AWSAutoScalingPredefinedMetricSpecification

Objective-C

@interface AWSAutoScalingPredefinedMetricSpecification

Swift

class AWSAutoScalingPredefinedMetricSpecification

Represents a predefined metric for a target tracking scaling policy to use with Amazon EC2 Auto Scaling.

Required parameters: [PredefinedMetricType]

  • The metric type. The following predefined metrics are available:

    • ASGAverageCPUUtilization - Average CPU utilization of the Auto Scaling group.

    • ASGAverageNetworkIn - Average number of bytes received on all network interfaces by the Auto Scaling group.

    • ASGAverageNetworkOut - Average number of bytes sent out on all network interfaces by the Auto Scaling group.

    • ALBRequestCountPerTarget - Number of requests completed per target in an Application Load Balancer target group.

    Declaration

    Objective-C

    @property (nonatomic) AWSAutoScalingMetricType predefinedMetricType;

    Swift

    var predefinedMetricType: AWSAutoScalingMetricType { get set }
  • A label that uniquely identifies a specific Application Load Balancer target group from which to determine the average request count served by your Auto Scaling group. You can’t specify a resource label unless the target group is attached to the Auto Scaling group.

    You create the resource label by appending the final portion of the load balancer ARN and the final portion of the target group ARN into a single value, separated by a forward slash (/). The format of the resource label is:

    app/my-alb/778d41231b141a0f/targetgroup/my-alb-target-group/943f017f100becff.

    Where:

    • app/<load-balancer-name>/<load-balancer-id> is the final portion of the load balancer ARN

    • targetgroup/<target-group-name>/<target-group-id> is the final portion of the target group ARN.

    To find the ARN for an Application Load Balancer, use the DescribeLoadBalancers API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable resourceLabel;

    Swift

    var resourceLabel: String? { get set }
