Class MetricManager

java.lang.Object

org.apache.dubbo.metrics.MetricManager

public class MetricManager
extends Object

The design concept is heavily borrowed from SLF4j (http://www.slf4j.org/), the logging framework. The application only depends on the metrics api. The implementation will be dynamically bound. If the implementation if not found in classpath, by default the NOPMetricManager will be bound.
