// When you choose a load metric, make sure that the required Sum and Average

// mode (forecast and scale or forecast only), and the desired behavior when
// the forecast capacity exceeds the maximum capacity of the resource. With
// predictive scaling, AWS Auto Scaling generates forecasts with traffic predictions
// for the two days ahead and schedules scaling actions that proactively add

//
// We recommend waiting a minimum of 24 hours after creating an Auto Scaling

// of historical data to generate a forecast.
