In a terminal type:

top -bd 30 > topout.txt

which will cause top to run in batch mode and delay 30 seconds each time.
Nothing will show in the terminal.  Press ^C when you want it to stop.  You
could detach (&) the command but then it would be harder to stop, and new
terminal windows are easy to make.  The file will have lots of copies of a
full top list, giving you some history to work from.
