Thanks a lot. What some people do is run multiple gmonds on the central gmetad server each talking to different cluster gmonds. That way, your gmetad can query the gmond running on localhost (but via different ports) using the data_source directive. Would this work for you? In a dynamic environment, remember to set TTL for hosts so that when they die, they are automatically pruned from the list of hosts in a cluster.
