Examples with QmfEvent org.apache.qpid.qmf2.common.QmfEvent used on opensource projects

Example 1 with QmfEvent

use of org.apache.qpid.qmf2.common.QmfEvent in project qpid by apache.

the class ConnectionLogger method onEvent.

/**
 * Listener for QMF2 WorkItems
 * <p>
 * This method looks for clientConnect or clientDisconnect Events and uses these as a trigger to log the new
 * connection state when the next Heartbeat occurs.
 * <p>
 * There are a couple of reasons for using this approach rather than just calling logConnectionInformation()
 * as soon as we see the clientConnect or clientDisconnect Event.
 * <p>
 * 1. We could potentially have lots of connection Events and redisplaying all of the connections for each
 *    Event is likely to be confusing.
 * <p>
 * 2. When a clientConnect Event occurs we don't have all of the informatin that we might need, for example this
 *    application checks the Session and Subscription information and also optionally Queue and Binding information.
 *    Creating Sessions/Subscriptions won't generally occur until some (possibly small, but possibly not) time
 *    after the Connection has been made. The approach taken here reduces spurious assertions that a Session is
 *    probably a "producer only" Session. As one of the use-cases for this tool is to attempt to flag up "producer
 *    only" Sessions we want to try and make it as reliable as possible.

Example 2 with QmfEvent

use of org.apache.qpid.qmf2.common.QmfEvent in project qpid by apache.

the class ConnectionAudit method onEvent.

/**
 * Handles WorkItems delivered by the Console.
 * <p>
 * If we receive an EventReceivedWorkItem check if it is a subscribe event. If it is we check if the whitelist has
 * changed, and if it has we re-read it. We then extract the queue name, exchange name, binding, connection address
 * and timestamp and validate with the whitelsist.
 * <p>
 * If we receive an AgentRestartedWorkItem we revalidate all subscriptions as it's possible that a client connection
 * could have been made to the broker before ConnectionAudit has successfully re-established its own connections.
 * @param wi a QMF2 WorkItem object
 */

    if (wi instanceof EventReceivedWorkItem) {
