If you have control over starting the program then "time" will probaby suffice.

time - time a simple command or give resource usage

DESCRIPTION
       The  time  command  runs  the specified program command with the given
       arguments.  When command finishes, time writes a message  to  standard
       output giving timing statistics about this program run.  These statis-
       tics consist of (i) the elapsed real time between invocation and  ter-
       mination,  (ii)  the  user  CPU  time  (the  sum  of the tms_utime and
       tms_cutime values in a struct tms as returned by times(2)), and  (iii)
       the system CPU time (the sum of the tms_stime and tms_cstime values in
       a struct tms as returned by times(2)).
