1846 primarily BSDs, don't take it well and crash.
1847 * oracle plugin: Portability to 64 bit systems has been improved.
1848 * postgresql plugin: The default configuration has been improved.
1849 * rrdtool plugin: Fix a possible race condition: If the network plugin
1850 is brought and dispatches a value before the rrdtool plugin is
1851 initialized, the daemon may crash.
1853 2009-02-22, Version 4.6.1
1854 * collectd: Many documentation fixes.
1855 * Collectd::Unixsock: Error handling has been improved.
1856 * regex match: Don't link with the PCRE library.
1857 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1858 for finding and fixing most of them.
1859 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1860 faults. Thanks to Peter Holik for his patch.
1862 2009-02-16, Version 4.6.0
1863 * collectd: Added the `filter chain' infrastructure, which allows the
1864 user to use `matches' and `targets' to control value processing.
1865 * collectd: The new `-T' command line argument allows more in-depth
1866 testing of a configuration. Thanks to Doug MacEachern for the patch.
1867 * collectd-nagios: The Nagios integration command has been updated to
1868 use libcollectdclient. The `percentage' aggregation function has
1869 been added. Thanks to Fabian Linzberger for the patch.
1870 * libcollectdclient: A library which abstracts communication with the
1871 unixsock plugin for clients has been added.
1872 * regex match: Match values by their identifies using regular
1874 * timediff match: Match for values with an invalid timestamp.
1875 * value match: Select values by their data sources' values.
1876 * notification target: Create and dispatch a notification.
1877 * replace target: Replace parts of an identifier using regular
1879 * set target: Set (overwrite) entire parts of an identifier.
1880 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1881 statistics, allowing very detailed name server statistics. Thanks to
1882 Bruno Prémont for this plugin.
1883 * cpu plugin: Report `interrupt' separately when using
1884 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1885 example for native OpenBSD support, has been added. Thanks to Simon
1886 Kuhnle for the patch.
1887 * csv plugin: Make it possible to write values to STDOUT instead of
1888 files. This is meant for testing purposes mostly. The output written
1889 to STDOUT is compatible with the exec plugin. Thanks to Doug
1890 MacEachern for the patch.
1891 * curl plugin: This new plugin can be used to read web pages and parse
1892 them using the same mechanism that's used in the tail plugin.
1893 * dbi plugin: This new plugin allows you to connect to a variety of
1894 relational databases and use SQL to gather custom statistics from
1895 it. It is similar to the already existing PostgreSQL plugin but uses
1896 libdbi to communicate with the database(s).
1897 * interface plugin: Use the ignorelist framework when selecting /
1898 ignoring interfaces. This allows one to use regular expressions to
1899 select interfaces, too.
1900 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1901 Thanks to Bruno Prémont for this patch.
1902 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1904 * mysql plugin: Allow connecting to a database via the UNIX domain
1905 socket, too. Thanks to Mirko Buffoni for the patch.
1906 * network plugin: Further performance improvements for the receive
1907 code. This hopefully will help very large setups.
1908 * openvpn plugin: This new plugin collects statistics provided by the
1909 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1910 * oracle plugin: This new plugin allows you to connect to an Oracle
1911 database and use SQL to gather custom statistics from it. It is
1912 similar to the already existing PostgreSQL plugin.
1913 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1915 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1916 * perl plugin: Added support for `notification meta data'.
1917 * perl plugin: Added support for the `filter chain' infrastructure by
1918 allowing plugins to register `matches' and `targets'.
1919 * postgresql plugin: The preferred configuration syntax has been
1920 updated to be in line with the syntax used by the new dbi and oracle
1921 plugins. The compatibility code for the old syntax is present.
1922 Support for the new `Result' blocks and the interval parameter has
1924 * processes plugin: Stacksize and virtual memory usage statistics have
1925 been added. Portability fixes.
1926 * rrdcached plugin: This new plugin uses the (still in development)
1927 RRD accelerator daemon, rrdcached. This daemon works very similar to
1928 the original rrdtool plugin of collectd, but adds some more nice
1930 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1933 2009-05-09, Version 4.5.4
1934 * Build system, various plugins: Many build fixes for FreeBSD,
1935 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1936 for many fixes and providing a build system for many platforms,
1937 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1938 providing an OpenBSD system.
1939 * collectd: Fix a potential race condition when creating directories.
1940 * battery plugin: Don't complain about a missing directory every
1942 * dns plugin: Slight portability fixes.

1944 Thorsten von Eicken for reporting this problem.
1945 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1946 Tomasz Pala for the patch.
1947 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1949 * rrdtool plugin: Fix a possible race condition: If the network plugin
1950 is initialized and dispatches a value before the rrdtool plugin is
1951 initialized, the daemon may crash.
1952 * memory plugin: Fix a potential problem under Solaris.
1954 2009-02-22, Version 4.5.3

1962 faults. Thanks to Peter Holik for his patch.
1963 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1964 code. Thanks to "thated" for reporting this.
1966 2009-01-02, Version 4.5.2
1967 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1968 file may be in both locations, especially when the database was
1969 installed in a non-standard path. Thanks to Dusty Doris for
1971 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1972 Solaris, in the configure script automatically.
1973 * build system, tcpconns plugin: Check for `kvm_nlist' and
1974 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1975 library with similar functions to the BSD variant, but doesn't
1976 provide these necessary functions.
1977 * collectd.conf(5): Various fixes and clarifications.
1978 * collectd: Remove a GNUism (unnamed unions), thus improving
1980 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1981 This solves portability problems, especially for Solaris.
1982 * dns plugin: Fix a portability problem with NetBSD.
1983 * filecount plugin: Fix an off-by-one error. This error may cause a
1985 * network plugin: Fix the handling of `type' in the network protocol.
1986 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1987 much larger buffer. This caused the `type' to be transferred much
1988 more often than necessary. In some cases, e. g. the `cpu' and
1989 `cpufreq' plugins being used at the same time, data may be corrupted
1990 in those files. Thanks to Bruno Prémont for debugging and reporting
1992 * processes plugin: Fix a possible segmentation fault when specifying
1993 invalid configuration options.
1994 * unixsock plugin: Make sure the initialization function is run only
1995 once. This resolves a file descriptor leak under systems which run
1996 the initialization more than once, such as Solaris.
1998 2008-10-16, Version 4.5.1
1999 * build system: Change `--enable-<plugin>' to abort with an error if
2000 dependencies are not met. Thanks to Bruno Prémont for the patch.
2001 Also, the poisoning of various string functions has been restricted
2003 * collectd: Fix a memory leak in the global value cache. With every
2004 *missing* value a couple of bytes would be leaked. Another memory
2005 leak in the configuration handling code has been fixed. Thanks to
2006 Niraj Tolia for reporting these issues.
2007 * collectd: Fix an off-by-one error in the ignorelist functionality.
2008 When using regular expressions, the last character would be missing,
2009 possibly matching differently from what one would expect.
2010 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2012 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2013 Linzberger for reporting the bug.
2014 * iptables plugin: Fix an off-by-one error. If a string was just one
2015 character too long, it was truncated instead of reporting an error.
2016 * network plugin: Fix a memory leak in the configuration handling
2017 code. Thanks to Niraj Tolia for reporting this issue.
2018 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2019 * postgresql plugin: Don't reopen connection during reinitialization.
2020 This fixes a bug under Solaris and potentially other platforms.
2021 Missing calls to `PQclear' have been added, too. This fixes memory
2022 leaks. Thanks to ``Admin'' for reporting these bugs.
2023 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2025 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2026 problems with some `libc's. Thanks to Matthias Lay for reporting the
2029 2008-09-04, Version 4.5.0
2030 * collectd: Added the ability to flush certain identifiers.
2031 * collectd: The concept of `notification meta data' has been
2033 * filecount plugin: The new filecount plugin counts the number of
2034 files in a directory and its subdirectories.
2035 * ipmi plugin: Sensor names have been changed to ensure unique names.
2036 Notifications upon added and removed sensors can now be generated.
2037 * notify_desktop plugin: This new plugin sends notifications to the
2038 X desktop using the structure defined in the `Desktop Notification
2040 * notify_email plugin: This new plugin sends out notifications via
2041 email, using the `esmtp' library.
2042 * onewire plugin: The new experimental(!) onewire plugin reads values,
2043 such as temperatures, from sensors connected to the computer via the
2045 * perl plugin: Improved synchronized access to internal data structures
2046 and fixed a possible dead-lock.
2047 * perl plugin: Added the ability to flush certain identifiers and marked
2048 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2050 * perl plugin: Added the ability to configure Perl plugins.
2051 * postgresql plugin: The new postgresql plugin collects statistics
2052 about or from a PostgreSQL database.
2053 * processes plugin: The `ProcessMatch' option has been added.
2054 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2056 * tcpconns plugin: This plugin has been ported to OpenBSD.
2057 * thermal plugin: The new thermal plugin collects system temperatures
2058 using Linux ACPI thermal zone data.
2060 2009-01-02, Version 4.4.5
2061 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2062 file may be in both locations, especially when the database was
2063 installed in a non-standard path. Thanks to Dusty Doris for
2065 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2066 Solaris, in the configure script automatically.
2067 * collectd.conf(5): Various fixes and clarifications.
2068 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2069 portability problems, especially for Solaris.
2070 * dns plugin: Fix a portability problem with NetBSD.
2071 * network plugin: Fix the handling of `type' in the network protocol.
2072 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2073 much larger buffer. This caused the `type' to be transferred much
2074 more often than necessary. In some cases, e. g. the `cpu' and
2075 `cpufreq' plugins being used at the same time, data may be corrupted
2076 in those files. Thanks to Bruno Prémont for debugging and reporting
2078 * unixsock plugin: Make sure the initialization function is run only
2079 once. This resolves a file descriptor leak under systems which run
2080 the initialization more than once, such as Solaris.
2082 2008-10-16, Version 4.4.4
2083 * build system: Change `--enable-<plugin>' to abort with an error if
2084 dependencies are not met. Thanks to Bruno Prémont for the patch.
2085 Also, the poisoning of various string functions has been restricted
2087 * collectd: Fix a memory leak in the global value cache. With every
2088 *missing* value a couple of bytes would be leaked. Another memory
2089 leak in the configuration handling code has been fixed. Thanks to
2090 Niraj Tolia for reporting these issues.
2091 * collectd: Fix an off-by-one error in the ignorelist functionality.
2092 When using regular expressions, the last character would be missing,
2093 possibly matching differently from what one would expect.
2094 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2096 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2097 Linzberger for reporting the bug.

2099 code. Thanks to Niraj Tolia for reporting this issue.
2100 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2101 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2102 problems with some `libc's. Thanks to Matthias Lay for reporting the
2105 2008-09-01, Version 4.4.3
2106 * collectd: Fix a memory leak in the threshold checking code.
2107 * memcached plugin: Fix a too short timeout and a related file
2109 * memory plugin: A typo in the libstatgrab code has been fixed.
2110 * snmp plugin: Fix a possible memory leak.
2112 2008-07-15, Version 4.4.2
2113 * build system: Use pkg-config to detect the upsclient library.
2114 * collectd: Try even harder to determine the endianness of the
2115 architecture collectd is being built on.
2116 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2118 * dns plugin: Fix compilation errors with BIND versions 19991001
2120 * network plugin: Bugfix in the init routine: The init function
2121 cleared a buffer regardless of its contents. This could lead to lost
2122 values under Solaris.
2123 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2124 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2126 * wireless plugin: Work around incorrect noise and power values
2127 returned by some broken drivers.
2129 2008-06-03, Version 4.4.1
2130 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2131 to kyrone for reporting this.
2132 * collectd: Fixed min/max output in notifications generated by
2134 * collectd-nagios: Fix the protocol used to communicate with the
2136 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2137 initialization has errors. An issue with Perl 5.10 has been fixed.
2138 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2139 René Rebe and Siegmund Gorr for reporting this.
2141 2008-05-06, Version 4.4.0
2142 * collectd: Internal code cleanups.
2143 * collectd: Added support for a `Flush' command in the unixsock and
2144 exec plugins. This command can be used to force a plugin (or all) to
2145 flush its values to disk.
2146 * collectd: Thresholds can now be configured to apply to one data
2147 source only, making it possible to configure different thresholds
2148 for each data source.
2149 * apache, nginx plugins: Added the possibility to disable host and/or
2151 * ascent plugin: The new ascent plugin reads and parses the statistics
2152 page of an Ascent server.
2153 * cpu plugin: Support for the statgrab library has been added.

2164 authoritative or a recursing PowerDNS name server.
2165 * rrdtool plugin: The size of the files generated with the default
2166 configuration has been decreased.
2167 * tail plugin: The new tail plugin can be used to gather statistics by
2168 continuously reading from log files.
2169 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2170 TeamSpeak2 server and collects statistics about the number of users
2171 and number of channels.
2172 * users plugin: Support for the statgrab library has been added.
2173 * vmem plugin: The new vmem plugin collects very detailed statistics
2174 about the virtual memory subsystem of Linux.
2176 2008-08-30, Version 4.3.4
2177 * Build system: Improved detection of and linking with the statgrab

2198 if the libc expects it.
2199 * collectd: Error and warning messages have been improved.
2200 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2202 * apache plugin: Allocate new memory when reading a webpage instead of
2203 using a buffer of static size.
2204 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2206 * hddtemp plugin: Error and warning messages have been improved.
2207 * sensors plugin: Fix sensor collection for some chip types.
2209 2008-03-29, Version 4.3.2

2215 * unixsock plugin: Fix mixed input and output operation on streams.
2216 * wireless plugin: Fix reading noise value.
2218 2008-03-05, Version 4.3.1
2219 * exec plugin: Set supplementary group IDs.
2221 + Use `memcpy' when constructing/parsing a package to avoid
2222 alignment problems on weird architectures, such as Sparc.
2223 + Translate doubles to/from the x86 byte representation to ensure
2224 cross-platform compatibility.
2225 * ping plugin: Correct the handling of the `TTL' setting.
2226 * swap plugin: Reapply a patch for Solaris.
2227 * tcpconns plugin: Portability improvements.
2229 2008-02-18, Version 4.3.0
2230 * collectd: Notifications have been added to the daemon. Notifications
2231 are status messages that may be associated with a data instance.
2232 * collectd: Threshold checking has been added to the daemon. This
2233 means that you can configure threshold values for each data
2234 instance. If this threshold is exceeded a notification will be
2236 * collectd: The new `FQDNLookup' option tells the daemon to use the
2237 full qualified domain name as the hostname, not just the host part
2238 es returned by `gethostname(2)'.
2239 * collectd: Support for more than one `TypesDB' file has been added.
2240 This is useful when one such file is included in a package but one
2241 wants to add custom type definitions.
2242 * collectd: The `Include' config option has been expanded to handle
2243 entire directories and shell wildcards.
2244 * collectdmon: The new `collectdmon' binary detects when collectd
2245 terminates and automatically restarts it again.
2246 * csv plugin: The CSV plugin is now able to store counter values as a
2247 rate, using the `StoreRates' configuration option.
2248 * exec plugin: Handling of notifications has been added and the
2249 ability to pass arguments to the executed programs has been added.
2250 * hddtemp plugin: The new `TranslateDevicename' option lets you
2251 disable the translation from device names to major-minor-numbers.
2252 * logfile plugin: Handling of notifications has been added.
2253 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2254 domain name lookups in this plugin.
2255 * perl plugin: Many internal changes added support for handling multiple
2256 threads making the plugin reasonably usable inside collectd. The API has
2257 been extended to support notifications and export global variables to
2258 Perl plugins; callbacks now have to be identified by name rather than a
2259 pointer to a subroutine. The plugin is no longer experimental.
2260 * uuid plugin: The new UUID plugin sets the hostname to an unique
2261 identifier for this host. This is meant for setups where each client
2262 may migrate to another physical host, possibly going through one or
2263 more name changes in the process. Thanks to Richard Jones from
2264 Red Hat's Emerging Technology group for this plugin.
2265 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2266 CPU, disk and network statistics about guest systems on the same
2267 physical server. Thanks to Richard Jones from Red Hat's Emerging
2268 Technology group for this plugin.
2270 2008-04-22, Version 4.2.7
2271 * build system: Improved detection of several libraries, especially if
2272 they are in non-standard paths.
2273 * build system: Portability fixes: Automatically define "_REENTRANT"
2274 if the libc expects it.
2275 * collectd: Error and warning messages have been improved.
2276 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before

2292 * apache plugin: Improved initialization and error messages.
2293 * exec plugin: Set supplementary group IDs.
2295 + Create separate threads for reading from the socket and parsing
2296 and dispatching incoming packets. Versions prior to this may have
2297 problems in high-load situations, where the socket receive buffers
2298 overflows, resulting in gaps in the data.
2299 + Use `memcpy' when constructing/parsing a package to avoid
2300 alignment problems on weird architectures, such as Sparc.
2301 + Translate doubles to/from the x86 byte representation to ensure
2302 cross-platform compatibility.
2303 * ping plugin: Correct the handling of the `TTL' setting.
2304 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2305 * swap plugin: Reapply a patch for Solaris.

2308 2008-01-21, Version 4.2.4
2309 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2310 the permission on the socket as documented in the manpage. Thanks to
2311 Evgeny Chukreev for fixing this issue.
2312 * collectd: The documentation has been improved.
2314 2007-12-28, Version 4.2.3
2315 * sensors plugin: Updated the plugin to build and work with version 3
2316 of the libsensors library.
2318 2007-12-15, Version 4.2.2
2319 * nginx plugin: Incorrect comparison of strings lead to a segfault
2320 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2322 * logfile plugin: The config option `Timestamp' was handled
2323 incorrectly and basically always active. Thanks to Luke Heberling
2326 2007-11-08, Version 4.2.1
2327 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2328 enabled on the host.
2329 * snmp plugin: Fix a memory leak.
2331 2007-10-27, Version 4.2.0
2332 * collectd: The new config option `Include' lets you include other
2333 configfiles and thus split up your config into smaller parts. This
2334 may be especially interesting for the snmp plugin to keep the data
2335 definitions separate from the host definitions.
2336 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2337 (number of connections, octets and packets for each service and
2338 destination). Thanks to Sebastian Harl for this plugin.
2339 * memcached plugin: The new `memcached' plugin connects to a memcached
2340 daemon process and collects statistics of this distributed caching
2341 system. Thanks to Antony Dovgal for contributing this plugin.
2342 * nginx plugin: The new `nginx' plugin reads the status page of an
2343 nginx daemon and saves the handled connections and requests.
2344 * perl plugin: Many changes, including the added `EnableDebugger'
2345 config option which lets you debug your Perl plugins more easily.
2346 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2347 be more thread-safe otherwise by locking calls to the library.
2348 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2349 correct the values returned by SNMP-agents. If a <data> block is
2350 defined as `table' the instance is now optional. The sequence number
2351 is used as the type-instance in this case. The new `InstancePrefix'
2352 option allows to add arbitrary prefixes to the type-instance.
2353 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2354 certain TCP connections and what state they're in. This can be used
2355 to see how many connections your FTP server has to handle or how
2356 many outgoing connections your mailserver has open.
2358 2008-01-11, Version 4.1.6
2359 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2360 the permission on the socket as documented in the manpage. Thanks to
2361 Evgeny Chukreev for fixing this issue.
2362 * collectd: The documentation has been improved.
2364 2007-12-27, Version 4.1.5
2365 * rrdtool plugin: Fix a memory leak that only occurred in very-low-

2368 of the libsensors library.
2370 2007-11-08, Version 4.1.4
2371 * Build system: Improve detection of the rrd library, especially if
2372 it's in a non-standard location.
2373 * Build system: A bug when parsing the argument for
2374 `--with-libnetsnmp' has been fixed.
2375 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2376 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2377 a deadlock or delay when shutting down the daemon.
2378 * snmp plugin: Fix a memory leak.
2380 2007-10-24, Version 4.1.3
2381 * collectd: A build issue under Solaris has been resolved by renaming
2383 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2384 be more thread-safe otherwise by locking calls to the library.
2386 2007-09-28, Version 4.1.2
2387 * apcups plugin: Fix reporting of the `load percent' data.
2388 * wireless plugin: Correct the handling of cards returning signal and
2389 noise quality as percentage.
2390 * perl plugin: Fix a possible buffer overflow in get_module_name().
2391 * build system: Further improve the detection of libraries.
2392 * netlink plugin: Build issues under some older versions of the Linux
2393 includes (i. e. Debian Sarge) have been fixed.
2394 * snmp plugin: Fix a potential segfault when a host times out. Add
2395 support for the `timeticks' type.
2397 2007-09-12, Version 4.1.1
2398 * Build system: The detection of `libnetlink' has been improved.
2399 * collectd: The documentation has been fixed in numerous places.
2400 * exec plugin: Setting the group under which to run a program has been
2402 * collectd: The `sstrerror' function was improved to work correctly
2403 with the broken GNU version of `strerror_r'.
2404 * collectd: Write an error message to STDERR when loading of a plugin
2406 * apcups plugin: Fix the `types' used to submit the values: They still
2407 has an `apcups_' prefix which doesn't work anymore.
2408 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2409 whatever the client thinks is `now'..
2411 2007-09-01, Version 4.1.0
2412 * Build system: The build system has been changed to automatically
2413 disable all plugins, which are missing dependencies. The dependency
2414 checking has been removed from the plugins themselves to remove
2416 * Flexible interval: The interval of collected data is now sent along
2417 with the data itself over the network, so that the interval-settings
2418 of server and clients no longer needs to match.
2419 * netlink plugin: The new `netlink' plugin connects to the Linux
2420 kernel using a netlink socket and uses it to query information about
2421 interfaces, qdiscs and classes.
2422 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2423 to not block data collection.
2424 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2425 network devices, such as switches, routers, thermometers, rack
2426 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2428 * unixsock plugin: Added the `LISTVAL' command.
2429 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2430 of music played with xmms.
2432 2007-09-28, Version 4.0.9
2433 * apcups plugin: Fix reporting of the `load percent' data.
2434 * wireless plugin: Correct the handling of cards returning signal and
2435 noise quality as percentage.
2436 * perl plugin: Fix a possible buffer overflow in get_module_name().
2438 2007-09-12, Version 4.0.8
2439 * collectd: The `sstrerror' function was improved to work correctly
2440 with the broken GNU version of `strerror_r'.
2441 * collectd: Write an error message to STDERR when loading of a plugin
2443 * apcups plugin: Fix the `types' used to submit the values: They still
2444 has an `apcups_' prefix which doesn't work anymore.
2445 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2446 whatever the client thinks is `now'..
2448 2007-08-26, Version 4.0.7
2449 * documentation: Some typos have been fixed and some information has
2451 * build system: Many fixes for detecting libraries in unusual places,
2452 such as on RedHat systems. The affected libraries are `libcurl',
2453 `libmysql', and `libupsclient'.
2454 * network plugin: Allow the `Port' option to be specified as a number
2455 (i. e. without quotes).
2456 * nut plugin: A fix allows linking the nut plugin against
2457 libupsclient, version >= 2.2.0.
2458 * processes plugin: Fix a potential segmentation fault.
2460 2007-07-30, Version 4.0.6
2461 * sensors plugin: Fix the ignorelist functionality: Only the `type
2462 instance' was used to match against the list, but the documentation
2463 told otherwise. This release fixes the code, so it complies with the
2465 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2466 configuration messages will end up in the logging facility.
2467 * conrtib/fedora: The contributed specfile for Fedora has been
2470 2007-07-05, Version 4.0.5
2471 * Portability: More fixes for OpenBSD have been included.
2473 2007-06-24, Version 4.0.4
2474 * cpu plugin: Fixed the Solaris code.

2476 * interface plugin: Fixed the Solaris code.
2477 * load plugin: Fixed the alternative `/proc' Linux code.
2478 * memory plugin: Fixed the Solaris code.
2479 * oconfig: Don't require `-lfl' anymore.
2481 2007-06-19, Version 4.0.3
2482 * cpu plugin: Fix the Darwin / Mac OS X code.
2483 * ping plugin: Use the return value of `getpid', not its address.
2484 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2485 initialized correctly.
2486 * configure: Added `--with-nan-emulation' to aid cross compilation.
2488 2007-06-12, Version 4.0.2
2489 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2490 they're given in numerically form.
2492 2007-06-07, Version 4.0.1
2493 * iptables plugin: A bug in the configuration routine has been fixed.
2494 Setting a comment in the configfile will no longer cause a
2497 2007-06-03, Version 4.0.0
2498 * collectd: The plugin-infrastructure has been changed to allow for
2499 more types of plugins, namely `write' and `log' plugins.
2500 * collectd: The read-function has been changed to read many plugins in
2501 parallel, using threads. Thus, plugins generally need to use
2502 thread-safe functions from now on.
2503 * collectd: The '-t' command line options allows to perform syntax tests
2504 of the configuration file and exit immediately.
2505 * csv plugin: The new `csv' plugin handles output to `comma separated
2507 * rrdtool plugin: The new `rrdtool' plugin handles output to
2508 RRD-files. Data can be cached to combine multiple updates into one
2509 write to increase IO-performance.
2510 * network plugin: The new `network' plugin handles IO via the network.
2511 It implements a different, much more extensible protocol which can
2512 combine many values in one packet, decreasing the number of UDP-
2513 packets being sent. It can read from and send to the network and
2514 with the appropriate configuration even forward packets to other
2516 * unixsock plugin: The new `unixsock' plugin provides an interface to
2517 communicate with the daemon while it is running. Right now the
2518 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2520 * perl plugin: The new `perl' plugin allows you to write extensions
2521 for collectd in the scripting-language Perl.
2522 * logfile plugin: The new `logfile' plugin writes logmessages to files
2523 or STDOUT or STDERR.
2524 * syslog plugin: The new `syslog' plugin sends logmessages to the
2525 system's syslog daemon.
2526 * entropy plugin: The new `entropy' plugin collects the amount of
2527 entropy currently being available to the system.
2528 * exec plugin: The new `exec' plugin forks child processes and reads
2529 back values provided by the forked processes.
2530 * iptables plugin: The new `iptables' plugin reads counters from
2531 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2533 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2534 to Peter Holik for contributing this plugin.
2535 * nut plugin: The new `nut' plugin connects the upsd of the `network
2536 ups tools' and reads information about the connected UPS.
2537 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2538 connections) field was added by Florent Monbillard.
2539 * collectd-nagios: The new `collectd-nagios' binary queries values
2540 from collectd, parses them and exits according to Nagios-standards.
2541 * manpages: The manpages have been improved a lot.
2543 2007-09-28, Version 3.11.7
2544 * wireless plugin: Correct the handling of cards returning signal and
2545 noise quality as percentage.
2547 2007-08-31, Version 3.11.6
2548 * processes plugin: Fix a potential segmentation fault.
2550 2007-05-29, Version 3.11.5
2551 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2552 * ntpd plugin: Fix a potential buffer overflow.
2553 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2554 were accounted as `zombies'.
2556 2007-04-10, Version 3.11.4
2557 * dns plugin: Change the order of includes to make the plugin compile
2560 2007-03-30, Version 3.11.3
2561 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2562 of the unused `COLLECT_KSTAT'.
2564 2007-02-11, Version 3.11.2
2565 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2566 NULL-pointer may have been passed to `printf' which causes a
2567 segfault with some libcs.
2569 2007-02-10, Version 3.11.1
2570 * df plugin: Some wrong defines have been fixed so the plugin works
2571 under Solaris again.
2572 * dns plugin: The usage of a struct has been fixed to work with
2574 * processes plugin: Some missing defines have been added so the plugin
2575 compiles cleanly under FreeBSD and presumably other UNIXes.
2577 2006-12-22, Version 3.11.0
2578 * collectd: The new command line option `-P' makes it easier for
2579 distributors to change the location of PID-files.
2580 * collectd: The daemon shuts down faster now which makes it easier to
2581 write init.d-scripts for it.
2582 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2583 caused problems every now and then.
2584 * df plugin: New config options allow to ignore certain mountpoints,
2585 filesystem types or devices.
2586 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2587 and interprets it. It collects traffic as well as qtype, opcode and
2589 * email plugin: Sebastian Harl has contributed this plugin which
2590 counts received mails in categories (e. g. ham, spam, virus), spam
2591 score (as given by SpamAssassin) and check types.
2592 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2593 uses `mbmon' to gather information from sensors on the motherboard.
2594 * processes plugin: Collect detailed statistics for configured
2595 processes, that's process and thread count, CPU usage, resident
2596 segment size and pagefaults.
2597 * multimeter plugin: Peter Holik contributed a new plugin which
2598 queries multimeters.
2599 * sensors plugin: Lubos Stanek has put much effort into improving this
2600 plugin, including `extended naming', collection of voltage values
2601 and the possibility to ignore certain values.
2603 2006-12-21, Version 3.10.4
2604 * Max Kellermann has identified a bug in the server routine: When
2605 opening a socket fails the daemon will (re)try opening the socket in
2606 an endless loop, ultimately leading to a `EMFILE' error.
2608 2006-11-04, Version 3.10.3
2609 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2610 ntpd's reply was sent in more than one packet, the buffer size was
2611 calculated incorrectly, resulting in the reading of uninitialized or
2614 2006-11-01, Version 3.10.2
2615 * The sample config file has been improved.
2616 * Errors in the manpages have been corrected.
2617 * The ping-plugin now adds hosts during initialization, not during
2618 startup. This speeds up startup when no network connectivity is
2619 available. Also, the hosts are being added later when the network is
2621 * Improved BSD-support for the df-plugin.
2622 * Fixed syntax errors in the swap-plugin for Mac OS X.
2623 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2625 * Don't disable the mysql-plugin if connecting to the database fails
2626 during initialization. Instead, try again in increasing intervals.
2628 2006-07-19, Version 3.10.1
2629 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2630 the apcups cannot be reached, unconnected sockets will pile up and
2631 eventually lead to `Too many open files' errors.
2633 2006-07-09, Version 3.10.0
2634 * The `disk' plugin has been ported to Darwin.
2635 * The `battery' plugin should work on many Apple computers now.
2636 * The `traffic' plugin can now ignore certain interfaces. Also,
2637 statistics for sent/received packets and errors have been added.
2638 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2639 to Anthony Gialluca for contributing this plugin and providing me
2640 with a test environment :)
2641 * A plugin for monitoring an NTP instance and the local clock drift
2644 2006-06-25, Version 3.9.4
2645 * The Solaris code in the `swap' plugin has been changed to reflect
2646 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2648 * The debugging system has been fixed to work with the Sun libc.
2649 * When built without librrd the variable `operating_mode' could be
2650 uninitialized. Thanks to David Elliot for reporting the bug.
2652 2006-06-01, Version 3.9.3
2653 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2654 operating systems also profit from the changes, but I wasn't able to
2656 * Changed the build system to find the netinet-includes under FreeBSD
2657 and therefore successfully build the `liboping' library there.
2659 2006-05-09, Version 3.9.2
2660 * Applied a patch to the `liboping' library. Due to a bug in the
2661 sequence checking the `ping' plugin stopped working after
2662 approximately 7.6 days.
2664 2006-05-09, Version 3.8.5
2665 * Applied a patch to the `liboping' library. Due to a bug in the
2666 sequence checking the `ping' plugin stopped working after
2667 approximately 7.6 days.
2669 2006-04-21, Version 3.9.1
2670 * Build issues with Solaris and possible other architectures have been
2672 * Problems when building the `apache'-plugin without `libcurl' have
2674 * A bug in the `ping' plugin has been fixed. Sorry folks.
2676 2006-04-02, Version 3.9.0
2677 * A plugin to monitor the Apache webserver has been added.
2678 <http://httpd.apache.org/>
2679 * A plugin to collect statistics about virtual servers using VServer.
2680 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2682 * A plugin for wireless LAN cards has been added. It monitors signal
2683 strength, link quality and noise ratio..
2684 * A plugin for Apple hardware sensors has been added.
2685 * An option to compile collectd with different `step' and `heartbeat'
2686 settings has been added. The size of RRAs is no longer static but
2687 calculated based on the settings for `step' and `width'.
2688 * The `ping' plugin can now be configured to use a certain TTL.
2689 * A plugin to monitor the hardware sensors of Apple computers has been
2691 * The plugins `cpu', `memory', `processes' and `traffic' have been
2692 ported to Mach/Darwin (Mac OS X).
2693 * The `log mode' has been contributed by Christophe Kalt. It writes
2694 the data into text files rather than RRD files.
2696 2006-04-09, Version 3.8.4
2697 * Applied patch by Vincent Stehlé which improves the disk-name
2698 resolution in the `hddtemp' plugin for Linux systems.
2700 2006-04-02, Version 3.8.3
2701 * Applied a patch by James Byers: The MySQL plugin was not working
2702 with MySQL 5.0.2 or later.
2704 2006-03-14, Version 3.8.2
2705 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2706 the GNU libc, because it points to `/etc/fstab' rather than
2709 2006-03-13, Version 3.8.1
2710 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2711 * Fixes in the debian `postinst' and `init.d' scripts.
2713 2006-03-09, Version 3.8.0
2714 * The `ping' plugin no longer uses `libping' but a self written
2715 library named `liboping'. With this library it's possible to ping
2716 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2718 2006-02-18, Version 3.7.2
2719 * A simple bug in the `battery' plugin has been fixed. It should now
2720 work with ACPI based batteries as well. Thanks to Sebastian for
2722 * Fixing a bug that prevented collectd to be built without librrd.
2723 Thanks to Werner Heuser for reporting it.
2725 2006-02-04, Version 3.7.1
2726 * The new network code has been improved to build with older versions
2728 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2729 to Tommie Gannert for this patch.
2731 2006-01-30, Version 3.7.0
2732 * The `battery' plugin has been added. It collects information about
2734 * The MySQL plugin has been improved: It now writes two more RRD
2735 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2736 * The `cpufreq' plugin now reads another file since the file it did
2737 read so far causes much overhead in the kernel. Also, you need root
2738 to read the old file, but not to read the new one.
2739 * The `hddtemp' plugin can now be configured to connect to another
2740 address and/or port than localhost.
2741 * The `df' plugin now prefers `statvfs' over `statfs'.
2742 * The network code has been rewritten. collectd now supports unicast
2743 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2744 be set in the configfile.
2746 2006-01-24, Version 3.6.2
2747 * Due to a bug in the configfile handling collectd wouldn't start in
2748 client mode. This released fixes this.
2750 2006-01-20, Version 3.6.1
2751 * Due to a bug in `configure.in' all modules and the binary were
2752 linked against `libmysqlclient'. This issue is solved by this
2755 2006-01-17, Version 3.6.0
2756 * A config file has been added. This allows for loading only specific
2758 * A `df' plugin has been added.
2759 * A `mysql' plugin has been added.
2760 * The `ping' plugin doesn't entirely give up hope when a socket error
2761 occurred, but will back of and increase the intervals between tries.
2763 2006-01-21, Version 3.5.2
2764 * Fixed yet another bug in the signal handling.. Stupid typo..
2765 * Improved the ping plugin to not give up on socket errors (backport
2768 2005-12-18, Version 3.5.1
2769 * The PID-file is now deleted correctly when shutting down the daemon.
2770 * SIGINT and SIGTERM are now handled correctly.
2772 2005-12-16, Version 3.5.0 (Revision 326)
2773 * A bug in the `load' module under Solaris has been fixed.
2774 * The `users' module has been contributed by Sebastian Harl. It counts
2775 currently logged in users.
2776 * The CPU module now works under FreeBSD without the use of
2777 `libstatgrab', however SMP support is missing.
2778 * The default directories for the RRD files and the PID file now
2779 depend on the compile time setting of `localstatedir'.
2781 2005-11-15, Version 3.4.0 (Revision 236)
2782 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2783 from gentoo's bugzilla for writing the patch.
2784 * The build dependency for librrd has been removed. Binaries built
2785 without librrd are client-only and will multicast their value as
2786 with the `-c' argument.
2787 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2788 * The newly introduced `-f' switch prevents daemon initialization
2789 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2790 Barcellos for this patch.
2792 2005-11-04, Version 3.3.0 (Revision 216)
2793 * New modules have been added:
2794 - `serial', for monitoring traffic on the serial interfaces
2795 - `nfs', for graphing NFS procedure calls
2796 - `tape', traffic from/to tape devices
2797 * The memory.rrd now accepts more than 4Gig of memory.
2799 2005-10-26, Version 3.2.0 (Revision 200)
2800 * Support for graphing the processes has been added (thanks to Lyonel
2802 * If reading from hddtemp fails collectd will increase the time
2803 between polls up to one day.
2804 * The init.d files have been improved.
2805 * Problems with the spec file have been fixed.
2807 2005-10-16, Version 3.1.0 (Revision 194)
2808 * Added the `setsid' syscall to the startup code.
2809 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2811 2005-09-30, Version 3.0.0 (Revision 184)
2812 * The ability to send/receive data to/from the network (think
2813 multicast) has been added.
2814 * Modules have been split up into shared libraries can be loaded at
2815 runtime. The biggest advantage is that the core program doesn't need
2816 to be linked against an external library.
2817 * A patch by George Kargiotakis has been applied: It fixes the sensors
2818 behaviour then more than one sensor is being queried.
2820 2005-09-16, Version 2.1.0 (Revision 172)
2821 * A module for swap statistics has been added.
2823 2005-09-09, Version 2.0.0 (Revision 135)
2824 * Filenames can no longer be configured at program startup. The only
2825 options as of this version are the directory and ping hosts.
2826 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2827 Soft-IRQ statistics are added to `System'.
2828 * Diskstats now collect read and write bytes, not sectors.
2829 * Ping statistics can now be collected for more than one host. There
2830 is no default any more: If no host is given no host will be pinged.
2831 * A self-written patch for libping has been applied so it builds
2834 2005-09-01, Version 1.8.1 (Revision 123)
2835 * Much improved configure-script: libraries and features may now be
2837 * More detailed warnings/error messages when RRD update fails.
2839 2005-08-29, Version 1.8.0:
2840 * Support for collecting disk statistics under Solaris.
2842 2005-08-25, Version 1.7.0:
2843 * Support for libstatgrab[1] for load, memory usage and network
2844 traffic. CPU- and disk-usage are not (yet) supported, since
2845 libstatgrab returns insufficient information. I will contact the
2847 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2848 aren't necessarily counted linear which is now handled correctly.
2849 [1]: http://www.i-scream.org/libstatgrab/
2851 2005-08-21, Version 1.6.0:
2852 * Basic support for Solaris: System load and cpu-usage can be
2853 collected under Solaris, too. Other stats will follow later.
2854 * Many fixes in the autoconf-script
2855 * Collection/Museum scripts have been added under contrib/museum
2856 * collectd may now be started in unprivileged mode, though ping
2857 statistics will not work.
2859 2005-07-17, Version 1.5.1:
2860 * Diskstats-RRDs now use major/minor for naming. Some systems have
2861 weird strings as disk-names..
2863 2005-07-17, Version 1.5:
2864 * A new module, diskstats, has been added. It collects information
2865 about the disks and partitions.
2867 2005-07-11, Version 1.4.2:
2868 * The meminfo module has been changed to work with more platforms
2869 and/or kernel versions.
2871 2005-07-10, Version 1.4.1: Correct traffic stats
2872 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2873 forgot to correct when I changed that module.
2875 2005-07-09, Version 1.4: More traffic stats
2876 * Traffic is now collected for all interfaces that can be found
2877 * Temperature-statistics are read from lm-sensors if available
2879 2005-07-08, Version 1.3: CPU stats
2880 * Collecting CPU statistics now
2882 2005-07-12, Version 1.2: Using syslog
2883 * collectd is now using the syslog facility to report errors, warnings
2885 * The default directory is now /var/db/collectd
2887 2005-07-10, Version 1.1: Minor changes
2888 * Nothing really useful to say ;)
2890 2005-07-09, Version 1.0: Initial Version
