A system includes a plurality of client terminals, and a reception service system receiving data from the plurality of client terminals. The reception service system includes a first queue configured to receive data to be a target of predetermined processing, and a second queue configured to receive data not to be a target of the predetermined processing. Each of the plurality of client terminals transmits data relating to an event that occurred in the client terminal, to the second queue based on a second transmission rule for transmission of data to the second queue in a case where it is determined that an amount of data transmitted from the client terminal to the first queue per unit time exceeds a predetermined value.
