Sonar is a tool built to collect data on the results of the performance test which is measured in terms of the end user (user-experience). This tool will simulate the connection process until the user is connected to and measure its performance with the SpeedTest Custom tool and record all test results on the server for analysis. sonar was originally created in the form of a mobile application called SonarApp, a portable screen so that anyone, including a team of technicians, could use a smartphone without having to carry a laptop and other large devices.
