Claim 10:
11. A non-transitory storage medium storing a program that causes a log analysis device to perform:
receiving a plurality of logs from an electronic control system mounted in a movable object, each log indicating status of the electronic control system mounted in the movable object;
analyzing an abnormality in the electronic control system by using the plurality of logs received;
determining a power supply status of the movable object as one of: the power supply status of the movable object is in an OFF state; an accessory power supply of the movable object is in an ON state; and an ignition power supply of the movable object is in an ON state;
depending on a result of the analyzing of the plurality of logs, determining, on a log-by-log basis, a priority of each subsequent log of a plurality of subsequent logs for the electronic control system to transmit, the priority of each subsequent log of the plurality of subsequent logs being determined according to a change in the determined power supply status of the movable object;
generating instruction information that provides an instruction for, based on the result of the analyzing of the plurality of logs and based on the determined priority, controlling transmission of each subsequent log; and
transmitting the instruction information to the electronic control system;
wherein:
the log analysis device is provided outside the movable object and wirelessly communicates with the electronic control systems of the movable object; and
the plurality of logs and the plurality of subsequent logs each include a log recording a dynamic status that is constantly changing in relation to the electronic control system and a log recording a static status that is unchanging in relation to the electronic control system.
