You might need to refresh the page if it doesn’t appear automatically. Under “Take the Action”, configure the drop-down lists and text boxes to Add 1 capacity units.

This sets our Auto Scaling Policy to trigger when the alarm goes off, while also requiring 600 seconds (10 minutes) to pass before the policy can be applied again.
