Revise and Test the Concepts
We explored quite a few
Prometheus metrics, expressions, and alerts. We saw how to connect
Prometheus alerts with
Alertmanager and, from there, to forward them from one application to another.
What we did so far is only the tip of the iceberg. It would take too much time (and space) to explore all the metrics and expressions we might use. Nevertheless, I believe that now you know some of the more useful ones and that you’ll be able to extend them with those specific to you.
For now, I’ll leave you to decide whether to move straight into the next chapter, to destroy the entire cluster, or only to remove the resources we installed. If you choose the latter, please use the commands that follow.
helm delete prometheus \
helm delete go-demo-5 \
kubectl delete ns go-demo-5 metrics
