= 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}

Requires the `monitor_ml` cluster privilege. This privilege is included in the 
`machine_learning_user` built-in role.

[[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.
