Kibana is the web UI that sits on top of Elasticsearch.

It does not store anything itself: every panel, every chart, every saved search is built on top of ES queries that Kibana issues live as you interact with it.

You can find the deploy walkthrough for this site in the Kibana setup guide.

The public read-only configuration is in the Kibana viewer-mode page.

Data views

Before you can query data in Kibana, you have to tell it which indices to expose.

A data view is a saved pattern like logs-* or filebeat-* that Kibana resolves at query time.
