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.
