[]()[]()[]()[]()

 These views summarize global I/O consumers to display amount of I/O, grouped by file. By default, rows are sorted by descending total I/O (bytes read and written).

 The [`io_global_by_file_by_bytes`](sys-io-global-by-file-by-bytes.html) and [`x$io_global_by_file_by_bytes`](sys-io-global-by-file-by-bytes.html) views have these columns:

* `file`

   The file path name.

* `count_read`

   The total number of read events for the file.

* `total_read`

   The total number of bytes read from the file.

* `avg_read`

   The average number of bytes per read from the file.

* `count_write`

   The total number of write events for the file.

* `total_written`

   The total number of bytes written to the file.

* `avg_write`

   The average number of bytes per write to the file.

* `total`

   The total number of bytes read and written for the file.

* `write_pct`

   The percentage of total bytes of I/O that were writes.
