I think pid can be important when watching the log file while the programs are still running. The point of the PID is for the processes that have the same file name and running multiple. such as IE and explorer and many others.
The command path is very helpful for the same reason.

I don't want the log to get out of hand though. Last thing I want is the log file growing to fast on someone.
So far I want to keep the new log file as
