    Description

      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.
- node_exporter is meant to collect metrics for physical interfaces only.

      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.

          • Normal - To be worked after urgent and high priorities are resolved. This term is chosen when the severity of an issue is relatively close to the level of effort to fix it. The existence of an easily implemented workaround can also lead to this priority level instead of a higher priority.
