Class DropwizardMetricServices

java.lang.Object

org.springframework.boot.actuate.metrics.dropwizard.DropwizardMetricServices

All Implemented Interfaces:

CounterService, GaugeService

public class DropwizardMetricServices
extends Object
implements CounterService, GaugeService

A GaugeService and CounterService that sends data to a Dropwizard MetricRegistry based on a naming convention.

• Updates to increment(String) with names in "meter.*" are treated as Meter events
• Other deltas are treated as simple Counter values
• Inputs to submit(String, double) with names in "histogram.*" are treated as Histogram updates
• Inputs to submit(String, double) with names in "timer.*" are treated as Timer updates
• Other metrics are treated as simple Gauge values (single valued measurements of type double)
