spring - 如何读取和重置弹簧执行器指标？

Question

我正在使用spring-boot.1.3.0，它提供了将自定义存储metrics在内存中的能力，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和读取计数值？GaugeService

Answer 1

@Autowired
private BufferMetricReader metrics;

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

Answer 2

Javadoc 显示了一种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;
