A special parameter could indicate to dump to stdout each statistic or each device and exit. It would be good for testing, too.

probably you need some more info, besides this? (system is debian 9 (stretch) updated to latest available)

Names like "total disk read" are an assumption. It would be much much better if the measurement names were discovered from running zpool.

An expert should be able to tell us better about where the great/good/hrm/uh-oh/noooooo times should be split, for the coloring in the vertical axis.
