Description: The paper considers the possibility of using Shewhart control charts to detect anomalous behavior of the computer system. A software model that was developed creates the templates` base of the computer system`s states based on Shewhart control charts (SCC). It fixes abnormal behavior of the computer system by the pattern matching. This article also contains analysis of the simulation results.
Keywords: computer systems, simulation model, maps Shewhart, external influences on the computer system
