Sometimes, especially upon login, I have a lot of disk activity. I can use iotop to see what's doing that at a given moment, but I would like to have an integral table over a given time, say the first 5 minutes after I run it.
I'm interested in the percentage breakdown of the disk activity each program was using over the 5 minutes in total.
Is there a tool or a simple script I can run for that cause?

You can use iotop -b (batch mode) inside of a loop based on # of seconds.
That will spit out everything and then redirect it to a file.
I'm trying to find a shell loop example to do that but i don't do shell programming much.
If i started the command by hand, i would run:iotop -botqk > ~/log-iotop.txt or something similar.

I thinkiotop -abtqkmight be what you're looking for -- it will output everything for you with timestamps and when 5 minutes are up, press Ctrl C and it will stop. Then you have everything of the last 5 minutes on your screen that you can scroll through.
