All Implemented Interfaces:

com.codahale.metrics.Reporter, Closeable, AutoCloseable, org.apache.hadoop.metrics2.MetricsSource

public class HadoopMetrics2Reporter
extends com.codahale.metrics.ScheduledReporter
implements org.apache.hadoop.metrics2.MetricsSource

A Reporter which also acts as a Hadoop Metrics2 MetricsSource. Configure it like other Reporters.

 final HadoopMetrics2Reporter metrics2Reporter = HadoopMetrics2Reporter.forRegistry(metrics)
     .build(DefaultMetricsSystem.initialize("Phoenix"), // The application-level name
            "QueryServer", // Component name
            "Phoenix Query Server", // Component description
            "General"); // Name for each metric record

 metrics2Reporter.start(30, TimeUnit.SECONDS);
