如何读取和复位弹簧执行器指标？

Question

我正在使用spring-boot.1.3.0，它提供了在内存中存储自定义metrics的功能，如下所示：

@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");
    }
}

问题：如何以编程方式从CounterService和GaugeService中读取计数值？

Answer 1

@Autowired
private BufferMetricReader metrics;

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

Answer 2

Javadoc显示了reset方法：http://docs.spring.io/autorepo/docs/spring-boot/1.3.0.RELEASE/api/org/springframework/boot/actuate/metrics/CounterService.html

必须从出口商那里阅读：http://docs.spring.io/autorepo/docs/spring-boot/1.3.0.RELEASE/api/org/springframework/boot/actuate/metrics/export/package-summary.html

Answer 3

@ membersound的答案有效，但我认为它更好用

@Autowired
private MetricReader metricReader;

代替

@Autowired
private BufferMetricReader metrics;
