nginx monitoring prtg

If you’re merely interested in recording the connection information from the status page, you can use the embedded variables that the status module exposes, and format them for consumption by the HTTP Content sensor directly in the NGINX configuration:

location /prtg {
    return 200 [$connections_active][$connections_reading][$connections_writing][$connections_waiting];
    access_log off;
    allow x.x.x.x/y;
    deny all;
}
