如何读取和复位弹簧执行器指标？

Question

我使用spring-boot.1.3.0，它提供了将自定义metrics存储在内存中的功能，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读取计算值？

Answer 1

df1 <- structure(list(max1 = c("x9", "x5"), max2 = c("x8",
"x3"), max3 = c("x7", 
"x4"), max4 = c("x6", "x6"), max5 = c("x10", "x10"), 
max6 = c("x5", 
"x1"), max7 = c("x4", "x7"), max8 = c("x2", "x2"), 
max9 = c("x1", 
"x8"), max10 = c("x3", "x9")), .Names = c("max1", "max2", 
"max3", 
"max4", "max5", "max6", "max7", "max8", "max9", "max10"), 
class = "data.frame", row.names = c(NA, -2L))


 lvls <- unique(unlist(df1))
 lvls2 <- c("abc", "vb", "ab", "fg", "cf", "qw", "cd",
              "zx", "gh", "er")

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

阅读必须从出口商处完成：http://docs.spring.io/autorepo/docs/spring-boot/1.3.0.RELEASE/api/org/springframework/boot/actuate/metrics/export/package-summary.html

@membersound的答案有效，但我认为最好使用

@Autowired
private MetricReader metricReader;

代替

@Autowired
private BufferMetricReader metrics;
