1862 code. Thanks to Sebastian Harl for the patch.
1863 * collectd: Remove old values when a cache entry is marked as missing.

1866 Díaz for the patch.
1867 * collectd: The “plugin_unregister_read” function has been fixed.
1868 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library

1908 first one prevented thresholds to be checked at all, the second one
1909 caused wrong behavior with the persistency option. Thanks to Andrés
1910 J. Díaz for fixing these problems.
1911 * collectd: Handling of the `Include' configuration option has been
1912 fixed.
1913 * rrdtool plugin: Make sure initialization is run only once. This
1914 resolves problems under Solaris and potentially other systems.
1915 Thanks to Amit Gupta for reporting this bug.
1916 * java plugin: Make it possible to use dots ('.') instead of slashes
1917 ('/') as the class separator. Thanks to Randy Rizun for pointing
1918 this out.

2025 name which prevented this match to be used as documented. Thanks to
2026 Bruno Prémont for finding this problem.
2027 * bind plugin: Fix collection of the cached RR sets. The number of RR
2028 sets currently in the cache was collected as a counter value, which
2029 is nonsense. Thanks to Bruno Prémont for implementing this.
2030 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2031 primarily BSDs, don't take it well and crash.
2032 * oracle plugin: Portability to 64 bit systems has been improved.
2033 * postgresql plugin: The default configuration has been improved.
2034 * rrdtool plugin: Fix a possible race condition: If the network plugin

2045 faults. Thanks to Peter Holik for his patch.
2047 2009-02-16, Version 4.6.0
2048 * collectd: Added the `filter chain' infrastructure, which allows the
2049 user to use `matches' and `targets' to control value processing.
2050 * collectd: The new `-T' command line argument allows more in-depth
2051 testing of a configuration. Thanks to Doug MacEachern for the patch.

2071 Kuhnle for the patch.
2072 * csv plugin: Make it possible to write values to STDOUT instead of
2073 files. This is meant for testing purposes mostly. The output written
2074 to STDOUT is compatible with the exec plugin. Thanks to Doug
2075 MacEachern for the patch.
2076 * curl plugin: This new plugin can be used to read web pages and parse
2077 them using the same mechanism that's used in the tail plugin.
2078 * dbi plugin: This new plugin allows you to connect to a variety of
2079 relational databases and use SQL to gather custom statistics from
2080 it. It is similar to the already existing PostgreSQL plugin but uses
2081 libdbi to communicate with the database(s).
2082 * interface plugin: Use the ignorelist framework when selecting /
2083 ignoring interfaces. This allows one to use regular expressions to
2084 select interfaces, too.

2103 allowing plugins to register `matches' and `targets'.
2104 * postgresql plugin: The preferred configuration syntax has been
2105 updated to be in line with the syntax used by the new dbi and oracle
2106 plugins. The compatibility code for the old syntax is present.
2107 Support for the new `Result' blocks and the interval parameter has
2108 been added.
2109 * processes plugin: Stacksize and virtual memory usage statistics have
2110 been added. Portability fixes.
2111 * rrdcached plugin: This new plugin uses the (still in development)
2112 RRD accelerator daemon, rrdcached. This daemon works very similar to
2113 the original rrdtool plugin of collectd, but adds some more nice
2114 features.
2115 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2116 added.
2118 2009-05-09, Version 4.5.4

2136 initialized, the daemon may crash.
2137 * memory plugin: Fix a potential problem under Solaris.
2139 2009-02-22, Version 4.5.3

2153 file may be in both locations, especially when the database was
2154 installed in a non-standard path. Thanks to Dusty Doris for
2155 reporting this.
2156 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2157 Solaris, in the configure script automatically.
2158 * build system, tcpconns plugin: Check for `kvm_nlist' and
2159 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2160 library with similar functions to the BSD variant, but doesn't
2161 provide these necessary functions.
2162 * collectd.conf(5): Various fixes and clarifications.
2163 * collectd: Remove a GNUism (unnamed unions), thus improving
2164 portability.
2165 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
2166 This solves portability problems, especially for Solaris.
2167 * dns plugin: Fix a portability problem with NetBSD.

2169 segmentation fault.
2170 * network plugin: Fix the handling of `type' in the network protocol.
2171 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2172 much larger buffer. This caused the `type' to be transferred much
2173 more often than necessary. In some cases, e. g. the `cpu' and
2174 `cpufreq' plugins being used at the same time, data may be corrupted
2175 in those files. Thanks to Bruno Prémont for debugging and reporting
2176 this issue.
2177 * processes plugin: Fix a possible segmentation fault when specifying
2178 invalid configuration options.
2179 * unixsock plugin: Make sure the initialization function is run only
2180 once. This resolves a file descriptor leak under systems which run
2181 the initialization more than once, such as Solaris.
2183 2008-10-16, Version 4.5.1
2184 * build system: Change `--enable-<plugin>' to abort with an error if
2185 dependencies are not met. Thanks to Bruno Prémont for the patch.
2186 Also, the poisoning of various string functions has been restricted
2187 to debug builds.
2188 * collectd: Fix a memory leak in the global value cache. With every
2189 *missing* value a couple of bytes would be leaked. Another memory
2190 leak in the configuration handling code has been fixed. Thanks to
2191 Niraj Tolia for reporting these issues.
2192 * collectd: Fix an off-by-one error in the ignorelist functionality.
2193 When using regular expressions, the last character would be missing,
2194 possibly matching differently from what one would expect.
2195 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2196 problem.
2197 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2198 Linzberger for reporting the bug.
2199 * iptables plugin: Fix an off-by-one error. If a string was just one
2200 character too long, it was truncated instead of reporting an error.
2201 * network plugin: Fix a memory leak in the configuration handling
2202 code. Thanks to Niraj Tolia for reporting this issue.
2203 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2204 * postgresql plugin: Don't reopen connection during reinitialization.
2205 This fixes a bug under Solaris and potentially other platforms.
2206 Missing calls to `PQclear' have been added, too. This fixes memory
2207 leaks. Thanks to ``Admin'' for reporting these bugs.
2208 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2209 library.
2210 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2211 problems with some `libc's. Thanks to Matthias Lay for reporting the
2212 bug.
2214 2008-09-04, Version 4.5.0
2215 * collectd: Added the ability to flush certain identifiers.
2216 * collectd: The concept of `notification meta data' has been
2217 introduced.
2218 * filecount plugin: The new filecount plugin counts the number of
2219 files in a directory and its subdirectories.
2220 * ipmi plugin: Sensor names have been changed to ensure unique names.
2221 Notifications upon added and removed sensors can now be generated.
2222 * notify_desktop plugin: This new plugin sends notifications to the
2223 X desktop using the structure defined in the `Desktop Notification
2224 Specification'.
2225 * notify_email plugin: This new plugin sends out notifications via
2226 email, using the `esmtp' library.
2227 * onewire plugin: The new experimental(!) onewire plugin reads values,
2228 such as temperatures, from sensors connected to the computer via the
2229 onewire bus.
2230 * perl plugin: Improved synchronized access to internal data structures
2231 and fixed a possible dead-lock.
2232 * perl plugin: Added the ability to flush certain identifiers and marked
2233 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2234 plugin_flush().
2235 * perl plugin: Added the ability to configure Perl plugins.
2236 * postgresql plugin: The new postgresql plugin collects statistics
2237 about or from a PostgreSQL database.
2238 * processes plugin: The `ProcessMatch' option has been added.
2239 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2240 IO load.
2241 * tcpconns plugin: This plugin has been ported to OpenBSD.
2242 * thermal plugin: The new thermal plugin collects system temperatures
2243 using Linux ACPI thermal zone data.
2245 2009-01-02, Version 4.4.5
2246 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2247 file may be in both locations, especially when the database was
2248 installed in a non-standard path. Thanks to Dusty Doris for
2249 reporting this.
2250 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2251 Solaris, in the configure script automatically.
2252 * collectd.conf(5): Various fixes and clarifications.
2253 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2254 portability problems, especially for Solaris.
2255 * dns plugin: Fix a portability problem with NetBSD.
2256 * network plugin: Fix the handling of `type' in the network protocol.
2257 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2258 much larger buffer. This caused the `type' to be transferred much
2259 more often than necessary. In some cases, e. g. the `cpu' and
2260 `cpufreq' plugins being used at the same time, data may be corrupted
2261 in those files. Thanks to Bruno Prémont for debugging and reporting
2262 this issue.
2263 * unixsock plugin: Make sure the initialization function is run only
2264 once. This resolves a file descriptor leak under systems which run
2265 the initialization more than once, such as Solaris.
2267 2008-10-16, Version 4.4.4
2268 * build system: Change `--enable-<plugin>' to abort with an error if
2269 dependencies are not met. Thanks to Bruno Prémont for the patch.
2270 Also, the poisoning of various string functions has been restricted
2271 to debug builds.
2272 * collectd: Fix a memory leak in the global value cache. With every
2273 *missing* value a couple of bytes would be leaked. Another memory
2274 leak in the configuration handling code has been fixed. Thanks to
2275 Niraj Tolia for reporting these issues.
2276 * collectd: Fix an off-by-one error in the ignorelist functionality.
2277 When using regular expressions, the last character would be missing,
2278 possibly matching differently from what one would expect.
2279 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2280 problem.
2281 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2282 Linzberger for reporting the bug.
2283 * network plugin: Fix a memory leak in the configuration handling
2284 code. Thanks to Niraj Tolia for reporting this issue.
2285 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2286 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2287 problems with some `libc's. Thanks to Matthias Lay for reporting the
2288 bug.
2290 2008-09-01, Version 4.4.3
2291 * collectd: Fix a memory leak in the threshold checking code.
2292 * memcached plugin: Fix a too short timeout and a related file
2293 descriptor leak.
2294 * memory plugin: A typo in the libstatgrab code has been fixed.
2295 * snmp plugin: Fix a possible memory leak.
2297 2008-07-15, Version 4.4.2
2298 * build system: Use pkg-config to detect the upsclient library.
2299 * collectd: Try even harder to determine the endianness of the
2300 architecture collectd is being built on.
2301 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2302 of disks.
2303 * dns plugin: Fix compilation errors with BIND versions 19991001
2304 through 19991005.
2305 * network plugin: Bugfix in the init routine: The init function
2306 cleared a buffer regardless of its contents. This could lead to lost
2307 values under Solaris.
2308 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2309 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2310 function.
2311 * wireless plugin: Work around incorrect noise and power values
2312 returned by some broken drivers.
2314 2008-06-03, Version 4.4.1
2315 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2316 to kyrone for reporting this.
2317 * collectd: Fixed min/max output in notifications generated by
2318 threshold checking.
2319 * collectd-nagios: Fix the protocol used to communicate with the
2320 daemon.
2321 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2322 initialization has errors. An issue with Perl 5.10 has been fixed.
2323 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2324 René Rebe and Siegmund Gorr for reporting this.
2326 2008-05-06, Version 4.4.0
2327 * collectd: Internal code cleanups.
2328 * collectd: Added support for a `Flush' command in the unixsock and
2329 exec plugins. This command can be used to force a plugin (or all) to
2330 flush its values to disk.
2331 * collectd: Thresholds can now be configured to apply to one data
2332 source only, making it possible to configure different thresholds
2333 for each data source.
2334 * apache, nginx plugins: Added the possibility to disable host and/or
2335 peer verification.
2336 * ascent plugin: The new ascent plugin reads and parses the statistics
2337 page of an Ascent server.
2338 * cpu plugin: Support for the statgrab library has been added.
2339 * disk plugin: The possibility to ignore certain disks or collect only
2340 specific disks has been added.
2341 * disk plugin: Support for the statgrab library has been added.
2342 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
2343 sensor values via IPMI, the intelligent platform management
2344 interface.
2345 * iptables plugin: The iptc library that is used by the iptables
2346 plugin has been added to the distribution, because it is not
2347 provided by all distributions and removed from at least one.
2348 * powerdns plugin: The new powerdns plugin reads statistics from an
2349 authoritative or a recursing PowerDNS name server.
2350 * rrdtool plugin: The size of the files generated with the default
2351 configuration has been decreased.
2352 * tail plugin: The new tail plugin can be used to gather statistics by
2353 continuously reading from log files.
2354 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2355 TeamSpeak2 server and collects statistics about the number of users
2356 and number of channels.
2357 * users plugin: Support for the statgrab library has been added.
2358 * vmem plugin: The new vmem plugin collects very detailed statistics
2359 about the virtual memory subsystem of Linux.
2361 2008-08-30, Version 4.3.4
2362 * Build system: Improved detection of and linking with the statgrab
2363 library.
2364 * collectd: Portability fixes, especially to determine endianness more
2365 reliable.
2366 * Various plugins: Fix format strings.
2367 * disk plugin: A fix for giving disks under Linux 2.4 the right names
2368 again has been applied.
2369 * memcached plugin: Fix a too short timeout and a related file
2370 descriptor leak.
2371 * memory plugin: A typo in the libstatgrab code has been fixed.
2372 * network plugin: A fix in the initialization function solves problems
2373 under Solaris.

2377 added.
2379 2008-04-22, Version 4.3.3
2380 * build system: Improved detection of several libraries, especially if
2381 they are in non-standard paths.
2382 * build system: Portability fixes: Automatically define "_REENTRANT"
2383 if the libc expects it.
2384 * collectd: Error and warning messages have been improved.
2385 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2386 using them.
2387 * apache plugin: Allocate new memory when reading a webpage instead of
2388 using a buffer of static size.
2389 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2390 the program.
2391 * hddtemp plugin: Error and warning messages have been improved.
2392 * sensors plugin: Fix sensor collection for some chip types.
2394 2008-03-29, Version 4.3.2
2395 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2396 `Persist' threshold options.
2397 * collectd: Fix handling of missing values in the global value cache.
2398 * collectd: Improved error messages when parsing the configuration.
2399 * sensors plugin: Fix temperature collection with libsensors4.
2400 * unixsock plugin: Fix mixed input and output operation on streams.
2401 * wireless plugin: Fix reading noise value.
2403 2008-03-05, Version 4.3.1
2404 * exec plugin: Set supplementary group IDs.
2405 * network plugin:
2406 + Use `memcpy' when constructing/parsing a package to avoid
2407 alignment problems on weird architectures, such as Sparc.
2408 + Translate doubles to/from the x86 byte representation to ensure
2409 cross-platform compatibility.
2410 * ping plugin: Correct the handling of the `TTL' setting.
2411 * swap plugin: Reapply a patch for Solaris.
2412 * tcpconns plugin: Portability improvements.
2414 2008-02-18, Version 4.3.0
2415 * collectd: Notifications have been added to the daemon. Notifications
2416 are status messages that may be associated with a data instance.
2417 * collectd: Threshold checking has been added to the daemon. This
2418 means that you can configure threshold values for each data
2419 instance. If this threshold is exceeded a notification will be
2420 created.
2421 * collectd: The new `FQDNLookup' option tells the daemon to use the
2422 full qualified domain name as the hostname, not just the host part
2423 es returned by `gethostname(2)'.
2424 * collectd: Support for more than one `TypesDB' file has been added.
2425 This is useful when one such file is included in a package but one
2426 wants to add custom type definitions.
2427 * collectd: The `Include' config option has been expanded to handle
2428 entire directories and shell wildcards.
2429 * collectdmon: The new `collectdmon' binary detects when collectd
2430 terminates and automatically restarts it again.
2431 * csv plugin: The CSV plugin is now able to store counter values as a
2432 rate, using the `StoreRates' configuration option.
2433 * exec plugin: Handling of notifications has been added and the
2434 ability to pass arguments to the executed programs has been added.
2435 * hddtemp plugin: The new `TranslateDevicename' option lets you
2436 disable the translation from device names to major-minor-numbers.
2437 * logfile plugin: Handling of notifications has been added.
2438 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2439 domain name lookups in this plugin.
2440 * perl plugin: Many internal changes added support for handling multiple
2441 threads making the plugin reasonably usable inside collectd. The API has
2442 been extended to support notifications and export global variables to
2443 Perl plugins; callbacks now have to be identified by name rather than a
2444 pointer to a subroutine. The plugin is no longer experimental.
2445 * uuid plugin: The new UUID plugin sets the hostname to an unique
2446 identifier for this host. This is meant for setups where each client
2447 may migrate to another physical host, possibly going through one or
2448 more name changes in the process. Thanks to Richard Jones from
2449 Red Hat's Emerging Technology group for this plugin.
2450 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2451 CPU, disk and network statistics about guest systems on the same
2452 physical server. Thanks to Richard Jones from Red Hat's Emerging
2453 Technology group for this plugin.
2455 2008-04-22, Version 4.2.7
2456 * build system: Improved detection of several libraries, especially if
2457 they are in non-standard paths.
2458 * build system: Portability fixes: Automatically define "_REENTRANT"
2459 if the libc expects it.
2460 * collectd: Error and warning messages have been improved.
2461 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2462 using them.
2463 * apache plugin: Allocate new memory when reading a webpage instead of
2464 using a buffer of static size.
2465 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2466 the program.
2467 * hddtemp plugin: Error and warning messages have been improved.
2468 * sensors plugin: Fix sensor collection for some chip types.
2470 2008-03-29, Version 4.2.6
2471 * collectd: Improved error messages when parsing the configuration.
2472 * sensors plugin: Fix temperature collection with libsensors4.
2473 * unixsock plugin: Fix mixed input and output operation on streams.
2474 * wireless plugin: Fix reading noise value.
2476 2008-03-04, Version 4.2.5
2477 * apache plugin: Improved initialization and error messages.
2478 * exec plugin: Set supplementary group IDs.
2479 * network plugin:
2480 + Create separate threads for reading from the socket and parsing
2481 and dispatching incoming packets. Versions prior to this may have
2482 problems in high-load situations, where the socket receive buffers
2483 overflows, resulting in gaps in the data.
2484 + Use `memcpy' when constructing/parsing a package to avoid
2485 alignment problems on weird architectures, such as Sparc.
2486 + Translate doubles to/from the x86 byte representation to ensure
2487 cross-platform compatibility.
2488 * ping plugin: Correct the handling of the `TTL' setting.
2489 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2490 * swap plugin: Reapply a patch for Solaris.
2491 * tcpconns plugin: Portability improvements.
2493 2008-01-21, Version 4.2.4
2494 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2495 the permission on the socket as documented in the manpage. Thanks to
2496 Evgeny Chukreev for fixing this issue.
2497 * collectd: The documentation has been improved.
2499 2007-12-28, Version 4.2.3
2500 * sensors plugin: Updated the plugin to build and work with version 3
2501 of the libsensors library.
2503 2007-12-15, Version 4.2.2
2504 * nginx plugin: Incorrect comparison of strings lead to a segfault
2505 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2506 this.
2507 * logfile plugin: The config option `Timestamp' was handled
2508 incorrectly and basically always active. Thanks to Luke Heberling
2509 for fixing this.
2511 2007-11-08, Version 4.2.1
2512 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2513 enabled on the host.
2514 * snmp plugin: Fix a memory leak.
2516 2007-10-27, Version 4.2.0
2517 * collectd: The new config option `Include' lets you include other
2518 configfiles and thus split up your config into smaller parts. This
2519 may be especially interesting for the snmp plugin to keep the data
2520 definitions separate from the host definitions.
2521 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2522 (number of connections, octets and packets for each service and
2523 destination). Thanks to Sebastian Harl for this plugin.
2524 * memcached plugin: The new `memcached' plugin connects to a memcached
2525 daemon process and collects statistics of this distributed caching
2526 system. Thanks to Antony Dovgal for contributing this plugin.
2527 * nginx plugin: The new `nginx' plugin reads the status page of an
2528 nginx daemon and saves the handled connections and requests.
2529 * perl plugin: Many changes, including the added `EnableDebugger'
2530 config option which lets you debug your Perl plugins more easily.
2531 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2532 be more thread-safe otherwise by locking calls to the library.
2533 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2534 correct the values returned by SNMP-agents. If a <data> block is
2535 defined as `table' the instance is now optional. The sequence number
2536 is used as the type-instance in this case. The new `InstancePrefix'
2537 option allows to add arbitrary prefixes to the type-instance.
2538 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2539 certain TCP connections and what state they're in. This can be used
2540 to see how many connections your FTP server has to handle or how
2541 many outgoing connections your mailserver has open.
2543 2008-01-11, Version 4.1.6
2544 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2545 the permission on the socket as documented in the manpage. Thanks to
2546 Evgeny Chukreev for fixing this issue.
2547 * collectd: The documentation has been improved.
2549 2007-12-27, Version 4.1.5
2550 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
2551 memory situations.
2552 * sensors plugin: Updated the plugin to build and work with version 3
2553 of the libsensors library.
2555 2007-11-08, Version 4.1.4
2556 * Build system: Improve detection of the rrd library, especially if
2557 it's in a non-standard location.
2558 * Build system: A bug when parsing the argument for
2559 `--with-libnetsnmp' has been fixed.
2560 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2561 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2562 a deadlock or delay when shutting down the daemon.
2563 * snmp plugin: Fix a memory leak.
2565 2007-10-24, Version 4.1.3
2566 * collectd: A build issue under Solaris has been resolved by renaming
2567 data types.
2568 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2569 be more thread-safe otherwise by locking calls to the library.
2571 2007-09-28, Version 4.1.2
2572 * apcups plugin: Fix reporting of the `load percent' data.
2573 * wireless plugin: Correct the handling of cards returning signal and
2574 noise quality as percentage.
2575 * perl plugin: Fix a possible buffer overflow in get_module_name().
2576 * build system: Further improve the detection of libraries.
2577 * netlink plugin: Build issues under some older versions of the Linux
2578 includes (i. e. Debian Sarge) have been fixed.
2579 * snmp plugin: Fix a potential segfault when a host times out. Add
2580 support for the `timeticks' type.
2582 2007-09-12, Version 4.1.1
2583 * Build system: The detection of `libnetlink' has been improved.
2584 * collectd: The documentation has been fixed in numerous places.
2585 * exec plugin: Setting the group under which to run a program has been
2586 fixed.
2587 * collectd: The `sstrerror' function was improved to work correctly
2588 with the broken GNU version of `strerror_r'.
2589 * collectd: Write an error message to STDERR when loading of a plugin
2590 fails.
2591 * apcups plugin: Fix the `types' used to submit the values: They still
2592 has an `apcups_' prefix which doesn't work anymore.
2593 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2594 whatever the client thinks is `now'..
2596 2007-09-01, Version 4.1.0
2597 * Build system: The build system has been changed to automatically
2598 disable all plugins, which are missing dependencies. The dependency
2599 checking has been removed from the plugins themselves to remove
2600 redundancy.
2601 * Flexible interval: The interval of collected data is now sent along
2602 with the data itself over the network, so that the interval-settings
2603 of server and clients no longer needs to match.
2604 * netlink plugin: The new `netlink' plugin connects to the Linux
2605 kernel using a netlink socket and uses it to query information about
2606 interfaces, qdiscs and classes.
2607 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2608 to not block data collection.
2609 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2610 network devices, such as switches, routers, thermometers, rack
2611 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2612 plugin.
2613 * unixsock plugin: Added the `LISTVAL' command.
2614 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2615 of music played with xmms.
2617 2007-09-28, Version 4.0.9
2618 * apcups plugin: Fix reporting of the `load percent' data.
2619 * wireless plugin: Correct the handling of cards returning signal and
2620 noise quality as percentage.
2621 * perl plugin: Fix a possible buffer overflow in get_module_name().
2623 2007-09-12, Version 4.0.8
2624 * collectd: The `sstrerror' function was improved to work correctly
2625 with the broken GNU version of `strerror_r'.
2626 * collectd: Write an error message to STDERR when loading of a plugin
2627 fails.
2628 * apcups plugin: Fix the `types' used to submit the values: They still
2629 has an `apcups_' prefix which doesn't work anymore.
2630 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2631 whatever the client thinks is `now'..
2633 2007-08-26, Version 4.0.7
2634 * documentation: Some typos have been fixed and some information has
2635 been improved.
2636 * build system: Many fixes for detecting libraries in unusual places,
2637 such as on RedHat systems. The affected libraries are `libcurl',
2638 `libmysql', and `libupsclient'.
2639 * network plugin: Allow the `Port' option to be specified as a number
2640 (i. e. without quotes).
2641 * nut plugin: A fix allows linking the nut plugin against
2642 libupsclient, version >= 2.2.0.
2643 * processes plugin: Fix a potential segmentation fault.
2645 2007-07-30, Version 4.0.6
2646 * sensors plugin: Fix the ignorelist functionality: Only the `type
2647 instance' was used to match against the list, but the documentation
2648 told otherwise. This release fixes the code, so it complies with the
2649 documentation.
2650 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2651 configuration messages will end up in the logging facility.
2652 * conrtib/fedora: The contributed specfile for Fedora has been
2653 updated.
2655 2007-07-05, Version 4.0.5
2656 * Portability: More fixes for OpenBSD have been included.
2658 2007-06-24, Version 4.0.4
2659 * cpu plugin: Fixed the Solaris code.
2660 * dns plugin: Fixed a build issue for OpenBSD.
2661 * interface plugin: Fixed the Solaris code.
2662 * load plugin: Fixed the alternative `/proc' Linux code.
2663 * memory plugin: Fixed the Solaris code.
2664 * oconfig: Don't require `-lfl' anymore.
2666 2007-06-19, Version 4.0.3
2667 * cpu plugin: Fix the Darwin / Mac OS X code.
2668 * ping plugin: Use the return value of `getpid', not its address.
2669 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2670 initialized correctly.
2671 * configure: Added `--with-nan-emulation' to aid cross compilation.
2673 2007-06-12, Version 4.0.2
2674 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2675 they're given in numerically form.
2677 2007-06-07, Version 4.0.1
2678 * iptables plugin: A bug in the configuration routine has been fixed.
2679 Setting a comment in the configfile will no longer cause a
2680 segmentation fault.
2682 2007-06-03, Version 4.0.0
2683 * collectd: The plugin-infrastructure has been changed to allow for
2684 more types of plugins, namely `write' and `log' plugins.
2685 * collectd: The read-function has been changed to read many plugins in
2686 parallel, using threads. Thus, plugins generally need to use
2687 thread-safe functions from now on.
2688 * collectd: The '-t' command line options allows to perform syntax tests
2689 of the configuration file and exit immediately.
2690 * csv plugin: The new `csv' plugin handles output to `comma separated
2691 values'-files.
2692 * rrdtool plugin: The new `rrdtool' plugin handles output to
2693 RRD-files. Data can be cached to combine multiple updates into one
2694 write to increase IO-performance.
2695 * network plugin: The new `network' plugin handles IO via the network.
2696 It implements a different, much more extensible protocol which can
2697 combine many values in one packet, decreasing the number of UDP-
2698 packets being sent. It can read from and send to the network and
2699 with the appropriate configuration even forward packets to other
2700 networks.
2701 * unixsock plugin: The new `unixsock' plugin provides an interface to
2702 communicate with the daemon while it is running. Right now the
2703 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2704 come.
2705 * perl plugin: The new `perl' plugin allows you to write extensions
2706 for collectd in the scripting-language Perl.
2707 * logfile plugin: The new `logfile' plugin writes logmessages to files
2708 or STDOUT or STDERR.
2709 * syslog plugin: The new `syslog' plugin sends logmessages to the
2710 system's syslog daemon.
2711 * entropy plugin: The new `entropy' plugin collects the amount of
2712 entropy currently being available to the system.
2713 * exec plugin: The new `exec' plugin forks child processes and reads
2714 back values provided by the forked processes.
2715 * iptables plugin: The new `iptables' plugin reads counters from
2716 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2717 plugin.
2718 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2719 to Peter Holik for contributing this plugin.
2720 * nut plugin: The new `nut' plugin connects the upsd of the `network
2721 ups tools' and reads information about the connected UPS.
2722 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2723 connections) field was added by Florent Monbillard.
2724 * collectd-nagios: The new `collectd-nagios' binary queries values
2725 from collectd, parses them and exits according to Nagios-standards.
2726 * manpages: The manpages have been improved a lot.
2728 2007-09-28, Version 3.11.7
2729 * wireless plugin: Correct the handling of cards returning signal and
2730 noise quality as percentage.
2732 2007-08-31, Version 3.11.6
2733 * processes plugin: Fix a potential segmentation fault.
2735 2007-05-29, Version 3.11.5
2736 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2737 * ntpd plugin: Fix a potential buffer overflow.
2738 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2739 were accounted as `zombies'.
2741 2007-04-10, Version 3.11.4
2742 * dns plugin: Change the order of includes to make the plugin compile
2743 under FreeBSD.
2745 2007-03-30, Version 3.11.3
2746 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2747 of the unused `COLLECT_KSTAT'.
2749 2007-02-11, Version 3.11.2
2750 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2751 NULL-pointer may have been passed to `printf' which causes a
2752 segfault with some libcs.
2754 2007-02-10, Version 3.11.1
2755 * df plugin: Some wrong defines have been fixed so the plugin works
2756 under Solaris again.
2757 * dns plugin: The usage of a struct has been fixed to work with
2758 non-GNU libcs.
2759 * processes plugin: Some missing defines have been added so the plugin
2760 compiles cleanly under FreeBSD and presumably other UNIXes.
2762 2006-12-22, Version 3.11.0
2763 * collectd: The new command line option `-P' makes it easier for
2764 distributors to change the location of PID-files.
2765 * collectd: The daemon shuts down faster now which makes it easier to
2766 write init.d-scripts for it.
2767 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2768 caused problems every now and then.
2769 * df plugin: New config options allow to ignore certain mountpoints,
2770 filesystem types or devices.
2771 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2772 and interprets it. It collects traffic as well as qtype, opcode and
2773 rcode counts.
2774 * email plugin: Sebastian Harl has contributed this plugin which
2775 counts received mails in categories (e. g. ham, spam, virus), spam
2776 score (as given by SpamAssassin) and check types.
2777 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2778 uses `mbmon' to gather information from sensors on the motherboard.
2779 * processes plugin: Collect detailed statistics for configured
2780 processes, that's process and thread count, CPU usage, resident
2781 segment size and pagefaults.
2782 * multimeter plugin: Peter Holik contributed a new plugin which
2783 queries multimeters.
2784 * sensors plugin: Lubos Stanek has put much effort into improving this
2785 plugin, including `extended naming', collection of voltage values
2786 and the possibility to ignore certain values.
2788 2006-12-21, Version 3.10.4
2789 * Max Kellermann has identified a bug in the server routine: When
2790 opening a socket fails the daemon will (re)try opening the socket in
2791 an endless loop, ultimately leading to a `EMFILE' error.
2793 2006-11-04, Version 3.10.3
2794 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2795 ntpd's reply was sent in more than one packet, the buffer size was
2796 calculated incorrectly, resulting in the reading of uninitialized or
2797 freed memory.
2799 2006-11-01, Version 3.10.2
2800 * The sample config file has been improved.
2801 * Errors in the manpages have been corrected.
2802 * The ping-plugin now adds hosts during initialization, not during
2803 startup. This speeds up startup when no network connectivity is
2804 available. Also, the hosts are being added later when the network is
2805 available.
2806 * Improved BSD-support for the df-plugin.
2807 * Fixed syntax errors in the swap-plugin for Mac OS X.
2808 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2809 plugin.
2810 * Don't disable the mysql-plugin if connecting to the database fails
2811 during initialization. Instead, try again in increasing intervals.
2813 2006-07-19, Version 3.10.1
2814 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2815 the apcups cannot be reached, unconnected sockets will pile up and
2816 eventually lead to `Too many open files' errors.
2818 2006-07-09, Version 3.10.0
2819 * The `disk' plugin has been ported to Darwin.
2820 * The `battery' plugin should work on many Apple computers now.
2821 * The `traffic' plugin can now ignore certain interfaces. Also,
2822 statistics for sent/received packets and errors have been added.
2823 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2824 to Anthony Gialluca for contributing this plugin and providing me
2825 with a test environment :)
2826 * A plugin for monitoring an NTP instance and the local clock drift
2827 has been added.
2829 2006-06-25, Version 3.9.4
2830 * The Solaris code in the `swap' plugin has been changed to reflect
2831 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2832 working this out.
2833 * The debugging system has been fixed to work with the Sun libc.
2834 * When built without librrd the variable `operating_mode' could be
2835 uninitialized. Thanks to David Elliot for reporting the bug.
2837 2006-06-01, Version 3.9.3
2838 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2839 operating systems also profit from the changes, but I wasn't able to
2840 check that.
2841 * Changed the build system to find the netinet-includes under FreeBSD
2842 and therefore successfully build the `liboping' library there.
2844 2006-05-09, Version 3.9.2
2845 * Applied a patch to the `liboping' library. Due to a bug in the
2846 sequence checking the `ping' plugin stopped working after
2847 approximately 7.6 days.
2849 2006-05-09, Version 3.8.5
2850 * Applied a patch to the `liboping' library. Due to a bug in the
2851 sequence checking the `ping' plugin stopped working after
2852 approximately 7.6 days.
2854 2006-04-21, Version 3.9.1
2855 * Build issues with Solaris and possible other architectures have been
2856 resolved.
2857 * Problems when building the `apache'-plugin without `libcurl' have
2858 been resolved.
2859 * A bug in the `ping' plugin has been fixed. Sorry folks.
2861 2006-04-02, Version 3.9.0
2862 * A plugin to monitor the Apache webserver has been added.
2863 <http://httpd.apache.org/>
2864 * A plugin to collect statistics about virtual servers using VServer.
2865 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2866 this plugin :)
2867 * A plugin for wireless LAN cards has been added. It monitors signal
2868 strength, link quality and noise ratio..
2869 * A plugin for Apple hardware sensors has been added.
2870 * An option to compile collectd with different `step' and `heartbeat'
2871 settings has been added. The size of RRAs is no longer static but
2872 calculated based on the settings for `step' and `width'.
2873 * The `ping' plugin can now be configured to use a certain TTL.
2874 * A plugin to monitor the hardware sensors of Apple computers has been
2875 added.
2876 * The plugins `cpu', `memory', `processes' and `traffic' have been
2877 ported to Mach/Darwin (Mac OS X).
2878 * The `log mode' has been contributed by Christophe Kalt. It writes
2879 the data into text files rather than RRD files.
2881 2006-04-09, Version 3.8.4
2882 * Applied patch by Vincent Stehlé which improves the disk-name
2883 resolution in the `hddtemp' plugin for Linux systems.
2885 2006-04-02, Version 3.8.3
2886 * Applied a patch by James Byers: The MySQL plugin was not working
2887 with MySQL 5.0.2 or later.
2889 2006-03-14, Version 3.8.2
2890 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2891 the GNU libc, because it points to `/etc/fstab' rather than
2892 `/etc/mtab'.
2894 2006-03-13, Version 3.8.1
2895 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2896 * Fixes in the debian `postinst' and `init.d' scripts.
2898 2006-03-09, Version 3.8.0
2899 * The `ping' plugin no longer uses `libping' but a self written
2900 library named `liboping'. With this library it's possible to ping
2901 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2903 2006-02-18, Version 3.7.2
2904 * A simple bug in the `battery' plugin has been fixed. It should now
2905 work with ACPI based batteries as well. Thanks to Sebastian for
2906 fixing this.
2907 * Fixing a bug that prevented collectd to be built without librrd.
2908 Thanks to Werner Heuser for reporting it.
2910 2006-02-04, Version 3.7.1
2911 * The new network code has been improved to build with older versions
2912 of glibc.
2913 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2914 to Tommie Gannert for this patch.
2916 2006-01-30, Version 3.7.0
2917 * The `battery' plugin has been added. It collects information about
2918 laptop batteries..
2919 * The MySQL plugin has been improved: It now writes two more RRD
2920 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2921 * The `cpufreq' plugin now reads another file since the file it did
2922 read so far causes much overhead in the kernel. Also, you need root
2923 to read the old file, but not to read the new one.
2924 * The `hddtemp' plugin can now be configured to connect to another
2925 address and/or port than localhost.
2926 * The `df' plugin now prefers `statvfs' over `statfs'.
2927 * The network code has been rewritten. collectd now supports unicast
2928 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2929 be set in the configfile.
2931 2006-01-24, Version 3.6.2
2932 * Due to a bug in the configfile handling collectd wouldn't start in
2933 client mode. This released fixes this.
2935 2006-01-20, Version 3.6.1
2936 * Due to a bug in `configure.in' all modules and the binary were
2937 linked against `libmysqlclient'. This issue is solved by this
2938 release.
2940 2006-01-17, Version 3.6.0
2941 * A config file has been added. This allows for loading only specific
2942 plugins.
2943 * A `df' plugin has been added.
2944 * A `mysql' plugin has been added.
2945 * The `ping' plugin doesn't entirely give up hope when a socket error
2946 occurred, but will back of and increase the intervals between tries.
2948 2006-01-21, Version 3.5.2
2949 * Fixed yet another bug in the signal handling.. Stupid typo..
2950 * Improved the ping plugin to not give up on socket errors (backport
2951 from 3.6.0).
2953 2005-12-18, Version 3.5.1
2954 * The PID-file is now deleted correctly when shutting down the daemon.
2955 * SIGINT and SIGTERM are now handled correctly.
2957 2005-12-16, Version 3.5.0 (Revision 326)
2958 * A bug in the `load' module under Solaris has been fixed.
2959 * The `users' module has been contributed by Sebastian Harl. It counts
2960 currently logged in users.
2961 * The CPU module now works under FreeBSD without the use of
2962 `libstatgrab', however SMP support is missing.
2963 * The default directories for the RRD files and the PID file now
2964 depend on the compile time setting of `localstatedir'.
2966 2005-11-15, Version 3.4.0 (Revision 236)
2967 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2968 from gentoo's bugzilla for writing the patch.
2969 * The build dependency for librrd has been removed. Binaries built
2970 without librrd are client-only and will multicast their value as
2971 with the `-c' argument.
2972 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2973 * The newly introduced `-f' switch prevents daemon initialization
2974 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2975 Barcellos for this patch.
2977 2005-11-04, Version 3.3.0 (Revision 216)
2978 * New modules have been added:
2979 - `serial', for monitoring traffic on the serial interfaces
2980 - `nfs', for graphing NFS procedure calls
2981 - `tape', traffic from/to tape devices
2982 * The memory.rrd now accepts more than 4Gig of memory.
2984 2005-10-26, Version 3.2.0 (Revision 200)
2985 * Support for graphing the processes has been added (thanks to Lyonel
2986 Vincent)
2987 * If reading from hddtemp fails collectd will increase the time
2988 between polls up to one day.
2989 * The init.d files have been improved.
2990 * Problems with the spec file have been fixed.
2992 2005-10-16, Version 3.1.0 (Revision 194)
2993 * Added the `setsid' syscall to the startup code.
2994 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2996 2005-09-30, Version 3.0.0 (Revision 184)
2997 * The ability to send/receive data to/from the network (think
2998 multicast) has been added.
2999 * Modules have been split up into shared libraries can be loaded at
3000 runtime. The biggest advantage is that the core program doesn't need
3001 to be linked against an external library.
3002 * A patch by George Kargiotakis has been applied: It fixes the sensors
3003 behaviour then more than one sensor is being queried.
3005 2005-09-16, Version 2.1.0 (Revision 172)
3006 * A module for swap statistics has been added.
3008 2005-09-09, Version 2.0.0 (Revision 135)
3009 * Filenames can no longer be configured at program startup. The only
3010 options as of this version are the directory and ping hosts.
3011 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3012 Soft-IRQ statistics are added to `System'.
3013 * Diskstats now collect read and write bytes, not sectors.
3014 * Ping statistics can now be collected for more than one host. There
3015 is no default any more: If no host is given no host will be pinged.
3016 * A self-written patch for libping has been applied so it builds
3017 cleanly.
3019 2005-09-01, Version 1.8.1 (Revision 123)
3020 * Much improved configure-script: libraries and features may now be
3021 disabled.
3022 * More detailed warnings/error messages when RRD update fails.
3024 2005-08-29, Version 1.8.0:
3025 * Support for collecting disk statistics under Solaris.
3027 2005-08-25, Version 1.7.0:
3028 * Support for libstatgrab[1] for load, memory usage and network
3029 traffic. CPU- and disk-usage are not (yet) supported, since
3030 libstatgrab returns insufficient information. I will contact the
3031 authors.
3032 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3033 aren't necessarily counted linear which is now handled correctly.
3034 [1]: http://www.i-scream.org/libstatgrab/
3036 2005-08-21, Version 1.6.0:
3037 * Basic support for Solaris: System load and cpu-usage can be
3038 collected under Solaris, too. Other stats will follow later.
3039 * Many fixes in the autoconf-script
3040 * Collection/Museum scripts have been added under contrib/museum
3041 * collectd may now be started in unprivileged mode, though ping
3042 statistics will not work.
3044 2005-07-17, Version 1.5.1:
3045 * Diskstats-RRDs now use major/minor for naming. Some systems have
3046 weird strings as disk-names..
3048 2005-07-17, Version 1.5:
3049 * A new module, diskstats, has been added. It collects information
3050 about the disks and partitions.
3052 2005-07-11, Version 1.4.2:
3053 * The meminfo module has been changed to work with more platforms
3054 and/or kernel versions.
3056 2005-07-10, Version 1.4.1: Correct traffic stats
3057 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3058 forgot to correct when I changed that module.
3060 2005-07-09, Version 1.4: More traffic stats
3061 * Traffic is now collected for all interfaces that can be found
3062 * Temperature-statistics are read from lm-sensors if available
3064 2005-07-08, Version 1.3: CPU stats
3065 * Collecting CPU statistics now
3067 2005-07-12, Version 1.2: Using syslog
3068 * collectd is now using the syslog facility to report errors, warnings
3069 and the like..
3070 * The default directory is now /var/db/collectd
3072 2005-07-10, Version 1.1: Minor changes
3073 * Nothing really useful to say ;)
3075 2005-07-09, Version 1.0: Initial Version
3076 * The following modules are provided:
3077 * Load average
3078 * Ping time
3079 * Traffic
3080 * Memory info
