The Belle II VerteX Detector (VXD) is a 6 layers silicon tracker device that will cope with an unprecedented luminosity of 8 × 10 35 cm − 2 s − 1 achievable by the new SuperKEKB e + e − collider, at the KEK laboratory (Tsukuba, Japan). All environment parameters such as temperature, humidity and radiation levels, must be constantly monitored and under certain conditions action must be promptly taken, such as interlocking the power supply or delivering an abort signal to the SuperKEKB collider. In this contribution we describe the Belle II VXD monitoring system. We also present the first results of the temperature and humidity system commissioned in a Beam Test at DESY in April 2016 and the preliminary results of the radiation monitoring achieved with a prototype system during the first SuperKEKB commissioning phase at KEK in February-June 2016.
