LaunchDarkly

Learn about the LaunchDarkly integration and how to add it to your integrations list.

The LaunchDarkly integration tracks feature flag evaluations produced by the LaunchDarkly SDK. These evaluations are held in memory and, in the event an error occurs, sent to Sentry for review and analysis.

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".
