Logging and Auditing functions executed by Emacs Lisp interpreter

[Narendra Joshi <narendraj9@gmail.com>]

Hi,

I use a package- `elisp-demos`, which adds examples of Emacs Lisp 
functions to `help` buffers. I was curious to know whether it 
executed the examples on my machine to show their output or not. I 
figured out that the output is also hard-coded in the package 
files. This led me to start looking for something that would allow 
me to see what the Emacs Lisp interpreter is evaluating, e.g. the 
functions that it had to call during evaluation. Something similar 
to `view-lossage` but that includes non-interactive functions 
(e.g. network calls made from installed packages, processes 
spawned, or functions being called by timers regularly). Is there 
such a feature in Emacs?
