AWS's serverless technologies, such as Lambda, offer cost-effective scaling and separation of concerns but pose challenges in monitoring due to their transient and abstracted nature. To address this, AWS developed integrated solutions like Amazon CloudWatch and AWS X-Ray, and later introduced the AWS Distribution for OpenTelemetry (ADOT) to facilitate vendor-neutral instrumentation and data export. This text describes how users can instrument Lambda functions with OpenTelemetry and send traces to Grafana Cloud using Grafana Agent as an OTLP endpoint, ensuring scalability and reliability. The process involves creating a Lambda function, adding instrumentation through a Lambda layer, and configuring the Grafana Agent to relay data. The use of OpenTelemetry provides insights into serverless performance, enabling optimization and troubleshooting. Users are encouraged to provide feedback and explore Grafana Cloud’s free tier, which includes various metrics and tracing capabilities.
