Guide to Observability with OpenTelemetry
summary
OpenTelemetry provides a vendor‑agnostic stack: OTLP for transport, SDKs and auto instrumentation for languages, and the OpenTelemetry Collector (receivers → processors → exporters) to route and transform traces, metrics, logs and profiles. The demo uses the OpenTelemetry demo app across multiple languages, shows Elastic ingesting data, correlating failed traces to a single product ID, and an AI-driven workflow that flips a feature‑flag to fix the error. Also covers Kubernetes operator for deploying collectors, continuous profiling, synthetic checks and SLO monitoring.
