Interface MemoryMonitorMBean

All Superinterfaces:

SelfEmailingMBean

public interface MemoryMonitorMBean
extends SelfEmailingMBean

Provides percentage-based monitoring of important memory usage statistics whereas built in Java 5 MBeans operate solely in terms of fixed byte thresholds, which does not translate well from site to site or during the lifespan of a single process when self-tuning heap features are used.
