System resource component utilization

Abstract:

A computer implemented method including receiving a set of utilization metrics for a system comprising at least an average number of concurrent requests to the system and a maximum concurrency that the system is capable of supporting, providing a function that incorporates two curve segments, computing a utilization according to a ratio of the average concurrent requests to the function, and managing performance problems indicated by the utilization. A computer implemented method including receiving a set of response time metrics comprising at least an average response time, average concurrent requests, and a minimum interference response time, computing a current response ratio of the minimum interference response time and the average response time, computing a maximum response ratio corresponding to a maximum concurrency, determining the maximum concurrency is inaccurate by comparing the maximum response ratio and the current response ratio, and replacing the maximum concurrency.
