2009-02-16, Version 4.6.0 * collectd: Added the `filter chain' infrastructure, which allows the user to use `matches' and `targets' to control value processing. * collectd: The new `-T' command line argument allows more in-depth testing of a configuration. Thanks to Doug MacEachern for the patch. * collectd-nagios: The Nagios integration command has been updated to use libcollectdclient. The `percentage' aggregation function has been added. Thanks to Fabian Linzberger for the patch. * libcollectdclient: A library which abstracts communication with the unixsock plugin for clients has been added. * regex match: Match values by their identifies using regular expressions. * timediff match: Match for values with an invalid timestamp. * value match: Select values by their data sources' values. * notification target: Create and dispatch a notification. * replace target: Replace parts of an identifier using regular expressions. * set target: Set (overwrite) entire parts of an identifier. * bind plugin: This new plugin uses the new HTTP/XML interface to BIND statistics, allowing very detailed name server statistics. Thanks to Bruno Prémont for this plugin. * cpu plugin: Report `interrupt' separately when using sysctlbyname(3) (used under *BSD). Support for sysctl(3), for example for native OpenBSD support, has been added. Thanks to Simon Kuhnle for the patch. * csv plugin: Make it possible to write values to STDOUT instead of files. This is meant for testing purposes mostly. The output written to STDOUT is compatible with the exec plugin. Thanks to Doug MacEachern for the patch. * curl plugin: This new plugin can be used to read web pages and parse them using the same mechanism that's used in the tail plugin. * dbi plugin: This new plugin allows you to connect to a variety of relational databases and use SQL to gather custom statistics from it. It is similar to the already existing PostgreSQL plugin but uses libdbi to communicate with the database(s). * interface plugin: Use the ignorelist framework when selecting / ignoring interfaces. This allows one to use regular expressions to select interfaces, too. * ipmi plugin: Handle temporary IPMI error conditions more gracefully. Thanks to Bruno Prémont for this patch. * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern for the patch. * mysql plugin: Allow connecting to a database via the UNIX domain socket, too. Thanks to Mirko Buffoni for the patch. * network plugin: Further performance improvements for the receive code. This hopefully will help very large setups. * openvpn plugin: This new plugin collects statistics provided by the OpenVPN daemon. Thanks to Doug MacEachern for the patch. * oracle plugin: This new plugin allows you to connect to an Oracle database and use SQL to gather custom statistics from it. It is similar to the already existing PostgreSQL plugin. * perl plugin: Compatibility fixes for broken versions of Perl 5.10 have been added. * perl plugin: Export the newly added plugin_write() to Perl plugins. * perl plugin: Added support for `notification meta data'. * perl plugin: Added support for the `filter chain' infrastructure by allowing plugins to register `matches' and `targets'. * postgresql plugin: The preferred configuration syntax has been updated to be in line with the syntax used by the new dbi and oracle plugins. The compatibility code for the old syntax is present. Support for the new `Result' blocks and the interval parameter has been added. * processes plugin: Stacksize and virtual memory usage statistics have been added. Portability fixes. * rrdcached plugin: This new plugin uses the (still in development) RRD accelerator daemon, rrdcached. This daemon works very similar to the original rrdtool plugin of collectd, but adds some more nice features. * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been added. 2009-01-02, Version 4.5.2 * build system: Check for `mysql.h' and `mysql/mysql.h', since the file may be in both locations, especially when the database was installed in a non-standard path. Thanks to Dusty Doris for reporting this. * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by Solaris, in the configure script automatically. * build system, tcpconns plugin: Check for `kvm_nlist' and `kvm_openfiles' before enabling the plugin: Solaris provides a KVM library with similar functions to the BSD variant, but doesn't provide these necessary functions. * collectd.conf(5): Various fixes and clarifications. * collectd: Remove a GNUism (unnamed unions), thus improving portability. * collectd, apcups plugin: Include "collectd.h" before . This solves portability problems, especially for Solaris. * dns plugin: Fix a portability problem with NetBSD. * filecount plugin: Fix an off-by-one error. This error may cause a segmentation fault. * network plugin: Fix the handling of `type' in the network protocol. Due to a programming mistake, only 4 or 8 bytes would be copied to a much larger buffer. This caused the `type' to be transferred much more often than necessary. In some cases, e. g. the `cpu' and `cpufreq' plugins being used at the same time, data may be corrupted in those files. Thanks to Bruno Prémont for debugging and reporting this issue. * processes plugin: Fix a possible segmentation fault when specifying invalid configuration options. * unixsock plugin: Make sure the initialization function is run only once. This resolves a file descriptor leak under systems which run the initialization more than once, such as Solaris. 2008-10-16, Version 4.5.1 * build system: Change `--enable-' to abort with an error if dependencies are not met. Thanks to Bruno Prémont for the patch. Also, the poisoning of various string functions has been restricted to debug builds. * collectd: Fix a memory leak in the global value cache. With every *missing* value a couple of bytes would be leaked. Another memory leak in the configuration handling code has been fixed. Thanks to Niraj Tolia for reporting these issues. * collectd: Fix an off-by-one error in the ignorelist functionality. When using regular expressions, the last character would be missing, possibly matching differently from what one would expect. * collectdmon: Don't block SIGCHLD. This fixes a potential portability problem. * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian Linzberger for reporting the bug. * iptables plugin: Fix an off-by-one error. If a string was just one character too long, it was truncated instead of reporting an error. * network plugin: Fix a memory leak in the configuration handling code. Thanks to Niraj Tolia for reporting this issue. * perl plugin: Log an error message if bootstrapping `Collectd' fails. * postgresql plugin: Don't reopen connection during reinitialization. This fixes a bug under Solaris and potentially other platforms. Missing calls to `PQclear' have been added, too. This fixes memory leaks. Thanks to ``Admin'' for reporting these bugs. * snmp plugin: Don't expect null-terminated strings from the Net-SNMP library. * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes problems with some `libc's. Thanks to Matthias Lay for reporting the bug. 2008-09-04, Version 4.5.0 * collectd: Added the ability to flush certain identifiers. * collectd: The concept of `notification meta data' has been introduced. * filecount plugin: The new filecount plugin counts the number of files in a directory and its subdirectories. * ipmi plugin: Sensor names have been changed to ensure unique names. Notifications upon added and removed sensors can now be generated. * notify_desktop plugin: This new plugin sends notifications to the X desktop using the structure defined in the `Desktop Notification Specification'. * notify_email plugin: This new plugin sends out notifications via email, using the `esmtp' library. * onewire plugin: The new experimental(!) onewire plugin reads values, such as temperatures, from sensors connected to the computer via the onewire bus. * perl plugin: Improved synchronized access to internal data structures and fixed a possible dead-lock. * perl plugin: Added the ability to flush certain identifiers and marked plugin_flush_all() and plugin_flush_one() as deprecated in favor of plugin_flush(). * perl plugin: Added the ability to configure Perl plugins. * postgresql plugin: The new postgresql plugin collects statistics about or from a PostgreSQL database. * processes plugin: The `ProcessMatch' option has been added. * rrdtool plugin: Implement throttling of the `update queue' to lessen IO load. * tcpconns plugin: This plugin has been ported to OpenBSD. * thermal plugin: The new thermal plugin collects system temperatures using Linux ACPI thermal zone data. 2009-01-02, Version 4.4.5 * build system: Check for `mysql.h' and `mysql/mysql.h', since the file may be in both locations, especially when the database was installed in a non-standard path. Thanks to Dusty Doris for reporting this. * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by Solaris, in the configure script automatically. * collectd.conf(5): Various fixes and clarifications. * apcups plugin: Include "collectd.h" before . This solves portability problems, especially for Solaris. * dns plugin: Fix a portability problem with NetBSD. * network plugin: Fix the handling of `type' in the network protocol. Due to a programming mistake, only 4 or 8 bytes would be copied to a much larger buffer. This caused the `type' to be transferred much more often than necessary. In some cases, e. g. the `cpu' and `cpufreq' plugins being used at the same time, data may be corrupted in those files. Thanks to Bruno Prémont for debugging and reporting this issue. * unixsock plugin: Make sure the initialization function is run only once. This resolves a file descriptor leak under systems which run the initialization more than once, such as Solaris. 2008-10-16, Version 4.4.4 * build system: Change `--enable-' to abort with an error if dependencies are not met. Thanks to Bruno Prémont for the patch. Also, the poisoning of various string functions has been restricted to debug builds. * collectd: Fix a memory leak in the global value cache.

This could lead to lost values under Solaris. * nginx plugin: Remove usage of the thread-unsafe `strtok' function. * vserver plugin: Remove usage of the thread-unsafe `readdir' function. * wireless plugin: Work around incorrect noise and power values returned by some broken drivers. 2008-06-03, Version 4.4.1 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks to kyrone for reporting this. * collectd: Fixed min/max output in notifications generated by threshold checking. * collectd-nagios: Fix the protocol used to communicate with the daemon. * perl plugin: Fail noisily, but don't shutdown the daemon, if initialization has errors. An issue with Perl 5.10 has been fixed. * teamspeak2 plugin: Fixed an out of bound array access. Thanks to René Rebe and Siegmund Gorr for reporting this. 2008-05-06, Version 4.4.0 * collectd: Internal code cleanups. * collectd: Added support for a `Flush' command in the unixsock and exec plugins. This command can be used to force a plugin (or all) to flush its values to disk. * collectd: Thresholds can now be configured to apply to one data source only, making it possible to configure different thresholds for each data source. * apache, nginx plugins: Added the possibility to disable host and/or peer verification. * ascent plugin: The new ascent plugin reads and parses the statistics page of an Ascent server. * cpu plugin: Support for the statgrab library has been added. * disk plugin: The possibility to ignore certain disks or collect only specific disks has been added. * disk plugin: Support for the statgrab library has been added. * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read sensor values via IPMI, the intelligent platform management interface. * iptables plugin: The iptc library that is used by the iptables plugin has been added to the distribution, because it is not provided by all distributions and removed from at least one. * powerdns plugin: The new powerdns plugin reads statistics from an authoritative or a recursing PowerDNS name server. * rrdtool plugin: The size of the files generated with the default configuration has been decreased. * tail plugin: The new tail plugin can be used to gather statistics by continuously reading from log files. * teamspeak2 plugin: The new teamspeak2 plugin connects to a TeamSpeak2 server and collects statistics about the number of users and number of channels. * users plugin: Support for the statgrab library has been added. * vmem plugin: The new vmem plugin collects very detailed statistics about the virtual memory subsystem of Linux. 2008-08-30, Version 4.3.4 * Build system: Improved detection of and linking with the statgrab library. * collectd: Portability fixes, especially to determine endianess more reliable. * Various plugins: Fix format strings. * disk plugin: A fix for giving disks under Linux 2.4 the right names again has been applied. * memcached plugin: Fix a too short timeout and a related file descriptor leak. * memory plugin: A typo in the libstatgrab code has been fixed. * network plugin: A fix in the initialization function solves problems under Solaris. * nginx plugin: A thread-unsafe function has been replaced. * vserver plugin: A thread-unsafe function has been replaced. * wireless plugin: A work-around for broken wireless drivers has been added. 2008-04-22, Version 4.3.3 * build system: Improved detection of several libraries, especially if they are in non-standard paths. * build system: Portability fixes: Automatically define "_REENTRANT" if the libc expects it. * collectd: Error and warning messages have been improved. * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before using them. * apache plugin: Allocate new memory when reading a webpage instead of using a buffer of static size. * exec plugin: Close (almost) all filedescriptors before exec(2)ing the program. * hddtemp plugin: Error and warning messages have been improved. * sensors plugin: Fix sensor collection for some chip types. 2008-03-29, Version 4.3.2 * collectd: Fix configuration of the `FailureMax', `WarningMax', and `Persist' threshold options. * collectd: Fix handling of missing values in the global value cache. * collectd: Improved error messages when parsing the configuration. * sensors plugin: Fix temperature collection with libsensors4. * unixsock plugin: Fix mixed input and output operation on streams. * wireless plugin: Fix reading noise value. 2008-03-05, Version 4.3.1 * exec plugin: Set supplementary group IDs. * network plugin: + Use `memcpy' when constructing/parsing a package to avoid alignment problems on weird architectures, such as Sparc. + Translate doubles to/from the x86 byte representation to ensure cross-platform compatibility. * ping plugin: Correct the handling of the `TTL' setting. * swap plugin: Reapply a patch for Solaris. * tcpconns plugin: Portability improvements. 2008-02-18, Version 4.3.0 * collectd: Notifications have been added to the daemon. Notifications are status messages that may be associated with a data instance. * collectd: Threshold checking has been added to the daemon. This means that you can configure threshold values for each data instance. If this threshold is exceeded a notification will be created. * collectd: The new `FQDNLookup' option tells the daemon to use the full qualified domain name as the hostname, not just the host part es returned by `gethostname(2)'. * collectd: Support for more than one `TypesDB' file has been added. This is useful when one such file is included in a package but one wants to add custom type definitions. * collectd: The `Include' config option has been expanded to handle entire directories and shell wildcards. * collectdmon: The new `collectdmon' binary detects when collectd terminates and automatically restarts it again. * csv plugin: The CSV plugin is now able to store counter values as a rate, using the `StoreRates' configuration option. * exec plugin: Handling of notifications has been added and the ability to pass arguments to the executed programs has been added. * hddtemp plugin: The new `TranslateDevicename' option lets you disable the translation from device names to major-minor-numbers. * logfile plugin: Handling of notifications has been added. * ntpd plugin: The new `ReverseLookups' can be used to disable reverse domain name lookups in this plugin. * perl plugin: Many internal changes added support for handling multiple threads making the plugin reasonably usable inside collectd. The API has been extended to support notifications and export global variables to Perl plugins; callbacks now have to be identified by name rather than a pointer to a subroutine. The plugin is no longer experimental. * uuid plugin: The new UUID plugin sets the hostname to an unique identifier for this host. This is meant for setups where each client may migrate to another physical host, possibly going through one or more name changes in the process. Thanks to Richard Jones from Red Hat's Emerging Technology group for this plugin. * libvirt: The new libvirt plugin uses the `libvirt' library to query CPU, disk and network statistics about guest systems on the same physical server.

Versions prior to this may have problems in high-load situations, where the socket receive buffers overflows, resulting in gaps in the data. + Use `memcpy' when constructing/parsing a package to avoid alignment problems on weird architectures, such as Sparc. + Translate doubles to/from the x86 byte representation to ensure cross-platform compatibility. * ping plugin: Correct the handling of the `TTL' setting. * rrdtool plugin: Ensure correct handling of the `RRATimespan' option. * swap plugin: Reapply a patch for Solaris. * tcpconns plugin: Portability improvements. 2008-01-21, Version 4.2.4 * unixsock plugin: A bug in the unixsock plugin caused it not to set the permission on the socket as documented in the manpage. Thanks to Evgeny Chukreev for fixing this issue. * collectd: The documentation has been improved. 2007-12-28, Version 4.2.3 * sensors plugin: Updated the plugin to build and work with version 3 of the libsensors library. 2007-12-15, Version 4.2.2 * nginx plugin: Incorrect comparison of strings lead to a segfault when using the plugin. Thanks to Saulius Grigaliunas for fixing this. * logfile plugin: The config option `Timestamp' was handled incorrectly and basically always active. Thanks to Luke Heberling for fixing this. 2007-11-08, Version 4.2.1 * tcpconns plugin: Don't complain about a missing file if IPv6 is not enabled on the host. * snmp plugin: Fix a memory leak. 2007-10-27, Version 4.2.0 * collectd: The new config option `Include' lets you include other configfiles and thus split up your config into smaller parts. This may be especially interesting for the snmp plugin to keep the data definitions separate from the host definitions. * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics (number of connections, octets and packets for each service and destination). Thanks to Sebastian Harl for this plugin. * memcached plugin: The new `memcached' plugin connects to a memcached daemon process and collects statistics of this distributed caching system. Thanks to Antony Dovgal for contributing this plugin. * nginx plugin: The new `nginx' plugin reads the status page of an nginx daemon and saves the handled connections and requests. * perl plugin: Many changes, including the added `EnableDebugger' config option which lets you debug your Perl plugins more easily. * rrdtool plugin: Use the thread-safe RRD-library if available. Try to be more thread-safe otherwise by locking calls to the library. * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to correct the values returned by SNMP-agents. If a block is defined as `table' the instance is now optional. The sequence number is used as the type-instance in this case. The new `InstancePrefix' option allows to add arbitrary prefixes to the type-instance. * tcpconns plugin: The new `tcpconns' plugin collects the number of certain TCP connections and what state they're in. This can be used to see how many connections your FTP server has to handle or how many outgoing connections your mailserver has open. 2008-01-11, Version 4.1.6 * unixsock plugin: A bug in the unixsock plugin caused it not to set the permission on the socket as documented in the manpage.

The dependency checking has been removed from the plugins themselves to remove redundancy. * Flexible interval: The interval of collected data is now sent along with the data itself over the network, so that the interval-settings of server and clients no longer needs to match. * netlink plugin: The new `netlink' plugin connects to the Linux kernel using a netlink socket and uses it to query information about interfaces, qdiscs and classes. * rrdtool plugin: The cache is now dumped to disk in an extra thread to not block data collection. * snmp plugin: The new `snmp' plugin can read values from SNMP enabled network devices, such as switches, routers, thermometers, rack monitoring servers, etc. The collectd-snmp(5) manpage documents this plugin. * unixsock plugin: Added the `LISTVAL' command. * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency of music played with xmms. 2007-09-28, Version 4.0.9 * apcups plugin: Fix reporting of the `load percent' data. * wireless plugin: Correct the handling of cards returning signal and noise quality as percentage. * perl plugin: Fix a possible buffer overflow in get_module_name(). 2007-09-12, Version 4.0.8 * collectd: The `sstrerror' function was improved to work correctly with the broken GNU version of `strerror_r'. * collectd: Write an error message to STDERR when loading of a plugin fails. * apcups plugin: Fix the `types' used to submit the values: They still has an `apcups_' prefix which doesn't work anymore. * rrdtool plugin: Create new RRD-files with the `begin' time set to whatever the client thinks is `now'.. 2007-08-26, Version 4.0.7 * documentation: Some typos have been fixed and some information has been improved. * build system: Many fixes for detecting libraries in unusual places, such as on RedHat systems. The affected libraries are `libcurl', `libmysql', and `libupsclient'. * network plugin: Allow the `Port' option to be specified as a number (i. e. without quotes). * nut plugin: A fix allows linking the nut plugin against libupsclient, version >= 2.2.0. * processes plugin: Fix a potential segmentation fault. 2007-07-30, Version 4.0.6 * sensors plugin: Fix the ignorelist functionality: Only the `type instance' was used to match against the list, but the documentation told otherwise. This release fixes the code, so it complies with the documentation. * syslog plugin: Call `openlog' right when the plugin is loaded, so configuration messages will end up in the logging facility. * conrtib/fedora: The contributed specfile for Fedora has been updated. 2007-07-05, Version 4.0.5 * Portability: More fixes for OpenBSD have been included. 2007-06-24, Version 4.0.4 * cpu plugin: Fixed the Solaris code. * dns plugin: Fixed a build issue for OpenBSD. * interface plugin: Fixed the Solaris code. * load plugin: Fixed the alternative `/proc' Linux code. * memory plugin: Fixed the Solaris code. * oconfig: Don't require `-lfl' anymore. 2007-06-19, Version 4.0.3 * cpu plugin: Fix the Darwin / Mac OS X code. * ping plugin: Use the return value of `getpid', not its address. * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be initialized correctly. * configure: Added `--with-nan-emulation' to aid cross compilation. 2007-06-12, Version 4.0.2 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when they're given in numerically form. 2007-06-07, Version 4.0.1 * iptables plugin: A bug in the configuration routine has been fixed. Setting a comment in the configfile will no longer cause a segmentation fault. 2007-06-03, Version 4.0.0 * collectd: The plugin-infrastructure has been changed to allow for more types of plugins, namely `write' and `log' plugins. * collectd: The read-function has been changed to read many plugins in parallel, using threads. Thus, plugins generally need to use thread-safe functions from now on. * collectd: The '-t' command line options allows to perform syntax tests of the configuration file and exit immediately. * csv plugin: The new `csv' plugin handles output to `comma separated values'-files. * rrdtool plugin: The new `rrdtool' plugin handles output to RRD-files. Data can be cached to combine multiple updates into one write to increase IO-performance. * network plugin: The new `network' plugin handles IO via the network. It implements a different, much more extensible protocol which can combine many values in one packet, decreasing the number of UDP- packets being sent. It can read from and send to the network and with the appropriate configuration even forward packets to other networks. * unixsock plugin: The new `unixsock' plugin provides an interface to communicate with the daemon while it is running. Right now the commands `GETVAL' and `PUTVAL' are implemented, but more are to come. * perl plugin: The new `perl' plugin allows you to write extensions for collectd in the scripting-language Perl. * logfile plugin: The new `logfile' plugin writes logmessages to files or STDOUT or STDERR. * syslog plugin: The new `syslog' plugin sends logmessages to the system's syslog daemon. * entropy plugin: The new `entropy' plugin collects the amount of entropy currently being available to the system. * exec plugin: The new `exec' plugin forks child processes and reads back values provided by the forked processes. * iptables plugin: The new `iptables' plugin reads counters from iptables rules.

Thanks to Peter Holik for contributing this plugin. * nut plugin: The new `nut' plugin connects the upsd of the `network ups tools' and reads information about the connected UPS. * apache plugin: Support for lighttpd's `BusyServers' (aka. connections) field was added by Florent Monbillard. * collectd-nagios: The new `collectd-nagios' binary queries values from collectd, parses them and exits according to Nagios-standards. * manpages: The manpages have been improved a lot. 2007-09-28, Version 3.11.7 * wireless plugin: Correct the handling of cards returning signal and noise quality as percentage. 2007-08-31, Version 3.11.6 * processes plugin: Fix a potential segmentation fault. 2007-05-29, Version 3.11.5 * configure: Added `AC_SYS_LARGEFILE' for LFS. * ntpd plugin: Fix a potential buffer overflow. * processes plugin: Fix a bug when run under Linux 2.4. All processes were accounted as `zombies'. 2007-04-10, Version 3.11.4 * dns plugin: Change the order of includes to make the plugin compile under FreeBSD. 2007-03-30, Version 3.11.3 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead of the unused `COLLECT_KSTAT'. 2007-02-11, Version 3.11.2 * plugin: Catch NULL-pointer and try to fix them. Otherwise the NULL-pointer may have been passed to `printf' which causes a segfault with some libcs. 2007-02-10, Version 3.11.1 * df plugin: Some wrong defines have been fixed so the plugin works under Solaris again. * dns plugin: The usage of a struct has been fixed to work with non-GNU libcs. * processes plugin: Some missing defines have been added so the plugin compiles cleanly under FreeBSD and presumably other UNIXes. 2006-12-22, Version 3.11.0 * collectd: The new command line option `-P' makes it easier for distributors to change the location of PID-files. * collectd: The daemon shuts down faster now which makes it easier to write init.d-scripts for it. * apache plugin: Increase the buffersize to 16k, because the 4k buffer caused problems every now and then. * df plugin: New config options allow to ignore certain mountpoints, filesystem types or devices. * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic and interprets it. It collects traffic as well as qtype, opcode and rcode counts. * email plugin: Sebastian Harl has contributed this plugin which counts received mails in categories (e. g. ham, spam, virus), spam score (as given by SpamAssassin) and check types. * mbmon plugin: Flavio Stanchina has contributed this plugin which uses `mbmon' to gather information from sensors on the motherboard. * processes plugin: Collect detailed statistics for configured processes, that's process and thread count, CPU usage, resident segment size and pagefaults. * multimeter plugin: Peter Holik contributed a new plugin which queries multimeters. * sensors plugin: Lubos Stanek has put much effort into improving this plugin, including `extended naming', collection of voltage values and the possibility to ignore certain values. 2006-12-21, Version 3.10.4 * Max Kellermann has identified a bug in the server routine: When opening a socket fails the daemon will (re)try opening the socket in an endless loop, ultimately leading to a `EMFILE' error. 2006-11-04, Version 3.10.3 * Lubos Stanek has identified a bug in the ntpd-plugin: When the ntpd's reply was sent in more than one packet, the buffer size was calculated incorrectly, resulting in the reading of uninitialized or freed memory. 2006-11-01, Version 3.10.2 * The sample config file has been improved. * Errors in the manpages have been corrected. * The ping-plugin now adds hosts during initialization, not during startup. This speeds up startup when no network connectivity is available. Also, the hosts are being added later when the network is available. * Improved BSD-support for the df-plugin. * Fixed syntax errors in the swap-plugin for Mac OS X. * Fix a wrong structure being passed to `getnameinfo' in the ntpd- plugin. * Don't disable the mysql-plugin if connecting to the database fails during initialization. Instead, try again in increasing intervals. 2006-07-19, Version 3.10.1 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but the apcups cannot be reached, unconnected sockets will pile up and eventually lead to `Too many open files' errors. 2006-07-09, Version 3.10.0 * The `disk' plugin has been ported to Darwin. * The `battery' plugin should work on many Apple computers now. * The `traffic' plugin can now ignore certain interfaces. Also, statistics for sent/received packets and errors have been added. * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks to Anthony Gialluca for contributing this plugin and providing me with a test environment :) * A plugin for monitoring an NTP instance and the local clock drift has been added. 2006-06-25, Version 3.9.4 * The Solaris code in the `swap' plugin has been changed to reflect the numbers returned by `swap -s'. Thanks to Christophe Kalt for working this out. * The debugging system has been fixed to work with the Sun libc. * When built without librrd the variable `operating_mode' could be uninitialized. Thanks to David Elliot for reporting the bug. 2006-06-01, Version 3.9.3 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other operating systems also profit from the changes, but I wasn't able to check that. * Changed the build system to find the netinet-includes under FreeBSD and therefore successfully build the `liboping' library there. 2006-05-09, Version 3.9.2 * Applied a patch to the `liboping' library. Due to a bug in the sequence checking the `ping' plugin stopped working after approximately 7.6 days. 2006-05-09, Version 3.8.5 * Applied a patch to the `liboping' library. Due to a bug in the sequence checking the `ping' plugin stopped working after approximately 7.6 days. 2006-04-21, Version 3.9.1 * Build issues with Solaris and possible other architectures have been resolved. * Problems when building the `apache'-plugin without `libcurl' have been resolved. * A bug in the `ping' plugin has been fixed. Sorry folks. 2006-04-02, Version 3.9.0 * A plugin to monitor the Apache webserver has been added. * A plugin to collect statistics about virtual servers using VServer. Thanks to Sebastian Harl for writing this plugin :) * A plugin for wireless LAN cards has been added. It monitors signal strength, link quality and noise ratio.. * A plugin for Apple hardware sensors has been added. * An option to compile collectd with different `step' and `heartbeat' settings has been added. The size of RRAs is no longer static but calculated based on the settings for `step' and `width'. * The `ping' plugin can now be configured to use a certain TTL. * A plugin to monitor the hardware sensors of Apple computers has been added. * The plugins `cpu', `memory', `processes' and `traffic' have been ported to Mach/Darwin (Mac OS X). * The `log mode' has been contributed by Christophe Kalt. It writes the data into text files rather than RRD files. 2006-04-09, Version 3.8.4 * Applied patch by Vincent Stehlé which improves the disk-name resolution in the `hddtemp' plugin for Linux systems. 2006-04-02, Version 3.8.3 * Applied a patch by James Byers: The MySQL plugin was not working with MySQL 5.0.2 or later. 2006-03-14, Version 3.8.2 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by the GNU libc, because it points to `/etc/fstab' rather than `/etc/mtab'. 2006-03-13, Version 3.8.1 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris. * Fixes in the debian `postinst' and `init.d' scripts. 2006-03-09, Version 3.8.0 * The `ping' plugin no longer uses `libping' but a self written library named `liboping'. With this library it's possible to ping multiple IPv4 and IPv6 addresses and hostnames - in parallel. 2006-02-18, Version 3.7.2 * A simple bug in the `battery' plugin has been fixed. It should now work with ACPI based batteries as well. Thanks to Sebastian for fixing this. * Fixing a bug that prevented collectd to be built without librrd. Thanks to Werner Heuser for reporting it. 2006-02-04, Version 3.7.1 * The new network code has been improved to build with older versions of glibc. * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks to Tommie Gannert for this patch. 2006-01-30, Version 3.7.0 * The `battery' plugin has been added. It collects information about laptop batteries.. * The MySQL plugin has been improved: It now writes two more RRD files, `mysql_qcache.rrd' and `mysql_threads.rrd'. * The `cpufreq' plugin now reads another file since the file it did read so far causes much overhead in the kernel. Also, you need root to read the old file, but not to read the new one. * The `hddtemp' plugin can now be configured to connect to another address and/or port than localhost. * The `df' plugin now prefers `statvfs' over `statfs'. * The network code has been rewritten. collectd now supports unicast and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can be set in the configfile. 2006-01-24, Version 3.6.2 * Due to a bug in the configfile handling collectd wouldn't start in client mode. This released fixes this. 2006-01-20, Version 3.6.1 * Due to a bug in `configure.in' all modules and the binary were linked against `libmysqlclient'. This issue is solved by this release. 2006-01-17, Version 3.6.0 * A config file has been added. This allows for loading only specific plugins. * A `df' plugin has been added. * A `mysql' plugin has been added. * The `ping' plugin doesn't entirely give up hope when a socket error occurred, but will back of and increase the intervals between tries. 2006-01-21, Version 3.5.2 * Fixed yet another bug in the signal handling.. Stupid typo.. * Improved the ping plugin to not give up on socket errors (backport from 3.6.0). 2005-12-18, Version 3.5.1 * The PID-file is now deleted correctly when shutting down the daemon. * SIGINT and SIGTERM are now handled correctly. 2005-12-16, Version 3.5.0 (Revision 326) * A bug in the `load' module under Solaris has been fixed. * The `users' module has been contributed by Sebastian Harl. It counts currently logged in users. * The CPU module now works under FreeBSD without the use of `libstatgrab', however SMP support is missing. * The default directories for the RRD files and the PID file now depend on the compile time setting of `localstatedir'. 2005-11-15, Version 3.4.0 (Revision 236) * A PID-file is written to /var/run upon startup. Thanks to `Tommie' from gentoo's bugzilla for writing the patch. * The build dependency for librrd has been removed. Binaries built without librrd are client-only and will multicast their value as with the `-c' argument. * A patch by Peter Holik adds a module for monitoring CPU frequencies. * The newly introduced `-f' switch prevents daemon initialization (forking, closing standard filehandles, etc.) Thanks to Alvaro Barcellos for this patch. 2005-11-04, Version 3.3.0 (Revision 216) * New modules have been added: - `serial', for monitoring traffic on the serial interfaces - `nfs', for graphing NFS procedure calls - `tape', traffic from/to tape devices * The memory.rrd now accepts more than 4Gig of memory. 2005-10-26, Version 3.2.0 (Revision 200) * Support for graphing the processes has been added (thanks to Lyonel Vincent) * If reading from hddtemp fails collectd will increase the time between polls up to one day. * The init.d files have been improved. * Problems with the spec file have been fixed. 2005-10-16, Version 3.1.0 (Revision 194) * Added the `setsid' syscall to the startup code. * Support for hddtemp has been added (thanks to Vincent Stehlé) 2005-09-30, Version 3.0.0 (Revision 184) * The ability to send/receive data to/from the network (think multicast) has been added. * Modules have been split up into shared libraries can be loaded at runtime. The biggest advantage is that the core program doesn't need to be linked against an external library. * A patch by George Kargiotakis has been applied: It fixes the sensors behaviour then more than one sensor is being queried. 2005-09-16, Version 2.1.0 (Revision 172) * A module for swap statistics has been added. 2005-09-09, Version 2.0.0 (Revision 135) * Filenames can no longer be configured at program startup. The only options as of this version are the directory and ping hosts. * CPU statistics now include Wait-IO. If provided under Linux IRQ and Soft-IRQ statistics are added to `System'. * Diskstats now collect read and write bytes, not sectors. * Ping statistics can now be collected for more than one host. There is no default any more: If no host is given no host will be pinged. * A self-written patch for libping has been applied so it builds cleanly. 2005-09-01, Version 1.8.1 (Revision 123) * Much improved configure-script: libraries and features may now be disabled. * More detailed warnings/error messages when RRD update fails. 2005-08-29, Version 1.8.0: * Support for collecting disk statistics under Solaris. 2005-08-25, Version 1.7.0: * Support for libstatgrab[1] for load, memory usage and network traffic. CPU- and disk-usage are not (yet) supported, since libstatgrab returns insufficient information. I will contact the authors. * Improved the CPU-initialization code for Solaris. Apparently CPUs aren't necessarily counted linear which is now handled correctly. [1]: http://www.i-scream.org/libstatgrab/ 2005-08-21, Version 1.6.0: * Basic support for Solaris: System load and cpu-usage can be collected under Solaris, too. Other stats will follow later. * Many fixes in the autoconf-script * Collection/Museum scripts have been added under contrib/museum * collectd may now be started in unprivileged mode, though ping statistics will not work. 2005-07-17, Version 1.5.1: * Diskstats-RRDs now use major/minor for naming. Some systems have weird strings as disk-names.. 2005-07-17, Version 1.5: * A new module, diskstats, has been added. It collects information about the disks and partitions. 2005-07-11, Version 1.4.2: * The meminfo module has been changed to work with more platforms and/or kernel versions. 2005-07-10, Version 1.4.1: Correct traffic stats * The traffic rrd-file is now created with DS-type `COUNTER' which I forgot to correct when I changed that module. 2005-07-09, Version 1.4: More traffic stats * Traffic is now collected for all interfaces that can be found * Temperature-statistics are read from lm-sensors if available 2005-07-08, Version 1.3: CPU stats * Collecting CPU statistics now 2004-07-12, Version 1.2: Using syslog * collectd is now using the syslog facility to report errors, warnings and the like.. * The default directory is now /var/db/collectd 2004-07-10, Version 1.1: Minor changes * Nothing really useful to say ;) 2004-07-09, Version 1.0: Initial Version * The following modules are provided: * Load average * Ping time * Traffic * Memory info
