# Get index statistics.
# For data streams, the API retrieves statistics for the stream's backing indices.
# By default, the returned statistics are index-level with `primaries` and `total` aggregations.
# `primaries` are the values for only the primary shards.
# `total` are the accumulated values for both primary and replica shards.
# To get shard-level statistics, set the `level` parameter to `shards`.
# NOTE: When moving to another node, the shard-level statistics for a shard are cleared.
# Although the shard is no longer part of the node, that node retains any node-level statistics to which the shard contributed.
#
# @option arguments [String, Array<String>] :metric Limit the information returned the specific metrics.
# @option arguments [String, Array] :index A comma-separated list of index names; use `_all` or empty string to perform the operation on all indices
# @option arguments [String, Array<String>] :completion_fields Comma-separated list or wildcard expressions of fields to include in fielddata and suggest statistics.
# @option arguments [String, Array<String>] :expand_wildcards Type of index that wildcard patterns can match. If the request can target data streams, this argument
# determines whether wildcard expressions match hidden data streams. Supports comma-separated values,
# such as `open,hidden`.
# @option arguments [String, Array<String>] :fielddata_fields Comma-separated list or wildcard expressions of fields to include in fielddata statistics.
# @option arguments [String, Array<String>] :fields Comma-separated list or wildcard expressions of fields to include in the statistics.
# @option arguments [Boolean] :forbid_closed_indices If true, statistics are not collected from closed indices. Server default: true.
# @option arguments [String] :groups Comma-separated list of search groups to include in the search statistics.
# @option arguments [Boolean] :include_segment_file_sizes If true, the call reports the aggregated disk usage of each one of the Lucene index files (only applies if segment stats are requested).
# @option arguments [Boolean] :include_unloaded_segments If true, the response includes information from segments that are not loaded into memory.
# @option arguments [String] :level Indicates whether statistics are aggregated at the cluster, index, or shard level.
# @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
# when they occur.
# @option arguments [String] :filter_path Comma-separated list of filters in dot notation which reduce the response
# returned by Elasticsearch.
# @option arguments [Boolean] :human When set to `true` will return statistics in a format suitable for humans.
# For example `"exists_time": "1h"` for humans and
# `"eixsts_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.
# @option arguments [Boolean] :pretty If set to `true` the returned JSON will be "pretty-formatted". Only use
# this option for debugging only.
# @option arguments [Hash] :headers Custom HTTP headers
#
# @see https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-stats
