Abstract A method of determining the utiliaztion of the processor, the channel and the disk device using the accounting data is described. Controlled experiments are performed with an IBM 370/155 in a dedicated environment using a software monitor, Configuration Utilization Evaluator (CUE). The accounting data collected by Systems Management Facility (SMF) during these experiments are used to calculate the utilization of the processor, the channel and the disk device. The calculated values compare favourably with those measured by the software monitor.
