autotel-instrumentation

To add tracing and monitoring to Node.js functions, you wrap them using trace() and instrument() functions to automatically create traces and spans. You must also call init() at startup to configure the tracing environment and gain production performance insights.

Function instrumentation in microservices architectures is the process of wrapping functions and handlers to generate detailed traces and spans. It enhances observability by tracking execution flow and performance across distributed serverless services.

Yes, you can instrument API handlers in serverless applications with minimal code changes. By wrapping functions and handlers, the instrumentation automatically manages span creation and traces execution without requiring extensive application refactoring.

Yes, you need to initialize the tracing environment before instrumenting an app. Calling init() at startup configures the necessary tracing context, enabling the trace() and instrument() wrappers to properly generate spans and monitor performance.

Yes, Node.js instrumentation supports span creation for async functions. The tooling allows you to trace your async functions and manage spans within your application, capturing detailed execution metrics and observability data for serverless environments.
