Monitoring
Repeated observation of a system, practice, or service to detect events and to ensure that the current status is known.
Impact
Monitoring tells you "what" is happening (e.g., CPU is 99%).
Weinto take
Monitoring is necessary but insufficient. We move beyond Monitoring to Observability. Monitoring tells you the system is failing; Observability allows you to ask why by inspecting the internal state via high-cardinality data. Stop collecting dashboards; start collecting traces.
