Class ConnectionStatistics

  • All Implemented Interfaces:
    Connection.Listener, Dumpable, LifeCycle
    Direct Known Subclasses:
    IncludeExcludeConnectionStatistics, ServerConnectionStatistics
    @ManagedObject("Tracks statistics on connections")
@Deprecated(since="2021-05-27")
public class ConnectionStatistics
extends AbstractLifeCycle
implements Connection.Listener, Dumpable
    Deprecated.
    The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.

    A Connection.Listener that tracks connection statistics.

    Adding an instance of this class as a bean to a ServerConnector or ConnectionFactory (for the server) or to HttpClient (for the client) will trigger the tracking of the connection statistics for all connections managed by the server or by the client.

    The statistics for a connection are gathered when the connection is closed.

    ConnectionStatistics instances must be started to collect statistics, either as part of starting the whole component tree, or explicitly if the component tree has already been started.
