Abstract: A data processing device determines, based on a plurality of logs of a same log type, a log template of the log type (i.e. a parsing rule), and extracts, based on the log template, variables of the plurality of logs to generate a structured log so that the parsing rule does not need to be manually set, and manual maintenance on the parsing rule is not needed. A data processing method includes obtaining a log set; determining that N logs in the log set belong to a first type; determining based on the N logs, a log template corresponding to the first type, where the log template corresponding to the first type is used to indicate a variable location of the N logs; and extracting based on the variable location, variables from one or more logs in the N logs to generate a structured log.
