NGINX

Monitor active connections, connection states, and request rates from the local NGINX server. The agent probes the NGINX stub status module exposed on localhost. You need to enable and configure the stub_status directive for the collector to work.

Configuration

Add a small site configuration to expose NGINX statistics locally:

server {
    listen 127.0.0.1:80;
    listen [::1]:80;

    location /nginx_status {
        stub_status on;
        allow 127.0.0.1;
        allow ::1;
        deny all;
    }
}

Restart NGINX after adding this file. The collector will then scrape metrics from http://localhost/nginx_status.
