PROBLEM TO BE SOLVED: To provide a resource capacity prediction apparatus that can accurately predict a resource capacity required for an IT service from monitoring information on resources having different monitoring states.SOLUTION: A resource capacity prediction apparatus includes log reliability calculation means 81 and resource usage rate transition estimation means 82. The log reliability calculation means 81 acquires a first log on monitoring states of a resource from a computer, and on the basis of information included in the first log on the monitoring states of the computer at a plurality of times, calculates reliability of the log at the plurality of times. The resource usage rate transition estimation means 82 acquires, from the computer, a second log on usage of the resource and a third log on measurement of a service level item of the computer, and on the basis of information included in the second log on usage rates of the resource of the computer at the plurality of times, information included in the third log on measurement values of the service level item of the computer at the plurality of times, and reliability of the log at the plurality of times, estimates a usage rate of the resource of the computer. |
