PredefinedMetricSpecification - Amazon EC2 Auto Scaling

PredefinedMetricSpecification

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

Contents

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.

Type: String

Valid Values: ASGAverageCPUUtilization | ASGAverageNetworkIn | ASGAverageNetworkOut | ALBRequestCountPerTarget

Required: Yes

ResourceLabel

Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group attached to the Auto Scaling group.

Elastic Load Balancing sends data about your load balancers to Amazon CloudWatch. CloudWatch collects the data and specifies the format to use to access the data. The format is app/load-balancer-name/load-balancer-id/targetgroup/target-group-name/target-group-id , where

  • app/load-balancer-name/load-balancer-id is the final portion of the load balancer ARN, and

  • 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.

Type: String
