Package com.inductiveautomation.ignition.gateway.metrics

Class DescriptiveRatioGauge

java.lang.Object

com.inductiveautomation.ignition.gateway.metrics.DescriptiveRatioGauge

All Implemented Interfaces:

com.codahale.metrics.Gauge<Double>, com.codahale.metrics.Metric, DescriptiveMetric

public abstract class DescriptiveRatioGauge
extends Object
implements com.codahale.metrics.Gauge<Double>, DescriptiveMetric

This class is mostly a copy of the RatioGauge from the Metrics library. The difference is that the Ratio itself and its numerator and denominator are exposed so that the gauge can be rendered as a radio of X over Y rather than just as a number.
