2140 * rrdcached plugin: Work-around for a bug in RRDtool 1.4rc2 has been
2141 added.
2142 * snmp plugin: Handling of negative values has been fixed. Strings
2143 containing control characters are now interpreted as hex-strings.
2144 * unixsock plugin: A memory leak in the LISTVAL command has been
2145 fixed. Thanks to Ben Knight for his patch.
2147 2009-10-03, Version 4.7.4
2148 * Build system: Issues when building the iptables plugin have been
2149 fixed.
2150 * exec plugin: Clear the signal block mask before calling exec(2).
2151 * perl plugin: Declare the “environ” variable. This solves build
2152 issues on some platforms.
2153 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
2154 Andrés J. Díaz for the patch.
2155 * unixsock plugin: Fix a (well hidden) race condition related to file
2156 descriptor handling.
2158 2009-09-13, Version 4.7.3
2159 * collectd: Fix a possible but very rare invalid “free” in the caching
2160 code. Thanks to Sebastian Harl for the patch.
2161 * collectd: Remove old values when a cache entry is marked as missing.
2162 This way the “GETVAL” command of the UnixSock plugin doesn't return
2163 old, no longer valid values when this happens. Thanks to Andrés J.
2164 Díaz for the patch.
2165 * collectd: The “plugin_unregister_read” function has been fixed.
2166 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
2167 to follow redirects. Thanks to Joey Hess for reporting this bug.
2168 * df plugin: Check the ignorelist before stating the file system,
2169 possibly reducing the number of stats considerably. Thanks to Joey
2170 Hess for reporting this bug.
2171 * iptables plugin: Support for the new libiptc API has been added.
2172 Thanks to Sebastian Harl for the patch. The build system has been
2173 updated to the plugin only includes the shipped header files when it
2174 is linked with the shipped library, too.
2175 * java plugin: Delay creating the JVM until after the daemon has
2176 forked. The JVM internally creates threads that are lost when
2177 forking. This means that Java-based plugins are now configured
2178 during the init-phase, i. e. later than other plugins.
2179 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
2180 to Alan Pevec for the patch.
2181 * network plugin: Fix the handling of the “CacheFlush” option: The
2182 value was assigned to a wrong variable. The initialization of the
2183 gcrypt library, which is used for signing / encrypting traffic, has
2184 been fixed. Thanks to Luke Heberling for the patch.
2185 * powerdns plugin: Set a timeout when reading data from the datagram
2186 socket. Handling of the “LocalSocket” option has been fixed. An
2187 incorrectly used “type” has been corrected. Thanks to Luke Heberling
2188 for his patches.
2190 2009-07-19, Version 4.7.2
2191 * Build system: Support for `DESTDIR' has been fixed in the Java

2203 details have been added to the configuration summary. Support for
2204 libtool 2.2 has been added.
2205 * collectd: Two bugs with the threshold checking have been fixed. The
2206 first one prevented thresholds to be checked at all, the second one
2207 caused wrong behavior with the persistency option. Thanks to Andrés
2208 J. Díaz for fixing these problems.
2209 * collectd: Handling of the `Include' configuration option has been
2210 fixed.
2211 * rrdtool plugin: Make sure initialization is run only once. This
2212 resolves problems under Solaris and potentially other systems.
2213 Thanks to Amit Gupta for reporting this bug.
2214 * java plugin: Make it possible to use dots ('.') instead of slashes
2215 ('/') as the class separator. Thanks to Randy Rizun for pointing
2216 this out.
2217 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
2218 to Doug MacEachern for the patch.
2220 2009-05-11, Version 4.7.0
2221 * apache plugin: Support to query multiple servers has been added.

2224 improved. Thanks to Amit Gupta for the patch.
2225 * conntrack plugin: The new conntrack plugin collects the connection
2226 tracking table size. Thanks to Tomasz Pala for the patch.
2227 * fscache plugin: The new fscache plugin collects statistics about
2228 Linux' file-system based caching framework. Thanks to Edward
2229 Konetzko for the patch.
2230 * gmond plugin: The new gmond plugin can receive and interpret
2231 multicast traffic from Ganglia's gmond daemon.
2232 * java plugin: The new java plugin exports the collectd API to Java,
2233 making it possible to write extensions to collectd in Java.
2234 * memcachec plugin: The new memcachec plugin queries data from a
2235 memcached daemon and parses it similar to the cURL plugin. Thanks to
2236 Doug MacEachern for the initial code.
2237 * memcached plugin: Support for connections over UNIX domain sockets
2238 has been added. Thanks to Franck Lombardi for the patch.
2239 * memory plugin: Support for OpenBSD and possibly other *BSDs has been
2240 added. Thanks to Simon Kuhnle for the patch.
2241 * mysql plugin: Support to query multiple databases has been added.
2242 Thanks to Doug MacEachern for the patch.
2243 * mysql plugin: Master/slave statistics have been added.
2244 * mysql plugin: Lock statistics have been added. Thanks to Rodolphe
2245 Quiédeville for the patch.
2246 * network plugin: The possibility to sign or encrypt network traffic
2247 has been added.
2248 * protocols plugin: The new protocols plugin provides information
2249 about network protocols, such as IP, TCP and UDP.
2250 * snmp plugin: The intervals given in the configuration of the SNMP
2251 plugin must no longer be a multiple of the global interval.
2252 * table plugin: The new Table plugin provides parsing for table-like
2253 structured files, such as many files beneath /proc.
2254 * ted plugin: The new TED plugin reads power consumption measurements
2255 from “The Energy Detective” (TED). Thanks to Eric Reed for this
2256 plugin.
2257 * onewire plugin: The new `Interval' option allows collecting
2258 information from OneWire sensors at arbitrary intervals.
2259 * ping plugin: Support for collecting the drop rate and standard
2260 deviation of round-trip times has been added.
2261 * uptime plugin: The new uptime plugin can collect the server's
2262 uptime. Thanks to Marco Chiappero for the patch.
2264 2009-09-10, Version 4.6.5
2265 * collectd: Remove old values when a cache entry is marked as missing.
2266 This way the “GETVAL” command of the UnixSock plugin doesn't return
2267 old, no longer valid values when this happens. Thanks to Andrés J.
2268 Díaz for the patch.
2269 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
2270 to follow redirects. Thanks to Joey Hess for reporting this bug.
2271 * df plugin: Check the ignorelist before stating the file system,
2272 possibly reducing the number of stats considerably. Thanks to Joey
2273 Hess for reporting this bug.
2274 * iptables plugin: Support for the new libiptc API has been added.
2275 Thanks to Sebastian Harl for the patch. The build system has been
2276 updated to the plugin only includes the shipped header files when it

2278 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
2279 to Alan Pevec for the patch.
2280 * powerdns plugin: Set a timeout when reading data from the datagram
2281 socket. Handling of the “LocalSocket” option has been fixed. An
2282 incorrectly used “type” has been corrected. Thanks to Luke Heberling
2283 for his patches.

2291 for reporting the bug.
2293 2009-06-02, Version 4.6.3
2294 * Build system, various plugins: Many build fixes for FreeBSD,
2295 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2296 for many fixes and providing a build system for many platforms,
2297 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2298 providing an OpenBSD system.
2299 * collectd: Two bugs with the threshold checking have been fixed. The
2300 first one prevented thresholds to be checked at all, the second one
2301 caused wrong behavior with the persistency option. Thanks to Andrés
2302 J. Díaz for fixing these problems.
2303 * collectd: Handling of the `Include' configuration option has been
2304 fixed.
2305 * battery plugin: Don't complain about a missing directory every
2306 interval.
2307 * exec plugin: Allow executed programs to close STDERR. Thanks to
2308 Thorsten von Eicken for reporting this problem.
2309 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
2310 Tomasz Pala for the patch.
2311 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2312 the patch.
2313 * memory plugin: Fix a potential problem under Solaris.
2314 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
2315 to Doug MacEachern for the patch.
2317 2009-03-18, Version 4.6.2
2318 * collectd: Some Solaris utility code has been improved.
2319 * filter subsystem: Allow `Chains' without default targets.
2320 * liboping: A patch to comply with strict aliasing rules has been
2321 added.
2322 * timediff match: Fix a typo: The match was registered with a wrong
2323 name which prevented this match to be used as documented. Thanks to
2324 Bruno Prémont for finding this problem.
2325 * bind plugin: Fix collection of the cached RR sets. The number of RR
2326 sets currently in the cache was collected as a counter value, which
2327 is nonsense. Thanks to Bruno Prémont for implementing this.
2328 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2329 primarily BSDs, don't take it well and crash.
2330 * oracle plugin: Portability to 64 bit systems has been improved.
2331 * postgresql plugin: The default configuration has been improved.
2332 * rrdtool plugin: Fix a possible race condition: If the network plugin
2333 is brought and dispatches a value before the rrdtool plugin is
2334 initialized, the daemon may crash.
2336 2009-02-22, Version 4.6.1
2337 * collectd: Many documentation fixes.
2338 * Collectd::Unixsock: Error handling has been improved.
2339 * regex match: Don't link with the PCRE library.
2340 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
2341 for finding and fixing most of them.
2342 * ipmi plugin: Fix an off-by-one error which could cause segmentation
2343 faults. Thanks to Peter Holik for his patch.
2345 2009-02-16, Version 4.6.0
2346 * collectd: Added the `filter chain' infrastructure, which allows the
2347 user to use `matches' and `targets' to control value processing.
2348 * collectd: The new `-T' command line argument allows more in-depth
2349 testing of a configuration. Thanks to Doug MacEachern for the patch.
2350 * collectd-nagios: The Nagios integration command has been updated to
2351 use libcollectdclient. The `percentage' aggregation function has
2352 been added. Thanks to Fabian Linzberger for the patch.
2353 * libcollectdclient: A library which abstracts communication with the
2354 unixsock plugin for clients has been added.
2355 * regex match: Match values by their identifies using regular
2356 expressions.
2357 * timediff match: Match for values with an invalid timestamp.
2358 * value match: Select values by their data sources' values.
2359 * notification target: Create and dispatch a notification.
2360 * replace target: Replace parts of an identifier using regular
2361 expressions.
2362 * set target: Set (overwrite) entire parts of an identifier.
2363 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
2364 statistics, allowing very detailed name server statistics. Thanks to
2365 Bruno Prémont for this plugin.
2366 * cpu plugin: Report `interrupt' separately when using
2367 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
2368 example for native OpenBSD support, has been added. Thanks to Simon
2369 Kuhnle for the patch.
2370 * csv plugin: Make it possible to write values to STDOUT instead of
2371 files. This is meant for testing purposes mostly. The output written
2372 to STDOUT is compatible with the exec plugin. Thanks to Doug
2373 MacEachern for the patch.
2374 * curl plugin: This new plugin can be used to read web pages and parse
2375 them using the same mechanism that's used in the tail plugin.
2376 * dbi plugin: This new plugin allows you to connect to a variety of
2377 relational databases and use SQL to gather custom statistics from
2378 it. It is similar to the already existing PostgreSQL plugin but uses
2379 libdbi to communicate with the database(s).
2380 * interface plugin: Use the ignorelist framework when selecting /
2381 ignoring interfaces. This allows one to use regular expressions to
2382 select interfaces, too.
2383 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
2384 Thanks to Bruno Prémont for this patch.
2385 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
2386 for the patch.
2387 * mysql plugin: Allow connecting to a database via the UNIX domain
2388 socket, too. Thanks to Mirko Buffoni for the patch.
2389 * network plugin: Further performance improvements for the receive
2390 code. This hopefully will help very large setups.
2391 * openvpn plugin: This new plugin collects statistics provided by the
2392 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
2393 * oracle plugin: This new plugin allows you to connect to an Oracle
2394 database and use SQL to gather custom statistics from it. It is
2395 similar to the already existing PostgreSQL plugin.
2396 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
2397 have been added.
2398 * perl plugin: Export the newly added plugin_write() to Perl plugins.
2399 * perl plugin: Added support for `notification meta data'.
2400 * perl plugin: Added support for the `filter chain' infrastructure by
2401 allowing plugins to register `matches' and `targets'.
2402 * postgresql plugin: The preferred configuration syntax has been
2403 updated to be in line with the syntax used by the new dbi and oracle
2404 plugins. The compatibility code for the old syntax is present.
2405 Support for the new `Result' blocks and the interval parameter has
2406 been added.
2407 * processes plugin: Stacksize and virtual memory usage statistics have
2408 been added. Portability fixes.
2409 * rrdcached plugin: This new plugin uses the (still in development)
2410 RRD accelerator daemon, rrdcached. This daemon works very similar to
2411 the original rrdtool plugin of collectd, but adds some more nice
2412 features.
2413 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2414 added.
2416 2009-05-09, Version 4.5.4
2417 * Build system, various plugins: Many build fixes for FreeBSD,
2418 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2419 for many fixes and providing a build system for many platforms,
2420 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2421 providing an OpenBSD system.
2422 * collectd: Fix a potential race condition when creating directories.
2423 * battery plugin: Don't complain about a missing directory every
2424 interval.
2425 * dns plugin: Slight portability fixes.
2426 * exec plugin: Allow executed programs to close STDERR. Thanks to
2427 Thorsten von Eicken for reporting this problem.
2428 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
2429 Tomasz Pala for the patch.
2430 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2431 the patch.
2432 * rrdtool plugin: Fix a possible race condition: If the network plugin
2433 is initialized and dispatches a value before the rrdtool plugin is
2434 initialized, the daemon may crash.
2435 * memory plugin: Fix a potential problem under Solaris.
2437 2009-02-22, Version 4.5.3
2438 * build system: The check for libupsclient even when `pkg-config' is
2439 not available.
2440 * collectd: Fix error handling in the global cache.
2441 * Collectd::Unixsock: Error handling has been improved.
2442 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
2443 patch.
2444 * ipmi plugin: Fix an off-by-one error which could cause segmentation
2445 faults. Thanks to Peter Holik for his patch.
2446 * tcpconns plugin: An endianness problem has been fixed in the *BSD
2447 code. Thanks to "thated" for reporting this.
2449 2009-01-02, Version 4.5.2
2450 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2451 file may be in both locations, especially when the database was
2452 installed in a non-standard path. Thanks to Dusty Doris for
2453 reporting this.
2454 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2455 Solaris, in the configure script automatically.
2456 * build system, tcpconns plugin: Check for `kvm_nlist' and
2457 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2458 library with similar functions to the BSD variant, but doesn't
2459 provide these necessary functions.
2460 * collectd.conf(5): Various fixes and clarifications.
2461 * collectd: Remove a GNUism (unnamed unions), thus improving
2462 portability.
2463 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
2464 This solves portability problems, especially for Solaris.
2465 * dns plugin: Fix a portability problem with NetBSD.
2466 * filecount plugin: Fix an off-by-one error. This error may cause a
2467 segmentation fault.
2468 * network plugin: Fix the handling of `type' in the network protocol.
2469 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2470 much larger buffer. This caused the `type' to be transferred much
2471 more often than necessary. In some cases, e. g. the `cpu' and
2472 `cpufreq' plugins being used at the same time, data may be corrupted
2473 in those files. Thanks to Bruno Prémont for debugging and reporting
2474 this issue.
2475 * processes plugin: Fix a possible segmentation fault when specifying
2476 invalid configuration options.
2477 * unixsock plugin: Make sure the initialization function is run only
2478 once. This resolves a file descriptor leak under systems which run
2479 the initialization more than once, such as Solaris.
2481 2008-10-16, Version 4.5.1
2482 * build system: Change `--enable-<plugin>' to abort with an error if
2483 dependencies are not met. Thanks to Bruno Prémont for the patch.
2484 Also, the poisoning of various string functions has been restricted
2485 to debug builds.
2486 * collectd: Fix a memory leak in the global value cache. With every
2487 *missing* value a couple of bytes would be leaked. Another memory
2488 leak in the configuration handling code has been fixed. Thanks to
2489 Niraj Tolia for reporting these issues.
2490 * collectd: Fix an off-by-one error in the ignorelist functionality.
2491 When using regular expressions, the last character would be missing,
2492 possibly matching differently from what one would expect.
2493 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2494 problem.
2495 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2496 Linzberger for reporting the bug.
2497 * iptables plugin: Fix an off-by-one error. If a string was just one
2498 character too long, it was truncated instead of reporting an error.
2499 * network plugin: Fix a memory leak in the configuration handling
2500 code. Thanks to Niraj Tolia for reporting this issue.
2501 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2502 * postgresql plugin: Don't reopen connection during reinitialization.
2503 This fixes a bug under Solaris and potentially other platforms.
2504 Missing calls to `PQclear' have been added, too. This fixes memory
2505 leaks. Thanks to ``Admin'' for reporting these bugs.
2506 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2507 library.
2508 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2509 problems with some `libc's. Thanks to Matthias Lay for reporting the
2510 bug.
2512 2008-09-04, Version 4.5.0
2513 * collectd: Added the ability to flush certain identifiers.
2514 * collectd: The concept of `notification meta data' has been
2515 introduced.
2516 * filecount plugin: The new filecount plugin counts the number of
2517 files in a directory and its subdirectories.
2518 * ipmi plugin: Sensor names have been changed to ensure unique names.
2519 Notifications upon added and removed sensors can now be generated.
2520 * notify_desktop plugin: This new plugin sends notifications to the
2521 X desktop using the structure defined in the `Desktop Notification
2522 Specification'.
2523 * notify_email plugin: This new plugin sends out notifications via
2524 email, using the `esmtp' library.
2525 * onewire plugin: The new experimental(!) onewire plugin reads values,
2526 such as temperatures, from sensors connected to the computer via the
2527 onewire bus.
2528 * perl plugin: Improved synchronized access to internal data structures
2529 and fixed a possible dead-lock.
2530 * perl plugin: Added the ability to flush certain identifiers and marked
2531 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2532 plugin_flush().
2533 * perl plugin: Added the ability to configure Perl plugins.
2534 * postgresql plugin: The new postgresql plugin collects statistics
2535 about or from a PostgreSQL database.
2536 * processes plugin: The `ProcessMatch' option has been added.
2537 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2538 IO load.
2539 * tcpconns plugin: This plugin has been ported to OpenBSD.
2540 * thermal plugin: The new thermal plugin collects system temperatures
2541 using Linux ACPI thermal zone data.
2543 2009-01-02, Version 4.4.5
2544 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2545 file may be in both locations, especially when the database was
2546 installed in a non-standard path. Thanks to Dusty Doris for
2547 reporting this.
2548 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2549 Solaris, in the configure script automatically.
2550 * collectd.conf(5): Various fixes and clarifications.
2551 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2552 portability problems, especially for Solaris.
2553 * dns plugin: Fix a portability problem with NetBSD.
2554 * network plugin: Fix the handling of `type' in the network protocol.
2555 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2556 much larger buffer. This caused the `type' to be transferred much
2557 more often than necessary. In some cases, e. g. the `cpu' and
2558 `cpufreq' plugins being used at the same time, data may be corrupted
2559 in those files. Thanks to Bruno Prémont for debugging and reporting
2560 this issue.
2561 * unixsock plugin: Make sure the initialization function is run only
2562 once. This resolves a file descriptor leak under systems which run
2563 the initialization more than once, such as Solaris.
2565 2008-10-16, Version 4.4.4
2566 * build system: Change `--enable-<plugin>' to abort with an error if
2567 dependencies are not met. Thanks to Bruno Prémont for the patch.
2568 Also, the poisoning of various string functions has been restricted
2569 to debug builds.
2570 * collectd: Fix a memory leak in the global value cache. With every
2571 *missing* value a couple of bytes would be leaked. Another memory
2572 leak in the configuration handling code has been fixed. Thanks to
2573 Niraj Tolia for reporting these issues.
2574 * collectd: Fix an off-by-one error in the ignorelist functionality.
2575 When using regular expressions, the last character would be missing,
2576 possibly matching differently from what one would expect.
2577 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2578 problem.
2579 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2580 Linzberger for reporting the bug.
2581 * network plugin: Fix a memory leak in the configuration handling
2582 code. Thanks to Niraj Tolia for reporting this issue.
2583 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2584 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2585 problems with some `libc's. Thanks to Matthias Lay for reporting the
2586 bug.
2588 2008-09-01, Version 4.4.3
2589 * collectd: Fix a memory leak in the threshold checking code.

2593 * snmp plugin: Fix a possible memory leak.
2595 2008-07-15, Version 4.4.2
2596 * build system: Use pkg-config to detect the upsclient library.
2597 * collectd: Try even harder to determine the endianness of the
2598 architecture collectd is being built on.
2599 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2600 of disks.
2601 * dns plugin: Fix compilation errors with BIND versions 19991001
2602 through 19991005.
2603 * network plugin: Bugfix in the init routine: The init function
2604 cleared a buffer regardless of its contents. This could lead to lost
2605 values under Solaris.
2606 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2607 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2608 function.
2609 * wireless plugin: Work around incorrect noise and power values
2610 returned by some broken drivers.
2612 2008-06-03, Version 4.4.1

2616 threshold checking.
2617 * collectd-nagios: Fix the protocol used to communicate with the
2618 daemon.
2619 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2620 initialization has errors. An issue with Perl 5.10 has been fixed.
2621 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2622 René Rebe and Siegmund Gorr for reporting this.
2624 2008-05-06, Version 4.4.0
2625 * collectd: Internal code cleanups.
2626 * collectd: Added support for a `Flush' command in the unixsock and
2627 exec plugins. This command can be used to force a plugin (or all) to
2628 flush its values to disk.
2629 * collectd: Thresholds can now be configured to apply to one data
2630 source only, making it possible to configure different thresholds
2631 for each data source.
2632 * apache, nginx plugins: Added the possibility to disable host and/or
2633 peer verification.
2634 * ascent plugin: The new ascent plugin reads and parses the statistics
2635 page of an Ascent server.
2636 * cpu plugin: Support for the statgrab library has been added.
2637 * disk plugin: The possibility to ignore certain disks or collect only
2638 specific disks has been added.
2639 * disk plugin: Support for the statgrab library has been added.
2640 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
2641 sensor values via IPMI, the intelligent platform management
2642 interface.
2643 * iptables plugin: The iptc library that is used by the iptables
2644 plugin has been added to the distribution, because it is not
2645 provided by all distributions and removed from at least one.
2646 * powerdns plugin: The new powerdns plugin reads statistics from an
2647 authoritative or a recursing PowerDNS name server.
2648 * rrdtool plugin: The size of the files generated with the default
2649 configuration has been decreased.
2650 * tail plugin: The new tail plugin can be used to gather statistics by
2651 continuously reading from log files.
2652 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2653 TeamSpeak2 server and collects statistics about the number of users
2654 and number of channels.
2655 * users plugin: Support for the statgrab library has been added.
2656 * vmem plugin: The new vmem plugin collects very detailed statistics
2657 about the virtual memory subsystem of Linux.
2659 2008-08-30, Version 4.3.4
2660 * Build system: Improved detection of and linking with the statgrab
2661 library.
2662 * collectd: Portability fixes, especially to determine endianness more
2663 reliable.
2664 * Various plugins: Fix format strings.
2665 * disk plugin: A fix for giving disks under Linux 2.4 the right names
2666 again has been applied.
2667 * memcached plugin: Fix a too short timeout and a related file
2668 descriptor leak.
2669 * memory plugin: A typo in the libstatgrab code has been fixed.
2670 * network plugin: A fix in the initialization function solves problems
2671 under Solaris.
2672 * nginx plugin: A thread-unsafe function has been replaced.
2673 * vserver plugin: A thread-unsafe function has been replaced.
2674 * wireless plugin: A work-around for broken wireless drivers has been
2675 added.
2677 2008-04-22, Version 4.3.3
2678 * build system: Improved detection of several libraries, especially if
2679 they are in non-standard paths.
2680 * build system: Portability fixes: Automatically define "_REENTRANT"
2681 if the libc expects it.
2682 * collectd: Error and warning messages have been improved.
2683 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2684 using them.
2685 * apache plugin: Allocate new memory when reading a webpage instead of
2686 using a buffer of static size.
2687 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2688 the program.
2689 * hddtemp plugin: Error and warning messages have been improved.
2690 * sensors plugin: Fix sensor collection for some chip types.
2692 2008-03-29, Version 4.3.2
2693 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2694 `Persist' threshold options.
2695 * collectd: Fix handling of missing values in the global value cache.
2696 * collectd: Improved error messages when parsing the configuration.
2697 * sensors plugin: Fix temperature collection with libsensors4.
2698 * unixsock plugin: Fix mixed input and output operation on streams.
2699 * wireless plugin: Fix reading noise value.
2701 2008-03-05, Version 4.3.1
2702 * exec plugin: Set supplementary group IDs.
2703 * network plugin:
2704 + Use `memcpy' when constructing/parsing a package to avoid
2705 alignment problems on weird architectures, such as Sparc.
2706 + Translate doubles to/from the x86 byte representation to ensure
2707 cross-platform compatibility.
2708 * ping plugin: Correct the handling of the `TTL' setting.
2709 * swap plugin: Reapply a patch for Solaris.
2710 * tcpconns plugin: Portability improvements.
2712 2008-02-18, Version 4.3.0
2713 * collectd: Notifications have been added to the daemon. Notifications
2714 are status messages that may be associated with a data instance.
2715 * collectd: Threshold checking has been added to the daemon. This
2716 means that you can configure threshold values for each data
2717 instance. If this threshold is exceeded a notification will be
2718 created.
2719 * collectd: The new `FQDNLookup' option tells the daemon to use the
2720 full qualified domain name as the hostname, not just the host part
2721 es returned by `gethostname(2)'.
2722 * collectd: Support for more than one `TypesDB' file has been added.
2723 This is useful when one such file is included in a package but one
2724 wants to add custom type definitions.
2725 * collectd: The `Include' config option has been expanded to handle
2726 entire directories and shell wildcards.
2727 * collectdmon: The new `collectdmon' binary detects when collectd
2728 terminates and automatically restarts it again.
2729 * csv plugin: The CSV plugin is now able to store counter values as a
2730 rate, using the `StoreRates' configuration option.
2731 * exec plugin: Handling of notifications has been added and the
2732 ability to pass arguments to the executed programs has been added.
2733 * hddtemp plugin: The new `TranslateDevicename' option lets you
2734 disable the translation from device names to major-minor-numbers.
2735 * logfile plugin: Handling of notifications has been added.
2736 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2737 domain name lookups in this plugin.
2738 * perl plugin: Many internal changes added support for handling multiple
2739 threads making the plugin reasonably usable inside collectd. The API has
2740 been extended to support notifications and export global variables to
2741 Perl plugins; callbacks now have to be identified by name rather than a
2742 pointer to a subroutine. The plugin is no longer experimental.
2743 * uuid plugin: The new UUID plugin sets the hostname to an unique
2744 identifier for this host. This is meant for setups where each client
2745 may migrate to another physical host, possibly going through one or
2746 more name changes in the process. Thanks to Richard Jones from
2747 Red Hat's Emerging Technology group for this plugin.
2748 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2749 CPU, disk and network statistics about guest systems on the same
2750 physical server. Thanks to Richard Jones from Red Hat's Emerging
2751 Technology group for this plugin.
2753 2008-04-22, Version 4.2.7
2754 * build system: Improved detection of several libraries, especially if
2755 they are in non-standard paths.
2756 * build system: Portability fixes: Automatically define "_REENTRANT"
2757 if the libc expects it.
2758 * collectd: Error and warning messages have been improved.
2759 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2760 using them.
2761 * apache plugin: Allocate new memory when reading a webpage instead of
2762 using a buffer of static size.
2763 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2764 the program.
2765 * hddtemp plugin: Error and warning messages have been improved.
2766 * sensors plugin: Fix sensor collection for some chip types.
2768 2008-03-29, Version 4.2.6
2769 * collectd: Improved error messages when parsing the configuration.
2770 * sensors plugin: Fix temperature collection with libsensors4.
2771 * unixsock plugin: Fix mixed input and output operation on streams.
2772 * wireless plugin: Fix reading noise value.
2774 2008-03-04, Version 4.2.5
2775 * apache plugin: Improved initialization and error messages.
2776 * exec plugin: Set supplementary group IDs.
2777 * network plugin:
2778 + Create separate threads for reading from the socket and parsing
2779 and dispatching incoming packets. Versions prior to this may have
2780 problems in high-load situations, where the socket receive buffers
2781 overflows, resulting in gaps in the data.
2782 + Use `memcpy' when constructing/parsing a package to avoid
2783 alignment problems on weird architectures, such as Sparc.
2784 + Translate doubles to/from the x86 byte representation to ensure
2785 cross-platform compatibility.
2786 * ping plugin: Correct the handling of the `TTL' setting.
2787 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2788 * swap plugin: Reapply a patch for Solaris.
2789 * tcpconns plugin: Portability improvements.
2791 2008-01-21, Version 4.2.4
2792 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2793 the permission on the socket as documented in the manpage. Thanks to
2794 Evgeny Chukreev for fixing this issue.
2795 * collectd: The documentation has been improved.
2797 2007-12-28, Version 4.2.3
2798 * sensors plugin: Updated the plugin to build and work with version 3
2799 of the libsensors library.
2801 2007-12-15, Version 4.2.2
2802 * nginx plugin: Incorrect comparison of strings lead to a segfault
2803 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2804 this.
2805 * logfile plugin: The config option `Timestamp' was handled
2806 incorrectly and basically always active. Thanks to Luke Heberling
2807 for fixing this.
2809 2007-11-08, Version 4.2.1
2810 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2811 enabled on the host.
2812 * snmp plugin: Fix a memory leak.
2814 2007-10-27, Version 4.2.0
2815 * collectd: The new config option `Include' lets you include other
2816 configfiles and thus split up your config into smaller parts. This
2817 may be especially interesting for the snmp plugin to keep the data
2818 definitions separate from the host definitions.
2819 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2820 (number of connections, octets and packets for each service and
2821 destination). Thanks to Sebastian Harl for this plugin.
2822 * memcached plugin: The new `memcached' plugin connects to a memcached
2823 daemon process and collects statistics of this distributed caching
2824 system. Thanks to Antony Dovgal for contributing this plugin.
2825 * nginx plugin: The new `nginx' plugin reads the status page of an
2826 nginx daemon and saves the handled connections and requests.
2827 * perl plugin: Many changes, including the added `EnableDebugger'
2828 config option which lets you debug your Perl plugins more easily.
2829 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2830 be more thread-safe otherwise by locking calls to the library.
2831 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2832 correct the values returned by SNMP-agents. If a <data> block is
2833 defined as `table' the instance is now optional. The sequence number
2834 is used as the type-instance in this case. The new `InstancePrefix'
2835 option allows to add arbitrary prefixes to the type-instance.
2836 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2837 certain TCP connections and what state they're in. This can be used
2838 to see how many connections your FTP server has to handle or how
2839 many outgoing connections your mailserver has open.
2841 2008-01-11, Version 4.1.6
2842 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2843 the permission on the socket as documented in the manpage. Thanks to
2844 Evgeny Chukreev for fixing this issue.
2845 * collectd: The documentation has been improved.
2847 2007-12-27, Version 4.1.5
2848 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
2849 memory situations.
2850 * sensors plugin: Updated the plugin to build and work with version 3
2851 of the libsensors library.
2853 2007-11-08, Version 4.1.4
2854 * Build system: Improve detection of the rrd library, especially if
2855 it's in a non-standard location.
2856 * Build system: A bug when parsing the argument for
2857 `--with-libnetsnmp' has been fixed.
2858 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2859 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2860 a deadlock or delay when shutting down the daemon.
2861 * snmp plugin: Fix a memory leak.
2863 2007-10-24, Version 4.1.3
2864 * collectd: A build issue under Solaris has been resolved by renaming
2865 data types.
2866 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2867 be more thread-safe otherwise by locking calls to the library.
2869 2007-09-28, Version 4.1.2
2870 * apcups plugin: Fix reporting of the `load percent' data.
2871 * wireless plugin: Correct the handling of cards returning signal and
2872 noise quality as percentage.
2873 * perl plugin: Fix a possible buffer overflow in get_module_name().
2874 * build system: Further improve the detection of libraries.
2875 * netlink plugin: Build issues under some older versions of the Linux
2876 includes (i. e. Debian Sarge) have been fixed.
2877 * snmp plugin: Fix a potential segfault when a host times out. Add
2878 support for the `timeticks' type.
2880 2007-09-12, Version 4.1.1
2881 * Build system: The detection of `libnetlink' has been improved.
2882 * collectd: The documentation has been fixed in numerous places.
2883 * exec plugin: Setting the group under which to run a program has been
2884 fixed.
2885 * collectd: The `sstrerror' function was improved to work correctly
2886 with the broken GNU version of `strerror_r'.
2887 * collectd: Write an error message to STDERR when loading of a plugin
2888 fails.
2889 * apcups plugin: Fix the `types' used to submit the values: They still
2890 has an `apcups_' prefix which doesn't work anymore.
2891 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2892 whatever the client thinks is `now'..
2894 2007-09-01, Version 4.1.0
2895 * Build system: The build system has been changed to automatically
2896 disable all plugins, which are missing dependencies. The dependency
2897 checking has been removed from the plugins themselves to remove
2898 redundancy.
2899 * Flexible interval: The interval of collected data is now sent along
2900 with the data itself over the network, so that the interval-settings
2901 of server and clients no longer needs to match.
2902 * netlink plugin: The new `netlink' plugin connects to the Linux
2903 kernel using a netlink socket and uses it to query information about
2904 interfaces, qdiscs and classes.
2905 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2906 to not block data collection.
2907 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2908 network devices, such as switches, routers, thermometers, rack
2909 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2910 plugin.
2911 * unixsock plugin: Added the `LISTVAL' command.
2912 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2913 of music played with xmms.
2915 2007-09-28, Version 4.0.9
2916 * apcups plugin: Fix reporting of the `load percent' data.
2917 * wireless plugin: Correct the handling of cards returning signal and
2918 noise quality as percentage.
2919 * perl plugin: Fix a possible buffer overflow in get_module_name().
2921 2007-09-12, Version 4.0.8
2922 * collectd: The `sstrerror' function was improved to work correctly
2923 with the broken GNU version of `strerror_r'.
2924 * collectd: Write an error message to STDERR when loading of a plugin
2925 fails.
2926 * apcups plugin: Fix the `types' used to submit the values: They still
2927 has an `apcups_' prefix which doesn't work anymore.
2928 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2929 whatever the client thinks is `now'..
2931 2007-08-26, Version 4.0.7
2932 * documentation: Some typos have been fixed and some information has
2933 been improved.
2934 * build system: Many fixes for detecting libraries in unusual places,
2935 such as on RedHat systems. The affected libraries are `libcurl',
2936 `libmysql', and `libupsclient'.
2937 * network plugin: Allow the `Port' option to be specified as a number
2938 (i. e. without quotes).
2939 * nut plugin: A fix allows linking the nut plugin against
2940 libupsclient, version >= 2.2.0.
2941 * processes plugin: Fix a potential segmentation fault.
2943 2007-07-30, Version 4.0.6
2944 * sensors plugin: Fix the ignorelist functionality: Only the `type
2945 instance' was used to match against the list, but the documentation
2946 told otherwise. This release fixes the code, so it complies with the
2947 documentation.
2948 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2949 configuration messages will end up in the logging facility.
2950 * conrtib/fedora: The contributed specfile for Fedora has been
2951 updated.
2953 2007-07-05, Version 4.0.5
2954 * Portability: More fixes for OpenBSD have been included.
2956 2007-06-24, Version 4.0.4
2957 * cpu plugin: Fixed the Solaris code.

2959 * interface plugin: Fixed the Solaris code.
2960 * load plugin: Fixed the alternative `/proc' Linux code.
2961 * memory plugin: Fixed the Solaris code.
2962 * oconfig: Don't require `-lfl' anymore.
2964 2007-06-19, Version 4.0.3
2965 * cpu plugin: Fix the Darwin / Mac OS X code.
2966 * ping plugin: Use the return value of `getpid', not its address.
2967 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2968 initialized correctly.
2969 * configure: Added `--with-nan-emulation' to aid cross compilation.
2971 2007-06-12, Version 4.0.2
2972 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2973 they're given in numerically form.
2975 2007-06-07, Version 4.0.1
2976 * iptables plugin: A bug in the configuration routine has been fixed.
2977 Setting a comment in the configfile will no longer cause a
2978 segmentation fault.
2980 2007-06-03, Version 4.0.0
2981 * collectd: The plugin-infrastructure has been changed to allow for
2982 more types of plugins, namely `write' and `log' plugins.
2983 * collectd: The read-function has been changed to read many plugins in
2984 parallel, using threads. Thus, plugins generally need to use
2985 thread-safe functions from now on.
2986 * collectd: The '-t' command line options allows to perform syntax tests
2987 of the configuration file and exit immediately.
2988 * csv plugin: The new `csv' plugin handles output to `comma separated
2989 values'-files.
2990 * rrdtool plugin: The new `rrdtool' plugin handles output to
2991 RRD-files. Data can be cached to combine multiple updates into one
2992 write to increase IO-performance.
2993 * network plugin: The new `network' plugin handles IO via the network.
2994 It implements a different, much more extensible protocol which can
2995 combine many values in one packet, decreasing the number of UDP-
2996 packets being sent. It can read from and send to the network and
2997 with the appropriate configuration even forward packets to other
2998 networks.
2999 * unixsock plugin: The new `unixsock' plugin provides an interface to
3000 communicate with the daemon while it is running. Right now the
3001 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3002 come.
3003 * perl plugin: The new `perl' plugin allows you to write extensions
3004 for collectd in the scripting-language Perl.
3005 * logfile plugin: The new `logfile' plugin writes logmessages to files
3006 or STDOUT or STDERR.
3007 * syslog plugin: The new `syslog' plugin sends logmessages to the
3008 system's syslog daemon.
3009 * entropy plugin: The new `entropy' plugin collects the amount of
3010 entropy currently being available to the system.
3011 * exec plugin: The new `exec' plugin forks child processes and reads
3012 back values provided by the forked processes.
3013 * iptables plugin: The new `iptables' plugin reads counters from
3014 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3015 plugin.
3016 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3017 to Peter Holik for contributing this plugin.
3018 * nut plugin: The new `nut' plugin connects the upsd of the `network
3019 ups tools' and reads information about the connected UPS.
3020 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3021 connections) field was added by Florent Monbillard.
3022 * collectd-nagios: The new `collectd-nagios' binary queries values
3023 from collectd, parses them and exits according to Nagios-standards.
3024 * manpages: The manpages have been improved a lot.
3026 2007-09-28, Version 3.11.7
3027 * wireless plugin: Correct the handling of cards returning signal and
3028 noise quality as percentage.
3030 2007-08-31, Version 3.11.6
3031 * processes plugin: Fix a potential segmentation fault.
3033 2007-05-29, Version 3.11.5
3034 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3035 * ntpd plugin: Fix a potential buffer overflow.
3036 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3037 were accounted as `zombies'.
3039 2007-04-10, Version 3.11.4
3040 * dns plugin: Change the order of includes to make the plugin compile
3041 under FreeBSD.
3043 2007-03-30, Version 3.11.3
3044 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3045 of the unused `COLLECT_KSTAT'.
3047 2007-02-11, Version 3.11.2
3048 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3049 NULL-pointer may have been passed to `printf' which causes a
3050 segfault with some libcs.
3052 2007-02-10, Version 3.11.1
3053 * df plugin: Some wrong defines have been fixed so the plugin works
3054 under Solaris again.
3055 * dns plugin: The usage of a struct has been fixed to work with
3056 non-GNU libcs.
3057 * processes plugin: Some missing defines have been added so the plugin
3058 compiles cleanly under FreeBSD and presumably other UNIXes.
3060 2006-12-22, Version 3.11.0
3061 * collectd: The new command line option `-P' makes it easier for
3062 distributors to change the location of PID-files.
3063 * collectd: The daemon shuts down faster now which makes it easier to
3064 write init.d-scripts for it.
3065 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3066 caused problems every now and then.
3067 * df plugin: New config options allow to ignore certain mountpoints,
3068 filesystem types or devices.
3069 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3070 and interprets it. It collects traffic as well as qtype, opcode and
3071 rcode counts.
3072 * email plugin: Sebastian Harl has contributed this plugin which
3073 counts received mails in categories (e. g. ham, spam, virus), spam
3074 score (as given by SpamAssassin) and check types.
3075 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3076 uses `mbmon' to gather information from sensors on the motherboard.
3077 * processes plugin: Collect detailed statistics for configured
3078 processes, that's process and thread count, CPU usage, resident
3079 segment size and pagefaults.
3080 * multimeter plugin: Peter Holik contributed a new plugin which
3081 queries multimeters.
3082 * sensors plugin: Lubos Stanek has put much effort into improving this
3083 plugin, including `extended naming', collection of voltage values
3084 and the possibility to ignore certain values.
3086 2006-12-21, Version 3.10.4
3087 * Max Kellermann has identified a bug in the server routine: When
3088 opening a socket fails the daemon will (re)try opening the socket in
3089 an endless loop, ultimately leading to a `EMFILE' error.
3091 2006-11-04, Version 3.10.3
3092 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3093 ntpd's reply was sent in more than one packet, the buffer size was
3094 calculated incorrectly, resulting in the reading of uninitialized or
3095 freed memory.
3097 2006-11-01, Version 3.10.2
3098 * The sample config file has been improved.
3099 * Errors in the manpages have been corrected.
3100 * The ping-plugin now adds hosts during initialization, not during
3101 startup. This speeds up startup when no network connectivity is
3102 available. Also, the hosts are being added later when the network is
3103 available.
3104 * Improved BSD-support for the df-plugin.
3105 * Fixed syntax errors in the swap-plugin for Mac OS X.
3106 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3107 plugin.
3108 * Don't disable the mysql-plugin if connecting to the database fails
3109 during initialization. Instead, try again in increasing intervals.
3111 2006-07-19, Version 3.10.1
3112 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3113 the apcups cannot be reached, unconnected sockets will pile up and
3114 eventually lead to `Too many open files' errors.
3116 2006-07-09, Version 3.10.0
3117 * The `disk' plugin has been ported to Darwin.
3118 * The `battery' plugin should work on many Apple computers now.
3119 * The `traffic' plugin can now ignore certain interfaces. Also,
3120 statistics for sent/received packets and errors have been added.
3121 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3122 to Anthony Gialluca for contributing this plugin and providing me
3123 with a test environment :)
3124 * A plugin for monitoring an NTP instance and the local clock drift
3125 has been added.
3127 2006-06-25, Version 3.9.4
3128 * The Solaris code in the `swap' plugin has been changed to reflect
3129 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3130 working this out.
3131 * The debugging system has been fixed to work with the Sun libc.
3132 * When built without librrd the variable `operating_mode' could be
3133 uninitialized. Thanks to David Elliot for reporting the bug.
3135 2006-06-01, Version 3.9.3
3136 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3137 operating systems also profit from the changes, but I wasn't able to
3138 check that.
3139 * Changed the build system to find the netinet-includes under FreeBSD
3140 and therefore successfully build the `liboping' library there.
3142 2006-05-09, Version 3.9.2
3143 * Applied a patch to the `liboping' library. Due to a bug in the
3144 sequence checking the `ping' plugin stopped working after
3145 approximately 7.6 days.
3147 2006-05-09, Version 3.8.5
3148 * Applied a patch to the `liboping' library. Due to a bug in the
3149 sequence checking the `ping' plugin stopped working after
3150 approximately 7.6 days.
3152 2006-04-21, Version 3.9.1
3153 * Build issues with Solaris and possible other architectures have been
3154 resolved.
3155 * Problems when building the `apache'-plugin without `libcurl' have
3156 been resolved.
3157 * A bug in the `ping' plugin has been fixed. Sorry folks.
3159 2006-04-02, Version 3.9.0
3160 * A plugin to monitor the Apache webserver has been added.
3161 <http://httpd.apache.org/>
3162 * A plugin to collect statistics about virtual servers using VServer.
3163 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3164 this plugin :)
3165 * A plugin for wireless LAN cards has been added. It monitors signal
3166 strength, link quality and noise ratio..
3167 * A plugin for Apple hardware sensors has been added.
3168 * An option to compile collectd with different `step' and `heartbeat'
3169 settings has been added. The size of RRAs is no longer static but
3170 calculated based on the settings for `step' and `width'.
3171 * The `ping' plugin can now be configured to use a certain TTL.
3172 * A plugin to monitor the hardware sensors of Apple computers has been
3173 added.
3174 * The plugins `cpu', `memory', `processes' and `traffic' have been
3175 ported to Mach/Darwin (Mac OS X).
3176 * The `log mode' has been contributed by Christophe Kalt. It writes
3177 the data into text files rather than RRD files.
3179 2006-04-09, Version 3.8.4
3180 * Applied patch by Vincent Stehlé which improves the disk-name
3181 resolution in the `hddtemp' plugin for Linux systems.
3183 2006-04-02, Version 3.8.3
3184 * Applied a patch by James Byers: The MySQL plugin was not working
3185 with MySQL 5.0.2 or later.
3187 2006-03-14, Version 3.8.2
3188 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3189 the GNU libc, because it points to `/etc/fstab' rather than
3190 `/etc/mtab'.
3192 2006-03-13, Version 3.8.1
3193 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3194 * Fixes in the debian `postinst' and `init.d' scripts.
3196 2006-03-09, Version 3.8.0
3197 * The `ping' plugin no longer uses `libping' but a self written
3198 library named `liboping'. With this library it's possible to ping
3199 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3201 2006-02-18, Version 3.7.2
3202 * A simple bug in the `battery' plugin has been fixed. It should now
3203 work with ACPI based batteries as well. Thanks to Sebastian for
3204 fixing this.
3205 * Fixing a bug that prevented collectd to be built without librrd.
3206 Thanks to Werner Heuser for reporting it.
3208 2006-02-04, Version 3.7.1
3209 * The new network code has been improved to build with older versions
3210 of glibc.
3211 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3212 to Tommie Gannert for this patch.
3214 2006-01-30, Version 3.7.0
3215 * The `battery' plugin has been added. It collects information about
3216 laptop batteries..
3217 * The MySQL plugin has been improved: It now writes two more RRD
3218 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3219 * The `cpufreq' plugin now reads another file since the file it did
3220 read so far causes much overhead in the kernel. Also, you need root
3221 to read the old file, but not to read the new one.
3222 * The `hddtemp' plugin can now be configured to connect to another
3223 address and/or port than localhost.
3224 * The `df' plugin now prefers `statvfs' over `statfs'.
3225 * The network code has been rewritten. collectd now supports unicast
3226 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3227 be set in the configfile.
3229 2006-01-24, Version 3.6.2
3230 * Due to a bug in the configfile handling collectd wouldn't start in
3231 client mode. This released fixes this.
3233 2006-01-20, Version 3.6.1
3234 * Due to a bug in `configure.in' all modules and the binary were
3235 linked against `libmysqlclient'. This issue is solved by this
3236 release.
3238 2006-01-17, Version 3.6.0
3239 * A config file has been added. This allows for loading only specific
3240 plugins.
3241 * A `df' plugin has been added.
3242 * A `mysql' plugin has been added.
3243 * The `ping' plugin doesn't entirely give up hope when a socket error
3244 occurred, but will back of and increase the intervals between tries.
3246 2006-01-21, Version 3.5.2
3247 * Fixed yet another bug in the signal handling.. Stupid typo..
3248 * Improved the ping plugin to not give up on socket errors (backport
3249 from 3.6.0).
3251 2005-12-18, Version 3.5.1
3252 * The PID-file is now deleted correctly when shutting down the daemon.
3253 * SIGINT and SIGTERM are now handled correctly.
3255 2005-12-16, Version 3.5.0 (Revision 326)
3256 * A bug in the `load' module under Solaris has been fixed.
3257 * The `users' module has been contributed by Sebastian Harl. It counts
3258 currently logged in users.
3259 * The CPU module now works under FreeBSD without the use of
3260 `libstatgrab', however SMP support is missing.
3261 * The default directories for the RRD files and the PID file now
3262 depend on the compile time setting of `localstatedir'.
3264 2005-11-15, Version 3.4.0 (Revision 236)
3265 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3266 from gentoo's bugzilla for writing the patch.
3267 * The build dependency for librrd has been removed. Binaries built
3268 without librrd are client-only and will multicast their value as
3269 with the `-c' argument.
3270 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3271 * The newly introduced `-f' switch prevents daemon initialization
3272 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3273 Barcellos for this patch.
3275 2005-11-04, Version 3.3.0 (Revision 216)
3276 * New modules have been added:
3277 - `serial', for monitoring traffic on the serial interfaces
3278 - `nfs', for graphing NFS procedure calls
3279 - `tape', traffic from/to tape devices
3280 * The memory.rrd now accepts more than 4Gig of memory.
3282 2005-10-26, Version 3.2.0 (Revision 200)
3283 * Support for graphing the processes has been added (thanks to Lyonel
3284 Vincent)
3285 * If reading from hddtemp fails collectd will increase the time
3286 between polls up to one day.
3287 * The init.d files have been improved.
3288 * Problems with the spec file have been fixed.
3290 2005-10-16, Version 3.1.0 (Revision 194)
3291 * Added the `setsid' syscall to the startup code.
3292 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3294 2005-09-30, Version 3.0.0 (Revision 184)
3295 * The ability to send/receive data to/from the network (think
3296 multicast) has been added.
3297 * Modules have been split up into shared libraries can be loaded at
3298 runtime. The biggest advantage is that the core program doesn't need
3299 to be linked against an external library.
3300 * A patch by George Kargiotakis has been applied: It fixes the sensors
3301 behaviour then more than one sensor is being queried.
3303 2005-09-16, Version 2.1.0 (Revision 172)
3304 * A module for swap statistics has been added.
3306 2005-09-09, Version 2.0.0 (Revision 135)
3307 * Filenames can no longer be configured at program startup. The only
3308 options as of this version are the directory and ping hosts.
3309 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3310 Soft-IRQ statistics are added to `System'.
3311 * Diskstats now collect read and write bytes, not sectors.
3312 * Ping statistics can now be collected for more than one host. There
3313 is no default any more: If no host is given no host will be pinged.
3314 * A self-written patch for libping has been applied so it builds
3315 cleanly.
3317 2005-09-01, Version 1.8.1 (Revision 123)
3318 * Much improved configure-script: libraries and features may now be
3319 disabled.
3320 * More detailed warnings/error messages when RRD update fails.
3322 2005-08-29, Version 1.8.0:
3323 * Support for collecting disk statistics under Solaris.
3325 2005-08-25, Version 1.7.0:
3326 * Support for libstatgrab[1] for load, memory usage and network
3327 traffic. CPU- and disk-usage are not (yet) supported, since
3328 libstatgrab returns insufficient information. I will contact the
3329 authors.
3330 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3331 aren't necessarily counted linear which is now handled correctly.
3332 [1]: http://www.i-scream.org/libstatgrab/
3334 2005-08-21, Version 1.6.0:
3335 * Basic support for Solaris: System load and cpu-usage can be
3336 collected under Solaris, too. Other stats will follow later.
3337 * Many fixes in the autoconf-script
3338 * Collection/Museum scripts have been added under contrib/museum
3339 * collectd may now be started in unprivileged mode, though ping
3340 statistics will not work.
3342 2005-07-17, Version 1.5.1:
3343 * Diskstats-RRDs now use major/minor for naming. Some systems have
3344 weird strings as disk-names..
3346 2005-07-17, Version 1.5:
3347 * A new module, diskstats, has been added. It collects information
3348 about the disks and partitions.
3350 2005-07-11, Version 1.4.2:
3351 * The meminfo module has been changed to work with more platforms
3352 and/or kernel versions.
3354 2005-07-10, Version 1.4.1: Correct traffic stats
3355 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3356 forgot to correct when I changed that module.
3358 2005-07-09, Version 1.4: More traffic stats
3359 * Traffic is now collected for all interfaces that can be found
3360 * Temperature-statistics are read from lm-sensors if available
3362 2005-07-08, Version 1.3: CPU stats
3363 * Collecting CPU statistics now
3365 2005-07-12, Version 1.2: Using syslog
3366 * collectd is now using the syslog facility to report errors, warnings
3367 and the like..
3368 * The default directory is now /var/db/collectd
3370 2005-07-10, Version 1.1: Minor changes
3371 * Nothing really useful to say ;)
3373 2005-07-09, Version 1.0: Initial Version
3374 * The following modules are provided:
3375 * Load average
3376 * Ping time
3377 * Traffic
3378 * Memory info
