cat trained model APIedit

Returns configuration and usage information about inference trained models.

Requestedit

GET /_cat/ml/trained_models

Prerequisitesedit

If the Elasticsearch security features are enabled, you must have the following privileges:

  • cluster: monitor_ml

For more information, see Security privileges and Set up machine learning features.

Query parametersedit

bytes
(Optional, byte size units) Unit used to display byte values.
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:

create_time, ct
The time when the trained model was created.
created_by, c, createdBy
Information on the creator of the trained model.
data_frame_analytics_id, df, dataFrameAnalytics
Identifier for the data frame analytics job that created the model. Only displayed if it is still available.
description, d
The description of the trained model.
heap_size, hs, modelHeapSize
(Default) The estimated heap size to keep the trained model in memory.
id
(Default) Idetifier for the trained model.
ingest.count, ic, ingestCount
The total number of documents that are processed by the model.
ingest.current, icurr, ingestCurrent
The total number of document that are currently being handled by the trained model.
ingest.failed, if, ingestFailed
The total number of failed ingest attempts with the trained model.
ingest.pipelines, ip, ingestPipelines
(Default) The total number of ingest pipelines that are referencing the trained model.
ingest.time, it, ingestTime
The total time that is spent processing documents with the trained model.
license, l
The license level of the trained model.
operations, o, modelOperations
(Default) The estimated number of operations to use the trained model. This number helps measuring the computational complexity of the model.
version, v
The Elasticsearch version number in which the trained model was created.
help
(Optional, boolean) If true, the response includes help information. Defaults to false.
s
(Optional, string) Comma-separated list of column names or column aliases used to sort the response.
time
(Optional, time units) Unit used to display time values.
v
(Optional, boolean) If true, the response includes column headings. Defaults to false.
