We can find the excluded texts in the stern.sh file
$ oc exec migration-log-reader-58dc94fbf8-47hhd cat /usr/bin/stern.sh
kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl exec [POD] -- [COMMAND] instead.
Defaulting container name to color.
Use 'oc describe pod/migration-log-reader-58dc94fbf8-47hhd -n openshift-migration' to see all of the containers in this pod.
#!/bin/bash
CONFIGPATH=/var/cache/sa2kubeconfig/kubeconfig-${KSUFFIX}
stern -l app.kubernetes.io/part-of=openshift-migration \
--color ${STERN_COLOR} \
--exclude-container discovery \
--exclude "watch is too old" \
--exclude "Found new dockercfg secret" \
--exclude "specified default backup location" \
--exclude "needs to be at least 1 backup location" \
--exclude "No backup locations were ready to be verified" \
--exclude "Backup cannot be garbage-collected" \
--exclude "Error checking repository for stale locks" \
--exclude "Backup has expired" \
--exclude "error getting backup storage location" \
--exclude "There is no existing backup storage location set as default" \
--since 5s \
--all-namespaces \
--kubeconfig ${CONFIGPATH} \
We can find the log message in the velero pod, but we cannot find it in the migration-logs pod. So it is effectively excluded
$ oc logs velero-5bb4644844-wkm2x | grep "location set as default" | wc -l

$ oc logs migration-log-reader-58dc94fbf8-47hhd -c plain |grep "location set as default" | wc -l
