    • createGauge

      Closeable createGauge(String name, String description, String unit, Supplier<Double> valueProvider, Tags tags)
      Creates the Observable Gauge type of Metric. Where the value provider will be called at a certain frequency to capture the value.
      Parameters:
      name - name of the observable gauge.
      description - any description about the metric.
      unit - unit of the metric.
      valueProvider - value provider.
      tags - attributes/dimensions of the metric.
      Returns:
      closeable to dispose/close the Gauge metric.

    • createGauge

      Closeable createGauge(String name, String description, String unit, Supplier<TaggedMeasurement> value)

      Parameters:
      name - name of the observable gauge.
      description - any description about the metric.
      unit - unit of the metric.
      value - value provider.
