Instrumentation of gRPC in OpenTelemetry: Adding Request Size Metrics via Byte‑Buddy

The new OpenTelemetry Java instrumentation adds client and server request‑size metrics to gRPC by injecting a tracing interceptor via Byte‑Buddy bytecode enhancement, extracting payload sizes from protobuf messages, recording them with custom attributes and histograms, and applying analogous handler‑based logic for Go.

Limitations of Spring AOP and Java Agent Solutions for the Diagnose Framework

Spring AOP cannot advise non‑bean, static, or internally‑called methods, limiting its use for the Diagnose framework, so the article proposes a Java Agent that transforms bytecode at startup, bypasses proxy constraints, and reliably intercepts private, static, and self‑invoked methods across separate class loaders.
