类 ExampleRegionObserverWithMetrics

java.lang.Object

org.apache.hadoop.hbase.coprocessor.example.ExampleRegionObserverWithMetrics

所有已实现的接口:

Coprocessor, RegionCoprocessor

@InterfaceAudience.Private
public class ExampleRegionObserverWithMetrics
extends Object
implements RegionCoprocessor

An example coprocessor that collects some metrics to demonstrate the usage of exporting custom metrics from the coprocessor.

These metrics will be available through the regular Hadoop metrics2 sinks (ganglia, opentsdb, etc) as well as JMX output. You can view a snapshot of the metrics by going to the http web UI of the regionserver page, something like http://myregionserverhost:16030/jmx
