=== Close {anomaly-jobs} API
|
|
++++
|
|
<titleabbrev>Close jobs</titleabbrev>
|
|
++++
|
|
|
|
Closes one or more {anomaly-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.

[[ml-close-job-prereqs]]
|
|
==== {api-prereq-title}
|
|
|
|
* If the {es} {security-features} are enabled, you must have `manage_ml` or
|
|
`manage` cluster privileges to use this API. See
|
|
<<security-privileges>>.
|
|
* Before you can close an {anomaly-job}, you must stop its {dfeed}. See
|
|
<<ml-stop-datafeed>>.
|
|
|
|
[[ml-close-job-desc]]
|
|
==== {api-description-title}
|
|
|
|
You can close 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 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 {dfeed} that has a specified end date stops, it automatically closes
|
|
the job.
|
|
|
|
NOTE: 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.
|
|
|
|
[[ml-close-job-path-parms]]
|
|
==== {api-path-parms-title}
|
|
|
|
`<job_id>`::
|
|
(Required, string) Identifier for the {anomaly-job}. It can be a job
|
|
identifier, a group name, or a wildcard expression.
|
|
|
|
[[ml-close-job-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.
|
|
--
|
|
|
|
`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, time units>>) Controls the time to wait until a job
|
|
has closed. The default value is 30 minutes.
|
|
|
|
[[ml-close-job-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-close-job-example]]
|
|
==== {api-examples-title}
|
|
|
|
The following example closes the `total-requests` job:
|
|
|
|
[source,console]
|
|
--------------------------------------------------
|
|
POST _ml/anomaly_detectors/total-requests/_close
|
|
--------------------------------------------------
|
|
// TEST[skip:sometimes fails due to https://github.com/elastic/elasticsearch/pull/48583#issuecomment-552991325 - on unmuting use setup:server_metrics_openjob-raw]
|
|
|
|
When the job is closed, you receive the following results:
|
|
|
|

"closed": true
