Abstract: Techniques for reporting computer resource utilization data involve receiving metrics data relating to a computer system that includes multiple resources and identifying, based on the metrics data, resources that are over-utilized and resources that are under-utilized. A summary graphical report of the number of over-utilized resources and the number of under-utilized resources is generated, and a utilization graphical report is generated. The utilization graphical report includes a color-coded listing of over-utilized resources and under-utilized resources and a color-coded indication of utilization for each resource over multiple time periods including one or more predicted utilizations for a future time period. The summary graphical report is displayed, and the utilization graphical report is displayed using a user interface that supports automated manipulation of information in the graphical report in response to a user interaction.
