# PredictiveScalingPredefinedMetricPairSpecification
<a name="API_PredictiveScalingPredefinedMetricPairSpecification"></a>

 Represents a metric pair for a predictive scaling policy. 

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