 * The newly introduced `-f' switch prevents daemon initialization
2863 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2864 Barcellos for this patch.
2866 2005-11-04, Version 3.3.0 (Revision 216)
2867 * New modules have been added:
2868 - `serial', for monitoring traffic on the serial interfaces
2869 - `nfs', for graphing NFS procedure calls
2870 - `tape', traffic from/to tape devices
2871 * The memory.rrd now accepts more than 4Gig of memory.
2873 2005-10-26, Version 3.2.0 (Revision 200)
2874 * Support for graphing the processes has been added (thanks to Lyonel
2876 * If reading from hddtemp fails collectd will increase the time
2877 between polls up to one day.
2878 * The init.d files have been improved.
2879 * Problems with the spec file have been fixed.
2881 2005-10-16, Version 3.1.0 (Revision 194)
2882 * Added the `setsid' syscall to the startup code.
2883 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2885 2005-09-30, Version 3.0.0 (Revision 184)
2886 * The ability to send/receive data to/from the network (think
2887 multicast) has been added.
2888 * Modules have been split up into shared libraries can be loaded at
2889 runtime. The biggest advantage is that the core program doesn't need
2890 to be linked against an external library.
2891 * A patch by George Kargiotakis has been applied: It fixes the sensors
2892 behaviour then more than one sensor is being queried.
2894 2005-09-16, Version 2.1.0 (Revision 172)
2895 * A module for swap statistics has been added.
2897 2005-09-09, Version 2.0.0 (Revision 135)
2898 * Filenames can no longer be configured at program startup. The only
2899 options as of this version are the directory and ping hosts.
2900 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2901 Soft-IRQ statistics are added to `System'.
2902 * Diskstats now collect read and write bytes, not sectors.
2903 * Ping statistics can now be collected for more than one host. There
2904 is no default any more: If no host is given no host will be pinged.
2905 * A self-written patch for libping has been applied so it builds
2908 2005-09-01, Version 1.8.1 (Revision 123)
2909 * Much improved configure-script: libraries and features may now be
2911 * More detailed warnings/error messages when RRD update fails.
2913 2005-08-29, Version 1.8.0:
2914 * Support for collecting disk statistics under Solaris.
2916 2005-08-25, Version 1.7.0:
2917 * Support for libstatgrab[1] for load, memory usage and network
2918 traffic. CPU- and disk-usage are not (yet) supported, since
2919 libstatgrab returns insufficient information. I will contact the
2921 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2922 aren't necessarily counted linear which is now handled correctly.
2923 [1]: http://www.i-scream.org/libstatgrab/
2925 2005-08-21, Version 1.6.0:
2926 * Basic support for Solaris: System load and cpu-usage can be
2927 collected under Solaris, too. Other stats will follow later.
2928 * Many fixes in the autoconf-script
2929 * Collection/Museum scripts have been added under contrib/museum
2930 * collectd may now be started in unprivileged mode, though ping
2931 statistics will not work.
2933 2005-07-17, Version 1.5.1:
2934 * Diskstats-RRDs now use major/minor for naming. Some systems have
2935 weird strings as disk-names..
2937 2005-07-17, Version 1.5:
2938 * A new module, diskstats, has been added. It collects information
2939 about the disks and partitions.
2941 2005-07-11, Version 1.4.2:
2942 * The meminfo module has been changed to work with more platforms
2943 and/or kernel versions.
2945 2005-07-10, Version 1.4.1: Correct traffic stats
2946 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2947 forgot to correct when I changed that module.
2949 2005-07-09, Version 1.4: More traffic stats
2950 * Traffic is now collected for all interfaces that can be found
2951 * Temperature-statistics are read from lm-sensors if available
2953 2005-07-08, Version 1.3: CPU stats
2954 * Collecting CPU statistics now
2956 2005-07-12, Version 1.2: Using syslog
2957 * collectd is now using the syslog facility to report errors, warnings
2959 * The default directory is now /var/db/collectd
2961 2005-07-10, Version 1.1: Minor changes
2962 * Nothing really useful to say ;)
2964 2005-07-09, Version 1.0: Initial Version
2965 * The following modules are provided:
