+## Target MDG/TF
+
+NBI
+
+## Description
+
+Present API implementation for NS metric collection in NBI(Feature 7270) only fetch NFVI metrics, 
+not the VNF metrics.
+
+NFVI metrics listed as,
+ cpu_utilization
+ average_memory_utilization
+ disk_read_ops
+ disk_write_ops
+ disk_read_bytes
+ disk_write_bytes
+ packets_dropped_<nic number>
+ packets_received
+ packets_sent
+
+Improvising the NBI to fetch both VNF and NFVI metrics from Prometheus as part of the same API.
+
+This can be done by making NBI fetch VNFRs collection from mongodb and get the VNF metric names 
+with that NBI can query Prometheus to get the VNF metrics.
+
+## Demo or definition of done
+
+Working NBI API which will fetch metrics of both NFVI and VNFs.
