Comment 2 Junqi Zhao 2018-11-30 05:33:11 UTC

Important

Network utilization metrics for OpenShift Container Platform are only collected for eth0 network interfaces. Therefore, network utilization trend will not be displayed for network interfaces other than eth0 on the overview screen of the provider.

Comment 3 Frederic Branczyk 2018-11-30 07:27:06 UTC

Thank you for reporting this, we should make this configurable. From the description is sounds like the data may be collected though, just not alerted on. Can you validate this by checking whether this query shows records you expected?

https://github.com/openshift/cluster-monitoring-operator/pull/226 was merged to only exclude virtual interfaces and not whitelist only eth0.
