• OpenShift

Overview

The general technique is to increase the logging level of various OpenShift master (api, controllers) and node processes as described here:

For the master controller process:

journalctl -u atomic-openshift-master-controllers -f

For the node process:

journalctl -u atomic-openshift-node -f
