Abstract

In order to change a policy while alarm-monitoring a production environment, during a production-environment operation, a method of controlling a computer system is provided, in which a policy is temporarily changed, thereby performing setting change. An agent transmits a monitoring result based on a first monitoring condition. A management unit generates a second monitoring condition based on a received change request. The agent transmits a monitoring result based on the second monitoring condition. The management unit holds information for correlating the first and second monitoring conditions with each other. Upon reception of a confirmation request for confirming the second monitoring condition, the management unit specifies the first monitoring condition correlated with the second monitoring condition based on the information. The agent which has received the deletion request stops the transmission of the monitoring result based on the first monitoring condition.
