stub_status newrelic plugin (no replies)

Hello nginx experts,

I wonder how nginx generate the server status by stub_status directive.
I have set several virtual host on single server and I put the several nginx server behind load balancer.

I have 2 questions:
1. does stub_status show difference results between virtual hosts in one server or actually this status report is for whole server, regardless its virtual host?

2. what if I put several server behind load balancer, is it still relevant to single server (shown randomly depend on load balancer) or they can be separated per server? Currently I am using newrelic plugin and the report seems separated, I am not pretty sure if this report is accurate to the respective server or it is just random report based on stub_status accessed by the agent.

thank you for your time and answer.
