Policy simulator for analyzing autonomic system management policy of a computer system

摘要

Disclosed here is a simulator for simulating the propriety of each created policy less-expensively and fast in an autonomic management system controlled by a policy. The simulator that analyzes the behavior of the above described autonomic management system that receives information inputs of system configuration, load balance setting, system load conditions, software performance, software's transitional performance, and target autonomic management policy to calculate the system behavior (resource utilization rate, software response time, and system throughput) by giving consideration to the system's transitional behavior at a time, then apply an autonomic management policy to the behavior, determine the system configuration and load balance setting at the next time, and use the new system configuration and load balance setting for the next time simulation.
