property of the AWS::AutoScaling::ScalingPolicy PredictiveScalingMetricSpecification property
type.
For more information, see Predictive scaling in the Amazon EC2 Auto Scaling User Guide.
Syntax
To declare this entity in your Amazon CloudFormation template, use the following syntax:
JSON
{ "PredefinedMetricType" :
String
, "ResourceLabel" :String
}
YAML
PredefinedMetricType:
String
ResourceLabel:String
Properties
PredefinedMetricType
-
Indicates which metrics to use. There are two different types of metrics for each metric type: one is a load metric and one is a scaling metric. For example, if the metric type is
ASGCPUUtilization
, the Auto Scaling group's total CPU metric is used as the load metric, and the average CPU metric is used for the scaling metric.Required: Yes
Type: String
Allowed values:
ASGCPUUtilization | ASGNetworkIn | ASGNetworkOut | ALBRequestCount
Update requires: No interruption
ResourceLabel
-
A label that uniquely identifies a specific Application Load Balancer target group from which to determine the total and 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.
