The article discusses the limitations of CI/CD pipelines, which primarily analyze macro-level metrics, in identifying performance issues like OutOfMemoryError. It emphasizes the importance of micrometrics—such as garbage collection throughput, thread states, and memory waste—in monitoring applications to preemptively address performance problems and improve software quality in production.
Performance tests in enterprises often report macro metrics like CPU utilization and response times. However, these metrics can miss acute performance degradations and hinder troubleshooting. Incorporating micro metrics, such as Garbage Collection pause times and thread states, provides deeper insights and facilitates better performance management and debugging efforts for development teams.
