+Iotop watches I/O usage information output by the Linux kernel (requires
 2.6.20 or later) and displays a table of current I/O usage by processes
 or threads on the system. At least the CONFIG_TASK_DELAY_ACCT,
 CONFIG_TASK_IO_ACCOUNTING, CONFIG_TASKSTATS and CONFIG_VM_EVENT_COUNTERS
 options need to be enabled in your Linux kernel build configuration.

+For each process, its I/O priority (class/level) is shown.
 In addition, the total I/O bandwidth read and written during the sampling
 period is displayed at the top of the interface.
+Note that only disk i.e. block and net I/O are provided by the kernel and
