System Monitor gives me a graphical display of Network data flow.

Is there something similar for the data flow on the local file-system itself?

iostat -m shows the I/O per device that has been caused since system startup.

You can combine it with watch 'iostat -m'

Thanks... Your iostat and NightwishFan's iotop work well together in a split Terminal window (the broad picture, and the detail). –  Peter.O Oct 30 '10 at 1:26

There is a System Monitor gnome-panel applet that shows a tiny graph of IO. Also you can use the program iotop, which is like top/htop in the console though for I/O.

iotop works well enough (for me), but my kernal isn't compiled suitably to allow it to output some of its features... CONFIG_TASK_DELAY_ACCT not enabled in kernel, cannot determine SWAPIN and IO % ... I don't know what they are, so it doesn't much matter.. :) –  Peter.O Oct 30 '10 at 1:24
    
Glad it works for you. :) –  NightwishFan Oct 30 '10 at 1:28
