Vitrage is not a monitoring tool. It does not perform statistic calculations, health checks, etc. Instead, it gets topology and alarms from several datasources (OpenStack or external), combines them in a topology graph, and performs RCA analysis on top of the graph. The RCA rules are defined in Vitrage templates [1]. In these templates, you can define topology conditions and actions to be executed as a result, like raise an additional alarm, modify a resource state, or mark root-cause relationship between two alarms.
