In a cloud environment that provides both virtual environment and non-virtual environment, in order to address a problem in that monitoring items that vary depending on usage cases must be managed, the present invention proposes a management method in which whether each server brings about a virtual environment or a non-virtual environment is managed by performing registration processing in cooperation with image management and a service resource registration task. In addition, user manager monitoring profile item management information for virtual/no-virtual environment is prepared, and with reference to this information, calculation methods, which specify monitoring items to be monitored out of monitoring items and infra monitoring items for each environment, are managed. With the use of these calculation methods, a user manager and an infrastructure manager may perform optimal monitorings.
