### Absolute/Differential Values Explained

The fields in monitor dialog boxes display either absolute or differential values:

- An absolute value indicates the value recorded for a monitor object at a specific polling time.

- A differential value is determined by subtracting the value recorded for a monitor object at the previous polling interval from the value recorded at the current polling interval.

Unless otherwise noted, the fields in this dialog box display differential values.
