and IOPS. The logs share a common format, which looks like this:
*time* (`msec`), *value*, *data direction*, *block size* (`bytes`),
- *offset* (`bytes`)
+ *offset* (`bytes`), *command priority*
*Time* for the log entry is always in milliseconds. The *value* logged depends
on the type of log, it will be one of the following:
from the start of the file for that particular I/O. The logging of the offset can be
toggled with :option:`log_offset`.
+*Command priority* is 0 for normal priority and 1 for high priority. This is controlled
+by the ioengine specific :option:`cmdprio_percentage`.
+
Fio defaults to logging every individual I/O but when windowed logging is set
through :option:`log_avg_msec`, either the average (by default) or the maximum
(:option:`log_max_value` is set) *value* seen over the specified period of time
