The invention discloses a
root cause speculation method and device based on host state abnormity, equipment and a medium. Comprising the following steps: receiving an abnormal alarm notification of a target host
system, and analyzing to obtain structured alarm data containing a host identifier and an alarm item; matching abnormal components in the
relational database, generating a fault associated component
list according to upstream and downstream components, and extracting a target host
system architecture topological relation; calling a monitoring interface and a
configuration management database system to collect real-time operation data of the
list component, and generating semantic real-time state data in combination with a
semantic mapping template; searching a preliminary historical case based on the alarm item, and generating case data sorted according to the matching degree in combination with
user feedback; and performing multi-
modal processing on the data, inputting the data into a large language reasoning model, outputting a
root cause speculation result sorted according to probability, and displaying the
root cause speculation result on a user
interaction interface. According to the method, rapid and accurate root cause positioning of the abnormal state fault of the
complex system host is realized, the operation and maintenance efficiency is improved, and the service loss is reduced.
