Logging All Function Calls in a Project

Hello there, I want to log all function calls in my project. I looked into using interceptors and AspectJ, but I cannot use them in this project. Interceptors are not working (possibly due to misconfiguration), and I’m unable to configure AspectJ. I would greatly appreciate any help in this area. I’m aware that this functionality may introduce a heavy load, but it’s only for experimental reporting purposes.
