Record diagnostic info about this streaming session. This includes:

- the first 5 data-transport tasks: wall, cpu, queue, page, kernel lock times, plus s2s and e2e;

- the last 25 data-transport tasks: same (s2s / e2e are start-to-start / end-to-end durations);

- the min and max and sum values for the above as well (except s2s and e2e for sum values);

- underruns (read too close to the producer): total count/duration, longest single underrun;

- overruns (read too far ahead of the producer): total count/duration, longest single overrun.
