Serverless
Learn about using Sentry's Python SDK for a serverless environment.
The Serverless integration adds support for the Serverless Framework.
It is recommended to use an integration for your particular serverless environment if available, as those are easier to use and capture more useful information:
If you use a serverless provider not directly supported by the SDK, you can use this generic integration.
Install sentry-sdk
from PyPI:
pip install --upgrade 'sentry-sdk'
Apply the serverless_function
decorator to each function that might throw errors:
import sentry_sdk
from sentry_sdk.integrations.serverless import serverless_function
sentry_sdk.init(
dsn="https://examplePublicKey@o0.ingest.sentry.io/0",
enable_tracing=True,
)
@serverless_function
def my_function(...): ...
Use the generic integration by calling the serverless_function
decorator. Decorators wrap a function and modify its behavior. Then, deploy and test the function.
Wrap a functions with the serverless_function
that triggers an error:
@serverless_function
def my_function(...):
1/0 # raises an error
Now deploy your function. When you now run your function an error event will be sent to sentry.io.
Each call of a decorated function will block and wait for current events to be sent before returning. When there are no events to be sent, no delay is added. However, if there are errors, it will delay the return of your serverless function until the events are sent. This is necessary as serverless environments typically reserve the right to kill the runtime/VM when they consider it is unused.
You can add more context as described here.
Request data is attached to all events: HTTP method, URL, headers, form data, JSON payloads. Sentry excludes raw bodies and multipart file uploads. Sentry also excludes personally identifiable information (such as user ids, usernames, cookies, authorization headers, IP addresses) unless you set
send_default_pii
toTrue
.Each request has a separate scope. Changes to the scope within a view, for example setting a tag, will only apply to events sent as part of the request being handled.
The maximum amount of time to block overall is set by the shutdown_timeout
client option.
You can disable this aspect by decorating with @serverless_function(flush=False)
instead.
