outcomeAlarms

The outcome alarm for practice runs is a required Amazon CloudWatch alarm that you specify that ends a practice run when the alarm is in an ALARM state.

Configure the alarm to monitor the health of your application when traffic is shifted away from an Availability Zone during each weekly practice run. You should configure the alarm to go into an ALARM state if your application is impacted by the zonal shift, and you want to stop the zonal shift, to let traffic for the resource return to the Availability Zone.
