ConnectorEndPointFactoryMonitoringLevelListener

public final class ConnectorEndPointFactoryMonitoringLevelListener extends Object implements com.sun.enterprise.admin.monitor.registry.MonitoringLevelListener
Provides an implementation of the MonitoringLevelListener interface to receive callbacks from admin regarding change in the monitoring level. Though there are 3 monitoring levels defined by JSR77, we support only 2 levels - OFF and ON (HIGH/LOW). So essentially, HIGH and LOW for us is only ON
