In the result, emphasis was placed on the so-called offline analysis of metrics and online analysis of metrics (e.g. in the form of detection of suspicious values, in real time). Offline data analysis is implemented as a perfaide tool, which provides a command-line interface for, e.g.: (1) trend analysis, (2) automatic creation of configurations, (3) automatic creation of visualizations, or (4) correlation analysis among the monitored metrics. Online data analysis is implemented as a plugin of the Elasticsearch platform called perfcheck. The plugin form of the Elasticsearch was chosen for its ability to process individual records of the current state of metrics before saving them to the internal Elasticsearch database, and at the same time for the possibility of its close integration within the V001 result. The plugin includes a set of deviation detection methods as well as heuristics for filtering out the part of the report that is not satisfactorily informative for the user.
