The host itself is 4-cores, so I have 4 workers running and I think I got confusing stats since each poll brings me stats for random worker.

Yes, RTMP statistics is only available for a single worker.
For multi-worker statictics there was a patch "per-worker-listener" at

However, this solution is not perfect.
