You can use blocking tasks and notifications to configure vCloud Director to send AMQP messages triggered by certain events.

Some of these messages are simply notifications that the event has occurred. Other messages publish information to a designated AMQP endpoint indicating that a requested action has been blocked and is pending action by a client application bound to that endpoint. These messages are known as blocking tasks.

A system administrator can configure a system-wide set of blocking tasks that are subject to a programmatic action by an AMQP client.
