Typically the hostname used by ganglia is derived from a reverse DNS lookup
of the IP of the node reporting metrics. When I see this it's typically
missing PTR records. Related to that, if you have multiple PTR records for
a given IP the hostname used can change on subsequent restarts of gmond &
cause you to have multiple host entries for a single IP.
