Is there a way of getting per process I/O statistics on AIX, i.e. to get current disk I/O rate of a process? Commands like iostat, nmon, topas etc. can't display such data. Filemon also doesn't help. Actually, what I would need is something much like iotop(1) command on Linux.

Update: it seems there is no builtin command(s) to do this. I will most probably make my own by using the SPMI API.

try the following command

ps -ef  -o ruser,pid,ppid=parent,tdiskio

you can play around with the -o switch to display parameters you want and hide others and if required, you can sort the output with one of these commands using sort and awk or cut commands

For some reason TDISKIO field is "-" for all processes displayed. –  ipozgaj Oct 28 '10 at 11:59
