Package io.micrometer.core.instrument.distribution

Class TimeWindowFixedBoundaryHistogram

java.lang.Object

io.micrometer.core.instrument.distribution.TimeWindowFixedBoundaryHistogram

All Implemented Interfaces:

Histogram, AutoCloseable

public class TimeWindowFixedBoundaryHistogram
extends Object

A histogram implementation that does not support precomputed percentiles but supports aggregable percentile histograms and SLA boundaries. There is no need for a high dynamic range histogram and its more expensive memory footprint if all we are interested in is fixed histogram counts.

Since:

1.0.3
