I would create a table and a method. Every method can call the method and increment in the table the call.
You also can add in a subtable the caller and the simtime. Make it optional, i.e. with checkbox due to performance.
Don't forget to delete the content of the table in reset.
That depends on what you want to do exactly. For "manual" analysis I would recommend using the "Object search" (select "basis/." in the class library and press F3 or right-click > "Object search"), then select "Source code" and tick the box "Ignore inherited content", and search for the name of the method.
Thanks Alex. I was exactly looking for this solution.
I also found another solution by mistake. I renamed a method, but forgot to update the name in each object where the method was used. So when I started the simulation, I got an error.
