Hello, I have setup a docker swarm network. I have setup a metricbeat per host, at node level. Now I need to fetch data from prometheus exporters accessible through swarm overlay networks and I'm planning to use the hints based auto-discovery option. So metricbeats will need access services accessible through the swarm network only. How should I approach this? One metricsbeat instance per node or one metricsbeat instance running on the swarm manager node?
