我正在尝试使用@Timed(http://metrics.dropwizard.io/3.1.0/apidocs/com/codahale/metrics/annotation/package-summary.html)等注释自动将指标发布到我的MetricRegistry .

这不是开箱即用的.在搜索问题时,我发现了Codahale Metrics:在普通Java中使用@Timed指标注释,其中提到了这个工作的唯一方法是使用aspectj.我将此添加到我的项目中,但仍未在MetricRegistry中看到我的指标.

这是我的pom文件.我添加了一个librato库,它加载了com.codahale.metrics:metrics-annotation.

这就是我尝试使用指标的方式

@Metrics(registry = "default") // this.metricRegistry is default
public class Foo {
    @Inject
    private MetricRegistry metricRegistry;
    ...

    @Metered(name = "meterName")
    public void bar() { …

我正在尝试为Big Number图表创建两个指标的简单组合:

mean([
  series("metric.a", {}),
  series("metric.b", {})
])

但是当我这样做时,我收到以下错误.我的语法是否关闭？

Unable to execute composite: ["error": "Requested MD data from SD endpoint"].
