FSx for Windows dimensions

FSx for Windows File Server metrics use the FSx namespace and provide metrics for a single dimension, FileSystemId. You can find a file system's ID using the describe-file-systems Amazon CLI command or the DescribeFileSystems API command. A file system ID takes the form of fs-0123456789abcdef0.
