show info captured with iostat

The iostat sensor produces this kind of result

Linux 1.2.3-45-generic (blah) 	04/35/2020 	_x86_64_	(8 CPU)

We should show:

  • %iowait
  • %user
  • %system

!! the first block is the value since the boot of the system, which is not interesting => use the second block
