MetricsSource (Apache HBase - Server 2.1.3 API)

java.lang.Object
- org.apache.hadoop.hbase.replication.regionserver.MetricsSource

所有已实现的接口:

BaseSource
```
@InterfaceAudience.LimitedPrivate(value="Replication")
public class MetricsSource
extends Object
implements BaseSource
```
This class is for maintaining the various replication statistics for a source and publishing them through the metrics interfaces.
