Hi,
My requirement is to evaluate the performance of new feature of my apps. When a feature is ready, I'd like to trigger a CPU profiling to see whether the methods take long CPU. I used the Tracing CPU profiling, but can't get the method stack and sql in most time. Maybe the YourKit filter the methods which take very tiny time, for example 0.1ms I guess, or some extra configurations needed. I don't want to miss the methods stack even they are not in hot spots. My question is how should I do to see the whole methods stack? Thanks.

Hi,
Please consider changing filters:

Also, you may want to turn adaptive tracing off:

Re: Miss some methods stack
Anton,
Thanks for your quick reply.
I just uncheck "Collapse Filter Calls", and get more call stacks. But I'm afraid I still miss some call stacks since I lost the latest SQL. Do I need to wait some time to stop CPU profiling after my page action? Or is there any tips?

I try the latest beta version, and am evaluating this product to see whether we need buy this tool for our profiling.
