OTLP on the Wire teaches engineers to read the OpenTelemetry Protocol byte by byte.

Most OpenTelemetry material stops at SDK instrumentation and Collector configuration. This book goes one layer lower: it takes real OTLP trace, metric, and log payloads and decodes them from raw bytes through Protobuf records, OTLP schema, gRPC framing, HTTP transport, packet captures, failure modes, and telemetry cost.

The book is built around reproducible specimens: deterministic fixtures, deliberately broken payloads, packet captures, parsers, tests, and benchmark scripts. The method is simple: start with bytes, identify which layer owns their meaning, prove the interpretation, then connect the structure to reliability and FinOps.

This is not an OpenTelemetry introduction. It is for observability engineers, platform engineers, SREs, telemetry engineers, protocol-curious backend engineers, and anyone building or operating OpenTelemetry infrastructure.
