How to log the Ram and CPU usage for Linux Processes

Question

How would I track the CPU and Ram usage for a process that may run, stop, and then re-run with a different PID?

I am looking to track this information for all processes on a Linux server but the problem is when the process stops and restarts, it will have a different PID and I am not sure how to identify it as the same process.

What you're looking for here is called "process accounting".
