Just a math guy lost in the IT world

welcome to this hands-on lab on API instrumentation using Prometheus and FastAPI! In the world of modern software development, real-time API monitoring is essential for understanding usage patterns, debugging issues, and ensuring optimal performance. In this lab, we’ll demonstrate how to enhance a FastAPI-based application with Prometheus metrics to monitor its behavior effectively. We’ve already set up the lab environment for you, complete with Grafana, Prometheus, and a PostgreSQL database. While FastAPI’s integration with databases is outside the scope of this lab, our focus will be entirely on instrumentation and monitoring. For those interested in exploring the database integration or testing , you can review the code in our repository: FastAPI Monitoring Repository . What You’ll Learn In this lab, we’ll walk you through: Setting up Prometheus metrics in a FastAPI application.
