It is considered "chatty" for the network if you use multicast.
However, Ganglia also supports unicast.  For more information you can
refer to our wiki:

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

If you have more specific questions, please feel free to email us at
our mailing-list:

https://lists.sourceforge.net/lists/listinfo/ganglia-general

Or you can re-post with a different topic here, and I'll try my best
to answer them :-)

P.S. If you could please refer me to the source which mentioned
"ganglia induces severe communications overhead", I would very much
like to look it up.

Cheers,

Bernard
