How to retrieve `server_requests` metrics?

[seanarnold]

The README mentions the server zone metrics such as nginx_server_requests.

What do I need to do to surface these metrics?

I've enabled vhost_traffic_status_zone and m vhost_traffic_status_filter_by_host on in my settings, and am receiving data like the following:

Is my Nginx config correct or is the issue in my nginx-vts-exporter setup?
