You could enable kernel system accounting (please see sa(8) and
friends). While this is not realtime it may be okay for debugging
purposes. The accounting log provides the command name along with a
number of readings, including the number of disk i/o operations. Please
note that the accounting data is available for logging purposes only
after the respective process terminated.
