Where to start an OpenTelemetry rollout, how to migrate off OpenTracing without breaking the chain, and why auto-instrumentation always wins by default.
Head-based, consistent-probability, and tail-based sampling — three strategies with real math — plus the four places a Collector can physically live.
Receivers, processors, exporters, pipelines — how the Collector became observability's universal plumbing, and the OTLP protocol underneath it.
OTel doesn't replace your logging framework — it contextualizes it. Why the Logs API is experimental, and how trace IDs get into logs you already have.
Six instrument types, five aggregation strategies, and the cardinality mistakes that make metric backends fall over — OTel's metrics API, explained.
