I added a host to an existing cluster, and noticed the total number of CPU cores for the cluster fluctuate, so I tried restarting all the gmond's in the cluster... but that just made most of the CPU's appear to disappear from Ganglia metrics altogether.
I narrowed it down to this: each gmond only reports cpu_num for nodes that restarted after it. If I restart gmond on node1, it reports cpu_num for itself only, even though other gmonds in the cluster are reporting cpu_num for other nodes. If I restart gmond on node2, node1 will now report cpu_num for itself and for node2 ... but node2 has now "forgotten" cpu_num for all other nodes except itself. And so on. It's a catch-22. I can't make them all see every node's metrics.
