ECH Self-Managed

Note

If a setting is applicable to Elastic Cloud Hosted environments, its name is followed by this icon: logo cloud

console.ui.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
csp.script_src
Add sources for the Content Security Policy script-src directive.
csp.disableUnsafeEval

Deprecated in 8.7.0. Use csp.script_src: ['unsafe-eval'] instead if you wish to enable unsafe-eval. This config option will have no effect in a future version. Set this to false to add the unsafe-eval source expression to the script-src directive. Default: true

When csp.disableUnsafeEval is set to true, Kibana will use a custom version of the Handlebars template library. Handlebars is used in various locations in the Kibana frontend where custom templates can be supplied by the user when for instance setting up a visualisation. If you experience any issues rendering Handlebars templates, please set this setting to false and open an issue in the Kibana GitHub repository.

csp.worker_src
Add sources for the Content Security Policy worker-src directive.
csp.style_src
Add sources for the Content Security Policy style-src directive.
csp.connect_src
Add sources for the Content Security Policy connect-src directive.
csp.default_src
Add sources for the Content Security Policy default-src directive.
csp.font_src
Add sources for the Content Security Policy font-src directive.
csp.frame_src
Add sources for the Content Security Policy frame-src directive.
csp.img_src
Add sources for the Content Security Policy img-src directive.
csp.frame_ancestors

Add sources for the Content Security Policy frame-ancestors directive.

Note

The frame-ancestors directive can also be configured by using server.securityResponseHeaders.disableEmbedding. In that case, that takes precedence and any values in csp.frame_ancestors are ignored.

csp.report_only.form_action
Add sources for the Content Security Policy form-action directive in reporting mode.
csp.report_only.object_src
Add sources for the Content Security Policy object-src directive in reporting mode.
csp.report_uri
Add sources for the Content Security Policy report-uri directive.
csp.report_to:
Add sources for the Content Security Policy report-to directive.
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.
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
data.autocomplete.valueSuggestions.terminateAfter logo cloud

Specifies the max number of documents loaded by each shard to generate autocomplete suggestions. The default is 100000. Allowed values are between 1 and 10000000.

data.autocomplete.valueSuggestions.timeout logo cloud

Specifies the time in milliseconds to wait for autocomplete suggestions from Elasticsearch. The default is 1000. Allowed values are between 1 and 1200000.

elasticsearch.maxSockets logo cloud
The maximum number of sockets that can be used for communications with Elasticsearch. Default: Infinity It is available in Elastic Cloud 8.2.0 and later versions.
elasticsearch.maxResponseSize
Either false or a byteSize value. When set, responses from Elasticsearch with a size higher than the defined limit will be rejected. This is intended to be used as a circuit-breaker mechanism to avoid memory errors in case of unexpectedly high responses coming from Elasticsearch. Default: false
elasticsearch.maxIdleSockets
The maximum number of idle sockets to keep open between Kibana and Elasticsearch. If more sockets become idle, they will be closed. Default: 256
elasticsearch.idleSocketTimeout
The timeout for idle sockets kept open between Kibana and Elasticsearch. If the socket is idle for longer than this timeout, it will be closed. If you have a transparent proxy between Kibana and Elasticsearch be sure to set this value lower than or equal to the proxy’s timeout. Default: 60s
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.publicBaseUrl:
The URL through which Elasticsearch is publicly accessible, if any. This will be shown to users in Kibana when they need connection details for your Elasticsearch cluster.
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', 'es-client-authentication' ]
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.compression logo cloud
Specifies whether Kibana should use compression for communications with Elasticsearch. Default: false It is available in Elastic Cloud 8.3.0 and later versions.
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

Warning

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.

Note

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.

Note

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.
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.
execution_context.enabled logo cloud

Propagate request-specific metadata to Elasticsearch server by way of the x-opaque-id header. It is available in Elastic Cloud 8.1.0 and later versions.

logging.root
The root logger has is a dedicated logger and is pre-configured. The root logger logs at info level by default. If any other logging configuration is specified, root must also be explicitly configured.
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 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. Default: info.

Tip

Set to all to log all events, including system usage information and all requests. Set to off to silence all logs. You can also use the logging cli commands to set log level to verbose or silence all logs.

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

logging:
  appenders:
    console_appender:
      type: console
      layout:
        type: pattern
        highlight: true
  root:
    appenders: [console_appender]
    level: all
logging.loggers[]
Allows you to customize a specific logger instance.
logging.appenders[]
Appenders define how and where log messages are displayed (eg. stdout or console) and stored (eg. file on the disk).
map.includeElasticMapsService logo cloud
Set to false to disable connections to Elastic Maps Service. When includeElasticMapsService is turned off, only tile layer configured by map.tilemap.url is available in Maps. Default: true
map.emsUrl
Specifies the URL of a self hosted Elastic Maps Server
map.tilemap.options.attribution logo cloud
The map attribution string. Provide attributions in markdown and use \| to delimit attributions, for example: "[attribution 1](https://www.attribution1)\|[attribution 2](https://www.attribution2)". Default: "© [Elastic Maps Service](https://www.elastic.co/elastic-maps-service)"

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 service that Kibana uses as the default basemap in maps and vega maps. By default, Kibana sets a basemap from the Elastic Maps Service, but users can point to 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 logo cloud
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.discardUnknownObjects logo cloud

Discard saved objects with unknown types during a migration. Must be set to the target version, for example: 8.4.0. Default: undefined. It is available in Elastic Cloud 8.4.0 and later versions.

migrations.discardCorruptObjects logo cloud

Discard corrupt saved objects, as well as those that cause transform errors during a migration. Must be set to the target version, for example: 8.4.0. Default: undefined. It is available in Elastic Cloud 8.4.0 and later versions.

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
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. Default: 15
migrations.useCumulativeLogger Stack 9.2.0
Skip logging migration progress unless there are any errors. Set to false when troubleshooting migration issues and not automatically shown. Default: true
newsfeed.enabled
Controls whether to enable the newsfeed system for the Kibana UI notification center. Set to false to disable the newsfeed system. Default: true
node.roles
Indicates which roles to configure the Kibana process with, which will effectively run Kibana in different modes. Valid options are background_tasks and ui, or * to select all roles. Default: *. This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
notifications.connectors.default.email
Choose the default email connector for user notifications. As of 8.6.0, Kibana is shipping with a new notification mechanism that will send email notifications for various user actions, e.g. assigning a Case to a user. To enable notifications, an email connector must be preconfigured in the system via kibana.yml, and the notifications plugin must be configured to point to the ID of that connector.
ops.interval
Set the interval in milliseconds to sample system and process performance metrics. The minimum value is 100. Default: 5000
ops.cGroupOverrides.cpuPath
Override for cgroup cpu path when mounted in a manner that is inconsistent with /proc/self/cgroup.

The path where Kibana stores persistent data not saved in Elasticsearch. Default: data
permissionsPolicy.report_to:
Add sources for the Permissions Policy report-to directive.
pid.file
Specifies the path where Kibana creates the process ID file.
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.defaultRoute logo cloud

Specifies the default route when opening Kibana. You can use this setting to modify the landing page when opening Kibana.

server.publicBaseUrl
The publicly available URL that end-users access Kibana at. Must include the protocol, hostname, port (if different than the defaults for http and https, 80 and 443 respectively), and the server.basePath (when that setting is configured explicitly). This setting cannot end in a slash (/).
server.compression.enabled
Set to false to disable HTTP compression for all responses. Default: true
server.cors.enabled
Set to true to allow cross-origin API calls. Default: false. This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
server.cors.allowCredentials
Set to true to allow browser code to access response body whenever request performed with user credentials. Default: false. This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
server.cors.allowOrigin Stack Preview
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.compression.brotli.enabled logo cloud

Set to true to enable brotli (br) compression format.

Note

Browsers not supporting brotli compression will fallback to using gzip instead. This setting may not be used when server.compression.enabled is set to false. Default: false

Note

It is available in Elastic Cloud 8.6.0 and later versions.

server.securityResponseHeaders.strictTransportSecurity logo cloud
Controls whether the Strict-Transport-Security header is used in all responses to the client from the Kibana server, and specifies what value is used. Allowed values are any text value or null. To disable, set to null. Default: null
server.securityResponseHeaders.xContentTypeOptions logo cloud
Controls whether the X-Content-Type-Options header is used in all responses to the client from the Kibana server, and specifies what value is used. Allowed values are nosniff or null. To disable, set to null. Default: "nosniff"
server.securityResponseHeaders.referrerPolicy logo cloud
Controls whether the Referrer-Policy header is used in all responses to the client from the Kibana server, and specifies what value is used. Allowed values are no-referrer, no-referrer-when-downgrade, origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url, or null. To disable, set to null. Default: "strict-origin-when-cross-origin"
server.securityResponseHeaders.permissionsPolicy logo cloud
Controls whether the Permissions-Policy header is used in all responses to the client from the Kibana server, and specifies what value is used. Allowed values are any text value or null. Refer to the Permissions-Policy documentation for defined directives, values, and text format. To disable, set to null. Default: camera=(), display-capture=(), fullscreen=(self), geolocation=(), microphone=(), web-share=(). This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
server.securityResponseHeaders.permissionsPolicyReportOnly logo cloud
Controls whether the Permissions-Policy-Report-Only header is used in all responses to the client from the Kibana server, and specifies what value is used. Allowed values are any text value or null. Refer to the Permissions-Policy documentation for defined directives, values, and text format. This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
server.securityResponseHeaders.disableEmbedding logo cloud
Controls whether the Content-Security-Policy and X-Frame-Options headers are configured to disable embedding Kibana in other webpages using iframes. When set to true, secure headers are used to disable embedding, which adds the frame-ancestors: 'self' directive to the Content-Security-Policy response header and adds the X-Frame-Options: SAMEORIGIN response header. Default: false
server.securityResponseHeaders.crossOriginOpenerPolicy logo cloud
Controls whether the Cross-Origin-Opener-Policy header is used in all responses to the client from the Kibana server, and specifies what value is used. Allowed values are unsafe-none, same-origin-allow-popups, same-origin, or null. To disable, set to null. Default: "same-origin" It is available in Elastic Cloud 8.7.0 and later versions.
server.customResponseHeaders logo cloud
Header names and values to send on all responses to the client from the Kibana server. Default: {}
server.shutdownTimeout
Sets the grace period for Kibana to attempt to resolve any ongoing HTTP requests after receiving a SIGTERM/SIGINT signal, and before shutting down. Any new HTTP requests received during this period are rejected, because the incoming socket is closed without further processing. Default: 30s
server.host
This setting specifies the host of the back end server. To allow remote users to connect, set the value to the IP address or DNS name of the Kibana server. Use 0.0.0.0 to make Kibana listen on all IPs (public and private). Default: "localhost"
server.keepaliveTimeout
The number of milliseconds to wait for additional data before restarting the server.socketTimeout counter. Default: "120000"
server.maxPayload logo cloud
The maximum payload size in bytes for incoming server requests. Default: 1048576
server.name
A human-readable display name that identifies this Kibana instance. Default: "your-hostname"
server.port
Kibana is served by a back end server. This setting specifies the port to use. Default: 5601
server.protocol

The HTTP protocol to use, either http1 or http2. Set to http1 to opt out of HTTP/2 support when TLS is enabled. Use of http1 may impact browser loading performance especially for dashboards with many panels. Default: http2 if TLS is enabled, otherwise http1. This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

Note

By default, enabling http2 requires a valid h2c configuration, meaning that TLS must be enabled via server.ssl.enabled and server.ssl.supportedProtocols, if specified, must contain at least TLSv1.2 or TLSv1.3. Strict validation of the h2c setup can be disabled by adding server.http2.allowUnsecure: true to the configuration.

server.rateLimiter.enabled

Enables rate-limiting of requests to the Kibana server based on Node.js' Event Loop Utilization. If the average event loop utilization for the specified term exceeds the configured threshold, the server will respond with a 429 Too Many Requests status code.

This functionality should be used carefully as it may impact the server’s availability. The configuration options vary per environment, so it is recommended to enable this option in a testing environment first, adjust the rate-limiter configuration, and then roll it out to production.

Default: false

server.rateLimiter.elu

The Event Loop Utilization (ELU) threshold for rate-limiting requests to the Kibana server. The ELU is a value between 0 and 1, representing the average event loop utilization over the specified term. If the average ELU exceeds this threshold, the server will respond with a 429 Too Many Requests status code.

In a multi-instance environment with autoscaling, this value is usually between 0.6 and 0.8 to give the autoscaler enough time to react. This value can be higher in a single-instance environment but should not exceed 1.0. In general, the lower the value, the more aggressive the rate limiting. And the highest possible option should be used to prevent the Kibana server from being terminated.

server.rateLimiter.term

This value is one of short, medium, or long, representing the term over which the average event loop utilization is calculated. It uses exponential moving averages (EMA) to smooth out the utilization values. Each term corresponds to 15s, 30s, and 60s, respectively.

The term value also changes the way the rate limiter sees the trend in the load:

  • short: elu.short > server.rateLimiter.term;
  • medium: elu.short > server.rateLimiter.elu AND elu.medium > server.rateLimiter.elu;
  • long: elu.short > server.rateLimiter.elu AND elu.medium > server.rateLimiter.elu AND elu.long > server.rateLimiter.elu.

This behavior prevents requests from being throttled if the load starts decreasing. In general, the shorter the term, the more aggressive the rate limiting. In the multi-instance environment, the medium term makes the most sense as it gives the Kibana server enough time to spin up a new instance and prevents the existing instances from being terminated.

server.requestId.allowFromAnyIp
Sets whether or not the X-Opaque-Id header should be trusted from any IP address for identifying requests in logs and forwarded to Elasticsearch.
server.requestId.ipAllowlist
A list of IPv4 and IPv6 address which the X-Opaque-Id header should be trusted from. Normally this would be set to the IP addresses of the load balancers or reverse-proxy that end users use to access Kibana. If any are set, server.requestId.allowFromAnyIp must also be set to false.
server.rewriteBasePath
Specifies whether Kibana should rewrite requests that are prefixed with server.basePath or require that they are rewritten by your reverse proxy. Default: false
server.socketTimeout
The number of milliseconds to wait before closing an inactive socket. Default: "120000"
server.payloadTimeout
Sets the maximum time allowed for the client to transmit the request payload (body) before giving up and responding with a Request Timeout (408) error response. Default: "20000"
server.ssl.certificate and server.ssl.key

Paths to a PEM-encoded X.509 server certificate and its corresponding private key. These are used by Kibana to establish trust when receiving inbound SSL/TLS connections from users.

Note

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

server.ssl.certificateAuthorities

Paths to one or more PEM-encoded X.509 certificate authority (CA) certificates which make up a trusted certificate chain for Kibana. This chain is used by Kibana to establish trust when receiving inbound SSL/TLS connections from end users. If PKI authentication is enabled, this chain is also used by Kibana to verify client certificates from end users.

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

server.ssl.cipherSuites
Details on the format, and the valid options, are available via the OpenSSL cipher list format documentation. Default: TLS_AES_256_GCM_SHA384 TLS_CHACHA20_POLY1305_SHA256 TLS_AES_128_GCM_SHA256 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.
server.ssl.clientAuthentication
Controls the behavior in Kibana for requesting a certificate from client connections. Valid values are "required", "optional", and "none". Using "required" will refuse to establish the connection unless a client presents a certificate, using "optional" will allow a client to present a certificate if it has one, and using "none" will prevent a client from presenting a certificate. Default: "none"
server.ssl.enabled
| Enables SSL/TLS for inbound connections to Kibana. When set to true, a certificate and its corresponding private key must be provided. These can be specified via server.ssl.keystore.path or the combination of server.ssl.certificate and server.ssl.key. Default: false
server.ssl.keyPassphrase
The password that decrypts the private key that is specified via server.ssl.key. This value is optional, as the key may not be encrypted.
server.ssl.keystore.path

Path to a PKCS#12 keystore that contains an X.509 server certificate and its corresponding private key. If the keystore contains any additional certificates, those will be used as a trusted certificate chain for Kibana. All of these are used by Kibana to establish trust when receiving inbound SSL/TLS connections from end users. The certificate chain is also used by Kibana to verify client certificates from end users when PKI authentication is enabled.

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

Note

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

server.ssl.keystore.password
The password that will be used to decrypt the keystore specified via server.ssl.keystore.path. If the keystore has no password, leave this unset. If the keystore has an empty password, set this to "".
server.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 Kibana. This chain is used by Kibana to establish trust when receiving inbound SSL/TLS connections from end users. If PKI authentication is enabled, this chain is also used by Kibana to verify client certificates from end users.

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

server.ssl.truststore.password
The password that will be used to decrypt the trust store specified via server.ssl.truststore.path. If the trust store has no password, leave this unset. If the trust store has an empty password, set this to "".
server.ssl.redirectHttpFromPort
Kibana binds to this port and redirects all http requests to https over the port configured as server.port.
server.ssl.supportedProtocols
An array of supported protocols with versions. Valid protocols: TLSv1, TLSv1.1, TLSv1.2, TLSv1.3. Default: TLSv1.2, TLSv1.3 Enabling TLSv1.1 would require both setting the --tls-min-1.1 option in the node.options configuration and adding TLSv1.1 to server.ssl.supportedProtocols. HTTP/2 requires the use of minimum TLSv1.2 for secure connections.
server.uuid

server.xsrf.allowlist logo cloud

It is not recommended to disable protections for arbitrary API endpoints. Instead, supply the kbn-xsrf header. The server.xsrf.allowlist setting requires the following format:

*Default: [ ]* An array of API endpoints which should be exempt from Cross-Site Request Forgery ("XSRF") protections.

It is available in Elastic Cloud 8.0.0 and later versions.

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 false, users cannot change the opt-in status through Advanced Settings, and Kibana only looks at the value of telemetry.optIn to determine whether to send telemetry data or not. Default: true.
telemetry.optIn

Set to false to stop sending any telemetry data to Elastic. Reporting your cluster statistics helps us improve your user experience. When false, the telemetry data is never sent to Elastic.

This setting can be changed at any time in Advanced Settings. To prevent users from changing it, set telemetry.allowChangingOptInStatus to false. Default: true

unifiedSearch.autocomplete.valueSuggestions.timeout logo cloud
