Learning objectives

What you should understand

  1. Separate hot-path event capture from cold-path aggregation
  2. Use bounded, nonblocking telemetry channels
  3. Measure observability overhead and loss

Lab

Hands-on exercise

Add metrics and traces, then prove their hot-path cost.

Deliverable

Evidence of completion

An observability budget with overload and data-loss behavior.
