2143 * bind plugin: Fix collection of the cached RR sets. The number of RR
2144 sets currently in the cache was collected as a counter value, which
2145 is nonsense. Thanks to Bruno Prémont for implementing this.

2190 to STDOUT is compatible with the exec plugin. Thanks to Doug
2191 MacEachern for the patch.
2192 * curl plugin: This new plugin can be used to read web pages and parse
2193 them using the same mechanism that's used in the tail plugin.
2194 * dbi plugin: This new plugin allows you to connect to a variety of
2195 relational databases and use SQL to gather custom statistics from
2196 it. It is similar to the already existing PostgreSQL plugin but uses
2197 libdbi to communicate with the database(s).
2198 * interface plugin: Use the ignorelist framework when selecting /
2199 ignoring interfaces. This allows one to use regular expressions to
2200 select interfaces, too.

2270 installed in a non-standard path. Thanks to Dusty Doris for
2272 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2273 Solaris, in the configure script automatically.
2274 * build system, tcpconns plugin: Check for `kvm_nlist' and
2275 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2276 library with similar functions to the BSD variant, but doesn't
2277 provide these necessary functions.
2278 * collectd.conf(5): Various fixes and clarifications.
2279 * collectd: Remove a GNUism (unnamed unions), thus improving

2284 * filecount plugin: Fix an off-by-one error. This error may cause a
2286 * network plugin: Fix the handling of `type' in the network protocol.
2287 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2288 much larger buffer. This caused the `type' to be transferred much
2289 more often than necessary. In some cases, e. g. the `cpu' and
2290 `cpufreq' plugins being used at the same time, data may be corrupted
2291 in those files. Thanks to Bruno Prémont for debugging and reporting
2293 * processes plugin: Fix a possible segmentation fault when specifying
2294 invalid configuration options.
2295 * unixsock plugin: Make sure the initialization function is run only
2296 once. This resolves a file descriptor leak under systems which run
2297 the initialization more than once, such as Solaris.
2299 2008-10-16, Version 4.5.1
2300 * build system: Change `--enable-<plugin>' to abort with an error if
2301 dependencies are not met. Thanks to Bruno Prémont for the patch.
2302 Also, the poisoning of various string functions has been restricted
2304 * collectd: Fix a memory leak in the global value cache. With every
2305 *missing* value a couple of bytes would be leaked. Another memory
2306 leak in the configuration handling code has been fixed. Thanks to
2307 Niraj Tolia for reporting these issues.
2308 * collectd: Fix an off-by-one error in the ignorelist functionality.
2309 When using regular expressions, the last character would be missing,
2310 possibly matching differently from what one would expect.
2311 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2313 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2314 Linzberger for reporting the bug.
2315 * iptables plugin: Fix an off-by-one error. If a string was just one
2316 character too long, it was truncated instead of reporting an error.
2317 * network plugin: Fix a memory leak in the configuration handling
2318 code. Thanks to Niraj Tolia for reporting this issue.
2319 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2320 * postgresql plugin: Don't reopen connection during reinitialization.
2321 This fixes a bug under Solaris and potentially other platforms.
2322 Missing calls to `PQclear' have been added, too. This fixes memory
2323 leaks. Thanks to ``Admin'' for reporting these bugs.
2324 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2326 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2327 problems with some `libc's. Thanks to Matthias Lay for reporting the
2330 2008-09-04, Version 4.5.0
2331 * collectd: Added the ability to flush certain identifiers.

2337 Notifications upon added and removed sensors can now be generated.
2338 * notify_desktop plugin: This new plugin sends notifications to the
2339 X desktop using the structure defined in the `Desktop Notification
2341 * notify_email plugin: This new plugin sends out notifications via
2342 email, using the `esmtp' library.
2343 * onewire plugin: The new experimental(!) onewire plugin reads values,
2344 such as temperatures, from sensors connected to the computer via the
2346 * perl plugin: Improved synchronized access to internal data structures
2347 and fixed a possible dead-lock.
2348 * perl plugin: Added the ability to flush certain identifiers and marked
2349 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2351 * perl plugin: Added the ability to configure Perl plugins.
2352 * postgresql plugin: The new postgresql plugin collects statistics
2353 about or from a PostgreSQL database.

2355 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2357 * tcpconns plugin: This plugin has been ported to OpenBSD.
2358 * thermal plugin: The new thermal plugin collects system temperatures
2359 using Linux ACPI thermal zone data.
2361 2009-01-02, Version 4.4.5
2362 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2363 file may be in both locations, especially when the database was
2364 installed in a non-standard path. Thanks to Dusty Doris for
2366 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2367 Solaris, in the configure script automatically.
2368 * collectd.conf(5): Various fixes and clarifications.
2369 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2370 portability problems, especially for Solaris.
2371 * dns plugin: Fix a portability problem with NetBSD.
2372 * network plugin: Fix the handling of `type' in the network protocol.
2373 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2374 much larger buffer. This caused the `type' to be transferred much
2375 more often than necessary. In some cases, e. g. the `cpu' and
2376 `cpufreq' plugins being used at the same time, data may be corrupted
2377 in those files. Thanks to Bruno Prémont for debugging and reporting
2379 * unixsock plugin: Make sure the initialization function is run only
2380 once. This resolves a file descriptor leak under systems which run
2381 the initialization more than once, such as Solaris.
2383 2008-10-16, Version 4.4.4
2384 * build system: Change `--enable-<plugin>' to abort with an error if
2385 dependencies are not met. Thanks to Bruno Prémont for the patch.
2386 Also, the poisoning of various string functions has been restricted
2388 * collectd: Fix a memory leak in the global value cache. With every
2389 *missing* value a couple of bytes would be leaked. Another memory
2390 leak in the configuration handling code has been fixed. Thanks to
2391 Niraj Tolia for reporting these issues.
2392 * collectd: Fix an off-by-one error in the ignorelist functionality.
2393 When using regular expressions, the last character would be missing,
2394 possibly matching differently from what one would expect.
2395 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2397 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2398 Linzberger for reporting the bug.

2400 code. Thanks to Niraj Tolia for reporting this issue.
2401 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2402 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2403 problems with some `libc's. Thanks to Matthias Lay for reporting the
2406 2008-09-01, Version 4.4.3
2407 * collectd: Fix a memory leak in the threshold checking code.
2408 * memcached plugin: Fix a too short timeout and a related file
2410 * memory plugin: A typo in the libstatgrab code has been fixed.
2411 * snmp plugin: Fix a possible memory leak.
2413 2008-07-15, Version 4.4.2
2414 * build system: Use pkg-config to detect the upsclient library.
2415 * collectd: Try even harder to determine the endianness of the
2416 architecture collectd is being built on.
2417 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2419 * dns plugin: Fix compilation errors with BIND versions 19991001
2421 * network plugin: Bugfix in the init routine: The init function
2422 cleared a buffer regardless of its contents. This could lead to lost
2423 values under Solaris.
2424 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2425 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2427 * wireless plugin: Work around incorrect noise and power values
2428 returned by some broken drivers.
2430 2008-06-03, Version 4.4.1
2431 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2432 to kyrone for reporting this.
2433 * collectd: Fixed min/max output in notifications generated by
2435 * collectd-nagios: Fix the protocol used to communicate with the
2437 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2438 initialization has errors. An issue with Perl 5.10 has been fixed.
2439 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2440 René Rebe and Siegmund Gorr for reporting this.
2442 2008-05-06, Version 4.4.0
2443 * collectd: Internal code cleanups.
2444 * collectd: Added support for a `Flush' command in the unixsock and
2445 exec plugins. This command can be used to force a plugin (or all) to
2446 flush its values to disk.
2447 * collectd: Thresholds can now be configured to apply to one data
2448 source only, making it possible to configure different thresholds
2449 for each data source.
2450 * apache, nginx plugins: Added the possibility to disable host and/or
2452 * ascent plugin: The new ascent plugin reads and parses the statistics
2453 page of an Ascent server.
2454 * cpu plugin: Support for the statgrab library has been added.
2455 * disk plugin: The possibility to ignore certain disks or collect only
2456 specific disks has been added.

2459 sensor values via IPMI, the intelligent platform management
2461 * iptables plugin: The iptc library that is used by the iptables
2462 plugin has been added to the distribution, because it is not
2463 provided by all distributions and removed from at least one.
2464 * powerdns plugin: The new powerdns plugin reads statistics from an
2465 authoritative or a recursing PowerDNS name server.
2466 * rrdtool plugin: The size of the files generated with the default
2467 configuration has been decreased.
2468 * tail plugin: The new tail plugin can be used to gather statistics by
2469 continuously reading from log files.
2470 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2471 TeamSpeak2 server and collects statistics about the number of users
2472 and number of channels.
2473 * users plugin: Support for the statgrab library has been added.
2474 * vmem plugin: The new vmem plugin collects very detailed statistics
2475 about the virtual memory subsystem of Linux.
2477 2008-08-30, Version 4.3.4
2478 * Build system: Improved detection of and linking with the statgrab
2480 * collectd: Portability fixes, especially to determine endianness more
2482 * Various plugins: Fix format strings.

2496 * build system: Improved detection of several libraries, especially if
2497 they are in non-standard paths.
2498 * build system: Portability fixes: Automatically define "_REENTRANT"
2499 if the libc expects it.
2500 * collectd: Error and warning messages have been improved.
2501 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2503 * apache plugin: Allocate new memory when reading a webpage instead of
2504 using a buffer of static size.
2505 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2507 * hddtemp plugin: Error and warning messages have been improved.
2508 * sensors plugin: Fix sensor collection for some chip types.
2510 2008-03-29, Version 4.3.2
2511 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2512 `Persist' threshold options.
2513 * collectd: Fix handling of missing values in the global value cache.
2514 * collectd: Improved error messages when parsing the configuration.
2515 * sensors plugin: Fix temperature collection with libsensors4.
2516 * unixsock plugin: Fix mixed input and output operation on streams.
2517 * wireless plugin: Fix reading noise value.
2519 2008-03-05, Version 4.3.1
2520 * exec plugin: Set supplementary group IDs.
2522 + Use `memcpy' when constructing/parsing a package to avoid
2523 alignment problems on weird architectures, such as Sparc.
2524 + Translate doubles to/from the x86 byte representation to ensure
2525 cross-platform compatibility.
2526 * ping plugin: Correct the handling of the `TTL' setting.
2527 * swap plugin: Reapply a patch for Solaris.
2528 * tcpconns plugin: Portability improvements.
2530 2008-02-18, Version 4.3.0
2531 * collectd: Notifications have been added to the daemon. Notifications
2532 are status messages that may be associated with a data instance.
2533 * collectd: Threshold checking has been added to the daemon. This
2534 means that you can configure threshold values for each data
2535 instance. If this threshold is exceeded a notification will be
2537 * collectd: The new `FQDNLookup' option tells the daemon to use the
2538 full qualified domain name as the hostname, not just the host part
2539 es returned by `gethostname(2)'.
2540 * collectd: Support for more than one `TypesDB' file has been added.
2541 This is useful when one such file is included in a package but one
2542 wants to add custom type definitions.
2543 * collectd: The `Include' config option has been expanded to handle
2544 entire directories and shell wildcards.
2545 * collectdmon: The new `collectdmon' binary detects when collectd
2546 terminates and automatically restarts it again.
2547 * csv plugin: The CSV plugin is now able to store counter values as a
2548 rate, using the `StoreRates' configuration option.
2549 * exec plugin: Handling of notifications has been added and the
2550 ability to pass arguments to the executed programs has been added.
2551 * hddtemp plugin: The new `TranslateDevicename' option lets you
2552 disable the translation from device names to major-minor-numbers.
2553 * logfile plugin: Handling of notifications has been added.
2554 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2555 domain name lookups in this plugin.
2556 * perl plugin: Many internal changes added support for handling multiple
2557 threads making the plugin reasonably usable inside collectd. The API has
2558 been extended to support notifications and export global variables to
2559 Perl plugins; callbacks now have to be identified by name rather than a
2560 pointer to a subroutine. The plugin is no longer experimental.
2561 * uuid plugin: The new UUID plugin sets the hostname to an unique
2562 identifier for this host. This is meant for setups where each client
2563 may migrate to another physical host, possibly going through one or
2564 more name changes in the process. Thanks to Richard Jones from
2565 Red Hat's Emerging Technology group for this plugin.
2566 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2567 CPU, disk and network statistics about guest systems on the same
2568 physical server. Thanks to Richard Jones from Red Hat's Emerging
2569 Technology group for this plugin.
2571 2008-04-22, Version 4.2.7
2572 * build system: Improved detection of several libraries, especially if
2573 they are in non-standard paths.
2574 * build system: Portability fixes: Automatically define "_REENTRANT"
2575 if the libc expects it.
2576 * collectd: Error and warning messages have been improved.
2577 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2579 * apache plugin: Allocate new memory when reading a webpage instead of
2580 using a buffer of static size.
2581 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2583 * hddtemp plugin: Error and warning messages have been improved.
2584 * sensors plugin: Fix sensor collection for some chip types.

2592 2008-03-04, Version 4.2.5
2593 * apache plugin: Improved initialization and error messages.
2594 * exec plugin: Set supplementary group IDs.
2596 + Create separate threads for reading from the socket and parsing
2597 and dispatching incoming packets. Versions prior to this may have
2598 problems in high-load situations, where the socket receive buffers
2599 overflows, resulting in gaps in the data.
2600 + Use `memcpy' when constructing/parsing a package to avoid
2601 alignment problems on weird architectures, such as Sparc.
2602 + Translate doubles to/from the x86 byte representation to ensure
2603 cross-platform compatibility.
2604 * ping plugin: Correct the handling of the `TTL' setting.
2605 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2606 * swap plugin: Reapply a patch for Solaris.
2607 * tcpconns plugin: Portability improvements.
2609 2008-01-21, Version 4.2.4
2610 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2611 the permission on the socket as documented in the manpage. Thanks to
2612 Evgeny Chukreev for fixing this issue.
2613 * collectd: The documentation has been improved.
2615 2007-12-28, Version 4.2.3
2616 * sensors plugin: Updated the plugin to build and work with version 3
2617 of the libsensors library.
2619 2007-12-15, Version 4.2.2
2620 * nginx plugin: Incorrect comparison of strings lead to a segfault
2621 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2623 * logfile plugin: The config option `Timestamp' was handled
2624 incorrectly and basically always active. Thanks to Luke Heberling
2627 2007-11-08, Version 4.2.1
2628 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2629 enabled on the host.
2630 * snmp plugin: Fix a memory leak.
2632 2007-10-27, Version 4.2.0
2633 * collectd: The new config option `Include' lets you include other
2634 configfiles and thus split up your config into smaller parts. This
2635 may be especially interesting for the snmp plugin to keep the data
2636 definitions separate from the host definitions.
2637 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2638 (number of connections, octets and packets for each service and
2639 destination). Thanks to Sebastian Harl for this plugin.
2640 * memcached plugin: The new `memcached' plugin connects to a memcached
2641 daemon process and collects statistics of this distributed caching
2642 system. Thanks to Antony Dovgal for contributing this plugin.
2643 * nginx plugin: The new `nginx' plugin reads the status page of an
2644 nginx daemon and saves the handled connections and requests.
2645 * perl plugin: Many changes, including the added `EnableDebugger'
2646 config option which lets you debug your Perl plugins more easily.
2647 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2648 be more thread-safe otherwise by locking calls to the library.
2649 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2650 correct the values returned by SNMP-agents. If a <data> block is
2651 defined as `table' the instance is now optional. The sequence number
2652 is used as the type-instance in this case. The new `InstancePrefix'
2653 option allows to add arbitrary prefixes to the type-instance.
2654 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2655 certain TCP connections and what state they're in. This can be used
2656 to see how many connections your FTP server has to handle or how
2657 many outgoing connections your mailserver has open.
2659 2008-01-11, Version 4.1.6
2660 * unixsock plugin: A bug in the unixsock plugin caused it not to set

2672 * Build system: Improve detection of the rrd library, especially if
2673 it's in a non-standard location.
2674 * Build system: A bug when parsing the argument for
2675 `--with-libnetsnmp' has been fixed.
2676 * collectd: Implement `strerror_r' if the libc doesn't provide it.

2678 a deadlock or delay when shutting down the daemon.
2679 * snmp plugin: Fix a memory leak.
2681 2007-10-24, Version 4.1.3
2682 * collectd: A build issue under Solaris has been resolved by renaming
2684 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2685 be more thread-safe otherwise by locking calls to the library.
2687 2007-09-28, Version 4.1.2
2688 * apcups plugin: Fix reporting of the `load percent' data.
2689 * wireless plugin: Correct the handling of cards returning signal and
2690 noise quality as percentage.

2694 includes (i. e. Debian Sarge) have been fixed.
2695 * snmp plugin: Fix a potential segfault when a host times out. Add
2696 support for the `timeticks' type.
2698 2007-09-12, Version 4.1.1
2699 * Build system: The detection of `libnetlink' has been improved.
2700 * collectd: The documentation has been fixed in numerous places.
2701 * exec plugin: Setting the group under which to run a program has been
2703 * collectd: The `sstrerror' function was improved to work correctly
2704 with the broken GNU version of `strerror_r'.
2705 * collectd: Write an error message to STDERR when loading of a plugin
2707 * apcups plugin: Fix the `types' used to submit the values: They still
2708 has an `apcups_' prefix which doesn't work anymore.
2709 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2710 whatever the client thinks is `now'..
2712 2007-09-01, Version 4.1.0
2713 * Build system: The build system has been changed to automatically
2714 disable all plugins, which are missing dependencies. The dependency
2715 checking has been removed from the plugins themselves to remove
2717 * Flexible interval: The interval of collected data is now sent along
2718 with the data itself over the network, so that the interval-settings
2719 of server and clients no longer needs to match.
2720 * netlink plugin: The new `netlink' plugin connects to the Linux
2721 kernel using a netlink socket and uses it to query information about
2722 interfaces, qdiscs and classes.
2723 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2724 to not block data collection.
2725 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2726 network devices, such as switches, routers, thermometers, rack
2727 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2729 * unixsock plugin: Added the `LISTVAL' command.
2730 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2731 of music played with xmms.
2733 2007-09-28, Version 4.0.9
2734 * apcups plugin: Fix reporting of the `load percent' data.
2735 * wireless plugin: Correct the handling of cards returning signal and
2736 noise quality as percentage.
2737 * perl plugin: Fix a possible buffer overflow in get_module_name().
2739 2007-09-12, Version 4.0.8
2740 * collectd: The `sstrerror' function was improved to work correctly
2741 with the broken GNU version of `strerror_r'.
2742 * collectd: Write an error message to STDERR when loading of a plugin
2744 * apcups plugin: Fix the `types' used to submit the values: They still
2745 has an `apcups_' prefix which doesn't work anymore.
2746 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2747 whatever the client thinks is `now'..
2749 2007-08-26, Version 4.0.7
2750 * documentation: Some typos have been fixed and some information has
2752 * build system: Many fixes for detecting libraries in unusual places,
2753 such as on RedHat systems. The affected libraries are `libcurl',
2754 `libmysql', and `libupsclient'.
2755 * network plugin: Allow the `Port' option to be specified as a number
2756 (i. e. without quotes).
2757 * nut plugin: A fix allows linking the nut plugin against
2758 libupsclient, version >= 2.2.0.
2759 * processes plugin: Fix a potential segmentation fault.
2761 2007-07-30, Version 4.0.6
2762 * sensors plugin: Fix the ignorelist functionality: Only the `type
2763 instance' was used to match against the list, but the documentation
2764 told otherwise. This release fixes the code, so it complies with the
2766 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2767 configuration messages will end up in the logging facility.
2768 * conrtib/fedora: The contributed specfile for Fedora has been
2771 2007-07-05, Version 4.0.5
2772 * Portability: More fixes for OpenBSD have been included.
2774 2007-06-24, Version 4.0.4
2775 * cpu plugin: Fixed the Solaris code.
2776 * dns plugin: Fixed a build issue for OpenBSD.
2777 * interface plugin: Fixed the Solaris code.
2778 * load plugin: Fixed the alternative `/proc' Linux code.
2779 * memory plugin: Fixed the Solaris code.
2780 * oconfig: Don't require `-lfl' anymore.
2782 2007-06-19, Version 4.0.3
2783 * cpu plugin: Fix the Darwin / Mac OS X code.
2784 * ping plugin: Use the return value of `getpid', not its address.
2785 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2786 initialized correctly.
2787 * configure: Added `--with-nan-emulation' to aid cross compilation.
2789 2007-06-12, Version 4.0.2
2790 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2791 they're given in numerically form.
2793 2007-06-07, Version 4.0.1
2794 * iptables plugin: A bug in the configuration routine has been fixed.
2795 Setting a comment in the configfile will no longer cause a
2798 2007-06-03, Version 4.0.0
2799 * collectd: The plugin-infrastructure has been changed to allow for
2800 more types of plugins, namely `write' and `log' plugins.
2801 * collectd: The read-function has been changed to read many plugins in
2802 parallel, using threads. Thus, plugins generally need to use
2803 thread-safe functions from now on.
2804 * collectd: The '-t' command line options allows to perform syntax tests
2805 of the configuration file and exit immediately.
2806 * csv plugin: The new `csv' plugin handles output to `comma separated
2808 * rrdtool plugin: The new `rrdtool' plugin handles output to
2809 RRD-files. Data can be cached to combine multiple updates into one
2810 write to increase IO-performance.
2811 * network plugin: The new `network' plugin handles IO via the network.
2812 It implements a different, much more extensible protocol which can
2813 combine many values in one packet, decreasing the number of UDP-
2814 packets being sent. It can read from and send to the network and
2815 with the appropriate configuration even forward packets to other
2817 * unixsock plugin: The new `unixsock' plugin provides an interface to
2818 communicate with the daemon while it is running. Right now the
2819 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2821 * perl plugin: The new `perl' plugin allows you to write extensions
2822 for collectd in the scripting-language Perl.
2823 * logfile plugin: The new `logfile' plugin writes logmessages to files
2824 or STDOUT or STDERR.
2825 * syslog plugin: The new `syslog' plugin sends logmessages to the
2826 system's syslog daemon.
2827 * entropy plugin: The new `entropy' plugin collects the amount of
2828 entropy currently being available to the system.
2829 * exec plugin: The new `exec' plugin forks child processes and reads
2830 back values provided by the forked processes.
2831 * iptables plugin: The new `iptables' plugin reads counters from
2832 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2834 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2835 to Peter Holik for contributing this plugin.
2836 * nut plugin: The new `nut' plugin connects the upsd of the `network
2837 ups tools' and reads information about the connected UPS.
2838 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2839 connections) field was added by Florent Monbillard.
2840 * collectd-nagios: The new `collectd-nagios' binary queries values
2841 from collectd, parses them and exits according to Nagios-standards.
2842 * manpages: The manpages have been improved a lot.
2844 2007-09-28, Version 3.11.7
2845 * wireless plugin: Correct the handling of cards returning signal and
2846 noise quality as percentage.
2848 2007-08-31, Version 3.11.6
2849 * processes plugin: Fix a potential segmentation fault.
2851 2007-05-29, Version 3.11.5
2852 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2853 * ntpd plugin: Fix a potential buffer overflow.
2854 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2855 were accounted as `zombies'.
2857 2007-04-10, Version 3.11.4
2858 * dns plugin: Change the order of includes to make the plugin compile
2861 2007-03-30, Version 3.11.3
2862 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2863 of the unused `COLLECT_KSTAT'.
2865 2007-02-11, Version 3.11.2
2866 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2867 NULL-pointer may have been passed to `printf' which causes a
2868 segfault with some libcs.
2870 2007-02-10, Version 3.11.1
2871 * df plugin: Some wrong defines have been fixed so the plugin works
2872 under Solaris again.
2873 * dns plugin: The usage of a struct has been fixed to work with
2875 * processes plugin: Some missing defines have been added so the plugin
2876 compiles cleanly under FreeBSD and presumably other UNIXes.
2878 2006-12-22, Version 3.11.0
2879 * collectd: The new command line option `-P' makes it easier for
2880 distributors to change the location of PID-files.
2881 * collectd: The daemon shuts down faster now which makes it easier to
2882 write init.d-scripts for it.
2883 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2884 caused problems every now and then.
2885 * df plugin: New config options allow to ignore certain mountpoints,
2886 filesystem types or devices.
2887 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2888 and interprets it. It collects traffic as well as qtype, opcode and
2890 * email plugin: Sebastian Harl has contributed this plugin which
2891 counts received mails in categories (e. g. ham, spam, virus), spam
2892 score (as given by SpamAssassin) and check types.
2893 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2894 uses `mbmon' to gather information from sensors on the motherboard.
2895 * processes plugin: Collect detailed statistics for configured
2896 processes, that's process and thread count, CPU usage, resident
2897 segment size and pagefaults.
2898 * multimeter plugin: Peter Holik contributed a new plugin which
2899 queries multimeters.
2900 * sensors plugin: Lubos Stanek has put much effort into improving this
2901 plugin, including `extended naming', collection of voltage values
2902 and the possibility to ignore certain values.
2904 2006-12-21, Version 3.10.4
2905 * Max Kellermann has identified a bug in the server routine: When
2906 opening a socket fails the daemon will (re)try opening the socket in
2907 an endless loop, ultimately leading to a `EMFILE' error.
2909 2006-11-04, Version 3.10.3
2910 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2911 ntpd's reply was sent in more than one packet, the buffer size was
2912 calculated incorrectly, resulting in the reading of uninitialized or
2915 2006-11-01, Version 3.10.2
2916 * The sample config file has been improved.
2917 * Errors in the manpages have been corrected.
2918 * The ping-plugin now adds hosts during initialization, not during
2919 startup. This speeds up startup when no network connectivity is
2920 available. Also, the hosts are being added later when the network is
2922 * Improved BSD-support for the df-plugin.
2923 * Fixed syntax errors in the swap-plugin for Mac OS X.
2924 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2926 * Don't disable the mysql-plugin if connecting to the database fails
2927 during initialization. Instead, try again in increasing intervals.
2929 2006-07-19, Version 3.10.1
2930 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2931 the apcups cannot be reached, unconnected sockets will pile up and
2932 eventually lead to `Too many open files' errors.
2934 2006-07-09, Version 3.10.0
2935 * The `disk' plugin has been ported to Darwin.
2936 * The `battery' plugin should work on many Apple computers now.
2937 * The `traffic' plugin can now ignore certain interfaces. Also,
2938 statistics for sent/received packets and errors have been added.
2939 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2940 to Anthony Gialluca for contributing this plugin and providing me
2941 with a test environment :)
2942 * A plugin for monitoring an NTP instance and the local clock drift
2945 2006-06-25, Version 3.9.4
2946 * The Solaris code in the `swap' plugin has been changed to reflect
2947 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2949 * The debugging system has been fixed to work with the Sun libc.
2950 * When built without librrd the variable `operating_mode' could be
2951 uninitialized. Thanks to David Elliot for reporting the bug.
2953 2006-06-01, Version 3.9.3
2954 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2955 operating systems also profit from the changes, but I wasn't able to
2957 * Changed the build system to find the netinet-includes under FreeBSD
2958 and therefore successfully build the `liboping' library there.
2960 2006-05-09, Version 3.9.2
2961 * Applied a patch to the `liboping' library. Due to a bug in the
2962 sequence checking the `ping' plugin stopped working after
2963 approximately 7.6 days.
2965 2006-05-09, Version 3.8.5
2966 * Applied a patch to the `liboping' library. Due to a bug in the
2967 sequence checking the `ping' plugin stopped working after
2968 approximately 7.6 days.
2970 2006-04-21, Version 3.9.1
2971 * Build issues with Solaris and possible other architectures have been
2973 * Problems when building the `apache'-plugin without `libcurl' have
2975 * A bug in the `ping' plugin has been fixed. Sorry folks.
2977 2006-04-02, Version 3.9.0
2978 * A plugin to monitor the Apache webserver has been added.
2979 <http://httpd.apache.org/>
2980 * A plugin to collect statistics about virtual servers using VServer.
2981 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2983 * A plugin for wireless LAN cards has been added. It monitors signal
2984 strength, link quality and noise ratio..
2985 * A plugin for Apple hardware sensors has been added.
2986 * An option to compile collectd with different `step' and `heartbeat'
2987 settings has been added. The size of RRAs is no longer static but
2988 calculated based on the settings for `step' and `width'.
2989 * The `ping' plugin can now be configured to use a certain TTL.
2990 * A plugin to monitor the hardware sensors of Apple computers has been
2992 * The plugins `cpu', `memory', `processes' and `traffic' have been
2993 ported to Mach/Darwin (Mac OS X).
2994 * The `log mode' has been contributed by Christophe Kalt. It writes
2995 the data into text files rather than RRD files.
2997 2006-04-09, Version 3.8.4
2998 * Applied patch by Vincent Stehlé which improves the disk-name
2999 resolution in the `hddtemp' plugin for Linux systems.
3001 2006-04-02, Version 3.8.3
3002 * Applied a patch by James Byers: The MySQL plugin was not working
3003 with MySQL 5.0.2 or later.
3005 2006-03-14, Version 3.8.2
3006 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3007 the GNU libc, because it points to `/etc/fstab' rather than
3010 2006-03-13, Version 3.8.1
3011 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3012 * Fixes in the debian `postinst' and `init.d' scripts.
3014 2006-03-09, Version 3.8.0
3015 * The `ping' plugin no longer uses `libping' but a self written
3016 library named `liboping'. With this library it's possible to ping
3017 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3019 2006-02-18, Version 3.7.2
3020 * A simple bug in the `battery' plugin has been fixed. It should now
3021 work with ACPI based batteries as well. Thanks to Sebastian for
3023 * Fixing a bug that prevented collectd to be built without librrd.
3024 Thanks to Werner Heuser for reporting it.
3026 2006-02-04, Version 3.7.1
3027 * The new network code has been improved to build with older versions
3029 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3030 to Tommie Gannert for this patch.
3032 2006-01-30, Version 3.7.0
3033 * The `battery' plugin has been added. It collects information about
3035 * The MySQL plugin has been improved: It now writes two more RRD
3036 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3037 * The `cpufreq' plugin now reads another file since the file it did
3038 read so far causes much overhead in the kernel. Also, you need root
3039 to read the old file, but not to read the new one.
3040 * The `hddtemp' plugin can now be configured to connect to another
3041 address and/or port than localhost.
3042 * The `df' plugin now prefers `statvfs' over `statfs'.
3043 * The network code has been rewritten. collectd now supports unicast
3044 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3045 be set in the configfile.
3047 2006-01-24, Version 3.6.2
3048 * Due to a bug in the configfile handling collectd wouldn't start in
3049 client mode. This released fixes this.
3051 2006-01-20, Version 3.6.1
3052 * Due to a bug in `configure.in' all modules and the binary were
3053 linked against `libmysqlclient'. This issue is solved by this
3056 2006-01-17, Version 3.6.0
3057 * A config file has been added. This allows for loading only specific
3059 * A `df' plugin has been added.
3060 * A `mysql' plugin has been added.
3061 * The `ping' plugin doesn't entirely give up hope when a socket error
3062 occurred, but will back of and increase the intervals between tries.
3064 2006-01-21, Version 3.5.2
3065 * Fixed yet another bug in the signal handling.. Stupid typo..
3066 * Improved the ping plugin to not give up on socket errors (backport
3069 2005-12-18, Version 3.5.1
3070 * The PID-file is now deleted correctly when shutting down the daemon.
3071 * SIGINT and SIGTERM are now handled correctly.
3073 2005-12-16, Version 3.5.0 (Revision 326)
3074 * A bug in the `load' module under Solaris has been fixed.
3075 * The `users' module has been contributed by Sebastian Harl. It counts
3076 currently logged in users.
3077 * The CPU module now works under FreeBSD without the use of
3078 `libstatgrab', however SMP support is missing.
3079 * The default directories for the RRD files and the PID file now
3080 depend on the compile time setting of `localstatedir'.
3082 2005-11-15, Version 3.4.0 (Revision 236)
3083 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3084 from gentoo's bugzilla for writing the patch.
3085 * The build dependency for librrd has been removed. Binaries built
3086 without librrd are client-only and will multicast their value as
3087 with the `-c' argument.
3088 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3089 * The newly introduced `-f' switch prevents daemon initialization
3090 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3091 Barcellos for this patch.
3093 2005-11-04, Version 3.3.0 (Revision 216)
3094 * New modules have been added:
3095 - `serial', for monitoring traffic on the serial interfaces
3096 - `nfs', for graphing NFS procedure calls
3097 - `tape', traffic from/to tape devices
3098 * The memory.rrd now accepts more than 4Gig of memory.
3100 2005-10-26, Version 3.2.0 (Revision 200)
3101 * Support for graphing the processes has been added (thanks to Lyonel
3103 * If reading from hddtemp fails collectd will increase the time
3104 between polls up to one day.
3105 * The init.d files have been improved.
3106 * Problems with the spec file have been fixed.
3108 2005-10-16, Version 3.1.0 (Revision 194)
3109 * Added the `setsid' syscall to the startup code.
3110 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3112 2005-09-30, Version 3.0.0 (Revision 184)
3113 * The ability to send/receive data to/from the network (think
3114 multicast) has been added.
3115 * Modules have been split up into shared libraries can be loaded at
3116 runtime. The biggest advantage is that the core program doesn't need
3117 to be linked against an external library.
3118 * A patch by George Kargiotakis has been applied: It fixes the sensors
3119 behaviour then more than one sensor is being queried.
3121 2005-09-16, Version 2.1.0 (Revision 172)
3122 * A module for swap statistics has been added.
3124 2005-09-09, Version 2.0.0 (Revision 135)
3125 * Filenames can no longer be configured at program startup. The only
3126 options as of this version are the directory and ping hosts.
3127 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3128 Soft-IRQ statistics are added to `System'.
3129 * Diskstats now collect read and write bytes, not sectors.
3130 * Ping statistics can now be collected for more than one host. There
3131 is no default any more: If no host is given no host will be pinged.
3132 * A self-written patch for libping has been applied so it builds
3135 2005-09-01, Version 1.8.1 (Revision 123)
3136 * Much improved configure-script: libraries and features may now be
3138 * More detailed warnings/error messages when RRD update fails.
3140 2005-08-29, Version 1.8.0:
3141 * Support for collecting disk statistics under Solaris.
3143 2005-08-25, Version 1.7.0:
3144 * Support for libstatgrab[1] for load, memory usage and network
3145 traffic. CPU- and disk-usage are not (yet) supported, since
3146 libstatgrab returns insufficient information. I will contact the
3148 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3149 aren't necessarily counted linear which is now handled correctly.
3150 [1]: http://www.i-scream.org/libstatgrab/
3152 2005-08-21, Version 1.6.0:
3153 * Basic support for Solaris: System load and cpu-usage can be
3154 collected under Solaris, too. Other stats will follow later.
3155 * Many fixes in the autoconf-script
3156 * Collection/Museum scripts have been added under contrib/museum
3157 * collectd may now be started in unprivileged mode, though ping
3158 statistics will not work.
3160 2005-07-17, Version 1.5.1:
3161 * Diskstats-RRDs now use major/minor for naming. Some systems have
3162 weird strings as disk-names..
3164 2005-07-17, Version 1.5:
3165 * A new module, diskstats, has been added. It collects information
3166 about the disks and partitions.
3168 2005-07-11, Version 1.4.2:
3169 * The meminfo module has been changed to work with more platforms
3170 and/or kernel versions.
3172 2005-07-10, Version 1.4.1: Correct traffic stats
3173 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3174 forgot to correct when I changed that module.
3176 2005-07-09, Version 1.4: More traffic stats
3177 * Traffic is now collected for all interfaces that can be found
3178 * Temperature-statistics are read from lm-sensors if available
3180 2005-07-08, Version 1.3: CPU stats
3181 * Collecting CPU statistics now
3183 2005-07-12, Version 1.2: Using syslog
3184 * collectd is now using the syslog facility to report errors, warnings
3186 * The default directory is now /var/db/collectd
3188 2005-07-10, Version 1.1: Minor changes
3189 * Nothing really useful to say ;)
3191 2005-07-09, Version 1.0: Initial Version
3192 * The following modules are provided:
