Class TimeScaleCumulativeHistogram

java.lang.Object

org.springframework.metrics.instrument.stats.hist.CumulativeHistogram<java.lang.Double>

org.springframework.metrics.instrument.stats.hist.TimeScaleCumulativeHistogram

All Implemented Interfaces:

Histogram<java.lang.Double>

public class TimeScaleCumulativeHistogram
extends CumulativeHistogram<java.lang.Double>

A cumulative histogram whose bucket tag values represent a measure of time. This class preserves the dimension of this time so that the histogram's bucket tags can be scaled to the base unit of time that the monitoring backend expects. Calls to CumulativeHistogram.observe(double) are expected to be made with a measure of time whose scale matches this histogram's time scale.
