Storage medium, data collecting device, and data collecting method

A data collecting device comprising:

• a memory;
• and
• circuitry coupled to the memory and configured to
• identify a data obtainment target period and a plurality of areas based on a request from a user,
• extract a plurality of apparatuses present in each area in each time frame as a data obtainment unit of the period,
• assign, for each set of the time frame and the area, an apparatus as a collection source of a data block corresponding to the set of the time frame and the area based on a given condition from among the extracted plurality of apparatuses, and
• collect the data block from the apparatus assigned as the collection source for each set of the time frame and the area.
