Method Summary

Modifier and Type	Method and Description
static java.util.NavigableSet<java.lang.Long>	buckets(HistogramConfig histogramConfig) 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.
