Windows support. Gmond can send metrics on multiple unicast and multicast channels. Gmetric parses gmond configuration file to send metrics. Gmond has been completely rewritten to use the Apache Portable Runtime library. IPv6 support has been added for gmond. A new gmond configuration file format allows for complete control over metric collection, access control lists, and bandwidth usage. Solaris gmond properly runs in the background as a non-root user. Mixing operating systems on the same I/O channel is okay now. The XML DTD has been fixed. Darwin support has been updated. A FreeBSD gmond memory leak has been fixed.
This release features a new gmetad cleanup thread that
prevents memory leaks in certain cases. Gmetad now also
presents a
more accurate "TN" in XML streams.
The host DMAX attribute is now honored allowing you to specify a timeout for dead hosts. Ganglia now compiles on 64-bit versions of FreeBSD. A bug has been fixed which caused nodes to falsely be marked as down. An RPM dependency on librrd has been removed.
All standard metrics are now reported on FreeBSD.
This release also fixed a bug that allowed a specially
crafted UDP packet to cause segfaults in all gmond
processes on a multicast channel. The
documentation is now included in the distribution as
ganglia.html and README.
gmetad is now interactive, allowing for efficient primitive subtree queries of the XML tree. The Web front end has been updated to work with gmetad for very significant speed improvements when loading Ganglia Web pages. gmetad has also been improved to handle clusters with varying clocks (the graph timescales are no longer locked). The time and value thresholds for the gmond network monitors have been increased to prevent unnecessary network traffic. gmond is also more stable and correct on IRIX.
