Document Type and Number:

Japanese Patent JP6190539

Kind Code:

B2

Abstract:

Techniques for extracting a set of highly correlated logs without user's prior knowledge of generation rules of logs generated by a machine. A log analysis apparatus includes: a template storage unit configured to store templates for log messages; a template determination unit configured to determine templates corresponding to log messages provided from a to-be-monitored host from the stored templates; an event candidate extraction unit configured to detect templates determined for log messages provided from the same host from the determined templates and extract a sequence of the detected templates as an event candidate; and an event extraction unit configured to extract a sequence of frequently occurring templates as an event from the extracted event candidate.
