+ Disk utilization: Disk name, Read ios, write ios,
+ Read merges, write merges,
+ Read ticks, write ticks,
+ Read in-queue time, write in-queue time,
+ Disk utilization percentage
Additional Info (dependant on continue_on_error, default off): total # errors, first error code
Additional Info (dependant on description being set): Text description
which is the Xth percentile, and the usec latency associated with it.
+For disk utilization, all disks used by fio are shown. So for each disk
+there will be a disk utilization section.
