LaunchDarkly
Learn how to use Sentry with LaunchDarkly.
Currently in Beta
Feature flag change tracking and feature flag evaluation tracking is currently in open beta.
The LaunchDarkly integration tracks feature flag evaluations produced by the LaunchDarkly SDK. These evaluations are held in memory and sent to Sentry for review and analysis if an error occurs. At the moment, we only support boolean flag evaluations.
Install sentry-sdk from PyPI.
Copied
pip install --upgrade 'sentry-sdk'
Add LaunchDarklyIntegration() to your integrations list:
Copied
import sentry_sdk
from sentry_sdk.integrations.launchdarkly import LaunchDarklyIntegration
sentry_sdk.init(
dsn="https://examplePublicKey@o0.ingest.sentry.io/0",
integrations=[
LaunchDarklyIntegration(),
],
)
The integration is tested by evaluating a feature flag using your LaunchDarkly SDK before capturing an exception.
Copied
import ldclient
import sentry_sdk
client = ldclient.get()
client.variation("hello", Context.create("test-context"), False)
sentry_sdk.capture_exception(Exception("Something went wrong!"))
Visit the Sentry website and confirm that your error event has recorded the feature flag "hello" and its value "false".
Next Steps
- Track feature flag evaluations in other parts of your codebase. If needed, you can set up evaluation tracking for more than one SDK. Read the docs to learn more.
- Set up your change tracking webhook. In order to take full advantage of the feature flag capabilities Sentry offers there is an additional setup step needed. Your feature flag provider needs to notify Sentry when a feature flag definition has changed. A Sentry webhook URL can be registered with your provider. Learn how.
