# RecommendedOptionProjectedMetric
<a name="API_RecommendedOptionProjectedMetric"></a>

Describes a projected utilization metric of a recommendation option.

**Note**  
The `Cpu` and `Memory` metrics are the only projected utilization metrics returned when you run the [GetEC2RecommendationProjectedMetrics](API_GetEC2RecommendationProjectedMetrics.md) action. Additionally, the `Memory` metric is returned only for resources that have the unified CloudWatch agent installed on them. For more information, see [Enabling Memory Utilization with the CloudWatch Agent](https://docs.amazonaws.cn/compute-optimizer/latest/ug/metrics.html#cw-agent).
