What is Observability? Metrics, Logs & Traces Overview
· via Spacelift
Summary: Metrics tell you something is wrong, traces tell you where, logs tell you why, so design collection around the questions. OpenTelemetry is the sane default now: one instrumentation layer, vendor choice deferred. Cardinality and retention are where observability bills explode, so decide both deliberately.
Who should read it: teams standing up observability from scratch, and anyone consolidating three agents into one pipeline.
