Histograms

public Histograms(int columnCount,
                  int shift)

A Histograms object is a container for a map of namespaces to histograms (as defined by their associated LatencyBuckets) & their histogram properties

Parameters:

columnCount - number of histogram columns or "buckets"

shift - power of 2 multiple between each range bucket in histogram starting at bucket 3. The first 2 buckets are "<=1ms" and ">1ms".

Increment count of bucket corresponding to the namespace & elapsed time in nanoseconds.

getBuckets

public LatencyBuckets[] getBuckets(String namespace)

Return the LatencyBuckets for a given namespace

getMap
