Class InstrumentationInterceptStrategy

java.lang.Object

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
