Constructors Summary
public HTTPListenerStatsImpl(String domain, int port)
Creates a new instance of HTTPListenerStatsImpl The ObjectNames of the ThreadPool & GlobalRequestProcessor MBeans follow the pattern: :type=ThreadPool,name=http :type=GlobalRequestProcessor,name=http for example: server:type=ThreadPool,name=http1043

param
domain domain in which Tomcat's MBeans are registered This is usually the name of the virtual-server, to which this listener belongs
param
port port at which the listener is receiving requests
