OpenTelemetry Collector component configuration: config keys, defaults, validation rules, signal support, stability, and gotchas. Progressive disclosure via components/<type>.md; currently covers log_dedup and interval processors.

OpenTelemetry declarative YAML configuration for SDK setup (otelconf, OTEL_CONFIG_FILE, file_format). Points at upstream schema, env-var substitution, and configuration precedence.

OpenTelemetry Transformation Language (OTTL) expert for writing and debugging telemetry transformations in the Collector (transform, filter, routing, tail_sampling).

OpenTelemetry SDK and package version lookup across languages.

OpenTelemetry semantic convention lookup and naming guidance for attributes, groups, and span naming.

Migrate OpenTelemetry Span Events (AddEvent, RecordException) to the Logs API following the OTEP 4430 deprecation plan.

Construct telemetrygen commands for generating synthetic OpenTelemetry traces, metrics, and logs via OTLP; load-test collectors and validate pipelines.

OpenTelemetry Weaver registry authoring, codegen, and CI enforcement (registry check/generate/diff).

OpenTelemetry in Go: declarative SDK setup with otelconf, API surface, contrib instrumentation libraries (otelhttp, otelgrpc), performance tuning, breaking-change audits.

OpenTelemetry in Java: Javaagent zero-code instrumentation, Spring Boot Starter, manual autoconfigure SDK, declarative YAML configuration, BOM dependency management.

OpenTelemetry in Node.js / JavaScript / TypeScript: NodeSDK, declarative YAML configuration, auto-instrumentations, ESM vs CJS import patterns.

OpenTelemetry in Python: declarative SDK setup (experimental file config), API surface and logging bridge, zero-code instrumentation (opentelemetry-distro / opentelemetry-instrument) and contrib catalog, performance tuning, breaking-change audits.

OpenTelemetry in .NET: DI/builder SDK setup (OpenTelemetry.Extensions.Hosting), native BCL instrumentation (ActivitySource, Meter, ILogger), zero-code CLR-profiler agent and contrib instrumentation catalog, performance tuning, breaking-change audits. Note: .NET has no declarative YAML config yet.

OpenTelemetry in the browser (Real User Monitoring / RUM): web tracing SDK (sdk-trace-web, context-zone) and experimental browser-sdk, event- and span-based browser instrumentations (web vitals, navigation, errors, fetch/XHR), sessions, frontend-to-backend trace propagation, bundle size / cost / PII trade-offs.
