Cloud Native CI/CD with GitLab

Key Takeaways

This chapter was dense and covered a lot of ground. Throughout the chapter, we achieved several important milestones:

• We enabled observability for the CI runners so they emit measurable signals about work being done.

• We deployed Prometheus and a Grafana to collect, store, and visualise those signals.

• We connected the runners’ metrics to the Prometheus instance so you can see real-time and historical runner activity.

• We created a custom metric that represents "how many jobs are being processed" so it can be used for decisions.
