# PredictiveScalingMetricSpecification


 This structure specifies the metrics and target utilization settings for a predictive scaling policy. 

You must specify either a metric pair, or a load metric and a scaling metric individually. Specifying a metric pair instead of individual metrics provides a simpler way to configure metrics for a scaling policy. You choose the metric pair, and the policy automatically knows the correct sum and average statistics to use for the load metric and the scaling metric.
