Changes

Release 4.1.0

Released on Saturday, September 01, 2007.

  • Build system: The build system has been changed to automatically disable all plugins, which are missing dependencies. 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.

Release 4.1.1

Released on Wednesday, September 12, 2007.

  • Build system: The detection of `libnetlink' has been improved.
  • collectd: The documentation has been fixed in numerous places.
  • Exec plugin: Setting the group under which to run a program has been fixed.
  • 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 4.1.2

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().
  • build system: Further improve the detection of libraries.
  • Netlink plugin: Build issues under some older versions of the Linux includes (i. e. Debian Sarge) have been fixed.

Release 4.1.3

Released on Wednesday, October 24, 2007.

  • collectd: A build issue under Solaris has been resolved by renaming data types.
  • RRDtool plugin: Use the thread-safe RRD-library if available. Try to be more thread-safe otherwise by locking calls to the library.

Release 4.1.4
