What tools do I need to trace performance bottlenecks end-to-end?

None fancy. UUIDs, structured logs, Elasticsearch or Datadog for queries. OpenTelemetry if you scale.

How do trace IDs fix distributed tracing issues?

They chain timings across services — sum durations, spot the 450ms culprits averages hide.

Absolutely. One team shaved 12s loads to instant, no subscriptions needed.

Your app's fine—until it's not. Distributed bottlenecks lurk between services, mocking your dashboards. Time to trace 'em properly.
