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

csp.rules:

[7.14.0] Deprecated in 7.14.0. In 8.0 and later, this setting will no longer be supported. A Content Security Policy template that disables certain unnecessary and potentially insecure capabilities in the browser.

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

elasticsearch.pingTimeout:

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

elasticsearch.requestHeadersWhitelist:

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.

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.

elasticsearch.ssl.keystore.password:

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.

elasticsearch.serviceAccountToken:

If your Elasticsearch is protected with basic authentication, this token provides the credentials that the Kibana server uses to perform maintenance on the Kibana index at startup. This setting is an alternative to elasticsearch.username and elasticsearch.password.

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 logs to stdout with a pattern layout. This is the configuration that all custom loggers will use unless they’re re-configured explicitly. You can override the default behavior by configuring a different appender to apply to root.

logging.root.level:

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. Default: info.

The following example shows a valid verbose logging.root configuration:

logging.loggers[]:

logging.appenders[]:

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

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 upgrade migrations results in Kibana crashing with an out of memory exception or fails due to an Elasticsearch circuit_breaking_exception, use a smaller batchSize value to reduce the memory pressure. Default: 1000

migrations.maxBatchSizeBytes:

Defines the maximum payload size for indexing batches of upgraded saved objects to avoid migrations failing due to a 413 Request Entity Too Large response from Elasticsearch. This value should be lower than or equal to your Elasticsearch cluster’s http.max_content_length configuration option. Default: 100mb

savedObjects.maxImportExportSize:

The maximum count of saved objects that can be imported or exported. This setting exists to prevent the Kibana server from running 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 running out of memory when handling a large import payload. Note that this setting overrides the more general server.maxPayload 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 (/).

server.xsrf.disableProtection:

Setting this to true will completely disable Cross-site request forgery protection in Kibana. This is not recommended. Default: false

status.allowAnonymous:

If authentication is enabled, setting this to true enables unauthenticated users to access the Kibana server status API and status page. Default: false

telemetry.allowChangingOptInStatus

When true, users are able to change the telemetry setting at a later time in Advanced Settings. When false, Kibana looks at the value of telemetry.optIn to determine whether to send telemetry data or not. telemetry.allowChangingOptInStatus and telemetry.optIn cannot be false at the same time.
