Abstract

In one embodiment, a method for allocating programs to resources suited to operating conditions thereof comprises generating composition management information for a plurality of resources based on management information relating to performance and capacity of each of the resources. The composition management information includes identification information for the resources used by a plurality of programs. The method further comprises searching for and locating the composition management information of a resource identified by the identification information for each of the programs, based on the composition management information of the resources, and generating program information which associates composition management information of each of the programs with the composition management information of the located resource; and outputting information indicating that a resource abnormality has occurred with one of the programs, in cases where the composition management information of the resource which is associated with the program in the program information corresponds to one or more rules for detecting a resource abnormality in the program.
