For PRTG on premises installations, you can log in to the PRTG web interface once the PRTG core server is installed. In your browser, open the IP address or Domain Name System (DNS) name of the PRTG core server system and click Login. For PRTG Hosted Monitor instances, open your registered PRTG Hosted Monitor domain and log in to the PRTG web interface.

You can look up and change the web server settings of PRTG on premises installations at any time in the PRTG Administration Tool on the PRTG core server system. In particular, when you access PRTG from the internet, you should use a Secure Sockets Layer (SSL)/Transport Layer Security (TLS) secured connection. To secure your connection, click Switch to SSL/TLS under Enable SSL/TLS for the PRTG web interface on the welcome screen.

Load the PRTG Web Interface

In a web browser, enter the IP address or URL of the PRTG core server system. If you use a cluster, connect to the master node. You can also double-click the PRTG Network Monitor desktop icon on the PRTG core server system. If you use PRTG Hosted Monitor, enter the URL of your instance, for example myfirstdomain.my-prtg.com, to access the PRTG web interface with a supported browser.

i_round_redIf you run PRTG on localhost, do not use the DNS name http://localhost to log in to the PRTG web server, as this might considerably slow down the PRTG web interface. Use your local IP address or http://127.0.0.1 instead.

If you see an SSL certificate warning in your browser, you can usually confirm it.
i_square_cyanFor more information, see section SSL Certificate Warning.

The PRTG web interface is your access to PRTG via a web browser. The PRTG web interface is based on Asynchronous JavaScript and XML (AJAX). It uses a responsive design to adjust to the size of your screen.

Use the PRTG web interface as the default interface to set up your monitoring. You can use it to configure devices and sensors, to set up notifications, to review monitoring results, to create reports, and to visualize your monitoring on dashboards.

While you are logged in, the PRTG web interface continuously refreshes the data on the screen via AJAX calls. This way, you are always up to date regarding your monitoring results. You can individually set the refresh interval and method.

With the Single Page Application (SPA) technology, your system stays highly performant because only single page elements are refreshed when necessary.
