Dear Ganglia community:

For those who have been following our development, you know that we
have recently created a new branch for 3.1, which when stabilized,
will become the first release in the 3.1.x series (probably will be
called 3.1.1).

I just cut the first snapshot and the files are available here:

http://www.ganglia.info/snapshots/3.1.x

** This is a development snapshot and is not ready for production use yet **

For those who are interested in performing a test upgrade from an
older installation (3.0.x), the RPM will automatically move your
current configurations (gmond.conf, gmetad.conf) to the new
configuration location (/etc/ganglia).  However, for gmond, the 3.0.x
conf will not work.  Please use the patch file gmond-3.1.patch
(available in the above URL) to patch your gmond.conf prior to
starting, otherwise gmond will fail to startup.

Some development highlights:
- New C/Python module support for dynamically plugging metrics into
gmond directly
- Memory metrics are converted from int to float to get around issue of > 4TB
- Metrics come with additional data, like group, descriptive title
which are used in the frontend
- Metrics in frontend metrics view are now grouped and can be hidden
(javascript must be enabled)
- Manpages for all ganglia components (gmond, gmetad, gmetric, gstat)
are now included in RPM
- apr, expat, confuse libraries are removed from source tree. Ganglia
will dynamically use system provided libraries by default, this can be
overridden using ./configure options
- Code for report graph creation is now modularized in graph.d/
directory under docroot which facilitates creation of new custom
report graphs
- Added support for DragonFlyBSD
- Numerous bugfixes

Please help the developers test this snapshot especially if you use
Ganglia on non-Linux platforms.  This will help us stabilize the tree
quicker and get the release out sooner.

If you encounter any issues, please get in touch with the developers
at [EMAIL PROTECTED]

Thanks for your support!

Bernard
(on behalf of the Ganglia Development Team)
