  • Publication number: 20210208945
    Abstract: An information processing apparatus (100) has a ring buffer (113) and a save area (117). A log generation unit (108) generates a log of an application (107) in the ring buffer (113). A resource monitoring unit (109) monitors a current resource-usage amount for the application (107). A rule collation unit (111) determines whether the current resource-usage amount for the application (107) meets a log saving condition that is a condition for saving the log of the application (107). A log saving unit (112) saves, in the save area (117), the log in the ring buffer (113), if the current resource-usage amount for the application (107) is determined by the rule collation unit (111) to meet the log saving condition.
