Proactive Evaluation

For steps on how to run this rule in proactive mode, see Evaluating Your Resources with AWS Config Rules. For this rule to return COMPLIANT in proactive mode, the resource configuration schema for the StartResourceEvaluation API needs to include the following inputs, encoded as a string:

"ResourceConfiguration":
...
{
   "LoadBalancerNames": "[my-load-balancer-1, my-load-balancer-2, my-load-balancer-3, ...]",
   "HealthCheckType": HealthCheckType*"
}

^*The valid values are EC2 (default), ELB, and VPC_LATTICE. The VPC_LATTICE health check type is reserved for use with VPC Lattice, which is in preview release and is subject to change. For more information, see Health checks for Auto Scaling instances in the Amazon EC2 Auto Scaling User Guide.
