Display Input and Output (I/O) Statistics with iostat

The input and output (I/O) statistics (iostat) command shows statistics regarding terminal, disk, tape, and CPU activity. I primarily use it in the extended format to monitor CPU and hard disk stats. Here's an example of its use at 3 second intervals.

#iostat 3

#iostat -ctx 3

#iostat -D 3
