The Three Pillars Fall Short Without Correlation

Modern cloud-native systems generate massive volumes of telemetry: metrics from Prometheus, logs from application pods, and distributed traces from OpenTelemetry instrumentations.

True observability is achieved when every log line contains a distributed trace_id, every metric anomaly links directly to a sample trace waterfall, and every dashboard provides immediate root-cause correlation.
