How can I monitor my harddrive throughput?

I frequently find applications taking up all of my harddrive's bandwidth, and I'd like to be able to monitor my HDD's throughput, and preferably what applications are using how much of it's bandwidth. How can I do this?

Well you can write a script to do what you want easily enough, as the per process I/O statistics are maintained in /proc. For example, to report on your web server's I/O:

Code:

ps -A | grep -i http | awk '{print "cat /proc/" $1 "/io"}' | bash

And of course iostat will show you global info for the drives.
