-=== Load Balancing across multiple {es} nodes
-If you have multiple nodes in your Elasticsearch cluster, the easiest way to distribute Kibana requests
-across the nodes is to run an Elasticsearch _Coordinating only_ node on the same machine as Kibana.
-Elasticsearch Coordinating only nodes are essentially smart load balancers that are part of the cluster. They
-process incoming HTTP requests, redirect operations to the other nodes in the cluster as needed, and
-gather and return the results. For more information, see
-{ref}/modules-node.html[Node] in the Elasticsearch reference.
-
-To use a local client node to load balance Kibana requests:
-
-. Install Elasticsearch on the same machine as Kibana.
-. Configure the node as a Coordinating only node. In `elasticsearch.yml`, set `node.data`, `node.master` and `node.ingest` to `false`:
-+
-[source,js]
---------
-# 3. You want this node to be neither master nor data node nor ingest node, but
-#    to act as a "search load balancer" (fetching data from nodes,
-#    aggregating results, etc.)
-#
-node.master: false
-node.data: false
-node.ingest: false
---------
-. Configure the client node to join your Elasticsearch cluster. In `elasticsearch.yml`, set the `cluster.name` to the
-name of your cluster.
-+
-[source,js]
---------
-cluster.name: "my_cluster"
---------
-. Check your transport and HTTP host configs in `elasticsearch.yml` under `network.host` and `transport.host`. The `transport.host` needs to be on the network reachable to the cluster members, the `network.host` is the network for the HTTP connection for Kibana (localhost:9200 by default).
-+
-[source,js]
---------
-network.host: localhost
-http.port: 9200
-
-# by default transport.host refers to network.host
-transport.host: <external ip>
-transport.tcp.port: 9300 - 9400
---------
-. Make sure Kibana is configured to point to your local client node. In `kibana.yml`, the `elasticsearch.hosts` setting should be set to
-`["localhost:9200"]`.

-# The Elasticsearch instance to use for all your queries.
