Interface MetricsHeapMemoryManagerSource

All Superinterfaces:

BaseSource

All Known Implementing Classes:

MetricsHeapMemoryManagerSourceImpl

@InterfaceAudience.Private
public interface MetricsHeapMemoryManagerSource
extends BaseSource

This interface will be implemented by a MetricsSource that will export metrics from HeapMemoryManager in RegionServer into the hadoop metrics system.
