This is an updated version of: http://exchange.nagios.org/directory/Plugins/Operating-Systems/Linux/check_iostat--2D-I-2FO-statistics/details

I have added the await to the output as this shows how long the OS spends waiting to write to disk which I think is very important. I have also fixed some bugs so the script now shows the current stats instead of the average stats since boot time

Finally I have created a pnp4nagios template which shows tps on one graph, await on another and read/writes Kb/s on the third.

=== Example usage ====
$ /usr/lib64/nagios/plugins/check_iostat -d sda -w 5000000,10000000,10000000,8 -c 6000000,20000000,20000000,10
OK - I/O stats tps=29.00 KB_read/s=0.00 KB_written/s=460.00 Average_wait/s=0| 'tps'=29.00; 'KB_read/s'=0.00; 'KB_written/s'=460.00; 'await'=0;

Two minor issues. First, script is misnamed (or entry is misnamed), check_iostst.

Second, file is in DOS format. Fix with dos2unix.
