Observability vs Monitoring: Key Differences Explained
· via Spacelift
Summary: Monitoring watches for known failure modes, observability lets you interrogate unknown ones, and the distinction decides what you build and what you buy. The two complement each other: dashboards and alerts on top, rich telemetry underneath for the incidents that fit no dashboard. Get monitoring right first, then invest in the high-cardinality telemetry that makes systems explorable.
Who should read it: anyone writing an observability strategy, and engineers who suspect their dashboards only cover the failures already seen.
