Once NetObserv components are installed on Dataplane nodes, events are reported back to Loki / Prometheus. The reported events are not "enriched" (only basic information like the names of interfaces, MACs, IP addresses is available) with OpenStack metadata.

The Epic proposes to extend the flowpipeline-logs and its RHOSO Dataplane nodes' configuration so that additional topology metadata is attached to the reported events, such as:

• Nova VM names;
• Neutron port names;
• Neutron subnet / network names;
• Keystone project names.

(The list is not exhaustive. The list will need to be clarified with PM and other stakeholders.)

Once this Epic is complete,

• flowpipeline-logs will support a new add_openstack transform rule;
• the component on Dataplane nodes will be configured to pull the relevant metadata from external databases (OVN; maybe OpenStack - though probably not) and attach it to reported events;
• OpenStack traffic events in OCP NetObserv Dashboard will contain additional metadata with VM, port, network, project names etc.
• It will be possible to enable these columns in the Dashboard and see them in UI as needed.

Note: this Epic will add metadata that may be useful to build custom topology view for OpenStack that would be native to OCP Dashboard. While this will become possible, such a view is out of scope for this Epic and will be proposed elsewhere.
