Identifying memory leaks in Spring involves using tools like VisualVM, JConsole, and Heap Dump analysis.

• Use tools like VisualVM or JConsole to monitor memory usage and identify potential leaks

• Analyze heap dumps to identify objects that are not being garbage collected

• Look for objects that have strong references but are no longer needed

• Check for potential memory leaks in Spring beans or application context

I monitor the application stack through automated monitoring tools and manual checks.

• Utilize monitoring tools like Nagios, Zabbix, or Prometheus to track performance metrics

• Set up alerts for key indicators such as CPU usage, memory usage, and response times

• Regularly review logs and error messages to identify issues and trends

• Perform manual checks on application components to ensure proper functioning

• Implement automated tests to validate the integrity of the application stack
