Should be fixed by https://github.com/openshift/console/pull/6775 Checked on ocp 4.6 cluster with payload 4.6.0-0.nightly-2020-10-08-182439.
1. Create a cni NetworkAttachmentDefinition for a project:
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
name: ipvlan-host-local
spec:
config: '{
"cniVersion": "0.3.1",
"name": "ipvlan-host-local",
"master": "ens5",
"type": "ipvlan",
"ipam": {
"type": "host-local",
"subnet": "22.2.2.0/24"
}
}'
2. Create a pod:
apiVersion: v1
kind: Pod
metadata:
name: pod-ipvlan-host-local
annotations:
k8s.v1.cni.cncf.io/networks: ipvlan-host-local
spec:
containers:
- name: pod-name
image: quay.io/openshifttest/multus-pod@sha256:48da37205f9b43424e0983d4c5e7e07f77b7ba1504bbe35e2f264c75dcb4cd15
3. Check the annotation for the pod which contains empty value hereļ¼
$oc get pod pod-ipvlan-host-local -o json|jq .metadata.annotations
annotations:
k8s.v1.cni.cncf.io/network-status: |-
[{
"name": ""
Check the network in/out chart, they show correct charts for current interface.
After update "name" value in above pod annotations, eg, update to "name": "test", "name":"prozyp/ipvlan-host-local-test".
The interfaces in tooltips still contains the interfaces with old names. Wait for more than half an hour, one of the old interface name disappeared. These old interface names should not show in tooltip for later timepoint. Pls refer to attachments. Assigned back the bug.

Data for the charts are fetched from Prometheus, we dont look at pod specs. Please compare the chart with prometheus data. If Prometheus data are not updated correctly, its probably a Networking issue, not UI. According to Comment 7, prometheus data shows the old name, so move the bug to Verified. And will check prometheus data issue with other component team members later. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (OpenShift Container Platform 4.6 GA Images), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2020:4196 |
Created attachment 1716253 [details] networkin-chart Description of problem: Create a pod with multiple network interface, check network in/out charts on the pod detail page, the data are not precise. Version-Release number of selected component (if applicable): 4.6.0-0.nightly-2020-09-23-022756 How reproducible: Always Steps to Reproduce: 1.Create a pod with multiple network interface in project. $ cat ipvlan-host-local.yaml apiVersion: "k8s.cni.cncf.io/v1" kind: NetworkAttachmentDefinition metadata: name: ipvlan-host-local spec: config: '{ "cniVersion": "0.3.1", "name": "ipvlan-host-local", "master": "ens5", // this needs to be updated per cluster, ssh node -- ip route "type": "ipvlan", "ipam": { "type": "host-local", "subnet": "22.2.2.0/24" } }' $ cat pod_multi_interface.yaml apiVersion: v1 kind: Pod metadata: name: pod-ipvlan-host-local annotations: k8s.v1.cni.cncf.io/networks: ipvlan-host-local spec: containers: - name: pod-name image: quay.io/openshifttest/multus-pod@sha256:48da37205f9b43424e0983d4c5e7e07f77b7ba1504bbe35e2f264c75dcb4cd15 After created pod, check the annotation ofpod: annotations: k8s.v1.cni.cncf.io/network-status: |- [{ "name": "testtest", <= add a name make sure not empty 2.Check pod network out/in charts 3. Actual results: 2. The sum of data for each interface are not exactly equal to the total number. Refer to attachments. Expected results: 2. The data should be correct. Additional info:
