物联网云服务的日志聚类算法研究

Log clustering of the log data of the IoT cloud service to obtain the line patterns of the event logs and the frequencies of them,which can be used in log monitoring and alarm of the cloud platform. LogCluster is a density-based log clustering algorithm. Based on this algorithm, an improved algorithm is proposed. By improving the calling sequence of the heuristic method in the algorithm, the problem that the effective clustering result cannot be output under the high threshold is solved; the outlier judgment logic is improved, and the outlier output is more consistent with the clustering result; At the same time, the optimization algorithm can automatically adjust the threshold for multi-round clustering and output multi-level clustering results. Finally, the experimental results show that the improved algorithm can output more patterns and multi-level clustering results while maintaining similar running time.
