@MBean(objectName="LocalContainerStats",
       description="General statistic of local container.")
public class LocalContainerStatsImpl
extends AbstractContainerStats
implements ClusterContainerStats

Provide statistics of the local JVM instance. When the statistics collection is disabled, we return -1.
