>
> Ambari agent hosts will receive the alert definitions they are responsible for scheudling via a new command type that is pushed down in the following scenarios:
> - Agent Registration
> - AlertDefinition invalidation
> The commands will be present in a heartbeat response if the server has determined that it thinks the agents need to be made away of which alert definitions are required to be scheduled. A hash value will also be sent along with the commands so that agents can decide if they do not need to reschedule their jobs.
