   The following Annotations exist, see below for common fields:

negative.code: The `MetricRegistry` stores the metrics and metadata information.
  There is one `MetricRegistry` instance for each of the scopes listed in <<scopes>>.
  
  Metrics can be added to or retrieved from the registry either using the <<api-annotations, Metrics Annotations>> or using the `MetricRegistry` object directly.
