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). |
