==== Get Buckets
|
|
|
|
The get bucket API enables you to retrieve job results for one or more buckets.
|
|
|
|
|
|
===== Request
|
|
|
|
`GET _xpack/ml/anomaly_detectors/<job_id>/results/buckets` +
|
|
|
|
`GET _xpack/ml/anomaly_detectors/<job_id>/results/buckets/<timestamp>`
|
|
|
|
|
|
===== Description
|
|
|
|
This API presents a chronological view of the records, grouped by bucket.
|
|
|
|
|
|
===== Path Parameters
|
|
|
|
`job_id`::
|
|
(string) Identifier for the job
|
|
|
|
`timestamp`::
|
|
(string) The timestamp of a single bucket result.
|
|
If you do not specify this optional parameter, the API returns information
|
|
about all buckets.
|
|
|
|
|
|
===== Request Body
|
|
|
|
`anomaly_score`::
|
|
(double) Returns buckets with anomaly scores higher than this value.
|
|
|
|
`desc`::
|
|
(boolean) If true, the buckets are sorted in descending order.
|
|
|
|
`end`::
|
|
(string) Returns buckets with timestamps earlier than this time.
|
|
|
|
`exclude_interim`::
|
|
(boolean) If true, the output excludes interim results.
|
|
By default, interim results are included.
|
|
|
|
`expand`::
|
|
(boolean) If true, the output includes anomaly records.
|
|
|
|
`page`::
|
|
`from`:::
|
|
(integer) Skips the specified number of buckets.
|
|
`size`:::
|
|
(integer) Specifies the maximum number of buckets to obtain.
|
|
|
|
`sort`::
|
|
(string) Specifies the sort field for the requested buckets.
|
|
By default, the buckets are sorted by the `timestamp` field.
|
|
|
|
`start`::
|
|
(string) Returns buckets with timestamps after this time.
|
|
|
|
|
|
===== Results
|
|
|
|
The API returns the following information:
|
|
|
|
`buckets`::
|
|
(array) An array of bucket objects. For more information, see
|
|
<<ml-results-buckets,Buckets>>.
|
|
|
|
|
|
===== Authorization
|
|
|
|
You must have `monitor_ml`, `monitor`, `manage_ml`, or `manage` cluster
|
|
privileges to use this API. You also need `read` index privilege on the index
|
|
that stores the results. The `machine_learning_admin` and `machine_learning_user`
|
|
roles provide these privileges. For more information, see
|
|
<<security-privileges>> and <<built-in-roles>>.
|
|
|
|
|
|
===== Examples
|
|
|
|
The following example gets bucket information for the `it-ops-kpi` job:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET _xpack/ml/anomaly_detectors/it-ops-kpi/results/buckets
|
|
{
|
|
"anomaly_score": 80,
|
|
"start": "1454530200001"
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[skip:todo]
|
|
|
|
In this example, the API returns a single result that matches the specified
|
|
score and time constraints:
