+
+The scope of the [Barometer]_ project is to provide interfaces to support
+monitoring of the NFVI. The project has plugins for telemetry frameworks
+to enable the collection of platform stats and events and relay gathered
+information to fault management applications or the VIM. The scope is
+limited to collecting/gathering the events and stats and relaying them
+to a relevant endpoint.
+
+The consumption of performance and traffic-related information/events
+provided by this project should be a logical extension of any existing
+VNF/NFVI monitoring framework.
+
+Problem Description
+===================
+
+Integration of Barometer in TripleO is a benefit for building the OPNFV platform.
+The Barometer project is complementary to the Doctor project to build the fault
+management framework with [Apex_Installer]_ installer which is an OPNFV installation and
+deployment tool based on TripleO.
+
