The application provides a multi-source log
root cause analysis method and
system based on a
large model. The method comprises the following steps: multi-source log real-time collection and preprocessing, long connection differentiated log pushing, support for
breakpoint continuation, and log
structured analysis and
semantic enhancement; a
business process template library is constructed, error features are extracted, business processes are matched, and hypotheses are verified by using a
large model through multiple rounds of reasoning, and error types,
root cause descriptions, confidence and suggested operations are output; a dialogue
template library and customer portrait are constructed, personalized guidance dialogue is matched and generated, multi-
modal intelligent guidance is realized through real-time channels and state machines; a feedback optimization module collects indicators and constructs a triple tag
data set, and the model is incrementally fine-tuned. The application realizes cross-component log full-link
root cause positioning, generates dynamic dialogue combined with customer portrait, and continuously improves the accuracy of
error analysis and guidance through closed-
loop optimization, and is suitable for enterprise-level
system operation and maintenance and
customer support in the field of financial technology.
