Hi,



Sorry for the late reply, I somehow missed your mail.



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.

Hope it helps,
