A performance information visualization apparatus includes a memory and a processor. The memory configured to stores, as node information, information that indicates a connection relationship of a node, and information that indicates a generation in which the node is added to an information processing system and a generation in which the node is deleted from the information processing system. The processor configured to that synthesizes configuration information by, when an event occurrence node where an event has occurred does not exist in configuration information of a specific generation associated with a time when the event has occurred and the event occurrence node is added to the configuration information, adding a node and connection between nodes including a connection relationship of the event occurrence node, based on the node information.
