  • Publication number: 20190065337
    Abstract: An apparatus calculates a load index for each of a plurality of log collection target devices, based on a log generation time taken for log generation in each of the plurality of log collection target devices and a log transmission time taken for log transmission from each of the plurality of the log collection target devices, and identifies a plurality of log transmittable time ranges of the plurality of log collection target devices, based on the calculated load index. The apparatus determines an order of log transmission of the plurality of log collection target devices, based on the identified plurality of log transmittable time ranges, and determines, based on the order and the plurality of log transmittable time ranges of the plurality of log collection target devices, respective times at which the plurality of log collection target devices execute the log transmission process.
