For a full description of the bug fixes and enhancements that are included in the 3.1.7 release as well as upgrade information, please see the current release notes at:

http://ganglia.wiki.sourceforge.net/ganglia_release_notes

Supported platforms:

• Linux (Fedora/RedHat/CentOS, Debian, Gentoo, SuSE/OpenSuSE)
• [Open]Solaris
• FreeBSD
• NetBSD
• OpenBSD
• DragonflyBSD
• Cygwin (no support for DSO yet)
• AIX (initial support for DSO now available – please provide feedback)

Please read all the README, INSTALL and other available documentation (http://ganglia.wiki.sourceforge.net) as a lot of things have changed since version 3.0. Use good deployment practices when upgrading from 3.0.x to make sure that you do not mix gmond 3.0 and 3.1 nodes in the same cluster (as defined by a multicast address or unicast collector node). The protocol that allows gmond nodes to communicate within the same cluster, has changed. However the XML packets that are passed between gmond and gmetad have remained compatible from 3.0.x to 3.1.x, allowing a 3.1.x gmetad to continue to pull data from an older 3.0.x gmond cluster.

[Update: Initial support for DSO is available on AIX]

(There is a known bug with 3.1.0 gmetad aggregating XML data from another 3.1.0 gmetad — if your environment requires this feature, wait for 3.1.1 to be released. Alternatively, a patch has been developed and is available here)

The main features of this release are:

• Introduction of a modular metric interface for C and Python (DSO support)
• Scriptable metric module support with Python
• All pre-existing metrics (CPU, network, disk, memory, etc.) converted to metric modules
• Introduction of new metric modules multicpu, multidisk and tcp_conn status
• Modular frontend graph support
• Metric groups which can be viewed or hidden as desired
• Additional scaling capacity for systems with memory greater than 4TB
• Platform support for DragonFlyBSD
• Improved native metric support for Windows (Built with CygWin)
• Bug fixes and Enhancements

Supported platforms:

• Linux (Fedora/RedHat/CentOS, Debian, Gentoo, SuSE/OpenSuSE)
• [Open]Solaris
• FreeBSD
• NetBSD
• OpenBSD
• DragonflyBSD
• Cygwin (no support for DSO yet)
• AIX (no support for DSO yet)

Please read all the README, INSTALL and other available documentation
(http://ganglia.wiki.sourceforge.net) as a lot of things have changed since
3.0.7. Use good deployment practices when upgrading from 3.0.x to make sure
that you do not mix gmond 3.0 and 3.1 nodes in the same cluster (as defined
by a multicast address or unicast collector node). The protocol that
allows gmond nodes to communicate within the same cluster, has changed.
However the XML packets that are passed between gmond and gmetad have
remained compatible from 3.0.x to 3.1.x, allowing a 3.0.x gmetad to continue
to pull data from a newer 3.1.x gmond cluster.

For those who are interested in upgrading from a 3.0.x installation, your
current gmond and gmetad configuration files will need to be moved from their
current location to /etc/ganglia. If you are attempting the upgrade via an
RPM, the RPM will automatically move your current configuration file to the
new location. However, for gmond, the 3.0.x conf file will not work. Please
use the patch file gmond-3.1.patch available at
http://www.ganglia.info/releases/ to patch your gmond.conf prior to
starting, otherwise gmond will fail to startup.

There are several known issues with the current release which include the
following:

• no support for C++ to create DSO modules
• no spoofing from modular metrics (use gmetric if spoofing is needed)
• race condition for tcpconn python metric module (affects gmond -m)
• libdir issues related to building for 64bit platforms
• known build issues for platforms:
  • Darwin (AKA MacOS/X)
  • HPUX
  • Tru64 (AKA OSF/1)
  • Irix

Many of the above issues are being addressed and patches will be applied for
the next minor release of Ganglia 3.1.x. In addition more information about
the current official release, can be found on the Ganglia wiki at

This is a bugfix release which fixes bugs that were introduced in 3.0.6 as well as memory leaks in gmond.

Summary of bugfixes in 3.0.7:

• [web] Host view metric graphs’ “now (x.xx)” number is always 0.00

• [web] “Show Hosts” toggled did not work

• [gmond] Fix memory leak from network metrics on Linux (thanks Kumar Vaibhav for reporting)

• [gmond] Fix spoof memory leak (thanks Martin Hicks for the patch)

http://sourceforge.net/project/showfiles.php?group_id=43021&package_id=35280

This release includes a security fix for web frontend
cross-scripting vulnerability.

All Ganglia web frontend users are strongly recommended to
upgrade to this version. In most cases the version of the
frontend does not need to match the version of gmetad and/or
gmond — if problem arises, please drop us a note at
ganglia-general@lists.sourceforge.net.

Special thanks to Romain Wartel at CERN for discovering the
vulnerability and reporting it to us and to Alex Dean for
stepping up with the fix so quickly.
