Looks like I wasn't clear about what I'm after - sorry.
I want to see how many bytes or KB have been read and written to a given
zpool since creation (as in the newer of uptime or zpool creation) on the
system.
For instance I want this data:
# time iostat -Idx
extended device statistics
device r/i w/i kr/i kw/i wait svc_t %b

For the zpool as a singular entitiy (or even by zfs filesystem), but not
for the individual disks.
Hope this clarifies my request a bit
