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 measures its performance with the SpeedTest Custom tool and records all test results on the server for analysis. Sonar tool using a mini computer such as the Raspberry Pi called SonarBot, in addition to being quite portable, it also allows more performance data samples to be collected so that the accuracy of performance measurements becomes more accurate.
