Use the cat indices API (can be run using curl or from the Kibana console app) to see if there is any data in the cluster and which indices that exist. Please post the full output here.
It does look like you indeed do not have any data in the cluster. You need to sort out the process indexing into Elasticsearch. It seems like you are using fluend, which is not supported here, so you may want to reach out to that community.
