  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.
