Interface MetricExporterSpi

All Superinterfaces:

IgniteSpi

All Known Implementing Classes:

JmxMetricExporterSpi, LogExporterSpi, NoopMetricExporterSpi, OpenCensusMetricExporterSpi, org.apache.ignite.internal.processors.metric.PushMetricsExporterAdapter

public interface MetricExporterSpi
extends IgniteSpi

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.

Ignite provides the following MetricExporterSpi implementation:

• JmxMetricExporterSpi
• LogExporterSpi
• org.apache.ignite.internal.processors.metric.sql.SqlViewMetricExporterSpi
• org.apache.ignite.spi.metric.opencensus.OpenCensusMetricExporterSpi
