Get configuration and usage information about datafeeds.
This API returns a maximum of 10,000 datafeeds.
If the Elasticsearch security features are enabled, you must have `monitor_ml`, `monitor`, `manage_ml`, or `manage`
cluster privileges to use this API.

IMPORTANT: CAT APIs are only intended for human consumption using the Kibana
console or command line. They are not intended for use by applications. For
application consumption, use the get datafeed statistics API.

## Required authorization

* Cluster privileges: `monitor_ml`



## Servers
- http://api.example.com: http://api.example.com ()


## Authentication methods
- Api key auth


## Parameters

### Path parameters
- **datafeed_id** (string)
  A numerical character string that uniquely identifies the datafeed.

### Query parameters
- **allow_no_match** (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.

  If `true`, the API returns an empty datafeeds array when there are no matches and the subset of results when
  there are partial matches. If `false`, the API returns a 404 status code when there are no matches or only
  partial matches.
- **h** (string | array[string])
  Comma-separated list of column names to display.

  Supported values include:
    - `ae` (or `assignment_explanation`): For started datafeeds only, contains messages relating to the selection of
  a node.
    - `bc` (or `buckets.count`, `bucketsCount`): The number of buckets processed.
    - `id`: A numerical character string that uniquely identifies the datafeed.
    - `na` (or `node.address`, `nodeAddress`): For started datafeeds only, the network address of the node where the
  datafeed is started.
    - `ne` (or `node.ephemeral_id`, `nodeEphemeralId`): For started datafeeds only, the ephemeral ID of the node where the
  datafeed is started.
    - `ni` (or `node.id`, `nodeId`): For started datafeeds only, the unique identifier of the node where the
  datafeed is started.
    - `nn` (or `node.name`, `nodeName`): For started datafeeds only, the name of the node where the datafeed is
  started.
    - `sba` (or `search.bucket_avg`, `searchBucketAvg`): The average search time per bucket, in milliseconds.
    - `sc` (or `search.count`, `searchCount`): The number of searches run by the datafeed.
    - `seah` (or `search.exp_avg_hour`, `searchExpAvgHour`): The exponential average search time per hour, in milliseconds.
    - `st` (or `search.time`, `searchTime`): The total time the datafeed spent searching, in milliseconds.
    - `s` (or `state`): The status of the datafeed: `starting`, `started`, `stopping`, or `stopped`.
  If `starting`, the datafeed has been requested to start but has not yet
  started. If `started`, the datafeed is actively receiving data. If
  `stopping`, the datafeed has been requested to stop gracefully and is
  completing its final action. If `stopped`, the datafeed is stopped and will
  not receive data until it is re-started.

- **s** (string | array[string])
  Comma-separated list of column names or column aliases used to sort the response.

  Supported values include:
    - `ae` (or `assignment_explanation`): For started datafeeds only, contains messages relating to the selection of
  a node.
    - `bc` (or `buckets.count`, `bucketsCount`): The number of buckets processed.
    - `id`: A numerical character string that uniquely identifies the datafeed.
    - `na` (or `node.address`, `nodeAddress`): For started datafeeds only, the network address of the node where the
  datafeed is started.
    - `ne` (or `node.ephemeral_id`, `nodeEphemeralId`): For started datafeeds only, the ephemeral ID of the node where the
  datafeed is started.
    - `ni` (or `node.id`, `nodeId`): For started datafeeds only, the unique identifier of the node where the
  datafeed is started.
    - `nn` (or `node.name`, `nodeName`): For started datafeeds only, the name of the node where the datafeed is
  started.
    - `sba` (or `search.bucket_avg`, `searchBucketAvg`): The average search time per bucket, in milliseconds.
    - `sc` (or `search.count`, `searchCount`): The number of searches run by the datafeed.
    - `seah` (or `search.exp_avg_hour`, `searchExpAvgHour`): The exponential average search time per hour, in milliseconds.
    - `st` (or `search.time`, `searchTime`): The total time the datafeed spent searching, in milliseconds.
    - `s` (or `state`): The status of the datafeed: `starting`, `started`, `stopping`, or `stopped`.
  If `starting`, the datafeed has been requested to start but has not yet
  started. If `started`, the datafeed is actively receiving data. If
  `stopping`, the datafeed has been requested to stop gracefully and is
