Monitoring Lab: A Complete Observability Lab with Go, Spring Boot and Prometheus
Introduction Observability is essential for understanding how applications perform in production. When you can see what your systems are doing, you can make better decisions about performance, resource usage, and reliability. I built a Monitoring Lab to compare how Go and Spring Boot applications perform under similar conditions. Both applications connect to MongoDB and perform the same operations, while Prometheus collects metrics and Grafana visualizes the results. This article focuses on the actual results and what the metrics tell us about the performance differences between these two technologies. ...
