类 StatCollector

java.lang.Object

org.apache.mina.management.StatCollector

public class StatCollector
extends java.lang.Object

Collects statistics of an IoService. It's polling all the sessions of a given IoService. It's attaching a IoSessionStat object to all the sessions polled and filling the throughput values. Usage :

 IoService service = ...
 StatCollector collector = new StatCollector( service );
 collector.start();
 

By default the StatCollector is polling the sessions every 5 seconds. You can give a different polling time using a second constructor.
