   *     and send back in response. These metrics will be retrieved
   *     irrespective of whether metrics are specified in fields to retrieve or
   *     not.

   *     {@link Field}. All fields will be retrieved if fields=ALL. If not
   *     specified, 3 fields i.e. entity type, id and created time is returned
   *     (Optional query param).
   * @param metricsLimit If specified, defines the number of metrics to return.

   *     specified. Ignored otherwise. The maximum possible value for
   *     metricsLimit can be {@link Integer#MAX_VALUE}. If it is not specified

   *     metricsLimit will be considered as 1 i.e. latest single value of
   *     metric(s) will be returned. (Optional query param).
