APM agent Key APIedit

The APM agent Key API allows you to configure APM agent keys to authorize requests from APM agents to the APM Server.

The following APM agent key APIs are available:

Create agent key to create an APM agent key

How to use APM APIsedit

Expand for required headers, privileges, and usage details

Interact with APM APIs using cURL or another API tool. All APM APIs are Kibana APIs, not Elasticsearch APIs; because of this, the Kibana dev tools console cannot be used to interact with APM APIs.

For all APM APIs, you must use a request header. Supported headers are Authorization, kbn-xsrf, and Content-Type.

Authorization: ApiKey {credentials}

Kibana supports token-based authentication with the Elasticsearch API key service. The API key returned by the Elasticsearch create API key API can be used by sending a request with an Authorization header that has a value of ApiKey followed by the {credentials}, where {credentials} is the base64 encoding of id and api_key joined by a colon.

Alternatively, you can create a user and use their username and password to authenticate API access: -u $USER:$PASSWORD.

Whether using Authorization: ApiKey {credentials}, or -u $USER:$PASSWORD, users interacting with APM APIs must have sufficient privileges.

kbn-xsrf: true

By default, you must use kbn-xsrf for all API calls, except in the following scenarios:

The API endpoint uses the GET or HEAD operations
The path is allowed using the server.xsrf.allowlist setting
XSRF protections are disabled using the server.xsrf.disableProtection setting

Content-Type: application/json

Applicable only when you send a payload in the API request. Kibana API requests and responses use JSON. Typically, if you include the kbn-xsrf header, you must also include the Content-Type header.

Create agent keyedit

Create an APM agent API key. Specify API key privileges in the request body at creation time.

Privilegesedit

The user creating an APM agent API key must have at least the manage_own_api_key cluster privilege and the APM application-level privileges that it wishes to grant.

Example roleedit

The example below uses the Kibana role management API to create a role named apm_agent_key_user. Create and assign this role to a user that wishes to create APM agent API keys.

POST /_security/role/apm_agent_key_user
{
  "cluster": ["manage_own_api_key"],
  "applications": [{
    "application": "apm",
    "privileges": ["event:write", "config_agent:read"],
    "resources": ["*"]
  }]
}

Requestedit

POST /api/apm/agent_keys

Request bodyedit

name

(required, string) Name of the APM agent key.

privileges

(required, array) APM agent key privileges. It can take one or more of the following values:

event:write. Required for ingesting APM agent events.
config_agent:read. Required for APM agents to read agent configuration remotely.

Exampleedit

POST /api/apm/agent_keys
{
    "name": "apm-key",
    "privileges": ["event:write", "config_agent:read"]
}

Response bodyedit

{
  "agentKey": {
    "id": "3DCLmn0B3ZMhLUa7WBG9",
    "name": "apm-key",
    "api_key": "PjGloCGOTzaZr8ilUPvkjA",
    "encoded": "M0RDTG1uMEIzWk1oTFVhN1dCRzk6UGpHbG9DR09UemFacjhpbFVQdmtqQQ=="
  }
}

Once created, you can copy the API key (Base64 encoded) and use it to to authorize requests from APM agents to the APM Server.
