==== Request

`PUT _xpack/ml/anomaly_detectors/<job_id>`

//===== Description

==== Path Parameters

`job_id` (required)::
  (string) Identifier for the job


==== Request Body

`analysis_config`::
  (object) The analysis configuration, which specifies how to analyze the data.
  See <<ml-analysisconfig, analysis configuration objects>>.

`analysis_limits`::
  Optionally specifies runtime limits for the job. See <<ml-apilimits,analysis limits>>.

`data_description` (required)::
  (object) Describes the format of the input data. This object is required, but
  it can be empty (`{}`). See <<ml-datadescription,data description objects>>.

`description`::
  (string) An optional description of the job.

`model_snapshot_retention_days`::
  (long) The time in days that model snapshots are retained for the job.
  Older snapshots are deleted. The default value is 1 day.
  For more information about model snapshots, see <<ml-snapshot-resource>>.

`results_index_name`::
  (string) The name of the index in which to store the {ml} results.
  The default value is `shared`, which corresponds to the index name
  `.ml-anomalies-shared`.


==== Authorization

You must have `manage_ml`, or `manage` cluster privileges to use this API.
For more information, see
{xpack-ref}/security-privileges.html[Security Privileges].
//<<privileges-list-cluster>>.

==== Examples

The following example creates the `it-ops-kpi` job:

[source,js]
--------------------------------------------------
PUT _xpack/ml/anomaly_detectors/it-ops-kpi
{
    "description":"First simple job",
    "analysis_config":{
      "bucket_span": "5m",
      "latency": "0ms",
      "detectors":[
        {
          "detector_description": "low_sum(events_per_min)",
          "function":"low_sum",
          "field_name": "events_per_min"
        }
      ]
    },
    "data_description": {
    "time_field":"@timestamp",
    "time_format":"epoch_ms"
    }
}
--------------------------------------------------
// CONSOLE
// TEST[skip:todo]

When the job is created, you receive the following results:
