A more civilized iostat, with 100x more precision, and exportable to CSV format.

$ cstat

Just show the busy column, polling every 5 seconds for up to 5 minutes:

$ cstat --poll 5s --for 5m --busy --header=false
10.734
7.532

8.460

Can also show the memory usage, optionally include swap memory with --swap option.
