Changes

Release 4.0.0

Released on Sunday, June 03, 2007.

  • 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.

Release 4.0.1

Released on Thursday, June 07, 2007.

  • IPTables plugin: A bug in the configuration routine has been fixed. Setting a comment in the configfile will no longer cause a segmentation fault.

Release 4.0.2

Released on Tuesday, June 12, 2007.

  • hddtemp and ntpd plugin: Corrected the parsing of port numbers when they're given in numerically form.

Release 4.0.3

Released on Tuesday, June 19, 2007.

  • 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.

Release 4.0.4

Released on Sunday, June 24, 2007.

Release 4.0.5

Released on Thursday, July 05, 2007.

  • Portability: More fixes for OpenBSD have been included.

Release 4.0.6

Released on Monday, July 30, 2007.

  • 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.

Release 4.0.7

Released on Sunday, August 26, 2007.

  • 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.

Release 4.0.8

Released on Wednesday, September 12, 2007.

  • 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.
  • APC UPS 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..

Release 4.0.9

Released on Friday, September 28, 2007.

  • APC UPS 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().
