[[settings]]
== 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. Finally, environment variables can be injected into configuration using `${MY_ENV_VAR}` syntax.
.Kibana Configuration Settings
`console.enabled:`:: *Default: true* Set to false to disable Console. Toggling this will cause the server to regenerate assets on the next startup, which may cause a delay before pages start being served.
`cpu.cgroup.path.override:`:: Override for cgroup cpu path when mounted in manner that is inconsistent with `/proc/self/cgroup`
`cpuacct.cgroup.path.override:`:: Override for cgroup cpuacct path when mounted in manner that is inconsistent with `/proc/self/cgroup`
`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.logQueries:`:: *Default: `false`* Logs queries sent to Elasticsearch. Requires `logging.verbose` set to `true`. This is useful for seeing the query DSL generated by applications that currently do not have a spy panel, for example Timelion and Monitoring.
`elasticsearch.pingTimeout:`:: *Default: the value of the `elasticsearch.requestTimeout` setting* Time in milliseconds to
wait for Elasticsearch to respond to pings.
`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.
`elasticsearch.requestHeadersWhitelist:`:: *Default: `[ 'authorization' ]`* List of Kibana client-side headers to send to Elasticsearch.
To send *no* client-side headers, set this value to [] (an empty list).
`elasticsearch.requestTimeout:`:: *Default: 30000* Time in milliseconds to wait for responses from the back end or
Elasticsearch. This value must be a positive integer.
`elasticsearch.shardTimeout:`:: *Default: 30000* Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable.
`elasticsearch.ssl.certificate:` and `elasticsearch.ssl.key:`:: Optional settings that provide the paths to the PEM-format SSL
certificate and key files. These files are used to verify the identity of Kibana to Elasticsearch and are required when `xpack.ssl.verification_mode` in Elasticsearch is set to either `certificate` or `full`.
`elasticsearch.ssl.certificateAuthorities:`:: Optional setting that enables you to specify a list of paths to the PEM file for the certificate authority for your Elasticsearch instance.
`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.
`elasticsearch.ssl.verificationMode:`:: *Default: full* Controls the verification of certificates presented by Elasticsearch. Valid values are `none`, `certificate`, and `full`.
`full` performs hostname verification, and `certificate` does not.
`elasticsearch.startupTimeout:`:: *Default: 5000* Time in milliseconds to wait for Elasticsearch at Kibana startup before
retrying.
`elasticsearch.url:`:: *Default: "http://localhost:9200"* The URL of the Elasticsearch instance to use for all your
queries.
`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.
`kibana.defaultAppId:`:: *Default: "discover"* The default application to load.
`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.
`logging.dest:`:: *Default: `stdout`* Enables you specify a file where Kibana stores log output.
`logging.quiet:`:: *Default: false* Set the value of this setting to `true` to suppress all logging output other than
error messages.
`logging.silent:`:: *Default: false* Set the value of this setting to `true` to suppress all logging output.
[[logging-verbose]]`logging.verbose:`:: *Default: false* Set the value of this setting to `true` to log all events, including system usage information and all requests. Supported on Elastic Cloud Enterprise.
`logging.useUTC`:: *Default: true* Set the value of this setting to `false` to log events using the timezone of the server, rather than UTC.
`map.includeElasticMapsService:`:: *Default: true* Turns on or off whether layers from the Elastic Maps Service should be included in the vector and tile layer option list.
By turning this off, only the layers that are configured here will be included.
[[regionmap-settings]] `map.regionmap:`:: Specifies additional vector layers for use in <<regionmap, Region Map>> visualizations. Supported on Elastic Cloud Enterprise.
Each layer object points to an external vector file that contains a geojson FeatureCollection.
The file must use the https://en.wikipedia.org/wiki/World_Geodetic_System[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 following example shows a valid regionmap configuration.
map.regionmap:
includeElasticMapsService: false
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"
[[regionmap-name]]`map.regionmap.layers[].name:`:: Mandatory. A description of the map being provided. Supported on Elastic Cloud Enterprise.
[[regionmap-url]]`map.regionmap.layers[].url:`:: Mandatory. The location of the geojson file as provided by a webserver. Supported on Elastic Cloud Enterprise.
[[regionmap-attribution]]`map.regionmap.layers[].attribution:`:: Optional. References the originating source of the geojson file. Supported on Elastic Cloud Enterprise.
[[regionmap-fields]]`map.regionmap.layers[].fields[]:`:: Mandatory. Each layer can contain multiple fields to indicate what properties from the geojson features you wish to expose. The example above shows how to define multiple properties. Supported on Elastic Cloud Enterprise.
[[regionmap-field-name]]`map.regionmap.layers[].fields[].name:`:: Mandatory. This value is used to do an inner-join between the document stored in Elasticsearch and the geojson file. e.g. if the field in the geojson is called `Location` and has city names, there must be a field in Elasticsearch that holds the same values that Kibana can then use to lookup for the geoshape data. Supported on Elastic Cloud Enterprise.
[[regionmap-field-description]]`map.regionmap.layers[].fields[].description:`:: Mandatory. The human readable text that is shown under the Options tab when building the Region Map visualization. Supported on Elastic Cloud Enterprise.
[[regionmap-ES-map]]`map.regionmap.includeElasticMapsService:`:: turns on or off whether layers from the Elastic Maps Service should be included in the vector layer option list. Supported on Elastic Cloud Enterprise.
By turning this off, only the layers that are configured here will be included. The default is true.
[[tilemap-settings]] `map.tilemap.options.attribution:`:: *Default: `"© [Elastic Maps Service](https://www.elastic.co/elastic-maps-service)"`* The map attribution string. Supported on Elastic Cloud Enterprise.
[[tilemap-max-zoom]]`map.tilemap.options.maxZoom:`:: *Default: 10* The maximum zoom level. Supported on Elastic Cloud Enterprise.
[[tilemap-min-zoom]]`map.tilemap.options.minZoom:`:: *Default: 1* The minimum zoom level. Supported on Elastic Cloud Enterprise.
[[tilemap-subdomains]]`map.tilemap.options.subdomains:`:: An array of subdomains used by the tile service.
Specify the position of the subdomain the URL with the token `{s}`. Supported on Elastic Cloud Enterprise.
[[tilemap-url]]`map.tilemap.url:`:: The URL to the tileservice that Kibana uses to display map tiles in tilemap visualizations. Supported on Elastic Cloud Enterprise.
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"`
`server.basePath:`:: Enables you to specify a path to mount Kibana at if you are running behind a proxy. Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath from requests it receives, and to prevent a deprecation warning at startup. This setting cannot end in a slash (`/`).
`path.data:`:: *Default: `data`* The path where Kibana stores persistent data not saved in Elasticsearch.
`pid.file:`:: Specifies the path where Kibana creates the process ID file.
`ops.interval:`:: *Default: 5000* Set the interval in milliseconds to sample system and process performance metrics.
The minimum value is 100.
`server.rewriteBasePath:`:: *Default: false* Specifies whether Kibana should rewrite requests that are prefixed with `server.basePath` or require that they are rewritten by your reverse proxy. This setting was effectively always `false` before Kibana 6.3 and will default to `true` starting in Kibana 7.0.
`server.customResponseHeaders:`:: *Default: `{}`* Header names and values to send on all responses to the client from the Kibana server.

`server.name:`:: *Default: "your-hostname"* A human-readable display name that identifies this Kibana instance.
`server.port:`:: *Default: 5601* Kibana is served by a back end server. This setting specifies the port to use.
`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.certificateAuthorities:`:: List of paths to PEM encoded certificate files that should be trusted.
`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*.
