When we offer connectibility to the Internet, network monitoring is necessary to catch the operation situation of the network. The mainly technique is the operational verification of supplied services and the confirmation of IP reachability, and the evaluation on the real user environment is not performed now. Therefore it was difficult to confirm the point of service failure from a real user. Particularly, it is important to the last hop donated to the user that a lot of cases of the wireless network grasp a communication state from the user side. In this report, we suggest the evaluation method for wireless network condition using Raspberry Pi as a measurement terminal. This method detect a network point of failure in user environment. We report the result that we evaluated the system which we produced experimentally in a small event network.
