Datadog has released real-time distributed tracing support for .NET Lambda functions, providing comprehensive visibility into serverless applications and enabling developers to identify and resolve issues such as exception errors and cold starts. With this feature, .NET developers can trace all requests across their entire infrastructure with minimal overhead, spotting pain points anywhere in the system without code or configuration changes. Datadog's APM provides an end-to-end view of requests as they traverse any component of the infrastructure, including Lambda functions, containers, and on-prem hosts, enabling developers to easily identify bottlenecks and determine whether .NET Lambda function errors are behind issues. The feature also detects cold starts automatically, allowing developers to isolate and view their durations, and provides code-level insights into .NET Lambda functions, such as divide-by-zero or null reference errors. Datadog's full support for .NET Lambda functions enables real-time visibility into serverless applications, correlating with other telemetry available through the Lambda Library and Extension to gain further insight into any issue.
