ABSTRACT:
In a computer system wherein control of a processor is time multiplexed among more than one system control program, the utilization by a system control program of the processor during a predetermined time interval is determined by accumulating processor idle time for said system control program during said time interval, adjusting the processor idle time accumulated for said system control program by time periods wherein said system control program does not have control of the processor; and subtracting said real idle time from said interval time to obtain CPU busy time.
