PROBLEM TO BE SOLVED: To flexibly hold event information, in a composite event delivery system, a composite event processing apparatus, a composite event processing method and a composite event processing program.SOLUTION: The composite event processing apparatus 11 includes a composite event detection unit 111, a received event history management unit 112, and a virtual storage management unit 113. The composite event detection unit retains a composite event conditional expression, performs matching with a received event, and calls an API prepared by the received event history management unit. The received event history management unit retains, reads and replaces the received event with respect to a storage area of its own node or a storage area of the other node. The virtual storage management unit in the other node provides processing for retaining, reading and replacing an event to the received event history management unit, and retains, reads and replaces the event when called by the received event history management unit. |
