You need to look at system accounting. The command 'sa' reports on
accounting information and the command 'accton' turns on per process
accounting.  It's not usually turned on by default (on busy systems the
accounting files can get large) and it's not retrospective. (So if it's
not turned on, any per-process logs are lost once the process
terminates.)
