But there may be cases where that is useful. For example if you have a single host on a cluster head node, and want multiple different groupings (i.e. ganglia "clusters") to be exported to a gmetad system that is outside of the cluster. For example: Monitor Host --> Head node ---> compute gmond aggregator (gmetad) (gmond aggregator) +-> storage gmond aggregator Currently, you have to run two different gmond processes on the head node, and poll both independently. >Also note that even though you have a separate multicast address for each >cluster, the port still has to be unique.
