Abstract: Belle II experiment is a next-generation B-factory at KEK in Japan, which will collect 50 ab−1 data sample for 10 years, that corresponds to about 5×1010 B ¯ B-pair events. To handle such a huge data sample, Belle II has adopted the distributing computing. A monitoring system is necessary to operate the computing system stably and we have been developing the monitoring system for Belle II computing based on our experience we have gained through the mass production test of the Monte Carlo simulation events. In this paper, we introduce our monitoring system, especially, the one we call “active-way” monitoring.
