Get Started    

New Relic

The New Relic integration annotates New Relic transactions with feature flag information. You can use this data to correlate feature flag variations with changes in application performance or error rates.

SDK Support

Currently, New Relic integration is only available for Java and Ruby. Support for other platforms is coming soon.

You don't need to do anything to set up New Relic integration. Our SDK will automatically detect whether you have New Relic installed without any additional configuration steps. Once New Relic is detected, LaunchDarkly will add a custom attribute for every feature flag request call made within a New Relic transaction trace.

In this transaction, a feature flag with key `map.save.header` was requested, and the variation returned was `true`.

In this transaction, a feature flag with key map.save.header was requested, and the variation returned was true.

You can see custom attributes for particular transactions on your New Relic dashboard, or use NRQL to explore how feature flags impact performance across many transactions.
