Pragmatic execution tracing

" summary

Tracing captures a full request path with spans and trace IDs so you can pinpoint a missing DB index, a hot CPU hotspot, or a fan‑out that makes latency grow exponentially. Visualization works with Chrome tracing JSON and flamegraphs; backends include Jaeger/Zipkin (Jaeger is a popular CNCF choice). The talk claims OpenTracing vs OpenCensus matters: OpenTracing is a minimal API that leaves propagation to each backend, while OpenCensus provides a propagation format and a metrics API. Getting started often means adding an exporter and middleware—sometimes just two lines of code.
