We would like to have event notifications of load balancing resource state changes: - provisioning_status changes (including all create/update/delete events) - operating_status changes (member up/down, etc) This enables use cases like auditing, billing and monitoring with immediate notifications to a message bus and reduces the need to poll eventually large chunks of data from the REST API. - Applications can monitor the provisioning and operating statuses of objects. - Applications listen to object changes and update billing information. - Applications can collect usage information about objects. - Applications can audit and log actions with objects.
