>Description:
iostat can provide an aggregate number for transactions per second and Bytes per transaction for a given device, but if it is a block device, is there a counter accessible from iostat or elsewhere that I can see how much is read transactions versus write transactions?
>How-To-Repeat:
iostat -K -d -I 1
>Fix:
Don Nelson has provided some patches to add a "Solaris-style -x flag to iostat" that I will attach to this PR shortly.
