public class JMXConnectionNotification extends Notification
Notification emitted when a client connection is opened or closed or when notifications are lost. These notifications are sent by connector servers (instances of
JMXConnectorServer
) and by connector clients (instances ofJMXConnector
). For certain connectors, a session can consist of a sequence of connections. Connection-opened and connection-closed notifications will be sent for each one.The notification type is one of the following:
Type Meaning jmx.remote.connection.opened
A new client connection has been opened. jmx.remote.connection.closed
A client connection has been closed. jmx.remote.connection.failed
A client connection has failed unexpectedly. jmx.remote.connection.notifs.lost
A client connection has potentially lost notifications. This notification only appears on the client side. The
timeStamp
of the notification is a time value (consistent withSystem.currentTimeMillis()
) indicating when the notification was constructed.- Since:

JMXConnectionNotification
public JMXConnectionNotification(String type, Object source, String connectionId, long sequenceNumber, String message, Object userData)
Constructs a new connection notification. Thesource
of the notification depends on whether it is being sent by a connector server or a connector client:- For a connector server, if it is registered in an MBean
server, the source is the
ObjectName
under which it is registered. Otherwise, it is a reference to the connector server object itself, an instance of a subclass ofJMXConnectorServer
. - For a connector client, the source is a reference to the
connector client object, an instance of a class implementing
JMXConnector
.
- Parameters:
type
- the type of the notification. This is usually one of the constantsOPENED
,CLOSED
,FAILED
,NOTIFS_LOST
. It is not an error for it to be a different string.source
- the connector server or client emitting the notification.connectionId
- the ID of the connection within its connector server.sequenceNumber
- a non-negative integer. It is expected but not required that this number will be greater than any previoussequenceNumber
in a notification from this source.message
- an unspecified text message, typically containing a human-readable description of the event. Can be null.userData
- an object whose type and meaning is defined by the connector server. Can be null.- Throws:
NullPointerException
