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 Sjoerd van der Berg for contributing this plugin. * irq plugin: The new `irq' plugin collects the IRQ-counters. 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. 2007-05-29, 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 starup 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 moniroting 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 `hearbeat' 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 unter 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. Thankt 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 occured, 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 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 failes 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 privided 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 failes. 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 neccessarily 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 unter Solaris, too. Other stats will follow later. * Many fixes in the autoconf-script * Collection/Museum scripts have been added unter 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 mofule 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 usefull to say ;) 2004-07-09, Version 1.0: Initial Version * The following modules are provided: * Load average * Ping time * Traffic * Memory info
