etm.core.monitor
Class NestedMonitor

java.lang.Object
  etm.core.monitor.EtmMonitorSupport
      etm.core.monitor.NestedMonitor

All Implemented Interfaces:

EtmMonitor, AggregationStateListener, EtmMonitorListener

public class NestedMonitor
extends EtmMonitorSupport

The NestedMonitor records nested EtmPoints as a tree using ThreadLocals to maintain the thread depend caller tree.

Be aware that leaking EtmPoints will lead to unexpected results - so always ensure you call EtmPoint.collect() in a finally clause.
