This has a lot of difficulties that come along with this doc, and I had troubles too. Read this thread if you want to see what another struggled with, https://redhat-internal.slack.com/archives/C019EPZ233P/p1746623782603609

Where can you find these documentation updated?

https://docs.redhat.com/en/documentation/red_hat_openshift_service_mesh/3.0/html/observability/metrics-and-service-mesh#ossm-config-openshift-monitoring-only_ossm-metrics

Under Prerequisites

• I suggest adding to create an istio CNI intance, as well as an Istio instance

Under Procedure

• #3 PodMonitor.yml, we should remove the namespace that is automatically in the yml
• Step 4: lets change the command to :

   kubectl apply -f podmonitor.yaml -n <your-workload-namespace>

• Put a note under the 2 explaining the PodMonitor.yml stating that specifying the actual mesh ID is for multi-tenants
• Before #5 maybe add a step to have users go to Observe -> Target and search for their workload to make sure the pods are making requests
• After above step: add a command to run:

kubectl port-forward -n bookinfo deployments/productpage-v1 9080:9080 

• After step above: tell the users to run  localhost:9080 in their local browser.
• After completing all of these steps they NOW should be able to go to the Observe->Metrics to run the 

  istio_request_total
  

  query.
