A data-collecting apparatus for collecting, from at least one piece of facility equipment , operation data of the facility equipment, the data-collecting apparatus comprising: a communication unit connectable to a network (NW2b, NW2b') that connects a management apparatus that manages the facility equipment, and the facility equipment; and a data-collecting unit configured to collect, with the communication unit, the operation data from the facility equipment on a basis of a second collection condition (C2), which is different from a first collection condition at a time when the management apparatus collects the operation data from the facility equipment, characterized by : an analyzing unit configured to analyze regularity of first request packets (D1), which are communication packets that are for requesting the operation data and are transmitted to the facility equipment when the management apparatus collects the operation data on a basis of the first collection condition; and a transmission-schedule-determining unit configured to determine a transmission schedule (SS) of a second request packet (D2), which is a communication packet that is for requesting the operation data, and is transmitted to the facility equipment when the data-collecting unit collects the operation data on a basis of the second collection condition, wherein the transmission-schedule-determining unit is configured to determine the transmission schedule (SS) to transmit the second request packet in such a manner that timings at which the first request packets are transmitted are avoided. a communication unit connectable to a network (NW2b, NW2b') that connects a management apparatus that manages the facility equipment, and the facility equipment; and a data-collecting unit configured to collect, with the communication unit, the operation data from the facility equipment on a basis of a second collection condition (C2), which is different from a first collection condition at a time when the management apparatus collects the operation data from the facility equipment, characterized by : an analyzing unit configured to analyze regularity of first request packets (D1), which are communication packets that are for requesting the operation data and are transmitted to the facility equipment when the management apparatus collects the operation data on a basis of the first collection condition; and a transmission-schedule-determining unit configured to determine a transmission schedule (SS) of a second request packet (D2), which is a communication packet that is for requesting the operation data, and is transmitted to the facility equipment when the data-collecting unit collects the operation data on a basis of the second collection condition, wherein the transmission-schedule-determining unit is configured to determine the transmission schedule (SS) to transmit the second request packet in such a manner that timings at which the first request packets are transmitted are avoided. an analyzing unit configured to analyze regularity of first request packets (D1), which are communication packets that are for requesting the operation data and are transmitted to the facility equipment when the management apparatus collects the operation data on a basis of the first collection condition; and a transmission-schedule-determining unit configured to determine a transmission schedule (SS) of a second request packet (D2), which is a communication packet that is for requesting the operation data, and is transmitted to the facility equipment when the data-collecting unit collects the operation data on a basis of the second collection condition, wherein the transmission-schedule-determining unit is configured to determine the transmission schedule (SS) to transmit the second request packet in such a manner that timings at which the first request packets are transmitted are avoided. <EOS>
