Aspects of the disclosure provide for a method. In at least some examples, the method includes receiving logs of a computer system, wherein a log comprises information regarding an operation of the computer system. The method also includes performing a course analysis of the logs to identify invariants, parameters, and gray area terms included in the logs, wherein gray area terms are terms included in the logs that are undefined between identifications of invariant or parameter by the course analysis. The method also includes performing a fine analysis to identify each of the gray area terms as either an invariant or a parameter to generate first log parsing templates, wherein the fine analysis is a sequence labeling analysis. The method also includes performing a similarity analysis to combine similar templates from among the first log parsing templates to form second log templates.
