new autoscaling.AutoScalingGroup(this, 'ASG', {
  vpc,

---

minSuccessPercentage?

Type: number (optional, default: 100)

The percentage of signals that need to be successful.

If this number is less than 100, a percentage of signals may be failure signals while still succeeding the creation or update in CloudFormation.

---

timeout?

Type: Duration (optional, default: Duration.minutes(5))

How long to wait for the signals to be sent.

This should reflect how long it takes your instances to start up (including instance start time and instance initialization time).
