Embodiment Construction
[0044] A multi-node web service anomaly detection system, comprising: a metadata collection module, a metadata index module, a web service anomaly detection module and a web service anomaly location module, wherein:
[0045] A. The metadata acquisition module reads the syslog protocol or log text, and obtains the log metadata of the web server of each node in the entire network;
[0046] B. Metadata indexing module: format heterogeneous logs of different types of web servers, unify the data format, and use ElasticSearch technology to index metadata;
[0047] C. Web service anomaly detection module: periodically calculate the error log ratio of each web server node, the same web service is often completed by multiple web server nodes, calculate the average error log ratio of the web service, and build a baseline data model for this ratio , when the current error log ratio of the web service deviates greatly from the error log ratio baseline model of the web service, it is deter...
