TrafficSourceIdentifier

Identifying information for a traffic source.

Identifier

Identifies the traffic source.

For Application Load Balancers, Gateway Load Balancers, Network Load Balancers, and VPC Lattice, this will be the Amazon Resource Name (ARN) for a target group in this account and Region. For Classic Load Balancers, this will be the name of the Classic Load Balancer in this account and Region.

For example:

  • Application Load Balancer ARN: arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/1234567890123456

  • Classic Load Balancer name: my-classic-load-balancer

  • VPC Lattice ARN: arn:aws:vpc-lattice:us-west-2:123456789012:targetgroup/tg-1234567890123456

To get the ARN of a target group for a Application Load Balancer, Gateway Load Balancer, or Network Load Balancer, or the name of a Classic Load Balancer, use the Elastic Load Balancing DescribeTargetGroups and DescribeLoadBalancers API operations.

To get the ARN of a target group for VPC Lattice, use the VPC Lattice GetTargetGroup API operation.
