Continuous Integration/Continuous Deployment (CI/CD) is vital for software quality, yet issues like OutOfMemoryError can arise despite testing. To mitigate these, micrometrics such as Garbage Collection Throughput, Thread Count, and Wasted Memory should be monitored as indicators of performance problems. Proper integration of these metrics enhances reliability in production.
Performance testing in enterprises includes gathering macro metrics like CPU utilization and response times. However, these metrics have limitations, such as failing to catch acute performance issues and complicating troubleshooting. Complementing macro metrics with micro metrics—focusing on memory, thread, and network activities—enhances visibility and aids in addressing performance problems effectively.
