The metrics are not exposed to public port, it is expected ot be captured and visualized by other (OpenShift) cluster component.
In tests, it needs to be captured e.g. with kubectl exec command on hub pod, that returns a txt output where lines starting with "konveyor_" should be tested.
Not sure if there needs be some deeper test if metrics were processed by cluster, but that is out of our hands AFAIK.
