Fleet settings in Kibana

In Elastic Cloud, Fleet flags are already configured.

You can configure xpack.fleet settings in your kibana.yml. By default, Fleet is enabled. To use Fleet, you also need to configure Kibana and Elasticsearch hosts.

Many Fleet settings can also be configured directly through the Fleet UI. See Fleet UI settings for details.

See the Fleet docs for more information about Fleet.

General Fleet settings

edit

xpack.fleet.agents.enabled: Set to true (default) to enable Fleet.
xpack.fleet.isAirGapped: Set to true to indicate Fleet is running in an air-gapped environment. Refer to Air-gapped environments for details. Enabling this flag helps Fleet skip needless requests and improve the user experience for air-gapped environments.

Elastic Package Manager settings

edit

xpack.fleet.registryUrl: The address to use to reach the Elastic Package Manager registry.
xpack.fleet.registryProxyUrl: The proxy address to use to reach the Elastic Package Manager registry if an internet connection is not directly available. Refer to Air-gapped environments for details.
xpack.fleet.packageVerification.gpgKeyPath: The path on disk to the GPG key used to verify Elastic Package Manager packages. If the Elastic public key is ever reissued as a security precaution, you can use this setting to specify the new key.

Fleet settings

edit

xpack.fleet.agents.fleet_server.hosts

Hostnames used by Elastic Agent for accessing Fleet Server.

If configured in your kibana.yml, this setting is grayed out and unavailable in the Fleet UI. To make this setting editable in the UI, do not configure it in the configuration file.

xpack.fleet.agents.elasticsearch.hosts

Hostnames used by Elastic Agent for accessing Elasticsearch.

xpack.fleet.agents.elasticsearch.ca_sha256

Hash pin used for certificate verification. The pin is a base64-encoded string of the SHA-256 fingerprint.

Preconfiguration settings (for advanced use cases)

edit

Use these settings to pre-define integrations, agent policies, and Fleet Server hosts or proxies that you want Fleet to load up by default.

These settings are not supported to pre-configure the Endpoint and Cloud Security integration.

xpack.fleet.packages

List of integrations that are installed when the Fleet app starts up for the first time.

Required properties of xpack.fleet.packages

ID of the output to send monitoring data. (Need to be identical to data_output_id)

package_policies

List of integration policies to add to this policy.

Properties of package_policies

description

Text string describing this integration policy.

namespace

String identifying this policy’s namespace.

inputs

Map of input for the integration. Follows the same schema as the package policy API inputs, with the exception that any object in vars can be passed frozen: true in order to prevent that specific var from being edited by the user.

Example configuration:

xpack.fleet.packages:
  - name: apache
    version: 0.5.0

xpack.fleet.agentPolicies:
  - name: Preconfigured Policy
    id: preconfigured-policy
    namespace: test
    package_policies:
      - package:
          name: system
        name: System Integration
        namespace: test
        id: preconfigured-system
        inputs:
          system-system/metrics:
            enabled: true
            vars:
              '[system.hostfs]': home/test
            streams:
              '[system.core]':
                enabled: true
                vars:
                  period: 20s
          system-winlog:
            enabled: false

xpack.fleet.outputs

List of outputs that are configured when the Fleet app starts.

Certain types of outputs have additional required and optional settings. Refer to Output settings in the Fleet and Elastic Agent Guide for the full list of settings for each output type.

If configured in your kibana.yml, output settings are grayed out and unavailable in the Fleet UI. To make these settings editable in the UI, do not configure them in the configuration file.

The xpack.fleet.outputs settings are intended for advanced configurations such as having multiple outputs. We recommend not enabling the xpack.fleet.agents.elasticsearch.host settings when using xpack.fleet.outputs.

Required properties of xpack.fleet.outputs

id: Unique ID for this output. The ID should be a string.
name: Output name.
type: Type of Output. Currently we support "elasticsearch", "logstash", "kafka", and "remote_elasticsearch".
hosts: Array that contains the list of host for that output.

Optional properties of xpack.fleet.outputs

is_default

If true, the output specified in xpack.fleet.outputs will be the one used to send agent data unless there is another one configured specifically for the agent policy.

is_default_monitoring

If true, the output specified in xpack.fleet.outputs will be the one used to send agent monitoring data unless there is another one configured specifically for the agent policy.

is_internal

If true, the output specified in xpack.fleet.outputs will not appear in the UI, and can only be managed via kibana.yml or the Fleet API.

config

Extra config for that output.

proxy_id

Unique ID of a proxy to access the output.

ssl

Set to enable authentication using the Secure Sockets Layer (SSL) protocol.

Properties of ssl

certificate: The SSL certificate that Elastic Agents use to authenticate with the output. Include the full contents of the certificate here.

secrets

Include here any values for preconfigured outputs that should be stored as secrets. A secret value is replaced in the kibana.yml settings file with a reference, with the original value stored externally as a secure hash. Note that this type of secret storage requires all configured Fleet Servers to be on version 8.12.0 or later.

Properties of secrets

key:: The private certificate key that Elastic Agents use to authenticate with the output.

Example xpack.fleet.outputs configuration:

xpack.fleet.outputs:
  - id: my-logstash-output-with-a-secret
    name: preconfigured logstash output with a secret
    type:  logstash
    hosts: ["localhost:9999"]
