When we define a device as a web server with a specific IP address and then created a HTTP Advanced sensor to monitor the loading for a particular web page, we are expecting the sensor will connect to the specified IP address and post the URL defined in the setting. But what we are seeing is that the sensor will resolve the host name in the URL using DNS and then connect to the IP address returned, overide what we have put into the device setting.

This make the sensor useless for us as we cannot nominate which server and/or network path to measure the loading time.

Hi,
as stated in the documentation the HTTP advanced sensor is not dependent on the DNS name/IP address of the parent device. Which means if not explicitly referring to the DNS/IP of the parent device this will be a "normal" HTTP Request including DNS resolving.
To use the IP/DNS name of the parent device, you might have a look at the URL Smart Replacement functionality.
Best regards
