io.micrometer.core.instrument.distribution.PercentileHistogramBuckets

public class PercentileHistogramBuckets
extends java.lang.Object

Generator for a set of histogram buckets intended for use by a monitoring system that supports aggregable percentile approximations such as Prometheus' histogram_quantiles or Atlas' :percentiles.

Method Summary

Modifier and Type	Method and Description
static java.util.NavigableSet<java.lang.Long>	buckets(DistributionStatisticConfig distributionStatisticConfig) Pick values from a static set of percentile buckets that yields a decent error bound on most real world timers and distribution summaries because monitoring systems like Prometheus require us to report the same buckets at every interval, regardless of where actual samples have been observed.

Method Detail

buckets

public static java.util.NavigableSet<java.lang.Long> buckets(DistributionStatisticConfig distributionStatisticConfig)

Pick values from a static set of percentile buckets that yields a decent error bound on most real world timers and distribution summaries because monitoring systems like Prometheus require us to report the same buckets at every interval, regardless of where actual samples have been observed.

Parameters:

distributionStatisticConfig - A configuration the governs how many buckets to produce based on its minimum and maximum expected values..

Returns:

The set of histogram buckets for use in computing aggregable percentiles.
