Class StatsProviderUtil

java.lang.Object

org.apache.jackrabbit.oak.plugins.metric.util.StatsProviderUtil

public class StatsProviderUtil
extends Object

Util class to generate a name for Stats implementations that can be used for creating labels in prometheus.

Usage - StatsProviderUtil(<StatisticsProvider Object>).getHistoStats().apply(metricName, labels) where metricName is a String to denote the metric name and labels is map of label values. Resultant metric will be created with a name as follows - metricName;labelName1=labelValue1;labelName2=labelValue2. This can then be translated by a consuming alerting system like prometheus into metric name and labels separately.
