  1. Make sure HttpStubStatusModule is compiled by typing below command in terminal (check for / with – http_stub_status_module):

    nginx -V 2>&1 | grep -o with-http_stub_status_module

  2. Add the following lines to your /etc/nginx/nginx.conf file[OR /etc/nginx/sites-available/default file] within a server { } block :

    server {

    location /nginx_status {

    # Turn on nginx stats

    stub_status on;

    access_log off;

    # Security: Only allow access from IP #


    deny all;



    • Replace IP address with your server’s public IP address. This will allow the status to be accessed from the URL http://yourserver:port/nginx_status.
    • For security, status should only be accessed from the server itself.
    • To access status from another IP as well, you also need to add that IP address in allow list. For example :

      • allow;
      • allow;
  3. Restart the Nginx Web Server after saving changes.
  4. Check in your browser or with curl/wget :

  5. Edit the rptmonitor/config.cfg file:

    • Uncomment the line containing ‘nginx_status_url:‘ & replace your IP & port. For eg. if your IP was and port 80 (– specify the port if default is not 80) then it would be:

    • Provide username(nginx_usrnm) & password(nginx_pswd) if the status URL is protected. Remove # symbol to uncomment the lines.
  6. Restart rptmonitor :

    • For (deb/rpm)package supported Linux distros :

      sudo /etc/init.d/rptmonitor restart
    • For openSUSE(11.4+) with systemd :

      sudo systemctl restart rptmonitor.service
    • For other Linux distro, FreeBSD8+, Mac OS X+ :
