AIOHTTP

The AIOHTTP integration adds support for the AIOHTTP server web framework.

If you use AIOHTTP as your HTTP client and want to instrument outgoing HTTP requests, have a look at the AIOHTTP client documentation.

Install

Install sentry-sdk from PyPI with the aiohttp extra:

pip install --upgrade sentry-sdk[aiohttp]

If you're on Python 3.6, you also need the aiocontextvars package:

pip install --upgrade aiocontextvars

Configure

If you have the aiohttp package in your dependencies, the AIOHTTP integration will be enabled automatically when you initialize the Sentry SDK.

import sentry_sdk

sentry_sdk.init(
    dsn="https://examplePublicKey@o0.ingest.sentry.io/0",
    # Set traces_sample_rate to 1.0 to capture 100%
    # of transactions for tracing.
    traces_sample_rate=1.0,
    # Set profiles_sample_rate to 1.0 to profile 100%
    # of sampled transactions.
    # We recommend adjusting this value in production.
    profiles_sample_rate=1.0,
)

Verify

from aiohttp import web

sentry_sdk.init(...)  # same as above

async def hello(request):
    1 / 0  # raises an error
    return web.Response(text="Hello, world")

app = web.Application()
app.add_routes([web.get('/', hello)])

web.run_app(app)

When you point your browser to http://localhost:8080/ a transaction will be created in the Performance section of sentry.io. Additionally, an error event will be sent to sentry.io and will be connected to the transaction.

It takes a couple of moments for the data to appear in sentry.io.

Behavior

• The Sentry Python SDK will install the AIOHTTP integration for all of your apps.
• All exceptions leading to an Internal Server Error are reported.
• The AIOHTTP integration currently does not attach the request body, see GitHub issue.
• Logging with any logger will create breadcrumbs when the Logging integration is enabled (done by default).

Options

By adding AioHttpIntegration to your sentry_sdk.init() call explicitly, you can set options for AioHttpIntegration to change its behavior:

import sentry_sdk
from sentry_sdk.integrations.aiohttp import AioHttpIntegration

sentry_sdk.init(
    # same as above
    integrations=[
        AioHttpIntegration(
            transaction_style="...",  # type: str
            failed_request_status_codes={...}  # type: collections.abc.Set[int]
        ),
    ],
)

You can pass the following keyword arguments to AioHttpIntegration():

transaction_style

Configure the way Sentry names transactions:

• GET /path/{id} if you set transaction_style="method_and_path_pattern"
• <module_name>.hello if you set transaction_style="handler_name"

The default is "handler_name".

failed_request_status_codes

A set of integers that will determine when an HTTPException should be reported to Sentry. The HTTPException is reported to Sentry if its status code is contained in the failed_request_status_codes set.

Examples of valid failed_request_status_codes:

• {500} will only report HTTPException with status 500 (i.e. HTTPInternalServerError).
• {400, *range(500, 600)} will report HTTPException with status 400 (i.e. HTTPBadRequest) as well as those in the 5xx range.
• set() (the empty set) will not report any HTTPException to Sentry.

The default is {*range(500, 600)}, meaning that any HTTPException with a status in the 5xx range is reported to Sentry.

Regardless of how failed_request_status_codes is set, any exceptions raised by the handler, which are not of type HTTPException (or a subclass) are reported to Sentry. For example, if your request handler raises an unhandled AttributeError, the AttributeError gets reported to Sentry, even if you have set failed_request_status_codes=set().
