An information processing device includes a processor configured to observe an actual load measurement value of each of change target components that have a dependency relationship with each other from among a plurality of components arranged in a distributed processing system. The processor is configured to calculate a load prediction value until completion of a change processing of all of the change target components based on the actual load measurement value of each of the change target components. The processor is configured to adjust a transmission interval of a change instruction for instructing start of the change processing to each unchanged change target component that has not started the change processing when the load prediction value exceeds a predetermined threshold value. The processor is configured to transmit the change instruction to each unchanged change target component that has not started the change processing at the adjusted transmission interval.

Information processing device and distributed system

An event processing method includes storing in a storage unit, upon receipt of a control message representing information indicating a type of an event to be an execution condition for a plug-in and information regarding the plug-in, in association with each other, the information indicating the type of the event specified from the received control message and the plug-in, in association with each other. The method also includes executing the plug-in upon receipt of an event message representing the information indicating the type of the event. The plug-in being stored in the storage unit in association with the information indicating the type of the event specified from the received event message.
