recording input/outputs, attributes and parameters of modules

[Jojo Mwe]

i would like to track all inputs/output to modules/functions -if a
module retrieved and used files and run some analysis on them and
produced other files in return, i would like to take not of this. i.e
what i
want is to record all input sand outputs to a module. and also to
record all parameters, attribute vaules used by the same module and
also would like to know how one module calls another whether it
instantiates classes from one module etc

Any help will be highly appreciated..
