System and method for providing the capability to resample computer system metrics, while providing improved accuracy over conventional techniques. The system and method conduct s monitoring and measuring metrics of system resource consumption of a plurality of entities to generate resource consumption data, generating a report of the resource consumption data for the plurality of entities for each of a plurality of time periods, identifying a number, k, of the plurality of entities as top-k consumers of resources for each of the plurality of time periods, identifying at least one residual entity of the plurality of entities whose resource consumption is not included in the top-k entities based on residual resource consumption data of the entity, and resampling the reports of the resource consumption data corresponding to the top-k entities and to the at least one residual entity to form at least one report covering a time period.
