Information systems infrastructure planning based on collected data from monitoring tools

Management of large computer systems and networking environments usually demand huge investments and lot of human resources. It is almost impossible to calculate minimum investments needed to maintain high level of availability and functionality. The gap between needed and acquired investments in equipment and human resources may lead to degraded performance and functionalities. The possibility to use collected data from monitoring tools and to combine them with inventory data of the same equipment can become an essential analysis tool for the system owners and/or maintainers. A model is presented in this paper, with which current status of an system can be determined based on the age and utilization of the system, as needed and sufficient factors. Presented approach can be used for complex systems, as well as for simple - single product systems.
