Method: Elasticsearch::API::MachineLearning::Actions#get_datafeed_stats

Defined in:
lib/elasticsearch/api/actions/machine_learning/get_datafeed_stats.rb

#get_datafeed_stats(arguments = {}) ⇒ Object

Get datafeed stats. You can get statistics for multiple datafeeds in a single API request by using a comma-separated list of datafeeds or a wildcard expression. You can get statistics for all datafeeds by using _all, by specifying ‘*` as the `<feed_id>`, or by omitting the `<feed_id>`. If the datafeed is stopped, the only information you receive is the datafeed_id and the state. This API returns a maximum of 10,000 datafeeds.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :datafeed_id (String, Array) —

    Identifier for the datafeed. It can be a datafeed identifier or a wildcard expression. If you do not specify one of these options, the API returns information about all datafeeds.

  • :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.

    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.

  • :error_trace (Boolean) —

    When set to true Elasticsearch will include the full stack trace of errors when they occur.

  • :filter_path (String, Array<String>) —

    Comma-separated list of filters in dot notation which reduce the response returned by Elasticsearch.

  • :human (Boolean) —

    When set to true will return statistics in a format suitable for humans. For example ‘“exists_time”: “1h”` for humans and `“exists_time_in_millis”: 3600000` for computers. When disabled the human readable values will be omitted. This makes sense for responses being consumed only by machines.

  • :pretty (Boolean) —

    If set to true the returned JSON will be “pretty-formatted”. Only use this option for debugging only.

  • :headers (Hash) —

    Custom HTTP headers
