How do you link elasticsearch to Grafana?

[cypherstream]

Following what was posted in the instructions when creating Elasticsearch datasources in grafana...

How is there no authentication? I just get HTTP 500 Internal server error.

		Name : Elasticsearch-Firewall
		URL : http://192.168.5.211:9200
		Index name : pfelk-firewall*
		Time field name : @timestamp
		Version : 7.0+ (no where on the grafana screen)

If I try to visit the url directly http://192.168.5.211:9200 - I get The connection was reset. I can view all the interesting elasticsearch dashboards by going to http://192.168.5.211:5601 and logging into that web ui. So whats the deal with port 5601 showing pretty graphs and in depth searchable content (it certainly has the data), vs port 9200 which doesn't seem to respond, and thats the port grafana is looking for.
