Observability dashboard and incident finder
Collect logs, metrics and traces from a service and find the cause of an incident faster.
The brief
When a service slows down, engineers jump between logs, graphs and traces. Instrument a small service with OpenTelemetry, bring logs, metrics and traces into one dashboard, cause a few incidents on purpose, and measure how long it takes to find each cause with and without the dashboard. Good looks like: trace ids linking logs and traces, alerts with sensible limits, and a timed comparison.
What you will build
- Build a small service with two dependencies
- Instrument with OpenTelemetry
- Collect and show logs, metrics and traces
- Create alerts on error rate and latency
- Inject three incidents
- Time root-cause finding with and without the dashboard
