Class HystrixServoMetricsPublisherCommand

java.lang.Object

com.netflix.hystrix.contrib.servopublisher.HystrixServoMetricsPublisherCommand

All Implemented Interfaces:

com.netflix.hystrix.strategy.metrics.HystrixMetricsPublisherCommand

public class HystrixServoMetricsPublisherCommand
extends java.lang.Object
implements com.netflix.hystrix.strategy.metrics.HystrixMetricsPublisherCommand

Concrete Implementation of HystrixMetricsPublisherCommand using Servo (https://github.com/Netflix/servo) This class should encapsulate all logic around how to pull metrics. This will allow any other custom Servo publisher to extend. Then, if that class wishes to override initialize(), that concrete implementation can choose by picking the set of semantic metrics and names, rather than providing an implementation of how.
