Configure Kibanaedit

The Kibana server reads properties from the kibana.yml file on startup. The location of this file differs depending on how you installed Kibana. For example, if you installed Kibana from an archive distribution (.tar.gz or .zip), by default it is in $KIBANA_HOME/config. By default, with package distributions (Debian or RPM), it is in /etc/kibana. The config directory can be changed via the KBN_PATH_CONF environment variable:

KBN_PATH_CONF=/home/kibana/config ./bin/kibana

The default host and port settings configure Kibana to run on localhost:5601. To change this behavior and allow remote users to connect, 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.

console.enabled:

Toggling this causes the server to regenerate assets on the next startup, which may cause a delay before pages start being served. Set to false to disable Console. Default: true

cpu.cgroup.path.override:

[7.10.0] Deprecated in 7.10.0. This setting will no longer be supported as of 8.0. This setting has been renamed to ops.cGroupOverrides.cpuPath.

cpuacct.cgroup.path.override:

[7.10.0] Deprecated in 7.10.0. This setting will no longer be supported as of 8.0. This setting has been renamed to ops.cGroupOverrides.cpuAcctPath.

csp.rules:

A content-security-policy template that disables certain unnecessary and potentially insecure capabilities in the browser. It is strongly recommended that you keep the default CSP rules that ship with Kibana.

csp.strict:

Blocks Kibana access to any browser that does not enforce even rudimentary CSP rules. In practice, this disables support for older, less safe browsers like Internet Explorer. For more information, refer to Content Security Policy. Default: true

csp.warnLegacyBrowsers:

Shows a warning message after loading Kibana to any browser that does not enforce even rudimentary CSP rules, though Kibana is still accessible. This configuration is effectively ignored when csp.strict is enabled. Default: true

elasticsearch.customHeaders:

Header names and values to send to Elasticsearch. Any custom headers cannot be overwritten by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration. Default: {}

elasticsearch.hosts:

The URLs of the Elasticsearch instances to use for all your queries. All nodes listed here must be on the same cluster. Default: [ "http://localhost:9200" ]

To enable SSL/TLS for outbound connections to Elasticsearch, use the https protocol in this setting.

elasticsearch.logQueries:

[7.12.0] Deprecated in 7.12.0. This setting is no longer used and will be removed in Kibana 8.0. Instead, configure the elasticsearch.query logger.
This is useful for seeing the query DSL generated by applications that currently do not have an inspector, for example Timelion and Monitoring. Default: false

The following example shows a valid elasticsearch.query logger configuration:

logging:
  appenders:
    console_appender:
      type: console
      layout:
        type: pattern
        highlight: true
  root:
    appenders: [default, console_appender]
    level: warn
  loggers:
    - name: elasticsearch.query
      level: debug

elasticsearch.pingTimeout:

Time in milliseconds to wait for Elasticsearch to respond to pings. Default: the value of the elasticsearch.requestTimeout setting

elasticsearch.requestHeadersWhitelist:

List of Kibana client-side headers to send to Elasticsearch. To send no client-side headers, set this value to [] (an empty list). Removing the authorization header from being whitelisted means that you cannot use basic authentication in Kibana. Default: [ 'authorization' ]

elasticsearch.requestTimeout:

Time in milliseconds to wait for responses from the back end or Elasticsearch. This value must be a positive integer. Default: 30000

elasticsearch.shardTimeout:

Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable. Default: 30000

elasticsearch.sniffInterval:

Time in milliseconds between requests to check Elasticsearch for an updated list of nodes. Default: false

elasticsearch.sniffOnStart:

Attempt to find other Elasticsearch nodes on startup. Default: false

elasticsearch.sniffOnConnectionFault:

Update the list of Elasticsearch nodes immediately following a connection fault. Default: false

elasticsearch.ssl.alwaysPresentCertificate:

Controls Kibana behavior in regard to presenting a client certificate when requested by Elasticsearch. This setting applies to all outbound SSL/TLS connections to Elasticsearch, including requests that are proxied for end users. Default: false

When Elasticsearch uses certificates to authenticate end users with a PKI realm and elasticsearch.ssl.alwaysPresentCertificate is true, proxied requests may be executed as the identity that is tied to the Kibana server.

elasticsearch.ssl.certificate: and elasticsearch.ssl.key:

Paths to a PEM-encoded X.509 client certificate and its corresponding private key. These are used by Kibana to authenticate itself when making outbound SSL/TLS connections to Elasticsearch. For this setting to take effect, the xpack.security.http.ssl.client_authentication setting in Elasticsearch must be also be set to "required" or "optional" to request a client certificate from Kibana.

These settings cannot be used in conjunction with elasticsearch.ssl.keystore.path.

elasticsearch.ssl.certificateAuthorities:

Paths to one or more PEM-encoded X.509 certificate authority (CA) certificates, which make up a trusted certificate chain for Elasticsearch. This chain is used by Kibana to establish trust when making outbound SSL/TLS connections to Elasticsearch.

In addition to this setting, trusted certificates may be specified via elasticsearch.ssl.keystore.path and/or elasticsearch.ssl.truststore.path.

elasticsearch.ssl.keyPassphrase:

The password that decrypts the private key that is specified via elasticsearch.ssl.key. This value is optional, as the key may not be encrypted.

elasticsearch.ssl.keystore.path:

Path to a PKCS#12 keystore that contains an X.509 client certificate and it’s corresponding private key. These are used by Kibana to authenticate itself when making outbound SSL/TLS connections to Elasticsearch. For this setting, you must also set the xpack.security.http.ssl.client_authentication setting in Elasticsearch to "required" or "optional" to request a client certificate from Kibana.

If the keystore contains any additional certificates, they are used as a trusted certificate chain for Elasticsearch. This chain is used by Kibana to establish trust when making outbound SSL/TLS connections to Elasticsearch. In addition to this setting, trusted certificates may be specified via elasticsearch.ssl.certificateAuthorities and/or elasticsearch.ssl.truststore.path.

This setting cannot be used in conjunction with elasticsearch.ssl.certificate or elasticsearch.ssl.key.

elasticsearch.ssl.keystore.password:

The password that decrypts the keystore specified via elasticsearch.ssl.keystore.path. If the keystore has no password, leave this as blank. If the keystore has an empty password, set this to "".

elasticsearch.ssl.truststore.path:

Path to a PKCS#12 trust store that contains one or more X.509 certificate authority (CA) certificates, which make up a trusted certificate chain for Elasticsearch. This chain is used by Kibana to establish trust when making outbound SSL/TLS connections to Elasticsearch.

In addition to this setting, trusted certificates may be specified via elasticsearch.ssl.certificateAuthorities and/or elasticsearch.ssl.keystore.path.

elasticsearch.ssl.truststore.password:

The password that decrypts the trust store specified via elasticsearch.ssl.truststore.path. If the trust store has no password, leave this as blank. If the trust store has an empty password, set this to "".

elasticsearch.ssl.verificationMode:

Controls the verification of the server certificate that Kibana receives when making an outbound SSL/TLS connection to Elasticsearch. Valid values are "full", "certificate", and "none". Using "full" performs hostname verification, using "certificate" skips hostname verification, and using "none" skips verification entirely. Default: "full"

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. Kibana users still need to authenticate with Elasticsearch, which is proxied through the Kibana server.

enterpriseSearch.host

The URL of your Enterprise Search instance

interpreter.enableInVisualize

Enables use of interpreter in Visualize. Default: true

kibana.defaultAppId:

[7.9.0] Deprecated in 7.9.0. This setting will be removed in Kibana 8.0. Instead, use the defaultRoute advanced setting.
The default application to load. Default: "home"

kibana.index:

[7.11.0] Deprecated in 7.11.0. This setting will be removed in 8.0. Multitenancy by changing kibana.index will not be supported starting in 8.0. See 8.0 Breaking Changes for more details.
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. If you configure a custom index, the name must be lowercase, and conform to the Elasticsearch index name limitations. Default: ".kibana"

kibana.autocompleteTimeout: logo cloud

Time in milliseconds to wait for autocomplete suggestions from Elasticsearch. This value must be a whole number greater than zero. Default: "1000"

logging.root:

The root logger has a dedicated configuration node since this context name is special and is pre-configured for logging by default.

logging.root.appenders:

A list of logging appenders to forward the root level logger instance to. By default root is configured with the default appender that must be included in the list. This is the configuration that all custom loggers will use unless they’re re-configured explicitly. Additional appenders, if configured, can be included in the list.

logging.root.level: logo cloud

Level at which a log record should be logged. Supported levels are: all, fatal, error, warn, info, debug, trace, off. Levels are ordered from all (highest) to off and a log record will be logged it its level is higher than or equal to the level of its logger, otherwise the log record is ignored. Use this value to change the overall log level. Set to all to log all events, including system usage information and all requests. Set to off to silence all logs. Default: info.

logging.loggers:

Allows you to customize a specific logger instance.

logging.loggers.name:

Specific logger instance.

logging.loggers.level:

Level at which a log record should be shown. Supported levels are: all, fatal, error, warn, info, debug, trace, off.

logging.loggers.appenders:

Specific appender format to apply for a particular logger context.

logging.appenders:

Appenders define how and where log messages are displayed (eg. stdout or console) and stored (eg. file on the disk).

logging.appenders.console:

Appender to use for logging records to stdout. By default, uses the [%date][%level][%logger] %message pattern layout. To use a json, set the layout type to json.

logging.appenders.file:

Allows you to specify a fileName to send log records to on disk. To send all log records to file, add the file appender to root.appenders.

logging.appenders.rolling-file:

Similar to Log4j’s RollingFileAppender, this appender will log into a file and rotate if following a rolling strategy when the configured policy triggers. There are currently two policies supported: size-limit and time-interval.

The size limit policy will perform a rollover when the log file reaches a maximum size. Default 100mb

The time interval policy will rotate the log file every given interval of time. Default 24h

map.includeElasticMapsService: logo cloud

Set to false to disable connections to Elastic Maps Service. When includeElasticMapsService is turned off, only the vector layers configured by map.regionmap and the tile layer configured by map.tilemap.url are available in Maps. Default: true

map.proxyElasticMapsServiceInMaps:

Set to true to proxy all Maps application Elastic Maps Service requests through the Kibana server. Default: false

map.regionmap: logo cloud

Specifies additional vector layers for use in Maps visualizations. Each layer object points to an external vector file that contains a geojson FeatureCollection. The file must use the WGS84 coordinate reference system (ESPG:4326) 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 region map configuration.

map.regionmap:
  includeElasticMapsService: false
  layers:
    - name: "Departments of France"
      url: "http://my.cors.enabled.server.org/france_departements.geojson"
      attribution: "INRAP"

Mandatory. The human readable text that is shown under the Options tab when building the Region Map visualization.

map.regionmap.layers[].fields[].name: logo cloud

Mandatory. This value is used to do an inner-join between the document stored in Elasticsearch and the geojson file. For example, 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.

map.regionmap.layers[].name: logo cloud

Mandatory. A description of the map being provided.

map.regionmap.layers[].url: logo cloud

Mandatory. The location of the geojson file as provided by a webserver.

An array of subdomains used by the tile service. Specify the position of the subdomain the URL with the token {s}.

map.tilemap.url: logo cloud

The URL to the tileservice that Kibana uses to display map tiles in tilemap visualizations. By default, Kibana reads this URL from an external metadata service, but users can 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"

migrations.batchSize:

Defines the number of documents migrated at a time. The higher the value, the faster the Saved Objects migration process performs at the cost of higher memory consumption. If the migration fails due to a circuit_breaking_exception, set a smaller batchSize value. Default: 1000

migrations.enableV2:

[experimental] This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features. . Enables the new Saved Objects migration algorithm. For information about the migration algorithm, refer to Upgrade migrations. When migrations v2 is stable, the setting will be removed in an upcoming release without any further notice. Setting the value to false causes Kibana to use the legacy migration algorithm, which shipped in 7.11 and earlier versions. Default: true

migrations.retryAttempts:

The number of times migrations retry temporary failures, such as a network timeout, 503 status code, or snapshot_in_progress_exception. When upgrade migrations frequently fail after exhausting all retry attempts with a message such as Unable to complete the [...] step after 15 attempts, terminating., increase the setting value.

Override for cgroup cpuacct path when mounted in a manner that is inconsistent with /proc/self/cgroup.

savedObjects.maxImportExportSize:

The maximum count of saved objects that can be imported or exported. This setting exists to prevent the Kibana server from runnning out of memory when handling large numbers of saved objects. It is recommended to only raise this setting if you are confident your server can hold this many objects in memory. Default: 10000

savedObjects.maxImportPayloadBytes:

The maximum byte size of a saved objects import that the Kibana server will accept. This setting exists to prevent the Kibana server from runnning out of memory when handling a large import payload. Note that this setting overrides the more general server.maxPayloadBytes for saved object imports only. Default: 26214400

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 (/).

[experimental] This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features. Set to true to allow browser code to access response body whenever request performed with user credentials. Default: false

server.cors.allowOrigin:

[experimental] This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features. List of origins permitted to access resources. You must specify explicit hostnames and not use server.cors.allowOrigin: ["*"] when server.cors.allowCredentials: true. Default: ["*"]

server.compression.referrerWhitelist:

Specifies an array of trusted hostnames, such as the Kibana host, or a reverse proxy sitting in front of it. This determines whether HTTP compression may be used for responses, based on the request Referer header. This setting may not be used when server.compression.enabled is set to false. Default: none

server.customResponseHeaders: logo cloud

server.rewriteBasePath:

Specifies whether Kibana should rewrite requests that are prefixed with server.basePath or require that they are rewritten by your reverse proxy. In Kibana 6.3 and earlier, the default is false. In Kibana 7.x, the setting is deprecated. In Kibana 8.0 and later, the default is true. Default: deprecated

server.socketTimeout:

The number of milliseconds to wait before closing an inactive socket. Default: "120000"

server.ssl.certificate: and server.ssl.key:
