OpenShift Lab 10: View Pod, Workload, and Namespace Performance Metrics Using the OpenShift Web Console

Updated lab flow

1. Start OpenShift Local.
2. Log in to the web console.
3. Create project lab10-performance-demo.
4. Deploy a lightweight web app or resource-pressure Job.
5. View pods and workload details in Topology.
6. Open Observe → Dashboards.
7. Select dashboard:Kubernetes / Compute Resources / Namespace (Workloads)
8. View CPU, memory, network receive/transmit, pod count, and workload metrics.
9. Use Observe → Metrics to run simple PromQL queries.
10. Validate from CLI using:

oc get pods
oc get jobs
oc logs job/rpjob
oc adm top pods
Code language: JavaScript (javascript)

11. Explain why metrics may take 30–60 seconds to appear.
12. Clean up the project.

One important update: Red Hat’s monitoring docs note that from OpenShift 4.19 onward, the web console perspectives changed and the Developer perspective is no longer enabled by default in the same way, so our lab should avoid depending too heavily on old Developer Sandbox screenshots. We can still mention Developer/Administrator views, but we should write the steps flexibly for the current console. (Red Hat Documentation)
