=== High Availability Across Multiple Elasticsearch Nodes
Kibana can be configured to connect to multiple Elasticsearch nodes in the same cluster. In situations where a node becomes unavailable,
Kibana will transparently connect to an available node and continue operating. Requests to available hosts will be routed in a round robin fashion.
Currently the Console application is limited to connecting to the first node listed.
In kibana.yml:
--------
elasticsearch.hosts:
- http://elasticsearch1:9200
- http://elasticsearch2:9200
--------
Related configurations include `elasticsearch.sniffInterval`, `elasticsearch.sniffOnStart`, and `elasticsearch.sniffOnConnectionFault`.
These can be used to automatically update the list of hosts as a cluster is resized. Parameters can be found on the {kibana-ref}/settings.html[settings page].
