Hello! We have some trouble with calculate global traffic...

nginx_vts_server_bytes_total{host="*",direction="out"} 68301879715485

I thought that we have multi master nginx...but not. Only one

# ps aux|grep nginx|grep master
root     13918  0.0  0.3 3627564 451656 ?      Ss   Apr17   3:59 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf

after restart nginx everything is ok...but it's return after few days

Hi, @dolgovas We're sorry for the late response. I'm a new collaborator on this module. So I'd like to work on this issue which active for a long time.

Can you answer a several questions for obtaining some cues about this issue?

1. Can you check your module version? It can be found on your metrics response(json/prometheus) if you use the recent module like this.

   # HELP nginx_vts_info Nginx info
   # TYPE nginx_vts_info gauge
   nginx_vts_info{hostname="foobar",module_version="v0.2.1",version="1.23.1"} 1

2. Is there any nginx.conf which it can be reproduced? We prefer to minimize it excluding your own business logics or nonrelated feature as possible.

3. Does it still reproduce the latest module? If you can check the latest version, please confirm to reproduce.

Hello! Thank you for your answer. Here is module version that we are using now

module_version="0.1.19.dev.91bdb14", version="1.23.1

We meet that bug no so often...

When it comes again, I'll sent you some detailed info
