Overview

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

Only the Amazon Web Services that you’re using send metrics to Amazon CloudWatch. To determine whether a desired metric already exists by looking up its namespace and dimension using the CloudWatch metrics dashboard in the console, follow the procedure in [Monitor your resources using CloudWatch] in the *Application Auto Scaling User Guide*.

#resource_labelString

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 Spot Fleet or ECS service.

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/&lt;load-balancer-name&gt;/&lt;load-balancer-id&gt; is the final portion of the load balancer ARN

  • targetgroup/&lt;target-group-name&gt;/&lt;target-group-id&gt; is the final portion of the target group ARN.

To find the ARN for an Application Load Balancer, use the

DescribeLoadBalancers][1

API operation. To find the ARN for the

target group, use the [DescribeTargetGroups] API operation.
