Abstract	For high-precision measurements, all influences, however small, must be taken into account when evaluating the measurement data. Sophisticated analyses must therefore be performed to estimate the measurement uncertainties and determine possible correction factors. In this thesis two analyses were conducted to estimate efficiencies of the Belle II trigger system. The first one is particularly relevant for a measurement which is an important input for the calculation of the theoretical anomalous magnetic moment of the muon. The second is essential for the search for Dark Matter. The Belle II experiment is expected to produce a huge data set of 50 ab −1 within the next years. It will have to be evaluated in years of analyses. In order to record this huge amount of data, it is essential that both the SuperKEKB accelerator and the Belle II detector run smoothly throughout. To prepare the Belle II detector for this task in the coming years, a new unified and centralized logging and monitoring architecture was developed and implemented in this thesis.
