3 | This is an implementation of [HystrixMetricsPublisher](http://netflix.github.com/Hystrix/javadoc/index.html?com/netflix/hystrix/strategy/metrics/HystrixMetricsPublisher.html) that publishes metrics using [Coda Hale Metrics](http://metrics.codahale.com) version 3. If you are using Yammer Metrics version 2, please use the [hystrix-yammer-metrics-publisher](../hystrix-yammer-metrics-publisher) module instead.
