ELB Instance Health
An ELB Instance Health resource represents the current health status of an individual Amazon EC2 instance as reported by an Elastic Load Balancer. The data is returned by the DescribeInstanceHealth
API call and indicates whether the instance is InService
, OutOfService
, or in a transitional state (e.g. Draining
, Unknown
). By tracking these objects Overmind can warn you when a deployment will place traffic on unhealthy instances or reduce overall service capacity.
