cat datafeeds API

edit

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

Returns configuration and usage information about datafeeds.

Request

edit

GET /_cat/ml/datafeeds/<feed_id>

GET /_cat/ml/datafeeds

Prerequisites

Description

edit

Datafeeds retrieve data from Elasticsearch for analysis by anomaly detection jobs. For more information, see Datafeeds.

This API returns a maximum of 10,000 datafeeds.

Path parameters

edit
<feed_id>
(Optional, string) A numerical character string that uniquely identifies the datafeed. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.

Query parameters

edit
allow_no_datafeeds
(Optional, Boolean) [7.10] Deprecated in 7.10. Use allow_no_match instead.
allow_no_match

(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.

format
(Optional, string) Short version of the HTTP accept header. Valid values include JSON, YAML, etc.
h

(Optional, string) Comma-separated list of column names to display.

If you do not specify which columns to include, the API returns the default columns. If you explicitly specify one or more columns, it returns only the specified columns.

Valid columns are:

assignment_explanation, ae
For started datafeeds only, contains messages relating to the selection of a node.
buckets.count, bc, bucketsCount
(Default) The number of buckets processed.
id
(Default) A numerical character string that uniquely identifies the datafeed. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.
node.address, na, nodeAddress

The network address of the node.

For started datafeeds only, this information pertains to the node upon which the datafeed is started.

node.ephemeral_id, ne, nodeEphemeralId

The ephemeral ID of the node.

For started datafeeds only, this information pertains to the node upon which the datafeed is started.

node.id, ni, nodeId

The unique identifier of the node.

For started datafeeds only, this information pertains to the node upon which the datafeed is started.

node.name, nn, nodeName

The node name.

For started datafeeds only, this information pertains to the node upon which the datafeed is started.

search.bucket_avg, sba, searchBucketAvg
The average search time per bucket, in milliseconds.
search.count, sc, searchCount
(Default) The number of searches run by the datafeed.
search.exp_avg_hour, seah, searchExpAvgHour
The exponential average search time per hour, in milliseconds.
search.time, st, searchTime
The total time the datafeed spent searching, in milliseconds.
state, s

(Default) The status of the datafeed, which can be one of the following values:

  • starting: The datafeed has been requested to start but has not yet started.
  • started: The datafeed is actively receiving data.
  • stopping: The datafeed has been requested to stop gracefully and is completing its final action.
  • stopped: The datafeed is stopped and will not receive data until it is re-started.
