Abstract

A method detects a request higher than the baseline in baseline monitoring and stores the request in an outlier request DB. The method selects a common pattern from requests stored in the outlier request DB, differentiates between a request including the pattern and a request not including the pattern, and monitors them with different baselines as different services.
