Class InstrumentedHttpChannelListener

java.lang.Object

io.dropwizard.metrics.jetty10.InstrumentedHttpChannelListener

All Implemented Interfaces:

EventListener, org.eclipse.jetty.server.HttpChannel.Listener

public class InstrumentedHttpChannelListener
extends Object
implements org.eclipse.jetty.server.HttpChannel.Listener

A Jetty HttpChannel.Listener implementation which records various metrics about underlying channel instance. Unlike InstrumentedHandler that uses internal API, this class should be future proof. To install it, just add instance of this class to Connector as bean.
