Get datafeeds

GET /_cat/ml/datafeeds/{datafeed_id}
GET /_cat/ml/datafeeds

Auth

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 privileges

Cluster privileges monitor_ml

Path parameters

datafeed_id string optional

A numerical character string that uniquely identifies the datafeed.

Leave it out to use /_cat/ml/datafeeds.

Query parameters

allow_no_match boolean · default: true

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 union oneOf · default: id,state,buckets.count,search.count

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.

One of: string[] or string

s union string | string[]

format string · default: text

Specifies the format to return the columnar data in, can be set to text, json, cbor, yaml, or smile.

help boolean · default: false

When set to true will output available columns. This option can't be combined with any other query string option.

v boolean · default: false

When set to true will enable verbose output.

bytes enum

Sets the units for columns that contain a byte-size value. Note that byte-size value units work in terms of powers of 1024. For instance 1kb means 1024 bytes, not 1000 bytes. If omitted, byte-size values are rendered with a suffix such as kb, mb, or gb, chosen such that the numeric value of the column is as small as possible whilst still being at least 1.0. If given, byte-size values are rendered as an integer with no suffix, representing the value of the column in the chosen unit. Values that are not an exact multiple of the chosen unit are rounded down.

Values: b kb mb gb tb pb

time enum

Sets the units for columns that contain a time duration. If omitted, time duration values are rendered with a suffix such as ms, s, m or h, chosen such that the numeric value of the column is as small as possible whilst still being at least 1.0. If given, time duration values are rendered as an integer with no suffix. Values that are not an exact multiple of the chosen unit are rounded down.

Values: nanos micros ms s m h d
