Appendix E: Integrating with Existing Enterprise System Management : vCloud Director Notifications and Blocking Tasks Messages : Extension : Handling the Notification Messages
   
Handling the Notification Messages
The notification messages contain the operation triggering the event, the object type, and identifiers and names for organization, user, and object.
These can be used as markers for applications such as audit logging, Change Management, and Incident Management. If the application cannot correlate the IDs to present the objects properties in a user-consumable form, the extension application has to call back the vCloud API to extract these.
Use notification messages to start an operation that must follow another one. For example, enabling the public IPs of a vApp in a load balancer.
