Supported RAM usage CW metrics for Compute Optimizer

Follow this documents https://docs.aws.amazon.com/compute-optimizer/latest/ug/metrics.html#cw-agent, metric Available MBytes is recommended for RAM usage for Windows instances. Currently, i set up only metrics Memory % Committed Bytes In Use for my Windows instances. I want to make sure that it still accepted for Compute Optimizer recommendation. Or i have to reconfigure CW agent with Available MBytes metrics?
