com.sun.enterprise.admin.monitor.registry.MonitoringRegistry
Provides component specific methods to enable components to register their Stats implementations for monitoring. Implementation of this interface enables a JSR77 Managed Resource's monitoring statistics to be presented through JMX's API through a DynamicMBean created on the fly and registered with the MBeanServer. Each registration method also provides the facility of passing in an implementation of MonitoringLevelListener interface. The purpose of that interface is to enable components to be notified of a change in monitoring level from/to OFF, LOW or HIGH. A notification pursuant to a change in monitoring level should result in a call to unregister previously registered Stats implementations. If the change is set at a level LOW or HIGH, a call to register alternative Stats implementations that correspond to the new monitoring level is to be made by the component. Consequently, a new MBean is registered with the MBeanServer so that clients may now request statistics corresponding to the monitoring level.
Registered Stats implementations can be unregistered through the component specific unregister() methods. @see com.sun.enterprise.admin.monitor.registry.MonitoringLevelListener.java @see com.sun.enterprise.admin.monitor.registry.MonitoringLevel.java @author Shreedhar Ganapathy @version $Revision: 1.5 $
