Improvements

Bug fixes

Version 3.5.0 (Release date 2013-02-14)

  • gmond uses a separate thread to service gmetad requests. This should improve performance
  • Updates to a number of core Python collection modules

Version 3.4.0 (Release date 2012-05-24)

Minor release for slightly disruptive changes

  • web
  • now distributed as a separate source tarball, web/ tree is not present in the ganglia-3.4.0 tarball
  • gmond:
  • setgid() and initgroups() are invoked when setuid() is invoked - gmond no longer runs in root group (there may be side-effects from this change)
  • new UDP RX channel parameter `buffer' to set the socket buffer size - larger values can help reduce packet loss

Version 3.3.7 (Release date 2012-05-02)

Hotfix startup issues

Version 3.3.5 (Release date 2012-04-04)

Summary: the 3.3.1 release was slightly broken as the correct version number wasn't embedded in configure.in with undesirable effects for some people trying to build packages. The 3.3.5 release fixes that issue and returns to the autotools dist mechanism for consistency with prior releases. There is a mixed bag of minor bug fixes across almost all modules as summarised in the release notes.
