1063 added to the Linux implementation. Thanks to Darrell Bishop for his
1064 patch.

1777 * value match: Select values by their data sources' values.
1778 * notification target: Create and dispatch a notification.
1779 * replace target: Replace parts of an identifier using regular
1780 expressions.
1781 * set target: Set (overwrite) entire parts of an identifier.
1782 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
1783 statistics, allowing very detailed name server statistics. Thanks to
1784 Bruno Prémont for this plugin.
1785 * cpu plugin: Report `interrupt' separately when using
1786 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1787 example for native OpenBSD support, has been added. Thanks to Simon
1788 Kuhnle for the patch.
1789 * csv plugin: Make it possible to write values to STDOUT instead of
1790 files. This is meant for testing purposes mostly. The output written
1791 to STDOUT is compatible with the exec plugin. Thanks to Doug
1792 MacEachern for the patch.
1793 * curl plugin: This new plugin can be used to read web pages and parse
1794 them using the same mechanism that's used in the tail plugin.
1795 * dbi plugin: This new plugin allows you to connect to a variety of
1796 relational databases and use SQL to gather custom statistics from
1797 it. It is similar to the already existing PostgreSQL plugin but uses
1798 libdbi to communicate with the database(s).
1799 * interface plugin: Use the ignorelist framework when selecting /
1800 ignoring interfaces. This allows one to use regular expressions to
1801 select interfaces, too.
1802 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1803 Thanks to Bruno Prémont for this patch.
1804 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
1805 for the patch.
1806 * mysql plugin: Allow connecting to a database via the UNIX domain
1807 socket, too. Thanks to Mirko Buffoni for the patch.
1808 * network plugin: Further performance improvements for the receive
1809 code. This hopefully will help very large setups.
1810 * openvpn plugin: This new plugin collects statistics provided by the
1811 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
1812 * oracle plugin: This new plugin allows you to connect to an Oracle
1813 database and use SQL to gather custom statistics from it. It is
1814 similar to the already existing PostgreSQL plugin.
1815 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
1816 have been added.
1817 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1818 * perl plugin: Added support for `notification meta data'.
1819 * perl plugin: Added support for the `filter chain' infrastructure by
1820 allowing plugins to register `matches' and `targets'.
1821 * postgresql plugin: The preferred configuration syntax has been
1822 updated to be in line with the syntax used by the new dbi and oracle
1823 plugins. The compatibility code for the old syntax is present.
1824 Support for the new `Result' blocks and the interval parameter has
1825 been added.
1826 * processes plugin: Stacksize and virtual memory usage statistics have
1827 been added. Portability fixes.
1828 * rrdcached plugin: This new plugin uses the (still in development)
1829 RRD accelerator daemon, rrdcached. This daemon works very similar to
1830 the original rrdtool plugin of collectd, but adds some more nice
1831 features.
1832 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1833 added.
1835 2009-05-09, Version 4.5.4
1836 * Build system, various plugins: Many build fixes for FreeBSD,
1837 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1838 for many fixes and providing a build system for many platforms,
1839 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1840 providing an OpenBSD system.
1841 * collectd: Fix a potential race condition when creating directories.
1842 * battery plugin: Don't complain about a missing directory every
1843 interval.
1844 * dns plugin: Slight portability fixes.
1845 * exec plugin: Allow executed programs to close STDERR. Thanks to
1846 Thorsten von Eicken for reporting this problem.
1847 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1848 Tomasz Pala for the patch.
1849 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1850 the patch.
1851 * rrdtool plugin: Fix a possible race condition: If the network plugin
1852 is initialized and dispatches a value before the rrdtool plugin is
1853 initialized, the daemon may crash.
1854 * memory plugin: Fix a potential problem under Solaris.
1856 2009-02-22, Version 4.5.3
1857 * build system: The check for libupsclient even when `pkg-config' is
1858 not available.
1859 * collectd: Fix error handling in the global cache.
1860 * Collectd::Unixsock: Error handling has been improved.
1861 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
1862 patch.
1863 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1864 faults. Thanks to Peter Holik for his patch.
1865 * tcpconns plugin: An endianness problem has been fixed in the *BSD
1866 code. Thanks to "thated" for reporting this.
1868 2009-01-02, Version 4.5.2
1869 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1870 file may be in both locations, especially when the database was
1871 installed in a non-standard path. Thanks to Dusty Doris for
1872 reporting this.
1873 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1874 Solaris, in the configure script automatically.
1875 * build system, tcpconns plugin: Check for `kvm_nlist' and
1876 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1877 library with similar functions to the BSD variant, but doesn't
1878 provide these necessary functions.
1879 * collectd.conf(5): Various fixes and clarifications.
1880 * collectd: Remove a GNUism (unnamed unions), thus improving
1881 portability.
1882 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1883 This solves portability problems, especially for Solaris.
1884 * dns plugin: Fix a portability problem with NetBSD.
1885 * filecount plugin: Fix an off-by-one error. This error may cause a
1886 segmentation fault.
1887 * network plugin: Fix the handling of `type' in the network protocol.
1888 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1889 much larger buffer. This caused the `type' to be transferred much
1890 more often than necessary. In some cases, e. g. the `cpu' and
1891 `cpufreq' plugins being used at the same time, data may be corrupted
1892 in those files. Thanks to Bruno Prémont for debugging and reporting
1893 this issue.
1894 * processes plugin: Fix a possible segmentation fault when specifying
1895 invalid configuration options.
1896 * unixsock plugin: Make sure the initialization function is run only
1897 once. This resolves a file descriptor leak under systems which run
1898 the initialization more than once, such as Solaris.
1900 2008-10-16, Version 4.5.1
1901 * build system: Change `--enable-<plugin>' to abort with an error if
1902 dependencies are not met. Thanks to Bruno Prémont for the patch.
1903 Also, the poisoning of various string functions has been restricted
1904 to debug builds.
1905 * collectd: Fix a memory leak in the global value cache. With every
1906 *missing* value a couple of bytes would be leaked. Another memory
1907 leak in the configuration handling code has been fixed. Thanks to
1908 Niraj Tolia for reporting these issues.
1909 * collectd: Fix an off-by-one error in the ignorelist functionality.
1910 When using regular expressions, the last character would be missing,
1911 possibly matching differently from what one would expect.
1912 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1913 problem.
1914 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1915 Linzberger for reporting the bug.
1916 * iptables plugin: Fix an off-by-one error. If a string was just one
1917 character too long, it was truncated instead of reporting an error.
1918 * network plugin: Fix a memory leak in the configuration handling
1919 code. Thanks to Niraj Tolia for reporting this issue.
1920 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1921 * postgresql plugin: Don't reopen connection during reinitialization.
1922 This fixes a bug under Solaris and potentially other platforms.
1923 Missing calls to `PQclear' have been added, too. This fixes memory
1924 leaks. Thanks to ``Admin'' for reporting these bugs.
1925 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1926 library.
1927 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1928 problems with some `libc's. Thanks to Matthias Lay for reporting the
1929 bug.
1931 2008-09-04, Version 4.5.0
1932 * collectd: Added the ability to flush certain identifiers.
1933 * collectd: The concept of `notification meta data' has been
1934 introduced.
1935 * filecount plugin: The new filecount plugin counts the number of
1936 files in a directory and its subdirectories.
1937 * ipmi plugin: Sensor names have been changed to ensure unique names.
1938 Notifications upon added and removed sensors can now be generated.
1939 * notify_desktop plugin: This new plugin sends notifications to the
1940 X desktop using the structure defined in the `Desktop Notification
1941 Specification'.
1942 * notify_email plugin: This new plugin sends out notifications via
1943 email, using the `esmtp' library.
1944 * onewire plugin: The new experimental(!) onewire plugin reads values,
1945 such as temperatures, from sensors connected to the computer via the
1946 onewire bus.
1947 * perl plugin: Improved synchronized access to internal data structures
1948 and fixed a possible dead-lock.
1949 * perl plugin: Added the ability to flush certain identifiers and marked
1950 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1951 plugin_flush().
1952 * perl plugin: Added the ability to configure Perl plugins.
1953 * postgresql plugin: The new postgresql plugin collects statistics
1954 about or from a PostgreSQL database.
1955 * processes plugin: The `ProcessMatch' option has been added.
1956 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1957 IO load.
1958 * tcpconns plugin: This plugin has been ported to OpenBSD.
1959 * thermal plugin: The new thermal plugin collects system temperatures
1960 using Linux ACPI thermal zone data.
1962 2009-01-02, Version 4.4.5
1963 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1964 file may be in both locations, especially when the database was
1965 installed in a non-standard path. Thanks to Dusty Doris for
1966 reporting this.
1967 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1968 Solaris, in the configure script automatically.
1969 * collectd.conf(5): Various fixes and clarifications.
1970 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1971 portability problems, especially for Solaris.
1972 * dns plugin: Fix a portability problem with NetBSD.
1973 * network plugin: Fix the handling of `type' in the network protocol.
1974 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1975 much larger buffer. This caused the `type' to be transferred much
1976 more often than necessary. In some cases, e. g. the `cpu' and
1977 `cpufreq' plugins being used at the same time, data may be corrupted
1978 in those files. Thanks to Bruno Prémont for debugging and reporting
1979 this issue.
1980 * unixsock plugin: Make sure the initialization function is run only
1981 once. This resolves a file descriptor leak under systems which run
1982 the initialization more than once, such as Solaris.
1984 2008-10-16, Version 4.4.4
1985 * build system: Change `--enable-<plugin>' to abort with an error if
1986 dependencies are not met. Thanks to Bruno Prémont for the patch.
1987 Also, the poisoning of various string functions has been restricted
1988 to debug builds.
1989 * collectd: Fix a memory leak in the global value cache. With every
1990 *missing* value a couple of bytes would be leaked. Another memory
1991 leak in the configuration handling code has been fixed. Thanks to
1992 Niraj Tolia for reporting these issues.
1993 * collectd: Fix an off-by-one error in the ignorelist functionality.
1994 When using regular expressions, the last character would be missing,
1995 possibly matching differently from what one would expect.
1996 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1997 problem.
1998 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1999 Linzberger for reporting the bug.
2000 * network plugin: Fix a memory leak in the configuration handling
2001 code. Thanks to Niraj Tolia for reporting this issue.
2002 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2003 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2004 problems with some `libc's. Thanks to Matthias Lay for reporting the
2005 bug.
2007 2008-09-01, Version 4.4.3
2008 * collectd: Fix a memory leak in the threshold checking code.
2009 * memcached plugin: Fix a too short timeout and a related file
2010 descriptor leak.
2011 * memory plugin: A typo in the libstatgrab code has been fixed.
2012 * snmp plugin: Fix a possible memory leak.
2014 2008-07-15, Version 4.4.2
2015 * build system: Use pkg-config to detect the upsclient library.
2016 * collectd: Try even harder to determine the endianess of the
2017 architecture collectd is being built on.
2018 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2019 of disks.
2020 * dns plugin: Fix compilation errors with BIND versions 19991001
2021 through 19991005.
2022 * network plugin: Bugfix in the init routine: The init function
2023 cleared a buffer regardless of its contents. This could lead to lost
2024 values under Solaris.
2025 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2026 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2027 function.
2028 * wireless plugin: Work around incorrect noise and power values
2029 returned by some broken drivers.
2031 2008-06-03, Version 4.4.1
2032 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2033 to kyrone for reporting this.
2034 * collectd: Fixed min/max output in notifications generated by
2035 threshold checking.
2036 * collectd-nagios: Fix the protocol used to communicate with the
2037 daemon.
2038 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2039 initialization has errors. An issue with Perl 5.10 has been fixed.
2040 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2041 René Rebe and Siegmund Gorr for reporting this.
2043 2008-05-06, Version 4.4.0
2044 * collectd: Internal code cleanups.
2045 * collectd: Added support for a `Flush' command in the unixsock and
2046 exec plugins. This command can be used to force a plugin (or all) to
2047 flush its values to disk.
2048 * collectd: Thresholds can now be configured to apply to one data
2049 source only, making it possible to configure different thresholds
2050 for each data source.
2051 * apache, nginx plugins: Added the possibility to disable host and/or
2052 peer verification.
2053 * ascent plugin: The new ascent plugin reads and parses the statistics
2054 page of an Ascent server.
2055 * cpu plugin: Support for the statgrab library has been added.
2056 * disk plugin: The possibility to ignore certain disks or collect only
2057 specific disks has been added.

2059 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
2060 sensor values via IPMI, the intelligent platform management
2061 interface.
2062 * iptables plugin: The iptc library that is used by the iptables
2063 plugin has been added to the distribution, because it is not
2064 provided by all distributions and removed from at least one.

2073 and number of channels.
2074 * users plugin: Support for the statgrab library has been added.
2075 * vmem plugin: The new vmem plugin collects very detailed statistics
2076 about the virtual memory subsystem of Linux.

2079 * Build system: Improved detection of and linking with the statgrab
2080 library.
2081 * collectd: Portability fixes, especially to determine endianess more
2082 reliable.
2083 * Various plugins: Fix format strings.
2084 * disk plugin: A fix for giving disks under Linux 2.4 the right names
2085 again has been applied.

2098 they are in non-standard paths.
2099 * build system: Portability fixes: Automatically define "_REENTRANT"
2100 if the libc expects it.
2101 * collectd: Error and warning messages have been improved.
2102 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2103 using them.
2104 * apache plugin: Allocate new memory when reading a webpage instead of

2107 the program.
2108 * hddtemp plugin: Error and warning messages have been improved.
2109 * sensors plugin: Fix sensor collection for some chip types.
2111 2008-03-29, Version 4.3.2
2112 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2113 `Persist' threshold options.
2114 * collectd: Fix handling of missing values in the global value cache.
2115 * collectd: Improved error messages when parsing the configuration.
2116 * sensors plugin: Fix temperature collection with libsensors4.
2117 * unixsock plugin: Fix mixed input and output operation on streams.
2118 * wireless plugin: Fix reading noise value.
2120 2008-03-05, Version 4.3.1
2121 * exec plugin: Set supplementary group IDs.
2122 * network plugin:
2123 + Use `memcpy' when constructing/parsing a package to avoid
2124 alignment problems on weird architectures, such as Sparc.
2125 + Translate doubles to/from the x86 byte representation to ensure
2126 cross-platform compatibility.
2127 * ping plugin: Correct the handling of the `TTL' setting.
2128 * swap plugin: Reapply a patch for Solaris.
2129 * tcpconns plugin: Portability improvements.
2131 2008-02-18, Version 4.3.0
2132 * collectd: Notifications have been added to the daemon. Notifications
2133 are status messages that may be associated with a data instance.
2134 * collectd: Threshold checking has been added to the daemon. This
2135 means that you can configure threshold values for each data
2136 instance. If this threshold is exceeded a notification will be
2137 created.
2138 * collectd: The new `FQDNLookup' option tells the daemon to use the
2139 full qualified domain name as the hostname, not just the host part
2140 es returned by `gethostname(2)'.
2141 * collectd: Support for more than one `TypesDB' file has been added.
2142 This is useful when one such file is included in a package but one
2143 wants to add custom type definitions.
2144 * collectd: The `Include' config option has been expanded to handle
2145 entire directories and shell wildcards.
2146 * collectdmon: The new `collectdmon' binary detects when collectd
2147 terminates and automatically restarts it again.
2148 * csv plugin: The CSV plugin is now able to store counter values as a
2149 rate, using the `StoreRates' configuration option.
2150 * exec plugin: Handling of notifications has been added and the
2151 ability to pass arguments to the executed programs has been added.
2152 * hddtemp plugin: The new `TranslateDevicename' option lets you
2153 disable the translation from device names to major-minor-numbers.
2154 * logfile plugin: Handling of notifications has been added.
2155 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2156 domain name lookups in this plugin.
2157 * perl plugin: Many internal changes added support for handling multiple
2158 threads making the plugin reasonably usable inside collectd. The API has
2159 been extended to support notifications and export global variables to
2160 Perl plugins; callbacks now have to be identified by name rather than a
2161 pointer to a subroutine. The plugin is no longer experimental.
2162 * uuid plugin: The new UUID plugin sets the hostname to an unique
2163 identifier for this host. This is meant for setups where each client
2164 may migrate to another physical host, possibly going through one or
2165 more name changes in the process. Thanks to Richard Jones from
2166 Red Hat's Emerging Technology group for this plugin.
2167 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2168 CPU, disk and network statistics about guest systems on the same
2169 physical server. Thanks to Richard Jones from Red Hat's Emerging
2170 Technology group for this plugin.
2172 2008-04-22, Version 4.2.7
2173 * build system: Improved detection of several libraries, especially if
2174 they are in non-standard paths.

2178 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2179 using them.
2180 * apache plugin: Allocate new memory when reading a webpage instead of
2181 using a buffer of static size.
2182 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2183 the program.
2184 * hddtemp plugin: Error and warning messages have been improved.
2185 * sensors plugin: Fix sensor collection for some chip types.
2187 2008-03-29, Version 4.2.6
2188 * collectd: Improved error messages when parsing the configuration.
2189 * sensors plugin: Fix temperature collection with libsensors4.
2190 * unixsock plugin: Fix mixed input and output operation on streams.
2191 * wireless plugin: Fix reading noise value.
2193 2008-03-04, Version 4.2.5
2194 * apache plugin: Improved initialization and error messages.
2195 * exec plugin: Set supplementary group IDs.
2196 * network plugin:
2197 + Create separate threads for reading from the socket and parsing
2198 and dispatching incoming packets. Versions prior to this may have
2199 problems in high-load situations, where the socket receive buffers
2200 overflows, resulting in gaps in the data.
2201 + Use `memcpy' when constructing/parsing a package to avoid
2202 alignment problems on weird architectures, such as Sparc.
2203 + Translate doubles to/from the x86 byte representation to ensure
2204 cross-platform compatibility.
2205 * ping plugin: Correct the handling of the `TTL' setting.
2206 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2207 * swap plugin: Reapply a patch for Solaris.
2208 * tcpconns plugin: Portability improvements.
2210 2008-01-21, Version 4.2.4
2211 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2212 the permission on the socket as documented in the manpage. Thanks to
2213 Evgeny Chukreev for fixing this issue.
2214 * collectd: The documentation has been improved.
2216 2007-12-28, Version 4.2.3
2217 * sensors plugin: Updated the plugin to build and work with version 3
2218 of the libsensors library.
2220 2007-12-15, Version 4.2.2
2221 * nginx plugin: Incorrect comparison of strings lead to a segfault
2222 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2223 this.
2224 * logfile plugin: The config option `Timestamp' was handled
2225 incorrectly and basically always active. Thanks to Luke Heberling
2226 for fixing this.
2228 2007-11-08, Version 4.2.1
2229 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2230 enabled on the host.
2231 * snmp plugin: Fix a memory leak.
2233 2007-10-27, Version 4.2.0
2234 * collectd: The new config option `Include' lets you include other
2235 configfiles and thus split up your config into smaller parts. This
2236 may be especially interesting for the snmp plugin to keep the data
2237 definitions separate from the host definitions.
2238 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2239 (number of connections, octets and packets for each service and
2240 destination). Thanks to Sebastian Harl for this plugin.
2241 * memcached plugin: The new `memcached' plugin connects to a memcached
2242 daemon process and collects statistics of this distributed caching
2243 system. Thanks to Antony Dovgal for contributing this plugin.
2244 * nginx plugin: The new `nginx' plugin reads the status page of an
2245 nginx daemon and saves the handled connections and requests.
2246 * perl plugin: Many changes, including the added `EnableDebugger'
2247 config option which lets you debug your Perl plugins more easily.
2248 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2249 be more thread-safe otherwise by locking calls to the library.
2250 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2251 correct the values returned by SNMP-agents. If a <data> block is
2252 defined as `table' the instance is now optional. The sequence number
2253 is used as the type-instance in this case. The new `InstancePrefix'
2254 option allows to add arbitrary prefixes to the type-instance.
2255 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2256 certain TCP connections and what state they're in. This can be used
2257 to see how many connections your FTP server has to handle or how
2258 many outgoing connections your mailserver has open.
2260 2008-01-11, Version 4.1.6
2261 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2262 the permission on the socket as documented in the manpage. Thanks to
2263 Evgeny Chukreev for fixing this issue.
2264 * collectd: The documentation has been improved.
2266 2007-12-27, Version 4.1.5
2267 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
2268 memory situations.
2269 * sensors plugin: Updated the plugin to build and work with version 3
2270 of the libsensors library.
2272 2007-11-08, Version 4.1.4
2273 * Build system: Improve detection of the rrd library, especially if
2274 it's in a non-standard location.
2275 * Build system: A bug when parsing the argument for
2276 `--with-libnetsnmp' has been fixed.
2277 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2278 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2279 a deadlock or delay when shutting down the daemon.
2280 * snmp plugin: Fix a memory leak.
2282 2007-10-24, Version 4.1.3
2283 * collectd: A build issue under Solaris has been resolved by renaming
2284 data types.
2285 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2286 be more thread-safe otherwise by locking calls to the library.
2288 2007-09-28, Version 4.1.2
2289 * apcups plugin: Fix reporting of the `load percent' data.
2290 * wireless plugin: Correct the handling of cards returning signal and
2291 noise quality as percentage.
2292 * perl plugin: Fix a possible buffer overflow in get_module_name().
2293 * build system: Further improve the detection of libraries.
2294 * netlink plugin: Build issues under some older versions of the Linux
2295 includes (i. e. Debian Sarge) have been fixed.
2296 * snmp plugin: Fix a potential segfault when a host times out. Add
2297 support for the `timeticks' type.
2299 2007-09-12, Version 4.1.1
2300 * Build system: The detection of `libnetlink' has been improved.
2301 * collectd: The documentation has been fixed in numerous places.
2302 * exec plugin: Setting the group under which to run a program has been
2303 fixed.
2304 * collectd: The `sstrerror' function was improved to work correctly
2305 with the broken GNU version of `strerror_r'.
2306 * collectd: Write an error message to STDERR when loading of a plugin
2307 fails.
2308 * apcups plugin: Fix the `types' used to submit the values: They still
2309 has an `apcups_' prefix which doesn't work anymore.
2310 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2311 whatever the client thinks is `now'..
2313 2007-09-01, Version 4.1.0
2314 * Build system: The build system has been changed to automatically
2315 disable all plugins, which are missing dependencies. The dependency
2316 checking has been removed from the plugins themselves to remove
2317 redundancy.
2318 * Flexible interval: The interval of collected data is now sent along
2319 with the data itself over the network, so that the interval-settings
2320 of server and clients no longer needs to match.
2321 * netlink plugin: The new `netlink' plugin connects to the Linux
2322 kernel using a netlink socket and uses it to query information about
2323 interfaces, qdiscs and classes.
2324 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2325 to not block data collection.
2326 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2327 network devices, such as switches, routers, thermometers, rack
2328 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2329 plugin.
2330 * unixsock plugin: Added the `LISTVAL' command.
2331 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
2332 of music played with xmms.
2334 2007-09-28, Version 4.0.9
2335 * apcups plugin: Fix reporting of the `load percent' data.
2336 * wireless plugin: Correct the handling of cards returning signal and
2337 noise quality as percentage.
2338 * perl plugin: Fix a possible buffer overflow in get_module_name().
2340 2007-09-12, Version 4.0.8
2341 * collectd: The `sstrerror' function was improved to work correctly
2342 with the broken GNU version of `strerror_r'.
2343 * collectd: Write an error message to STDERR when loading of a plugin
2344 fails.
2345 * apcups plugin: Fix the `types' used to submit the values: They still
2346 has an `apcups_' prefix which doesn't work anymore.
2347 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2348 whatever the client thinks is `now'..
2350 2007-08-26, Version 4.0.7
2351 * documentation: Some typos have been fixed and some information has
2352 been improved.
2353 * build system: Many fixes for detecting libraries in unusual places,
2354 such as on RedHat systems. The affected libraries are `libcurl',
2355 `libmysql', and `libupsclient'.
2356 * network plugin: Allow the `Port' option to be specified as a number
2357 (i. e. without quotes).
2358 * nut plugin: A fix allows linking the nut plugin against
2359 libupsclient, version >= 2.2.0.
2360 * processes plugin: Fix a potential segmentation fault.
2362 2007-07-30, Version 4.0.6
2363 * sensors plugin: Fix the ignorelist functionality: Only the `type
2364 instance' was used to match against the list, but the documentation
2365 told otherwise. This release fixes the code, so it complies with the
2366 documentation.
2367 * syslog plugin: Call `openlog' right when the plugin is loaded, so
2368 configuration messages will end up in the logging facility.
2369 * conrtib/fedora: The contributed specfile for Fedora has been
2370 updated.
2372 2007-07-05, Version 4.0.5
2373 * Portability: More fixes for OpenBSD have been included.
2375 2007-06-24, Version 4.0.4
2376 * cpu plugin: Fixed the Solaris code.
2377 * dns plugin: Fixed a build issue for OpenBSD.
2378 * interface plugin: Fixed the Solaris code.
2379 * load plugin: Fixed the alternative `/proc' Linux code.
2380 * memory plugin: Fixed the Solaris code.
2381 * oconfig: Don't require `-lfl' anymore.
2383 2007-06-19, Version 4.0.3
2384 * cpu plugin: Fix the Darwin / Mac OS X code.
2385 * ping plugin: Use the return value of `getpid', not its address.
2386 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
2387 initialized correctly.
2388 * configure: Added `--with-nan-emulation' to aid cross compilation.
2390 2007-06-12, Version 4.0.2
2391 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
2392 they're given in numerically form.
2394 2007-06-07, Version 4.0.1
2395 * iptables plugin: A bug in the configuration routine has been fixed.
2396 Setting a comment in the configfile will no longer cause a
2397 segmentation fault.
2399 2007-06-03, Version 4.0.0
2400 * collectd: The plugin-infrastructure has been changed to allow for
2401 more types of plugins, namely `write' and `log' plugins.
2402 * collectd: The read-function has been changed to read many plugins in
2403 parallel, using threads. Thus, plugins generally need to use
2404 thread-safe functions from now on.
2405 * collectd: The '-t' command line options allows to perform syntax tests
2406 of the configuration file and exit immediately.
2407 * csv plugin: The new `csv' plugin handles output to `comma separated
2408 values'-files.
2409 * rrdtool plugin: The new `rrdtool' plugin handles output to
2410 RRD-files. Data can be cached to combine multiple updates into one
2411 write to increase IO-performance.
2412 * network plugin: The new `network' plugin handles IO via the network.
2413 It implements a different, much more extensible protocol which can
2414 combine many values in one packet, decreasing the number of UDP-
2415 packets being sent. It can read from and send to the network and
2416 with the appropriate configuration even forward packets to other
2417 networks.
2418 * unixsock plugin: The new `unixsock' plugin provides an interface to
2419 communicate with the daemon while it is running. Right now the
2420 commands `GETVAL' and `PUTVAL' are implemented, but more are to
2421 come.
2422 * perl plugin: The new `perl' plugin allows you to write extensions
2423 for collectd in the scripting-language Perl.
2424 * logfile plugin: The new `logfile' plugin writes logmessages to files
2425 or STDOUT or STDERR.
2426 * syslog plugin: The new `syslog' plugin sends logmessages to the
2427 system's syslog daemon.
2428 * entropy plugin: The new `entropy' plugin collects the amount of
2429 entropy currently being available to the system.
2430 * exec plugin: The new `exec' plugin forks child processes and reads
2431 back values provided by the forked processes.
2432 * iptables plugin: The new `iptables' plugin reads counters from
2433 iptables rules. Thanks to Sjoerd van der Berg for contributing this
2434 plugin.
2435 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
2436 to Peter Holik for contributing this plugin.
2437 * nut plugin: The new `nut' plugin connects the upsd of the `network
2438 ups tools' and reads information about the connected UPS.
2439 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2440 connections) field was added by Florent Monbillard.
2441 * collectd-nagios: The new `collectd-nagios' binary queries values
2442 from collectd, parses them and exits according to Nagios-standards.
2443 * manpages: The manpages have been improved a lot.
2445 2007-09-28, Version 3.11.7
2446 * wireless plugin: Correct the handling of cards returning signal and
2447 noise quality as percentage.
2449 2007-08-31, Version 3.11.6
2450 * processes plugin: Fix a potential segmentation fault.
2452 2007-05-29, Version 3.11.5
2453 * configure: Added `AC_SYS_LARGEFILE' for LFS.
2454 * ntpd plugin: Fix a potential buffer overflow.
2455 * processes plugin: Fix a bug when run under Linux 2.4. All processes
2456 were accounted as `zombies'.
2458 2007-04-10, Version 3.11.4
2459 * dns plugin: Change the order of includes to make the plugin compile
2460 under FreeBSD.
2462 2007-03-30, Version 3.11.3
2463 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
2464 of the unused `COLLECT_KSTAT'.
2466 2007-02-11, Version 3.11.2
2467 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
2468 NULL-pointer may have been passed to `printf' which causes a
2469 segfault with some libcs.
2471 2007-02-10, Version 3.11.1
2472 * df plugin: Some wrong defines have been fixed so the plugin works
2473 under Solaris again.
2474 * dns plugin: The usage of a struct has been fixed to work with
2475 non-GNU libcs.
2476 * processes plugin: Some missing defines have been added so the plugin
2477 compiles cleanly under FreeBSD and presumably other UNIXes.
2479 2006-12-22, Version 3.11.0
2480 * collectd: The new command line option `-P' makes it easier for
2481 distributors to change the location of PID-files.
2482 * collectd: The daemon shuts down faster now which makes it easier to
2483 write init.d-scripts for it.
2484 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
2485 caused problems every now and then.
2486 * df plugin: New config options allow to ignore certain mountpoints,
2487 filesystem types or devices.
2488 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
2489 and interprets it. It collects traffic as well as qtype, opcode and
2490 rcode counts.
2491 * email plugin: Sebastian Harl has contributed this plugin which
2492 counts received mails in categories (e. g. ham, spam, virus), spam
2493 score (as given by SpamAssassin) and check types.
2494 * mbmon plugin: Flavio Stanchina has contributed this plugin which
2495 uses `mbmon' to gather information from sensors on the motherboard.
2496 * processes plugin: Collect detailed statistics for configured
2497 processes, that's process and thread count, CPU usage, resident
2498 segment size and pagefaults.
2499 * multimeter plugin: Peter Holik contributed a new plugin which
2500 queries multimeters.
2501 * sensors plugin: Lubos Stanek has put much effort into improving this
2502 plugin, including `extended naming', collection of voltage values
2503 and the possibility to ignore certain values.
2505 2006-12-21, Version 3.10.4
2506 * Max Kellermann has identified a bug in the server routine: When
2507 opening a socket fails the daemon will (re)try opening the socket in
2508 an endless loop, ultimately leading to a `EMFILE' error.
2510 2006-11-04, Version 3.10.3
2511 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
2512 ntpd's reply was sent in more than one packet, the buffer size was
2513 calculated incorrectly, resulting in the reading of uninitialized or
2514 freed memory.
2516 2006-11-01, Version 3.10.2
2517 * The sample config file has been improved.
2518 * Errors in the manpages have been corrected.
2519 * The ping-plugin now adds hosts during initialization, not during
2520 startup. This speeds up startup when no network connectivity is
2521 available. Also, the hosts are being added later when the network is
2522 available.
2523 * Improved BSD-support for the df-plugin.
2524 * Fixed syntax errors in the swap-plugin for Mac OS X.
2525 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2526 plugin.
2527 * Don't disable the mysql-plugin if connecting to the database fails
2528 during initialization. Instead, try again in increasing intervals.
2530 2006-07-19, Version 3.10.1
2531 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2532 the apcups cannot be reached, unconnected sockets will pile up and
2533 eventually lead to `Too many open files' errors.
2535 2006-07-09, Version 3.10.0
2536 * The `disk' plugin has been ported to Darwin.
2537 * The `battery' plugin should work on many Apple computers now.
2538 * The `traffic' plugin can now ignore certain interfaces. Also,
2539 statistics for sent/received packets and errors have been added.
2540 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2541 to Anthony Gialluca for contributing this plugin and providing me
2542 with a test environment :)
2543 * A plugin for monitoring an NTP instance and the local clock drift
2544 has been added.
2546 2006-06-25, Version 3.9.4
2547 * The Solaris code in the `swap' plugin has been changed to reflect
2548 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2549 working this out.
2550 * The debugging system has been fixed to work with the Sun libc.
2551 * When built without librrd the variable `operating_mode' could be
2552 uninitialized. Thanks to David Elliot for reporting the bug.
2554 2006-06-01, Version 3.9.3
2555 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2556 operating systems also profit from the changes, but I wasn't able to
2557 check that.
2558 * Changed the build system to find the netinet-includes under FreeBSD
2559 and therefore successfully build the `liboping' library there.
2561 2006-05-09, Version 3.9.2
2562 * Applied a patch to the `liboping' library. Due to a bug in the
2563 sequence checking the `ping' plugin stopped working after
2564 approximately 7.6 days.
2566 2006-05-09, Version 3.8.5
2567 * Applied a patch to the `liboping' library. Due to a bug in the
2568 sequence checking the `ping' plugin stopped working after
2569 approximately 7.6 days.
2571 2006-04-21, Version 3.9.1
2572 * Build issues with Solaris and possible other architectures have been
2573 resolved.
2574 * Problems when building the `apache'-plugin without `libcurl' have
2575 been resolved.
2576 * A bug in the `ping' plugin has been fixed. Sorry folks.
2578 2006-04-02, Version 3.9.0
2579 * A plugin to monitor the Apache webserver has been added.
2580 <http://httpd.apache.org/>
2581 * A plugin to collect statistics about virtual servers using VServer.
2582 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2583 this plugin :)
2584 * A plugin for wireless LAN cards has been added. It monitors signal
2585 strength, link quality and noise ratio..
2586 * A plugin for Apple hardware sensors has been added.
2587 * An option to compile collectd with different `step' and `heartbeat'
2588 settings has been added. The size of RRAs is no longer static but
2589 calculated based on the settings for `step' and `width'.
2590 * The `ping' plugin can now be configured to use a certain TTL.
2591 * A plugin to monitor the hardware sensors of Apple computers has been
2592 added.
2593 * The plugins `cpu', `memory', `processes' and `traffic' have been
2594 ported to Mach/Darwin (Mac OS X).
2595 * The `log mode' has been contributed by Christophe Kalt. It writes
2596 the data into text files rather than RRD files.
2598 2006-04-09, Version 3.8.4
2599 * Applied patch by Vincent Stehlé which improves the disk-name
2600 resolution in the `hddtemp' plugin for Linux systems.
2602 2006-04-02, Version 3.8.3
2603 * Applied a patch by James Byers: The MySQL plugin was not working
2604 with MySQL 5.0.2 or later.
2606 2006-03-14, Version 3.8.2
2607 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2608 the GNU libc, because it points to `/etc/fstab' rather than
2609 `/etc/mtab'.
2611 2006-03-13, Version 3.8.1
2612 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2613 * Fixes in the debian `postinst' and `init.d' scripts.
2615 2006-03-09, Version 3.8.0
2616 * The `ping' plugin no longer uses `libping' but a self written
2617 library named `liboping'. With this library it's possible to ping
2618 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2620 2006-02-18, Version 3.7.2
2621 * A simple bug in the `battery' plugin has been fixed. It should now
2622 work with ACPI based batteries as well. Thanks to Sebastian for
2623 fixing this.
2624 * Fixing a bug that prevented collectd to be built without librrd.
2625 Thanks to Werner Heuser for reporting it.
2627 2006-02-04, Version 3.7.1
2628 * The new network code has been improved to build with older versions
2629 of glibc.
2630 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2631 to Tommie Gannert for this patch.
2633 2006-01-30, Version 3.7.0
2634 * The `battery' plugin has been added. It collects information about
2635 laptop batteries..
2636 * The MySQL plugin has been improved: It now writes two more RRD
2637 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2638 * The `cpufreq' plugin now reads another file since the file it did
2639 read so far causes much overhead in the kernel. Also, you need root
2640 to read the old file, but not to read the new one.
2641 * The `hddtemp' plugin can now be configured to connect to another
2642 address and/or port than localhost.
2643 * The `df' plugin now prefers `statvfs' over `statfs'.
2644 * The network code has been rewritten. collectd now supports unicast
2645 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2646 be set in the configfile.
2648 2006-01-24, Version 3.6.2
2649 * Due to a bug in the configfile handling collectd wouldn't start in
2650 client mode. This released fixes this.
2652 2006-01-20, Version 3.6.1
2653 * Due to a bug in `configure.in' all modules and the binary were
2654 linked against `libmysqlclient'. This issue is solved by this
2655 release.
2657 2006-01-17, Version 3.6.0
2658 * A config file has been added. This allows for loading only specific
2659 plugins.
2660 * A `df' plugin has been added.
2661 * A `mysql' plugin has been added.
2662 * The `ping' plugin doesn't entirely give up hope when a socket error
2663 occurred, but will back of and increase the intervals between tries.
2665 2006-01-21, Version 3.5.2
2666 * Fixed yet another bug in the signal handling.. Stupid typo..
2667 * Improved the ping plugin to not give up on socket errors (backport
2668 from 3.6.0).
2670 2005-12-18, Version 3.5.1
2671 * The PID-file is now deleted correctly when shutting down the daemon.
2672 * SIGINT and SIGTERM are now handled correctly.
2674 2005-12-16, Version 3.5.0 (Revision 326)
2675 * A bug in the `load' module under Solaris has been fixed.
2676 * The `users' module has been contributed by Sebastian Harl. It counts
2677 currently logged in users.
2678 * The CPU module now works under FreeBSD without the use of
2679 `libstatgrab', however SMP support is missing.
2680 * The default directories for the RRD files and the PID file now
2681 depend on the compile time setting of `localstatedir'.
2683 2005-11-15, Version 3.4.0 (Revision 236)
2684 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2685 from gentoo's bugzilla for writing the patch.
2686 * The build dependency for librrd has been removed. Binaries built
2687 without librrd are client-only and will multicast their value as
2688 with the `-c' argument.
2689 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2690 * The newly introduced `-f' switch prevents daemon initialization
2691 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2692 Barcellos for this patch.
2694 2005-11-04, Version 3.3.0 (Revision 216)
2695 * New modules have been added:
2696 - `serial', for monitoring traffic on the serial interfaces
2697 - `nfs', for graphing NFS procedure calls
2698 - `tape', traffic from/to tape devices
2699 * The memory.rrd now accepts more than 4Gig of memory.
2701 2005-10-26, Version 3.2.0 (Revision 200)
2702 * Support for graphing the processes has been added (thanks to Lyonel
2703 Vincent)
2704 * If reading from hddtemp fails collectd will increase the time
2705 between polls up to one day.
2706 * The init.d files have been improved.
2707 * Problems with the spec file have been fixed.
2709 2005-10-16, Version 3.1.0 (Revision 194)
2710 * Added the `setsid' syscall to the startup code.
2711 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2713 2005-09-30, Version 3.0.0 (Revision 184)
2714 * The ability to send/receive data to/from the network (think
2715 multicast) has been added.
2716 * Modules have been split up into shared libraries can be loaded at
2717 runtime. The biggest advantage is that the core program doesn't need
2718 to be linked against an external library.
2719 * A patch by George Kargiotakis has been applied: It fixes the sensors
2720 behaviour then more than one sensor is being queried.
2722 2005-09-16, Version 2.1.0 (Revision 172)
2723 * A module for swap statistics has been added.
2725 2005-09-09, Version 2.0.0 (Revision 135)
2726 * Filenames can no longer be configured at program startup. The only
2727 options as of this version are the directory and ping hosts.
2728 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2729 Soft-IRQ statistics are added to `System'.
2730 * Diskstats now collect read and write bytes, not sectors.
2731 * Ping statistics can now be collected for more than one host. There
2732 is no default any more: If no host is given no host will be pinged.
2733 * A self-written patch for libping has been applied so it builds
2734 cleanly.
2736 2005-09-01, Version 1.8.1 (Revision 123)
2737 * Much improved configure-script: libraries and features may now be
2738 disabled.
2739 * More detailed warnings/error messages when RRD update fails.
2741 2005-08-29, Version 1.8.0:
2742 * Support for collecting disk statistics under Solaris.
2744 2005-08-25, Version 1.7.0:
2745 * Support for libstatgrab[1] for load, memory usage and network
2746 traffic. CPU- and disk-usage are not (yet) supported, since
2747 libstatgrab returns insufficient information. I will contact the
2748 authors.
2749 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2750 aren't necessarily counted linear which is now handled correctly.
2751 [1]: http://www.i-scream.org/libstatgrab/
2753 2005-08-21, Version 1.6.0:
2754 * Basic support for Solaris: System load and cpu-usage can be
2755 collected under Solaris, too. Other stats will follow later.
2756 * Many fixes in the autoconf-script
2757 * Collection/Museum scripts have been added under contrib/museum
2758 * collectd may now be started in unprivileged mode, though ping
2759 statistics will not work.
2761 2005-07-17, Version 1.5.1:
2762 * Diskstats-RRDs now use major/minor for naming. Some systems have
2763 weird strings as disk-names..
2765 2005-07-17, Version 1.5:
2766 * A new module, diskstats, has been added. It collects information
2767 about the disks and partitions.
2769 2005-07-11, Version 1.4.2:
2770 * The meminfo module has been changed to work with more platforms
2771 and/or kernel versions.
2773 2005-07-10, Version 1.4.1: Correct traffic stats
2774 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2775 forgot to correct when I changed that module.
2777 2005-07-09, Version 1.4: More traffic stats
2778 * Traffic is now collected for all interfaces that can be found
2779 * Temperature-statistics are read from lm-sensors if available
2781 2005-07-08, Version 1.3: CPU stats
2782 * Collecting CPU statistics now
2784 2005-07-12, Version 1.2: Using syslog
2785 * collectd is now using the syslog facility to report errors, warnings
2786 and the like..
2787 * The default directory is now /var/db/collectd
2789 2005-07-10, Version 1.1: Minor changes
2790 * Nothing really useful to say ;)
2792 2005-07-09, Version 1.0: Initial Version
2793 * The following modules are provided:
2794 * Load average
2795 * Ping time
2796 * Traffic
2797 * Memory info
