Observability Concepts and OpenTelemetry Architecture Overview

Observability turns a black‑box application into a system by gathering logs, metrics, and traces, using alerts to spot anomalies, then linking trace IDs to logs; OpenTelemetry standardizes this with instrumented client agents, a Collector (receivers, processors, exporters), and backend storage, while Java agents, span propagation, exemplars, eBPF, and bundles like SigNoz or OpenObserve let teams choose between a custom OTel stack or a solution.
