I would definitely like this functionality. At first, I thought maybe this could be a new gmond.conf option, but then I didn't like the idea that every host would need a different gmond.conf file just to change the hostname. Maybe passing the hostname as a metric might work. With the new loadable module support, any type of logic could be implemented to let a host dynamically determine its "hostname". (Ganglia could even supply a default module that just did reverse DNS to find the hostname.) Of course, one drawback to this is that the "hostname" metric might not be the first metric sent (or sent at all), so the receiving gmond might still have to perform reverse DNS as a backup. Or maybe the gmond.conf file should just allow an option like "hostname_command" that lets you specify an external command to run which then returns the host's name.
