1855 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1856 primarily BSDs, don't take it well and crash.
1857 * oracle plugin: Portability to 64 bit systems has been improved.
1858 * postgresql plugin: The default configuration has been improved.
1859 * rrdtool plugin: Fix a possible race condition: If the network plugin
1860 is brought and dispatches a value before the rrdtool plugin is
1861 initialized, the daemon may crash.
1863 2009-02-22, Version 4.6.1
1864 * collectd: Many documentation fixes.
1865 * Collectd::Unixsock: Error handling has been improved.
1866 * regex match: Don't link with the PCRE library.
1867 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
1868 for finding and fixing most of them.
1869 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1870 faults. Thanks to Peter Holik for his patch.
1872 2009-02-16, Version 4.6.0
1873 * collectd: Added the `filter chain' infrastructure, which allows the
1874 user to use `matches' and `targets' to control value processing.
1875 * collectd: The new `-T' command line argument allows more in-depth
1876 testing of a configuration. Thanks to Doug MacEachern for the patch.
1877 * collectd-nagios: The Nagios integration command has been updated to
1878 use libcollectdclient. The `percentage' aggregation function has
1879 been added. Thanks to Fabian Linzberger for the patch.

1881 unixsock plugin for clients has been added.
1882 * regex match: Match values by their identifies using regular
1884 * timediff match: Match for values with an invalid timestamp.
1885 * value match: Select values by their data sources' values.
1886 * notification target: Create and dispatch a notification.
1887 * replace target: Replace parts of an identifier using regular
1889 * set target: Set (overwrite) entire parts of an identifier.
1890 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1891 statistics, allowing very detailed name server statistics. Thanks to
1892 Bruno Prémont for this plugin.
1893 * cpu plugin: Report `interrupt' separately when using
1894 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1895 example for native OpenBSD support, has been added. Thanks to Simon
1896 Kuhnle for the patch.
1897 * csv plugin: Make it possible to write values to STDOUT instead of
1898 files. This is meant for testing purposes mostly. The output written
1899 to STDOUT is compatible with the exec plugin. Thanks to Doug
1900 MacEachern for the patch.
1901 * curl plugin: This new plugin can be used to read web pages and parse
1902 them using the same mechanism that's used in the tail plugin.
1903 * dbi plugin: This new plugin allows you to connect to a variety of
1904 relational databases and use SQL to gather custom statistics from
1905 it. It is similar to the already existing PostgreSQL plugin but uses
1906 libdbi to communicate with the database(s).
1907 * interface plugin: Use the ignorelist framework when selecting /
1908 ignoring interfaces. This allows one to use regular expressions to
1909 select interfaces, too.
1910 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1911 Thanks to Bruno Prémont for this patch.
1912 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1914 * mysql plugin: Allow connecting to a database via the UNIX domain
1915 socket, too. Thanks to Mirko Buffoni for the patch.
1916 * network plugin: Further performance improvements for the receive
1917 code. This hopefully will help very large setups.
1918 * openvpn plugin: This new plugin collects statistics provided by the
1919 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1920 * oracle plugin: This new plugin allows you to connect to an Oracle
1921 database and use SQL to gather custom statistics from it. It is
1922 similar to the already existing PostgreSQL plugin.
1923 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1925 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1926 * perl plugin: Added support for `notification meta data'.
1927 * perl plugin: Added support for the `filter chain' infrastructure by
1928 allowing plugins to register `matches' and `targets'.
1929 * postgresql plugin: The preferred configuration syntax has been
1930 updated to be in line with the syntax used by the new dbi and oracle
1931 plugins. The compatibility code for the old syntax is present.
1932 Support for the new `Result' blocks and the interval parameter has
1934 * processes plugin: Stacksize and virtual memory usage statistics have
1935 been added. Portability fixes.
1936 * rrdcached plugin: This new plugin uses the (still in development)
1937 RRD accelerator daemon, rrdcached. This daemon works very similar to
1938 the original rrdtool plugin of collectd, but adds some more nice
1940 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1943 2009-05-09, Version 4.5.4
1944 * Build system, various plugins: Many build fixes for FreeBSD,
1945 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1946 for many fixes and providing a build system for many platforms,
1947 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1948 providing an OpenBSD system.
1949 * collectd: Fix a potential race condition when creating directories.
1950 * battery plugin: Don't complain about a missing directory every

1954 Thorsten von Eicken for reporting this problem.
1955 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1956 Tomasz Pala for the patch.
1957 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1959 * rrdtool plugin: Fix a possible race condition: If the network plugin
1960 is initialized and dispatches a value before the rrdtool plugin is
1961 initialized, the daemon may crash.
1962 * memory plugin: Fix a potential problem under Solaris.
1964 2009-02-22, Version 4.5.3

1972 faults. Thanks to Peter Holik for his patch.
1973 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1974 code. Thanks to "thated" for reporting this.
1976 2009-01-02, Version 4.5.2
1977 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1978 file may be in both locations, especially when the database was
1979 installed in a non-standard path. Thanks to Dusty Doris for
1981 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1982 Solaris, in the configure script automatically.
1983 * build system, tcpconns plugin: Check for `kvm_nlist' and
1984 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1985 library with similar functions to the BSD variant, but doesn't
1986 provide these necessary functions.
1987 * collectd.conf(5): Various fixes and clarifications.
1988 * collectd: Remove a GNUism (unnamed unions), thus improving
1990 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1991 This solves portability problems, especially for Solaris.
1992 * dns plugin: Fix a portability problem with NetBSD.
1993 * filecount plugin: Fix an off-by-one error. This error may cause a
1995 * network plugin: Fix the handling of `type' in the network protocol.
1996 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1997 much larger buffer. This caused the `type' to be transferred much
1998 more often than necessary. In some cases, e. g. the `cpu' and
1999 `cpufreq' plugins being used at the same time, data may be corrupted
2000 in those files. Thanks to Bruno Prémont for debugging and reporting
2002 * processes plugin: Fix a possible segmentation fault when specifying
2003 invalid configuration options.
2004 * unixsock plugin: Make sure the initialization function is run only
2005 once. This resolves a file descriptor leak under systems which run
2006 the initialization more than once, such as Solaris.
2008 2008-10-16, Version 4.5.1
2009 * build system: Change `--enable-<plugin>' to abort with an error if
2010 dependencies are not met. Thanks to Bruno Prémont for the patch.
2011 Also, the poisoning of various string functions has been restricted
2013 * collectd: Fix a memory leak in the global value cache. With every
2014 *missing* value a couple of bytes would be leaked. Another memory
2015 leak in the configuration handling code has been fixed. Thanks to
2016 Niraj Tolia for reporting these issues.
2017 * collectd: Fix an off-by-one error in the ignorelist functionality.
2018 When using regular expressions, the last character would be missing,
2019 possibly matching differently from what one would expect.
2020 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2022 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2023 Linzberger for reporting the bug.
2024 * iptables plugin: Fix an off-by-one error. If a string was just one
2025 character too long, it was truncated instead of reporting an error.
2026 * network plugin: Fix a memory leak in the configuration handling
2027 code. Thanks to Niraj Tolia for reporting this issue.
2028 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2029 * postgresql plugin: Don't reopen connection during reinitialization.
2030 This fixes a bug under Solaris and potentially other platforms.
2031 Missing calls to `PQclear' have been added, too. This fixes memory
2032 leaks. Thanks to ``Admin'' for reporting these bugs.
2033 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2035 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2036 problems with some `libc's. Thanks to Matthias Lay for reporting the
2039 2008-09-04, Version 4.5.0
2040 * collectd: Added the ability to flush certain identifiers.
2041 * collectd: The concept of `notification meta data' has been
2043 * filecount plugin: The new filecount plugin counts the number of
2044 files in a directory and its subdirectories.
2045 * ipmi plugin: Sensor names have been changed to ensure unique names.
2046 Notifications upon added and removed sensors can now be generated.
2047 * notify_desktop plugin: This new plugin sends notifications to the
2048 X desktop using the structure defined in the `Desktop Notification
2050 * notify_email plugin: This new plugin sends out notifications via
2051 email, using the `esmtp' library.
2052 * onewire plugin: The new experimental(!) onewire plugin reads values,
2053 such as temperatures, from sensors connected to the computer via the
2055 * perl plugin: Improved synchronized access to internal data structures
2056 and fixed a possible dead-lock.
2057 * perl plugin: Added the ability to flush certain identifiers and marked
2058 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2060 * perl plugin: Added the ability to configure Perl plugins.
2061 * postgresql plugin: The new postgresql plugin collects statistics
2062 about or from a PostgreSQL database.
2063 * processes plugin: The `ProcessMatch' option has been added.
2064 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2066 * tcpconns plugin: This plugin has been ported to OpenBSD.
2067 * thermal plugin: The new thermal plugin collects system temperatures
2068 using Linux ACPI thermal zone data.
2070 2009-01-02, Version 4.4.5
2071 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2072 file may be in both locations, especially when the database was
2073 installed in a non-standard path. Thanks to Dusty Doris for
2075 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2076 Solaris, in the configure script automatically.
2077 * collectd.conf(5): Various fixes and clarifications.
2078 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2079 portability problems, especially for Solaris.
2080 * dns plugin: Fix a portability problem with NetBSD.
2081 * network plugin: Fix the handling of `type' in the network protocol.
2082 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2083 much larger buffer. This caused the `type' to be transferred much
2084 more often than necessary. In some cases, e. g. the `cpu' and
2085 `cpufreq' plugins being used at the same time, data may be corrupted
2086 in those files. Thanks to Bruno Prémont for debugging and reporting
2088 * unixsock plugin: Make sure the initialization function is run only
2089 once. This resolves a file descriptor leak under systems which run
2090 the initialization more than once, such as Solaris.
2092 2008-10-16, Version 4.4.4
2093 * build system: Change `--enable-<plugin>' to abort with an error if
2094 dependencies are not met. Thanks to Bruno Prémont for the patch.
2095 Also, the poisoning of various string functions has been restricted
2097 * collectd: Fix a memory leak in the global value cache. With every
2098 *missing* value a couple of bytes would be leaked. Another memory
2099 leak in the configuration handling code has been fixed. Thanks to
2100 Niraj Tolia for reporting these issues.
2101 * collectd: Fix an off-by-one error in the ignorelist functionality.
2102 When using regular expressions, the last character would be missing,
2103 possibly matching differently from what one would expect.
2104 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2106 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2107 Linzberger for reporting the bug.

2109 code. Thanks to Niraj Tolia for reporting this issue.
2110 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2111 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2112 problems with some `libc's. Thanks to Matthias Lay for reporting the
2115 2008-09-01, Version 4.4.3
2116 * collectd: Fix a memory leak in the threshold checking code.
2117 * memcached plugin: Fix a too short timeout and a related file
2119 * memory plugin: A typo in the libstatgrab code has been fixed.
2120 * snmp plugin: Fix a possible memory leak.
2122 2008-07-15, Version 4.4.2
2123 * build system: Use pkg-config to detect the upsclient library.
2124 * collectd: Try even harder to determine the endianness of the
2125 architecture collectd is being built on.
2126 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2128 * dns plugin: Fix compilation errors with BIND versions 19991001
2130 * network plugin: Bugfix in the init routine: The init function
2131 cleared a buffer regardless of its contents. This could lead to lost
2132 values under Solaris.
2133 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2134 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2136 * wireless plugin: Work around incorrect noise and power values
2137 returned by some broken drivers.
2139 2008-06-03, Version 4.4.1
2140 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2141 to kyrone for reporting this.
2142 * collectd: Fixed min/max output in notifications generated by
2144 * collectd-nagios: Fix the protocol used to communicate with the
2146 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2147 initialization has errors. An issue with Perl 5.10 has been fixed.
2148 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2149 René Rebe and Siegmund Gorr for reporting this.
2151 2008-05-06, Version 4.4.0
2152 * collectd: Internal code cleanups.
2153 * collectd: Added support for a `Flush' command in the unixsock and
2154 exec plugins. This command can be used to force a plugin (or all) to
2155 flush its values to disk.
2156 * collectd: Thresholds can now be configured to apply to one data
2157 source only, making it possible to configure different thresholds
2158 for each data source.
2159 * apache, nginx plugins: Added the possibility to disable host and/or
2161 * ascent plugin: The new ascent plugin reads and parses the statistics
2162 page of an Ascent server.
2163 * cpu plugin: Support for the statgrab library has been added.
2164 * disk plugin: The possibility to ignore certain disks or collect only
2165 specific disks has been added.

2174 authoritative or a recursing PowerDNS name server.
2175 * rrdtool plugin: The size of the files generated with the default
2176 configuration has been decreased.
2177 * tail plugin: The new tail plugin can be used to gather statistics by
2178 continuously reading from log files.
2179 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2180 TeamSpeak2 server and collects statistics about the number of users
2181 and number of channels.
2182 * users plugin: Support for the statgrab library has been added.
2183 * vmem plugin: The new vmem plugin collects very detailed statistics
2184 about the virtual memory subsystem of Linux.
2186 2008-08-30, Version 4.3.4
2187 * Build system: Improved detection of and linking with the statgrab

2208 if the libc expects it.
2209 * collectd: Error and warning messages have been improved.
2210 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2212 * apache plugin: Allocate new memory when reading a webpage instead of
2213 using a buffer of static size.
2214 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2216 * hddtemp plugin: Error and warning messages have been improved.
2217 * sensors plugin: Fix sensor collection for some chip types.
2219 2008-03-29, Version 4.3.2

2225 * unixsock plugin: Fix mixed input and output operation on streams.
2226 * wireless plugin: Fix reading noise value.
2228 2008-03-05, Version 4.3.1
2229 * exec plugin: Set supplementary group IDs.
2231 + Use `memcpy' when constructing/parsing a package to avoid
2232 alignment problems on weird architectures, such as Sparc.
2233 + Translate doubles to/from the x86 byte representation to ensure
2234 cross-platform compatibility.
2235 * ping plugin: Correct the handling of the `TTL' setting.
2236 * swap plugin: Reapply a patch for Solaris.
2237 * tcpconns plugin: Portability improvements.
2239 2008-02-18, Version 4.3.0
2240 * collectd: Notifications have been added to the daemon. Notifications
2241 are status messages that may be associated with a data instance.
2242 * collectd: Threshold checking has been added to the daemon. This
2243 means that you can configure threshold values for each data
2244 instance. If this threshold is exceeded a notification will be
2246 * collectd: The new `FQDNLookup' option tells the daemon to use the
2247 full qualified domain name as the hostname, not just the host part
2248 es returned by `gethostname(2)'.
2249 * collectd: Support for more than one `TypesDB' file has been added.
2250 This is useful when one such file is included in a package but one
2251 wants to add custom type definitions.
2252 * collectd: The `Include' config option has been expanded to handle
2253 entire directories and shell wildcards.
2254 * collectdmon: The new `collectdmon' binary detects when collectd
2255 terminates and automatically restarts it again.
2256 * csv plugin: The CSV plugin is now able to store counter values as a
2257 rate, using the `StoreRates' configuration option.
2258 * exec plugin: Handling of notifications has been added and the
2259 ability to pass arguments to the executed programs has been added.
2260 * hddtemp plugin: The new `TranslateDevicename' option lets you
2261 disable the translation from device names to major-minor-numbers.
2262 * logfile plugin: Handling of notifications has been added.
2263 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2264 domain name lookups in this plugin.
2265 * perl plugin: Many internal changes added support for handling multiple
2266 threads making the plugin reasonably usable inside collectd. The API has
2267 been extended to support notifications and export global variables to
2268 Perl plugins; callbacks now have to be identified by name rather than a
2269 pointer to a subroutine. The plugin is no longer experimental.
2270 * uuid plugin: The new UUID plugin sets the hostname to an unique
2271 identifier for this host. This is meant for setups where each client
2272 may migrate to another physical host, possibly going through one or
2273 more name changes in the process. Thanks to Richard Jones from
2274 Red Hat's Emerging Technology group for this plugin.
2275 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2276 CPU, disk and network statistics about guest systems on the same
2277 physical server. Thanks to Richard Jones from Red Hat's Emerging
2278 Technology group for this plugin.
2280 2008-04-22, Version 4.2.7
2281 * build system: Improved detection of several libraries, especially if
2282 they are in non-standard paths.
2283 * build system: Portability fixes: Automatically define "_REENTRANT"
2284 if the libc expects it.
2285 * collectd: Error and warning messages have been improved.
2286 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before

2302 * apache plugin: Improved initialization and error messages.
2303 * exec plugin: Set supplementary group IDs.
2305 + Create separate threads for reading from the socket and parsing
2306 and dispatching incoming packets. Versions prior to this may have
2307 problems in high-load situations, where the socket receive buffers
2308 overflows, resulting in gaps in the data.
2309 + Use `memcpy' when constructing/parsing a package to avoid
2310 alignment problems on weird architectures, such as Sparc.
2311 + Translate doubles to/from the x86 byte representation to ensure
2312 cross-platform compatibility.
2313 * ping plugin: Correct the handling of the `TTL' setting.
2314 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2315 * swap plugin: Reapply a patch for Solaris.

2318 2008-01-21, Version 4.2.4
2319 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2320 the permission on the socket as documented in the manpage. Thanks to
2321 Evgeny Chukreev for fixing this issue.
2322 * collectd: The documentation has been improved.
2324 2007-12-28, Version 4.2.3
2325 * sensors plugin: Updated the plugin to build and work with version 3
2326 of the libsensors library.
2328 2007-12-15, Version 4.2.2
2329 * nginx plugin: Incorrect comparison of strings lead to a segfault
2330 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2332 * logfile plugin: The config option `Timestamp' was handled
2333 incorrectly and basically always active. Thanks to Luke Heberling
2336 2007-11-08, Version 4.2.1
2337 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2338 enabled on the host.
2339 * snmp plugin: Fix a memory leak.
2341 2007-10-27, Version 4.2.0
2342 * collectd: The new config option `Include' lets you include other
2343 configfiles and thus split up your config into smaller parts. This
2344 may be especially interesting for the snmp plugin to keep the data
2345 definitions separate from the host definitions.
2346 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2347 (number of connections, octets and packets for each service and
2348 destination). Thanks to Sebastian Harl for this plugin.
2349 * memcached plugin: The new `memcached' plugin connects to a memcached
2350 daemon process and collects statistics of this distributed caching
2351 system. Thanks to Antony Dovgal for contributing this plugin.
2352 * nginx plugin: The new `nginx' plugin reads the status page of an
2353 nginx daemon and saves the handled connections and requests.
2354 * perl plugin: Many changes, including the added `EnableDebugger'
2355 config option which lets you debug your Perl plugins more easily.
2356 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2357 be more thread-safe otherwise by locking calls to the library.
2358 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2359 correct the values returned by SNMP-agents. If a <data> block is
2360 defined as `table' the instance is now optional. The sequence number
2361 is used as the type-instance in this case. The new `InstancePrefix'
2362 option allows to add arbitrary prefixes to the type-instance.
2363 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2364 certain TCP connections and what state they're in. This can be used
2365 to see how many connections your FTP server has to handle or how
2366 many outgoing connections your mailserver has open.
2368 2008-01-11, Version 4.1.6
2369 * unixsock plugin: A bug in the unixsock plugin caused it not to set

2378 of the libsensors library.
2380 2007-11-08, Version 4.1.4
2381 * Build system: Improve detection of the rrd library, especially if
2382 it's in a non-standard location.
2383 * Build system: A bug when parsing the argument for
2384 `--with-libnetsnmp' has been fixed.
2385 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2386 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2387 a deadlock or delay when shutting down the daemon.
2388 * snmp plugin: Fix a memory leak.
2390 2007-10-24, Version 4.1.3
2391 * collectd: A build issue under Solaris has been resolved by renaming
2393 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2394 be more thread-safe otherwise by locking calls to the library.
2396 2007-09-28, Version 4.1.2
2397 * apcups plugin: Fix reporting of the `load percent' data.
2398 * wireless plugin: Correct the handling of cards returning signal and
2399 noise quality as percentage.
2400 * perl plugin: Fix a possible buffer overflow in get_module_name().
2401 * build system: Further improve the detection of libraries.
2402 * netlink plugin: Build issues under some older versions of the Linux
2403 includes (i. e. Debian Sarge) have been fixed.
2404 * snmp plugin: Fix a potential segfault when a host times out. Add
2405 support for the `timeticks' type.
2407 2007-09-12, Version 4.1.1
2408 * Build system: The detection of `libnetlink' has been improved.
2409 * collectd: The documentation has been fixed in numerous places.
2410 * exec plugin: Setting the group under which to run a program has been
2412 * collectd: The `sstrerror' function was improved to work correctly
2413 with the broken GNU version of `strerror_r'.
2414 * collectd: Write an error message to STDERR when loading of a plugin
2416 * apcups plugin: Fix the `types' used to submit the values: They still
2417 has an `apcups_' prefix which doesn't work anymore.
2418 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2419 whatever the client thinks is `now'..
2421 2007-09-01, Version 4.1.0
2422 * Build system: The build system has been changed to automatically
2423 disable all plugins, which are missing dependencies. The dependency
2424 checking has been removed from the plugins themselves to remove
2426 * Flexible interval: The interval of collected data is now sent along
2427 with the data itself over the network, so that the interval-settings
2428 of server and clients no longer needs to match.
2429 * netlink plugin: The new `netlink' plugin connects to the Linux
2430 kernel using a netlink socket and uses it to query information about
2431 interfaces, qdiscs and classes.
2432 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2433 to not block data collection.
2434 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2435 network devices, such as switches, routers, thermometers, rack
2436 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2438 * unixsock plugin: Added the `LISTVAL' command.
2439 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2440 of music played with xmms.
2442 2007-09-28, Version 4.0.9
2443 * apcups plugin: Fix reporting of the `load percent' data.
2444 * wireless plugin: Correct the handling of cards returning signal and
2445 noise quality as percentage.
2446 * perl plugin: Fix a possible buffer overflow in get_module_name().
2448 2007-09-12, Version 4.0.8
2449 * collectd: The `sstrerror' function was improved to work correctly
2450 with the broken GNU version of `strerror_r'.
2451 * collectd: Write an error message to STDERR when loading of a plugin
2453 * apcups plugin: Fix the `types' used to submit the values: They still
2454 has an `apcups_' prefix which doesn't work anymore.
2455 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2456 whatever the client thinks is `now'..
2458 2007-08-26, Version 4.0.7
2459 * documentation: Some typos have been fixed and some information has
2461 * build system: Many fixes for detecting libraries in unusual places,
2462 such as on RedHat systems. The affected libraries are `libcurl',
2463 `libmysql', and `libupsclient'.
2464 * network plugin: Allow the `Port' option to be specified as a number
2465 (i. e. without quotes).
2466 * nut plugin: A fix allows linking the nut plugin against
2467 libupsclient, version >= 2.2.0.
2468 * processes plugin: Fix a potential segmentation fault.
2470 2007-07-30, Version 4.0.6
2471 * sensors plugin: Fix the ignorelist functionality: Only the `type
2472 instance' was used to match against the list, but the documentation
2473 told otherwise. This release fixes the code, so it complies with the
2475 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2476 configuration messages will end up in the logging facility.
2477 * conrtib/fedora: The contributed specfile for Fedora has been
2480 2007-07-05, Version 4.0.5
2481 * Portability: More fixes for OpenBSD have been included.
2483 2007-06-24, Version 4.0.4
2484 * cpu plugin: Fixed the Solaris code.
2485 * dns plugin: Fixed a build issue for OpenBSD.
2486 * interface plugin: Fixed the Solaris code.
2487 * load plugin: Fixed the alternative `/proc' Linux code.
2488 * memory plugin: Fixed the Solaris code.
2489 * oconfig: Don't require `-lfl' anymore.
2491 2007-06-19, Version 4.0.3
2492 * cpu plugin: Fix the Darwin / Mac OS X code.
2493 * ping plugin: Use the return value of `getpid', not its address.
2494 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2495 initialized correctly.
2496 * configure: Added `--with-nan-emulation' to aid cross compilation.
2498 2007-06-12, Version 4.0.2
2499 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2500 they're given in numerically form.
2502 2007-06-07, Version 4.0.1
2503 * iptables plugin: A bug in the configuration routine has been fixed.
2504 Setting a comment in the configfile will no longer cause a
2507 2007-06-03, Version 4.0.0
2508 * collectd: The plugin-infrastructure has been changed to allow for
2509 more types of plugins, namely `write' and `log' plugins.
2510 * collectd: The read-function has been changed to read many plugins in
2511 parallel, using threads. Thus, plugins generally need to use
2512 thread-safe functions from now on.
2513 * collectd: The '-t' command line options allows to perform syntax tests
2514 of the configuration file and exit immediately.
2515 * csv plugin: The new `csv' plugin handles output to `comma separated
2517 * rrdtool plugin: The new `rrdtool' plugin handles output to
2518 RRD-files. Data can be cached to combine multiple updates into one
2519 write to increase IO-performance.
2520 * network plugin: The new `network' plugin handles IO via the network.
2521 It implements a different, much more extensible protocol which can
2522 combine many values in one packet, decreasing the number of UDP-
2523 packets being sent. It can read from and send to the network and
2524 with the appropriate configuration even forward packets to other
2526 * unixsock plugin: The new `unixsock' plugin provides an interface to
2527 communicate with the daemon while it is running. Right now the
2528 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2530 * perl plugin: The new `perl' plugin allows you to write extensions
2531 for collectd in the scripting-language Perl.
2532 * logfile plugin: The new `logfile' plugin writes logmessages to files
2533 or STDOUT or STDERR.
2534 * syslog plugin: The new `syslog' plugin sends logmessages to the
2535 system's syslog daemon.
2536 * entropy plugin: The new `entropy' plugin collects the amount of
2537 entropy currently being available to the system.
2538 * exec plugin: The new `exec' plugin forks child processes and reads
2539 back values provided by the forked processes.
2540 * iptables plugin: The new `iptables' plugin reads counters from
2541 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2543 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2544 to Peter Holik for contributing this plugin.
2545 * nut plugin: The new `nut' plugin connects the upsd of the `network
2546 ups tools' and reads information about the connected UPS.
2547 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2548 connections) field was added by Florent Monbillard.
2549 * collectd-nagios: The new `collectd-nagios' binary queries values
2550 from collectd, parses them and exits according to Nagios-standards.
2551 * manpages: The manpages have been improved a lot.
2553 2007-09-28, Version 3.11.7
2554 * wireless plugin: Correct the handling of cards returning signal and
2555 noise quality as percentage.
2557 2007-08-31, Version 3.11.6
2558 * processes plugin: Fix a potential segmentation fault.
2560 2007-05-29, Version 3.11.5
2561 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2562 * ntpd plugin: Fix a potential buffer overflow.
2563 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2564 were accounted as `zombies'.
2566 2007-04-10, Version 3.11.4
2567 * dns plugin: Change the order of includes to make the plugin compile
2570 2007-03-30, Version 3.11.3
2571 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2572 of the unused `COLLECT_KSTAT'.
2574 2007-02-11, Version 3.11.2
2575 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2576 NULL-pointer may have been passed to `printf' which causes a
2577 segfault with some libcs.
2579 2007-02-10, Version 3.11.1
2580 * df plugin: Some wrong defines have been fixed so the plugin works
2581 under Solaris again.
2582 * dns plugin: The usage of a struct has been fixed to work with
2584 * processes plugin: Some missing defines have been added so the plugin
2585 compiles cleanly under FreeBSD and presumably other UNIXes.
2587 2006-12-22, Version 3.11.0
2588 * collectd: The new command line option `-P' makes it easier for
2589 distributors to change the location of PID-files.
2590 * collectd: The daemon shuts down faster now which makes it easier to
2591 write init.d-scripts for it.
2592 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2593 caused problems every now and then.
2594 * df plugin: New config options allow to ignore certain mountpoints,
2595 filesystem types or devices.
2596 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2597 and interprets it. It collects traffic as well as qtype, opcode and
2599 * email plugin: Sebastian Harl has contributed this plugin which
2600 counts received mails in categories (e. g. ham, spam, virus), spam
2601 score (as given by SpamAssassin) and check types.
2602 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2603 uses `mbmon' to gather information from sensors on the motherboard.
2604 * processes plugin: Collect detailed statistics for configured
2605 processes, that's process and thread count, CPU usage, resident
2606 segment size and pagefaults.
2607 * multimeter plugin: Peter Holik contributed a new plugin which
2608 queries multimeters.
2609 * sensors plugin: Lubos Stanek has put much effort into improving this
2610 plugin, including `extended naming', collection of voltage values
2611 and the possibility to ignore certain values.
2613 2006-12-21, Version 3.10.4
2614 * Max Kellermann has identified a bug in the server routine: When
2615 opening a socket fails the daemon will (re)try opening the socket in
2616 an endless loop, ultimately leading to a `EMFILE' error.
2618 2006-11-04, Version 3.10.3
2619 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2620 ntpd's reply was sent in more than one packet, the buffer size was
2621 calculated incorrectly, resulting in the reading of uninitialized or
2624 2006-11-01, Version 3.10.2
2625 * The sample config file has been improved.
2626 * Errors in the manpages have been corrected.
2627 * The ping-plugin now adds hosts during initialization, not during
2628 startup. This speeds up startup when no network connectivity is
2629 available. Also, the hosts are being added later when the network is
2631 * Improved BSD-support for the df-plugin.
2632 * Fixed syntax errors in the swap-plugin for Mac OS X.
2633 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2635 * Don't disable the mysql-plugin if connecting to the database fails
2636 during initialization. Instead, try again in increasing intervals.
2638 2006-07-19, Version 3.10.1
2639 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2640 the apcups cannot be reached, unconnected sockets will pile up and
2641 eventually lead to `Too many open files' errors.
2643 2006-07-09, Version 3.10.0
2644 * The `disk' plugin has been ported to Darwin.
2645 * The `battery' plugin should work on many Apple computers now.
2646 * The `traffic' plugin can now ignore certain interfaces. Also,
2647 statistics for sent/received packets and errors have been added.
2648 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2649 to Anthony Gialluca for contributing this plugin and providing me
2650 with a test environment :)
2651 * A plugin for monitoring an NTP instance and the local clock drift
2654 2006-06-25, Version 3.9.4
2655 * The Solaris code in the `swap' plugin has been changed to reflect
2656 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2658 * The debugging system has been fixed to work with the Sun libc.
2659 * When built without librrd the variable `operating_mode' could be
2660 uninitialized. Thanks to David Elliot for reporting the bug.
2662 2006-06-01, Version 3.9.3
2663 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2664 operating systems also profit from the changes, but I wasn't able to
2666 * Changed the build system to find the netinet-includes under FreeBSD
2667 and therefore successfully build the `liboping' library there.
2669 2006-05-09, Version 3.9.2
2670 * Applied a patch to the `liboping' library. Due to a bug in the
2671 sequence checking the `ping' plugin stopped working after
2672 approximately 7.6 days.
2674 2006-05-09, Version 3.8.5
2675 * Applied a patch to the `liboping' library. Due to a bug in the
2676 sequence checking the `ping' plugin stopped working after
2677 approximately 7.6 days.
2679 2006-04-21, Version 3.9.1
2680 * Build issues with Solaris and possible other architectures have been
2682 * Problems when building the `apache'-plugin without `libcurl' have
2684 * A bug in the `ping' plugin has been fixed. Sorry folks.
2686 2006-04-02, Version 3.9.0
2687 * A plugin to monitor the Apache webserver has been added.
2688 <http://httpd.apache.org/>
2689 * A plugin to collect statistics about virtual servers using VServer.
2690 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2692 * A plugin for wireless LAN cards has been added. It monitors signal
2693 strength, link quality and noise ratio..
2694 * A plugin for Apple hardware sensors has been added.
2695 * An option to compile collectd with different `step' and `heartbeat'
2696 settings has been added. The size of RRAs is no longer static but
2697 calculated based on the settings for `step' and `width'.
2698 * The `ping' plugin can now be configured to use a certain TTL.
2699 * A plugin to monitor the hardware sensors of Apple computers has been
2701 * The plugins `cpu', `memory', `processes' and `traffic' have been
2702 ported to Mach/Darwin (Mac OS X).
2703 * The `log mode' has been contributed by Christophe Kalt. It writes
2704 the data into text files rather than RRD files.
2706 2006-04-09, Version 3.8.4
2707 * Applied patch by Vincent Stehlé which improves the disk-name
2708 resolution in the `hddtemp' plugin for Linux systems.
2710 2006-04-02, Version 3.8.3
2711 * Applied a patch by James Byers: The MySQL plugin was not working
2712 with MySQL 5.0.2 or later.
2714 2006-03-14, Version 3.8.2
2715 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2716 the GNU libc, because it points to `/etc/fstab' rather than
2719 2006-03-13, Version 3.8.1
2720 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2721 * Fixes in the debian `postinst' and `init.d' scripts.
2723 2006-03-09, Version 3.8.0
2724 * The `ping' plugin no longer uses `libping' but a self written
2725 library named `liboping'. With this library it's possible to ping
2726 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2728 2006-02-18, Version 3.7.2
2729 * A simple bug in the `battery' plugin has been fixed. It should now
2730 work with ACPI based batteries as well. Thanks to Sebastian for
2732 * Fixing a bug that prevented collectd to be built without librrd.
2733 Thanks to Werner Heuser for reporting it.
2735 2006-02-04, Version 3.7.1
2736 * The new network code has been improved to build with older versions
2738 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2739 to Tommie Gannert for this patch.
2741 2006-01-30, Version 3.7.0
2742 * The `battery' plugin has been added. It collects information about
2744 * The MySQL plugin has been improved: It now writes two more RRD
2745 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2746 * The `cpufreq' plugin now reads another file since the file it did
2747 read so far causes much overhead in the kernel. Also, you need root
2748 to read the old file, but not to read the new one.
2749 * The `hddtemp' plugin can now be configured to connect to another
2750 address and/or port than localhost.
2751 * The `df' plugin now prefers `statvfs' over `statfs'.
2752 * The network code has been rewritten. collectd now supports unicast
2753 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2754 be set in the configfile.
2756 2006-01-24, Version 3.6.2
2757 * Due to a bug in the configfile handling collectd wouldn't start in
2758 client mode. This released fixes this.
2760 2006-01-20, Version 3.6.1
2761 * Due to a bug in `configure.in' all modules and the binary were
2762 linked against `libmysqlclient'. This issue is solved by this
2765 2006-01-17, Version 3.6.0
2766 * A config file has been added. This allows for loading only specific
2768 * A `df' plugin has been added.
2769 * A `mysql' plugin has been added.
2770 * The `ping' plugin doesn't entirely give up hope when a socket error
2771 occurred, but will back of and increase the intervals between tries.
2773 2006-01-21, Version 3.5.2
2774 * Fixed yet another bug in the signal handling.. Stupid typo..
2775 * Improved the ping plugin to not give up on socket errors (backport
2778 2005-12-18, Version 3.5.1
2779 * The PID-file is now deleted correctly when shutting down the daemon.
2780 * SIGINT and SIGTERM are now handled correctly.
2782 2005-12-16, Version 3.5.0 (Revision 326)
2783 * A bug in the `load' module under Solaris has been fixed.
2784 * The `users' module has been contributed by Sebastian Harl. It counts
2785 currently logged in users.
2786 * The CPU module now works under FreeBSD without the use of
2787 `libstatgrab', however SMP support is missing.
2788 * The default directories for the RRD files and the PID file now
2789 depend on the compile time setting of `localstatedir'.
2791 2005-11-15, Version 3.4.0 (Revision 236)
2792 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2793 from gentoo's bugzilla for writing the patch.
2794 * The build dependency for librrd has been removed. Binaries built
2795 without librrd are client-only and will multicast their value as
2796 with the `-c' argument.
2797 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2798 * The newly introduced `-f' switch prevents daemon initialization
2799 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2800 Barcellos for this patch.
2802 2005-11-04, Version 3.3.0 (Revision 216)
2803 * New modules have been added:
2804 - `serial', for monitoring traffic on the serial interfaces
2805 - `nfs', for graphing NFS procedure calls
2806 - `tape', traffic from/to tape devices
2807 * The memory.rrd now accepts more than 4Gig of memory.
2809 2005-10-26, Version 3.2.0 (Revision 200)
2810 * Support for graphing the processes has been added (thanks to Lyonel
2812 * If reading from hddtemp fails collectd will increase the time
2813 between polls up to one day.
2814 * The init.d files have been improved.
2815 * Problems with the spec file have been fixed.
2817 2005-10-16, Version 3.1.0 (Revision 194)
2818 * Added the `setsid' syscall to the startup code.
2819 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2821 2005-09-30, Version 3.0.0 (Revision 184)
2822 * The ability to send/receive data to/from the network (think
2823 multicast) has been added.
2824 * Modules have been split up into shared libraries can be loaded at
2825 runtime. The biggest advantage is that the core program doesn't need
2826 to be linked against an external library.
2827 * A patch by George Kargiotakis has been applied: It fixes the sensors
2828 behaviour then more than one sensor is being queried.
2830 2005-09-16, Version 2.1.0 (Revision 172)
2831 * A module for swap statistics has been added.
2833 2005-09-09, Version 2.0.0 (Revision 135)
2834 * Filenames can no longer be configured at program startup. The only
2835 options as of this version are the directory and ping hosts.
2836 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2837 Soft-IRQ statistics are added to `System'.
2838 * Diskstats now collect read and write bytes, not sectors.
2839 * Ping statistics can now be collected for more than one host. There
2840 is no default any more: If no host is given no host will be pinged.
2841 * A self-written patch for libping has been applied so it builds
2844 2005-09-01, Version 1.8.1 (Revision 123)
2845 * Much improved configure-script: libraries and features may now be
2847 * More detailed warnings/error messages when RRD update fails.
2849 2005-08-29, Version 1.8.0:
2850 * Support for collecting disk statistics under Solaris.
2852 2005-08-25, Version 1.7.0:
2853 * Support for libstatgrab[1] for load, memory usage and network
2854 traffic. CPU- and disk-usage are not (yet) supported, since
2855 libstatgrab returns insufficient information. I will contact the
2857 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2858 aren't necessarily counted linear which is now handled correctly.
2859 [1]: http://www.i-scream.org/libstatgrab/
2861 2005-08-21, Version 1.6.0:
2862 * Basic support for Solaris: System load and cpu-usage can be
2863 collected under Solaris, too. Other stats will follow later.
2864 * Many fixes in the autoconf-script
2865 * Collection/Museum scripts have been added under contrib/museum
2866 * collectd may now be started in unprivileged mode, though ping
2867 statistics will not work.
2869 2005-07-17, Version 1.5.1:
2870 * Diskstats-RRDs now use major/minor for naming. Some systems have
2871 weird strings as disk-names..
2873 2005-07-17, Version 1.5:
2874 * A new module, diskstats, has been added. It collects information
2875 about the disks and partitions.
2877 2005-07-11, Version 1.4.2:
2878 * The meminfo module has been changed to work with more platforms
2879 and/or kernel versions.
2881 2005-07-10, Version 1.4.1: Correct traffic stats
2882 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2883 forgot to correct when I changed that module.
2885 2005-07-09, Version 1.4: More traffic stats
2886 * Traffic is now collected for all interfaces that can be found
2887 * Temperature-statistics are read from lm-sensors if available
2889 2005-07-08, Version 1.3: CPU stats
2890 * Collecting CPU statistics now
2892 2005-07-12, Version 1.2: Using syslog
2893 * collectd is now using the syslog facility to report errors, warnings
2895 * The default directory is now /var/db/collectd
2897 2005-07-10, Version 1.1: Minor changes
2898 * Nothing really useful to say ;)
2900 2005-07-09, Version 1.0: Initial Version
2901 * The following modules are provided:
