This topic explains how to use the New Relic integration to annotate 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.
LaunchDarkly SDKs that support New Relic will automatically detect whether you have New Relic installed without any additional configuration steps. If LaunchDarkly detects New Relic, LaunchDarkly adds a custom attribute for every feature flag request call made within a New Relic transaction trace.
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.
