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

== {api-description-title}
|
|
|
|
You can get statistics for multiple {dfeeds} in a single API request by using a
|
|
comma-separated list of {dfeeds} or a wildcard expression. You can get
|
|
statistics for all {dfeeds} by using `_all`, by specifying `*` as the
|
|
`<feed_id>`, or by omitting the `<feed_id>`.
|
|
|
|
If the {dfeed} is stopped, the only information you receive is the
|
|
`datafeed_id` and the `state`.
|
|
|
|
IMPORTANT: This API returns a maximum of 10,000 {dfeeds}.
