Constructing quality metrics for IT infrastructure components using the nonparametric statistics

Rolik O.I., Mozharovskyy P.F., Vovk V.M., Zaharov D.S.

Method for aggregating quality metrics of IT-infrastructure component functioning estimation is proposed. Method uses graph-based presentation of IT-infrastructure in the IT-infrastructure control system and nonparametric statistics, what enables aggregating parameters having different types and influence on the quality of component functioning in generalized indicators. Method sequence, performance estimates and application examples are given, algorithmization and programming issues are considered. Application of the proposed method for metric aggregation allows controlling quality of IT-infrastructure component functioning and reacting timely on components state change.
