How to read and reset spring actuator metrics?

I'm using spring-boot.1.3.0, which provides ability to store custom metrics in memory as follows:

@Service
public class MyService {
    private CounterService counterService;
    private GaugeService gaucheService;

    @Autowired
    public MyService(CounterService counterService) {
        this.counterService = counterService;
    }

    public void exampleMethod() {
        this.counterService.increment("services.system.myservice.invoked");
    }
}

Question: how can I read the counted values from the CounterService and GaugeService programmatically?

@membersound's answer works, but I think it's better use

@Autowired
private MetricReader metricReader;

instead of 

@Autowired
private BufferMetricReader metrics;

@Autowired
private BufferMetricReader metrics;

int count = metrics.findOne("my.metrics.key").getValue().intValue();

The Javadoc shows a reset method: http://docs.spring.io/autorepo/docs/spring-boot/1.3.0.RELEASE/api/org/springframework/boot/actuate/metrics/CounterService.html

Reading has to be done from an exporter: http://docs.spring.io/autorepo/docs/spring-boot/1.3.0.RELEASE/api/org/springframework/boot/actuate/metrics/export/package-summary.html
