Feedback exercise 5

[Nadine2016]

1. I think what could really help here is a description of the included telemetry services that come with istio and the reason why I would want to use any of these.
2. Not sure if I just did not set it up correctly, but when I was trying to execute kubectl apply -f install/kubernetes/addons/grafana.yaml, I was still in the v2 folder from the previous exercise, so this command did not work for me.
3. I could not find where the Ingress variable is set that contains the Ingress IP. so the command where you create the workload did not work. Any reason why you do not use the IBM-provided sub domain?
4. request-count did not exist for me, instead I found istio_double_request_count
5. I had several commands failing:

ibm$ kubectl port-forward -n istio-system \$(kubectl get pod -n istio-system -l app=jaeger -o \jsonpath='{.items[0].metata.name}') 16686:16686 &
-bash: syntax error near unexpected token `('

- ibm$ kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app=grafana \  -o jsonpath='{.items[0].metadata.name}') 3000:3000
error: name cannot be provided when a selector is specified
error: TYPE/NAME and list of ports are required for port-forward

6. Browsing to http://localhost:8088/dotviz did not work, although port forwarding was successful
7. Mixer log stream: I did not understand what I am seeing here or what I am looking for after I executed this command.

@szihai Can you please help to fix few issues in https://github.com/IBM/istio101/tree/master/workshop/exercise-5 ?

The ones I don't know how to fix are below

1. Grafana throws an error below when I run kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app=grafana \ -o jsonpath='{.items[0].metadata.name}') 3000:3000

error: name cannot be provided when a selector is specified error: TYPE/NAME and list of ports are required for port-forward See 'kubectl port-forward -h' for help and examples.

2. Prometheus dashboard doesn't show istio_request_count

3. Service graph dashboard doesn't come up

4. Mixed log stream do nothing.

The reason why they work earlier is that I was testing with your repo. Once I tried them with Lin's repo, they start failing because it has services with different hierarchy.

I don't have any problems with the commands. Did you take out the "\" in the commands? it was meant to split lines.

[nilesh32]

This one works now. @szihai confirmed it as well. We can close the issue

Closing per @nilesh32's request
