When operating large-scale IT services, multiple systems need to be managed for the detection of abnormalities. Since the monitoring and control personnel can hardly have all the domain knowledge required for these systems and services, there have been increasing needs for automated models that detect abnormalities by analyzing the characteristics of each service and learning patterns. In this experiment, we use the time-series data in the access log of the web server to examine the capability of the existing spectrum residual method model in detecting the anomalies in real-time, and propose an improved detection model which can respond more quickly to an abnormal situation. Our experiment showed that the proposed model was able to predict abnormal symptoms before actual failure occurs, and to respond in advance. |
