MySQL Enterprise Monitor 8.0.40 Manual
MySQL Enterprise Monitor User Interface is the web-based interface to the Service Manager. The procedure for starting the Monitor UI is identical for all platforms.
If you installed the Service Manager using a graphical interface, you have the option of launching the Monitor UI on the final installation screen (as long as the check box is checked, which it is by default).
      Otherwise, you can view MySQL Enterprise Monitor User Interface by typing
      https://localhost:
      ("18443" is the default port number, adjust accordingly if you
      altered this configuration), into the address bar of your web
      browser. To see the host name and port to use, check the
      18443/configuration_report.txt file.
    
      Under Microsoft Windows, you can also open the Monitor UI by
      choosing the MySQL menu item and finding the
      MySQL Enterprise Monitor entry. Under this entry, choose
      Start Service Manager.
    
On first start, MySQL Enterprise Service Manager can take some time to start while the services and database initialize.
