One way of simplifying the process of analyzing the performance of resource consolidation managers is to provide methods that can facilitate forming an initial understanding of their general characteristics before proceeding with further statistical evaluations. However, to the best of our knowledge, no such methods were previously proposed in the literature. In this work, we present a visualization tool that fills this gap by applying concepts from computational geometry in a rather unconventional manner. In the proposed method, the performance of a resource consolidation manager is represented using shells of convex hulls on a 2-dimensional plane, which can then be used to generate a preliminary understanding of various methods. We have been using the proposed method in our recent studies on the design, implementation and assessment of resource consolidation management methods. In our experience with the proposed tool, visual representations based on convex hulls prove to be of valuable assistance in providing quick and easy preliminary performance analyses which can later be used to direct the focus of statistical evaluations.
