    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
}

    fastcgi_pass   test-php:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;

        vhost_traffic_status_bypass_stats on;
        vhost_traffic_status_display_format html;
        allow all;


    }


}

services:
  php:
    container_name: php
    image: php:fpm
    volumes:
      - ./code:/var/www/html/x


  nginx:
    container_name: Nginx
    image: arquivei/nginx-vts:latest
    volumes:
      - ./code:/var/www/html/x.com
      - ./site.conf:/etc/nginx/conf.d/x.conf:ro
    ports:

  prom:

    image: prom/prometheus:latest
    volumes:

  nginx-vts-exporter:
    container_name:  Exporter
    image: sophos/nginx-vts-exporter:latest
    ports:        
     - 9913:9913

this is my prometheus.yml

    evaluation_interval: 15s
scrape_configs:

   static_configs:
    - targets: ['127.0.0.1:9913']

 - job_name: prometheus
   static_configs:
    - targets: ['127.0.0.1:9090']

In your prometheus.yml file, you should use nginx-vts-exporter:9913 instead of 127.0.0.1:9913 as the target for the nginx exporter.Same for the prometheus target. Don't use 127.0.0.1 but the name of the container.

In addition, it looks like you need to configure the nginx exporter to scrape nginx:80 and not localhost to retrieve the status information. You can do that by setting the environment variable NGINX_HOST to http://nging/status/format/json for the nginx-vts-exporter container in your docker-compose file, something like this:

  nginx-vts-exporter:
      container_name:  Exporter
      image: sophos/nginx-vts-exporter:latest
      environment:
        - NGINX_HOST="http://nging/status/format/json"       
      ports:        
       - 9913:9913
