      —
      Description of problem:

      - Calico Virtual NICs should be excluded from node_exporter collector.
- All NICs beginning with cali* should be added to collector.netclass.ignored-devices to ensure that metrics are not collected.

      Version-Release number of selected component (if applicable):

      OpenShift 4.12

      How reproducible:

      Always

      Steps to Reproduce:

      Run an OpenShift cluster using Calico SDN.
Observe -> Metrics -> Run the following PromQL query: "group by(device) (node_network_info)"
Observe that Calico Virtual NICs present.

      Actual results:

      Calico Virtual NICs present in OCP Metrics.

      Expected results:

      Only physical network interfaces should be present.
