37 / 38

ProductAnswers
MonitoringIs something wrong right now?
LoggingWhat exactly happened?
TraceWhere did the time go in this request?
ProfilerWhere does the app spend its own CPU/memory?
The common mistake this slide exists to prevent: grepping logs to reconstruct request timing when Trace already shows the span waterfall directly — real, avoidable wasted investigation time.
