The embodiment of the invention provides a problem positioning method and device for a distributed system, equipment and a storage medium, and relates to the technical field of computers. The method comprises the steps that when a target service node reports an error, an error report log corresponding to the target service node is extracted, and the error report log comprises a TraceID; acquiring upstream and downstream logs associated with the TraceID from a log acquisition system, wherein each of the upstream and downstream logs comprises the TraceID, log data and node environment data; and inputting the error log, the upstream and downstream logs and a preset prompt word into the large model to construct a topological graph of the service call chain based on the log data through the large model under the guidance of the prompt word, identify a target error mode of the fault based on the error log, and identify a fault of the fault based on the target error mode, the topological graph and the node environment data. And determining a target root cause of the fault. Therefore, the upstream and downstream logs are associated through the TraceID, and intelligent generation of the root cause is realized by using a large model agent, so that the problem positioning efficiency and the positioning accuracy are improved.

The application provides a problem positioning method and device based on log analysis, equipment, medium and product, relates to the technical field of big data, and specifically relates to the technical field of artificial intelligence and big data. The method comprises the following steps: in response to detecting an abnormal event, acquiring log data; obtaining a plurality of log records with the same call chain identifier in the log data; the call chain identifier is used for associating log records generated when the same business request flows between different service groups; generating a root cause hypothesis based on the time sequence and semantic relationship between the plurality of log records through a target model; the root cause hypothesis represents the problem position and reason causing the abnormal event.
