Can you split this up into sections:
- Prometheus setup - configuration - yaml file that is volume mounted. Add a link to the file here and describe how the different sections allow it to do pod discovery.
- Netplugin/Netmaster exporters - How the exporter is a web service providing a /metrics rest end point at different ports for master/netplugin
How the pods themselves are configured with annotations to allow for the data to be fetched. - Exporter implementation - Ruby code details
- OVS details - how there is a server started by netplugin on the port that you access and how it has traffic stats
- Data extraction pipeline - prometheus to exporter to netmaster/ovs pipeline

Neelima can you please expand on what information you're looking for point 4?

For 4. Netplugin uses OpenvSwitch to program the traffic flows. Netplugin starts an ovsdb-server at port 6640. ovsdb stores information about the traffic flows and statistics.
Exporter can access the ovsdb at localhost:6640 as it is running in the same network namespace, as part of the same pod.
