PDTDELTA Display the IO's used by the Device during the Measurement Period

PDTDELTA [IO >|<|=x] [, INT=n]

Like PDT (see above), the PDTDELTA command displays a list of all generated devices, together with their current status. In addition to the total number of IO's per device, the number of IO's occuring during the last measurement period will also be displayed for each device. The default measurement interval is 10 seconds.

The current size of the IO queue for each device will be displayed in the #-Q column The #-R column will display the size of the Retry queue. This column will only have a value other than 0 if IO errors have occured on the respective device.

IO This parameter will cause only those devices which have used more than (>n), less than (<n) or exactly n IO's (=n) during the measurement period.

INT=n Duration of the measurement period in seconds. Standard: INT=10.

Note:

The same commands and Action Codes as used in the PDT mask can be used in the PDTDELTA mask (see above).
