|
|
You can enable [tracing](/docs/tasks/telemetry/distributed-tracing/) to determine the flow of a request in Istio.
|
|
|
|
Additionally, you can use the following commands to know more about the state of the mesh:
|
|
|
|
* `istioctl proxy-config`: Retrieve information about proxy configuration when running in Kubernetes:
|
|
|
|
{{< text plain >}}
|
|
# Retrieve information about bootstrap configuration for the Envoy instance in the specified pod.
|
|
$ istioctl proxy-config bootstrap productpage-v1-bb8d5cbc7-k7qbm
|
|
|
|
# Retrieve information about cluster configuration for the Envoy instance in the specified pod.
|
|
$ istioctl proxy-config cluster productpage-v1-bb8d5cbc7-k7qbm
|
|
|
|
# Retrieve information about listener configuration for the Envoy instance in the specified pod.
|
|
$ istioctl proxy-config listener productpage-v1-bb8d5cbc7-k7qbm
|
|
|
|
# Retrieve information about route configuration for the Envoy instance in the specified pod.
|
|
$ istioctl proxy-config route productpage-v1-bb8d5cbc7-k7qbm
|
|
|
|
# Retrieve information about endpoint configuration for the Envoy instance in the specified pod.
|
|
$ istioctl proxy-config endpoints productpage-v1-bb8d5cbc7-k7qbm
|
|
|
|
# Try the following to discover more proxy-config commands
|
|
$ istioctl proxy-config --help
|
|
{{< /text >}}
|
|
|
|
* `kubectl get`: Gets information about different resources in the mesh along with routing configuration:
|
|
|
|
{{< text plain >}}
|
|
# List all virtual services
|
|
$ kubectl get virtualservices
|
|
{{< /text >}}
|
|
|
|
* Mixer access logs: Mixer writes access logs that contain information about requests. You can get them with:
|
|
|
|
{{< text plain >}}
|
|
# Fill <istio namespace> with the namespace of your istio mesh. Ex: istio-system
|
|
$ TELEMETRY_POD=`kubectl get po -n <istio namespace> | grep istio-telemetry | awk '{print $1;}'`
|
|
$ kubectl logs $TELEMETRY_POD -c mixer -n istio-system | grep accesslog
|
