This information is automatically exposed to JMX when using Jetty's JMX facilities. Otherwise it is obtainable by downcasting to concrete classes: HttpDestination destination = (HttpDestination)httpClient.getDestination(...); DuplexConnectionPool connectionPool = (DuplexConnectionPool)destination.getConnectionPool(); You may get different concrete classes based on the transport you have chosen, so maybe you need additional "instanceof" around. HttpDestination and DuplexConnectionPool (and their parent classes) have methods annotated with @ManagedAttribute and those are exported to JMX and are probably those you're interested in. -- Simone Bordet ---- http://cometd.org http://webtide.com Developer advice, training, services and support from the Jetty & CometD experts. _______________________________________________ jetty-users mailing list [email protected] To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/jetty-users
