#default_instance_warmup ⇒ Integer
The amount of time, in seconds, until a new instance is considered
to have finished initializing and resource consumption to become
stable after it enters the InService
state.
During an instance refresh, Amazon EC2 Auto Scaling waits for the warm-up period after it replaces an instance before it moves on to replacing the next instance. Amazon EC2 Auto Scaling also waits for the warm-up period before aggregating the metrics for new instances with existing instances in the Amazon CloudWatch metrics that are used for scaling, resulting in more reliable usage data. For more information, see Set the default instance warmup for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.
To manage various warm-up settings at the group level, we recommend
that you set the default instance warmup, even if it is set to 0
seconds. To remove a value that you previously set, include the
property but specify -1
for the value. However, we strongly
recommend keeping the default instance warmup enabled by specifying
a value of 0
or other nominal value.

health checks after they enter the InService
state. For more
information, see Set the health check grace period for an Auto
Scaling group in the Amazon EC2 Auto Scaling User Guide.
