Emitting telemetry is the easy half. This module is about the system that receives it, the screens and alerts built on it, what it costs, and how to use it when something is on fire.
| # | Lesson | The question it answers |
|---|---|---|
| 01 | The Telemetry Pipeline | Where does telemetry go after it leaves the process? |
| 02 | Dashboards | What belongs on a screen, and in what order? |
| 03 | Alerting on SLOs | When should a human be woken up? |
| 04 | Sampling and Cost | How do I keep the useful 5% and afford it? |
| 05 | Debugging an Incident | How do I get from a page to a cause? |
When you finish you can draw the pipeline for a real system, build a dashboard someone else can read under pressure, write a burn-rate alert, and budget the telemetry bill.
