Fields

Field name Explanation

Avg Service Time Average I/O operation time for the device (seconds).

Avg Wait Time Average I/O waiting time for the device (seconds).

Device Name Device name.

I/O Mbytes Total transfer size of I/O processing (megabytes).

Mbytes Xferd/sec Average I/O speed (megabytes/second).

Queue Length Queue length of devices for which the I/O processing amount per second is 1.

Read Mbytes Transfer size of read processing (megabytes).

Reads/sec Frequency of read processing (number of times per second).

Total I/O Ops Number of times I/O processing occurred.

Total I/O Ops/sec Frequency of I/O processing (number of times per second).

Total Service Time Total operation time for processing for a device (seconds). This value includes the waiting time.
On HP-UX, because this is the sum of the total operation time of all I/O, if processing for a device is executed continuously, the value may greatly exceed the Interval value. With other OSs, if processing for a device is executed continuously, the Interval value may be exceeded.

Write Mbytes Write processing transfer size (megabytes).

Writes/sec Frequency of write processing (number of times per second).
