Agent Configuration API

edit

The Agent configuration API allows you to fine-tune your APM agent configuration, without needing to redeploy your application.

The following Agent configuration APIs are available:

Create or update configuration to create or update an Agent configuration
Delete configuration to delete an Agent configuration.
List configuration to list all Agent configurations.
Search configuration to search for an Agent configuration.

How to use APM APIs

edit

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 whitelisted using the server.xsrf.whitelist 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.
