I dont know what is missing here. When i login to Kibana Dashboard I see below error for plugin:Monitoring in Kibana dashboard Monitoring tab :

ui settings  Ready
plugin:kibana@5.1.2  Ready
plugin:elasticsearch@5.1.2  Kibana index ready

Can you look at the Kibana server log? There might be more details there about what is causing the timeout.
