The current log file basically does shos all of that. Except for one 
thing: If your format loads eg. 1024 hashes at a time and cracks them in 
parallel, those 1024 rules might span several rules. The log file 
illustrates this, best-effort, using wording like "last rule currently 
in use" at times.

To get it more exact than that, we'd need to sacrifice performance. And 
actually I did add such an option to Jumbo years ago. With some (or a 
lot of) performance penalty, you can get a 1:1 mapping in the log file 
using the option "--mkpc=1". You probably also want to set 
LogCrackedPasswords=Y in john.conf.
