EMC _DiskPerformance_NaviSecCli

@Brandon I'm not sure that your script logic is correct here, as the cli command is only run one time to get the full output of all disks and then post processes it.

Targeting the specific disk name inside the cli command, you are only getting that specific disks metrics, not all disks as the command is run only once.

If you were using the OLD script collection method, then yes it would work as it would run that code of each instance discovered using the disk name inside the CLI command.

P.S. : ensure all your disks are collecting data, as I'm certain your change may have broken collection.
