Observability: Prometheus + Grafana + Jaeger for 5GC

The Three Pillars of Observability

Observability in cloud-native telecom rests on three pillars: metrics, logs, and traces. Metrics are numerical measurements collected at regular intervals that capture system behavior over time, such as CPU utilization, request rates, and error counts. Logs are timestamped text records of discrete events, providing detailed context about what happened and when. Distributed traces follow individual requests as they traverse multiple NFs across the service mesh, revealing latency bottlenecks and failure points. Together these three pillars provide operators with the visibility needed to detect…
