Abstract
A data server includes a controller, a memory that stores first information collected from devices, and master-slave management circuitry that sets whether the data server operates according to one of a master function for managing a data server and a slave function for being managed by the data server. In a case where the master function is set by the master-slave management circuitry, the controller sends to an external client, in response to receiving a data collection request from the external client, information corresponding to the data collection request that is one of data stored in the memory and data received from the other data server. In a case where the slave function is set by the master-slave management circuitry, the controller sends the first information to the other data server in which the master function is set.
