    Good day,

    As much as I understand it:

    Data Disk Read operations/sec

    Average number of Input/output operations per second per disk from a single data disk during monitoring period

    OS Disk Read operations/sec

    Average number of Input/output operations per second per disk from operating system disk during monitoring period

    Disk Read operations/sec

    Average number of Input/output operations per second per disk from disk during monitoring period
