#### 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`

        final JobLogPager pager = copyBeanToNewBean(body, JobLogPager.class);
        final List<JobLog> list = jobLogService.getJobLogList(pager);
