Class MetricsCoprocessor

java.lang.Object

org.apache.hadoop.hbase.coprocessor.MetricsCoprocessor

@InterfaceAudience.Private
public class MetricsCoprocessor
extends Object

Utility class for tracking metrics for various types of coprocessors. Each coprocessor instance creates its own MetricRegistry which is exported as an individual MetricSource. MetricRegistries are ref counted using the hbase-metric module interfaces.
