# AWS::ApplicationAutoScaling::ScalingPolicy PredictiveScalingPredefinedLoadMetric
<a name="aws-properties-applicationautoscaling-scalingpolicy-predictivescalingpredefinedloadmetric"></a>

 Describes a load metric for a predictive scaling policy. 

When returned in the output of `DescribePolicies`, it indicates that a predictive scaling policy uses individually specified load and scaling metrics instead of a metric pair.

The following predefined metrics are available for predictive scaling:
+  `ECSServiceAverageCPUUtilization` 
+  `ECSServiceAverageMemoryUtilization` 
+  `ECSServiceCPUUtilization` 
+  `ECSServiceMemoryUtilization` 
+  `ECSServiceTotalCPUUtilization` 
+  `ECSServiceTotalMemoryUtilization` 
+  `ALBRequestCount` 
+  `ALBRequestCountPerTarget` 
+  `TotalALBRequestCount`
