Use Kibana in a production environmentedit

How you deploy Kibana largely depends on your use case. If you are the only user, you can run Kibana on your local machine and configure it to point to whatever Elasticsearch instance you want to interact with. Conversely, if you have a large number of heavy Kibana users, you might need to load balance across multiple Kibana instances that are all connected to the same Elasticsearch instance.

While Kibana isn’t terribly resource intensive, we still recommend running Kibana separate from your Elasticsearch data or master nodes. To distribute Kibana traffic across the nodes in your Elasticsearch cluster, you can configure Kibana to use a list of Elasticsearch hosts.

Kibana does not support rolling upgrades, and deploying mixed versions of Kibana can result in data loss or upgrade failures. Please shut down all instances of Kibana before performing an upgrade, and ensure all running Kibana instances have matching versions.

Load balancing across multiple Kibana instancesedit

To serve multiple Kibana installations behind a load balancer, you must change the configuration. See Configuring Kibana for details on each setting.

Settings unique across each Kibana instance:


Settings unique across each host (for example, running multiple installations on the same virtual machine):


Settings that must be the same: //decrypting session information
xpack.reporting.encryptionKey //decrypting reports
xpack.encryptedSavedObjects.encryptionKey // decrypting saved objects
xpack.encryptedSavedObjects.keyRotation.decryptionOnlyKeys // saved objects encryption key rotation, if any

Separate configuration files can be used from the command line by using the -c flag:

bin/kibana -c config/instance1.yml
bin/kibana -c config/instance2.yml

Accessing multiple load-balanced Kibana clustersedit

To access multiple load-balanced Kibana clusters from the same browser, explicitly set to the same value in the Kibana configuration of each Kibana instance.

Each Kibana cluster must have a different value of

This avoids conflicts between cookies from the different Kibana instances.

This will achieve seamless high availability and keep the session active in case of failure from the currently used instance.

High availability across multiple Elasticsearch nodesedit

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.

In kibana.yml:

  - 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 settings page.


Kibana has a default memory limit that scales based on total memory available. In some scenarios, such as large reporting jobs, it may make sense to tweak limits to meet more specific requirements.

A limit can be defined by setting --max-old-space-size in the node.options config file found inside the kibana/config folder or any other folder configured with the environment variable KBN_PATH_CONF. For example, in the Debian-based system, the folder is /etc/kibana.

The option accepts a limit in MB:
