* oc -n openshift-logging apply -f clusterlogforwarder.yaml
* Validate collector pods are healthy
* oc -n openshift-logging get pods
* Forwarding relies on collectors (vector/fluentd depending config).
* Generate a test log line
* oc -n openshift-logging run logger --image=busybox --restart=Never -- /bin/sh -c 'echo hello- forwarding; sleep 5'
* This creates a known message to search in the external endpoint.
* Confirm logs arrive at destination
