resources
The resources to include in a monitor, which you provide as a set of Amazon Resource Names (ARNs). Resources can be Amazon Virtual Private Cloud VPCs, Network Load Balancers (NLBs), Amazon CloudFront distributions, or Amazon WorkSpaces directories. You can add a combination of VPCs and CloudFront distributions, or you can add WorkSpaces directories, or you can add NLBs. You can't add NLBs or WorkSpaces directories together with any other resources. If you add only VPC resources, at least one VPC must have an Internet Gateway attached to it, to make sure that it has internet connectivity.
You can specify this field for a monitor update only if the
Resourcesfield is empty.
