Example: changes to the local configuration of the integration node

An event is published to a system topic when an entity is created, changed, or deleted.

Notification of changes to the integration node configuration (creation, change, or deletion of entities) is provided by publishing events.

One event is published for each configuration request message that is received and processed by an integration server within the integration node. The event can contain information that reflects complex configuration changes to multiple entities within the integration node.

The body of each publication is the part of the configuration request that causes the event to be triggered. If an integration server is renamed, subsequent publications that report the state of that integration server use the new name.

These events are published non-persistently as non-retained publications.

Only create, change, and delete actions on the message flow are reported.

The following figure shows an example notification when a message flow is created. The number of attributes mentioned in the example can vary.
