The Belle II experiment has just started, searching for physics beyond the Standard Model in $B$, charm and $tau$ decays using data with the integrated luminosity goal of $50 ~mathrm{ab}^{-1}$. Before the physics run with full detector system being installed, Belle II Phase 2 run is on-going at the time of the conference, until July 2018. In this presentation, we describe the environmental monitoring system with an emphasis on the software tools to help the experts and the non-expert shifters who operate the experiment. The monitoring tools are prepared on the control room especially for the shift-takers. It consists of thre components: the monitoring GUI, the alarm system, and the archiver. The monitoring GUI shows the current state of the detector and the alarm system generate warning states from monitored variables with sound and email notification. The archiver is collecting data on single server and provide collected data to the experimental collaborators.
