What happens when an event is received

Summary

I'm getting a bit lost due to ambiguity on the pages about events and alerts. Thus have a hard time grasping the details.

For context: my environment has one cluster with a a flaky network link. The goal is for UM to report when connectivity has been restored via an outgoing trap.
I think somthing like this can be accomplished by letting UM trigger an alert when the event status changes to obsolete.
How to do that isn't clear as I can't work out if/how alerts can trigger in detail.

e.g. * the page starts with "When Unified Manager receives an event".
The flow chart indicates UM generates events which seems very different from receiving events.
A more accurate title might be 'What happens when an event is generated'.

• The flow chart oversimplified what happens: it implies that alerts are outgoing email notifications.
  it also seems to imply that an event triggers an alert.
  I read “By default, alerts are not sent for events as they move into the Resolved and Obsolete states.” (https://docs.netapp.com/us-en/active-iq-unified-manager/events/task_disable_alerts_for_resolved_and_obsolete_events.html)

The latter suggests that an event status change triggers an alert. This would also imply that the alert details (trap) depend on the status change.
This is not clear from the flow chart & most pages of the manual.
if my interpretation is accurate:please make it apparent it is that status_change of an event that triggers an alert.
(and that by default only a change to new/acknowleged trigger alerts).

• on the 'What Event Management System events are' page the explaination about EMS is ambigious;
  is it refering the ONTAP EMS system or Event handling in UM (or both) ?
  On page 'EMS events that are added automatically to Unified Manager' it is clear that it is about ONTAP EMS.
  I have the impression that UM events are comprised of ONTAP EMS events and events generated by UM.

• the page 'Notifications page' decribes notifications such that they are remarkably like alerts:
  "You can configure the Unified Manager server to send notifications when an event is generated or when it is assigned to a user."
  Are the notifications different from alerts?
