How to figure out what happened to a request in Istio? 80

You can enable 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 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 {{< /text >}}
