This article proposes an algorithm for automatic calculation of total cost of ownership (TCO) and server compute efficiency (ScE) metrics for data centers. The approaches described in the article allow to evaluate the efficiency of the data center. A comparative analysis of data sources is given, and, on its basis, information is presented on the possibility of calculating data center usage metrics. The developed algorithm was finalized to the software. The architecture of the software tool is presented, which allows calculating the TCO and ScE metrics. The results of the experimental application of a software solution are presented, which made it possible to calculate the ScE for a loaded machine and a machine operating in normal mode. And also with the help of the software tool, the results of TCO metric calculation for Dell server are presented.
