Package org.apache.cassandra.metrics

Class CassandraMetricsRegistry

java.lang.Object

com.codahale.metrics.MetricRegistry

org.apache.cassandra.metrics.CassandraMetricsRegistry

All Implemented Interfaces:

com.codahale.metrics.Metric, com.codahale.metrics.MetricSet

public class CassandraMetricsRegistry
extends com.codahale.metrics.MetricRegistry

Makes integrating 3.0 metrics API with 2.0.

The 3.0 API comes with poor JMX integration
