Description Xingxing Xia 2020-08-21 03:53:47 UTC 
Description of problem:
Now openshift-kube-apiserver and openshift-apiserver pods have a new container called "*-check-endpoints" which is responsible for PodNetworkConnectivityCheck. But `oc get PodNetworkConnectivityCheck -n openshift-apiserver` has no resource.

Version-Release number of selected component (if applicable):
4.6.0-0.nightly-2020-08-21-011653

How reproducible:
Always

Steps to Reproduce:
1. $ oc get PodNetworkConnectivityCheck -n openshift-kube-apiserver
NAME                                                                                             AGE
kube-apiserver-xxia821a-zj9zv-master-0-to-etcd-server-localhost                                  75m
...

$ oc get PodNetworkConnectivityCheck -n openshift-apiserver
No resources found in openshift-apiserver namespace.

Actual results:
1. OAS namespace has none.

Expected results:
1. OAS namespace should have like KAS. As per the slides in MSTR-1036 "Key Network Connections Between openshift-apiserver and ..." and the Description in MSTR-1008 "Network check is wired into openshift-apiserver (MUST)", openshift-apiserver should have too. And https://github.com/openshift/openshift-docs/pull/24927/files says "This resource keeps track of the latest reachable condition, the last 10 successes ..."

Additional info:
Comment 1 Xingxing Xia 2020-08-21 03:55:04 UTC 
Adding "Regression" Keyword because I remember OAS also had when I first looked at the slides of MSTR-1036 and gave a try.
Comment 2 Xingxing Xia 2020-08-21 03:56:05 UTC 
So either it is a functional bug, or a Slides and Doc bug.
