Close anomaly detection jobs APIedit
Closes one or more anomaly detection jobs. A job can be opened and closed multiple times throughout its lifecycle.
A closed job cannot receive data or perform analysis operations, but you can still explore and navigate results.
Requestedit
POST _ml/anomaly_detectors/<job_id>/_close
POST _ml/anomaly_detectors/<job_id>,<job_id>/_close
POST _ml/anomaly_detectors/_all/_close
Prerequisitesedit
-
If the Elasticsearch security features are enabled, you must have
manage_mlormanagecluster privileges to use this API. See Security privileges. - Before you can close an anomaly detection job, you must stop its datafeed. See Stop datafeeds.
Descriptionedit
You can close multiple anomaly detection jobs in a single API request by using a group
name, a comma-separated list of jobs, or a wildcard expression. You can close
all jobs by using _all or by specifying * as the <job_id>.
When you close a job, it runs housekeeping tasks such as pruning the model history, flushing buffers, calculating final results and persisting the model snapshots. Depending upon the size of the job, it could take several minutes to close and the equivalent time to re-open.
After it is closed, the job has a minimal overhead on the cluster except for maintaining its meta data. Therefore it is a best practice to close jobs that are no longer required to process data.
When a datafeed that has a specified end date stops, it automatically closes the job.
If you use the force query parameter, the request returns without performing
the associated actions such as flushing buffers and persisting the model snapshots.
Therefore, do not use this parameter if you want the job to be in a consistent state
after the close job API returns. The force query parameter should only be used in
situations where the job has already failed, or where you are not interested in
results the job might have recently produced or might produce in the future.
Path parametersedit
-
<job_id> - (Required, string) Identifier for the anomaly detection job. It can be a job identifier, a group name, or a wildcard expression.
Query parametersedit
-
allow_no_jobs -
(Optional, boolean) Specifies what to do when the request:
- Contains wildcard expressions and there are no jobs that match.
-
Contains the
_allstring 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 emptyjobsarray when there are no matches and the subset of results when there are partial matches. If this parameter isfalse, the request returns a404status code when there are no matches or only partial matches. -
force - (Optional, boolean) Use to close a failed job, or to forcefully close a job which has not responded to its initial close request.
-
timeout - (Optional, time units) Controls the time to wait until a job has closed. The default value is 30 minutes.
Response codesedit
-
404(Missing resources) -
If
allow_no_jobsisfalse, this code indicates that there are no resources that match the request or only partial matches for the request.
Examplesedit
POST _ml/anomaly_detectors/low_request_rate/_close
When the job is closed, you receive the following results:
{
"closed": true
}
