== Configuring Kibana

The Kibana server reads properties from the `kibana.yml` file on startup. The default settings configure Kibana to run
on `localhost:5601`. To change the host or port number, or connect to Elasticsearch running on a different machine,
you'll need to update your `kibana.yml` file. You can also enable SSL and set a variety of other options.

.Kibana Configuration Settings
`server.port:`:: *Default: 5601* Kibana is served by a back end server. This setting specifies the port to use.
`server.host:`:: *Default: "localhost"* This setting specifies the host of the back end server.
`server.basePath:`:: Enables you to specify a path to mount Kibana at if you are running behind a proxy. This only affects
 the URLs generated by Kibana, your proxy is expected to remove the basePath value before forwarding requests
 to Kibana. This setting cannot end in a slash (`/`).
`server.maxPayloadBytes:`:: *Default: 1048576* The maximum payload size in bytes for incoming server requests.
`server.name:`:: *Default: "your-hostname"* A human-readable display name that identifies this Kibana instance.
`server.defaultRoute:`:: *Default: "/app/kibana"* This setting specifies the default route when opening Kibana. You can use this setting to modify the landing page when opening Kibana.
`server.customResponseHeaders:`:: *Default: `{}`* Header names and values to send on all responses to the client from the Kibana server.
`elasticsearch.url:`:: *Default: "http://localhost:9200"* The URL of the Elasticsearch instance to use for all your
queries.
`elasticsearch.preserveHost:`:: *Default: true* When this setting’s value is true Kibana uses the hostname specified in
the `server.host` setting. When the value of this setting is `false`, Kibana uses the hostname of the host that connects
to this Kibana instance.
`kibana.index:`:: *Default: ".kibana"* Kibana uses an index in Elasticsearch to store saved searches, visualizations and
dashboards. Kibana creates a new index if the index doesn’t already exist.
`kibana.defaultAppId:`:: *Default: "discover"* The default application to load.
[[tilemap-settings]]`tilemap.url:`:: The URL to the tile
service that Kibana uses to display map tiles in tilemap visualizations. By default, Kibana reads this url from an external metadata service, but users can still override this parameter to use their own Tile Map Service. For example: `"https://tiles.elastic.co/v2/default/{z}/{x}/{y}.png?elastic_tile_service_tos=agree&my_app_name=kibana"`
`tilemap.options.minZoom:`:: *Default: 1* The minimum zoom level.
`tilemap.options.maxZoom:`:: *Default: 10* The maximum zoom level.
`tilemap.options.attribution:`:: *Default: `"© [Elastic Maps Service](https://www.elastic.co/elastic-maps-service)"`* The map attribution string.
`tilemap.options.subdomains:`:: An array of subdomains used by the tile service.
Specify the position of the subdomain the URL with the token `{s}`.

[[regionmap-settings]] `regionmap`:: Specifies additional vector layers for use in <<regionmap, Region Map>> visualizations.
Each layer object points to an external vector file that contains a geojson FeatureCollection.
The file must use the WGS84 coordinate reference system and only include polygons.
If the file is hosted on a separate domain from Kibana, the server needs to be CORS-enabled so Kibana can download the file.
The url field also serves as a unique identifier for the file.
Each layer can contain multiple fields to indicate what properties from the geojson features you want to expose.
The field.description is the human readable text that is shown in the Region Map visualization's field menu.
An optional attribution value can be added as well.
The following example shows a valid regionmap configuration.

    regionmap:
      layers:
         - name: "Departments of France"
           url: "http://my.cors.enabled.server.org/france_departements.geojson"
           attribution: "INRAP"
           fields:
              - name: "department"
                description: "Full department name"
              - name: "INSEE"
                description: "INSEE numeric identifier"

`elasticsearch.username:` and `elasticsearch.password:`:: If your Elasticsearch is protected with basic authentication,
these settings provide the username and password that the Kibana server uses to perform maintenance on the Kibana index at
startup. Your Kibana users still need to authenticate with Elasticsearch, which is proxied through the Kibana server.
`server.ssl.enabled`:: *Default: "false"* Enables SSL for outgoing requests from the Kibana server to the browser. When set to `true`, `server.ssl.certificate` and `server.ssl.key` are required
`server.ssl.certificate:` and `server.ssl.key:`:: Paths to the PEM-format SSL certificate and SSL key files, respectively.
`server.ssl.keyPassphrase`:: The passphrase that will be used to decrypt the private key. This value is optional as the key may not be encrypted.
`server.ssl.redirectHttpFromPort` :: Kibana will bind to this port and redirect all http requests to https over the port configured as `server.port`.
`server.ssl.certificateAuthorities`:: List of paths to PEM encoded certificate files that should be trusted.
`server.ssl.supportedProtocols`:: *Default: TLSv1, TLSv1.1, TLSv1.2*  Supported protocols with versions. Valid protocols: `TLSv1`, `TLSv1.1`, `TLSv1.2`
`server.ssl.cipherSuites`:: *Default: ECDHE-RSA-AES128-GCM-SHA256, ECDHE-ECDSA-AES128-GCM-SHA256, ECDHE-RSA-AES256-GCM-SHA384, ECDHE-ECDSA-AES256-GCM-SHA384, DHE-RSA-AES128-GCM-SHA256, ECDHE-RSA-AES128-SHA256, DHE-RSA-AES128-SHA256, ECDHE-RSA-AES256-SHA384, DHE-RSA-AES256-SHA384, ECDHE-RSA-AES256-SHA256, DHE-RSA-AES256-SHA256, HIGH,!aNULL, !eNULL, !EXPORT, !DES, !RC4, !MD5, !PSK, !SRP, !CAMELLIA*. Details on the format, and the valid options, are available via the [OpenSSL cipher list format documentation](https://www.openssl.org/docs/man1.0.2/apps/ciphers.html#CIPHER-LIST-FORMAT)
`elasticsearch.ssl.certificate:` and `elasticsearch.ssl.key:`:: Optional settings that provide the paths to the PEM-format SSL
certificate and key files. These files validate that your Elasticsearch backend uses the same key files.
`elasticsearch.ssl.keyPassphrase`:: The passphrase that will be used to decrypt the private key. This value is optional as the key may not be encrypted.

To send *no* client-side headers, set this value to [] (an empty list).
`elasticsearch.customHeaders:`:: *Default: `{}`* Header names and values to send to Elasticsearch. Any custom headers
cannot be overwritten by client-side headers, regardless of the `elasticsearch.requestHeadersWhitelist` configuration.
`elasticsearch.shardTimeout:`:: *Default: 0* Time in milliseconds for Elasticsearch to wait for responses from shards. Set
