OpenTelemetry HTTPX Instrumentation

Project description

pypi

This library allows tracing HTTP requests made by the httpx library.

Installation

pip install opentelemetry-instrumentation-httpx

Usage

Instrumenting all clients

When using the instrumentor, all clients will automatically trace requests.

import httpx
from opentelemetry.instrumentation.httpx import HTTPXClientInstrumentor

url = "https://httpbin.org/get"
HTTPXClientInstrumentor().instrument()

with httpx.Client() as client:
     response = client.get(url)

async with httpx.AsyncClient() as client:
     response = await client.get(url)

Instrumenting single clients

If you only want to instrument requests for specific client instances, you can use the instrument_client method.

import httpx
from opentelemetry.instrumentation.httpx import HTTPXClientInstrumentor

url = "https://httpbin.org/get"

with httpx.Client(transport=telemetry_transport) as client:
    HTTPXClientInstrumentor.instrument_client(client)
    response = client.get(url)

async with httpx.AsyncClient(transport=telemetry_transport) as client:
    HTTPXClientInstrumentor.instrument_client(client)
    response = await client.get(url)

Uninstrument

If you need to uninstrument clients, there are two options available.

import httpx
from opentelemetry.instrumentation.httpx import HTTPXClientInstrumentor

HTTPXClientInstrumentor().instrument()
client = httpx.Client()

# Uninstrument a specific client
HTTPXClientInstrumentor.uninstrument_client(client)

# Uninstrument all clients
HTTPXClientInstrumentor().uninstrument()

Using transports directly

If you don’t want to use the instrumentor class, you can use the transport classes directly.

import httpx
from opentelemetry.instrumentation.httpx import (
    AsyncOpenTelemetryTransport,
    SyncOpenTelemetryTransport,
)

url = "https://httpbin.org/get"
transport = httpx.HTTPTransport()
telemetry_transport = SyncOpenTelemetryTransport(transport)

with httpx.Client(transport=telemetry_transport) as client:
    response = client.get(url)

transport = httpx.AsyncHTTPTransport()
telemetry_transport = AsyncOpenTelemetryTransport(transport)

async with httpx.AsyncClient(transport=telemetry_transport) as client:
    response = await client.get(url)

Request and response hooks

The instrumentation supports specifying request and response hooks. These are functions that get called back by the instrumentation right after a span is created for a request and right before the span is finished while processing a response.

The hooks can be configured as follows:

from opentelemetry.instrumentation.httpx import HTTPXClientInstrumentor

def request_hook(span, request):
    # method, url, headers, stream, extensions = request
    pass

def response_hook(span, request, response):
    # method, url, headers, stream, extensions = request
    # status_code, headers, stream, extensions = response
    pass

HTTPXClientInstrumentor().instrument(request_hook=request_hook, response_hook=response_hook)

Or if you are using the transport classes directly:

from opentelemetry.instrumentation.httpx import SyncOpenTelemetryTransport

def request_hook(span, request):
    # method, url, headers, stream, extensions = request
    pass

def response_hook(span, request, response):
    # method, url, headers, stream, extensions = request
    # status_code, headers, stream, extensions = response
    pass

transport = httpx.HTTPTransport()
telemetry_transport = SyncOpenTelemetryTransport(
    transport,
    request_hook=request_hook,
    response_hook=response_hook
)
