All Superinterfaces:

Metric

public interface GaugeDoubleMetric
extends Metric

Metric based on a gauge returning double values.

A GaugeDoubleMetric is created by MetricManager.register(MetricName, GaugeDouble).

Example:

  class FreeMemoryGauge implements GaugeDouble {

      public double getValue() {
        return mxBean.getFreeMemory() / mxBean.getTotalMemory();
      }
    }


  GaugeDoubleMetric gauge = MetricManager.register("jvm.memory.pctfree", freeMemoryGauge);

Note that metric-core registers some core JVM gauges that include threads, memory and garbage collection.
