Due to the increasing utilization of modern IT service centers, energy consumption has been one of the top concerns for administrators. Many indicators have been proposed with different aims at several levels, but what is missing is an approach for presenting them together within meaningful indexes. The goal of this paper is to introduce our approach to support inter-relationships identification for heterogeneous indicators. The presented aggregation framework aims to make indicators comparable through normalization functions and to properly express the indicator relevance within aggregated values. Thus, the normalization deals with four indicators thresholds and the aggregation calculates the indicator violation impact from the system perspective. The approach is demonstrated with GAMES project testbed measured indicators and presented in a dashboard prototype tool.
