I see. So I need a separate IP AND A SEPARATE PORT. Got it. Also, I use a single gmond in each cluster to aggregate the single cluster. I configure the gmetad to talk to only gmond from each cluster. Is that wrong?

That's what the gmetad daemon is for. Also note that even though you have a separate multicast address for each cluster, the port still has to be unique. The port is what gmetad and the web frontend use to distinguish between clusters. You get really weird results if multiple data_source lines use the same port. An ideal configuration might be: Each of the 5 clusters has a unique gmond.conf, with its own multicast address and port number. The gmetad host has 5 data_source lines to query one host from each of the 5 clusters. On Mar 23, 2011, at 9:52 AM, Ron Cavallo wrote: > > I need some help.
