How the FourthDown NFL play-by-play API measures its performance with Prometheus, Jaeger, and Grafana Cloud

Pratik Thanki, a software engineer, explores how he uses Grafana Cloud for monitoring his NFL play-by-play API, FourthDown, which allows fans to access a wide range of NFL data. Developed to be language-agnostic and built on ASP.NET Core, the API leverages Prometheus and Jaeger for observability, utilizing logging, tracing, and metrics to monitor and improve performance. Following the launch of a new free plan, Thanki implemented these tools, identifying and resolving performance bottlenecks, leading to significant response time improvements. He expresses enthusiasm for the open-source observability ecosystem and plans to expand monitoring capabilities with Prometheus-based alerting and Loki for logging, inviting others to explore the API through provided documentation and samples.
