Implementing OpenTelemetry in FastAPI Projects Hi Pythonistas, I recently revamped our article on [Implementing OpenTelemetry in FastAPI Projects](https://signoz.io/blog/opentelemetry-fastapi/) in a practical manner, which was originally written in 2024 and needed a fresh coat of paint. The article covers auto-instrumentation, manual spans, visualizing metrics and how observability lets you understand how your web apps behave. I've also included some advanced tips, such as, selective error tracking, and wrapping dependency functions to capture any operations within the \`yield\` scope. Since a lot of the concepts discussed here are independent of the FastAPI framework, any developer working with Python can probably find something of use here. Finally, I hope this write up helps some folks become familiar with OpenTelemetry and observability. Any feedback would be much appreciated, also curious to understand what problems you face with monitoring your web apps, be it FastAPI or any other web framework.…
