On the left side, please select either Alerting for new Alarms, Alerting for new Messages, or Alerting for new ToDos and define the settings as follows.
Note: All alerting options only take effect when the Show in Tray option is enabled in the system settings above; if the tray icon is disabled, there will be no alerting from the Windows GUI.

Play Sound
- Play an audible notification if there are new items to be alerted for.

The Windows GUI connects to the web server running with every PRTG core server installation. It supports saving the configuration for a connection to one or more PRTG web servers. In a full PRTG installation, there is already a connection predefined. Note: For a successful connection, the program versions of Windows GUI and PRTG core server have to match.
Please click the Add button to add a new server connection configuration, or choose an existing Server from the list and click the Edit button to change the settings. Use the Delete button to remove an entry from the list. When opening the Windows GUI, it will automatically re-establish the connection used previously.

Windows GUI PRTG Server Connection Settings
Server IP/DNS name
- Enter the IP address or DNS name of the PRTG web server the Windows GUI will connect to.
- This is the same address or name as defined in the web server settings for the core server. For detailed information please see PRTG Server Administrator (Web Server) section. Please make sure that the set values match.
- Please make sure that the server is reachable (especially when using Network Address Translation (NAT)) and no firewall settings are blocking the connection.
Port
- Enter the port on which the PRTG web server is running.
- This is the same port as defined in the web server settings for the core server. For detailed information please see PRTG Server Administrator (Web Server) section. Please make sure that the set values match.

- This is useful to only view a part of the device tree, which is loaded much faster.
- You can create several connections that only differ in the Root ID value in order to quickly switch between different views within your configuration, choosing different connections from the File Windows menu.
Display Name (optional)
- Optionally enter a name that will be displayed in the Server list.
- If you leave this field blank, the Server IP/DNS name setting will be displayed there.
Click the OK button to save your settings.
In the Tools settings you can define commands that will be available in the Windows Menu and context menu of groups, devices, and sensors. A command to initiate a remote desktop connection is already predefined.
Note: In order for the tool function to work with your Windows version, you may need to run the Windows GUI as administrator.
Please click the Add button to add a new command, or choose an existing one from the list and click the Edit button to change the settings. Use the Delete button to remove an entry from the list.

&& echo.host: %host && echo.message: %message
&& echo.value: %value && echo.type: %type
Then, click an object in the device tree and run the tool from the Tools option in the menu (either Windows or context menu).
