I have a cluster grid node running gmetad that collects data from several cluster. For each cluster I have a leader node that collects stats for its cluster nodes or compute nodes. The grid node cannot directly talk to compute nodes. On the leader node I gather customized metrics about compute nodes and feed them via gmetric into the Ganglia stream. At that point I need to tag the metrics with the originating host's IP addr; a compute node. So, the leader node inject metrics into Ganglia on behalf of compute nodes. For that I obviously need to spoof the IP address from the compute nodes so that metric injected by the leader appear to originate from those nodes.
