Data transfer monitor system, data transfer monitor method and base system
Transfer of desired monitoring data is enabled while restraining a data storage capacity and transfer capacity. A base system senses an alert and generates an index for specifying collection target data that is data present within a predetermined collection target time including an alert occurrence time point, records the collection target data in association with the index, into a time-series data table, and stores alert identification information in association with the index, into an index specifying table. A center system receives the alert identification information and transmits a data request for requesting the collection target data, to the base system. The base system, upon receipt of the data request, acquires the index associated with the designated alert identification information by searching the index specifying table, acquires the collection target data specified by the index from the time-series data table, and transmits the acquired data to the center system.
