A detection apparatus includes first and second calculating units and a storing unit. The first calculating unit calculates, when a configuration of a system is changed or the like and a combination of messages occurs, a ratio of the number of occurrences of an event at time points corresponding to a time of occurrence of the combination to the number of occurrences of the combination. The second calculating unit calculates an indicator to determine whether the combination of the messages is used to detect occurrence of the event or to detect a sign of occurrence of the event, based on the ratio and on the number of occurrences of the event. When the indicator indicates that a condition is satisfied, the storing unit stores the combination of the messages as a combination used to detect occurrence of the event or to detect the sign of occurrence of the event.

A resource lending control apparatus stores an assignment time and a deletion time in association with each other for each customer. The assignment time indicates a time for assigning an application used by each customer to provide a service to a server. The deletion time indicates a time for deleting the application from the server. The resource lending control apparatus calculates a lendable period of a remaining fixed resource of a lending customer by subtracting the deletion time and the assignment time of the lending customer from a remaining fixed period. The resource lending control apparatus calculates a total borrowing period, i.e., a period during which a borrowing customer is to use a borrowed resource, by adding the deletion time and the assignment time of the borrowing customer to a borrowing request period. Then, the resource lending control apparatus determines whether the calculated total borrowing period is covered by the calculated lendable period to determine to lend the remaining fixed resource.

When searching for a starting point candidate on an abnormality occurred in a first management range, if a search destination extends over a second management range, a first search device transmits a query to a second search device and requests a second search device to search for a starting point of an abnormality in the second management range. The second search device receives the query, searches the second management range for a starting point candidate of an abnormality, replaces a starting point candidate of an abnormality with a dummy configuration item, and transmits a response. Thus, the first search device can search for a starting point candidate of an abnormality without grasping a connection relationship of configuration items in the second management range.
