Interface MetricsSink

All Superinterfaces:

MetricsPlugin

All Known Implementing Classes:

FileSink, GraphiteSink

@InterfaceAudience.Public
@InterfaceStability.Evolving
public interface MetricsSink
extends MetricsPlugin

The metrics sink interface.

Implementations of this interface consume the MetricsRecord generated from MetricsSource. It registers with MetricsSystem which periodically pushes the MetricsRecord to the sink using putMetrics(MetricsRecord) method. If the implementing class also implements Closeable, then the MetricsSystem will close the sink when it is stopped.
