## Troubleshooting

### Collecting Logs

#### Using `istioctl`/helm

- Set: `values.global.logging.level="cni:debug,ambient:debug"`
- 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
