Monitoring vs Observability

Summary

Monitoring tracks known metrics against known thresholds ('is CPU above 80%?'); observability is the broader ability to ask new, unanticipated questions about system state from its outputs — you need both.

• 1Give one example of a monitored metric and one example of an observability-driven investigation.
• 2Learn why observability matters more as systems get more distributed and unpredictable.
• 3Understand monitoring answers known questions; observability helps you find the right question.
