## 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

export JUNIT_OUT ?= $(ARTIFACTS)/junit.xml
export REPO_ROOT := $(shell git rev-parse --show-toplevel)

# Make directories needed by the build system
$(shell mkdir -p $(TARGET_OUT_LINUX))
$(shell mkdir -p $(TARGET_OUT_LINUX)/logs)
$(shell mkdir -p $(dir $(JUNIT_OUT)))

# Need separate target for init:
$(TARGET_OUT):
	@mkdir -p $@

# If the hub is not explicitly set, use default to istio.
HUB ?=istio
ifeq ($(HUB),)

  // Return previous terminated container logs. Defaults to false.
  // +optional
  optional bool previous = 3;

  // A relative time in seconds before the current time from which to show logs. If this value
  // precedes the time a pod was started, only logs since the pod start will be returned.
  // If this value is in the future, no logs will be returned.
