--- package: "@opentelemetry/instrumentation-http" version: "^0.55.0" tier: core decision: approved date: 2026-05-14 deciders: [Danijel Martinek] adr: adr-017 filter-results: license: Apache-2.0 types: native maintenance: active boundary-fit: pass shadow-check: pass eu-residency: n/a cve-scan: clean named-consumer: pass verification-commands: - npm view @opentelemetry/instrumentation-http license - npm view @opentelemetry/instrumentation-http version - pnpm audit --audit-level=moderate accepted-cves: [] --- ## Filter: license `npm view @opentelemetry/instrumentation-http license` returns `Apache-2.0`. Apache-2.0 is on the allowlist. ## Filter: types `@opentelemetry/instrumentation-http` is authored in TypeScript and ships its own `.d.ts` declaration files. No separate `@types/` package is needed. ## Filter: maintenance Actively maintained by the OpenTelemetry community as the first-party HTTP instrumentation plugin. The 0.55.x line is current and tracks the OTel SDK release cycle. ## Filter: boundary-fit ADR-017 §11 explicitly enables HTTP auto-instrumentation in `initOtelServerNode`. The plugin is configured with query-string stripping on `http.url.path` and a path ignore list (`/_health`, `/_otel-export`) to prevent noise and PII leakage. Restricted to `core-shared/instrumentation/otel/` init paths. ## Filter: shadow-check `@opentelemetry/instrumentation-http` is the standard OTel HTTP auto-instrumentation. No competing HTTP span emitter is present in the workspace. ## Filter: eu-residency `@opentelemetry/instrumentation-http` is a pure instrumentation plugin with no independent data transmission. Spans it emits are routed through the configured OTel exporter (Sentry via `@sentry/opentelemetry`). EU residency is governed by the exporter configuration. ## Filter: cve-scan `pnpm audit --audit-level=moderate` reports no advisories against `@opentelemetry/instrumentation-http` at the time of this trace. ## Filter: named-consumer `packages/core-shared/src/instrumentation/otel/init-otel-server-node.ts` registers `HttpInstrumentation` with query-string redaction and path ignore rules (ADR-017 §11). This eliminates manual span creation for every incoming HTTP request and outgoing HTTP call. ## Prompt: replaces Manual `tracer.startSpan()` / `tracer.endSpan()` wrapping around every `http.IncomingMessage` handler and `http.request()` call site. The auto-instrumentation patches Node.js core `http` and `https` modules to emit spans automatically. ## Prompt: migration-cost-out Low. `HttpInstrumentation` is registered in one init file. Removing it means disabling the plugin registration and optionally adding manual spans at HTTP boundaries — localized to the SDK init and any call sites that relied on automatic context propagation. ## Prompt: alternatives-considered 1. **Manual HTTP spans** — No plugin needed, but requires wrapping every `http.request` and route handler explicitly. Rejected: high boilerplate, easy to miss call sites, loses automatic context propagation headers. 2. **`dd-trace` HTTP plugin** — Datadog-specific. Rejected in ADR-017: vendor lock-in; OTel plugin achieves the same coverage with vendor-neutral output. See ADR-017 for the full decision rationale.
