Package org.eclipse.jetty.io
Class ConnectionStatistics
java.lang.Object
org.eclipse.jetty.util.component.AbstractLifeCycle
org.eclipse.jetty.io.ConnectionStatistics
- All Implemented Interfaces:
Connection.Listener
,Dumpable
,LifeCycle
- Direct Known Subclasses:
IncludeExcludeConnectionStatistics
,ServerConnectionStatistics
@ManagedObject("Tracks statistics on connections")
public class ConnectionStatistics
extends AbstractLifeCycle
implements Connection.Listener, Dumpable
A Connection.Listener
that tracks connection statistics.
Adding an instance of this class as a bean to a server Connector (for the server) or to HttpClient (for the client) will trigger the tracking of the connection statistics for all connections managed by the server Connector or by HttpClient.
