Chapter 9. Integrating Red Hat OpenShift distributed tracing platform with Kiali Operator provided by Red Hat

You can integrate Red Hat OpenShift distributed tracing platform with Kiali Operator provided by Red Hat, which enables the following features:

  • Display trace overlays and details on the graph.
  • Display scatterplot charts and in-depth trace/span information on detail pages.
  • Integrated span information in logs and metric charts.
  • Offer links to the external tracing UI.

9.1. Configuring Red Hat OpenShift distributed tracing platform with Kiali Operator provided by Red Hat

After Kiali Operator provided by Red Hat is integrated with Red Hat OpenShift distributed tracing platform, you can view distributed traces in the Kiali console. Viewing these traces can provide insight into the communication between services within the service mesh, helping you understand how requests are flowing through your system and where potential issues might be.

Prerequisites

  • You installed Red Hat OpenShift Service Mesh.
  • You configured distributed tracing platform with Red Hat OpenShift Service Mesh.

Procedure

  1. Update the Kiali resource spec configuration for tracing:

    Example Kiali resource spec configuration for tracing

    spec:
  external_services:
    tracing:
      enabled: true 1
      provider: tempo
      use_grpc: false
      in_cluster_url: http://tempo-sample-query-frontend.tempo:3200
      url: https://tempo-sample-query-frontend-tempo.apps-crc.testing 2

    1
    Enable tracing.
    2
    The OpenShift route for Jaeger UI must be created in the Tempo namespace. You can either manually create it for the tempo-sample-query-frontend service, or update the Tempo custom resource with .spec.template.queryFrontend.jaegerQuery.ingress.type: route.
  2. Save the updated spec in kiali_cr.yaml.

  3. Run the following command to apply the configuration: 

    $ oc patch -n istio-system kiali kiali --type merge -p "$(cat kiali_cr.yaml)"

    Example output:

     kiali.kiali.io/kiali patched

Verification

  1. Run the following command to get the Kiali route: 

    $ oc get route kiali ns istio-system
  2. Navigate to the Kiali UI.
  3. Navigate to Workload Traces tab to see traces in the Kiali UI.
