Switch over to istio-system project
$ oc project istio-system
Install Zipkin for tracing and expose the service as route so that you can access Zipkin UI.
$ oc apply -f install/kubernetes/addons/zipkin.yaml
$ oc expose svc zipkin
Install Prometheus for metrics and expose the service as route to access Prometheus.
$ oc apply -f install/kubernetes/addons/prometheus.yaml
$ oc expose svc prometheus
Prometheus uses Grafana for visualization of metrics. Expose the service to get the UI.
$ oc apply -f install/kubernetes/addons/grafana.yaml
$ oc expose svc grafana
Service graph allows you to visualize in microservices call tree. Let's install servicegraph and expose the service to get the UI.
$ oc apply -f install/kubernetes/addons/servicegraph.yaml
$ oc expose svc servicegraph
If you list the routes in the istio-system project you will get all the URLs that you can access.
$ oc get route
NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD
grafana grafana-istio-system.127.0.0.1.nip.io grafana http None

Open up the following URLs in the browser. As of now that data will all be empty as we don't have any application running yet.
To access service graph as a graph use /dotviz suffix
http://servicegraph-istio-system.127.0.0.1.nip.io/dotviz
To access Istio dashboard on Grafana use:
http://grafana-istio-system.127.0.0.1.nip.io/dashboard/db/istio-dashboard
For tracing using zipkin: http://zipkin-istio-system.127.0.0.1.nip.io/zipkin/
At this point we are ready to deploy an application and test.
