The evolution of large high speed data processing systems created system performance problems that were difficult to solve because of a lack of the necessary tools with which to gather the required data needed to understand the problem. The high cost of these systems also created a need to monitor the activities of the system resources in order to determine their utilization. In many situations it became necessary to better understand the statistical interaction between the hardware and software during data processing operations before performance problems could be addressed. Monitoring capability was also required to detect and identify design problems and to verify system performance projections without interfering, degrading or affecting the system under surveillance.
