Can someone enlighten me as to how to get 'iostat -Id' or 'iostat -Idx'
style counters for zpools?
I've read through the man pages, but all I can see is 'zpool iostat' which
gives values which appear to be averaged over an unspecified time period.
With a 30-disk zpool, I can't fathom out how to get any meaningful data
from the individual disk stats, and keeping a daemon running 'zpool iostat
N' just to parse its output seems hugely inefficient and hacky...
Thanks.
