- Inspect the pod logs of a `istio-cni` Daemonset pod on a specific node.

#### From a specific node syslog

The CNI plugins are executed by threads in the `kubelet` process.  The CNI plugins logs end up the syslog
under the `kubelet` process. On systems with `journalctl` the following is an example command line

                type: string
              logSeveritySys:
                description: 'LogSeveritySys is the log severity above which logs
                  are sent to the syslog. Set to None for no logging to syslog. [Default:
                  Info]'
                type: string
