--
-- The @Cpu@ and @Memory@ metrics are the only projected utilization
-- metrics returned when you run this action. Additionally, the @Memory@
-- metric is returned only for resources that have the unified CloudWatch
-- agent installed on them. For more information, see
-- <https://docs.aws.amazon.com/compute-optimizer/latest/ug/metrics.html#cw-agent Enabling Memory Utilization with the CloudWatch Agent>.
