OpenTelemetry aiohttp client instrumentation
Decision gist · record as of 2026-08-14
Yes, if you are already using OpenTelemetry and aiohttp in an async application. The low install friction, active maintenance, and zero known vulnerabilities make it a straightforward addition. Beta status is not a blocker—it reflects the OpenTelemetry contrib project's versioning, not instability. Skip it if you are not instrumenting with OpenTelemetry or do not use aiohttp.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; aiohttp client library must be installed separately to instrument.
- Low friction install with a small, stable dependency chain.
- Active maintenance as of 2026-08-13 with recent releases.

What it is and what it does
This package integrates OpenTelemetry tracing into aiohttp's HTTP client, automatically capturing spans for each outbound HTTP request. It wraps aiohttp client calls to emit trace data—including request method, URL, status code, and timing—that flows into your configured OpenTelemetry exporters (e.g., Jaeger, Datadog, or local collectors). It depends on opentelemetry-api, opentelemetry-instrumentation, opentelemetry-semantic-conventions, opentelemetry-util-http, and wrapt to hook into aiohttp's request lifecycle.
The package is designed for teams already running OpenTelemetry infrastructure who need visibility into async HTTP traffic. It follows the OpenTelemetry Python instrumentation pattern: call the instrumentor once at startup, and all subsequent aiohttp client requests will emit traces automatically. It's maintained as part of the opentelemetry-python-contrib repository and is in Beta status, meaning the API may evolve but the core functionality is stable.
Use it for
- Trace outbound HTTP calls in async microservices to correlate requests across service boundaries.
- Debug slow or failing aiohttp requests by examining captured spans and timing data.
- Monitor HTTP client behavior in production by exporting traces to a centralized observability backend.
- Correlate aiohttp client requests with server-side traces using OpenTelemetry context propagation.
- Audit HTTP traffic patterns and response times from async applications without code changes beyond one-time instrumentation.
