OpenTelemetry aiohttp client Integration

This library allows tracing HTTP requests made by the aiohttp client library.

Installation

pip install opentelemetry-instrumentation-aiohttp-client

Example

import asyncio

import aiohttp

from opentelemetry.instrumentation.aiohttp_client import AioHttpClientInstrumentor
from opentelemetry import trace
from opentelemetry.exporter.jaeger.thrift import JaegerExporter
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor


_JAEGER_EXPORTER = JaegerExporter(
   service_name="example-xxx",
   agent_host_name="localhost",
   agent_port=6831,
)

_TRACE_PROVIDER = TracerProvider()
_TRACE_PROVIDER.add_span_processor(BatchSpanProcessor(_JAEGER_EXPORTER))
trace.set_tracer_provider(_TRACE_PROVIDER)

AioHttpClientInstrumentor().instrument()


async def span_emitter():
   async with aiohttp.ClientSession() as session:
      async with session.get("https://example.com") as resp:
            print(resp.status)


asyncio.run(span_emitter())
