For an Auto Scaling group replacement update, specifies how many instances must signal success for the update to succeed.
|min||Specifies the percentage of instances in an Auto Scaling replacement update that must signal success for the update to succeed.|
Specifies the percentage of instances in an Auto Scaling replacement update that must signal success for the update to succeed.
You can specify a value from 0 to 100. AWS CloudFormation rounds to the nearest tenth of a percent. For example, if you update five instances with a minimum successful percentage of 50, three instances must signal success. If an instance doesn't send a signal within the time specified by the Timeout property, AWS CloudFormation assumes that the instance wasn't created.
