public interface MetricExporterSpi
extends IgniteSpi

Metrics API currently has an experimental state. The API is stable enough but can be changed in future releases.

Exporter of metric information to the external recipient. Expected, that each implementation would support some specific protocol. Implementation of this Spi should work by pull paradigm. So after start SPI should respond to some incoming request. HTTP servlet or JMX bean are good examples of expected implementations.
