Under the hood of New Relic’s Lambda Extension

New Relic's integration with AWS Lambda Extensions provides engineers with the ability to directly access AWS Lambda log streams, bypassing Amazon CloudWatch, to manage cloud expenses while maintaining observability. This integration allows users to collect, enhance, and transport telemetry data directly to New Relic One's Telemetry Data Platform, offering deeper insights into AWS Lambda functions. The New Relic Lambda extension functions as a lightweight tool that operates within the Lambda execution environment to buffer and periodically send telemetry data, overcoming previous challenges associated with using CloudWatch. By utilizing AWS Secrets Manager for license key management, the extension ensures efficient telemetry data handling and minimizes AWS costs. Additionally, metadata decoration enriches the telemetry data with function configuration details, enabling advanced data querying and analysis in New Relic One. Overall, the extension allows users to observe and understand the performance of their serverless applications while optimizing their cloud spend.
