Abstract: A plurality of process content is retained, said process content including identifiers of a plurality of part content included in each process and information which denotes dependencies among the plurality of part content. When information is inputted which designates a first process and the part content of a problem portion which is included in the first process, a process similar to the first process is retrieved. On the basis of whether there is a change in any of the plurality of part content which is included in the retrieved process, an evaluation value of the retrieved process is either incremented or decremented, and the information relating to the plurality of processes is outputted on the basis of the evaluation value.

Abstract: In performance estimation when the configuration of a computer system is changed, the influence, on performance, of a temporary increase in load to a computer system due to reallocation of a process request allocated to a degenerated server to another server as a result of server degeneration is taken into consideration. In an embodiment, an information processing device which evaluates the performance of the computer system estimates the performance of the computer system when operation of a server included in the computer system is stopped based on the throughput required for the server at the time of operation stop and outputs the estimated performance of the computer system.
