      * Before this update, the `node-exporter` collector did not exclude Calico Virtual NICs when collecting network interface metrics. This update adds the `cali[a-f0-9]*` value to the`collector.netclass.ignored-devices` list to ensure that metrics are not collected for Calico Virtual NICs. link:https://issues.redhat.com/browse/OCPBUGS-7282[OCPBUGS-7282]

      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.
