I think there should be 3 hosts here. gstat by default looks at localhost:8649 because it expects gmond to be bound to all interfaces in port 8649. you can use the "-i" option to tell it to poke a different "host" though and therefore the following should work : gstat -a -i ge_node1 or any other of your nodes, as they all have the full cluster report because they are all peers in the multicast setup.
