Patent ID: 7756978

Claim:
A multiplicity adjustment system for adjusting a multiplicity of a request to a monitored system, said system comprising: a multiplicity adjustment agent for deciding a multiplicity for each of elements included in said monitored system on the basis of a request to each element; a multiplicity adjustment server for acquiring information relating to the multiplicity of said request from said multiplicity adjustment agent and storing the information as request information for each element; and an integrated multiplicity analysis server comprising a processor and memory for acquiring the stored request information for each element from the multiplicity adjustment server, analyzing the multiplicity of the request for each element on the basis of the acquired request information, and changing the multiplicity of the request for each element according to a result of the analysis; wherein said multiplicity adjustment server acquires a request generation rate indicative of a frequency of request generation per unit time, an average response indicative of an average stay-in time of said request, and a request path indicative of one of elements included in said monitored system through which the request goes, from information about said request; and wherein said integrated multiplicity analysis server calculates a necessary multiplicity in said monitored system on the basis of a critical multiplicity indicative of a limit value of stable running of a server included in said monitored system, a critical CPU time indicative of a CPU time of said server for said critical multiplicity, said request generation rate, said average response, and said request path.
