<p>
The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing
target health checks after a task has first started. This is only valid if your service is configured to use a
load balancer. If your service's tasks take a while to start and respond to Elastic Load Balancing health checks,
you can specify a health check grace period of up to 2,147,483,647 seconds. During that time, the Amazon ECS
service scheduler ignores the Elastic Load Balancing health check status. This grace period can prevent the ECS
service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.
