The authority URL is mostly used to locate the parent grid's URL when
you've traversed into a child grid.

In your situation, for Grid A, it doesn't really matter whether the
authority is http://www.myganglia.com or
http://ganglia-master.myganglia.com since they're pretty much the same
thing.  However, assuming you will be adding additional servers to
your load balancer, you probably want to use the alias
http://www.myganglia.com as the authority.

For Grid B, since you have one host anyway, then the authority should
be ganglia-master2.myganglia.com.

Hope this helps.

BTW I am curious how you are planning to setup load balancing with gmetad.

Cheers,

Bernard
