Abstract: A computer system including at least one terminal, a server and a monitoring apparatus. The monitoring apparatus measures first information indicating whether or not a user is present in front of the terminal and transmits measurement results including the first information to the server. The terminal requests the server to start a job as instructed by the user and requests a progress of the job inquired by the user from the server. The server retains second information including the job requested to be started, the user who has requested the job, a count of requests for the progress of the job and the user who has requested the progress of the job, calculates an attention degree of the user for the job based on the transmitted measurement result and the second information, and determines a priority of the job requested to be started based on the calculated attention degree.
