OTEL in Practice
Add OTel SDK, set exporters, propagate context across async boundaries.
Sampling
Start with parent-based traceidratio at 0.1 → increase for incidents.
Dashboards
Hook to Grafana or Datadog; chart latency, error rate, and saturation.
Traces, metrics, and logs wired cleanly with OTel—sampling, baggage, and dashboards.
