What is diskIOBusyTime?
This read-only 64-bit counter tracks the cumulative time, in microseconds, this disk has spent busy servicing I/O requests since the host last booted. Admins use it to calculate disk utilization percentage over any arbitrary polling interval by comparing the change in diskIOBusyTime to the elapsed wall-clock time, giving a more precise utilization figure than the coarser diskIOLA1, LA5, and LA15 percentages. Dividing the change in diskIOBusyTime by the elapsed time between two polls, expressed as a percentage, gives the admin a precise disk-busy utilization figure for that specific interval.
