           ========== =====================================================
 
+Barometer is the project that renames Software Fastpath service Quality Metrics
+(SFQM) and updates its scope which was networking centric.
+
+The goal of SFQM was to develop the utilities and libraries in DPDK to
+support:
+
+* Measuring Telco Traffic and Performance KPIs. Including:
+
+  * Packet Delay Variation (by enabling TX and RX time stamping).
+  * Packet loss (by exposing extended NIC stats).
+
+* Performance Monitoring of the DPDK interfaces (by exposing
+  extended NIC stats + collectd Plugin).
+* Detecting and reporting violations that can be consumed by VNFs
+  and higher level management systems (through DPDK Keep Alive).
 
-Table of Contents:
-==================
+With Barometer the scope is extended to monitoring the NFVI. The ability to
+monitor the Network Function Virtualization Infrastructure (NFVI) where VNFs
+are in operation will be a key part of Service Assurance within an NFV
+environment, in order to enforce SLAs or to detect violations, faults or
+degradation in the performance of NFVI resources so that events and relevant
+metrics are reported to higher level fault management systems.
+If physical appliances are going to be replaced by virtualized appliances
+the service levels, manageability and service assurance needs to remain
+consistent or improve on what is available today. As such, the NFVI needs to
+support the ability to monitor:
+
+* Traffic monitoring and performance monitoring of the components that provide
+  networking functionality to the VNF, including: physical interfaces, virtual
+  switch interfaces and flows, as well as the virtual interfaces themselves and
+  their status, etc.
+* Platform monitoring including: CPU, memory, load, cache, themals, fan speeds,
+  voltages and machine check exceptions, etc.
+
+All of the statistics and events gathered must be collected in-service and must
+be capable of being reported by standard Telco mechanisms (e.g. SNMP), for
+potential enforcement or correction actions. In addition, this information
+could be fed to analytics systems to enable failure prediction, and can also be
+used for intelligent workload placement.
+
+All developed features will be upstreamed to Open Source projects relevant to
+telemetry such as `collectd`_, and relevant Openstack projects.
