Fields

Field nameExplanation
Avg Service TimeAverage I/O operation time for the device (seconds).
Avg Wait TimeAverage I/O waiting time for the device (seconds).
Device NameDevice name.
I/O MbytesTotal transfer size of I/O processing (megabytes).
Mbytes Xferd/secAverage I/O speed (megabytes/second).
Queue LengthQueue length of devices for which the I/O processing amount per second is 1.
Read MbytesTransfer size of read processing (megabytes).
Reads/secFrequency of read processing (number of times per second).
Total I/O OpsNumber of times I/O processing occurred.
Total I/O Ops/secFrequency of I/O processing (number of times per second).
Total Service TimeTotal 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 MbytesWrite processing transfer size (megabytes).
Writes/secFrequency of write processing (number of times per second).
