The asmiostat.py is nice, but it does not give service times.

Doc ID: 437996.1 ASMIOSTAT Script to collect iostats for ASM disks <-- this one has syntax errors that I am trying to resolve.

I don't know any way to reset these, but there are some tools around which mimic iostat on ASM.
see
https://twiki.cern.ch/twiki/pub/PSSGroup/AsmTools/asmiostat.py.txt or
