Sample Application to generate OTLP trace data

Refer to quarkusio/quarkus-super-heroes for more information about this sample application.

This example assumes OpenShift is running and is configured to act as an observability hub. Refer to Send Telemetry to OpenShift Cluster.

cd /checkout/of/microshift-observability
oc create ns sample-app

# Deploy the minikube version of application, since it configures NodePort services that we'll want
oc -n sample-app apply -f manifests/sample-instrumented-applications/sample-tracing-app/quarkus-super-heroes.yaml

# Update ui-super-heroes deployment with APP_BASE_URL env variable
oc edit deployment ui-super-heroes -n sample-app

# add the following
    spec:
      containers:
      - env:
        - name: API_BASE_URL
          value: http://<VM_IP>:30489

Create OpenShift ca.crt and serviceaccount token configmaps. This assumes the files ca.crt, edge-token, thanos-receive-url, and ocp-otelcol-url have been scp'd to Microshift VM. For more on that, refer to openshift-observability-hub.

# may need 'oc delete cm/client-ca -n sample-app`, `oc delete cm/edge-token -n sample-app` first
oc create configmap -n sample-app client-ca --from-file ca.crt
oc create configmap -n sample-app edge-token --from-file edge-token

Edit sample-app-otelcol-config.yaml with urls

• copy contents of ~/thanos-receive-url to sample-app-otelcol-config.yaml Line #45
• copy contents of ~/ocp-otelcol-url to sample-app-otelcol-config.yaml Line #35

Finally, exit the MicroShift VM to forward the ui-super-heroes and rest-fights ports to local machine, to access the application and generate traffic with telemetry data.

run from local terminal tabs, not VM

ssh -L 30357:192.168.122.15:30357 redhat@192.168.122.15 -N
ssh -L 30489:192.168.122.15:30489 redhat@192.168.122.15 -N

SSH back into MicroShift VM

oc apply -n sample-app -f ca-cm.yaml
oc apply -n sample-app -f sample-app-otelcol-config.yaml
oc apply -n sample-app -f microshift-otelcol-deployment.yaml
oc get pods -n sample-app # look for running otelcollector pod

Open localhost:30357 from local browser to fight! You should see something like this:

You should now see traces from the sample-app in the OpenShift cluster -n thanos and the Jaeger route. You should be able to view metrics from the quarkus app in -n thanos and thanos-querier route.
