Constructor Details

HistogramSnapshot

public HistogramSnapshot(MetricMetadata metadata,
 Collection<HistogramSnapshot.HistogramDataPointSnapshot> data)

To create a new HistogramSnapshot, you can either call the constructor directly or use the builder with builder().

Parameters:

metadata - see MetricMetadata for naming conventions.

data - the constructor will create a sorted copy of the collection.

HistogramSnapshot

public HistogramSnapshot(boolean isGaugeHistogram,
 MetricMetadata metadata,
 Collection<HistogramSnapshot.HistogramDataPointSnapshot> data)

Use this with the first parameter true to create a snapshot of a Gauge Histogram. The data model for Gauge Histograms is the same as for regular histograms, except that bucket values are semantically gauges and not counters. See openmetrics.io for more info on Gauge Histograms.

Method Details

isGaugeHistogram

public boolean isGaugeHistogram()

getDataPoints

public List<HistogramSnapshot.HistogramDataPointSnapshot> getDataPoints()
