1964 name which prevented this match to be used as documented. Thanks to
1965 Bruno Prémont for finding this problem.
1966 * bind plugin: Fix collection of the cached RR sets. The number of RR
1967 sets currently in the cache was collected as a counter value, which
1968 is nonsense. Thanks to Bruno Prémont for implementing this.
1969 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1970 primarily BSDs, don't take it well and crash.
1971 * oracle plugin: Portability to 64 bit systems has been improved.
1972 * postgresql plugin: The default configuration has been improved.
1973 * rrdtool plugin: Fix a possible race condition: If the network plugin

2010 Kuhnle for the patch.
2011 * csv plugin: Make it possible to write values to STDOUT instead of
2012 files. This is meant for testing purposes mostly. The output written
2013 to STDOUT is compatible with the exec plugin. Thanks to Doug
2014 MacEachern for the patch.
2015 * curl plugin: This new plugin can be used to read web pages and parse
2016 them using the same mechanism that's used in the tail plugin.
2017 * dbi plugin: This new plugin allows you to connect to a variety of
2018 relational databases and use SQL to gather custom statistics from
2019 it. It is similar to the already existing PostgreSQL plugin but uses
2020 libdbi to communicate with the database(s).
2021 * interface plugin: Use the ignorelist framework when selecting /
2022 ignoring interfaces. This allows one to use regular expressions to
2023 select interfaces, too.

2048 * processes plugin: Stacksize and virtual memory usage statistics have
2049 been added. Portability fixes.
2050 * rrdcached plugin: This new plugin uses the (still in development)
2051 RRD accelerator daemon, rrdcached. This daemon works very similar to
2052 the original rrdtool plugin of collectd, but adds some more nice

2090 2009-01-02, Version 4.5.2
2091 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2092 file may be in both locations, especially when the database was
2093 installed in a non-standard path. Thanks to Dusty Doris for
2095 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2096 Solaris, in the configure script automatically.
2097 * build system, tcpconns plugin: Check for `kvm_nlist' and
2098 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2099 library with similar functions to the BSD variant, but doesn't
2100 provide these necessary functions.

2109 * network plugin: Fix the handling of `type' in the network protocol.
2110 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2111 much larger buffer. This caused the `type' to be transferred much
2112 more often than necessary. In some cases, e. g. the `cpu' and
2113 `cpufreq' plugins being used at the same time, data may be corrupted
2114 in those files. Thanks to Bruno Prémont for debugging and reporting
2116 * processes plugin: Fix a possible segmentation fault when specifying
2117 invalid configuration options.
2118 * unixsock plugin: Make sure the initialization function is run only
2119 once. This resolves a file descriptor leak under systems which run
2120 the initialization more than once, such as Solaris.
2122 2008-10-16, Version 4.5.1
2123 * build system: Change `--enable-<plugin>' to abort with an error if
2124 dependencies are not met. Thanks to Bruno Prémont for the patch.
2125 Also, the poisoning of various string functions has been restricted
2127 * collectd: Fix a memory leak in the global value cache. With every
2128 *missing* value a couple of bytes would be leaked. Another memory
2129 leak in the configuration handling code has been fixed. Thanks to
2130 Niraj Tolia for reporting these issues.
2131 * collectd: Fix an off-by-one error in the ignorelist functionality.
2132 When using regular expressions, the last character would be missing,
2133 possibly matching differently from what one would expect.
2134 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2136 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2137 Linzberger for reporting the bug.
2138 * iptables plugin: Fix an off-by-one error. If a string was just one
2139 character too long, it was truncated instead of reporting an error.

2146 leaks. Thanks to ``Admin'' for reporting these bugs.
2147 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2149 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes

2164 * notify_email plugin: This new plugin sends out notifications via
2165 email, using the `esmtp' library.
2166 * onewire plugin: The new experimental(!) onewire plugin reads values,
2167 such as temperatures, from sensors connected to the computer via the
2169 * perl plugin: Improved synchronized access to internal data structures
2170 and fixed a possible dead-lock.
2171 * perl plugin: Added the ability to flush certain identifiers and marked
2172 plugin_flush_all() and plugin_flush_one() as deprecated in favor of

2195 * network plugin: Fix the handling of `type' in the network protocol.
2196 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2197 much larger buffer. This caused the `type' to be transferred much
2198 more often than necessary. In some cases, e. g. the `cpu' and

2311 * network plugin: A fix in the initialization function solves problems
2313 * nginx plugin: A thread-unsafe function has been replaced.
2314 * vserver plugin: A thread-unsafe function has been replaced.
2315 * wireless plugin: A work-around for broken wireless drivers has been
2318 2008-04-22, Version 4.3.3
2319 * build system: Improved detection of several libraries, especially if
2320 they are in non-standard paths.
2321 * build system: Portability fixes: Automatically define "_REENTRANT"
2322 if the libc expects it.
2323 * collectd: Error and warning messages have been improved.
2324 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2326 * apache plugin: Allocate new memory when reading a webpage instead of
2327 using a buffer of static size.
2328 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2330 * hddtemp plugin: Error and warning messages have been improved.
2331 * sensors plugin: Fix sensor collection for some chip types.
2333 2008-03-29, Version 4.3.2
2334 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2335 `Persist' threshold options.
2336 * collectd: Fix handling of missing values in the global value cache.
2337 * collectd: Improved error messages when parsing the configuration.
2338 * sensors plugin: Fix temperature collection with libsensors4.
2339 * unixsock plugin: Fix mixed input and output operation on streams.
2340 * wireless plugin: Fix reading noise value.
2342 2008-03-05, Version 4.3.1
2343 * exec plugin: Set supplementary group IDs.
2345 + Use `memcpy' when constructing/parsing a package to avoid
2346 alignment problems on weird architectures, such as Sparc.
2347 + Translate doubles to/from the x86 byte representation to ensure
2348 cross-platform compatibility.
2349 * ping plugin: Correct the handling of the `TTL' setting.
2350 * swap plugin: Reapply a patch for Solaris.
2351 * tcpconns plugin: Portability improvements.
2353 2008-02-18, Version 4.3.0
2354 * collectd: Notifications have been added to the daemon. Notifications
2355 are status messages that may be associated with a data instance.
2356 * collectd: Threshold checking has been added to the daemon. This
2357 means that you can configure threshold values for each data
2358 instance. If this threshold is exceeded a notification will be
2360 * collectd: The new `FQDNLookup' option tells the daemon to use the
2361 full qualified domain name as the hostname, not just the host part
2362 es returned by `gethostname(2)'.
2363 * collectd: Support for more than one `TypesDB' file has been added.
2364 This is useful when one such file is included in a package but one
2365 wants to add custom type definitions.
2366 * collectd: The `Include' config option has been expanded to handle
2367 entire directories and shell wildcards.
2368 * collectdmon: The new `collectdmon' binary detects when collectd
2369 terminates and automatically restarts it again.
2370 * csv plugin: The CSV plugin is now able to store counter values as a
2371 rate, using the `StoreRates' configuration option.
2372 * exec plugin: Handling of notifications has been added and the
2373 ability to pass arguments to the executed programs has been added.
2374 * hddtemp plugin: The new `TranslateDevicename' option lets you
2375 disable the translation from device names to major-minor-numbers.
2376 * logfile plugin: Handling of notifications has been added.
2377 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2378 domain name lookups in this plugin.
2379 * perl plugin: Many internal changes added support for handling multiple
2380 threads making the plugin reasonably usable inside collectd. The API has
2381 been extended to support notifications and export global variables to
2382 Perl plugins; callbacks now have to be identified by name rather than a
2383 pointer to a subroutine. The plugin is no longer experimental.
2384 * uuid plugin: The new UUID plugin sets the hostname to an unique
2385 identifier for this host. This is meant for setups where each client
2386 may migrate to another physical host, possibly going through one or
2387 more name changes in the process. Thanks to Richard Jones from
2388 Red Hat's Emerging Technology group for this plugin.
2389 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2390 CPU, disk and network statistics about guest systems on the same
2391 physical server. Thanks to Richard Jones from Red Hat's Emerging
2392 Technology group for this plugin.
2394 2008-04-22, Version 4.2.7
2395 * build system: Improved detection of several libraries, especially if
2396 they are in non-standard paths.
2397 * build system: Portability fixes: Automatically define "_REENTRANT"
2398 if the libc expects it.
2399 * collectd: Error and warning messages have been improved.
2400 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2402 * apache plugin: Allocate new memory when reading a webpage instead of
2403 using a buffer of static size.
2404 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2406 * hddtemp plugin: Error and warning messages have been improved.
2407 * sensors plugin: Fix sensor collection for some chip types.
2409 2008-03-29, Version 4.2.6
2410 * collectd: Improved error messages when parsing the configuration.
2411 * sensors plugin: Fix temperature collection with libsensors4.
2412 * unixsock plugin: Fix mixed input and output operation on streams.
2413 * wireless plugin: Fix reading noise value.
2415 2008-03-04, Version 4.2.5
2416 * apache plugin: Improved initialization and error messages.
2417 * exec plugin: Set supplementary group IDs.
2419 + Create separate threads for reading from the socket and parsing
2420 and dispatching incoming packets. Versions prior to this may have
2421 problems in high-load situations, where the socket receive buffers
2422 overflows, resulting in gaps in the data.
2423 + Use `memcpy' when constructing/parsing a package to avoid
2424 alignment problems on weird architectures, such as Sparc.
2425 + Translate doubles to/from the x86 byte representation to ensure
2426 cross-platform compatibility.
2427 * ping plugin: Correct the handling of the `TTL' setting.
2428 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2429 * swap plugin: Reapply a patch for Solaris.
2430 * tcpconns plugin: Portability improvements.
2432 2008-01-21, Version 4.2.4
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 2007-12-28, Version 4.2.3
2439 * sensors plugin: Updated the plugin to build and work with version 3
2440 of the libsensors library.
2442 2007-12-15, Version 4.2.2
2443 * nginx plugin: Incorrect comparison of strings lead to a segfault
2444 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2446 * logfile plugin: The config option `Timestamp' was handled
2447 incorrectly and basically always active. Thanks to Luke Heberling
2450 2007-11-08, Version 4.2.1
2451 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2452 enabled on the host.
2453 * snmp plugin: Fix a memory leak.
2455 2007-10-27, Version 4.2.0
2456 * collectd: The new config option `Include' lets you include other
2457 configfiles and thus split up your config into smaller parts. This
2458 may be especially interesting for the snmp plugin to keep the data
2459 definitions separate from the host definitions.
2460 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2461 (number of connections, octets and packets for each service and
2462 destination). Thanks to Sebastian Harl for this plugin.
2463 * memcached plugin: The new `memcached' plugin connects to a memcached
2464 daemon process and collects statistics of this distributed caching
2465 system. Thanks to Antony Dovgal for contributing this plugin.
2466 * nginx plugin: The new `nginx' plugin reads the status page of an
2467 nginx daemon and saves the handled connections and requests.
2468 * perl plugin: Many changes, including the added `EnableDebugger'
2469 config option which lets you debug your Perl plugins more easily.
2470 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2471 be more thread-safe otherwise by locking calls to the library.
2472 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2473 correct the values returned by SNMP-agents. If a <data> block is
2474 defined as `table' the instance is now optional. The sequence number
2475 is used as the type-instance in this case. The new `InstancePrefix'
2476 option allows to add arbitrary prefixes to the type-instance.
2477 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2478 certain TCP connections and what state they're in. This can be used
2479 to see how many connections your FTP server has to handle or how
2480 many outgoing connections your mailserver has open.
2482 2008-01-11, Version 4.1.6
2483 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2484 the permission on the socket as documented in the manpage. Thanks to
2485 Evgeny Chukreev for fixing this issue.
2486 * collectd: The documentation has been improved.
2488 2007-12-27, Version 4.1.5
2489 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
2491 * sensors plugin: Updated the plugin to build and work with version 3
2492 of the libsensors library.
2494 2007-11-08, Version 4.1.4
2495 * Build system: Improve detection of the rrd library, especially if
2496 it's in a non-standard location.
2497 * Build system: A bug when parsing the argument for
2498 `--with-libnetsnmp' has been fixed.
2499 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2500 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2501 a deadlock or delay when shutting down the daemon.
2502 * snmp plugin: Fix a memory leak.
2504 2007-10-24, Version 4.1.3
2505 * collectd: A build issue under Solaris has been resolved by renaming
2507 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2508 be more thread-safe otherwise by locking calls to the library.
2510 2007-09-28, Version 4.1.2
2511 * apcups plugin: Fix reporting of the `load percent' data.
2512 * wireless plugin: Correct the handling of cards returning signal and
2513 noise quality as percentage.
2514 * perl plugin: Fix a possible buffer overflow in get_module_name().
2515 * build system: Further improve the detection of libraries.
2516 * netlink plugin: Build issues under some older versions of the Linux
2517 includes (i. e. Debian Sarge) have been fixed.
2518 * snmp plugin: Fix a potential segfault when a host times out. Add
2519 support for the `timeticks' type.
2521 2007-09-12, Version 4.1.1
2522 * Build system: The detection of `libnetlink' has been improved.
2523 * collectd: The documentation has been fixed in numerous places.
2524 * exec plugin: Setting the group under which to run a program has been
2526 * collectd: The `sstrerror' function was improved to work correctly
2527 with the broken GNU version of `strerror_r'.
2528 * collectd: Write an error message to STDERR when loading of a plugin
2530 * apcups plugin: Fix the `types' used to submit the values: They still
2531 has an `apcups_' prefix which doesn't work anymore.
2532 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2533 whatever the client thinks is `now'..
2535 2007-09-01, Version 4.1.0
2536 * Build system: The build system has been changed to automatically
2537 disable all plugins, which are missing dependencies. The dependency
2538 checking has been removed from the plugins themselves to remove
2540 * Flexible interval: The interval of collected data is now sent along
2541 with the data itself over the network, so that the interval-settings
2542 of server and clients no longer needs to match.
2543 * netlink plugin: The new `netlink' plugin connects to the Linux
2544 kernel using a netlink socket and uses it to query information about
2545 interfaces, qdiscs and classes.
2546 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2547 to not block data collection.
2548 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2549 network devices, such as switches, routers, thermometers, rack
2550 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2552 * unixsock plugin: Added the `LISTVAL' command.
2553 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2554 of music played with xmms.
2556 2007-09-28, Version 4.0.9
2557 * apcups plugin: Fix reporting of the `load percent' data.
2558 * wireless plugin: Correct the handling of cards returning signal and
2559 noise quality as percentage.
2560 * perl plugin: Fix a possible buffer overflow in get_module_name().
2562 2007-09-12, Version 4.0.8
2563 * collectd: The `sstrerror' function was improved to work correctly
2564 with the broken GNU version of `strerror_r'.
2565 * collectd: Write an error message to STDERR when loading of a plugin
2567 * apcups plugin: Fix the `types' used to submit the values: They still
2568 has an `apcups_' prefix which doesn't work anymore.
2569 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2570 whatever the client thinks is `now'..
2572 2007-08-26, Version 4.0.7
2573 * documentation: Some typos have been fixed and some information has
2575 * build system: Many fixes for detecting libraries in unusual places,
2576 such as on RedHat systems. The affected libraries are `libcurl',
2577 `libmysql', and `libupsclient'.
2578 * network plugin: Allow the `Port' option to be specified as a number
2579 (i. e. without quotes).
2580 * nut plugin: A fix allows linking the nut plugin against
2581 libupsclient, version >= 2.2.0.
2582 * processes plugin: Fix a potential segmentation fault.
2584 2007-07-30, Version 4.0.6
2585 * sensors plugin: Fix the ignorelist functionality: Only the `type
2586 instance' was used to match against the list, but the documentation
2587 told otherwise. This release fixes the code, so it complies with the
2589 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2590 configuration messages will end up in the logging facility.
2591 * conrtib/fedora: The contributed specfile for Fedora has been
2594 2007-07-05, Version 4.0.5
2595 * Portability: More fixes for OpenBSD have been included.
2597 2007-06-24, Version 4.0.4
2598 * cpu plugin: Fixed the Solaris code.
2599 * dns plugin: Fixed a build issue for OpenBSD.
2600 * interface plugin: Fixed the Solaris code.
2601 * load plugin: Fixed the alternative `/proc' Linux code.
2602 * memory plugin: Fixed the Solaris code.
2603 * oconfig: Don't require `-lfl' anymore.
2605 2007-06-19, Version 4.0.3
2606 * cpu plugin: Fix the Darwin / Mac OS X code.
2607 * ping plugin: Use the return value of `getpid', not its address.
2608 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2609 initialized correctly.
2610 * configure: Added `--with-nan-emulation' to aid cross compilation.
2612 2007-06-12, Version 4.0.2
2613 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2614 they're given in numerically form.
2616 2007-06-07, Version 4.0.1
2617 * iptables plugin: A bug in the configuration routine has been fixed.
2618 Setting a comment in the configfile will no longer cause a
2621 2007-06-03, Version 4.0.0
2622 * collectd: The plugin-infrastructure has been changed to allow for
2623 more types of plugins, namely `write' and `log' plugins.
2624 * collectd: The read-function has been changed to read many plugins in
2625 parallel, using threads. Thus, plugins generally need to use
2626 thread-safe functions from now on.
2627 * collectd: The '-t' command line options allows to perform syntax tests
2628 of the configuration file and exit immediately.
2629 * csv plugin: The new `csv' plugin handles output to `comma separated
2631 * rrdtool plugin: The new `rrdtool' plugin handles output to
2632 RRD-files. Data can be cached to combine multiple updates into one
2633 write to increase IO-performance.
2634 * network plugin: The new `network' plugin handles IO via the network.
2635 It implements a different, much more extensible protocol which can
2636 combine many values in one packet, decreasing the number of UDP-
2637 packets being sent. It can read from and send to the network and
2638 with the appropriate configuration even forward packets to other
2640 * unixsock plugin: The new `unixsock' plugin provides an interface to
2641 communicate with the daemon while it is running. Right now the
2642 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2644 * perl plugin: The new `perl' plugin allows you to write extensions
2645 for collectd in the scripting-language Perl.
2646 * logfile plugin: The new `logfile' plugin writes logmessages to files
2647 or STDOUT or STDERR.
2648 * syslog plugin: The new `syslog' plugin sends logmessages to the
2649 system's syslog daemon.
2650 * entropy plugin: The new `entropy' plugin collects the amount of
2651 entropy currently being available to the system.
2652 * exec plugin: The new `exec' plugin forks child processes and reads
2653 back values provided by the forked processes.
2654 * iptables plugin: The new `iptables' plugin reads counters from
2655 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2657 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2658 to Peter Holik for contributing this plugin.
2659 * nut plugin: The new `nut' plugin connects the upsd of the `network
2660 ups tools' and reads information about the connected UPS.
2661 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2662 connections) field was added by Florent Monbillard.
2663 * collectd-nagios: The new `collectd-nagios' binary queries values
2664 from collectd, parses them and exits according to Nagios-standards.
2665 * manpages: The manpages have been improved a lot.
2667 2007-09-28, Version 3.11.7
2668 * wireless plugin: Correct the handling of cards returning signal and
2669 noise quality as percentage.
2671 2007-08-31, Version 3.11.6
2672 * processes plugin: Fix a potential segmentation fault.
2674 2007-05-29, Version 3.11.5
2675 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2676 * ntpd plugin: Fix a potential buffer overflow.
2677 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2678 were accounted as `zombies'.
2680 2007-04-10, Version 3.11.4
2681 * dns plugin: Change the order of includes to make the plugin compile
2684 2007-03-30, Version 3.11.3
2685 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2686 of the unused `COLLECT_KSTAT'.
2688 2007-02-11, Version 3.11.2
2689 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2690 NULL-pointer may have been passed to `printf' which causes a
2691 segfault with some libcs.
2693 2007-02-10, Version 3.11.1
2694 * df plugin: Some wrong defines have been fixed so the plugin works
2695 under Solaris again.
2696 * dns plugin: The usage of a struct has been fixed to work with
2698 * processes plugin: Some missing defines have been added so the plugin
2699 compiles cleanly under FreeBSD and presumably other UNIXes.
2701 2006-12-22, Version 3.11.0
2702 * collectd: The new command line option `-P' makes it easier for
2703 distributors to change the location of PID-files.
2704 * collectd: The daemon shuts down faster now which makes it easier to
2705 write init.d-scripts for it.
2706 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2707 caused problems every now and then.
2708 * df plugin: New config options allow to ignore certain mountpoints,
2709 filesystem types or devices.
2710 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2711 and interprets it. It collects traffic as well as qtype, opcode and
2713 * email plugin: Sebastian Harl has contributed this plugin which
2714 counts received mails in categories (e. g. ham, spam, virus), spam
2715 score (as given by SpamAssassin) and check types.
2716 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2717 uses `mbmon' to gather information from sensors on the motherboard.
2718 * processes plugin: Collect detailed statistics for configured
2719 processes, that's process and thread count, CPU usage, resident
2720 segment size and pagefaults.
2721 * multimeter plugin: Peter Holik contributed a new plugin which
2722 queries multimeters.
2723 * sensors plugin: Lubos Stanek has put much effort into improving this
2724 plugin, including `extended naming', collection of voltage values
2725 and the possibility to ignore certain values.
2727 2006-12-21, Version 3.10.4
2728 * Max Kellermann has identified a bug in the server routine: When
2729 opening a socket fails the daemon will (re)try opening the socket in
2730 an endless loop, ultimately leading to a `EMFILE' error.
2732 2006-11-04, Version 3.10.3
2733 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2734 ntpd's reply was sent in more than one packet, the buffer size was
2735 calculated incorrectly, resulting in the reading of uninitialized or
2738 2006-11-01, Version 3.10.2
2739 * The sample config file has been improved.
2740 * Errors in the manpages have been corrected.
2741 * The ping-plugin now adds hosts during initialization, not during
2742 startup. This speeds up startup when no network connectivity is
2743 available. Also, the hosts are being added later when the network is
2745 * Improved BSD-support for the df-plugin.
2746 * Fixed syntax errors in the swap-plugin for Mac OS X.
2747 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2749 * Don't disable the mysql-plugin if connecting to the database fails
2750 during initialization. Instead, try again in increasing intervals.
2752 2006-07-19, Version 3.10.1
2753 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2754 the apcups cannot be reached, unconnected sockets will pile up and
2755 eventually lead to `Too many open files' errors.
2757 2006-07-09, Version 3.10.0
2758 * The `disk' plugin has been ported to Darwin.
2759 * The `battery' plugin should work on many Apple computers now.
2760 * The `traffic' plugin can now ignore certain interfaces. Also,
2761 statistics for sent/received packets and errors have been added.
2762 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2763 to Anthony Gialluca for contributing this plugin and providing me
2764 with a test environment :)
2765 * A plugin for monitoring an NTP instance and the local clock drift
2768 2006-06-25, Version 3.9.4
2769 * The Solaris code in the `swap' plugin has been changed to reflect
2770 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2772 * The debugging system has been fixed to work with the Sun libc.
2773 * When built without librrd the variable `operating_mode' could be
2774 uninitialized. Thanks to David Elliot for reporting the bug.
2776 2006-06-01, Version 3.9.3
2777 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2778 operating systems also profit from the changes, but I wasn't able to
2780 * Changed the build system to find the netinet-includes under FreeBSD
2781 and therefore successfully build the `liboping' library there.
2783 2006-05-09, Version 3.9.2
2784 * Applied a patch to the `liboping' library. Due to a bug in the
2785 sequence checking the `ping' plugin stopped working after
2786 approximately 7.6 days.
2788 2006-05-09, Version 3.8.5
2789 * Applied a patch to the `liboping' library. Due to a bug in the
2790 sequence checking the `ping' plugin stopped working after
2791 approximately 7.6 days.
2793 2006-04-21, Version 3.9.1
2794 * Build issues with Solaris and possible other architectures have been
2796 * Problems when building the `apache'-plugin without `libcurl' have
2798 * A bug in the `ping' plugin has been fixed. Sorry folks.
2800 2006-04-02, Version 3.9.0
2801 * A plugin to monitor the Apache webserver has been added.
2802 <http://httpd.apache.org/>
2803 * A plugin to collect statistics about virtual servers using VServer.
2804 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2806 * A plugin for wireless LAN cards has been added. It monitors signal
2807 strength, link quality and noise ratio..
2808 * A plugin for Apple hardware sensors has been added.
2809 * An option to compile collectd with different `step' and `heartbeat'
2810 settings has been added. The size of RRAs is no longer static but
2811 calculated based on the settings for `step' and `width'.
2812 * The `ping' plugin can now be configured to use a certain TTL.
2813 * A plugin to monitor the hardware sensors of Apple computers has been
2815 * The plugins `cpu', `memory', `processes' and `traffic' have been
2816 ported to Mach/Darwin (Mac OS X).
2817 * The `log mode' has been contributed by Christophe Kalt. It writes
2818 the data into text files rather than RRD files.
2820 2006-04-09, Version 3.8.4
2821 * Applied patch by Vincent Stehlé which improves the disk-name
2822 resolution in the `hddtemp' plugin for Linux systems.
2824 2006-04-02, Version 3.8.3
2825 * Applied a patch by James Byers: The MySQL plugin was not working
2826 with MySQL 5.0.2 or later.
2828 2006-03-14, Version 3.8.2
2829 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2830 the GNU libc, because it points to `/etc/fstab' rather than
2833 2006-03-13, Version 3.8.1
2834 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2835 * Fixes in the debian `postinst' and `init.d' scripts.
2837 2006-03-09, Version 3.8.0
2838 * The `ping' plugin no longer uses `libping' but a self written
2839 library named `liboping'. With this library it's possible to ping
2840 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2842 2006-02-18, Version 3.7.2
2843 * A simple bug in the `battery' plugin has been fixed. It should now
2844 work with ACPI based batteries as well. Thanks to Sebastian for
2846 * Fixing a bug that prevented collectd to be built without librrd.
2847 Thanks to Werner Heuser for reporting it.
2849 2006-02-04, Version 3.7.1
2850 * The new network code has been improved to build with older versions
2852 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2853 to Tommie Gannert for this patch.
2855 2006-01-30, Version 3.7.0
2856 * The `battery' plugin has been added. It collects information about
2858 * The MySQL plugin has been improved: It now writes two more RRD
2859 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2860 * The `cpufreq' plugin now reads another file since the file it did
2861 read so far causes much overhead in the kernel. Also, you need root
2862 to read the old file, but not to read the new one.
2863 * The `hddtemp' plugin can now be configured to connect to another
2864 address and/or port than localhost.
2865 * The `df' plugin now prefers `statvfs' over `statfs'.
2866 * The network code has been rewritten. collectd now supports unicast
2867 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2868 be set in the configfile.
2870 2006-01-24, Version 3.6.2
2871 * Due to a bug in the configfile handling collectd wouldn't start in
2872 client mode. This released fixes this.
2874 2006-01-20, Version 3.6.1
2875 * Due to a bug in `configure.in' all modules and the binary were
2876 linked against `libmysqlclient'. This issue is solved by this
2879 2006-01-17, Version 3.6.0
2880 * A config file has been added. This allows for loading only specific
2882 * A `df' plugin has been added.
2883 * A `mysql' plugin has been added.
2884 * The `ping' plugin doesn't entirely give up hope when a socket error
2885 occurred, but will back of and increase the intervals between tries.
2887 2006-01-21, Version 3.5.2
2888 * Fixed yet another bug in the signal handling.. Stupid typo..
2889 * Improved the ping plugin to not give up on socket errors (backport
2892 2005-12-18, Version 3.5.1
2893 * The PID-file is now deleted correctly when shutting down the daemon.
2894 * SIGINT and SIGTERM are now handled correctly.
2896 2005-12-16, Version 3.5.0 (Revision 326)
2897 * A bug in the `load' module under Solaris has been fixed.
2898 * The `users' module has been contributed by Sebastian Harl. It counts
2899 currently logged in users.
2900 * The CPU module now works under FreeBSD without the use of
2901 `libstatgrab', however SMP support is missing.
2902 * The default directories for the RRD files and the PID file now
2903 depend on the compile time setting of `localstatedir'.
2905 2005-11-15, Version 3.4.0 (Revision 236)
2906 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2907 from gentoo's bugzilla for writing the patch.
2908 * The build dependency for librrd has been removed. Binaries built
2909 without librrd are client-only and will multicast their value as
2910 with the `-c' argument.
2911 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2912 * The newly introduced `-f' switch prevents daemon initialization
2913 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2914 Barcellos for this patch.
2916 2005-11-04, Version 3.3.0 (Revision 216)
2917 * New modules have been added:
2918 - `serial', for monitoring traffic on the serial interfaces
2919 - `nfs', for graphing NFS procedure calls
2920 - `tape', traffic from/to tape devices
2921 * The memory.rrd now accepts more than 4Gig of memory.
2923 2005-10-26, Version 3.2.0 (Revision 200)
2924 * Support for graphing the processes has been added (thanks to Lyonel
2926 * If reading from hddtemp fails collectd will increase the time
2927 between polls up to one day.
2928 * The init.d files have been improved.
2929 * Problems with the spec file have been fixed.
2931 2005-10-16, Version 3.1.0 (Revision 194)
2932 * Added the `setsid' syscall to the startup code.
2933 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2935 2005-09-30, Version 3.0.0 (Revision 184)
2936 * The ability to send/receive data to/from the network (think
2937 multicast) has been added.
2938 * Modules have been split up into shared libraries can be loaded at
2939 runtime. The biggest advantage is that the core program doesn't need
2940 to be linked against an external library.
2941 * A patch by George Kargiotakis has been applied: It fixes the sensors
2942 behaviour then more than one sensor is being queried.
2944 2005-09-16, Version 2.1.0 (Revision 172)
2945 * A module for swap statistics has been added.
2947 2005-09-09, Version 2.0.0 (Revision 135)
2948 * Filenames can no longer be configured at program startup. The only
2949 options as of this version are the directory and ping hosts.
2950 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2951 Soft-IRQ statistics are added to `System'.
2952 * Diskstats now collect read and write bytes, not sectors.
2953 * Ping statistics can now be collected for more than one host. There
2954 is no default any more: If no host is given no host will be pinged.
2955 * A self-written patch for libping has been applied so it builds
2958 2005-09-01, Version 1.8.1 (Revision 123)
2959 * Much improved configure-script: libraries and features may now be
2961 * More detailed warnings/error messages when RRD update fails.
2963 2005-08-29, Version 1.8.0:
2964 * Support for collecting disk statistics under Solaris.
2966 2005-08-25, Version 1.7.0:
2967 * Support for libstatgrab[1] for load, memory usage and network
2968 traffic. CPU- and disk-usage are not (yet) supported, since
2969 libstatgrab returns insufficient information. I will contact the
2971 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2972 aren't necessarily counted linear which is now handled correctly.
2973 [1]: http://www.i-scream.org/libstatgrab/
2975 2005-08-21, Version 1.6.0:
2976 * Basic support for Solaris: System load and cpu-usage can be
2977 collected under Solaris, too. Other stats will follow later.
2978 * Many fixes in the autoconf-script
2979 * Collection/Museum scripts have been added under contrib/museum
2980 * collectd may now be started in unprivileged mode, though ping
2981 statistics will not work.
2983 2005-07-17, Version 1.5.1:
2984 * Diskstats-RRDs now use major/minor for naming. Some systems have
2985 weird strings as disk-names..
2987 2005-07-17, Version 1.5:
2988 * A new module, diskstats, has been added. It collects information
2989 about the disks and partitions.
2991 2005-07-11, Version 1.4.2:
2992 * The meminfo module has been changed to work with more platforms
2993 and/or kernel versions.
2995 2005-07-10, Version 1.4.1: Correct traffic stats
2996 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2997 forgot to correct when I changed that module.
2999 2005-07-09, Version 1.4: More traffic stats
3000 * Traffic is now collected for all interfaces that can be found
3001 * Temperature-statistics are read from lm-sensors if available
3003 2005-07-08, Version 1.3: CPU stats
3004 * Collecting CPU statistics now
3006 2005-07-12, Version 1.2: Using syslog
3007 * collectd is now using the syslog facility to report errors, warnings
3009 * The default directory is now /var/db/collectd
3011 2005-07-10, Version 1.1: Minor changes
3012 * Nothing really useful to say ;)
3014 2005-07-09, Version 1.0: Initial Version
3015 * The following modules are provided:
