Method for measuring server performance, system for measuring server performance and computer programs therefor

A server performance measurement system for operating a business application in at least one of a plurality of servers to measure performance of the server, including

• a plurality of servers, a load balancer for suitably distributing loads of the plurality of servers, a management server computer for providing information necessary for measurement of performance of the server and recording result of the measurement to be managed, and a load control server computer for controlling the load of the server to implement measurement of performance of the server, which are connected to one another in a mutually communicatable state, wherein
• the management server computer comprises:
• start/end information processing means for transmitting information necessary for start or end of the measurement of performance of the server;
• setting control means for extracting necessary information from a database in which information concerning the plurality of servers and the load balancer is stored and preparing information for setting the server and the load balancer to be transmitted to the server and the load balancer in order to measure performance of the server on the basis of the information necessary for start or end of the measurement transmitted from the start/end information processing means;
• result information processing means for successively obtaining information concerning result of the measurement of performance of the server, transmitted from the load control server computer and judging end time of the measurement on the basis of the obtained information to notify information concerning the end time to the start/end information processing means;
• and
• result information management means for relating the information concerning the result obtained by the result information processing means to the business application operated in the server, storing the information in a database, and managing the information in a database.

A computer program for causing a computer to function as the following means, comprising:

• start/end information processing means for transmitting information necessary for start or end of measurement of performance of at least one of a plurality of servers;
• setting control means for extracting necessary information from a database on the basis of the information necessary for start or end of the measurement transmitted from the start/end information processing means, preparing information for setting a load balancer for suitably distributing a load of the server after the start or end, and transmitting these information to the server and the load balancer;
• result information processing means for successively obtaining information concerning result of the measurement of performance of the server, judging end time of the measurement from the obtained information, and notifying information concerning the end time to the start/end information processing means;
• and
• result information management means for relating the information concerning the result of the measurement obtained by the result information processing means to the business application operated in the server, and storing to manage in a database.

A computer program for causing a computer to function as the following means, comprising:

• start processing means for extracting information that controls a load of at least one of a plurality of servers, that contains a target load value of the server from a database on the basis of information necessary for start of measurement of performance of the server, and starting the measurement of performance of the server;
• feedback information reception means for receiving feedback information transmitted from the server;
• operation processing means for comparing a load value of the server contained in the feedback information with the target load value of the server to decide whether the load of the server is varied or not, when the load of the server is varied, preparing feedback information rewriting information that contains policy for varying the load of the server to be transmitted, and when the load of the server is not varied, varying the target load value of the server, and transmitting information concerning the result of the measurement of the server;
• and
• feedback information rewriting and transmission means for rewriting the feedback information on the basis of the feedback information rewriting information and transmitting the rewritten feedback information to a load balancer for suitably distributing the load of the server.
