If provided, the link MUST be serialized according to [RFC 8288](https://www.rfc-editor.org/rfc/rfc8288.html#section-3) and MUST use the relation type `monitor`. The link MUST follow the specifications for the links `GET /jobs/{job_id}/logs` and `GET /services/{service_id}/logs`, except that is MUST NOT accept any parameters (limit/offset). Therefore, the link MUST be accessible with HTTP GET, MUST be secured using a Bearer token and MUST follow the corresponding request body schema.
