TERMINAL MONITORING METHOD

PROBLEM TO BE SOLVED: To provide a terminal monitoring method capable of providing monitoring information of a monitoring device to a terminal while reducing update time difference of monitoring information display on each operation screen in the terminal, and decreasing a resource amount of the monitoring device and a communication amount of the network.SOLUTION: A terminal monitoring method includes: an information management step which generates, when a monitoring state with respect to a terminal is changed, monitoring information indicating a monitoring state after the change; a transmission step which transmits the monitoring information generated in the information management step to a launcher part via a network; a storage step which stores that a task execution part is activated and in operation; a receiving step which receives the monitoring information in the luncher part; a supplying step which supplies the monitoring information received in the launcher part to the task execution part when the task execution part is in operation; a displaying step which displays the received monitoring information on an operation screen of the launcher part; and a displaying step which displays the monitoring information supplied from the launcher part on an operation screen of the task execution part.
