3. Listeners

Listeners allow users to define actions that will be taken in response to changes in the monitored elements, e.g., when the deployment layout changes or when new statistical data has been received.

There are two kinds of listeners:

• DomainListener acts upon changes in the DDS entities of the deployment or new statistical data arrives.

• PhysicalListener acts upon changes in the physical entities of the deployment.
