How can I get nginx-rtmp-module stats for all workers?

[Alexander Chekalin]

Hello,

I’ve set up nginx with nginx-rtmp-module as a NGINX-based Media Streaming Server, and it works fine, but now I try to get stats for this server. 

General approach is to use 

location /stat {  rtmp_stat all; }

which produce xml that can be parsed nicely, but my suspicions are that I got stats for one worker random worker on each poll (not accumulated stats for all workers). 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.

Is there any way I can use to get cumulated stats for all workers on host?

Thank you in advance!
