I currently have an Activity Notification set for our Auto Scaling Groups for 'launch' type. It fires based on any amount of launches. Is there a way to restrict the Notification to send only when we are over a certain amount of scaled instances? For example I have max 15 instances to scale to, I'd like to get Notifications only when we're over 10 scaled instances.

No, it is not possible to "restrict" the notification.

However, you could create an Amazon CloudWatch alarm on the GroupTotalInstances metric. When that metric exceeds a desired value, it can trigger a notification.

See: Monitoring CloudWatch metrics for your Auto Scaling groups and instances - Amazon EC2 Auto Scaling
