3.3.7
* gmond
- BUG100: fails to start in Solaris zones
- fails to start when no address on the network interface (added
retry_bind parameter)

hearing any data
3.3.5
* General
- Return to the use of autotools (make dist) for building the release
- Release with a valid version number in configure.in
* Gmetad
- Fix for gmetad buffer overflow with metric value of DOUBLE_MAX
* Gmond python modules
- multi traffic module has been replaced with multi interface which
correctly reports all interfaces
* Gmond
- Fix for issues/11
- Expose some useful functions in the public C API to assist module
developers
3.3.1
* Web
- Graph Zooming off when Ganglia Web server and web browser in different
time zones
- Metrics chooser in cluster view now provides metric drop down in
addition to autocomplete
- Ability to specify default size for graphs in Views
Gmetad
- You can now disable RRD writing - useful if you are using Ganglia only
to feed Graphite
- Export to graphite now handles spaces in metrics, groups
- Minor code clean up and fixes
* Gmond
- Diskstat python module incorrect IO time reporting has been fixed.
3.3.0
* Web UI shipped with Ganglia has been upgraded to the Ganglia Web
2.0 interface. Changes to web UI from Gweb 2.2.0 are as follows
- Additional Nagios integration scripts
- Contributed by Etsy - stacked graph in the cluster view
- Ability to hide/show events on individual graphs or whole pages
- Numerous bug fixes and small enhancements
* metric names are sanitized to avoid breaking gmetad/UI when characters
such as <, > are supplied. Those are now replaced with underscores
* gmetad supports sending metrics to graphite. Uncomment proper section
of gmetad.conf to enable
* Default RRD resolution changed. It affects only newly created RRDs. To
change to old behavior please modify the RRA field in gmetad.conf
* Number of Python modules from Ganglia gmond_python_modules repository
have been included such as disk statistics, individual interface
statistics, etc. Most of the modules are disabled. To enable rename
the files in /etc/ganglia/conf.d.
* sFlow has been enhanced to support Virtual machine pool/Java
VM/Memcache/Apache/NGINX/Tomcat and node.js metrics. You can read more
at sFlow blog
3.2.0
* sFlow support - more and even more
* hostname/ip override - you can specify an arbitrary host name and IP
to be shown in the UI.
* FreeBSD patches
* Python module improvements
* Bugfixes and improvements over 3.1.7
3.1.7:
* Fix build support for RHEL5/issue with commas in CFLAGS
* multicpu module: show CPU utilization as a value between 0-100% for
each core
3.1.3 - 3.1.6:
* Merge commit 1966 from trunk to fix "contrib/removespikes.pl"
* Bootstrapping with Debian 5.0 (lenny) versions of autotools for
this and future releases.
* Require user to explicitly specify sysconfdir when building from source,
due to the fact that the old behavior was not consistent with the
documented behavior.
* Configuration files and scripts are now created during the install phase
rather than during configure. This allows values such as @sysconfdir@
to be used in the template configuration files.
* Abolish the use of release names - only release numbers will be used
to distinguish versions in future
* libmetrics: workaround system header conflict in DFBSD >= 2.4 (BUG245)
* Use PCRE regex matching to configure metrics using the name_match directive
* rrdcached support
* gmetad now uses apr and the sleep intervals between polls are randomized
in a way that supports shorter polling intervals
* FreeBSD support: fixes for crashes and disk statistics (BUG153)
* Further tweaks to Solaris build support (remove C99 hack)
* Eliminate conflict with ncpus symbol name on older Solaris
* AIX support: determine if the host is a virtual server (BUG226)
* AIX support: setting linker flags (BUG227), add -lm
* AIX support: tweaks for AIX >= v6.1
* AIX support: revised init scripts for gmond and gmetad
* Check for Python.h explicitly
* Include the necessary Python files in the distribution tarball, regardless
of how BUILD_PYTHON is set (r2215).
* Remove references to GNU toolchain in documentation
* Fortify write_data_to_rrd against overflows
* Web interface: minor formatting changes
* mcast_if implementation tweaked so that the send channel will be bound
to the IP of the outgoing interface
* Documentation updates relating to the options for multihomed hosts,
particularly bind, bind_hostname and mcast_if
* gmond: Limit the use of APR_POLLSET_THREADSAFE to Linux >= 2.6
* gmond: improve/revert setuid behavior in configure script
* gmond: Fix the allow_extra_data configuration directive (BUG199)
* gmond: Ensure that a complete XML dump is delivered before closing
the send socket. Submitted by: Jerry <adawzq 126 com>
* gmond: add bind and bind_hostname parameters for udp_send_channel()
* gmetad: BUG232: eliminate case-sensitive hostname bug, user can choose to
maintain legacy behavior though.
* gmond: BUG237: revise fix for segfault on Solaris where first CPU not in
slot 0
* gmond: support for HUP signal on platforms with execve
* gmond: status module: return gmond version info as string metrics
* gmond: Check return status of apr_pollset_create. Use
APR_POLLSET_THREADSAFE on Linux.
* build: various configure options: Solaris 8 with Sun Studio 11 support,
extra modules for static linking, default setuid, release number,
build multicpu and status during static builds, support for
SYSCONFDIR (BUG16)
* RPM: include status module, allow packager to supply own gmond.conf
* build: Look in lib64 rather than lib for apr, confuse and expat on x86_64
