Java Distribution Summaries

Distribution Summaries are created using the Registry, which will be setup as part of application initialization. For example:

public class Server {

  private final DistributionSummary requestSize;

  @Inject
  public Server(Registry registry) {
    requestSize = registry.distributionSummary("server.requestSize");
  }

Then call record when an event occurs:

  public Response handle(Request request) {
    requestSize.record(request.sizeInBytes());
  }
}

Note: If the amount recorded is less than 0 the value will be dropped.
