Example 17 with Notification

use of javax.management.Notification in project camel by apache.

    // we should only get 5 messages, which is 1/2 the number of times we touched the object.

Example 20 with Notification

use of javax.management.Notification in project camel by apache.

the class JmxNotificationEventNotifier method notify.

public void notify(EventObject event) throws Exception {
    if (notificationBroadcaster != null) {
        // its recommended to send light weight events and we don't want to have the entire Exchange/CamelContext etc
        // serialized as these are the typical source of the EventObject. So we use our own source which is just
        // a human readable name, which can be configured.
        String type = event.getClass().getSimpleName();
        String message = event.toString();
        Notification notification = new Notification(type, source, counter.getAndIncrement(), message);
        LOG.trace("Broadcasting JMX notification: {}", notification);
        notificationBroadcaster.sendNotification(notification);
    }
