Open Jobs API

This API enables you to open one or more jobs. A job must be opened in order for it to be ready to receive and analyze data. A job can be opened and closed multiple times throughout its lifecycle.


POST _xpack/ml/anomaly_detectors/{job_id}/_open


When you open a new job, it starts with an empty model.

When you open an existing job, the most recent model state is automatically loaded. The job is ready to resume its analysis from where it left off, once new data is received.

Path Parameters

job_id (required)
(string) Identifier for the job

Request Body

(time) Controls the time to wait until a job has opened. The default value is 30 minutes.


You must have manage_ml, or manage cluster privileges to use this API. For more information, see Security Privileges.
