Fault Injection Testing (FIT) is a method for verifying fault tolerance of widely distributed applications. In this paper, by limiting network failures to line disconnections, all FIT scenarios are generated and exhaustive evaluation of fault tolerance is performed. Authors evaluate the visualization method of performance data obtained from this evaluation and the reduction of the fault tolerance evaluation cost by the proposed method., A wide area distributed application is affected by network faults due to natural disasters because the servers on which the application operates are distributed geographically in a wide area.
