Class InstrumentedResourceMethodApplicationListener

java.lang.Object

com.codahale.metrics.jersey2.InstrumentedResourceMethodApplicationListener

All Implemented Interfaces:

org.glassfish.jersey.server.model.ModelProcessor, org.glassfish.jersey.server.monitoring.ApplicationEventListener

@Provider
public class InstrumentedResourceMethodApplicationListener
extends Object
implements org.glassfish.jersey.server.monitoring.ApplicationEventListener, org.glassfish.jersey.server.model.ModelProcessor

An application event listener that listens for Jersey application initialization to be finished, then creates a map of resource method that have metrics annotations.

Finally, it listens for method start events, and returns a RequestEventListener that updates the relevant metric for suitably annotated methods when it gets the request events indicating that the method is about to be invoked, or just got done being invoked.

Constructor Detail

InstrumentedResourceMethodApplicationListener

public InstrumentedResourceMethodApplicationListener(com.codahale.metrics.MetricRegistry metrics)

Construct an application event listener using the given metrics registry.

When using this constructor, the InstrumentedResourceMethodApplicationListener should be added to a Jersey ResourceConfig as a singleton.

Parameters:

metrics - a MetricRegistry

InstrumentedResourceMethodApplicationListener

public InstrumentedResourceMethodApplicationListener(com.codahale.metrics.MetricRegistry metrics,
                                                     com.codahale.metrics.Clock clock,
                                                     boolean trackFilters)

Constructs a custom application listener.

Parameters:

metrics - the metrics registry where the metrics will be stored

clock - the Clock to track time (used mostly in testing) in timers

trackFilters - whether the processing time for request and response filters should be tracked
