node_meta only contains mapping for 1 host #130

I have the node-exporter running on 4 nodes (1 manager, 3 workers) but the node_meta query is only returning a mapping for the manager mode. The /etc/hostname is correct for all hosts. Not sure where to start on debugging this issue.

Embarrassingly, turned out to be basic swarm issues. My worker nodes were all physically up, but for some reason had been ejected from the swarm, nothing to do with the stack config for monitoring.
