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) invalid input: '&' 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".

Method Details

addLatency

public void addLatency(String namespace,
 LatencyType type,
 long elapsed)

getBuckets

public LatencyBuckets[] getBuckets(String namespace)

Return the LatencyBuckets for a given namespace

getMap

public ConcurrentHashMap<String,LatencyBuckets[]> getMap()

Return the histograms map
