Embodiment Construction
[0035] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] Logs are massive and unstructured. In a distributed IoT environment, the total volume of log messages may exceed tens of millions per day. The log formats provided by different suppliers are different. The diversification of the Internet of Things makes it contain a wide variety of logs, and when different events occur, the generated logs are different. The rating used to identify log events does not accurately indicate the type of event, nor is it directly useful for anomaly detection. The content of the log is complex, and various devices in the system and the network will also generate logs. Prior knowledge is r...
