Description
Hello,
First of all, thanks to all the developers who continue to keep this project alive. I would like to ask if there is a way to extract information from a JFR file via the command line. My JFR file is generated automatically during the execution of software I wrote. Through the GUI on the Sampler Tab, I can see all the processes that have been executed, along with their respective functions, execution times, and CPU usage. Is it possible to get the same information in a text file extracted via the command line?
I need to extract this information dynamically during the mass execution of my software to check if execution times and resource usage remain consistent. Thank you very much for your support.

Research direction
Start with the JFR information shown in the GUI's Sampler Tab and determine whether it has an existing command-line entry point. Done would mean extracting the requested process, function, execution-time, and CPU-usage information into a text file during automated runs.
