What it shows

  • W3C traceparent standardizes trace-id, parent-id, and trace-flags headers
  • Each hop creates a unique span ID while preserving the original root trace ID
  • OTel Collector aggregates distributed spans into a single searchable DAG

The takeaway

Context propagation binds isolated service spans into a single causality graph without shared memory.
