=== Get {anomaly-job} statistics API
++++
<titleabbrev>Get job statistics</titleabbrev>
++++

Retrieves usage information for {anomaly-jobs}.

[[ml-get-job-stats-request]]
==== {api-request-title}

`GET _ml/anomaly_detectors/<job_id>/_stats`

`GET _ml/anomaly_detectors/<job_id>,<job_id>/_stats` +

`GET _ml/anomaly_detectors/_stats` +

`GET _ml/anomaly_detectors/_all/_stats` 

[[ml-get-job-stats-prereqs]]
==== {api-prereq-title}

* If the {es} {security-features} are enabled, you must have `monitor_ml`,
`monitor`, `manage_ml`, or `manage` cluster privileges to use this API. See
<<security-privileges>>.

[[ml-get-job-stats-desc]]
==== {api-description-title}

You can get statistics for multiple {anomaly-jobs} in a single API request by
using a group name, a comma-separated list of jobs, or a wildcard expression.
You can get statistics for all {anomaly-jobs} by using `_all`, by specifying `*`
as the `<job_id>`, or by omitting the `<job_id>`.

IMPORTANT: This API returns a maximum of 10,000 jobs.

[[ml-get-job-stats-path-parms]]
==== {api-path-parms-title}

`<job_id>`::
  (Optional, string) An identifier for the {anomaly-job}. It can be a
  job identifier, a group name, or a wildcard expression. If you do not specify
  one of these options, the API returns statistics for all {anomaly-jobs}.

[[ml-get-job-stats-query-parms]]
==== {api-query-parms-title}

`allow_no_jobs`::
  (Optional, boolean) Specifies what to do when the request:
+
--
* Contains wildcard expressions and there are no jobs that match.
* Contains the `_all` string or no identifiers and there are no matches.
* Contains wildcard expressions and there are only partial matches.

The default value is `true`, which returns an empty `jobs` array 
when there are no matches and the subset of results when there are partial 
matches. If this parameter is `false`, the request returns a `404` status code
when there are no matches or only partial matches.
--

[[ml-get-job-stats-results]]
==== {api-response-body-title}

The API returns the following information:

`jobs`::
  (array) An array of {anomaly-job} statistics objects.
  For more information, see <<ml-jobstats>>.

[[ml-get-job-stats-response-codes]]
==== {api-response-codes-title}

`404` (Missing resources)::
  If `allow_no_jobs` is `false`, this code indicates that there are no 
  resources that match the request or only partial matches for the request.

[[ml-get-job-stats-example]]
==== {api-examples-title}

The following example gets usage information for the `farequote` job:
