HealthCheckGracePeriod Property
AmazonAmazon.AutoScaling.ModelCreateAutoScalingGroupRequestHealthCheckGracePeriod Did this page help you?   Yes   No    Tell us about it...
Length of time in seconds after a new Amazon EC2 instance comes into service that Auto Scaling starts checking its health. During this time any health check failure for the that instance is ignored. This is required if you are adding ELB health check. Frequently, new instances need to warm up, briefly, before they can pass a health check. To provide ample warm-up time, set the health check grace period of the group to match the expected startup period of your application.
