I am newer in Grafana and Elastic search world. I have a problem when I use a default grafana´s template for Elastic search.
I could not display any info on graph. I could reach the server and docker image but I could not display any info on dashboard.
So you get no erros? – No. The gear on up right corner runs and runs and not stops to run
What dashboard do you have? – Docker.Dikio.Error
What ES says? – 5
What query do you issue? – No queries
What is the ES response? – No response.
I attached you can see a download a dashboard sample got from Grafana website.
I saw your trick to open developer tool and I got this error for each access this dashboard do on elasticsearch server
XMLHttpRequest cannot load http://<elastic_server_ip>/_msearch. Request header field Content-Type is not allowed by Access-Control-Allow-Headers in preflight response.
