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

[[ml-get-datafeed-desc]]
|
|
==== {api-description-title}
|
|
|
|
You can get information for multiple {dfeeds} in a single API request by using a
|
|
comma-separated list of {dfeeds} or a wildcard expression. You can get
|
|
information for all {dfeeds} by using `_all`, by specifying `*` as the
|
|
`<feed_id>`, or by omitting the `<feed_id>`.
|
|
|
|
IMPORTANT: This API returns a maximum of 10,000 {dfeeds}.
|
|
|
|
[[ml-get-datafeed-path-parms]]
|
|
==== {api-path-parms-title}
|
|
|
|
`<feed_id>`::
|
|
(Optional, string) Identifier for the {dfeed}. It can be a {dfeed} identifier
|
|
or a wildcard expression. If you do not specify one of these options, the API
|
|
returns information about all {dfeeds}.
|
|
|
|
[[ml-get-datafeed-query-parms]]
|
|
==== {api-query-parms-title}
|
|
|
|
`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.
