#### GKE via Stackdriver Log Viewer

Each GKE cluster's will have many categories of logs collected by Stackdriver.  Logs can be monitored via
the project's [log viewer](https://cloud.google.com/logging/docs/view/overview) and/or the `gcloud logging read`

- Introduced new metrics removing the redundant subsystem in kube-apiserver pod logs metrics and deprecate the original ones:
  - kube_apiserver_pod_logs_pods_logs_backend_tls_failure_total becomes kube_apiserver_pod_logs_backend_tls_failure_total
