Class InstrumentationInterceptStrategy

java.lang.Object
  extended by org.apache.camel.management.InstrumentationInterceptStrategy
All Implemented Interfaces:
InterceptStrategy

public class InstrumentationInterceptStrategy
extends Object
implements InterceptStrategy

This strategy class wraps targeted processors with a InstrumentationProcessor. Each InstrumentationProcessor has an embedded ManagedPerformanceCounter for monitoring performance metrics.

This class looks up a map to determine which PerformanceCounter should go into the InstrumentationProcessor for any particular target processor.

Description copied from interface: InterceptStrategy
This method is invoked by ProcessorDefinition.wrapProcessor(RouteContext, Processor) to give the implementor an opportunity to wrap the target processor in a route.

Important: See the class javadoc for advice on letting interceptor be compatible with the asynchronous routing engine.

Specified by:
wrapProcessorInInterceptors in interface InterceptStrategy
Parameters:
context - Camel context
definition - the model this interceptor represents
target - the processor to be wrapped
nextTarget - the next processor to be routed to
Returns:
processor wrapped with an interceptor or not wrapped.
Throws:
Exception - can be thrown
