Is there any reason you don't want to use a simple script?  E.g.

touch topper
date >> topper
echo " " >> topper
while (whatever-condition-suits-your-need)
do
  top n 1 >> topper
  echo "=======================================================" >> topper
  sleep 30   # That's a snapshot every 30 seconds; change as needed
done

Note that "top" is relatively cpu-intensive; you might use "ps | grep",
maybe with "uptime" or something similar; yes, "top" gives more info, but
it rather sounds like overkill for your needs.
