The total wait time of timed other occurrences of the I/O event. The total wait time of timed write occurrences of the I/O event. The total wait time of timed read occurrences of the I/O event. The maximum single wait time of timed occurrences of the I/O event. The average wait time per timed occurrence of the I/O event. The total wait time of timed occurrences of the I/O event. The total number of occurrences of the I/O event. The I/O event name, with the  wait/io/file/  prefix stripped. The  io_global_by_wait_by_latency  and  x$io_global_by_wait_by_latency  views have these columns: These views summarize global I/O consumers to display amount of I/O and time waiting for I/O, grouped by event. By default, rows are sorted by descending total latency. The total number of bytes read and written for the I/O event. The average number of bytes per write for the I/O event. The number of bytes written for the I/O event. The number of write requests for the I/O event. 28.4.3.14 The io_global_by_wait_by_latency and x$io_global_by_wait_by_latency Views
