```
public class MetricRegistryMetricReader
extends Object
implements MetricReader, com.codahale.metrics.MetricRegistryListener
```
A Spring Boot MetricReader that reads metrics from a Dropwizard MetricRegistry. Gauges and Counters are reflected as a single value. Timers, Meters and Histograms are expanded into sets of metrics containing all the properties of type Number.
