In large-scale online service system, to enhance the quality of services, engineers need collect various monitoring data and write many rules trigger alerts. However, number alerts is way more than what on-call can properly investigate. Thus, in practice, are classified into several priority levels using manual rules, primarily focus on handling with highest level (i.e., severe alerts). Unfortunately, due complex dynamic nature this rule-based approach results missed or wasted...
