sdn pods (in "openshift-sdn" namespace) can log some interesting messages, which should be helpful for network troubleshooting. The interesting messages are:
“Got OnEndpointsUpdate for unknown Endpoints” and* “"Got OnEndpointsDelete for unknown Endpoints”:* an event has been received to update some endpoints that don’t exist. It would indicate abnormal access to the API or too slow synchronization with it.
“Unable to update proxy firewall for policy”: SDN has internally requested the update of a policy that has not been found. Kind of a strange scenario, indicating bad or low performant access to API.
“Failed to update proxy firewall for policy: %v, Could not get EgressNetworkPolicies: %v”:
As IO is gathered every 2hrs we want to gather latest occurrences of those errors in logs
