If you want to trace all methods in a jar then I recommend you find a different tool. Byteman is normally used to transform single methods or small groups of methods. Bulk method transformations are better done using a general purpose Aspect Oriented Programming tool (for example you might look at AspectJ).
It is possible to use Byteman do what you want. You would have to write a standalone program to read each class in your jar, use reflection to identify the methods of the class and then generate a Byteman rule to track entry and exit times for each method, dumping the method name and elapsed time at exit. If you are not familiar with Java then I don't think you will find it easy to write this program.
