Introducing Datadog's Next-Generation Rust-based Lambda Extension

This article details how to use remote instrumentation to gain deeper insights into AWS Lambda function performance without modifying application code. By leveraging tools like Pyroscope and OpenTelemetry, developers can now collect and analyze metrics like CPU usage, memory allocation, and execution time in real-time, improving troubleshooting and optimization of serverless applications. This approach offers a more flexible and less intrusive way to monitor Lambda functions compared to traditional logging or embedded instrumentation.
