Abstract: Methods and systems for system failure diagnosis and correction include extracting syntactic patterns from a plurality of logs with heterogeneous formats. The syntactic patterns are clustered according to categories of system failure. A single semantically unique pattern is extracted for each category of system failure. The semantically unique patterns are matched to recent log information to detect a corresponding system failure. A corrective action us performed responsive to the detected system failure.

Abstract: A computer-implemented method, system, and computer program product are provided for content aware heterogeneous log pattern comparative analysis. The method includes receiving, by a processor-device, a plurality of heterogeneous logs. The method also includes extracting, by the processor-device, a plurality of log syntactic patterns from the plurality of heterogenous logs. The method additionally includes generating, by the processor-device, latent representation vectors for each of the plurality of log syntactic patterns. The method further includes predicting, by the processor-device, an anomaly from the clustered latent representation vectors. The method also includes controlling an operation of a processor-based machine to react in accordance with the anomaly.

Abstract: A method and system are provided for processing computer log messages for log visualization and log retrieval. The method includes collecting log messages from one or more computer system components, performing a log tokenization process on the log messages to generate tokens, transforming the tokens into log vectors associated with a metric space, performing dimensionality reduction on the metric space to project the metric space into a lower dimensional sub-space, storing similarity distances between respective pairs of the log vectors, and in response to receiving a query associated with a query log message for reducing operational inefficiencies of the one or more computer system components, employing the similarity distances to retrieve one or more similar log messages corresponding to the query log message for reducing the operational inefficiencies of the one or more computer system components.
