Questions

To assess your learning progress, please answer the following questions:

  1. Why is it important to instrument your application services?
  2. Can you describe to an interested layperson what Prometheus is?
  3. Exporting Prometheus metrics is easy. Can you describe in simple words how you can do this for a Node.js application?
  4. You need to debug a service running on Kubernetes in production. Unfortunately, the logs produced by this service alone don't give enough information to pinpoint the root cause. You decide to troubleshoot the service directly on the respective Kubernetes cluster node. How do you proceed?
