You can confirm whether you have the module enabled with the following command: - -```bash -nginx -V 2>&1 | grep -o with-http_stub_status_module -``` - -If this command returns nothing, you'll need to [enable the `stub_status` -module](https://www.nginx.com/blog/monitoring-nginx/). - -Next, edit your `/etc/nginx/sites-enabled/default` file to include a `location` block with the following, which enables -the `stub_status` page: - -```conf -server { - ... - - location /nginx_status { - stub_status; - } -} -``` - -At this point, your Nginx installation is fully configured and ready for Netdata to monitor it.
