Data inspection system for inspecting operating situations of multiple iot devices in a plurality of target iot systems

A data inspection system (110) of an IoT operations monitoring system (100), for inspecting operating situations of multiple IoT devices (104, 105, 106) in a plurality of target IoT systems (101, 102, 103), the data inspection system (110) comprising:

• a communication circuit (111), arranged to operably communicate data with a plurality of attributes filtering devices (120, 130, 140) through networks to receive multiple activity records (320, 322, 324, 326) corresponding to the multiple IoT devices (104, 105, 106) and generated by the plurality of attributes filtering devices (120, 130, 140);
• a storage circuit (113), arranged to operably store the multiple activity records (320, 322, 324, 326) received by the communication circuit (111);
• and
• a data classification circuit (114), coupled with the storage circuit (113), and arranged to operably classify each of the multiple activity records (320, 322, 324, 326) based on contents of N attributes to form M data groups (330, 332, 334), and to operably store the M data groups (330, 332, 334) in the storage circuit (113);
• wherein N is 2 or an integer greater than 2, while M is at least two times of N.
