# 244271 15-Dec-2012 trociny

Change `iostat -Ix` to display total duration of transactions instead
of average duration, and total busy time instead of %.

This looks more useful when one runs `iostat -Ix` periodically to
collect statistics: e.g. now it is possible to calculate busy %
between two runs subtracting total busy times and dividing per time
period.

Average duration and % busy are still available via `iostat -x`.

# 215786 23-Nov-2010 yar

Clarify a few details about iostat(8) behavior:

- The default repeat count for iostat(8) is 1 unless there
was a -w on the command line.

- A -x display doesn't include TTY or CPU stats by default
but they can be turned on with a -T or -C, respectively.

Fixed segfault when more then four devices are specified (improper free),
fixed variable so all manually-specified devices are shown rather then
cutting the display off at 3, fixed formatting for msps when msps is
larger then 100 (it was blowing the columner display output before),
added -K option to make blk count (-oIK) force a 1K block size (to conform
more closely to systat, vmstat definition of blocksize).
