The Serverless Framework is a popular tool for managing and deploying serverless applications in the cloud. However, monitoring these applications can be challenging due to their unique infrastructure. To address this issue, Datadog has built a Serverless plugin that enables real-time visibility into serverless functions, applications, and cloud infrastructure without requiring any code changes. The plugin supports Lambda functions written in Node.js and Python and includes built-in support for Datadog's AWS X-Ray integration and Lambda Layers. By using the Serverless plugin, users can track custom business metrics, automatically instrument their Lambda functions, and get end-to-end visibility into requests as they travel across their serverless architecture.
