guys- i just created what i think will be the 2.6.0 release at http://matt-massie.com/ganglia/2.6.0/
i've updated the rpm installation to check if the person is upgrading from the old 2.5.x gmond and if so it issues the following warning.
----------------------------------------------------------- IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT ----------------------------------------------------------- It appears that you are upgrading from ganglia gmond version 2.5.x. The configuration file has changed and you need to convert your old 2.5.x configuration file to the new format. To convert your old configuration file to the new format simply run the command: % gmond --convert old.conf > new.conf This conversion was not made automatic to prevent unknowningly altering your configuration without your notice. ---i've also updated the announcement based on the feedback that i've received from the list. please take a look at it one last time and let me know if it okey dokey. i think everyone is listed who deserves credit (if not please let me know).
i think that i'm going to announce this release this week. i'm leaning toward not releasing any betas. if there are problems with 2.6.0, we can fix them in 2.6.1. we worked really hard to get this release out and i feel it's production quality. if anyone out there thinks otherwise please let me know (i really don't want to release poor quality software).
here is the latest announcement... i look forward to your feedback! ______ ___ / ____/___ _____ ____ _/ (_)___ _ / / __/ __ `/ __ \/ __ `/ / / __ `/ / /_/ / /_/ / / / / /_/ / / / /_/ / \____/\__,_/_/ /_/\__, /_/_/\__,_/ /____/ Distributed Monitoring System The Ganglia Development Team is pleased to announce the release of Ganglia 2.6.0 which features... Windows Support Ganglia now runs on Windows. There is support for all standard metrics except for disk_free, disk_total, max_part_used and cpu_num (support will be added in future releases). We have also created a windows installer which allows you to easily add the ganglia monitoring service to any Windows NT/2000/XP machine. Currently, there is no support for multicast on windows but this will be added in the future. Special thanks to Carlo Marcelo Arenas Belon for providing metric code which makes native windows calls to collect the majority of metrics. Unicast Support Ganglia now allows you to send status messages over unicast routes instead of a single multicast channels. This capability gives you greater flexibility in building your monitoring overlay and allows ganglia to run on networks that are not multicast-enabled. Moreover, you can specify as many unicast and multicast channels as you like. Whenever a message is sent each and every channel will receive the message. This feature gives you much more power in grouping machines. Gmetric commandline tool parses the configuration file Gmetric now parses the gmond configuration file and sends metric information to all unicast and multicast udp channels specified. Apache Portable Runtime library The Apache Portable Runtime (APR) library is the library underlying the Apache web server which provide memory pools, networking io, hash tables and arrays in a very portable manner. APR now serves as the heart of the new ganglia monitoring daemon to expand portablility, improve reliability and provide new features like IPv6 address support. More powerful and flexible configuration The configuration file for "gmond" has changed. This change was necessary to provide you with a more flexible and powerful framework in which to configure gmond. There is a man page for gmond.conf (see man gmond.conf) which explains the new format. To convert an old 2.5.x configuration file to the new format simply run % gmond --convert old.conf > new.conf This new format allows you to specify multiple unicast and multicast channels to send and receive monitoring information, provides much more flexible access control lists, and allows you the power to specify exactly what metric you want to collect on each machine. Special thanks to the developers of confuse (http://www.nongnu.org/confuse/) for building such a great file parser. Configuration analysis gives bandwidth usage There is a new option for gmond which allows you to get an estimate of the bandwidth that gmond will use given a particular configuration. % ./gmond -b /etc/gmond.conf 7.945789 bytes/sec This feature allows you to budget how much bandwidth you will use for monitoring your machines for a given configuration (see man gmond.conf). More powerful Access Control mechanism In the old 2.5.x world, the only access control mechanism available was a list of trusted_hosts. Ganglia now supports very elaborate access control lists that allow you to specify an ip and mask (for filtering subnets) and outline the default policy (see man gmond.conf for details). RPM names were renamed on Linux The RPM names have been renamed to make them simpler ganglia-monitor-core-gmond => ganglia-gmond ganglia-monitor-core-gmetad => ganglia-gmetad ganglia-monitor-core-lib => ganglia-devel ganglia-webfrontend => ganglia-web Major cleanup of ganglia-devel Lots of unneccessary headers where removed from libganglia and a ganglia-config script was added for application that link against ganglia (see ganglia-config --help for details). ganglia-devel now installs only the following files /usr/bin/ganglia-config /usr/include/ganglia.h /usr/lib/libganglia.a /usr/lib/libganglia.la /usr/lib/libganglia.so Solaris gmond doesn't have to be run as root anymore Special thanks to Adeyemi Adesanya for switching the Solaris metric gathering code from kvm to kstat, eliminating the need to run gmond as root. Gmond on Solaris can not setuid to any user that you configure it to (see man gmond.conf for details). Fixed bug that required Solaris systems to run in debug mode Gmond wasn't properly daemonizing on certain Solaris systems requiring that it be run in debug_mode with the output redirected to "/dev/null". This bug no longer exists. Fixed a memory leak on FreeBSD Fix a memory leak in find_disk_space() as reported by Glen Beane. - Overhaul makenetvfslist() a bit to fix a leak in low memory situations, reduce duplicated code, and streamline error handling. - Fix a few compiler warnings. All metric collection functions are in a standalone library All the metric code has been moved to ./srclib/libmetrics in the ganglia distribution. Special Thanks to Martin Knoblauch for his hard work in cleaning up the code. Darwin metric collection improved Darwin now supports mem_total and has better process accounting. Special thanks to Sebastian Hagedorn, Glen Beane, Joshua Durham, Eric Wages and Brian Peterson for their work on MacOS X. Potential memory leak fixed in gmetad Marcelo Veiga Neves determined how a memory leak was possible for metrics sent via gmetric. Federico Sacerdoti applied a fix to prevent any leaks. All web scripts are in the ./web directory of the distribution now The PHP web scripts have been incorporated into the main ganglia distribution. Minor bug fixed added by Ramon Bastiaans and Jason Smith. All ganglia communication protocols are defined in ./lib/protocol.x To help in integrating ganglia communications into other applications, all communcation protocols are defined in ./lib/protocol.x. This XDR description file can be parsed by rpcgen, for example, to build XDR code for sending and receiving status messages. Added a --foreground flag to gmond Allows you to force gmond to run in the foreground. Gmetad on Solaris bug fixed David Wood fixed a bug in creating directories on Solaris. -matt -- PGP fingerprint 'A7C2 3C2F 8445 AD3C 135E F40B 242A 5984 ACBC 91D3' They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. --Benjamin Franklin, Historical Review of Pennsylvania, 1759
