How can I troubleshoot performance issues using VisualVM?
An example of an AI chatbot conversation about troubleshooting performance issues with VisualVM.
How can I troubleshoot performance issues using VisualVM?
To troubleshoot performance issues with VisualVM, start by monitoring CPU and memory usage. What specific issues are you facing?
I'm noticing high CPU usage, but I'm not sure which process is causing it.
You can use the 'Sampler' feature in VisualVM to identify which threads are consuming the most CPU. Have you tried that?
No, I haven't. How do I access the Sampler?
In VisualVM, select your application from the left panel, then click on the 'Sampler' tab. You can start sampling CPU usage from there.
Thanks! That sounds helpful. What should I do if I find a specific thread causing the issue?
If you identify a problematic thread, you can analyze its stack trace to understand what it's doing. You might need to optimize the code or check for deadlocks.
