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
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
ps vx
pgin column is the number of disk I/Os resulting from references by the process to pages not loaded in core
