    The cluster nodes stats API allows to retrieve one or more (or all) of
    the cluster nodes statistics.

    :arg node_id: A comma-separated list of node IDs or names to limit the
        returned information; use `_local` to return information from the
        node you're connecting to, leave empty to get information from all
        nodes
    :arg metric: Limit the information returned to the specified metrics
    :arg index_metric: Limit the information returned for `indices` metric
        to the specific index metrics. Isn't used if `indices` (or `all`)
        metric isn't specified.
    :arg completion_fields: A comma-separated list of fields for `fielddata`
        and `suggest` index metric (supports wildcards)
    :arg fielddata_fields: A comma-separated list of fields for `fielddata`
        index metric (supports wildcards)
    :arg fields: A comma-separated list of fields for `fielddata` and
        `completion` index metric (supports wildcards)

        metric
    :arg include_segment_file_sizes: Whether to report the aggregated disk
        usage of each one of the Lucene index files (only applies if segment
        stats are requested), default False
    :arg level: Return indices stats aggregated at index, node or shard
        level, default 'node', valid choices are: 'indices', 'node',
        'shards'
    :arg timeout: Explicit operation timeout
    :arg types: A comma-separated list of document types for the `indexing`
        index metric
