Here is a script you can run from a cron job at whatever interval you want.

Don't forget to delete the file once in a while. It will get BiG!!

I suggest running it every 5 minutes for hour 9 and every 1 minute for 10...

Just change the "-n25" bit to have more or less output.

#!/bin/bash

# create a log of top output where new data is
# appended to the beginning of the log not the end

cd /home/sites/home/web/
mv top.log top.log.old
top -b -n1 | head -n25 > top.log
cat top.log.old >> top.log
rm top.log.old
