Stop datafeeds APIedit

Stops one or more datafeeds.

Requestedit

POST _ml/datafeeds/<feed_id>/_stop

POST _ml/datafeeds/<feed_id>,<feed_id>/_stop

POST _ml/datafeeds/_all/_stop

Prerequisitesedit

  • If the Elasticsearch security features are enabled, you must have manage_ml or manage cluster privileges to use this API. See Security privileges.

Descriptionedit

A datafeed that is stopped ceases to retrieve data from Elasticsearch. A datafeed can be started and stopped multiple times throughout its lifecycle.

You can stop multiple datafeeds in a single API request by using a comma-separated list of datafeeds or a wildcard expression. You can close all datafeeds by using _all or by specifying * as the <feed_id>.

Path parametersedit

<feed_id>
(Required, string) Identifier for the datafeed. It can be a datafeed identifier or a wildcard expression.

Query parametersedit

allow_no_datafeeds

(Optional, boolean) Specifies what to do when the request:

  • Contains wildcard expressions and there are no datafeeds 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 datafeeds 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.

Request bodyedit

force
(Optional, boolean) If true, the datafeed is stopped forcefully.
timeout
(Optional, time) Controls the amount of time to wait until a datafeed stops. The default value is 20 seconds.

Response codesedit

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

Examplesedit

POST _ml/datafeeds/datafeed-total-requests/_stop
{
  "timeout": "30s"
}

When the datafeed stops, you receive the following results:

{
  "stopped": true
}
