Class ShutdownMonitor

java.lang.Object
org.eclipse.jetty.server.ShutdownMonitor
public class ShutdownMonitor extends Object
Shutdown/Stop Monitor thread.

This thread listens on the host/port specified by the STOP.HOST/STOP.PORT system parameter (defaults to 127.0.0.1/-1 for not listening) for request authenticated with the key given by the STOP.KEY system parameter for admin requests.

If the stop port is set to zero, then a random port is assigned and the port number is printed to stdout.

Commands "stop" and "status" are currently supported.

  • Constructor Details

    • ShutdownMonitor

      private ShutdownMonitor()
      Creates a ShutdownMonitor using configuration from the System properties.

      STOP.PORT = the port to listen on (empty, null, or values less than 0 disable the stop ability)
      STOP.KEY = the magic key/passphrase to allow the stop

      Note: server socket will only listen on localhost, and a successful stop will issue a System.exit() call.
