Internet of things operations monitoring system

An IoT operations monitoring system (100) for monitoring operations of multiple IoT devices (104, 105, 106) in a plurality of target IoT systems (101, 102, 103), the IoT operations monitoring system (100) comprising:

• a plurality of attributes filtering devices (120, 130, 140), arranged to operably receive multiple packet messages (310) corresponding to the multiple IoT devices (104, 105, 106) and generated by one or more packet gateway devices (150, 160, 170), and to operably generate multiple activity records (320, 322, 324, 326) respectively corresponding to the multiple IoT devices (104, 105, 106) according to the multiple packet messages (310);
• and
• a data inspection system (110), comprising:
• a communication circuit (111), arranged to operably communicate data with the plurality of attributes filtering devices (120, 130, 140) through networks to receive the multiple activity records (320, 322, 324, 326) 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.
