AWS::AutoScalingPlans::ScalingPlan CustomizedScalingMetricSpecification
CustomizedScalingMetricSpecification
is a subproperty of TargetTrackingConfiguration that specifies a customized scaling metric for a
target tracking configuration to use with a scaling plan.
To create your customized scaling metric specification:
-
Add values for each required property from CloudWatch. You can use an existing metric, or a new metric that you create. To use your own metric, you must first publish the metric to CloudWatch. For more information, see Publish Custom Metrics in the Amazon CloudWatch User Guide.
-
Choose a metric that changes proportionally with capacity. The value of the metric should increase or decrease in inverse proportion to the number of capacity units. That is, the value of the metric should decrease when capacity increases.
For information about terminology, available metrics, or how to publish new metrics, see Amazon CloudWatch Concepts in the Amazon CloudWatch User Guide.
