Provided is a computer system which, by transmitting software to a terminal for updating a control system of the terminal, enables the terminal to properly function based on the software. A computer system configured so as to be able to remotely update software of a terminal, wherein a processor generates an update file for updating the software of the terminal and stores the generated update file in a memory, identifies a specific terminal to which the update file should be transmitted, reads the update file from the memory and transmits the update file from a transmission module to the specific terminal, receives operational information of the update file from the specific terminal via a reception module, and determines whether it is necessary to distribute the update file to a terminal other than the specific terminal based on the operational information.

Computer system, method of updating software with computer system, and program therefor

Provided is a computer system capable of managing the performance of processing upon transmitting software to terminals. The present invention is a computer system comprising a plurality of modules which sequentially execute processing up to transmitting the software to the terminal, a controller which collects an operation log of each of the plurality of modules, and a memory which stores the operation logs collected by the controller, wherein the controller generates an operating performance of a prescribed module among the plurality of modules based on the operation logs stored in the memory.
